Not clear what is meant here. Does ethanol from corn count? Methane from waste dumps? Gray hydrogen? Wood pellets? Ammonia?

Electricity from unclear source?

Human ingenuity is infinite. It is not enough to enact simple rules, people will just produce electricity with hydrogen and claim it green if it will make them profit. If it will help them evade carbon tax. Nevermind that hydrogen came from some extremely polluting process involving damaging our planet atmosphere and everyone's health.
