Storage of Energy by Batteries or other Storage Solutions / Energy from Sun and Wind

19 Oct 2018 Backstage information for more clarity from an insider: The problem of wind and sun plants in central European countries is, that these plants only produce a lot of energy if wind blows or sun shines. Therefore, other power plants must be present to jump in if wind does not blow or sun does not shine. Wind energy also requires many power lines to dissipate the huge amount of electricity produced – when wind is blowing. At the moment wind turbines even have to be switched off because the power grids are overloaded. The problem could be solved if the current of wind and sun could be stored – and that at reasonable costs. In Norway, surplus energy pumps water into reservoirs high up in the mountains and then uses the water flowing down to produce energy – at the time when energy is needed. These water pump plants however can be built at few places and are not free of damaging the environment. Since years researchers seek to develop usable batteries or develop other power storage solutions as hydrogen (see fuel cell car). Or gases in power-to-gas-technology.
