Blue hydrogen’s eligibility for production tax credits under the US’ Inflation Reduction Act (IRA) should be project-specific and location-dependent to ensure true emissions reduction, according to a new study.
That’s because “location matters” in determining the lifecycle greenhouse gas (GHG) emissions intensity of blue hydrogen, the study published in the Nature Energy journal said.
“Recent evidence from direct measurements across the oil and gas supply chain demonstrates the large spatio-temporal variation in methane emissions,” it said, which directly impacts blue hydrogen’s emissions lifecycle.
