Comments to the Dept. of Treasury on Credits for Hydrogen Production

To date, climate change mitigation policy has typically been carbon-centric and focused solely on reducing carbon emissions. We urge the 45(v) tax credit proposed rule to move away from carbon centrism by addressing EJ issues that include limiting the emissions of GHG co-pollutants in general as much as possible.

A carbon centric approach and focus on solely using the lifecycle GHG emissions rate of hydrogen production as the metric to determine whether the hydrogen produced is “clean”, is a significant EJ concern. This approach ignores the emissions of GHG co-pollutants along the life cycle of not just hydrogen production but storage, delivery and end uses (such as the burning of hydrogen-blended natural gas at power plants3). Additionally, when a life cycle GHG emissions rate is the sole metric to determine whether the hydrogen produced is clean, a myriad of environmental and health impacts along the hydrogen production chain remain insufficiently addressed.
