Clean Energy Ventures

Deal flow comes through a shared sourcing and diligence network with the Clean Energy Venture Group, an affiliated angel network of former operators, engineers, and energy executives. The Group scouts seed-stage climatetech companies and often co-invests alongside the fund. This structure gives institutional limited partners early access to technologies that the operator network has already vetted commercially and technically.

The Clean Energy Venture Group is a sister organization of angel investors with deep operating experience in the energy and environmental sectors. It provides seed capital and management expertise, and CEV and the Group support each other in sourcing, scouting, and diligencing deals. They frequently co-invest, effectively creating a continuum from angels to institutional venture capital.

Yes, the firm publicly states that every startup it backs must demonstrate the potential to achieve multi-gigaton-scale greenhouse gas emissions reduction within three decades of investment. This quantifiable impact filter is applied during due diligence and is central to the firm's investment thesis.

A Strategic Advisory Board chaired by former U.S. Secretary of Energy Ernest Moniz advises on portfolio company strategy, emerging technologies, and industry trends. The board also includes Dr. Ellen Williams, former director of the DOE ARPA-E program and former chief scientist at BP, J. Michael McQuade, former CTO of United Technologies, and Girish Nadkarni, former president of TotalEnergies Ventures.

The firm often acts as the first institutional venture capital backer for its startups. It has led or actively structured early-stage rounds for companies such as Noon Energy and LineVision, frequently syndicating with the Clean Energy Venture Group and other corporate and financial venture investors including Aramco Ventures, National Grid, and bp Ventures.

Clean Energy Ventures invests across North America and Europe, with headquarters in Boston and a presence in London. Portfolio companies are based in both regions, and the firm has supported European startups such as OXCCU, a UK-based company making sustainable aviation fuel from CO2 and water in a single step.

The team, composed largely of trained physicists, engineers, and former founders, provides hands-on assistance with IP co-development, talent acquisition, strategic marketing, and active board participation. A network of 19 Venture Partners with deep technical and operating backgrounds assesses, builds, and mentors management teams at portfolio companies.
