Hydrogen energy is produced through the electrolysis of water, a process that requires energy input from either renewable or non-renewable energy sources. Only green hydrogen, which makes up less than 1% of hydrogen today, uses renewable energy for this process. The use of hydrogen for heating and cooking in homes and buildings is considered a false solutions because it is not nearly as efficient as electrification and hydrogen leakage is a safety hazard.
