What is the biggest hurdle to affordable green hydrogen?Posted by Santiago Bresani on October 11, 2022 at 06:56
The road to green hydrogen, nonetheless affordable green hydrogen seems to be a very long one. I wonder when people expect we will have >5EUR/kg green hydrogen available in Europe?

I believe that the cost related to green electricity production is a major factor that affects the total cost of hydrogen production. But on the brighter side, companies are working to incorporate a hybrid offshore hydrogen production system that will certainly help in the cost reduction of green hydrogen.
But there are several factors as well. The slow increase in demand for hydrogen could also be a reason as oil is still a major source of energy production in the world. Last but not least energy security has also had a certain influence on the cost of green hydrogen production.
I hope this answers your question.

Cost of green electricity is the leading barrier to production of large amounts of green hydrogen because most people believe electrolysis is the only way to produce green hydrogen. If you can use curtailed energy from a renewable source, there is a good chance you can produce cheap green hydrogen. Most renewable sources are not near ideal locations for production or distribution so it can be a challenge. Green hydrogen can be produced from pyrolysis also. This process has not taken off because of the difficulty of producers to secure consistent supply of feedstock and also because currently few investors are interested in funding waste to energy projects.

Hi Santiago, I recall a statement from a Siemens manager who is building off-shore wind parks in the Baltic see that they expect the price of green hydrogen to come down to 5 EUR already in 2025 in Europe. Such a statement however was made last year (i.e. before the energy crisis we are currently facing)
