Germany’s latest ‘net zero’ plan involves storing carbon dioxide underground beneath the sea

Europe’s biggest economy is making good progress with expanding renewable energy sources and usage, but a solution is needed for the carbon dioxide emitted by some sectors such as the cement industry that are “hard to abate,” said Robert Habeck, who is also the economy and climate minister.

Germany, which is home to many energy-intensive industries, aims to cut its emissions to “net zero” by 2045.

Habeck’s proposed “carbon management strategy,” which still needs to be turned into detailed legislation, foresees enabling the transport of carbon dioxide and its storage under the sea in Germany’s exclusive economic zone, except in marine conservation areas. It doesn’t foresee allowing storage sites on land, but Habeck said that could be considered later if German state governments approve.

Opponents maintain that so-called carbon capture and storage is unproven at scale and has been less effective than alternatives such as solar and wind at decarbonizing the energy sector.

Habeck, a member of the environmentalist Green party, recalled opposition to carbon storage when it was discussed in the 2000s. But he said “the technology has been developed further … and from my point of view it is mature and safe,” and that it is now being used elsewhere, not just in research projects.

Neighboring Denmark last year launched an ambitious project that aims to bury vast amounts of carbon dioxide beneath the North Sea.

“Time has run out,” Habeck said at a news conference in Berlin. “In the 2000s, you could perhaps say, ‘let’s wait and see what might happen’; today we see that we haven’t found any technological solution for cement and other areas that ensures climate…
