So I saw this on my dash and I had to dig a few articles deep to actually get an explanation of what’s going on.** Solar energy generation, storage, and conversion is something I’ve been studying since about 2015 as a researcher, so I’m always really curious what’s actually new about these articles.
Since even before my time, our field has been pretty adamant that the most important problem we face to a green energy future is how do we store our green energy. We can make tons of it! In fact, TOO MUCH for us to use. We just have no way of storing and delivering it once we’ve made it. People have been working on batteries (solid-state, redox flow...), chemical energy storage (use sunlight to make a chemical reaction that produces a fuel like hydrogen gas, petroleum, methane...), and many other ways to store solar energy for decades and decades.
Besides the fact this is just like, what I do for a job and enjoy thinking about it, figuring out what actual tech is being lauded as Good News was important to me. I (and you) need to know whether this is revolutionary phenomenal more hope for the future kind of good news, or if it was oh hey, this thing we’ve been working on for 20-30 years is finally reaching an almost-market-ready stage (and TLDR: it’s the latter).
So what makes this one newsworthy?
The device developed at Chalmers* is a form of chemical energy storage. Instead of making a fuel to use and burn, the chemical they shine light on purely stores energy, and releases energy. They have recently managed to package it into a neat little chip that takes sunlight, stores it, and then on-demand returns it as electricity that we can use.
-:-
The chemical they’ve used on this chip can exist in two differently shaped forms. And it can change between those forms with a little bit of energy. The researchers determined that the energy requirements for that transformation is small enough that sunlight can perform it.
Tumblr media
So they shine light on one form of the molecule and it turns into the other; it takes the solar energy and “stores” it by resting in that new shape. It’s happy to sit there until they tell it to go back.
When it goes back, it “returns” the initial energy by giving away heat.
They’ve been able to turn heat into electricity somewhat efficiently.
The limitations of this kind of device are:
How much energy you can store is dependent on how many molecules you have on your chip (or in your tub, if you’re doing it in liquid form).
How efficiently you can turn that heat into electricity is a developing technology and they have room to go.
This specific set up requires an *additional chemical*, a catalyst (unsung heroes in most of the press) to help turn the transformed molecule BACK into its original form, the important step to deliver energy back to us! Cobalt(II) phthalocyanine is a known catalyst for these kinds of things and has its own drawbacks.
Doing this in liquid form currently requires organic solvents (in everything in life, we want to use water instead of organic solvents, if possible).
What % of the sun’s light is actually DOING this transformation limits how many of your molecules are actually going to change their shape.While yes, these chemicals do perform this transformation under solar light, specifically they require UV-light. There’s not *actually* a lot of UV light *in* sunlight; ideally, you’d want something that works in visible light (about 40% of sunlight is visible; about 5% is UV). (This is also a major limitation of many other solar technologies.)
Why am I explaining all of this?
I think it’s important for non scientists, particularly those who care about the climate crisis, to have this context. This technology is not a one-off moonshot; this technology is not our best hope; this technology is not the Answer to all our problems; this technology is not unique. The concept itself is also not new. It is not even “in its early stages” as far as research goes. This is a fairly well-developed device and system they are publicizing. It IS in its early stages of implementation.
This is the pace of science. And that should actually give you hope.
It means that for every one individual piece of news you hear like this, there are hundreds of different technologies also being developed, also being worked on, also close to implementation, too. People have been working on these problems, caring about these problems, UNDERSTANDING these problems, for decades even before the public ever caught up. There is progress being made and hope to be had, and nihilism about the climate, about whether The Big Feds and Corporations Are Paying Attention, is both inaccurate and counterproductive.
It IS exciting that this one is working to the degree it is. It IS going to be a useful tool in adapting to our energy needs and making a green future possible. And to me, as someone who’s been watching this field, it’s really exciting and satisfying to know that hey, all this hard work we’ve done uncovering the different pieces of this puzzle..? we’re starting to actually PUT THE PIECES TOGETHER in a functioning way now.
Sometimes even as a scientist, even as someone who understands the pace of research, it can be hard to feel like there’s ever going to be the point where things start working. We’ve been pursuing photoisomerization as energy storage for ages and ages, but it’s never been efficient enough, or we’ve never had a way to release the energy once it’s been stored, or all these other problems. But we’re finally at a point where grit, determination, persistence, and hope, have gotten us through the worst of those issues and gotten some solid footing. And that’s really exciting
-:-:-
*(woo, Gothenberg, they are a hub of green energy development and a bunch of my friends work there. some of them have even worked on related projects as visiting researchers over the years)
**You know what’s really personally annoying about this blurb on tumblr and the euronews article itself??? I had no clue from either of them that I HAVE ACTUALLY REPORTED ON THIS, PROFESSIONALLY. They didn’t link back to a Chalmers press release, or to the researcher’s group websites, or to the papers, in an obvious or accessible way. One of the scripts I worked on last month was literally about this paper and I had to help one of our writers explain what photoisomerization is and thermal electricity generation. It took way too much digging to realize that.
I should have been able to understand from reading this blurb and especially from reading the press release what this actual development WAS.
Good popular-science / general public articles should convey to both non scientists and scientists what the actual technology/research finding is, from the get-go. Anyway, that’s a pet peeve of mine with science communication and with these “hopey fluffy happy science” blogfeeds. You can do better, without descending into the nitty gritty like I did in this longform tumblr post. (And we did, for our show.)

"Probably because they don't have a grave," Danny said, pulling out his vape. "Final resting places are--HEY!"
Nightwing held the pilfered vape above his head. "Where did you get this?" he asked, scandalized.
Danny jumped for it, but Nightwing was too tall! Even at 5'7 he'd have to use his powers to reach the vape; he had no chance as a 9 year old. "We're in Gotham! You're lucky I didn't get cocaine instead!"
