Energy storage

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.

New name, new style: The previously named HH Ferries Group, which operates the busy ferry route between the Danish and Swedish coastal towns of Helsingør and Helsingborg has not only changed its name to ForSea Ferries to reflect its environmental strategy, but has also officially launched its two long-awaited, solely battery-powered passenger ferries, which are the largest of their kind.

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.

The scientists behind the technology believe that using biological material from mould to manufacture batteries will revolutionise electricity storage.

An exhilarating week of energy events in the Nordic cities of Copenhagen and Malmo drew to a close last Friday. Known as Nordic Clean Energy Week, the event gathered an influential and broad group of actors from the energy sphere, ranging from energy ministers and researchers from G20 economies, to companies and investors with the common goal of accelerating the global transition to a world powered by renewables.
