The Long Duration Energy Storage Council
The LDES Council is a global organisation advancing decarbonisation by facilitating the accelerated deployment of long duration energy storage (LDES) solutions. The LDES Council provides fact-based guidance on the deployment of long duration energy storage.
The LDES Council’s members span a spectrum of innovation, including mechanical, thermal, electrochemical and chemical solutions.
Our Mission
To fully realise the transformative potential of LDES solutions and achieve a decarbonised energy system, deployments must ramp up significantly. The LDES Council remains steadfast in its commitment to advancing these essential technologies.
By working with members, partners and key decision leaders in governments, regulatory agencies, financial institutions and civil society, the full spectrum of benefits that LDES offers can be unlocked, accelerating the clean energy transition, and helping to ensure a resilient, sustainable and decarbonised energy future for all.
What is Long Duration Energy Storage?
Long duration energy storage is defined as a technology storing energy in various forms including chemical, thermal, mechanical, or electrochemical. These resources dispatch energy or heat for extended periods of time ranging from 8 hours, to days, weeks, or seasons. LDES is critical for decarbonising the energy sectors.
Why We Need Long Duration Energy Storage
LDES is the technology that enables renewable energy to power our grids and accelerate carbon neutrality.
Through LDES, we can accelerate the transition to a clean energy future affordably, reliably and sustainably. Wind, solar and other renewables have become the lowest-cost forms of energy generation but need storage of increasingly long durations to match supply with demand. Today we meet this imbalance by burning fossil fuels. Now is the time to use flexible LDES solutions to achieve net carbon neutrality. The world’s electricity grids will need to deploy 8 TW of LDES by 2040; these deployments have a market potential of as much as $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. These include increasing the share of renewables in the energy mix, providing greater reliability and resilience to grids in isolated or islanded locations, enabling cost-efficient 24/7 renewable power purchase agreements (PPAs), and providing stability and flexibility services to the grid.
