Energy storage

Three electric cars at Roskilde Festival’s Food Court ensure ample electricity to cope with peak loads without using generators.

Electric power has tremendous potential, given the possibility to use it as a fuel source in transport, heating and industry. It can play a central role in reducing the planet’s CO2 emissions, thereby achieving the objectives of the Paris Agreement. These are the key messages of the Renewable Energy Outlook 2019, that was released in Copenhagen this week.

In the future, buildings may function as valuable heat storage units in a sustainable energy system.

A research project at the Niels Bohr Institute will look into superconductors that can help ensure big energy savings by e.g. reducing the energy loss during transportation through cables.

The circular economy entails reusing and reutilising resources. A new pilot plant is to be established that will store surplus energy from wind turbines and transform it into a sustainable, green ammonia product. Doing so will also help reduce CO2 emissions.

At Aarhus University, Denmark, researchers and Danish companies have developed a pilot plant that can convert CO₂ into methane gas. In the future, greenhouse gasses can turn out to be a valuable resource, according to the researchers.
