Standalone battery energy storage can potentially offer better value to the US electricity system than pairing batteries directly with solar or wind generation, but the pros and cons of each approach vary greatly from project to project.
The UK needs “robust energy storage technologies and clear strategies for implementing them,” to accelerate the transition towards decarbonisation, the lead author of a new roadmap detailing the role of energy storage technologies in the country over the next 10-15 years has said.
The value of energy storage increases with growing shares of renewable energy on the grid, but the availability and cost of storage will determine how successful decarbonisation with renewables can be.
Northern Ireland’s Queens University Belfast (QUB) has found that battery-based energy storage can provide inertial response for system reliability much more efficiently, at a lower cost and with substantially reduced emissions than thermal generation. Dr Marek Kubic at Fluence, which is working with QUB, explains.
The UK’s Solar Trade Association (STA) has refuted claims made in a recent report that a residential solar array in combination with an energy storage system was not “economically viable”, calling it flawed and lacking in detail.
