Climate tech funding is rebounding, led by AI-enabled infrastructure, data centers, and adaptation, while investors remain more selective and focused on unit economics.[1][4] Clean energy and grid technology are still drawing major capital, but policy uncertainty is shaping what gets financed and how quickly projects move forward.[3][4]

•Startup funding and market trends

•Venture and growth investment in climate tech rose 8% to $40.5 billion in 2025, with a record 179 funds raising $92 billion in new capital.[1]

•U.S. climate tech VC investment reached $29 billion in 2025, the third-highest year on record, according to Silicon Valley Bank.[4]

•Nearly 28% of climate equity dollars went to AI-enabled solutions, and data centers attracted nearly $2 billion on their own.[1]

•Adaptation funding increased 64%, reflecting growing investor focus on physical climate risk and resilience.[1]

•Notable climate tech startups and developments

•Antora Energy has raised more than $230 million total, including a $14.5 million ARPA-E SCALEUP award; it is already operating a thermal battery unit delivering 24/7 industrial heat and power from renewables.[2]

•Form Energy announced a 300 MW / 30 GWh deployment with Xcel Energy to help power a Google data center in Minnesota, described as the largest battery energy storage system by energy capacity ever announced.[2]

•Quaise Energy reached 118 meters of millimeter-wave drilling in granite in 2025 and is building Project Obsidian in Oregon, targeting a 50 MW initial pilot with commercial operation by 2030.[2]

•Twelve expects its AirPlant One facility in Washington to begin production in 2026; it is positioned as the first commercial facility to make E-Jet fuel at scale, with purchase interest from Alaska Airlines, IAG, Microsoft, and the U.S. Air Force.[2]

•Clean energy and environmental innovation

•The strongest financing continues to cluster around grid, storage, industrial decarbonization, and low-carbon fuels, especially where technologies can serve power-hungry infrastructure like data centers.[1][2][3]

•Climate adaptation has shifted from a niche to an asset class, driven by hotter conditions and operational risk.[1]

•SVB reports that 52% of climate tech companies reduced net burn year over year, suggesting a broader move toward efficiency and profitability.[4]

•ESG and investment climate

•ESG and climate investors are operating in a more disciplined market, with capital increasingly favoring technologies that can show near-term deployment, durable margins, and clearer revenue paths.[1][4]

•The funding environment is also being influenced by policy headwinds, which are delaying projects and increasing uncertainty.[4]

•Policy and regulatory backdrop

•Trellis notes that the U.S. federal government’s One Big Beautiful Bill Act and related policy direction helped unlock some wait-and-see capital, though the broader effect has been uneven across the sector.[1]

•SVB says there have been 50+ federal actions since 2024 that have created headwinds through changes in funding, research support, permitting, and staffing.[4]

•Sector signal for today

•The clearest near-term winners are AI-related climate infrastructure, long-duration storage, industrial heat, and sustainable fuels, while policy volatility remains a material risk for scaling.[1][2][4]
