Green hydrogen costs fall, but not quite enough
The cost of electrolysers have fallen sharply over the last decade, but power-to-gas technologies will not be competitive with fossil-based hydrogen before 2030, panelists told a webinar hosted by CMS law firm.
One key barrier for renewable hydrogen development is the relatively high start-up costs compared with other technologies. This means there is a need for government subsidies to get projects off the ground.
Bernt Elsner, a Vienna-based partner with CMS, told the webinar that the estimated costs for renewable hydrogen projects is €2.5-5.5/kg, compared with €2/kg for fossil-based hydrogen with carbon capture and storage (CCS) and €1.5/kg for fossil-based hydrogen without CCS. Fossil-based hydrogen is hydrogen produced by natural gas and, to a lesser extent, coal and is the technology that dominates the hydrogen market today.
However, the cost of electrolysers has been reduced by 60% in the last ten years and a further 50% cost reduction is expected by 2030. Regions with relatively cheap electricity produced by wind and solar are expected to be able to compete with fossil hydrogen by 2030, said Elsner.
“This means that until 2030 state subsidies will be necessary to promote clean hydrogen,” he said. Elsner noted that a review of the EU’s state aid guidelines for energy and climate was expected in 2021. The guidelines are expected to help clarify which type of national subsidies for hydrogen projects that will qualify for state aid approval by Brussels.
Moreover, the EU is expected to scale up its funding for clean hydrogen projects over the coming years as stipulated in its hydrogen strategy launched in July. Renewable hydrogen produced by wind and solar is a priority. The roadmap calls for 40 GW of electrolysis capacity in Europe by 2030, and a further 40 GW in Europe’s “neighbourhood” such as North Africa and the Ukraine.
