The SWAN Impact Network is pleased to announce a recent follow-on investment in ClearFlame Engine Technologies, part of a larger raise of $30M in Series B funding for the company.

The latest investments were led by Mercuria Energy Group, one of the world’s largest privately held energy and commodities companies, with Mercuria and Breakthrough Energy Ventures both making second investments. New investors, including mining corporation Rio Tinto, and WIND Ventures, the strategic venture arm of Copec, one of Latin America’s leading mobility and energy companies, see ClearFlame as part of a holistic suite of strategies to advance environmental, social and governance (ESG) goals.

ClearFlame Engine Technologies significantly reduces GHG emissions for long-haul trucking, agriculture, power generation, and other sectors by transforming heavy-duty engines to run more cost-effectively and cleaner on 100% renewable, plant-based fuels.

SWAN previously invested in ClearFlame Engine Technologies in 2020 and 2021.
