Ambri, LDES Council Release Inaugural Report Detailing Importance of Long-Duration Energy Storage to Achieving Global Net-Zero Goals

LDES Council releases modeling to demonstrate how energy storage technologies can enable net-zero power grids by 2040

LDES members will play a crucial role in limiting the rise in global temperatures

MARLBOROUGH, Mass.–Today, Ambri, Inc. announced the publication of the Long Duration Energy Storage (LDES) Council report, which details how long-duration energy storage technologies will support net-zero goals around the world. Ambri is a contributing author of the report and a founding member of the Long Duration Energy Storage (LDES) Council.

The report concludes that 85-140 TWh of long duration energy storage (>8 hours) can be deployed globally to enable power grids to become carbon net-zero. This will eliminate between 1.5 to 2.3 Gt of CO2 currently produced annually, equivalent to 10-15% of total emissions in today’s power sector, by replacing fossil fuels with renewable energy resources. The report also sets out timeline scenarios for LDES deployment over the coming decades that coincide with recent pledges to deliver net-zero nationally, including the commitments by the United States, United Kingdom, Australia, and India.

“We cannot continue to pass the buck; solving for net-zero necessitates a dramatic increase in grid-scale energy storage to incorporate more intermittent, low-carbon resources into our energy mix. Technology providers such as Ambri are innovating cutting-edge solutions to drive down costs and provide reliable, safe solutions that help address the climate crisis,” said Adam Briggs, chief commercial officer at Ambri. “The LDES Council’s latest report offers facts and modeling that will help us navigate important infrastructure decisions around energy storage and energy transitions.”

The report also describes various types of LDES technologies and analyzes how these solutions contribute to a net-zero grid. A view on technology cost reductions, 60% capex reduction in 2025-40, is presented in the report, as well as sample business cases that show typical sources of value and project returns. The data highlights the need for long-term system planning to attract adequate private upfront investment to support LDES R&D and deployment. Additionally, the report acknowledges that some LDES technologies are in their early stages of deployment and will required targeted investment to achieve the lower cost and scale required to reduce CO2 emissions.

The report follows extensive collaboration between the 24 founding Council members and is based on advanced power systems modelling that uses more than 10,000 real datapoints supplied by its technology providers. The Council’s findings were developed in collaboration with McKinsey & Company, who supported on insight development and analysis.

The LDES Council is a new, CEO-led organization announced during the Conference of Parties (COP) 26 Conference in Glasgow, Scotland that unites energy companies, technology providers, investors, and energy-users to cut carbon emissions through the deployment of long-duration energy storage.

About Ambri

Ambri Inc. has developed and is commercializing a new, long-duration battery technology that will enable widespread use of renewable energy sources, reduce electricity costs, and enable power systems to operate more reliably and efficiently. The liquid metal battery project began at MIT in the lab of Professor Donald Sadoway, and the company was formed in 2010 when the project achieved significant technical breakthroughs.
