As the share of fluctuating, decentral supplies of energy such as wind and solar power increases, major new challenges to our energy system present themselves. Pioneering technologies for storing electricity and heat may well play a key part in the sustainable, secure energy supply system of the future. In Austria research into a number of new approaches and strategies for storing electricity and heat from renewable sources of energy is currently in progress, including demonstration projects to test them under real-life conditions.
