Today’s climate-tech and sustainability news is centered on a rebound in climate venture funding, rising attention to AI-linked infrastructure, and continued momentum in industrial decarbonization and carbon removal.[1][3]

•

Climate tech funding is recovering

Global venture and growth investment reached $40.5 billion in 2025, up 8% from the prior year, and climate funds raised a record $92 billion across 179 funds.[1]

•

AI and data centers are reshaping climate capital flows

Nearly 28 cents of every climate equity dollar went to AI-enabled solutions, while data centers attracted nearly $2 billion on their own.[1]

•

Adaptation is becoming investable

Funding for climate adaptation rose 64%, reflecting investor focus on physical-risk resilience rather than only emissions reduction.[1]

•

Policy is influencing capital allocation

Trellis says the market shifted after the U.S. federal government enacted the “One Big Beautiful Bill Act”, which signaled which climate policies it would support, helping unlock sidelined capital.[1]

•

Critical minerals remain a strategic theme

Trellis highlights projected 30–40% deficits in copper and lithium by 2035, reinforcing demand for materials innovation and domestic supply chains.[1]

•Form Energy remains one of the most closely watched grid-storage startups: one report says it raised a $405 million Series F, bringing total funding to more than $1.2 billion.[3]

•Form’s iron-air battery has also been tied to a reported ~$1 billion Google payment for a system capable of delivering 300 MW for 100 hours, and its active-development pipeline reached about 750 MW / 75 GWh by April 2026.[3]

•In another 2026 startup roundup, Form is described as preparing a 300 MW / 30 GWh deployment with Xcel Energy to support a Google data center in Minnesota, described there as the largest announced battery system by energy capacity.[2]

•Heirloom reportedly raised $150 million in Series B and has raised $203 million+ total across eight rounds.[3]

•The company is developing two Louisiana facilities with combined capacity of 320,000 tons per year, and one is due to come online in 2026.[3]

•Heirloom is also pursuing a sub-$108/ton cost target for carbon removal, which would materially improve the economics of direct air capture if achieved.[3]

•Lilac Solutions has raised $145 million in Series C, for $318 million total funding, and remains a key lithium-extraction startup tied to critical-minerals supply.[3]

•Antora Energy is also drawing attention for thermal storage: its commercial unit at Wellhead Electric near Fresno is described as the first thermal battery to provide 24/7 industrial heat and power from renewables in an operating setting.[2]

•In industrial decarbonization, Sublime Systems is cited as having raised over $200 million and secured binding contracts, including a long-term agreement with Microsoft for low-carbon cement.[3]

•Twelve is expected to begin production at its AirPlant One facility in Moses Lake, Washington in 2026, with the plant described as the first commercial facility to produce e-jet fuel at scale.[2]

•Broader startup trends point to more funding in battery storage, grid reliability, flexible load shifting, and critical-mineral supply chains, driven by rising electricity demand from electrification, AI, and data centers.[5]

•Environmental innovation is also spreading into food, transport, and shipping, including vertical farming, precision agriculture, electric trucks,
