Jenbacher engines to bring fully renewable energy to California waste-to-hydrogen plant

Raven SR plans to use INNIO’s Jenbacher 60 Hz engines with a “Ready for H2” option to produce renewable energy in a continuous loop. The energy system, including Raven SR’s Steam/CO2 Reformation technology, will power and heat Raven SR’s S-Series hydrogen production facility at a sanitary landfill in Richmond, California.

  • Jenbacher engines to bring fully renewable energy to California waste-to-hydrogen plant

Using its proprietary, non-combustion, non-catalytic Steam/CO2 Reformation technology, Raven SR dependably produces a hydrogen-rich syngas, regardless of feedstock utilized. Raven SR is committed to adding value to local resources and communities while responsibly reducing greenhouse gases and achieving a low-carbon economy. By using modular systems and producing low air emissions, their systems can be located closer to customers and feedstock, creating local fuel from local waste for local mobility.

Up to 2,000

metric tons of hydrogen to be produced per year


INNIO’s Jenbacher engines and Raven SR’s Reformation technology will be fueled by landfill gas (LFG), which will provide power for the non-combustion process that converts waste to hydrogen. The hydrogen product will be resold to power fuel cells in heavy-duty trucks. The Raven SR process also will provide a hydrogen-rich residual fuel containing green hydrogen from the concentration process that will supplement the LFG, fueling the Jenbacher Ready-for-H2 engines to generate renewable power in a continuous loop.

We are proud to collaborate with Raven on this hydrogen industry first, which is a milestone in the interconnecting of transportation and industry with the power-producing sector. This project produces onsite renewable hydrogen from waste, uses a blend of hydrogen to generate energy to power operations, and provides renewable hydrogen for the transportation industry. This is a model example of how innovation can enable sector coupling, which will be critical on the global path to net zero.

Dr. Olaf Berlien, president and CEO of INNIO

Raven SR, headquartered in Wyoming, transforms biomass, mixed municipal solid waste, bio-solids, sewage, medical waste, and natural or biogas into renewable fuels.

Raven SR plans to bring its S-Series online in the first quarter of 2023 at the Republic Services West Contra Costa Sanitary Landfill. This project will initially process up to 99.9 tons of organic waste per day and produce up to 2,000 metric tons per year of hydrogen.

INNIO is able to meet our delivery schedule and provide engines that are compliant with emissions requirements for a blend of CO2, methane, and hydrogen. The Jenbacher engines are a very important element for us to realize our objective of producing renewable hydrogen with our non-combustion Steam/CO2 Reformation process, independent of the grid. Raven’s success in the increasing energy and electricity crisis requires that we generate autonomous power on site. To succeed in the energy transition, collaboration among best-in-class engineering around the world is required. We are grateful to work with INNIO on this advanced, self-contained renewable-energy design.

Matt Murdock, CEO of Raven SR

The collaboration with
Raven SR’s technology

offers a strong renewable hydrogen alternative to electrolysis, using
less electricity and no need for fresh water. INNIO’s Jenbacher engines
will allow the Raven SR facility to generate a significant amount of its
own electricity, reducing demand on California’s electrical grid.
