Expenses for electricity significantly influence the generation costs of green hydrogen. A large part of this, the EEG surcharge, is being abandoned as of 01/07/2022. This removes yet another barrier to the ramping-up of the hydrogen economy in Germany. In 2030, Germany hopes to achieve an electrolysis capacity of 10 GW and aims to become the world leader in this field as a result of joint European projects and joint investments in hydrogen technology. A prerequisite for a ramp-up of hydrogen technologies and the export of these technologies is resilient and sustainable domestic generation of hydrogen. The prices for electrolyzers, stacks and complete systems have fallen by 20% in the last 24 months due to scaling of the production process. Currently, most electrolyzers are series-produced. In 2030, potentially even 2025, green hydrogen will be able to compete with grey hydrogen from a price perspective. In addition to capital costs for the electrolyzer, the costs for purchasing electricity represent the highest share of the overall costs for the electrochemical generation of green hydrogen.
