(from press release) – SteelRiver Infrastructure Fund North America (“SRIFNA”) announces an investment in renewable innovator, Davis-based Sierra Energy, acquiring a minority interest in its holding company. Sierra Energy powers homes and fuels cars with waste. Focused on creating carbon-negative energy solutions, Sierra Energy’s FastOx® gasifier is now under construction in partnership with the U.S. Army and the California Energy Commission.

Using steam and oxygen, FastOx gasifiers break down trash into an energydense fuel, without burning. This fuel can then be used to generate electricity or upgraded to renewable transportation fuels such as gasoline, diesel, and hydrogen.

Chris Kinney, CEO of SRIFNA, commented: “We are excited about this opportunity to invest in an environmentally-friendly technology with game-changing implications for sustainable waste management.”

SteelRiver Infrastructure Partners (“SteelRiver”), the controlling affiliate of SRIFNA, is an investment management firm focused on the North American infrastructure with approximately $2.5 billion under management in the transportation and energy infrastructure subsectors. “SteelRiver seeks opportunities to support renewable energy initiatives and innovative clean technology that has benefits for North American infrastructure,” Kinney says.

“We are pleased to team up with a well-respected energy investor who supports our goals of promoting sustainable energy solutions and zero-waste,” observed the CEO of Sierra Energy, Mike G Hart.

Named a ‘Champion of Change’ by the Obama Administration, and an ‘Environmental Hero’ by the U.S. Environmental Protection Agency, Hart is thrilled to see nearly a decade of research, development, and optimization of FastOx gasification cumulate in its full system operation later this year.

Sierra Energy is not stopping at innovating the waste industry. The clean-tech company recently launched, an online sales platform for emerging, clean technologies. Techpipe aggregates demand by giving users early access to innovative technologies.

        Maybe it is private  but the  partnership of  the U.S Army and  the California Energy Commission speaking for itself  that it is expensive source of energy  which is  affordable only for customers like U.S  Army .  I understand that this is pilot project and the U.S Army and the California Energy Commission sponsoring this project. Modified old German technology .
