Cutting the Carbon Footprint of your Energy Supply
Hit play on this episode of 'Ask The Expert' as we discover the importance of technology such as heat pumps in decarbonising your energy supply.
The UK has set a legal deadline to achieve Net Zero by 2050. Some industries have set even earlier targets. This means that every business needs to play its part in minimising its carbon footprint.
Energy supply is one of the most significant contributors to carbon emissions, so businesses need to take steps now to reduce energy consumption, improve efficiency and lower costs and carbon emissions. Hybrid energy solutions that incorporate a range of energy sources, including technology like heat pumps, can meet all of your requirements.
Decarbonising Our Energy Supply - Transcription
00;00;01;19 - 00;00;26;18
Speaker 1
Good afternoon, everyone, and welcome. My name is Martyn Fuller and it's my pleasure to be your host for today's broadcast. When I'm not doing this, I'm the head of marketing proposal, responsible business here, very UK of Veolia. Our ambition is ecological transformation. Using the products and services we already have to tackle the environmental challenges of our customers and innovating new solutions to protect, preserve and provide access to resources for all.
00;00;26;21 - 00;00;51;07
Speaker 1
Tomorrow. Tomorrow is tomorrow. But today we are discussing a very important topic, decarbonization, and more specifically, how we can decarbonize our energy supply to make way towards net zero. I hope you are going to find it engaging. I hope you are going to find it interesting. And in a moment, I'll be welcoming my two guests for today. Danny Edelman and Heather Foster first.
00;00;51;08 - 00;01;11;22
Speaker 1
Decarbonization is a word that I think if I'd seen it written down two or three years ago, I would have checked to see if it wasn't a spelling mistake. Now it's a word I use probably every hour of the day. It's constantly something we are trying to achieve. But what is decarbonization? Decarbonization? We're going to find an awful lot more about today.
00;01;12;06 - 00;01;36;07
Speaker 1
But in simple terms, it's reducing the carbon dioxide emissions through the use of low or zero carbon sources in issues like energy production, concrete production, everything that we do that requires some sort of fuel. To put this into context. I heard this analogy recently and it stuck in my mind. Imagine a grid. 100 dots by 100 dots. That's 10,000 dots.
00;01;37;05 - 00;02;08;21
Speaker 1
Every breath you take, you inhale those 10,000 dots for the entirety of humankind's history. Three of those dots were carbon. Until recently, a fourth dot of carbon appeared. That's a 33% increase. We are approaching a point in time where five dots would be carbon. We hit that point. Systems collapse. Systems change. This is to be very clear. Something that is very important and I really hope you take something from our conversation today.
00;02;10;08 - 00;02;31;12
Speaker 1
Let me be clear about something else. We don't need to save the planet. The planet will be fine with six, seven, eight, nine, ten dots. It's our society and our species that we need to save. Obviously, we have products and solutions that can help to decarbonize our customers' systems and processes. Tell me tell you how we do that.
00;02;31;15 - 00;02;38;02
Speaker 1
I'm joined today by two of the earliest decarbonise aviation experts, Heather and Danny. Danny changes yourself first.
00;02;39;14 - 00;02;45;26
Speaker 2
Good. Good afternoon. And my name is. I'm the technical director for energy at Veolia.
00;02;47;22 - 00;02;50;15
Speaker 1
Hi, Danny. Heather, tell the world who you are.
00;02;51;20 - 00;02;59;05
Speaker 3
Hi, I'm Heather Foster. I'm the sector lead for healthcare, education and public sector projects. And earlier.
00;03;00;08 - 00;03;18;17
Speaker 1
Fabulous. Thank you for joining me this lunchtime, guys. I hope it's not going to take too much time out of your day, and I hope you enjoy yourselves, too. I'm going to start asking you some questions. And you know me. We've known each other a long time and are always going to be the most straightforward. And you're going to have to help me out with your answers, because sometimes I don't understand things.
00;03;19;17 - 00;03;29;23
Speaker 1
So, Heather, I'm going to come to you first. Why is it important for businesses to take action now if they haven't already started to do so to decarbonize their energy supply?
00;03;31;10 - 00;04;03;13
Speaker 3
Well, we've all experienced some rather warm temperatures this week, I think. And I read something this morning that that could be the norm for us, for our children. So there's that personal responsibility and this does that. Then there's the corporate responsibility. So a number of organisations are looking for suppliers to demonstrate environmental, social and corporate governance regarding sustainability and decarbonisation.
00;04;04;03 - 00;04;25;25
Speaker 3
And then there's the sort of financial element. So at the moment, there are funding streams, available incentives in different sectors. So it would be a good idea to take advantage of those now. And while they're available and help your organisation achieve net zero or work on the journey to net zero.
00;04;27;15 - 00;04;56;05
Speaker 1
Thanks, Heather. Is there any other angle to this? I mean, it just occurred to me as we were talking there, you know, the crisis we're undergoing in the east of Europe and fossil fuels and things like that. Is there a decarbonization argument, not just about the climate, not just about protecting the environment, but also about energy sovereignty and actually, you know, being less effective, impacted by other countries and the supply of fossil fuels.
00;04;56;28 - 00;05;25;12
Speaker 3
Yeah, there's you know, there's the opportunity to generate some of your own energy on site and then there's and such as Peavey to provide electricity. And then there's the opportunity to reduce your consumption. So less reliance on those fossil fuel technologies and which would help you decarbonize as well. So lots of lots of options.
00;05;25;23 - 00;05;44;27
Speaker 1
There's a lot of upsides to this, isn't there, when you think about it in the old. It's a system, isn't it? The externalities drive. The drive is forward. Danny, can I come to you and ask you a question now, please? I want to know, can you give me an example of a puce or green solution? And how do solutions work?
00;05;44;27 - 00;05;57;14
Speaker 1
I've heard of heat pumps, for example. How do they contribute to a business's decarbonization efforts and how can they be combined with other energy sources to create a bespoke, maybe personalised solution? Is that something that's possible?
00;05;58;27 - 00;06;37;26
Speaker 2
Yes, absolutely. There is no one solution that fits all for decarbonisation. And we usually take a holistic approach and almost work backwards from effectively how the energy is used on a particular site, whether it's a building or whether it's a process or both. And then working backwards from that to the distribution and then only then the production of, of the energy and sometimes all where all the way up to the way the air and the energy is procured as well.
00;06;38;15 - 00;07;13;17
Speaker 2
So yes, the heat pump and the world of the decade is often part of the end of the solution, but it's not what I would call a yellow page, a solution. We can just want one or two of those. As you said, it's usually part of a group of solutions and where we've got to use a bit of innovation, not rocket science as such, but effectively being able to look at the expertise and the experience that we've got.
00;07;13;23 - 00;07;48;24
Speaker 2
And in other sectors, sometimes in other applications, sometimes in other countries where Veolia is and to be able to happily copy and adapt a solution that has worked and to be able to find. So we combined and sometimes even retrofit a heat pump combined with a CHP that may already be installed on a site and install some photovoltaic panels.
00;07;50;23 - 00;07;55;28
Speaker 2
So it's looking at it as a whole as that's a holistic approach.
00;07;56;28 - 00;08;18;24
Speaker 1
There's a system, isn't it? So, you know, one of the great sayings of the naysayers is that wind doesn't work and solar doesn't work as the sun doesn't shine in which the rain doesn't always flow and things like that. And, the wind is always blowing. But, you know, having a balance and having a whole system solution inside it, I think that's what I'm hearing that you're telling me it works and it's part of the solution, is that.
00;08;19;24 - 00;08;49;10
Speaker 2
Absolutely. But it's really a thinking of starting from the beginning, which is how and how the energy is used. Sometimes it needs to rethink a process or a look at the building fabrics to say what can be and what can be insulated. Sometimes replacing windows to ensure that we, first of all, drive the energy consumption down before or at the same time as addressing the disruption and the production of fabrics.
00;08;49;11 - 00;09;09;03
Speaker 1
So we have a building or a site on an energy diet to effectively get them to any of the calories they need. I'm I, I've just come up with a new analogy here. I may have got a book out of this. I've patented that. That's my new analogy. I'll work on it. I'm interested in heat pumps because I've heard different types of heat pumps.
00;09;09;11 - 00;09;27;11
Speaker 1
I've had a groundswell of heat pumps, air source heat pumps. And I'm a little bit I'm going to say not even a little bit. Okay. So I'm guessing squashes the air a bit and you get a bit of a high temperature because of pressure. Thank you, Mr. McGill. I do remember some physics, but what sort of temperature increases can you get?
00;09;27;11 - 00;09;31;00
Speaker 1
And can you tell me what the difference is between a ground citizen and an air source heat pump?
00;09;31;27 - 00;10;08;18
Speaker 2
Okay. So basically ground source heat pump is part of a little bit of black magic when we talk about it to effectively take a low grade energy like in the water, in the aquifers at possibly around 15 degrees. And being able to boost that to a much higher temperature sometimes up to 80, 80, 85 degrees, sometimes you have got to do things first of all, to advance 55 of them from 55 to 2 to 80.
00;10;08;18 - 00;10;33;20
Speaker 2
So that's when we talk about that ground source, heat pumps and otherwise, air source, heat pump. Again, that can be a single stage where we boost that from the outside, the temperature from even five degrees or 15 or 20 degrees outside and boost heat to 70 degrees. Or again, if we use two stage heat pumps and two, the more traditional way to do 80, 80, 85 degrees.
00;10;35;00 - 00;10;53;15
Speaker 1
To some questions in a little while, because I'm now beginning to see things so effectively from a tepid cup of tea or to a nice hot brew is possible, and that's quite amazing to me. That really does get me thinking about this. Heather, I'm going to come back to you and Denise, just give me a brilliant answer there.
00;10;53;15 - 00;11;18;14
Speaker 1
And, you know, like a competition. So the games on I'm now beginning to think, you know, it's great that we talk in theory it's great that we you know text book of what about in reality how can businesses start to think about and can you give some examples of where businesses are starting to think about improving their energy efficiency going on the OR Martin's patented energy diet and reducing their consumption.
00;11;18;22 - 00;11;23;13
Speaker 1
You know, can you give me some examples of that in those businesses and those steps they've taken?
00;11;24;20 - 00;11;29;20
Speaker 3
If we talk about your diet, we need to understand where the calories are being consumed.
00;11;30;12 - 00;11;33;01
Speaker 1
This is taking off this idea, isn't it? You're running with it.
00;11;33;19 - 00;12;01;25
Speaker 3
Yeah. So the first thing really is, is metering to understand where the energy is being used. So we found some organisations are not sure how much electricity they're consuming into buildings or how much heat they need. And so that's probably a first step to understand what they are using and then what they need. So is it for heating, is it for water?
00;12;01;25 - 00;12;32;08
Speaker 3
Is it for a process? So we work with a lot of hospitals and they sterilise the surgical equipment by steam. So we talk a lot about the steaming and conversion from steam systems to low temperature hot water systems. And that's a way to help the hospital on their decarbonisation journey. So hospitals still may want or need some of that steam for some of their process in their sterilisation.
00;12;32;21 - 00;12;45;00
Speaker 3
So it's understanding that if the hospital or the organisation understands first how much energy they need and where they're using it, then that's the first step to understand it.
00;12;45;01 - 00;13;04;22
Speaker 1
Yeah, you've got to understand the obvious. So that's the first act. But what's, you know, how can Veolia help in that? Is there anything we can do to support that? And what sort of I'm imagining if I was a procurement person and I was having to think about this, are people worrying about funding? Is that how I pay for this?
00;13;04;22 - 00;13;06;20
Speaker 1
These sort of things? Can we do that?
00;13;07;05 - 00;13;35;24
Speaker 3
Yes. So we can support applications for funding. There's a few different initiatives at the moment. Recently there was the Low Carbon Skills Fund, and we can help with that from the public sector and also the public sector decarbonization scheme where we've helped a number of hospitals and trusts apply to that funding and for decarbonization schemes. So we can work at all levels really.
00;13;35;24 - 00;13;51;26
Speaker 3
We can help at the initial stage to understand demands and consumption and then we can right through to partner in to design in building, installing and operating and maintaining the equipment and to a holding.
00;13;52;11 - 00;14;13;20
Speaker 1
Holding the hand of the customer. I guess that's I'm hoping that somebody's going to be sitting there and thinking and feeling reassured that there is somebody that you can help and it's yourselves. I'm thinking of some of you initiatives and the other projects we do, and one of the things that we have to come across is, as any might get involved in cloud based producing content for educational purposes.
00;14;13;20 - 00;14;24;21
Speaker 1
And I'm guessing that we all, although we're all like maybe waste away and we're all water aware of turning taps on these, do you think there's an educational piece as well that can be supported. It needs to be delivered.
00;14;25;15 - 00;14;58;08
Speaker 3
Yeah. And that's something that organisations can do in-house or again, we can support on the education pitch piece. We've got the I think our ITRs out of decarbonization guide is very popular download it from our website. If anybody is interested in that. But then there's the behaviour change like you say. So educating people to turn lights off and looking at different systems to see, well, is that room being used?
00;14;58;12 - 00;15;23;24
Speaker 3
We need the heating and the electricity, the lighting on if nobody's using it and that kind of thing. And we can support, you know, we support the huge number of organisations up and down the UK, everything from food and beverage manufacturers to hospitals that I mentioned to science parks. So we've also got data so we can help people benchmark or compare that use to others and to say, well, you know what?
00;15;23;28 - 00;15;27;00
Speaker 3
What would you expect from a drinks manufacturer?
00;15;27;10 - 00;15;48;22
Speaker 1
Yeah, that's really interesting. And Danny, I'm coming to you because up I'm getting this picture of the ability we have to help customers best understand because they need to know if you don't know where you're aiming for you don't know where you start. You've got to start somewhere. And knowledge is power in that sense.
00;15;49;04 - 00;16;10;07
Speaker 1
And then beginning to understand that, we've got to understand how much energy you're going to have to produce. You have to get back to a multi diet. You have to take the operation down to, okay, let's get you lean and ready for the competition, ready for the play by doing some of the simple things I think.
00;16;10;07 - 00;16;29;01
Speaker 1
Danny, you mentioned fabrication of the building and at the you've talked about, you know, the simple things which you light off and things like that but I'm guessing then you've got a lot of data. You know, we've already talked about data about what you've got, data about your options, all the different training and all the education you got.
00;16;29;01 - 00;16;43;20
Speaker 1
I'm guessing companies like some, they go snow blind and suddenly go hot and wet. Starting was my priority. So, Danny, what would you think in your experience, your expertise? What is the biggest priority for businesses trying to decarbonize their energy supply?
00;16;43;20 - 00;17;12;21
Speaker 2
So we've already talked about reaching for the low hanging fruit. And so the field is one of the organisations that can really help with identifying that if that's not already been done, these behaviours, which we talked about, are very important. Once that has done it's really you're looking at an energy map on site.
00;17;12;21 - 00;17;44;22
Speaker 2
And when we talk about energy, we're talking about energy and resources. Because for us at Veolia and water and waste or energy or gas and buildings, all of that constitute a resource that can actually be used for producing the end energy. So we need to have the map on the side. And until the energy crisis effectively turning a tap or opening a switch or a compactor was taken for granted.
00;17;44;22 - 00;18;17;13
Speaker 2
Now we've got to understand exactly how that is distributed. How is that mapped? One is its map is to avoid being overwhelmed by the data. We're converting the data into true information to say, okay, what are the options and is that available to the client? What's the impact on the site or the production depending on the different solution without affecting the resilience, that is always a top priority for our customers.
00;18;17;19 - 00;18;48;18
Speaker 2
And also looking at the construct ability, whether we work in a hospital, whether we work in manufacturing and process and ensuring that whatever solution in that is implemented recommended or agreed with our customer is not affecting the patient, the public, the production manager and so that's through our experience of being able to come up with a plan of implementation in the short term, but also in the long term.
00;18;49;03 - 00;19;04;15
Speaker 2
That's what the decarbonization plan is all about: options and maintaining steel resilience, looking at the construct's ability to avoid impacting customers and they and the customer the public.
00;19;05;03 - 00;19;19;12
Speaker 1
I want to wave a big flag there. I'm going to call out the marketing. You're telling me we can do decarbonisation when you talk about the hospital? I mean, you can't you can't shut down the wing of the hospital, can you? You can't do it.
00;19;19;25 - 00;19;20;27
Speaker 2
No.
00;19;20;27 - 00;19;26;23
Speaker 1
No, you can't. So you tell me that that's happened. That's something that is taking place. We've oh.
00;19;26;23 - 00;20;03;08
Speaker 2
Absolutely. We have a good example of a recent hospital where we managed within less than a year to complete this team. And the hospital installed 44 pretty changers in 12 rooms and without impacting the operation of the hospital, the public, the nurses and the patients it is all prime and I'll prime expertise. Our prime remit is to build to do that being completely transparent and to the customer.
00;20;05;06 - 00;20;05;24
Speaker 1
That's still.
00;20;06;10 - 00;20;19;28
Speaker 2
Up to between 500 in that particular hospital. It's 800 tonnes, but it can go sometimes depending on the application up to 2000 tonnes of CO2 saved as a result of this plan.
00;20;20;17 - 00;20;46;10
Speaker 1
So it's possible. Yes. So, you know, if we're steaming an entire hospital yet keeping them still able to to help and serve and care for the patients, it's almost as if, you know, with the right planning and the right processes that you and Heather are discussing it, there's an awful lot that's possible. So it's not a question of, oh, will, we can, we'll have to wait till tomorrow or next week, next year, 2030 to start.
00;20;46;22 - 00;21;10;10
Speaker 1
It is possible for the organisations to start now without having an impact on what they're actually trying to do. I think that's inspirational for me and I'm guessing policies and we've already talked about funding energy policies we've been in full time but you know the government has committed to targets. So these energy policies are going to be coming in and more of them are going to come in and ramp up.
00;21;10;10 - 00;21;14;05
Speaker 1
I guess, in terms of impact, would that be right?
00;21;14;05 - 00;21;48;26
Speaker 2
Yes, absolutely. We've got a team within our energy market that is keeping very close to and base, in particular, to be aware of not only all the energy policies that are coming and that's changing rapidly, but also looking at the incentives. And it's a maze to understand what are the incentives or funding opportunities that all are available to make the changes less and more digestible.
00;21;48;28 - 00;21;50;06
Speaker 2
They seem to be talking about diets.
00;21;50;16 - 00;22;16;08
Speaker 1
It's something that all of you know. That's great. I get it. I think so. So what I'm hearing, I'm still hearing that everything's in a good place. Heather, I'm coming back to you now. And I'd like to try and imagine I'm the customer. You know, it's the first visit, you know, what does that how do you approach to the expertise?
00;22;16;08 - 00;22;30;07
Speaker 1
How are your first steps? What's it going to be like for somebody who maybe listens back to this and says, you know, I'd like to meet with Veolia and understand what's up. First minute that first meeting, first time together, going to be like, what's what's the approach?
00;22;31;10 - 00;22;58;08
Speaker 3
Well, I can see the Veolia values behind you. MARTIN And one of them is Focus, which is they just step out of the screen, walk in. That's to go to the screen to listen to the customers really is the first thing we do. So to go in, listen, usually someone myself or someone from my team and someone from Danny's team and to understand their requirements.
00;22;58;08 - 00;23;38;05
Speaker 3
So is it that they're trying to achieve net zero by 2014 and which quite a lot of public sector organisations are? Or is it 2050, which is the sort of general UK target and what's that consumption which we talked about earlier that they're metering and then to understand what their existing equipment looks like. So have they got 40 year old boilers that are not operating as efficiently as they could be and we could look to replace them or break them or have they got a CHP unit already that is providing them we pay and we could make a better use of that heat?
00;23;38;16 - 00;24;08;05
Speaker 3
And what's their travel and transport plan? Can we support them by putting EV charging points and solar panels and that kind of thing? So it's understanding and their masterplan for the site, are they going to be developing bigger, bigger sites or reducing the site? So understanding their drivers and then talking to them about the options that Denise, that does not there's not one solution that fits everybody.
00;24;08;05 - 00;24;13;09
Speaker 3
There's different options that we pick out depending on what the customer's requirements are.
00;24;14;13 - 00;24;37;22
Speaker 1
Fabulous. Thank you for that. You know what? For a first meeting with the salesman, I don't feel too bad. Should I go? Well, so, yeah. I'll have three now. That's really helpful. And I think it's good for people to know what's coming out of this conversation. For me, as a lot is possible right now too, there's a lot of support out there to deliver this.
00;24;37;22 - 00;25;01;25
Speaker 1
And there's people like you, companies like Veolia, who have got an awful lot to offer. So there is no fear of having that first conversation. I think that's really important. I'm going to try and get my marketing card absolutely thrown and torn up and ripped out here with this question for you today. One of the most shameful things I think exists is the word carbon footprint.
00;25;02;04 - 00;25;29;22
Speaker 1
Not many people may know carbon footprint was a marketing word. It was a marketing phrase by BP in order to push the carbon issue to the consumer rather than the producer. It doesn't work. We're all a bit wiser now, but can we be accused of the same thing today? Do we practice what we preach? We're sitting here saying, Oh, we customers, you should do this, you should do that, you should do the other.
00;25;30;24 - 00;25;45;18
Speaker 1
We can come to your site and help you with this one. Scott two Veolia still are doing a lot of work and I've got an awful lot of facilities and offices. What are we doing about our carbon footprint? How are we decarbonizing our processes and facilities?
00;25;46;24 - 00;26;37;06
Speaker 2
Yeah, absolutely. As you mentioned, it's extremely important, not only because we believe in ecological transformation and the importance that it has for the world we are applying to ourselves, what we are preaching to others and what we are offering to our customers. So starting with the same terms of behavioural and launching campaigns too, it sounds simple, but ensuring that we switch lights that are rebuilding energy management systems are tuned so that it doesn't consume an energy at night when the buildings are not occupied, and looking at the insulation of all buildings and ensuring that the windows and roofs and those are all of the core examples.
00;26;37;07 - 00;27;06;27
Speaker 2
So these are the whole process we're going through. But in the end, we're not going to have to do that tomorrow. We've got a plan which we have proudly put on our website. It's easy to say it's not only a requirement, but also we're proud to say that we have got our plans to decarbonize by 2050 and with some details of how we anticipate doing that, we're also looking at we've got our own biogas production on our waste water Council.
00;27;07;03 - 00;27;42;04
Speaker 2
We're looking at what can be done with biogas in the future. And we've started to electrify some of the issues, collection and vehicles and looking at how we can push for relevant companies to be electric as well. So we are applying ourselves. I didn't mention solar, but obviously it is a bit it's trying to fit and carport already is solar as much as we can on our depots and offices.
00;27;42;15 - 00;27;48;27
Speaker 2
So again, it's a whole series of solutions that, well, apply to ourselves.
00;27;50;13 - 00;28;14;14
Speaker 1
That's good enough. That's good to know. I appreciate that. Well, we're coming to the end of our time together. And I want to close out with a question to both of you. I'm going to start with you, Heather, and then maybe you can do anything you want to add, because we've all heard, I think for a long time the word hydrogen and hygiene to me would sound like it's a decarbonise.
00;28;14;14 - 00;28;21;26
Speaker 1
Is it let's just use, is there a role for hygiene play in decarbonizing energy? What do you think, Heather?
00;28;22;25 - 00;28;51;10
Speaker 3
And I think like you say, it's a bit of a trendy word, hydrogen. It will eventually be a key player. And at the moment, it's not readily available. And we're preparing by installing hydrogen ready boilers, hydrogen ready technology. So we're ready for it. And we're working closely with organised nations, including universities, on things like the various hydrogen hopes and clusters.
00;28;51;18 - 00;29;15;16
Speaker 3
And people may have heard of high net and those sort of locations. So we are keeping up to date and it is going to be and eventually a key part of decarbonization. And as I say, we're installing technology that's ready for it and we're not quite there yet today. What do you think?
00;29;16;01 - 00;29;50;06
Speaker 2
Yeah, I would just add that Seddon and many of our customers are sitting on, for instance, the OECD, the high net network, and we've got a big role to play to ensure that when hydrogen is passing by, the curbside, that that we will help our customers move towards that technology, ensure that it is done as our specialty in a non disrupting manner to their process or to their activities.
00;29;50;15 - 00;30;11;29
Speaker 2
And we've demonstrated that we can do that with good knowledge of how to keep well informed with the different technologies and with our supply chain. And indeed in terms of the project management to ensure that went to reality. And we will help our customers switch to hydrogen if it's.
00;30;12;04 - 00;30;34;15
Speaker 1
Excellent at yeah, it's cost effective and everything is. And so guys, you, you've, you've educated me. I feel educated. I feel like I understand. I enjoyed being a customer for a moment. And I hope that anybody who is taking the time to spend time with us this lunchtime and anybody who will listen back to this in the future will also appreciate it.
00;30;34;15 - 00;30;38;10
Speaker 1
So thank you ever so much. Thank you, both of you, for your time.
00;30;40;11 - 00;31;15;25
Speaker 1
And if any questions come in, people know how to contact me. We'll be seeing that happen more and more now. After these, I will be touched. So thank you. But for the rest of you, you can join our next live link team, which is taking place on Monday, the 15th of August at 12 p.m.. We're continuing with our decarbonization theme and we're going to be looking at the first of a two part series on decarbonizing transport and be joined by David Reynolds from the Midwest facility that specialises in electric vehicle battery recycling.
00;31;16;07 - 00;31;35;21
Speaker 1
This is a huge topic. There's a lot to talk about, I'm sure I will be using the word black mass at some point. And if that doesn't get the algorithms running, nothing will. So thank you for your time today. Thank you, Heather. And thank you all for joining us today. I look forward to speaking to you all. Say goodbye.
00;31;37;02 - 00;32;09;04
Speaker 2
Bye.
Sustainable Energy Solutions
Solar panels and wind turbines have long been the symbols of greener, cleaner energy. But there are other proven technologies that are being adopted to help drive us towards a lower-carbon future, such as:
How does hydrogen work as a fuel?
Hydrogen offers a clean, highly efficient fuel source that creates minimal carbon emissions, and it is being speculated that it could be our main fuel source in a decade's time.
There is much discussion around blue and green hydrogen (and the numerous other colours), and the differences between them. Blue hydrogen comes from natural gas being split into hydrogen and carbon dioxide, with the CO2 being captured and then stored. Green hydrogen, on the other hand, is generated from surplus renewable energy and is ultimately seen as the most desirable option, although at present it is the most expensive. Using direct onsite combustion, hydrogen is able to be utilised as a fuel source.
How can hydrogen be utilised in your organisation?
With hydrogen still just in the discussion stage for many, there may be understandable reluctance for organisations to think about investing in it. Rather than thinking about introducing hydrogen immediately, an option for organisations is to make sure equipment is hydrogen-ready.
How Do Heat Pumps Work?
Heat pumps work by extracting energy from the surrounding ground, air or water, and transferring it from one area to another. In a process similar to a refrigerator or air conditioning unit, extremely cold fluid circulates through tubes in the heat pump’s external network. This is then vaporised and compressed to generate heat.
The process works as follows: extremely cold fluid circulates through tubing in the heat pump’s external network. This fluid absorbs the heat from the surroundings which then vaporises the fluid, and compressing this generates heat. In summer these systems can act as air conditioners by taking energy from inside buildings and moving it outside, giving heat pumps a dual purpose.
A Carbon-Neutral Process
Although a good way of decarbonising a heating supply, heat pump systems do consume a significant amount of electricity, for example for three units of heat energy produced by a typical system, around one unit of electrical energy will be consumed. By using renewable electricity the system becomes carbon neutral, which is exactly what we've done for a number of district heating schemes. We've pioneered the use of heat pump systems that take heat from wastewater to provide heat for homes, and we power these systems by generating renewable electricity from biogas extracted from the same wastewater. This produces 2.9MW of heat and 1MW of electricity, to create a complete carbon-free heating solution for communities.
It's not just communities that can benefit from heat pump solutions. Buildings that use a lot of heat, such as hospitals, can also utilise them as part of their decarbonisation strategy. Veolia has a number of heat pump projects that are ready to support the NHS on its journey to a low carbon future. Similarly, university campuses are looking at lowering their carbon footprint with this approach.
