âš¡ A $3 Billion Bet on the Energy Transition

Sequoia Capital closed its third climate technology fund at $3 billion on May 19, 2026, exceeding the firm's original $2 billion target and more than doubling its previous $1.2 billion climate fund raised in 2023. The raise makes Sequoia the largest dedicated climate tech investor among traditional venture firms, surpassing Breakthrough Energy Ventures' $2.5 billion Fund III. Partner Shaun Maguire, who co-leads the climate practice, told limited partners that the energy transition represents "the largest capital reallocation in history" and that Sequoia intends to capture early-stage winners across the entire decarbonization stack.

The fund's investment thesis spans grid-scale energy storage, next-generation geothermal, green steel and cement production, direct air capture, and fusion energy. Existing portfolio anchors include Form Energy (multi-day iron-air batteries with $1.2 billion in booked utility contracts), Fervo Energy (enhanced geothermal with 400 MW under development), and Charm Industrial (biomass carbon removal with 50,000 tons delivered to Stripe and Microsoft).

Sequoia partner Alfred Lin noted that Form Energy's manufacturing facility in Weirton, West Virginia now produces 2 GWh of batteries per year, validating the thesis that climate hardware can achieve manufacturing scale while staying on venture timelines.

📋 Institutional LP Demand Defies Political Narrative

Despite political rhetoric in some jurisdictions opposing ESG and climate-focused investing, institutional limited partners placed aggressive orders for the fund. Lead LPs included the California State Teachers' Retirement System (CalSTRS, $350 million), Canada Pension Plan Investments (CPP Investments, $300 million), and Norway's Norges Bank Investment Management (NBIM, $200 million). Sequoia reported that the fund was oversubscribed by $1.2 billion, forcing the firm to return capital to some existing LPs.

Sequoia's climate funds have delivered a 21% net IRR across the first two vintages, competitive with the firm's core U.S. venture funds and dispelling the narrative that climate investing requires return concessions. "The unit economics of renewables, storage, and electrification are no longer dependent on policy subsidies — they win on cost alone in most markets," Maguire wrote in the fund's annual letter.
