Is the way we store energy the answer?

Energy demands across the world are soaring and the price is still climbing for the end users. As the population grows and more technology (electric cars, more appliances for the kitchen, etc.) is added this strain is only going to increase. To meet the rising demand for energy more pylons, cabling, resources, and man-hours will be required, which could add up to £1,000 per year by 2050 to the end users bill. (Quotation from S&C Electric the power services company.)

 

At the moment, in the UK, renewable energy sources are growing at a steady rate but even they cannot match the growing demand required. Renewable sources are also not constant: the days where there is no wind for the windmills and no sun for the solar panels means less energy is created.

 

Which leads to the question: how can this issue be solved? Are we facing an energy crisis?

A suggestion from Anthony Price from the UK’s Electricity Storage Network is that we look at how the UK stores it’s energy. If energy was stored and saved during the lulls between high demand then it could be used as a back-up for when it soars again. This would cover the gaps in the renewable energy sources as the surplus energy created on great days could be saved for the rainy days. This ruling would also mean that the windmills are not turned off once their quota has been reached and instead could be saved for the future.

 

How to Store Energy: Pumped Hydro and Efficient Batteries?

There are a few ways to store energy from pumped hydro to powerful and efficient batteries (currently being implemented around the world). The Imperial College London’s Energy Futures Lab estimates that if we were to invest in better energy storage that it could save the UK £10bn per year by 2050. The estimates from Lux Research suggest the global industry for energy storage could be worth $100bn in the next few years.

 

Andrew Jones at S&C Electric believes the real difference will happen when smart meters installed in homes will know when to turn appliances off. This could lead to a give and taken relationship when the power is needed elsewhere. For example, turning the television off from standby so the power could be used to balance the rest of the grid. Germany is already starting to implement these types of smart appliances.

 

The bigger picture and Your Bill

 

This could then lead to a larger scale operation where small-scale power generation is feasible. Households and businesses already sell energy back into the grid but soon any device able to store energy could also feed it back. The electric car not being used could turn into the battery required to power something else as connectivity grows. The technology isn’t there yet but it’s headed in that exciting direction and could save the UK a fortune. According to S&C Electric the original £1,000 predicted for end users bills by 2050 it could be as little as £100 if smart grids and energy storage were implemented.
