Green hydrogen – energy storage
Green hydrogen may not be green. Blue hydrogen may be worse than other hydrogen colours if the methane gas has leaks. Depending on the source of methane, electricity the climate change emissions of hydrogen varies by source, electrolyser efficiency, carbon capture and storage efficiency. The life cycle analysis needs to be done on all hydrogen projects to see how they can reduce carbon emissions.

Hydrogen itself is not a direct greenhouse gas, as it does not absorb infrared radiation. However, evidence suggests it acts as an indirect greenhouse gas. When released, it extends methane’s atmospheric lifetime, increases tropospheric ozone, and adds stratospheric water vapor, all of which contribute to warming. Studies estimate its 100-year Global Warming Potential at 11.6 ± 2.8.

Hydrogen will be an essential fuel for the zero emissions economy says Dr Andrew Forrest in an interview on Cleaning Up Eps 210. With a 80% reduction in size, and an increase in efficiency to 96%, green hydrogen ammonia will move ships and enable green steel.

Geologic or gold hydrogen has potential to be part of the clean energy transition. Potential LCA and cost is low ($1kg), but there are technological and economic hurdles Co-production of helium with geologic hydrogen could be a key factor in making this technology commercially viable.
Research and development may determine the true potential of geologic hydrogen.
