3 takeaways about climate tech right now

We knew we wanted this list to reflect China’s emergence as a global energy superpower, and we ended up including two Chinese firms in key industries: renewables and batteries.

In 2024, China accounted for the top four wind turbine makers worldwide. Envision was in the second spot, with 19.3 gigawatts of new capacity added last year. But the company isn’t limited to wind; it’s working to help power heavy industries like steel and chemicals with technology like green hydrogen.

Batteries are also a hot industry in China, and we’re seeing progress in tech beyond the lithium-ion cells that currently dominate EVs and energy storage on the grid. We represent that industry with HiNa Battery Technology, a leading startup building sodium-ion batteries, which could be cheaper than today’s options. The company’s batteries are already being used in electric mopeds and grid installations.

2. Energy demand from data centers and AI is on everyone’s mind, especially in the US.

Another trend we noticed this year was a fixation on the growing energy demand of data centers, including massive planned dedicated facilities that power AI models. (Here’s another nudge to check out our Power Hungry series on AI and energy, in case you haven’t explored it already.)

Even if their technology has nothing to do with data centers, companies are trying to show how they can be valuable in this age of rising energy demand. Some are signing lucrative deals with tech giants that could provide the money needed to help bring their product to market.

Kairos Power hopes to be one such energy generator, building next-generation nuclear reactors. Last year, the company signed an agreement with Google that will see the company buy up to 500 megawatts of electricity from Kairos’s first reactors through 2035.
