<p>LDES  also enables renewables integration on electricity grids and maximizes energy utilization, including providing round-the-clock heat for industrial applications and producing alternative fuels like hydrogen from electricity.</p>
<p>The report states that India needs 170 GW of low LDES and 260 GW of high LDES by 2050.</p>
<p><strong>Need for action</strong></p>
<p>In the report, the council calls for faster LDES deployment, procurement, and supportive policies to promote and accelerate existing technologies that deliver immediate and enduring benefits to electricity grids and end users.</p>
<p>LDES Council members have established projects with eight hours or more storage durations on six continents. The council called for all nationally determined contributions to be updated in 2025 to include clear and actionable targets.</p>
<p><strong>Funding</strong></p>
<p>According to the report, funding for LDES solutions increased in 2023, with roughly 70% of investments comprising grants and seed funding. These projects are driven by new decarbonization initiatives by national and regional governments and the sustainability commitments by large corporations, including approximately two-thirds of Fortune 500 companies.</p>
<p>The report estimates that the buildout of up to 8 TW of LDES solutions by 2040 will represent a $4 trillion investment opportunity that could deliver as much as $540 billion in annual system cost savings.</p>
<p><strong>Large-scale deployment</strong></p>
<p>The LDES Council has identified seven enablers for large-scale LDES deployment in the report—raising awareness, assessing need, setting LDES targets, allocating pre-commercial funding, providing market access and long-term revenue visibility, implementing efficient grid pricing, and enabling ease of connection.</p>
<p>The council calls for an increase in government efforts to deploy and scale LDES technology to meet growing energy demands, emphasizing procurement targets in New South Wales and Victoria in Australia, New York, and California in the U.S., Chile, and Italy.</p>
<p>The report states that advancing policy-enabling strategies and setting a specific target for energy storage deployment at COP29 will provide the needed clarity, direction, and accountability for policymakers, industry, investors, and stakeholders to advance LDES deployment.</p>
<p>Corporate funding for energy storage rose 15% YoY in the first nine months of 2024, while it decreased 33% for smart grids in the U.S., according to the 9 M and Q3 2024 Funding and M&amp;A for Storage and Grid Report by <a href="https://mercomcapital.com/" target="_blank" rel="noopener">Mercom Capital Group</a>.</p>
<p>According to a Mercom report, the commercial viability and widespread adoption of energy storage solutions can <a href="https://www.mercomindia.com/india-should-focus-on-domestic-battery-storage-technology-development" target="_blank" rel="noopener">address</a> key issues in clean energy deployment, including grid safety and intermittency, while leveraging the vast potential of various energy storage forms.</p>

					</table><p><a href="https://essinc.com/" target="_blank" rel="noopener">ESS Tech</a>, a manufacturer of long-duration energy storage systems, and Germany-based energy provider <a href="https://www.leag.de/en/" target="_blank" rel="noopener">LEAG</a> have partnered to construct a 50 MW/500 MWh iron flow battery system at the Boxberg power plant site in Germany.</p>
<p>Estimated to cost an initial €200 million (~$218 million), the project aims to accelerate the clean energy transition by combining renewable generation with long-duration energy storage (LDES) using ESS&#8217;s innovative iron flow battery technology.</p>
<p>The venture is expected to serve as a standard model for LEAG&#8217;s plan to deploy 2-3 GWh of storage, transforming its power plant locations.</p>
<p>The project anticipates additional financial support from investors and stakeholders and is scheduled for commissioning in 2027.</p>
<p>ESS&#8217;s iron-based LDES technology utilizes safe and sustainable battery chemistry, offering cost-effective utility-scale energy storage. ESS manufactures its systems near Portland, Oregon, in the U.S. and has already deployed them in commercial microgrid projects, with utility-scale initiatives underway in the U.S. and Australia.</p>
<p>Eric Dresselhuys, CEO of ESS, expressed enthusiasm for collaborating with LEAG, emphasizing its potential to establish a blueprint for utilities and communities worldwide transitioning from coal to clean, renewable energy. Integrating renewables with long-duration energy storage ensures the reliable delivery of clean energy and presents economic opportunities and a cleaner environment for Germany.</p>
<p>LEAG, which operates large-scale lignite mining and coal-fired generation in Eastern Germany, plans to transform the coal-dependent region into Germany&#8217;s Green Powerhouse. The company envisions the development of 7-14 GW of renewable generation, paired with 2-3 GWh of energy storage and 2 GW of green hydrogen production.</p>
<p>The company expects these technologies together to establish a net-zero-carbon baseload energy system. LEAG&#8217;s ambitious plans aim not only to replace baseload coal generation but also to utilize short-duration storage, LDES, and hydrogen for replacing natural gas for grid balancing.</p>

					</table><p>Thermal energy storage (TES), as a form of long-duration energy storage (LDES), can help decarbonize roughly 45% of all energy-related emissions by ensuring that industrial operations requiring heat are optimized affordably, said a report by <a href="https://www.ldescouncil.com/" target="_blank" rel="noopener">Long Duration Energy Storage Council</a> and <a href="https://www.mckinsey.com/" target="_blank" rel="noopener">McKinsey</a>.</p>
<p>Heat storage technologies can offer a variety of storage durations (from intraday to seasonal) and temperatures (from subzero to 2,400°C) and integrate intermittent renewable energy into a firm supply of heat energy.</p>
<p>For instance, TES can firm the variable offshore wind supply into a more stable supply of clean heat for industrial heating, including high-temperature heating. This can completely change the energy-usage pattern of a typical industrial hub.</p>
<p>Further, the report said, “According to the 2022 LDES benchmark results, TES enables cost-efficient electrification and decarbonization of the most widely used heat applications, namely steam and hot air,” the report said</p>
<p>TES can help double the overall installed capacity of LDES to 2 TW-8 TW by 2040. While this will require capital expenditure of $1.6 trillion-$2.5 trillion, it could lead to savings on system costs by up to $540 billion per year.</p>
<p>The findings establish the need for thermal storage to be part of an integrated energy system that includes electrical and molecular storage to accelerate a decarbonized energy system further.</p>
<p><img loading="lazy" decoding="async" class="aligncenter wp-image-44974 size-full" src="https://mercomindia.com/wp-content/uploads/2022/11/Picture1-7.png" alt="" width="567" height="253" srcset="https://mercomindia.s3.ap-south-1.amazonaws.com/wp-content/uploads/2022/11/Picture1-7.png 567w, https://mercomindia.s3.ap-south-1.amazonaws.com/wp-content/uploads/2022/11/Picture1-7-300x134.png 300w" sizes="(max-width: 567px) 100vw, 567px" /></p>
<p>“More LDES enables an accelerated build-out of renewables and greater optimization of grid utilization. When thermal energy storage is part of the mix of diverse LDES technologies, then the results are clear &#8211; long-duration energy storage continues to be a cost-effective, reliable, sustainable, and secure component of our net-zero future,” LDES Council Executive Director Julia Souder said.</p>
<p><strong>LDES costs are declining</strong></p>
<p>The report said that TES solutions have an internal rate of return of 6% to 28% for chemical plants, 22% for off-grid greenhouses, up to 16% for district heating peaker plants, and 16% for alumina refineries.</p>
<p>It is predicted that LDES costs will decline in the following years, suggesting a 25% to 50% overall capital expenditure (CAPEX) reduction of power LDES technologies by 2040. TES capital expenditure is expected to decline by 5% to 30% for power CAPEX and 15% to 70% for energy storage CAPEX.</p>
<p>Incorporating various storage technologies creates an opportunity to optimize the current utilization and future development of fixed infrastructure assets.</p>
<p>The reports suggest that LDES can enable more efficient grid utilization through supply-and-demand management and storage as a transmission asset, thereby reducing costs related to such expansions. This could prove especially beneficial over the next five to ten years, when the bulk of grids will need to be re-designed, given the typical ten-year development timeline of major grid expansions.</p>
<p>Better grid utilization may, in turn, allow the integration of more renewable generation capacity into the system.</p>
<p>The Biden government <a href="https://mercomindia.com/us-announces-350-million-for-long-demonstration-projects/" target="_blank" rel="noopener">announced</a> a $350 million fund for LDES demonstration projects. These storage projects will be built to deliver electricity for up to 10 to 24 hours or even longer to support a low-cost, reliable, and carbon-free electric grid.</p>
<p>Earlier in August, it had <a href="https://mercomindia.com/us-to-invest-23-billion-for-clean-energy-deployment/" target="_blank" rel="noopener">launched</a> two new program offices – the Grid Deployment Office and the Office of State and Community Energy Programs – to drive more than $23 billion in investments to expand the power grid capacity and deploy cheaper, cheaper, cleaner energy.</p>

					</table><p>The Biden-Harris Administration has announced a $350 million fund for Long-Duration Energy Storage (LDES) demonstration projects. These storage projects are built to deliver electricity for up to 10 to 24 hours or even longer to support a low-cost, reliable, and carbon-free electric grid.</p>
<p>The LDES Demonstrations Program will be managed by the U.S. Department of Energy&#8217;s (DOE) Office of Clean Energy Demonstrations (OCED) for up to 11 demonstration projects, which are expected to contribute towards cutting the cost of grid-scale energy storage by 90% by 2030.</p>
<p>The DoE will fund up to 50% of each project&#8217;s cost, including a community benefits plan for each applicant. The program aims to fund projects that will overcome the technical and institutional barriers to full-scale deployment of LDES systems by focusing on various techniques for diverse regions.</p>
<p>Letters of Intent are due by December 15, 2022, and full applications are due by March 3, 2023.</p>
<p>As the U.S. moves towards a carbon-free electric grid that relies on accelerated renewable energy generation, the need for reliable LDES to supply enough energy for long periods when energy generation is either reduced or unavailable becomes critical.</p>
<p>Another part of the projects will be funded by Biden&#8217;s Bipartisan Infrastructure Law and is expected to advance new renewable energy tech, enhance customer and communities&#8217; capabilities to integrate grid storage effectively, increase grid resilience and expand the country&#8217;s global leadership in energy storage.</p>
<p>The new investment will also work with the <a href="https://mercomindia.com/inflation-reduction-act-faster-transition-clean-energy-u-s/">Inflation Reduction Act</a>  &#8211; which provides expanded clean energy tax credits for energy storage installation. The initiative is aimed to give businesses the confidence they require to build and deploy innovative clean energy technologies, which are crucial to reaching the administration&#8217;s goal of a carbon-free electric grid by 2035 and a net-zero emissions economy by 2025.</p>
<p>U.S. Secretary of Energy Jennifer M. Granholm said, &#8220;Advancing energy storage technologies is key to making energy generated from clean, renewable resources—like wind and solar—available for 24/7 use and is critical to achieving a decarbonized power grid and reaching President Biden&#8217;s ambitious climate goals.&#8221;</p>
<p>Recently, DoE <a href="https://mercomindia.com/us-invoking-defense-production-act-spur-clean-energy-industry/">announced</a> a request for information (RFI) inviting comments to determine how it can best utilize the Cold War-era Defense Production Act to spur domestic production of clean energy technologies and strengthen grid reliability. Earlier in August, it had <a href="https://mercomindia.com/us-to-invest-23-billion-for-clean-energy-deployment/">launched</a> two new program offices – the Grid Deployment Office and the Office of State and Community Energy Programs – to drive more than $23 billion in investments to expand the power grid capacity and deploy cheaper, cheaper, cleaner energy.</p>
