Plans for using hydrogen to fight climate change are sprouting all over the San Joaquin Valley this summer. Projects are in the works in western Fresno County, in Pixley in Tulare County and in Orange Cove where SoCal Gas will blend 5% hydrogen with natural gas for retail customers reducing overall greenhouse gases.
When hydrogen is injected into a fuel cell, hydrogen generates electricity but emits only heat and harmless water vapor and has great potential to cut global carbon emissions and keep toxic pollutants out. Experts say hydrogen could make the biggest difference in sectors now mostly powered by fossil fuels — trucking, shipping and aviation.
In the westside of the Valley, the Darden Clean Energy Project would cover 9,500 acres owned by Westland Water District and include a trifecta of green technologies including a 3.1 million solar panel farm, a 1,150MW green hydrogen plant and a 4600MWE hour battery storage plant.
An electrolyzer water treatment plant would be powered by solar power capable of producing 220 tons of gaseous hydrogen per day that could be used as zero carbon transportation fuel. To bring electricity to the grid the sprawling energy farm would be connected to a 15 mile transmission line to a PG&E substation near Highway 5.
Instead of seeking approval through Fresno County, the massive project is going direct to the California Energy Commission (CEC) for final permitting under a new provision approved by the legislature in 2022 called opt-in, the first in the state to do so.
Largest in the world
The Darden Clean Energy Project, which more than rivals the largest solar battery storage combination in the world, is located in Kern County at Edwards Air Force Base and is said to be about 4,000 acres. It houses 1.9 million solar panels and generates 3287MWh for the battery storage facility. The Kern County project also does not include a hydrogen manufacturing component.
In terms of the hydrogen plant at the Darden site, the capacity at 220 tons of hydrogen a day compares to just three tons a day at the largest existing hydrogen production plant on 324 acres also in Fresno County that started up last year led by a Spanish firm.
The CEC must find that Darden has submitted a complete application and then has 270 days to approve the project, which is considered a fast-track process in order to get more battery storage in California online sooner.
Hydrogen’s flexibility as a fuel source including for transportation, industrial, and power generation sectors and its ability to be stored is helped by new tax incentives under the Inflation Reduction Act. Producing only water as a byproduct hydrogen can be injected into the natural gas distribution system managed by utilities like SoCal Gas and PG&E. Add the synergy of combining solar power generation and hydrogen manufacturing – the process is given a big boost by the power from the sun typically on-site.
Lawsuit in Tulare County
In Pixley in Tulare County, another company is proposing to build a 1.2 million square-foot 28-acre hydrogen plant that will manufacture, store and distribute pressurized liquid hydrogen fuel for trucks and include 114 acres of solar power generation. The location of the $120 million plant is at the southwest corner of Avenue 120 and Road 120 near Highway 99.
Last summer the County of Tulare determined their project was allowed by right under the CEQA common sense exemption since the property was already located in a manufacturing zone. In March 2024 a citizen group with members from Pixley filed a lawsuit objecting that the county had not properly followed CEQA rules and should require a full impact report.
Oil company wants in
Also this spring, Chevron New Energies, a division of Chevron U.S.A. Inc., announced it is developing a 5-megawatt hydrogen production project in Lost Hills.
The project aims to create lower carbon energy by utilizing solar power, land, and non-potable produced water from Chevron’s existing assets at the Lost Hills Oil Field in Kern County. This low carbon intensity electrolytic hydrogen will be produced through electrolysis, which is the process of using electricity to split water into hydrogen and oxygen.
“Hydrogen can play a vital role in our journey toward a lower carbon future,” said Austin Knight, vice president for hydrogen at Chevron New Energies.
Blending hydrogen
Use of hydrogen will hit the retail market in Orange Cove says SoCalGas.
At the direction of the California Public Utilities Commission, SoCalGas is proposing a local demonstration project that could safely blend up to 5% clean, renewable hydrogen into the natural gas system serving approximately 10,000 residents, along with commercial customers in the City of Orange Cove, in Fresno County.
SoCalGas is proposing an 18-month demonstration project that will blend clean, renewable hydrogen serving residents and businesses. This project would offer a real-world environment to better understand how clean hydrogen and natural gas can be safely delivered to customers in the future. This is part of a broader effort by California and utilities to develop a standard for safe hydrogen blending, which could reduce greenhouse gas emissions and improve air quality, says the company.
