Long Duration Energy Storage Market Overview Report 2025-2026 and Long-term Forecasts to 2046: Technologies, Materials, Projects, Companies, Research Advances, Escape Routes - ResearchAndMarkets.com

DUBLIN--(BUSINESS WIRE)--The "Long Duration Energy Storage Grand Overview: Technologies, Materials, Projects, Companies, Research Advances in 2025-26, Escape Routes, and Markets 2026-2046" report has been added to ResearchAndMarkets.com's offering.

This report gives the reality about LDES, presenting detailed opportunities in materials and systems without the usual exaggeration.

Essential

Long Duration Energy Storage LDES is increasingly essential to cover intermittency of wind and solar power. It is also useful to cover down time of all other green options. Enthusiasts push for trillions of dollars to be spent on it but what is the reality after considering escape routes, paybacks and real-world delays?

The report has the answers with detailed forecasts in 23 lines and roadmaps in three lines for 2026-2046. Importantly, that includes a very close look at research and company advances 2025-6. The result is that over the next 20 years around one trillion dollars will be needed to deliver the lower cost of green electricity resulting from LDES while escape routes are also increasingly activated such as grids and their interconnectors widening across more weather and time zones.

Latest in-depth information

The report has 12 chapters, 17 parameters compared, 22 SWOT appraisals, 23 forecast lines and PhD level analysis throughout, with over 104 companies covered. That includes consideration of units and companies with technologies capable of LDES but currently only used for short-duration storage.

The Executive Summary and Conclusions uses 50 pages to present 23 key conclusions, most of the SWOT appraisals and new infograms, tables and graphs for easy assimilation of the essentials including roadmaps. See all forecasts as tables and graphs with explanation.

Escape routes

LDES escape routes presents the large number of escape routes, deliberate and otherwise, that are arriving to reduce the need for LDES by reducing the need for electricity, reducing the intermittency of green production of electricity and permitting us to viably live with intermittency. Together, they may later reduce demand for the band aid of LDES by at least 50%, something largely ignored by suppliers and their trade association.

Latest technology thoroughly examined

Technology chapters then follow, each with new parameter tables, SWOT appraisals and how research advances 2025-6 change the situation. The authors find that Pumped Hydro is the gold standard of LDES on a host of criteria and that it has much further to go including in forms called Advanced Pumped Hydro.
