Benefits of Energy Storage Systems: Future Renewable Energy Systems

Energy storage systems are systems which make it possible to store power that has been produced for use at some future point. The energy does not have to be consumed as soon as it is produced. If renewable energy sources are going to play a bigger role in the world, energy storage systems will have to play a part. Here are some of the benefits of energy storage systems, and what they bring to the table.

How Electric Cars Could be a Simple Solution.

Some of the more forward thinking ideas from the energy storage industry are to link with the automotive industry. Modern Electric cars already have very simple energy storage systems, but currently are severely limited due to the poor storage capacity. If current large energy storage system like Prudent’s 7kWh Vanadium Redox Battery (VRB) can be compressed in the future. A new opportunity could develop to use your electric car as an energy storage system for your house.

Future smart energy grids could use the millions of electric cars as mobile energy storage units. The new vehicle-to-grid idea could see your future electric cars make you money while you sleep.

While currently most energy storage systems are only commercially available many domestic systems are in development with Atraverda and Prudent Energy bringing products out in 2013-2014. The market leader Prudent Energy has a modular VRB unit which is perfect to allow scalability of an energy storage system. Currently the largest commercial projects have around a 10MW storage capacity and could power multiple buildings for weeks in emergencies.

Store Energy When It Cannot Be Produced

Another problem with renewable energy is that it can sometimes be difficult to produce under certain conditions. For example, solar panels cannot produce energy on cloudy or rainy days. Wind turbines can’t make energy when the wind isn’t blowing. With energy storage systems, users could hold onto the power that is made by these systems, and then use it when power can’t be produced.

By storing energy in this manner, it would be possible to make renewable energy sources much more reliable. Users would be able to depend on the energy sources regardless of what was happening. They wouldn’t have to be concerned about what the weather was going to bring for the day. They would know that plenty of power would be there until the weather was ideal again.

Further Considerations

The current technological advancement of energy storage systems requires a lot of external devices such as Power Conversion System (PCS) and a large control system in order to keep the power management at the required levels. At the rate of development smaller domestic units are unlikely to be mass produced for many years.

The projects currently been research would do well to integrate solutions to other world problems into their designs. Doing so would drastically increase the investment in energy storage systems and could make a massive difference to future projects like vehicle to grid or reducing the world carbon emissions. If the renewable energy industry is going to take off, and eventually supplant fossil fuels as the primary source of energy, energy storage systems are going to have to be more prominently used on a regular basis. Without energy storage systems, renewable energy simply is not practical. When users have to wait until conditions are ideal to get the energy they need, it can be very frustrating. With an energy storage system, renewable energy users can get exactly the energy they need when it’s required.
