The increase in the global deployment of wind and solar generation is creating a new challenge for the energy industry: how to manage increased volatility in electricity generation. Electricity storage can help manage this volatility and create a stable and flexible power system as it allows the balance between supply and demand to be maintained at all times.
Of the many storage technologies, electrochemical storage has long been the focus of a great deal of research, given its attractive features and potential range of applications. Electrochemical storage systems fall into two groups: solid state batteries and flow batteries. Solid state batteries are known as ‘closed systems’ (where the relationship between power (kW) and energy (kWh) is fixed) and the energy is stored as an electrode. These include conventional lead acid batteries which are unsuitable for large applications and lithium-ion batteries which benefit from high efficiency and energy density but are limited by their reduced storage time, shorter lives and on-going safety concerns.Read more…
