The Energy Storage Technology Collaboration Programme (ES TCP) facilitates integral research, development, implementation and integration of energy storage technologies such as: Electrical Energy Storage, Thermal Energy Storage, Distributed Energy Storage (DES) & Borehole Thermal Energy Storage (BTES).
In the electricity sector, governments should consider energy storage, alongside other flexibility options such as demand response, power plant retrofits, or smart grids, as part of their long-term strategic plans, aligned with wind and solar PV capacity as well as grid capacity expansion plans.
In the transport sector, the increasing electrification of road transport through plug-in hybrids and, most importantly, battery electric vehicles leads to a massive rise in battery demand. Energy storage, in particular battery energy storage, is projected to play an increasingly important role in the electricity sector.
Accordingly, battery energy storage systems are the fastest growing storage technology today, and their deployment is projected to increase rapidly in all three scenarios. Storage technologies and potential power system applications based on discharge times. Note: T and D deferral = transmission and distribution investment deferral.
The majors and Equinor accounted for about 90% of total clean energy investment by the oil and gas industry in 2021 and almost all of the investment tracked so far in 2022. Overall, European companies are out in front for diversified spending, with major roles as investors in offshore wind.
Other storage technologies include compressed air and gravity storage, but they play a comparatively small role in current power systems. Additionally, hydrogen – which is detailed separately – is an emerging technology that has potential for the seasonal storage of renewable energy.

Mainstreaming energy storage systems in the developing world will be a game changer. They will accelerate much wider access to electricity, while also enabling much greater use of renewable energy, so helping the world to meet its net zero, decarbonization targets.
Energy storage is a potential substitute for, or complement to, almost every aspect of a power system, including generation, transmission, and demand flexibility. Storage should be co-optimized with clean generation, transmission systems, and strategies to reward consumers for making their electricity use more flexible.
Making energy storage systems mainstream in the developing world will be a game changer. Deploying battery energy storage systems will provide more comprehensive access to electricity while enabling much greater use of renewable energy, ultimately helping the world meet its Net Zero decarbonization targets.
Energy storage systems allow energy consumption to be separated in time from the production of energy, whether it be electrical or thermal energy. The storing of electricity typically occurs in chemical (e.g., lead acid batteries or lithium-ion batteries, to name just two of the best known) or mechanical means (e.g., pumped hydro storage).
In 2017, the United States generated 4 billion megawatt-hours (MWh) of electricity, but only had 431 MWh of electricity storage available. Pumped-storage hydropower (PSH) is by far the most popular form of energy storage in the United States, where it accounts for 95 percent of utility-scale energy storage.
A recent GTM Research report estimates that the price of energy storage systems will fall 8 percent annually through 2022. There are many different ways of storing energy, each with their strengths and weaknesses. The list below focuses on technologies that can currently provide large storage capacities (of at least 20 MW).
