Climate Tech Startups and Funding

Major 2025 funding rounds highlight AI-integrated climate tech, with Fervo Energy raising $462 million in Series E for next-gen geothermal power using oil-industry drilling for 24/7 carbon-free electricity, backed by Bill Gates's fund and serving clients like Google.[1] Base Power secured $1 billion Series C for home-battery leasing to build distributed grid storage, led by Addition and investors including Andreessen Horowitz and Google’s CapitalG.[1] Unconventional AI led with $475 million seed for energy-efficient, biologically inspired AI computers.[1]

A $300 million fund by the All Aboard Coalition (managing $60 billion assets, including Breakthrough Energy Ventures, Khosla Ventures) targets "missing middle" climate tech scaling ($100–200M rounds) for manufacturing and prototypes amid Q2 2025's global funding dip to $5.9 billion.[2] US climate tech hit $15.3 billion in H1 2025 (up from $11.4B in 2024 H1), with later-stage deals surging 33.3% and industrial decarbonization at 19.3% of funding.[4]

Student-led startups in emerging markets can apply for $100,000 MIT Climate & Energy Prize (deadline Jan 11, 2026) targeting adaptation in developing countries facing a $310B annual gap by 2035.[3]

Clean Energy and Environmental Innovations

Geothermal (Fervo) and grid storage (Base Power) dominate, alongside direct air capture (Climeworks, $1B total raised) and hydrogen aviation (ZeroAvia, $1B).[5] Industrial decarbonization surges with low-carbon materials, efficiency software, and electrification.[4] YC funds 49 climate startups; databases track 2,955 with $30.1B aggregate.[5][7]

ESG Investing and VC Trends

US leads with 51% global funding ($21.4B); Europe rebounds expected.[2] AI climate optimization (e.g., Anthropic $13B, xAI $5.3B) redefines VC priorities, blending profitability and sustainability.[1] Key VCs: DCVC, Energy Impact Partners, Liquid 2 Ventures.[2][9] Top US firms: Crux Climate, Palmetto, TerraPower, Helion Energy.[10]

Climate Policy

Limited specifics; developing countries get <10% adaptation funding, fueling youth-led innovation demand.[3] Federal R&D slowdown challenges capital-intensive scale-ups.[4]

No December 28, 2025-specific news; summaries draw from late-2025 updates (e.g., Dec 23–26).[3][5][6] Carbon impact metrics sparse; geothermal targets grid-scale zero-emission power.[1]
