GoKawiilMIT Technology Review names Brimstone among 10 climate tech firms to watch
MIT Technology Review has included US startup Brimstone in its 2026 list of 10 Climate Tech Companies to Watch, a subscriber-only feature. Brimstone produces lower-carbon cement alongside critical minerals, using silicate rocks instead of limestone to cut emissions from the cement-making process by about 60%. Separately, the publication's upcoming print issue explores the technical and political hurdles to building a self-sustaining lunar base.
GoKawiil's interpretation of the reporting above, not reported fact.
Cement production is a major source of global carbon emissions, so a process that cuts emissions while also yielding critical minerals could appeal to both climate-focused and resource-security-focused buyers, straddling different political priorities in the US. The moon base piece suggests that even with technologies like autonomous robots and nuclear power in hand, political cooperation may prove the harder problem to solve than engineering.
- Brimstone is named one of 10 climate tech companies to watch in a 2026 report by MIT Technology Review.
- Brimstone's cement process uses silicate rocks instead of limestone, cutting emissions by roughly 60% while also producing critical minerals.
- A separate report argues political will, not just technology like robots and nuclear power, is the main barrier to building a sustainable lunar base.
