The first major countries such as the USA, Brazil, the UK, Saudi Arabia and the United Arab Emirates have joined a COP presidency initiative to increase global energy storage sixfold by 2030. They also want to build or modernize around 80 million kilometers of electricity grids by 2040. Fatih Birol, Chairman of the International Energy Agency (IEA), has welcomed the initiative. There are „plans for 3,000 gigawatts of renewable energies“, but these cannot be implemented because the „electricity grids do not have sufficient capacity“. The expansion of storage facilities is also important in order to make better use of flexible renewables, said Birol.
