ClearFlame Technologies, which hopes to take the "diesel fuel out of diesel engines," announced this week it has raised $30 million in Series B funding to bring to market innovative solutions that power heavy-duty engines with clean, renewable fuels and create a viable business solution to reduce carbon and soot.

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 continues gaining momentum with technology that heavy-duty equipment users can deploy to more quickly and affordably meet critical ESG goals,” says BJ Johnson, ClearFlame CEO and company co-founder. “Federal Department of Energy funding moved us from concept to patent. Series A funding propelled us from patent to pilot. This latest investment round can accelerate us from pilot to proven product in multiple markets, starting with long-haul trucks.”

The company’s patented technology runs on a range of renewable liquid fuels. It can efficiently adapt to markets like long-haul trucking, offering the same power, durability and performance as today’s diesel engines while readily integrating into existing manufacturing, fueling, maintenance and repair ecosystems. In pursuit of penetrating the more than $200 billion global trucking market, the company is piloting five trucks in collaboration with some of the largest fleet operators in North America. It is also exploring partnerships and applications for the mining, agriculture, and power generation sectors.

Johnson and ClearFlame CTO and co-founder Julie Blumreiter dedicated their doctoral research at Stanford University to finding solutions to mitigate climate change and achieve carbon reduction goals by freeing heavy-duty diesel engines from their reliance on fossil fuels.

Diesel fuel consumption accounts for approximately 26% of overall CO2 emissions from the U.S. transportation sector. While electric powertrains face significant barriers for heavy-duty applications, the technology ClearFlame developed can meet heavy-duty performance requirements while offering better lifecycle greenhouse gas emissions reduction than EV by nearly 61% using lowsoot renewable fuels. A total cost of ownership study prepared by industry analysts Gladstein, Neandross, and Associates found that using ClearFlame engines would reduce lifetime ownership costs for fleet operators.

“The effort to achieve a sustainable clean energy and fossil-free future has to be inclusive and comprehensive,” says Blumreiter. “We welcome all partners who see our innovation as a means to make tomorrow’s ESG goals today’s realities.”
