By 2023, the UK’s energy storage capacity could grow more than 10 times, attracting up to $20 billion in investments for battery storage systems. This would mean the UK will have enough energy reserves to power 18 million households for a year. However, actual deployment faces challenges like grid connection issues and supply chain dependencies.
Industry insiders believe the long grid connection approval periods severely restrict energy storage projects. The UK needs to strengthen domestic battery manufacturing to reduce import reliance. Additionally, pumped hydro and other long-duration storage urgently require policy guidance to advance commercialization. Looking ahead, if the UK government can formulate policies to guide the industry and coordinate stakeholders to overcome barriers, the 2030 storage target will be achievable, and the energy storage market outlook is promising.
