Powering up the NHS: The rise of battery storage

In our greener, cleaner world, healthcare doesn’t stand aside—especially when it comes to the sustainable sourcing of energy. With 23% of UK greenhouse gas emissions attributed to electricity generation, the NHS is under increasing pressure to revamp its energy strategies, particularly as electricity demand is expected to double by 2050

As the largest health provider in the UK, the NHS has a colossal infrastructure ranging from medical facilities to IT systems and even EV charging stations, all of which contribute significantly to its carbon footprint. In response, NHS Trusts across the country are developing decarbonisation strategies with a keen focus on energy efficiency. Here, battery energy storage systems (BESS) play a critical role, helping to manage the load and support the grid while advancing towards net zero goals.

Why battery storage?

The question arises: why is battery storage pivotal for the NHS? The answer is twofold. Firstly, these systems allow for the storage of renewable energy, sourced from solar and wind, which can be used precisely when it’s most needed. This capability not only keeps electricity flowing during peak times but also aids in controlling costs. Secondly, in the face of soaring wholesale energy costs witnessed over the past 18 months, battery storage offers a buffer against market fluctuations. The government suggests that such technologies could save the UK energy system as much as £40 billion by 2050—savings that can directly translate into more budget allocations for patient care.

Integrating electric vehicle charging

Particularly innovative is the use of solar panels to power EV charging stations within the NHS. By day, these panels recharge a BESS which then powers the charging points overnight—ensuring that vehicles are ready to go without a hitch, powered entirely by clean energy.

As we move forward, integrating innovative technologies like battery storage into NHS operations will not only help in reducing carbon footprints but also in forging a sustainable path for future healthcare provisioning. The shift is not just about energy; it’s about ensuring a healthier, greener future for all.
