Invests in Heliogen's AI-concentrated solar for industrial heat
Gates backed Heliogen, a company using AI-controlled mirrors (heliostats) to concentrate sunlight to temperatures exceeding 1,000°C — sufficient to replace fossil fuels in cement, glass, and steel manufacturing, which together account for roughly 20% of global CO₂ emissions. Heliogen's approach addresses one of the hardest-to-decarbonize sectors: industrial process heat. The company went public in 2021.

Gates Foundation Awards $4.98 Million to Heritable Agriculture for AI-Driven Climate-Resilient Crop Genomics
In January 2026, the Gates Foundation awarded $4.98 million to Heritable Agriculture — an AI crop improvement company spun from Google X — for the JASON project, deploying a cloud-based AI genomics engine to identify drought and heat tolerance gene targets in staple crops for LMIC smallholder farmers. JASON aims to compress conventional crop breeding timelines and deliver climate-resilient germplasm faster to the nearly 2 billion people whose incomes depend on smallholder agriculture.
