As California Hydrogen Hubs Receive Billions, Public Health Concerns Grow | KQED
Briefly

Hydrogen can power trucks and airplanes without emitting harmful gases, aiding in reducing carbon footprints for heavy industries.
Despite producing no carbon emissions, extracting hydrogen from water or methane can be complex and costly, potentially prolonging climate pollution if reliant on fossil fuels.
Clean hydrogen production is crucial, as blending hydrogen with methane and burning it can still produce toxic byproducts contributing to lung-irritating smog.
The U.S. government's significant financial investments in hydrogen energy through grants, tax credits, and hub systems are part of a risky and ambitious national initiative.
