Strategic Partners


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.
