Is long-duration storage a viable alternative to carbon-free or high-renewable power systems?

Even though long-duration storage could play a critical role in enabling carbon-free or high renewable power systems, the economics of long-duration storage technologies are not well understood.

Can long-duration energy storage technologies solve the intermittency problem?

Long-duration energy storage technologies can be a solution to the intermittency problem of wind and solar power but estimating technology costs remains a challenge. New research identifies cost targets for long-duration storage technologies to make them competitive against different firm low-carbon generation technologies.

Are long-duration storage applications economically viable?

The economics of long-duration storage applications are considered, including contributions for both energy time shift and capacity payments and are shown to differ from the cost structure of applications well served by lithium-ion batteries.

Can natural gas power plants be displaced by long-duration storage technologies?

The displacement of natural gas power plants with carbon capture and sequestration or the combustion of blue hydrogen by known long-duration storage technologies seems to be unattainable based on current analysis.

Can energy storage technologies improve fossil thermal plant economics?

The research involves the review, scoping, and preliminary assessment of energy storage technologies that could complement the operational characteristics and parameters to improve fossil thermal plant economics, reduce cycling, and minimize overall system costs.
