8 Rivers Capital, a North Carolina-based firm focused on the innovation of sustainable, infrastructure-scale technologies, has been awarded seven US Department of Energy (DOE) grants worth over $30m to develop carbon capture technologies for clean electricity.

The new capital will help the firm advance the Allam-Fetvedt Cycle, Lime Direct Air Capture, and its own Carbon8 technologies, continuing 8 Rivers’ ten years of advancing the global energy transition.

8 Rivers is partnering with a number of carbon capture experts to deliver its multi-million-dollar suite of projects. The company’s partners include:

  • General Electric (GE): The Allam-Fetvedt Cycle optimised for high-variable renewable energy.
  • MIT: Negative carbon electricity from retrofit carbon capture and direct air capture.
  • National Renewable Energy Lab (NREL): Development of novel combustion codes for sCO2 combustion.
  • Parametric Solutions, Inc. (PSI): Building the world’s first syngas-fuelled sCO₂ combustor.
  • Southwestern Research Institute (SWRI): Renewable energy storage through the Allam-Fetvedt Cycle.
  • SWRI: Develop a detailed design for a sCO2 oxy-fuel turbine for syngas and the Allam-Fetvedt Cycle.
  • UNOTech: Novel phase-change post combustion capture process for existing gas power plants.

“By making clean cheaper than dirty, the 8 Rivers technology platform creates the economics that allows the world to achieve net-zero emissions by 2050,” said Bill Brown, CEO at 8 Rivers Capital.

“Our mission is social at its very core: the world can only achieve its climate goals if we drive the cost of electricity down to the level that every human being can afford.”

“We are grateful for the opportunity to work on seven projects with our world-class partners at GE, MIT, NREL, PSI, SWRI, and UNOTech, advancing the DOE’s goals for carbon capture and the world’s goals for hitting net-zero emissions.”
