Study Notes

Green Hydrogen: Advantages, Classification, Challenges, and Applications

Hydrogen is a clean energy source that emits only water when used.
Green hydrogen is produced by splitting water using electrolysis powered by renewable energy sources like wind or solar.
Grey hydrogen is produced by splitting natural gas into hydrogen and CO2, but the CO2 is not captured, while blue hydrogen is produced through the same process, and the CO2 is captured and stored.
Green hydrogen has significantly lower carbon emissions than grey hydrogen, which makes up the bulk of the hydrogen market.
Green hydrogen production is less than 0.1% of total hydrogen production but can help decarbonize hard-to-electrify sectors such as steel and cement.
The flammability and lightness of hydrogen require proper handling, but its low concentration has similar flammability potential as other fuels.
Transporting hydrogen is challenging due to its low density, requiring compression or liquefaction, and transport through pipelines, tanker trucks, tube trailers, rail, or barge.
Green hydrogen is renewable, storable, and transportable, making it a key component of the energy transition towards carbon neutrality.
Electrolysis is a promising option for carbon-free hydrogen production from renewable and nuclear resources, using electricity to split water into hydrogen and oxygen.
Electrolyzers range in size from small, appliance-size equipment to large-scale, central production facilities.
Applications for green hydrogen include energy storage, fuel-cell vehicles, and decarbonizing residential and commercial heating systems.
Fuel-cell vehicles remain a challenge due to the cost-competitiveness of battery-powered cars, while mixing green hydrogen into natural gas can reduce carbon content in places where natural gas prices are relatively high.
