Awards season is upon us, and I can’t get enough. Red-carpet fashion, host drama, heartwarming speeches—I love it all.
I caught the Golden Globes last weekend, and the Grammys and Oscars aren’t far off. But the best awards, in my humble opinion, are the 10 Breakthrough Technologies, MIT Technology Review’s list of the tech that’s changing our world.
This year’s list dropped on Monday, and I’m delighted to share that not one, not two, but three climate tech items are featured. So for the newsletter this week, let’s take a look at a few of these award-winning technologies you need to know about. (And to honor awards season, I’ll also be assigning them to bonus—and completely unofficial—categories.)
Super-efficient solar cells
Winner: Best Supporting Actor
Solar panels are among the most important, and perhaps the most recognizable, tools to address climate change. But one next-generation solar technology could help solar power get even more efficient, and cheaper: perovskite tandem solar cells.
Most solar cells use silicon to soak up sunlight and transform it into electricity. But other materials can do this job too, including perovskites, a class of crystalline materials. And because perovskites and silicon absorb different wavelengths of light, the two materials can be stacked like a sandwich to make one super-efficient cell.
Because of their outstanding support for traditional silicon solar materials, super-efficient perovskite tandem cells are my winner for this year’s Best Supporting Actor award.
There are definitely barriers to commercializing this technology: perovskites are tricky to manufacture and have historically degraded quickly outside in the elements. But some companies say they’re closer than ever to using the materials to transform commercial solar. Read more about the technology here.
Enhanced geothermal systems
Winner: Best New Artist
Sucking heat out from the earth is one of the oldest tricks in the book—there’s evidence that humans were using hot springs for heat more than 10,000 years ago.
We’ve since leveled up, using geothermal energy to produce electricity. But a specific set of factors is needed to harness the energy radiating out of the planet’s core: heat close to the surface, permeable rock, and underground fluid.
This narrows the potential sites for usable geothermal energy significantly, so a growing number of projects are working to widen access with so-called enhanced geothermal systems.
An enhanced geothermal system is essentially a human-created geothermal energy source. This often involves drilling down into rock and pumping fluid into it to open up fractures. We’ve seen some recent progress in this field from a handful of companies, including Fervo Energy, which started up a massive pilot facility in 2023 (and made our list of 15 Climate Tech Companies to Watch).
Because of its spirit of reinvention and innovation, enhanced geothermal systems are my pick for this year’s Best New Artist Award.
Some of the biggest projects coming are still a few years from coming online, and it could be tough to scale construction on these plants in some places. But enhanced geothermal is definitely a field to keep an eye on. Read more in my colleague June Kim’s write-up here.
Winner: Lifetime Achievement
Last, but certainly not least, we have the venerable heat pump. These devices, which can cool and heat using electricity, are a personal favorite climate technology of mine.
Heat pumps are super efficient, sometimes almost seeming to defy the laws of physics. They don’t really break any laws, physical or otherwise, as I outlined in a deep dive into how the technology works last year.
While they’re not exactly new, heat pumps are definitely breaking through in a new way. The technology outsold gas furnaces for the first time in the US last year, and sales have been climbing around the world. Globally, heat pumps have the potential to cut emissions by 500 million metric tons in 2030—as much as pulling all the cars in Europe today off the roads.
For their long-standing and ongoing contributions to decarbonization, heat pumps are my choice for this year’s Lifetime Achievement Award.
It’s going to be tough to get heat pumps into all the places they need to go to meet climate goals. For more on all things heat pumps, check out my write-up here.
Congratulations to all our winners! Be sure to check out the rest of the list. It includes everything from wearable headsets to innovative new CRISPR treatments.
And if you’d like to weigh in on one more award, you can vote for our reader-chosen 11th breakthrough technology here. The candidates are some of the other items we considered for the list. I don’t want to unfairly influence you, but you know my heart always goes with batteries, so feel free to vote accordingly …
It’s been a turbulent time for offshore wind power. Projects are getting delayed and canceled left and right, it seems.
In 2024, some big moments could determine whether these troubles are more of a bump in the road or a sign of more serious issues. For everything you should watch out for in offshore wind, check out my latest story here.
