On October 21, 2025, Arbor Energy, a clean energy startup developing modular carbon-free gas turbines, raised $55 million in a Series A funding round co-led by Lowercarbon Capital and Voyager Ventures. The funds will support completing a 1 MW pilot and developing a commercial 25 MW turbine system called HALCYON, which can run on natural gas to biomass fuels, targeting utility and industrial applications[1].

In 2025, early- and growth-stage climate tech investment totaled $13.2 billion in the first half of the year, down 19% from 2024, reflecting a cooling market and policy headwinds such as rollbacks of some Inflation Reduction Act incentives under the Trump administration. Despite this, sectors aligned with AI, data centers, nuclear energy, geothermal, energy storage, and carbon capture are gaining traction. A notable 109 startups applied to Trellis’s 2025 climate tech showcase, collectively raising over $750 million[2].

US climate tech funding reached $15.3 billion in the first half of 2025, up from $11.4 billion in the same period in 2024, with a shift toward later-stage investments. Series B deals increased by 26.8%, and Series C and later rounds jumped 33.3%, indicating investor preference for technology-ready companies. Early-stage funding declined, with seed and Series A deals down by about 12% each[4].

Key climate tech investors active in 2025 include Ecosystem Integrity Fund, Clearvision Ventures, and Halogen Ventures, focusing on Series A to growth-stage investments across climate, energy, sustainability, and related sectors[3][5].

On the policy and support front, the Maryland Department of Commerce launched the Climate Technology Founders Fund (CTFF) in October 2025, an 8-month program to prepare Maryland-based climate tech startups for investment. The fund emphasizes diversity, supporting startups with at least 40% underrepresented founders, including women, minorities, and veterans. It also requires founders to raise external capital or invest personal funds, aiming to catalyze market growth and foster a resilient clean energy ecosystem[7].

In terms of carbon impact metrics, Arbor Energy’s HALCYON turbine aims to be carbon-free and fuel-flexible, potentially reducing emissions by replacing conventional fossil fuel turbines in utilities and industry[1]. Broader climate tech investments increasingly focus on technologies with measurable environmental impact, such as carbon capture and clean energy generation[2][4].

Overall, the latest developments show a maturing climate tech investment landscape with significant funding for advanced clean energy technologies, a shift toward later-stage deals, ongoing policy-driven support programs emphasizing diversity and readiness, and a focus on impactful environmental innovations.
