Hamburg (ots) – have numerous wind gas electrolysers connected to the grid, to ensure a reliable power supply at high levels of renewable energy already in the next few years. According to a new study of the independent analysis institute Energy Brainpool commissioned by Greenpeace Energy needed by 2040 at least 14 gigawatts of installations. Wind gas electrolysers convert excess green electricity in renewable gas and make wind and solar power as in large amounts over long periods in the existing gas network can be stored. The current study is the first time a sound expansion path for even “power to gas” called Wind gas technology. “We must as soon as possible the course for a well-planned expansion of wind gas electrolysers to really create the energy transition and the CO2 targets for Germany too,” says Marcel Keiffenheim, Director Policy and Communications at the eco-energy provider Greenpeace Energy.
According to calculations of the Hamburg energy cooperative based on the new study should be installed from 2020 annually 100 megawatts (MW). The pace of expansion needed to 500 MW and 2030 rise annually from 2025 to 1000 MW in order to provide the necessary 2040 14 gigawatt can. “The technology is ready for the entry into production, with the falling asset prices quickly,” says Keiffenheim.
According to Energy Brainpool Wind gas is later than 2035 with then 74 percent renewables in the electricity sector system necessary. This means: Without electrolysers located could even with maximum use of other flexibility options like load shifting, battery or pumped storage not guarantee secure power supply. By 2050, 100 percent green energy, according to the analysis of 89 gigawatts needed to electrolyzers, in order to store the then resulting surplus electricity primarily from wind and sun as renewable gas. This also phase of up to three months with little wind and sun can be bridged by this energy is zurückverstromt flexible gas power plants again.
The investigation of Energy Brainpool also shows that a full supply of renewable energies in the interplay with wind gas and other flexibility options is significantly less expensive than the currently envisaged by the government version, according to which 20 percent of fossil fuel power plants to compensate for the fluctuations in wind and solar power: “the combination of short- and long-term flexibility options can be in we studied scenario 2050 save up to 17.6 billion euros per year. at the same time the share of renewables in the electricity system of 86 increases to 100 percent, “says study leader Thorsten Lenck.
According to a study commissioned by the environmental group Greenpeace on Tuesday of yesterday must Germany reach 100 percent renewable in the electricity sector even before the year 2030th Only in this way can contribute to the objective at the World Climate Summit in Paris aim to limit the increase of global warming as possible to 1.5 degrees Celsius instead of the previous maximum of 2 degrees. Correspondingly, also the wind-gas expansion would be accelerated. The technology is not only in the electricity sector is of central importance, power to gas is essential also for mobility, thermal industry, because even there the CO2 emissions must fall sharply to achieve the climate goals.
In the legal framework, however, wind gas is still not yet sufficiently anchored. Greenpeace Energy therefore calls on the federal government fair opportunities for the technology. So should electrolyzers running with ungefördertem wind power, in return must pay EEG apportionment. Moreover electrolysers could keep the power grid to renewable base stable. However, the market rules disabled hitherto non-discriminatory access. “These necessary improvements for a supply secure renewable electricity system it is not about subsidies,” says Marcel Keiffenheim Greenpeace Energy: “Rather We demand the dismantling absurd barriers that previously block the success of an important future technology.”
background information: the energy cooperative Greenpeace energy was founded by Greenpeace Germany in 1999 and still works on the ecological requirements of the environmental organization. Greenpeace Energy well supplied 111,000 customers with green electricity and more than 11,000 customers with the gas product proWindgas. The 100-percent subsidiary Planet Energy has built ten wind farms and three photovoltaic plants and is involved in three wind farms, the total capacity of all power plants is 78 megawatts. As a cooperative Greenpeace Energy is in sole possession of his 23,000 cooperative members and works not profit maximizing principle of
