ClearFlame Engine raises $3 million

ClearFlame Engine Technologies, the developer of a new clean combustion engine technology, announced today the closing of a $3 million financing round.

Clean Energy Ventures led the round with participation from several other investors. The funding will allow ClearFlame to accelerate demonstrations of its engine technology. ClearFlame recently completed a proof-of-concept demonstration of their technology on a Caterpillar engine at Argonne National Laboratory and is preparing for a commercial prototype demonstration on a Cummins 15L engine.

ClearFlame’s engine technology easily integrates into existing engine platforms, allowing it to retain the same high torque, fuel efficiency and durability benefits currently associated with diesel engines while eliminating the need for expensive after-treatment installations such as Selective Catalytic Reduction systems.

“Freight transportation and other heavy-duty industries have demanding performance requirements for their engines and tight weight restrictions that make electrification largely impractical,” said BJ Johnson, CEO and co-founder of ClearFlame in an announcement. “We’ve partnered closely with both the public and private sector to develop a combustion engine technology that easily drops into any OEM’s existing diesel engine manufacturing process and distribution supply chain and achieves better carbon mitigation levels than other diesel fuel alternatives like fuel cells. Our technology is designed specifically to serve these heavy-duty and industrial markets and can dramatically and expeditiously reduce emissions.”

The $3M in funding will support ClearFlame as it prepares its technology for pilot demonstrations in the transportation and power generation sectors. The company plans to develop and expand strategic partnerships with OEMs.

ClearFlame Engines has previously received over $2M in non-dilutive grant funding from the National Science Foundation, the Department of Energy, the Department of Agriculture, the Midwest Energy Research Consortium and Stanford University.
