Climate Tech Startups

Climate tech funding matured in 2026, reaching $40.5 billion globally in 2025 (up 8%), with larger investments in proven technologies like AI-powered solutions for data centers and decarbonization.[2] Key startups to watch include:

| Startup | Focus | Funding | Key Details |
|---------|--------|---------|-------------|
| Antora Energy | Thermal batteries for industrial heat/power | >$230M (Series B 2024 + $14.5M ARPA-E) | Stores renewable heat in carbon blocks; backed by BlackRock, Breakthrough Energy Ventures.[1] |
| Solugen | Bio-based chemicals from renewables | >$600M (Series D 2025) | Replaces fossil chemicals; US DOE grant for Bioforge plants.[3] |
| CarbonCapture | Modular direct air capture (DAC) | $35M (Series A 2023) | CO₂ removal via renewables; pilots for carbon removal demand.[3] |
| Fervo | Geothermal energy | $462M (Series E Dec 2025) | Powers Google data centers; filed for IPO early 2026.[5] |
| BeZero Carbon | Carbon credit ratings | N/A | 40% price premium per rating; covers 480+ projects, 100+ subscribers like UBS.[1] |
| Voltpost | EV charging via streetlights | ~$3.6M (Seed 2024) | Urban pilots in major US cities.[3] |

Other notables: Synspective (radar satellites for climate monitoring),[4] Planet Savers (DAC spin-off).[4] Y Combinator funds 49 climate startups as of April 2026.[8]

Trends: Sodium-ion/iron-air batteries, 95% material recycling, grid tech for AI/data center demand.[6]

Clean Energy

•Geothermal: Fervo tops US greentech lists; Google signs 150 MW deal with Ormat.[5]

•Nuclear fusion: Helion (backed by Sam Altman) hits 150M°C milestone in Polaris reactor.[5]

•Batteries/Storage: Startups target abundant materials, solid-state tech, grid flexibility amid electrification surge.[6]

•Aviation: Zero-emission focus via investors like Japan Airlines.[1]

ESG Investing

Big Tech drives decarbonization: Google acquires Intersect ($4.75B), invests in Fervo/Ormat; corporate subscribers (UBS, Equinor) boost BeZero ratings for CORSIA compliance.[1][5] Investors favor fewer, scaled firms.[2]

Climate Policy

•ARPA-E SCALEUP: $14.5M to Antora for thermal storage.[1]

•US DOE grants: Accelerate Solugen's chemical plants.[3]

•CORSIA Phase 1: Aligns voluntary/compliance carbon markets.[1]

Environmental Innovations

•Soil/Ag: Biome Makers uses AI/DNA for regenerative farming, emissions cuts.[3]

•Microplastics: Calyxia (French) raises $35M for pollution tech (2024, ongoing relevance).[7]

•Carbon registries: Expand to supply-chain decarbonization.[2]

•Monitoring: Synspective satellites for floods/landslides.[4]

No specific April 25, 2026, announcements; summaries draw from recent 2026 outlooks. Carbon metrics limited: BeZero enables premiums, DAC targets scalable removal.[1][3]
