Submission Statement: “Hydrogen (H₂) is expected to play a crucial role in reducing greenhouse gas emissions. However, hydrogen losses to the atmosphere impact atmospheric chemistry, including positive feedback on methane (CH4), the second most important greenhouse gas.”

With more and more governments subsidizing hydrogen production, we need to really be certain it won't cause more problems than it will solve.
