Raven SR, Chevron and Hyzon Motors collaborate to produce hydrogen from green waste in Northern California
10 January 2023
Raven SR, a renewable fuels company; Chevron New Energies, a division of Chevron USA; and Hyzon Motors are collaborating to commercialize operations of a green waste-to-hydrogen production facility in Richmond intended to supply hydrogen fuel to transportation markets in Northern California.
The facility will be owned by a newly formed company, Raven SR S1 LLC. Raven SR will be the operator of the facility, which is targeted to come online in the first quarter of 2024. Chevron holds a 50% equity stake in Raven SR 1. Raven SR holds a 30% stake and Hyzon owns the remaining 20%.
To produce the hydrogen, the project is expected to divert up to 99 wet tons of green and food waste per day from Republic Services’ West Contra Costa Sanitary Landfill into its non-combustion Steam/CO2 Reforming process, producing up to 2,400 metric-tons per year of renewable hydrogen.
Diversion of this organic waste will help fulfill California SB 1383 mandates, and will potentially avoid up to 7,200 metric-tons per year of CO2 emissions from the landfill. In addition, Raven’s technology uses no fresh water, an important element given drought risks in California, and uses less electricity to power its units than competing processes.
The project is expected to produce at least 60% of its own electricity by upgrading the currently permitted and zoned landfill gas electric generators at the landfill, further reducing both the current air emissions and the need for grid power for its non-combustion process.
Chevron plans to market its share of the hydrogen in Bay Area and Northern California fueling stations, enabling the energy transition to zero emission vehicles. Hyzon, a global supplier of fuel cell electric commercial vehicles, plans to provide refueling for hydrogen fuel cell trucks at a hydrogen hub in Richmond.
Ahead of teaming with Raven SR on the Raven SR S1 facility, Chevron and Hyzon were among Raven SR’s initial strategic investors, along with ITOCHU, Ascent Hydrogen Fund and Samsung Ventures.
The Raven SR technology is a non-combustion thermal, chemical reductive process that converts organic waste and landfill gas to hydrogen and Fischer-Tropsch synthetic fuels. Unlike other hydrogen production technologies, its Steam/CO2 Reformation does not require fresh water as a feedstock and uses less than half the energy of electrolysis. The process is more efficient than conventional hydrogen production and can deliver fuel with low to negative carbon intensity.
Additionally, Raven SR’s goal is to generate as much of its own power onsite as possible to reduce reliance on, and/or be independent of the grid. Its modular design provides a scalable means to locally produce renewable hydrogen and synthetic liquid fuels from local waste.
