German Finance Minister Christian Lindner has expressed support for hydrogen in all colors as EU countries discuss hydrogen's potential role in decarbonizing the economy and reducing dependence on imported fossil fuels. The debate over whether to focus on hydrogen made using renewable energy or low-carbon hydrogen made using nuclear energy has delayed negotiations on new EU renewable energy targets and threatened multibillion-euro hydrogen pipelines. France, which relies heavily on nuclear power generation, is leading a campaign to boost nuclear energy's contribution to reducing carbon dioxide emissions, while Germany and Spain say it risks undercutting efforts to expand renewable energy on a large scale. Hydrogen produced from renewable sources is preferable in the long run, but in the short term, the EU needs to create a market structure that provides a reliable supply at an affordable price, Lindner said. The issue is not only divided across Europe, but also within Germany, which opposes nuclear energy.
