Desperately seeking energy
Electricity from wind and solar power more effectively
Lithium batteries are not only the key component for the electrification of truck traffic, they also open up new possibilities for energy from wind and solar power more effectively. The idea of the researchers: small feeders in remote areas, for example, homeowners with solar panels on the roof, in the future may place on sunny days, excess electricity in today’s conventional lead-acid batteries stored in lithium batteries.
Wind
As energy could then use the batteries in electric cars. There is too little power, network access back to the stored energy in the batteries. This allows the electricity grid stabilized with the help of hybrid cars.
Wind and solar power will be supplied on demand
“This is one of many ways to save energy, which we run through the project ‘energy web’” explains Dr. Christian Doetsch, head of the energy division at the Fraunhofer Institute for Environmental, Safety and Energy UMSICHT in Oberhausen of the Fraunhofer-future theme coordinated. “Our goal is to make the delivery of wind and solar power as planned, as the energy from conventional power plants.”
Windfarm
Because scientists from seven Fraunhofer Institutes. The challenge: power from the sun and wind flow is very irregular. On windy days, wind turbines produce up to 20,000 megawatts of electricity - equivalent to the capacity of all German nuclear power plants. But is not always the amount of energy needed. In 2006, approximately 15 percent of the electricity generated by wind power plants could not be fed, and thus went for the consumption lost.
Effective caching
Photovoltaics
If by 2050 about half of total energy demand in Germany should be covered by renewable energies, the need for caching of generated energy efficient technologies are developed. The only way to continue to avoid that wasted energy is lost.
A similar situation arises with solar power. Dine on sunny days, solar energy systems into the public grid a - not on gloomy rainy days. However, power generation and consumption must comply at all times. To avoid gaps in coverage that fit the suppliers in the electricity generation and ready back-up service.
