Comparing the costs of green hydrogen and blue hydrogen reveals significant differences, primarily due to their production methods and technology.
Green Hydrogen
- Production Method: Green hydrogen is produced by electrolysis using renewable energy sources like solar or wind power to split water into hydrogen and oxygen.
- Cost: The cost of green hydrogen currently ranges from €3 to €7 per kilogram (approximately $3.30 to $7.70 USD), depending on the cost of renewable energy and the efficiency of electrolyzers. There are estimates that these costs could decrease below €2 per kilogram as technology advances and renewable energy becomes cheaper.
Blue Hydrogen
- Production Method: Blue hydrogen is derived from natural gas through steam methane reforming (SMR) but incorporates carbon capture and storage (CCS) technologies.
- Cost: Blue hydrogen typically costs between €1.50 and €3 per kilogram, making it cheaper than green hydrogen but more expensive than grey hydrogen.
In summary, green hydrogen is currently more expensive than blue hydrogen due to the high costs associated with renewable energy and electrolysis technology. However, as green hydrogen production becomes more efficient and renewable energy costs decrease, it is anticipated to become more competitive.
