Energy storage systems – the key to the energy revolution and global climate protection
Climate change is a reality. Every nation on our planet is affected by weather extremes, a rise in sea level or a scarcity of drinking water. Only joint action – which, after years of dispute, was finally agreed upon at the historic 2015 UN Climate Change Conference in Paris – and a global move to renewable energy resources can limit the consequences of global warming. Highly efficient energy storage systems are required, however, in order to use solar, wind and hydropower non-stop and all year round.
Up to now, the focus has tended to be on the direct storage of electricity by means of expensive batteries. However, batteries have only a short service life, are expensive due to their complex chemistry and can only be recycled with great difficulty. Yet energy can also be stored very efficiently as heat. When taken out of storage, this heat can not only be used for heating spaces, but can also be converted back to electricity at any time. In addition, thermal storage systems – such as those developed to marketability by EnergyNest – beat all battery options on a number of relevant points: they are cheaper and easier to produce, are longer lasting and environmentally friendly as well. Therefore, it is only logical to exploit the immense potential of thermal storage substantially more in the future.
