Technologies: Energy Storage

Energy storage is one of the most exciting developments in the global energy and transportation industries, and one that we focus on as an innovative energy consulting company.

Energy storage can be located at generation, on grid, or at load. It has a multitude of applications including arbitrage, ancillary services, load shifting, and renewable energy smoothing. Not all energy storage technologies offer the same solutions and we can help you find the most suitable technology for your specific needs.

We have extensive experience in battery energy storage systems (BESS), including lithium-ion technology. We support energy storage applications both in front of and behind the meter.

Energy Storage FAQ

Technically, energy itself is not stored. Rather, it is converted to other forms of energy instead of the original, and then can be stored and reconverted to electricity later, when needed. There are many different ways that the energy can be stored, such as battery, compressed air, flywheel, and pumped hydro storage.

There are different lengths of time that energy can be stored as well. For instance, certain technologies can only store energy on a short-term basis, while others can do so for a longer amount of time. It is important to note that energy storage also involves converting energy from forms that are harder to store, as well as those that are not as economically stable– not just the act of storing itself. 

There are many different forms of energy. It comes in chemical, radiation, electricity, kinetic, latent heat, and more. It can then be stored in many different ways, too, as mentioned above. For example, a very common storage option is that of a rechargeable battery– this stores the chemical energy needed to convert to electricity to charge a cell phone. Fossil fuels, which are commonly used to power our homes and businesses, also store energy.

They store the energy that ancient organisms had derived from the sun. When these organisms died, they were buried and eventually converted into the fossil fuels we know as gasoline or coal. Currently, most energy storage is with hydroelectric dams– which can be conventional or pumped. This is where the energy is stored in a reservoir as gravitational energy.

Electricity is not something that can be stored itself on the grid. Instead, it needs to be converted to other forms of energy so that it can be stored for later use. Once this electricity is needed, the energy will be converted back to electricity so that it can be used for the purpose it is needed for.

When an energy system is being set up, there are different ways that the energy can be stored, so cost-effectiveness is one of the features that will be looked at in order to set up the best energy storage system option. The systems are also limited in the amount of energy that they are able to store. 

The categories of electricity storage include flywheel, battery, compressed air and pumped hydro storage. Each of these has different strengths and can be the best choice for an energy system, depending on the system’s needs. For example, pumped storage symptoms have a longer life than some of the other kinds of energy storage. Their equipment can last up to 50 years. If the system is bolstered with batteries, the equipment may be able to last even longer.

In comparison, battery electricity storage systems only last about 15 years. Pumped hydroelectric storage is associated with dams– the water is pumped back to a high storage dam on the river during off-peak hours, and then the water is released through turbines when needed to be converted to electricity. Batteries, on the other hand, store the energy and then release it electrochemically.
