What is Energy Storage?

Energy Storage is developing as an important resolution to effectively and efficiently store energy generated from renewable energy sources such as Solar PV and Wind. A recent study from IRENA highlighted that innovations with technologies will help facilitate renewable energy integration and storage whilst taking pressure off the grid. Across the globe it is documented that only 3% of power capacity is being stored. In order to limit global warming to below 2°C energy storage capacity needs to triple in size by 2050.

Renewable energy made up around 26.2% of global energy electricity production in 2018 with it expected to rise to 45% by 2040. As the world makes a united effort to reduce carbon emissions and the transition to using green energy sources such as solar and wind power, energy storage solutions becomes vital. As consumers have access to a variety of renewable energy sources generating electricity, the requirement for energy storage will continue to rise in order to balance supply and demand.

What is an Energy Storage System?

Energy storage systems are specifically designed for rechargeable battery systems to store energy from solar arrays, wind turbines or the grid and provide energy when needed to either a home or business. Energy storage batteries are always accompanied with a Depth of Discharge (DOD) meter indicating the percentage of the battery that has been discharged in relation to the complete capacity. There are many different types of Lithium batteries but energy storage systems which adopt Lithium Iron Phosphate (LiFePO4) battery technology can expect exceptional safety, performance and life span of their systems. LiFePO4 batteries are fully protected by a Battery Management System (BMS) that constantly monitors each cell to ensure the battery is being safely charged and is delivering long life cycles.

Benefits of an Energy Storage System

Save Money on Energy Bills

Energy storage solutions can save money for electricity consumers who install a battery in their property. Energy storage solutions are the answer to reducing dependency on peak tariffs from the grid. Charging energy storage batteries during off-peak hours when tariffs are cheaper and discharging the stored electricity during peak hours will result in saving money. Alternatively, when grid demand is high, you can rely on the extra energy generated from your solar arrays which can save you money on your energy bills.

24/7 Energy Reliability

Energy storage batteries allow uninterrupted power for homes or businesses, wherever and whenever you may need it. Methods for storing and discharging electricity enables increased use of renewable electricity production whilst sustaining high reliability in electric source. As energy consumption increases, more strain is put on the grid escalating the chances of power outages. Energy storage can provide back-up electricity during power disruptions.

Reduce Carbon Footptrint 

Research shows evidence stating the strategy of storing renewable energy reduces greenhouse gas emissions. Energy storage systems allow electricity to be stored for later and used when it’s needed. This creates efficiencies and capabilities for those who own energy storage systems – including the ability to reduce your greenhouse gas emissions. Using energy storage systems can drastically reduce your carbon footprint.
