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.

What drives the cost-effectiveness of long-duration storage technologies?

Moreover, the researchers conclude that energy storage capacity cost and discharge efficiency are the most critical drivers for the cost-effectiveness of long-duration storage technologies — for example, energy capacity cost becomes the largest cost driver as discharge duration increases.

How can a large-scale energy storage project be financed?

Creative finance strategies and financial incentives are required to reduce the high upfront costs associated with LDES projects. Large-scale project funding can come from public-private partnerships, green bonds, and specialized energy storage investment funds.

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 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.

What are mechanical energy storage methods?

Innovative mechanical energy storage methods, such as CAES and LAES, use the physical states of air under various situations to store and release energy . Large-scale LDES is a notable feature of CAES, which compresses air and stores it in underground caves or containers to be released later to generate power.
