Energy storage solutions are an important part of the clean energy transition, given that renewables don't have the capabilities to produce energy continuously. ESG Today writes that 2021-founded Field develops, makes and operates battery storage systems, which are charged from renewables when demand is low. When demand increases and green power sources may not have the capacity to fulfill the network's needs, batteries start deploying their stored power.

Field already has a few on-grid storage projects in the UK and Western Europe, amounting to 4.5GWh of total capacity. The company is currently operating its first energy storage system in Greater Manchester, with a capacity of 20MWh.

Amit Gudka, Field founder and CEO said that "we will not be able to meet net zero targets without significant investment in new energy infrastructure. Battery storage is a critical part of that infrastructure. The more we can build, the more effective mass-usage of wind and solar power will become."

Gravitational batteries are another way we can store renewable-generated electricity. Gravitational batteries operate sort of like an elevator in the way that weights are lifted by special cranes and slowly lowered to generate electricity, when it is needed. We could install these systems in old mine shafts, for example, which aren't used anymore and could have a great potential for energy storage purposes.
