The SoHyCal project in Fresno, California, represents a significant milestone in the green energy sector by being the largest green hydrogen production site in North America. This pioneering plant, owned by H2B2 Electrolysis Technologies, started operations on November 1, 2023, with the goal of producing 3 tons of green hydrogen daily through PEM electrolysis technology. The plant operates in two phases: currently, it utilizes biogas for production, and a future phase will transition to solar power for increased capacity by 2025. SoHyCal's production aligns with California's clean energy objectives and aims to supply carbon-less hydrogen to meet the demand for clean fuel in the transport sector, contributing to lower CO2 emissions. The success of SoHyCal was made possible through collaboration with stakeholders like the Fresno County Economic Development Corporation, ensuring the project's compliance with regulations and securing necessary resources. The project's future looks promising, with plans to expand production capacities and replicate the system in other regions to boost the hydrogen economy. The green hydrogen produced at SoHyCal signifies a positive step towards a sustainable energy future and showcases the potential for hydrogen as a key player in the transition to cleaner energy sources.
