95 Industrial Decarbonization Startups to Watch (#308)

Industrial emissions make up roughly a quarter of global CO₂ emissions, yet many of the most promising climate tech companies remain largely unknown outside specialized circles. This episode explores 95 startups attacking some of the hardest decarbonization challenges across steel, cement, chemicals, heat, fuels, mining, and manufacturing. In addition, I cover one startup turning solar into a 24/7 firm, clean power. Industrial heat is becoming a major battleground — Companies are replacing fossil-fuel-fired boilers and furnaces with thermal batteries, electrified heat systems, and long-duration energy storage solutions. Cement and concrete innovation is scaling — Startups are reducing process emissions through alternative chemistries, carbon mineralization, supplementary cementitious materials, and low-carbon production methods. 24/7 solar and clean power are emerging as a new category — Companies are combining solar, storage, and dispatchable energy systems to deliver around-the-clock clean electricity rather than intermittent renewable generation. Steel and metals are entering a new era — Entrepreneurs are commercializing green hydrogen, electrolysis, scrap optimization, and novel production pathways to lower emissions from some of the world's most carbon-intensive industries. Chemicals and fuels are being reinvented — Companies are developing sustainable feedstocks, e-fuels, carbon utilization technologies, and alternative chemical manufacturing processes. The winners may not be the most obvious companies — Industrial markets reward reliability, economics, and operational simplicity, meaning some of the biggest future climate tech successes may emerge from sectors receiving far less attention than AI, EVs, or consumer technologies. -- 1️⃣ Join our confidential CEO community.
