5 ways battery energy storage can help meet net zero goals

Organisations across the UK are ramping up their efforts to decarbonise and we know that energy managers often have tough targets to meet – at the same time as balancing budgets.


In our first blog in our series aimed at energy managers, we’ve listed five ways that battery energy storage can help in the drive to reduce carbon emissions and support decarbonisation measures.

01. By storing solar power

Many organisations have gone down the route of installing solar panels in an effort to reduce their carbon emissions. But making sure that you make the most of every last bit of that energy generated is key. It’s often the case that solar panels might generate more energy than you need. So what happens to the excess? Usually, it’s fed back into the grid. In fact, we worked with one client with a multi-building site who was exporting 15% of their solar power back to the grid – that’s 15% of their own solar energy that’s not being used to power their site.

By incorporating battery energy storage alongside your solar array, you can store this excess and use it whenever it’s needed. That means you’re using more renewable energy on-site and avoiding falling back on non-renewable energy sources.

02. By supporting the electrification agenda

Another decarbonisation measure that many organisations are adopting is to decarbonise their heating and their vehicles. Ironically, these measures both reduce carbon and increase energy use at the same time. In the case of electric vehicles in particular, it is often the case that additional power capacity is required to support the power demands of charging at scale.

This is where battery energy storage can help, by providing the additional power needed and overcoming the power constraints that lots of sites face. Not only that but by storing and using electricity from renewable sources, carbon emissions are reduced by charging using greener energy.

03. By becoming the 'brains' of your green microgrid

The power of a battery energy storage system (BESS) goes beyond just storing energy. Its intelligent management system can bring together elements of your green microgrid – like heat pumps, solar arrays and EV charging – and balance their various power demands, smoothing out fluctuations and releasing green energy where and when it’s needed.

04. By maximising your use of greener grid energy

When you do need to draw energy from the grid, making sure it’s at times when renewable energy is readily available will increase your site’s overall green power percentage. A BESS can be programmed to draw down energy at specific times and store it for use when grid energy is non-renewable.

05. By giving EV batteries a second life – and supporting your scope three reductions

At Connected Energy, all our BESS are created using second life batteries. These are batteries that have had a first life in a vehicle but still have a huge amount of capacity for use in less intensive applications like stationary battery energy storage – more than enough to create high performance systems.

This doubles each battery’s lifetime, reduces the need for new battery manufacturing, and results in bigger carbon savings – a recent study by Lancaster University showed a 450tonnes C02e saving for each MWh of second life system installed, compared with a BESS using new lithium-ion batteries.
