Plans for using hydrogen to fight climate change are emerging across the San Joaquin Valley, with projects underway in western Fresno County, Pixley in Tulare County, and Orange Cove.
These initiatives showcase the potential of hydrogen to reduce greenhouse gases and support sustainable energy goals. However, a closer examination is needed to contextualize these developments within the broader hydrogen energy sector.
The Darden Clean Energy Project in western Fresno County stands out with its vast scale and ambitious goals. Covering 9,500 acres, the project includes a 3.1 million solar panel farm, a 1,150 MW green hydrogen plant, and a 4600 MWh battery storage facility. This integration of green technologies aims to produce 220 tons of hydrogen per day via solar-powered electrolysis, potentially serving as a zero-carbon transportation fuel.
While the project’s scale is impressive, it raises questions about feasibility and scalability. The use of an electrolyzer water treatment plant powered by solar energy is innovative, yet the challenges of maintaining stability and efficiency in hydrogen production remain significant. Compared to the existing largest hydrogen production plant, which produces only three tons per day, Darden’s proposed output is ambitious. The California Energy Commission’s (CEC) fast-track approval process may expedite the project’s timeline, but ensuring technical and economic viability will be crucial.
In Pixley, Tulare County, a proposed $120 million hydrogen plant faces legal challenges despite being allowed under the California Environmental Quality Act (CEQA) common sense exemption. A citizen group filed a lawsuit claiming the county did not adequately follow CEQA procedures, calling for a full impact report. This legal contention highlights the importance of thorough environmental assessments and community engagement in advancing hydrogen projects.
Chevron New Energies is developing a 5 MW hydrogen production project in Lost Hills, Kern County, using solar power and non-potable water from existing assets. This project aims to produce low-carbon electrolytic hydrogen, aligning with Chevron’s broader decarbonization goals. While the use of existing infrastructure and renewable energy sources is commendable, the project’s overall impact on carbon emissions and its integration with Chevron’s traditional oil operations warrant careful scrutiny.
SoCalGas plans to blend up to 5% hydrogen with natural gas for retail customers in Orange Cove, Fresno County. This 18-month demonstration project aims to develop standards for safe hydrogen blending, potentially reducing greenhouse gas emissions and improving air quality. The success of this pilot project could pave the way for broader adoption of hydrogen blending in natural gas systems, yet it must address safety concerns and technical challenges associated with such integrations.
