“We are delighted to be partnering with Equinor and Chevron in helping to bring Sapphire’s clean energy technology to a global market,” said Adam Mikkelsen, Principal at Cooper and Company. “Sapphire’s technologies combine zero carbon electricity with compelling economic returns, and we believe we’ll see widespread adoption within the energy industry.”

“Equinor’s ambition is to become a net-zero energy company by 2050, and new solutions and technologies will be required for society at large to meet its climate targets. We are pleased to announce the investment in Sapphire as one contributor to help the energy industry reduce emissions and improve energy efficiency,” said Gareth Burns, Head of Equinor Ventures.

“Sapphire’s FreeSpin expander technology enables waste energy recovery across multiple industrial applications, potentially reducing carbon emissions while increasing operating efficiency,” said Barbara Burger, Vice President of Innovation and President of Technology Ventures for Chevron. “This is the latest investment from our $300 million Future Energy Fund II, launched in February 2021, which focuses on industrial decarbonization, emerging mobility, energy, decentralization and the growing circular carbon economy.”
