LDES Council and GTI Foundation Forge Partnership to Advance Long Duration Energy Storage as a Key Driver for 100% Renewable Energy on Islands
The Long Duration Energy Storage (LDES) Council and Greening the Islands (GTI) Foundation proudly announce a strategic partnership to promote LDES as an essential component to accelerate the transition to fully renewable energy systems for islands worldwide. The collaboration will focus on knowledge sharing, multi-stakeholder dialogue, and capacity building for 8-hour plus storage solutions.
The two organizations signed a ground-breaking Memorandum of Understanding (MoU) to formalize their cooperation at the Global Renewable Alliance (GRA) Lisbon Future Dialogue in June. The event, designed to be a catalyst for bold ideas and game-changing collaborations for the global energy transition, convened global leaders from politics, energy, technology, and civil society.
This landmark agreement underscores a shared commitment to leveraging the transformative potential of long-duration energy storage technologies to ensure successful transitions towards 100% renewable energy and the sustainable development of islands worldwide.
"The partnership between the LDES Council and the Greening the Islands Foundation presents a transformative opportunity to scale long duration energy storage solutions in island communities,” said Julia Souder, CEO of the Long Duration Energy Storage Council. “By aligning our efforts, we are not only opening new markets for LDES deployment but also driving forward policy innovation and showcasing how islands can become global frontrunners in resilient, net-zero energy systems. Together, we are enabling game-changing applications of LDES technology where it's urgently needed.”
“To achieve 100% renewable energy, the building block of the island model we aim to support and replicate for broad decarbonization and sustainability, renewables plus storage and smart grids must go hand in hand,” said Gianni Chianetta, Chair of GTI Foundation. “Through the partnership with LDES Council, we will showcase how long duration energy is the game-changer for energy security and resilience, especially for non-interconnected islands with tourism-driven fluctuating power demand.”
Under the terms of the MoU, the LDES Council will support specialized technical expertise, resources, and long duration energy storage awareness for the GTI Foundation’s 100% RES Islands Initiative, including developing technical case studies and contributing to capacity-building programs.
Leveraging its long-standing relationships with island governments and extensive global network of island stakeholders, GTI will provide a unique platform for advocacy and enhanced visibility, including event engagements and collaborative publications designed to advance crucial LDES technologies and policies.
The signing of the MoU builds on a successful workshop co-organized on June 18th, 2025, by GTI Foundation and LDES Council, titled “Energy Security for Island Nations: The Role of Long Duration Energy Storage (LDES)”. The event, supported by the Global Renewables Alliance (GRA), the Blue Planet Alliance (BPA) and the Conference of Peripheral Maritime Regions (CPMR) Islands Commission, brought together over 40 stakeholders from around the world, including technology providers, financial institutions, and island stakeholders, for a crucial discussion on how LDES is essential for a complete reliance on renewable energy sources on islands and beyond.
This partnership demonstrates that collaboration, knowledge sharing, and a unified vision are powerful catalysts in guiding islands toward a more sustainable and prosperous future.
About the Long Duration Energy Storage Council
The Long Duration Energy Storage Council is a global organisation advancing decarbonisation by facilitating the accelerated deployment of LDES solutions. The LDES Council's global industry organisation provides fact-based guidance on the deployment of LDES. The LDES Council covers a wide range of LDES technologies, and its members operating in 26 countries span a spectrum of innovation, including mechanical, thermal, electrochemical and chemical solutions. 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. www.ldescouncil.com
About Greening the Island Foundation
Greening the Islands (GTI) Foundation is an international non-profit organisation accelerating the sustainability and self-sufficiency of islands worldwide. By promoting innovative solutions in renewable energy, water, mobility and the circular economy, GTI helps islands lead the way in the global fight against climate change.
Through its flagship 100% Renewable Energy Islands (RESI) Initiative, GTI engages governments, industry leaders and local communities to scale up decarbonisation, strengthen energy resilience, and position islands as living labs for integrated sustainable development. GTI also serves as a global platform to develop solutions, share knowledge and raise awareness, turning island challenges into opportunities and showcasing their role as pioneers of the circular economy and energy transition. www.greeningtheislands.org
