The project tests real-world effects across different pipeline materials and older infrastructure to understand impacts before broader rollout.

Opponents warn that hydrogen blending in Orange Cove could worsen health risks for residents with asthma or lung cancer, citing older appliances, potential rises in nitrogen oxides, leaks, and higher flammability from hydrogen.

Orange Cove, a predominantly Latino, low-income citrus town, has seen residents question transparency, health impacts, and whether the community will benefit from the pilot or bear the risks.

Residents say replacing old gas appliances poses financial and logistical barriers, raising concerns that the community could shoulder disproportionate risks without adequate protections or participation.

The 18-month, $64.3 million pilot would run on solar power to produce hydrogen and supply blended gas to about 10,000 residents and local businesses, funded by ratepayer money.

SoCalGas plans to implement safety protocols such as leak surveys, detection technology, backflow prevention, and defined emergency response plans to manage hydrogen blending risks.

The broader context includes California’s push for hydrogen blending as part of a clean-energy strategy, with national policy shifts and debates over financing and regulatory approvals from the California Public Utilities Commission.

Officials assert safety measures would be in place, including leak surveys, detection technologies, backflow prevention, and robust emergency response planning if the project proceeds.

Should the pilot move forward, safety measures would aim to contain hydrogen within the pilot area through rigorous leak surveys, detection, backflow prevention, and clear emergency procedures.

The proposal shifted from an initial UC Irvine site to Orange Cove due to mixed pipeline materials and a centralized gas feed; local leaders supported the move, while residents question whether adequate town halls and input will occur.

Experts call for more real-world testing and data on infrastructure and health impacts, with some backing phased testing and risk assessments, while others favor electrification as a safer route to emissions reductions.

SoCalGas proposes blending up to 5% hydrogen into Orange Cove natural gas as part of an 18-month pilot funded by ratepayers to curb pollution and test infrastructure compatibility.
