Energy Storage

Energy storage will play a crucial role in enabling the future world energy transition. Along with increasing solar and wind power generation, it will allow a strong decarbonization in key segments of the energy market. As variable renewables energies (RE) grow to substantial levels, electricity systems will require greater flexibility. At very high shares of renewable, electricity will need to be stored over days, weeks or months.

Easy to operate and mantain

Electricity systems already require a range of ancillary services to ensure smooth and reliable operation.
Supply and demand need to be balanced in real time to ensure supply quality (e.g., maintaining constant voltage and frequency), avoiding damage to electrical appliances and maintain supply to users.

All electricity systems require flexibility services, which allow grid operators to react to unexpected changes in demand or to the loss of large chunks of supply.

In today’s power systems, solar and wind power still have limited impact on grid operations. As the share of variable renewable energy rises, however, electricity systems will need more flexibile services through a mix of different storage technologies (highlighted the EChem storage technologies - California Hydrogen Business Council), that will allow the optimal response to the various grid stabilization requirements.

International Renewable Energy Agency (IRENA), in a recent study analyzing the effects of the energy transition until 2050, found that over 80% of the world’s electricity could be derived from renewable sources by that date.

Solar photovoltaic (PV) and wind power would at that point account for 52% of total electricity generation (IRENA a roadmap to 2050). Electricity storage will therefore be at the heart of the energy transition, providing services throughout the electric system value chain and into the end-use sectors.
