ENERGY STORAGE APPLICATIONS

As the world transitions to decarbonized energy systems, energy storage technologies will be critical for supporting the wide-scale deployment of renewable energy sources.

This overview provides a summary of the different energy storage applications, focused mainly on the electricity system, in order to illustrate the many services that energy storage can provide.

STORAGE FOR SOLAR AND/OR WIND PARKS

Unlock the full potential of your solar and wind power installations. By combining solar energy with storage, you can avoid energy losses from curtailment, while shifting solar and wind energy to times when it is financially most attractive.

STORAGE FOR ROOF TOP SOLAR

By linking your solar roof to storage, you can use as much solar energy as possible yourself. LION STORAGE is working with developers of solar roofs on the business case for installing energy storage on their solar roofs, so that as much green energy as possible can be used even when the sun is not shining.

Energy storage can also be used to reduce peak consumption, which can result in significant savings on transport costs for larger consumers. In addition, there are increasing restrictions on having grid connections adjusted.

There are both supply restrictions and redelivery restrictions, depending on the region. LION STORAGE is working with a developer of solar roofs to calculate the business cases to realize self-sufficient new-build energy. The aim is that the user of the building no longer obtains energy from the grid, but uses the generated energy on his own roof. This goes a step further than energy neutral on an annual basis and results in enormous CO2 savings.

Reliability of the Distribution System

Increase the system operational efficiency and improve the stability during failures. The distribution network is increasingly burdened by new tax sources, such as electric vehicles, and local generation.

Battery storage can accommodate intermittent local generation and isolate the grid from sudden spikes in local load, and so unloading the distribution infrastructure. Energy storage can manage the output of reactive power, usually simultaneously and independently of the real power.

Such reactive power can be used to provide services that maintain the mains voltage. This is a vital local service that protects equipment, maintains power quality and reduces transmission losses. LION STORAGE will soon start a study with a DSO to further develop the use of energy storage in its network, more information will follow.

Renewable Integration

Energy storage is the most responsive and flexible asset available and can neutralize the volatility caused by, for example, renewable energy sources in the grid. Energy storage has no minimum set point and is bi-directional – it can supply power from the network, absorb it and act as a buffer.

Transmission and Distribution

Increase the existing transport capacity without immediately building new lines. Traditional grid capacity expansion projects are large capital investments and have a long lead time.

The strong growth of renewable energy sources cannot be solved by expanding grid capacity alone. In addition, the grid was built to be able to transport the top 10% of peak demand, which usually occurs in less than 1% of the year.

With the energy storage systems of LION STORAGE, these peaks can be absorbed, which means that investments in the network can be partly reduced.

By including energy storage in strategic locations in the distribution network, congestion is avoided and the disconnection of renewable energy sources is avoided.

Fossil Fuel Replacement

Arbitrage

Practice of taking advantage of an electricity price difference in the wholesale electricity market. It is the use of storage to buy energy at a low price and sell it at a high price.
