Long Duration Energy Storage is the technology that enables renewable energy to power our grids and accelerate carbon neutrality. Through long duration energy storage we can transition towards renewable energy in an affordable, reliable and sustainable way. Wind, solar and other renewables are becoming the lowest cost forms of generation but need storage to match supply with demand. Consumer demand means that peaks in the morning and evening need to be met by extra supply. Today we meet the imbalance in supply and demand by still burning fossil fuels. Now is the time to use flexible long duration energy storage to achieve net carbon neutrality. The world’s electricity grids will need to deploy 85-140 TWh of long duration energy storage by 2040 with a market potential of USD 1.5 to 4 trillion.

The need to ensure an affordable, reliable, clean energy system has been exacerbated by recent challenges in the energy sector, which have increased the prominence of energy security on global agendas. Incorporating LDES can help increase the security of supply and create new use cases for renewable energy. LDES can also unlock new opportunities that are not thoroughly addressed by shorter-duration storage solutions. Examples include: helping increase the share of renewables in the energy mix, providing resilience to unreliable grids at long durations (like at isolated or off-grid locations), enabling cost-efficient 24/7 renewable power purchase agreements (PPAs), or providing stability services to the grid.

LDES Council Overview

The LDES Council is a global non-profit with over 60 members in 20 countries. The Council works to accelerate the decarbonization of our world through the acceleration of long-duration energy storage. It provides member-driven, fact-based guidance and research to governments, grid operators and major electricity users on the deployment of long-duration energy storage for society's benefit.

An executive-led organization, the LDES Council spans a wide range of energy storage technologies and includes among its members technology innovators, energy users and investors. The Council publishes findings and reports to encourage the wide adoption of long duration energy storage to replace the use of fossil fuels and accelerate carbon neutrality.
