[00:00:00] Jackie De Burca:下午好,我是建設性聲音欄目的 Jackie De Burca。我和 Naked Energy 工程總監 Alex Mellor 博士在一起。現在,他畢生致力於研究太陽能。他在 PVT 技術、高效能光伏、農村離網系統和太空發電光伏方面擁有兩項專利,發表了 21 篇論文,也寫了一本關於量子太陽能電池的書。現在我可以了。在歡迎您之前,我可以說我曾經住在一個有離網系統的農村地區,所以我很想了解更多關於這方面的資訊。但首先,請你介紹一下你自己,亞歷克斯。

[00:00:48] Dr Alex Mellor: Sure. Hi Jackie. Really, really nice to meet you and thanks so much for having me on your on your podcast. My name’s Alex Mellor. I’ve been a lifelong environmentalist and always had a passion for science and technology. Sort of something of an activist, even when I was back at school. And then when I went to university, I realized that if I chose the right course, I had the opportunity to marry my passions for science, technology and environmentalism. So I studied mathematics and physics with a view to going into renewable energy. I chose to have a year in industry as part of my degree course. And if anyone here is thinking of going to university, they offer a year in industry. I’d really recommend it. It’s a really good way to get started, particularly if they let you choo. Where to go. I found a small PV cell research and manufacture facility in Northumberland in the north of England and I went to did my year internship there. It was called NAREC at the time, they’re now called Solar Capture Technologies. I had a really great experience there and I thought I love research, I love, I love PV solar energy. So I found a PhD in Madrid where I could go and work on high efficiency PV cells, looking particularly at really high efficiency concepts. You know, how to get to 50% electrical efficiency using kind of optical light trapping and device physics. Really enjoyed that. I became a research associate. I then went to Imperial College where I was a research fellow looking at other novel concepts in PV cells. And I started getting interested in PVT and particularly optical coatings for pvt. At that time I was lucky enough to meet Naked Energy where I’m working at the moment. They had a joint project with Imperial College. We worked together on that project and I like the company, the company obviously liked me, so I went to work with them. I’ve been at Naked Energy now for six years. I’m now director of Engineering, I didn’t start that way, but I started working on the product development. We went into commercial phase. So I very quickly became part of a fledgling sales team, set up a kind of a customer journey so we could identify the right kinds of users of solar, heat and PVT technology and take them through a journey. They could see if our technology was right for us. We then hired a proper commercial team, which I was glad of, so I could go back into the technical area. And I now work on a development of the product, a development of our design and monitoring software, and also integration of our technology into building. So that’s a, that’s a kind of brief introduction into my career, which is excellent, Alex.

[00:03:08] Jackie De Burca:我想對於我們的一些聽眾來說,您使用的一些行話可能有點像,好吧,這聽起來很有趣,但那是什麼呢?因此,我想,當我們進行對話時,也許可以嘗試用普通人的語言來表達你所說的一些內容。 Naked Energy 顯然被譽為太陽能創新領域的先驅。亞歷克斯,您能否分享一下公司的使命,以及您認為它在再生能源領域的獨特之處?

[00:03:38] Dr Alex Mellor: Absolutely. So we’re really focused on decarbonization of heat. So, you know, when a lot of people think of renewable energy, they’re really thinking of renewable electricity. Yeah. So if you think of wind power, pv, solar power, these are ways of generating electricity from, from the wind and the sun. But actually most of the energy we end up using, we don’t use as electricity, we use it as heat. Electricity and transport, you know, those are the three main ones. And about 50% of primary energy, we end up using it as heat. So that heats to heat, you know, the spaces that we occupy. So at home or at work, it’s to heat the hot water that we, we bathe and shower in and use for sanitation, and it’s to heat industrial processes so, you know, to make the things that we use. So about 50% of primary energy and therefore of greenhouse gas emissions are to generate some sort of heating or cooling. So that’s really what we’re, we’re aimed at. And we do that through our solar products, which generate solar heat and solar electricity. So we’re attacking both the heat and electricity with our solar products. What, what sets us apart? I mean, we, perhaps less usually for a solar heat technology, we really aim at kind of large heat users. So it’s, it’s commercial and industrial buildings rather than individual homes. So, you know, we Felt there was a gap there and something that was really well served by, by solar heat and power. And we, we designed our technology about how to best deliver for those commercial and industrial end users of heat. And we designed a technology with a very high energy density on the roof. So it’s all about, you know, our customers, they have high heat use, high power use, limited space on the roof, and they want to generate as much as they can with the roof space they have. So we really designed the technology, the, you know, the optics, the heat management, the electrical management, so that we could get the maximum amount of useful energy out of that roof space. And that’s what I’d say sets us apart from other, other solar technologies.

[00:05:38] Jackie De Burca:您指的是 Virtue 技術嗎,Alex?

[00:05:41] 亞歷克斯·梅勒博士:是的,正確。所以我們有兩個技術家族。二者皆稱為美德。其中一種叫做 Virtue Hot,是一種只產生熱量的產品。因此它會產生高達 120 攝氏度的太陽熱量。另一個叫做 Virtue Pvt,這是一個混合單位。因此它既產生熱又產生電能。因此,PV 代表光伏電,就像光伏板一樣,而 T 代表熱能。所以它是pvt,光伏熱能。它既產生電能,又產生熱能。當然,你知道,大多數建築物都需要這兩種能源,所以它非常適合它們。

[00:06:14] Jackie De Burca:那麼我們用外行人能理解的術語來探討一下,Alex,第一個,Virtue pv,它究竟是如何運作的?

[00:06:22] Dr Alex Mellor: Certainly, so it’s Virtue PVT and Virtue Hot. So the Virtue pvt, you have a string of PV cells, you know, they’ll convert sunlight to electricity with about 23% efficiency, which is a standard conversion rate for a PV cell or a PV panel. So if you think of a normal PV panel, it will convert about 20 to 25% of sunlight to electricity. So you’ve got another 75% there. And what’s happening to it? So a small amount is reflected, but most of it is just heating up the panel. So the normal PV panel, most of the sunlight actually just heats the panel and then that heat is lost to the environment and you just have a loss of that useful sun’s energy. What we do in our PVT units is we have a string of 12 PV cells and we run a heating. We have a heat exchanger behind the cells with a fluid channel. So we’re taking the heat off of the cells that was a byproduct of the electricity generation. We’re taking the heat off of the cells and Then putting that down into the building for, you know, useful heat uses. So the things I mentioned earlier, space heating, hot water heating or industrial process heat, uniquely we have the PV cells and the heat exchanger inside an evacuated tube and that’s to keep all of the heat in. So we don’t want to lose any heat to the environment. We want it all going into that fluid channel that’s then taken into the building. And that’s what allows us to operate at temperatures up to around 75C in terms of the PVT, which means we can do, you know, sanitary hot water, low temperature, industrial process heat, which, which makes up a very large part of global heat use. So it’s allows to get a good market penetration and really attack real applications of heat in the virtue hot product, that’s a thermal only product. So instead of the PV cells we have what’s called a selective absorber coating. And that’s very absorptive to sunlight, but it doesn’t emit very much radiation. So you have, as well as reducing the convective loss, evacuated tube, you’re also reducing the radiative loss through that. So that’s heat only, but it generates it in higher quantity and at higher temperatures. That one goes up to 120 Celsius. And both of the products have a very unique geometry using an integrated reflector, which means we maximize the energy density on, on, on an industrial commercial flat roof in particular.

[00:08:36] Jackie De Burca:Alex,您認為裸能源克服了哪些具體挑戰,實現了美德帶來的高碳節約率?

[00:08:47] 亞歷克斯·梅勒博士:謝謝。這其中涉及很多因素。一是設計,特別是光學設計。

所以你知道,你可以擁有沒有任何鏡子、反射或聚光的太陽能,你也可以擁有有反射和聚光並需要你移動和追蹤太陽的太陽能。

現在我們不想有任何移動的部件,所以我們不想有跟踪,不想有跟隨太陽,而是完全靜止的。這樣做的原因是為了成本低且可靠性好。所以我們問自己一個問題,如何從完全靜態的太陽能技術中獲得最大的能量密度?透過這種光學設計,我們最終獲得了非常高能量密度的技術。這就是其中之一。在其餘的挑戰中,很多秘密是什麼呢?這都是關於如何處理真空以及如何在真空內外傳輸不同的能量向量。因此,在真空內部就得到了熱產品和電產品。你需要把熱和電釋放出來。如何在保持良好真空密封的同時,使用低成本的組件和巧妙的工程技巧來做到這一點?因此我認為從技術層面來說,這是兩個主要挑戰。

[00:09:59] Jackie De Burca: That’s a really excellent explanation. TUV certification. Alex Virtue pvt is the first evacuated tube collector to receive this. Can you explain the significance of this certification within the industry and how it enhances the credibility of your own technology?

[00:10:19] 亞歷克斯·梅勒博士:當然。此認證都是根據一系列公認的行業標準進行型式測試而完成的。所以您知道,太陽能熱產品是 Virtue hots 太陽能熱產品。因此這有一套標準。 PVT 既是太陽能熱能產品,也是光伏產品,因此必須遵守兩套標準。所以它要經過非常嚴格的測試制度。好的,您知道,它要經過很多很多測試,但它們大致可分為三類。所以它與安全性、壽命和性能有關。好的,就安全而言,他們會進行測試以確保它具有阻燃性、在乾燥和潮濕的環境下都具有適當的電絕緣性、能夠處理電湧等等,以確保它在屋頂上是安全的並且不會對建築物內的任何人造成風險。在壽命方面,測試的目的是透過短短幾週的測試基本上模擬現場 25 年的壽命。它使用環境室來實現這一點,將我們的 PVT 裝置暴露在非常極端的條件下,比你在現場實際看到的更極端,並且循環非常快,旨在在幾週內重現 25 年後發生的情況。你知道,它是溫度循環從零下 40 攝氏度到零上 85 攝氏度,它是濕度凍結測試,它是極端紫外線測試,它是濕熱測試。他們按照特定的順序進行操作,他們知道這些順序會導致薄弱的技術失敗。正確的。所以它的建造方式會讓你失敗,除非產品非常好。現在我們是唯一通過此認證的真空管PVT技術公司。這對我們來說是一個巨大的里程碑。第三組是表演。

因此,我們當然需要告訴客戶,透過採用我們的技術,他們可以節省多少能源。我們利用該技術的性能數據來實現這一點。這是德國萊茵 TUV 公司在認證過程中進行的三項第三方測試的結果。所以,你知道,他們不相信我們的數據,他們相信我們產品效能的第三方認證數據。因此它具有安全性、耐久性和性能。

[00:12:35] Jackie De Burca:這真是一個令人難以置信且著迷的過程,不是嗎?

[00:12:40] Dr Alex Mellor: Yes. It took us a long time to go through it. We really had to engineer the product very carefully, understand the certification, testing, understand the different risks, make sure that the product was hard to it because you know, you have to spend a fair bit of money to do these tests. It takes a fair bit of time. When you’re going to put your products, you know, they’ll take about 40 products off the line at random and put them through various tests for a kind of a six month program. You want to be very sure at the beginning that you’re going to pass at the end. So you try to reproduce a lot of this in your own lab where you think there’s tests that are particularly difficult to pass. You try and reproduce them as best you can, make sure that you’ve engineered your solution so that when you finally send them to be tested, you’re confident that they’ll come out positively at the other end. And I’m thankful to say that we did so for customers. It gives them confidence in the longevity and the performance of the product and the safety.

In certain geographies it’s a legal requirement to have this certification. Not always and everywhere, but in certain instances it is. And it’s almost always a requirement for subsidies where they are available. So, you know, there’s no subsidies at present in the uk, but you know, in Germany we’re on the BAFA list for the German subsidies. In the Netherlands we’re eligible for the SD Fonshaleur. In France and all over Europe where subsidies are available, because we had the certification, we’re eligible for those subsidies. And of course that’s important for the customer as well.

[00:14:15] Jackie De Burca:Alex,這確實很好地引出了我的下一個問題,從目前的情況來看,這項認證必定會為很多企業打開大門,肯定是在歐洲,甚至可能是在世界各地。

[00:14:28] 亞歷克斯·梅勒博士:是的,絕對是。所以我們現在有 100 個正在進行的項目,我想它們來自 10 到 15,000 個不同的國家。我面前沒有統計數據,但或多或​​少是這樣的。我們已在現場安裝了約 700 根太陽能管,並且我們正在開始擴大專案規模。所以,你知道,當你開始使用一項新技術時,你開始在某人的屋頂上做幾平方米的產品項目,然後你擴展到幾十平方米,然後擴展到幾百平方米。我們在這個領域最大的項目現在有 10 個管道和蓋子,面積約 XNUMX 平方米。我們現在處於設計階段的專案規模是這個數字的兩倍。而且我們還有很多專案正在籌備中,規模是這個數字的 XNUMX 倍。因此,我們在可完成的項目數量和部署的單位數量方面都開始取得進展。這些單一項目的規模非常重要,因為規模越大,您就可以為最終用戶提供更好的價值。我想這也與我們的合作客戶的聲譽有關。我不會具體點名,但許多大型連鎖飯店正在與我們合作,對其投資組合以及許多知名製造業、食品和飲料品牌進行脫碳。所以現在來到 Naked Energy 觀看這一幕真的是一件令人興奮的事情。

[00:15:48] Jackie De Burca:這個等級聽起來很棒。我確實在想這一定是多麼令人興奮。亞歷克斯,你是一個對自己的工作有夢想的人嗎?從個人角度來說?

[00:15:58] Dr Alex Mellor: Yes, absolutely. It’s been, I mean, on a personal level, it’s been kind of interesting journey for me. So, you know, starting out in academic R and D, you work on technology that has what’s called very low technology readiness level. So it’s kind of more blue skies, far reaching, but it’s quite early in its journey. And of all the different technologies people work on in that type of an environment, you know, perhaps 1 in 10 of them or less, you know, actually ends up on a roof generating energy. And that’s a really exciting space to work in. It’s very stimulating. In an intellectual level, it’s a great environment. But if you really want to see your work and innovation on roofs in a shorter space of time. There came a time in my life where it became more exciting to work for a startup company like Naked Energy, where we’re working products that aren’t the future in 20, 30 years, they’re the future in six months to a year. And then actually seeing our innovations on roofs and making a contribution to solving the climate crisis in real time is really, really satisfying. So it kind of, it marries up the mission of addressing an environmental challenge with the kind of intellectual stimulation of being able to work on exciting technology and solve difficult technical problems with the personal satisfaction of being able to work with really excellent people both at Naked Energy on the technical, commercial, marketing and software side. But also the customers we work with are really exciting. They have Their missions that they’re increasingly bought into. Really keen to carbonise their operations and addressing the challenge of how to do that. And if we’re able to offer them part of that solution, it’s extremely satisfying on all sides.

[00:17:48] Jackie De Burca:這是一個歷史性的時刻。當然,亞歷克斯,目前,我想我們可以深入研究一些您沒有提到的名字,但讓我們深入研究一個真正知名的名字,至少在英國或英國。大英圖書館項目,顯然,據我研究所知,這是目前英國最大的太陽能熱能項目。那正確嗎?

[00:18:13] 麥勒博士:是的,我的意思是,這當然是我們的理解,我們的立場是,我們會一直這樣說,直到有人向我們展示更大的答案。

[00:18:21] Jackie De Burca:非常好。

[00:18:22] 亞歷克斯‧梅勒博士:好的,從研究來看,讓我們深入研究一下。

[00:18:27] Jackie De Burca:Alex,實施如此規模的專案面臨哪些後勤和技術挑戰?

[00:18:33] 亞歷克斯·梅勒博士:是的,絕對是。因此,首先要確定熱量的用途是什麼以及如何融入其中。所以這個圖書館真的很有趣。

They have a reasonably high hot water demand as a large building, but they have a high summer demand for heat as well because they have a heat driven humidity control system as well as providing kind of space heating for people in the building. They need to control the humidity because of course they have all the important books and manuscripts, scripts there, of course, and they do that using a heat driven desiccant system. So firstly, understanding that and how we would integrate into it was a challenge.

規劃方面確實存在著有趣的挑戰。那是一級保護建築。是的。當然,我們正在做的是在屋頂和外部建造太陽能電池板。這顯然對規劃有影響。該規劃不僅是透過當地議會完成的,也是透過英國遺產部完成的,因為它是一級保護建築。因此,對你在那裡能做的事情有非常非常嚴格的限制。我們的技術的優點在於它非常低調,距離屋頂 26 厘米,低於女兒牆高度,這意味著從街上看不到它。因此,如果你在圖書館裡走動的話,它是看不見的。這也確實意味著,鑑於該建築的遺產地位,它被允許安裝在那裡。所以這是一個挑戰。

只需將所有材料抬到屋頂即可,要通過一個公眾使用頻繁的廣場,為了完成這項工作,廣場只能關閉很短的時間。這是非常具有挑戰性的。最後一個問題是如何將熱量傳導至整棟建築物。所以,你知道,我們在屋頂上有集熱器來產生熱量,這是我們優質的太陽能集熱器。再往下走大約 200 米,往側面看,就是需要輸送熱量的廠房。就是,就是那樣。因此,讓管道穿過所有不同的樓層、跨越那麼遠的距離並通過靜脈穿透,這是一個非常大的挑戰。

那裡有一個相當新穎的元素。我保證,這將是最後一次。因此,我們總是在我們的系統中安裝散熱器。因此,在熱量需求很少的時候,如果收集器正在產生熱量,那麼你就有地方放置它。如果不能放進大樓裡。我們總是盡量不使用它,因為它只是一種故障保護。你知道,如果每個人都去度假一周或類似時間,而且他們不使用暖氣,但你必須要有一個。而且由於其文化遺產的地位,我們不允許將其放在建築物的外部。因此,它實際上位於內部,並將熱量散發到建築物內部的煙道和煙囪中。所以這是一個有趣的問題的一個非常獨特的解決方案。

We also used their existing pipework and heating system as additional thermal storage, which is interesting. So as well as having a large thermal store, about 15 cubic meters, because they’re running a low temperature hot water distribution system. If you allow that to heat above its set point, you’re also storing energy in that system, which is really interesting because it means you get that storage for free without having to install extra equipment. That was a really nice idea of the designer there. So, yeah, we delivered that project together with PBR and Convert Energy doing the, the install and KJ Tate with the lead designer, we supplied the equipment and did the initial concept for the project. It was a really nice collaboration between some very good companies and some excellent engineers. So, yeah, really, really proud to be a part of it.

[00:22:26] Jackie De Burca: So one of the things that comes to mind obviously sounds really, really fascinating and very intelligently done, but with the challenges that you’ve mentioned, obviously, Alex, but one of the things that comes to mind is how has this advanced the British Library’s sustainability goals and what lessons can other institutions learn from this?

[00:22:49] 亞歷克斯·梅勒博士:所以我相信他們已經能夠將碳排放量減少 15% 左右。

我面前沒有數據。所以它是更廣泛的脫碳運動的一部分。在第一階段,他們安裝了我們的技術,同時也進行了免費通話項目,我認為他們計劃在未來幾年內將剩餘的天然氣電力電氣化。是的,我們為最終用戶提供整體解決方案的一部分。因此,我們的技術將與其他技術一起發展。所以你知道,你可以與熱泵一起工作,與現有的燃氣鍋爐一起工作,以減少這些鍋爐的消耗。通常,最終用戶會擁有某種燃氣加熱系統,他們希望在未來將其電氣化。他們可能希望透過安裝我們的技術來減少當前鍋爐的消耗,然後,當他們最終用電泵或熱泵替換燃氣鍋爐時,我們的技術與新的熱泵一起工作,以減少熱泵的電力消耗。所以這非常好,可以讓你錯開你的脫碳之旅,這對許多活動用戶來說非常有趣,因為他們當然需要在脫碳需求和逐年取得經濟成功的需求之間取得平衡。有時,分階段的方法才能實現這一目標。

[00:24:13] Jackie De Burca:有沒有員工評論說這真的很精彩或與眾不同?您會從那裡的團隊得到任何回饋嗎?

[00:24:21] 亞歷克斯·梅勒博士:是的,是的。我的意思是當我們與那裡的實際圖書館聯繫時。他們對這個項目感到非常興奮。我們還能為他們提供一個很好的監控平台,這意味著他們可以在電腦螢幕上看到它正在生成什麼以及發生了什麼。這非常好,因為這使他們更接近專案了。

您看到屋頂上的資產並問自己它在做什麼?但因為我們可以即時顯示它們,所以這些是千瓦,這些是千瓦時。這就是您的系統目前正在發生的情況。這讓他們感覺更加真實一些。是的,這也是一個不錯的功能。但總體來說,我在圖書館和我們的合作夥伴交談過的每個人都非常非常高興。

[00:25:01] Jackie De Burca: Fantastic. Now going back to the obviously the overarching topic of the decarbonisation of heat. Heat accounts for 50% of global energy emissions and 75% of that is coming from fossil fuels. How does Naked Energies technology contribute to, to Addressing this critical issue, Alex?

[00:25:23] 亞歷克斯‧梅勒博士:是的。因此,它作為新能源結構的一部分做出了貢獻。

所以,你知道,熱脫碳將是不同事物的組合。它將部分地充當熱泵,用於產生熱水和蒸汽。在某些地方和許多其他來源中它將是氫氣,它也將是太陽熱能。

而太陽熱能真正發揮作用的地方就是那些在夏季有熱量需求的熱用戶。因此,無論是商業用戶或需要大量熱水的人,特別是人們居住的地方,例如飯店、公寓大樓、養老院、住宅等等。還有低溫工業製程熱量,因為他們全年都在使用熱量。因此,任何全年使用熱量的地方都是一個很好的應用。太陽能熱的應用可以與現有的化石燃料或熱泵一起工作,或者兩者兼而有之。

與普遍的看法相反,它絕對適用於北方氣候。

因此,如果你看看世界上哪些地方使用太陽能比其他任何地方都多,那實際上是像奧地利和丹麥這樣的國家,這讓人們感到驚訝,因為很多人認為,哦,這只能在南歐和非洲以及 GEC 等地區發揮作用。它確實也適用於極北和極南的氣候。因此它非常適合北歐,當然也適合英國。所以,是的,我認為它發揮著非常重要的作用,而且我認為因為我們正在努力推動這種商業工業應用,所以我認為我們擁有良好的技術,可以發揮非常好的作用。

[00:27:06] Jackie De Burca:顯然,電網在為英國供熱提供電力方面的限制使得太陽能熱能等技術必不可少。您如何看待美德在更廣泛的熱能脫碳策略中對熱泵的補充作用?

[00:27:22] Dr Alex Mellor: Yep. So it can happen at a number of levels, so it can happen on the individual building level. So integrating solar heat with a heat pump works really well and there’s enough as a number of different kind of integration methods you can use. And we have a number of projects in the field where they have a completely off gas system that uses a combination of our solar technology and a heat pump. So that can work really well. You can do it at utility level. So I’ve just come out of a meeting talking about applications for heat networks. You know, they’re building a heat network now in my local town in Worthing, and solar heat can contribute there really well. So it’s reasonable heat network to do maybe, you know, in a climate like the UK, you can do perhaps 20% of the requirement with solar Heat and then balance that with a heat pump or something else. If you’re in Southern Europe, it could be more like 50%.

因此您可以在不同層面進行整合。它可以是建築物級別,可以是公用事業級別,可以是個人住宅,可以是大型商業工業建築。有很多不同的整合選項。

[00:28:33] Jackie De Burca:現在,Naked Energy 正在全球擴張。亞歷克斯,您關注哪些市場,以及如何使技術適應不同的地區和氣候?

[00:28:44] 亞歷克斯‧梅勒博士:是的。

So we’re particularly focused on northern and Southern Europe and North America at the moment. So most of our installs to date, I’d say maybe 80% is the UK and the Netherlands, but we’re starting to have good traction in Germany, in Spain and also in North America. So there’s a manufacturing line starting in the US and a distribution partner there. We’ve had our first project at Creighton University, which is really nice. And I hope we’re moving to Canada as well, because as I mentioned, there is a really good opportunity in northern climate. Our. The fact that we’re an evacuated tube technology means we can operate in those northern climbs, which is really good. And we’re also very hard to high radiation and temperature, so we can also operate in very southern climates. Yeah, so sorry. And I kind of talk with a northern hemisphere bent here. I mean, I mean, I mean, closer to the pole and closer to the equator are both applicable. We have slightly different mounting solutions depending on the latitude. Just because the sun angles are different. Yeah. So we essentially have. We have two types of mountain frame, one from sort of polar latitudes, you know, so either very north or very south. So northern Europe would be an example, or Canada or the northern U.S.

我們還有另一個適合更多赤道緯度的框架,還允許您手動將管子旋轉到最佳角度。因此,透過這兩種安裝類型,我們能夠覆蓋從赤道到北緯 60 度的任何區域,全球 99% 的人口都居住在這些區域。所以它,它,它,它非常適用於所有氣候。

[00:30:38] Jackie De Burca:太好了。那麼,Naked Energy 即將推出哪些創新或專案讓您特別興奮嗎?

[00:30:47] 亞歷克斯‧梅勒博士:是的。因此在專案層面,我們即將開展一個非常創新的專案。我們正在為位於英國中部地區的一個工業基地安裝一台吸收式製冷機,以便能夠透過我們的太陽能加熱產品提供太陽能冷卻。那真是太好了。這是第一階段。然後在該項目的第二和第三階段,我們將使用一種稱為跨季節熱存儲的技術,這使得我們可以在夏天產生太陽熱量,並在秋天和冬天將其用於建築物,方法是將一部分熱量儲存在非常大的罐子裡,將另一部分熱量儲存在地下的鑽孔中。

非常棒的創新項目,解決如何滿足冬季空間暖氣需求的問題?利用太陽能,夏季比冬季產生更多的熱能。這真是令人興奮。

On the product level, we’re now starting R and D into our next generation of products. We’re looking at how to get much higher thermal efficiency in the pvt.

今天正在進行首次生產測試。這真是令人興奮。

對於僅用於熱敏的產品,我們正在考慮透過改變鏡子的角度設計來提高光密度,這樣我們就可以獲得略高的濃度,但不要求進行追蹤。但這可以獲得高效率、更低的溫度和更低的成本。

所以有幾個,有些是產品方面的,但你知道,這些都是我目前佔用時間的事情。

[00:32:23] Jackie De Burca:好的,真是令人興奮,激動人心的時刻。明顯地。

亞歷克斯,您認為廣泛應用太陽能熱能和 PVT 技術的最大障礙是什麼?

[00:32:37] 亞歷克斯‧梅勒博士:是的。

所以部分原因在於文化和觀念。

因此,當艾德·米利班德擔任影子大臣時,我們邀請他來我們的辦公室,我們向他展示了一張非常有趣的圖表,他也覺得很有趣,這是歐洲不同國家太陽能熱能的部署情況。

如果你看看德國、奧地利和丹麥,你會發現,人均部署量是英國的 10 到 20 倍。

但如果你看看這些國家,你會發現氣候極為相似。因此氣候並不是原因。

他們的國家有相似的經濟發展水平,有相似的文化。所以在那裡發生的事情意味著英國對太陽熱的感知與德國、奧地利和丹麥對太陽熱的感知非常不同。那麼,我們如何改變這些看法,以便在我們這樣的國家,我們可以開始做其他地方已經做過的積極的事情。

透過向人們提供優質、可靠的技術。我們也討論了認證問題。它旨在為最終用戶提供適當的監控包,以便他們可以確信他們正在產生所承諾的能量。

透過這樣做,您就開始為太陽能熱能建立良好的聲譽,並讓人們看到它的潛力。我認為,我們正朝著這個目標邁出好的一步。是的,請說。

[00:34:11] Jackie De Burca:對不起,這是我的錯。我有點興奮,純粹是因為我可以說,你知道,我在西班牙已經用了五六年了,沒有什麼比知道你除了利用我們可用的能源之外什麼都不做更美妙的了。

[00:34:29] Dr Alex Mellor: It’s very satisfying, isn’t it? And it’s the distributed nature of it as well. That’s very nice. It’s not renewable energy that’s being generated hundreds of miles away and then being mixed with all sorts of other types of energy and non renewable and then being kind of wired into you. It’s happening on the roof where you are. It’s very pure and democratic way of generating energy.

[00:34:52] Jackie De Burca:絕對是。那麼展望未來,您認為未來五到十年 Naked Energy 和再生能源產業將會發展到什麼程度?

[00:35:06] 亞歷克斯·梅勒博士:是的。所以正如我所說,我認為,熱量是每個人都面臨的巨大挑戰。我認為這一點在北歐和美國已經得到了很好的實現。所以你知道,我們必須這樣做,你知道,當我開始在 Naked Energy 工作時,我覺得我必須教育每個人關於再生熱能的重要性。而現在,有客戶來找我們,說我們需要減少加熱中的碳排放。所以這種範式的轉變正在快速發生,這是非常好的。僅從我們客戶的行為、合作夥伴的行為來看我們周圍發生的事情,我真的認為你有統計數據而不是我,傑基,但我不記得你說的熱量中有多少百分比是由不可再生能源產生的。那是在 80 年代。

[00:35:56] Jackie De Burca:我認為是 50%,我想是的。

[00:35:58] 亞歷克斯‧梅勒博士:50% 是我們用來當作熱量的能量。但我認為,在那 50% 中,我認為,我認為其中幾乎 90% 是存在的。

[00:36:05] Jackie De Burca:75。

[00:36:06] 亞歷克斯·梅勒博士:來自化石燃料。

[00:36:07] Jackie De Burca:是的,就是這樣。

[00:36:08] 亞歷克斯·梅勒博士:是的,是的,我確實看到這一數字正在下降,是的,有了 Naked Energy,我認為我們在這方面發揮著越來越重要的作用。我的意思是,你知道,我們是眾多公司和眾多技術之一,每個人都在為解決氣候問題做出貢獻。但我越來越覺得我們正在做出一個重要的決定。

[00:36:30] Jackie De Burca:當然了。絕對地。是的,這是令人興奮的時刻。顯然,有時我們會在新聞中了解到這些事。好吧,如果我們不知道正在發生的這些其他非常非常積極的事情,很多日子可能會有點令人沮喪。如果您能向那些猶豫是否採用再生熱能技術的政策制定者或企業提供一條建議,您會說什麼?

[00:36:53] 梅勒博士:我想說,環顧世界,看看哪些是成功的,哪些是失敗的,看看哪個國家真正成功地運用了一項技術,例如丹麥和奧地利的太陽能熱利用。問問自己為什麼會這樣,並嘗試在自己的地理位置重現這種情況,並用這個例子來反駁那些說「哦,你知道,這項技術不適合這裡」的同事。

[00:37:17] Jackie De Burca:完美。

現在,最後的想法。你的工作最能激發你的靈感是什麼?我想我們已經討論過這個問題了。但是,您知道,您在「Naked Energy」中所做的事情,最能激發您的靈感的是什麼嗎?您想給我們的聽眾留下什麼訊息呢?

[00:37:34] 亞歷克斯‧梅勒博士:當然了。

所以對我來說,我在一開始就提到了這一點。這是任務刺激和人員。

我的意思是,這是在那個空間工作的情況。這就是你所得到的。

使命,解決氣候危機,刺激,透過解決困難的技術挑戰來實現這一目標。然後還有人們,你知道,與你一起踏上這段旅程的無數不同的人,既有 Naked Energy 的人,也有我們的合作夥伴和客戶。這使得它成為一個真正令人興奮的工作空間和一個偉大的工作場所。這就是我早上起床的動力。

[00:38:12] Jackie De Burca:最後,我想我必須為您添加一條,因為您的簡歷中包含了一些工作,這些工作將包含在這裡的程序頁面上。你確實有一個兒子,不是嗎?

[00:38:23] 亞歷克斯‧梅勒博士:是的,沒錯。

[00:38:24] Jackie De Burca:所以這也一定非常像,你知道,與你擁有的所有動機交織在一起。

[00:38:30] 亞歷克斯·梅勒博士:是的,絕對是。

你知道,幾年前我生活中有一段時間一直關注環境和氣候危機。但我認為,我認為在年輕的時候這是一種智力上的關注。這是你腦中產生的擔憂。

我認為近年來,部分原因是隨著年齡的增長,部分原因是看到周圍發生的事情,你會開始產生一種更情緒化和本能的擔憂,你開始想,這實際上會影響我的孩子和我們的家庭,這對他們意味著什麼,而不是,這已經發生了。你知道,後代這個概念看起來很抽象,不是嗎?

但是當你開始從你周圍成長的人的角度來考慮這個問題時,不一定是你自己的孩子,只有你,你生活中周圍的年輕人,我想,你會開始擁有更多。對氣候變遷意味著什麼的更本能的焦慮。

你知道,這很可怕。

[00:39:38] Jackie De Burca:對很多人來說都是如此。但是你所參與的工作非常重要且鼓舞人心。

[00:39:44] 亞歷克斯·梅勒博士:說實話,參與這場鬥爭來感覺真的很好。你知道,現在有這麼多人參與這場鬥爭。這太棒了。

[00:39:52] Jackie De Burca:就是這樣。所以,聽著,這真的很有趣,很令人著迷,我真的很感謝您抽出時間。

[00:40:00] 亞歷克斯梅勒博士:非常感謝您邀請我參加節目。傑基,很高興與您交談。

[00:40:03] Jackie De Burca:非常感謝。亞歷克斯喜歡智慧。這是建設性的聲音。
