As can be viewed from previous blogs, we keep a close eye on the Hydrogen developments worldwide.
The International Renewable Energy Agency (IRENA) shows on their website an extremely useful overview of the possibilities and applications of Green Hydrogen. Furthermore it makes a good distinction between Fossil fuel based grey hydrogen, blue hydrogen, turquoise hydrogen and green hydrogen. Costs developments are elaborated and show the full potential in the areas of energy transition. For further detail, please click here ….
Notes: the various types of Hydrogen are nicely shown by IRENA on their website:
- Fossil fuel based grey hydrogen (source = methane of coal; process = steam methane reforming (SMR) or gasification).
- Blue hydrogen (source = methane or coal; process = SMR or gasification with carbon capture).
- Turquoise hydrogen (source = methane; process = pyrolysis).
- Green hydrogen (source = renewable electricity (e.g. offshore wind energy and solar energy); process = electrolysis).
- Majority of hydrogen produced today is grey hydrogen, but the potential for green hydrogen is huge.
