Power-to-gas most cost efficient way to reach long-term climate targets – study

Employing power-to-gas technologies (PtG) help to achieve Germany’s 2050 climate targets in the most cost-efficient way, writes the German Association of Gas and Water (DVGW) in a press release. The association commissioned a meta-analysis by consultancy Ecofys, which examines ten studies and papers on the topic. The different scenarios all show that sector coupling technologies such as PtG will be necessary, but differ on when and in what form, writes Ecofys. The consultancy says that costs to establish and operate a PtG infrastructure vary a lot in the different studies. It adds that the biggest cost-saving potential of PtG is in the building sector. “In order to place the urgently needed sector coupling on a stable and affordable foundation, we now need corresponding technology and market launch programmes," said Timm Kehler, CEO of gas industry lobby organisation Zukunft ERDGAS, at the study presentation.
