FirstElement Fuel (FEF) has urged the California Energy Commission to continue funding light-duty hydrogen refuelling stations to avoid consolidating supply chains for heavy-duty hydrogen mobility. The commission's draft plans suggest a shift towards medium- and heavy-duty hydrogen stations, potentially neglecting light-duty infrastructure. FEF stresses that supporting light-duty stations is crucial for creating supply chains and economies of scale necessary for heavy-duty infrastructure. The California Energy Commission aims to spend at least $15m annually on hydrogen infrastructure until 2030 but is considering focusing on medium- and heavy-duty stations in the upcoming years. FEF argues that the behaviors and needs of medium-duty vehicles differ from heavy-duty vehicles, requiring specific infrastructure at neighborhood fuelling stations. The call for continued funding for light-duty stations is supported by the idea of upgrading existing stations to accommodate various vehicle classes effectively. Overall, the article highlights the importance of maintaining a diverse range of hydrogen refuelling infrastructure to support the growth of clean transportation technologies and reduce greenhouse gas emissions in California.
