Germany needs natural gas in the energy structure, and its development as a so-called "green" market hydrogen is based on renewable energy, said Winters' boss. Germany hopes to develop large-scale green hydrogen energy by using wind and solar energy to produce synthetic fuels for the industrial, energy and transportation sectors, and has launched a hydrogen energy strategy that will cost 9 billion euros (10.64 billion U.S. dollars) by 2030.

Mario Mehren, CEO of natural gas and oil producer Wintershall, said: “As long as the supply and price of green hydrogen are not attractive enough, we also need the hydrogen in natural gas to quickly build the market.” I firmly believe that in the long run, green hydrogen will benefit from a mature market." Mellen said at the annual meeting of the electricity and natural gas lobby group BDEW, implying that gas-derived hydrogen will help it reach that stage.

Green hydrogen comes from renewable energy sources, which may include offshore wind floating electrolysis plants. The hydrogen extracted from natural gas is called "gray" hydrogen. The question of how to best achieve Germany's hydrogen energy goals has been plagued by time and the use of different hydrogen "colors". Some environmental lobby groups want green hydrogen or don't want anything, and energy companies are offering interim steps plans, including carbon capture and storage (CCS) plans.

CCS enables industrial emissions to be captured and stored in depleted subsea hydrocarbon fields, where Norway, Denmark and the Netherlands are far ahead. The major German political parties in the race support the hydrogen energy market. Christian Bruch, CEO of Siemens Energy, said that any new government needs to simplify hydrogen regulations and fund investments in factories and their operations. Siemens' goal is to make all of its gas turbines capable of long-term hydrogen operation by making them "hydrogen-ready" now.

But he said that natural gas power generation has half the carbon emissions of coal, and it will take several years of operation, especially in overseas markets. But lobbying groups Deutsche Umwelthilfe (DUH) and Urgewalt criticized the German government for allegedly supporting fossil fuels, arguing that "the harmful effects of natural gas on the climate have been scientifically proven."Editor/XuNing
