Hydrogen severance tax.

HB 161 would impose a severance tax on hydrogen production in Wyoming, specifically targeting hydrogen separated from ground water. It sets two tax rates: 3% for hydrogen from "by-product water" (as defined in existing law) and 6% for all other hydrogen production. The tax would be calculated based on the fair market value of the hydrogen, similar to how natural gas is taxed, and collected by the state department. The bill, which died in committee in March 2025, would have taken effect July 1, 2025, but is not currently law.
