About Us

Renewable energy while enriching farms, forests, and the environment

Using innovative and leading technologies, Yosemite Clean Energy transforms farm and forest wood waste into renewable, zero-emissions hydrogen for the transportation sector.

The Yosemite Clean Energy Advantage

Lower capital costs

Dual-fluidized bed gasification is a proven technology that reduces the need for an Air Separation unit to provide oxygen, resulting in higher system efficiency.

Lower operating costs

No tonnage oxygen is required. No outside energy, like Natural Gas, is used to run the system.

Feedstock flexibility

No complex feedstock preparation required and is relatively feedstock agnostic.

Scalable

Current scales from 10–100 MWt, and potentially up to 200 MWt

Multi-revenue streams

Hydrogen, RNG, Credits and Heat Sales

Low carbon intensity

Low CI, and with CCS the renewable hydrogen, can be a negative carbon fuel

Current Yosemite Projects

Kettleman City, California

Hydrogen Plant #1, located in Kettleman City, is currently under front end load engineering and design phase two.

This project will produce an estimated 14.5 MT hydrogen per day to Interstate-5 trucking and passenger vehicles. Our Farmer Co-op business model makes the wood suppliers the owners of this plant. We are estimated to utilize approximately 100,000 Bone Dry Tons of biomass per year.

Site plans are underway. Discussions with farmers in Fresno and Kings Counties are welcomed.

Groundbreaking, December 2020

Auberry, California

Auberry, a former lumber town in California, was hammered with the Western Pine Beetle epidemic that has ravaged the Sierra National Forest over the past five years. The pest has killed over 140 million pine trees in the Sierras and more than 30 million trees in the Auberry region. 

Yosemite Clean Energy has been working with the Sierra Resource Conservation District, an organization stewarding the forests in the area. SRCD is a partner and supports the development of the Aubery plant. In addition to hydrogen production, this site will include a small Fischer-Tropsch demonstration system to provide FT liquids for Bio-Jet fuel production. The pre-engineering phase is slated to begin in 2020.

Groundbreaking, September 2021

Grass Valley, California

For the past several years, Yosemite Clean Energy has been working with the Nevada County Biomass Task Force to develop a 10 MT hydrogen biomass plant near Grass Valley, California. 

We have been collaborating with local and state agencies to put this project into the detailed engineering phase by late 2020.

Groundbreaking, April 2021

Yosemite Clean Energy LLC will be project developer of all three plant facilities, and through our consortium, we will design, build, and commission the plants by using the dual-bed gasification technology from Repotec (Aichernig Engineering & TU Wien)

Scale of Projects

Green  hydrogen — processing approximately  50,000–100,000 bone dry tons of biomass per year

Producing 14,500 kg/day of hydrogen

1 plant will supply = 250 fuel cell HDV

Or up to 450–500 fuel-cell buses per day

FLUOR

Fluor Enterprises (FLR), is a global Fortune 500 company and has been engaged by Yosemite as Owner’s Engineer and will be the lead for Yosemite’s project engineering oversite and support for project success. Fluor is a global leader in gasification know-how. They have expertise in a broad cross-section of supporting technologies, including gas treating, sulfur recovery, carbon dioxide compression, combined-cycle power generation, and product synthesis. The integration of these technologies into efficient IGCC plants and energy complexes is one of Fluor’s key strengths.

Fluor has expertise and depth in gasification and supporting technologies with a comprehensive FEED, engineering, procurement, construction, and maintenance services portfolio. They have an impressive proven track record executing major energy projects. Fluor will work with our technology providers and EPCs to guide Yosemite Clean to develop our plants.

Repotec

REPOTEC (Aichernig Engineering- GmbH), led by principal Christian Aichernig, has been developing commercial applications of the dual-fluidized bed gasification technology for over 20 years. The company has successfully commissioned over ten projects globally, and Yosemite Clean has the exclusive rights to develop Biomass projects in the USA under a licensing agreement. REPOTEC has significant knowledge in the sophisticated application of biomass gasification and is experts in dual-bed gasifiers and syngas cleaning. With the experience and expertise of REPOTEC, Yosemite Clean Energy will be able to produce Green Hydrogen, RNG and possible Heat and Power additional product streams. 

With a proven track record and a simpler and more effective and efficient design and total inputs and outputs, using their experience for developing the Yosemite project will be one of the keys to success.

MMR Power Solutions, LLC

MMR Power Solutions is one of the key companies to provide power and operate distributed power for the Yosemite Clean Bioenergy fuels plants. MMR will also be a partner for plant operations and maintenance. MMR has an in-house team of an experienced team of estimators, engineers, project managers, technicians, construction, and maintenance personnel. This partnership ultimately alleviates the need to rely on the utility alone for crucial energy supply, reducing the risk of market exposure by having more internal control over vital energy supply. From gas engine and turbine plants to renewable power generation facilities—and hybrid power plants using a combination of technologies, including energy storage—MMR has the technical expertise, workforce, and resources to support Yosemite Clean Energy’s project goals and objectives.
