Light tide energy storage

Is tidal energy a good investment?

Tidal generation combined with energy storage offers the best economic performance at large time scales. The 6-h tidal cycles occurring several times daily makes tidal energy suitable to longer-term (days, months) shaping timescales with minimal energy storage, whereas wind and solar require very large storage for these durations.

Do light-assisted energy storage devices have a bottleneck?

After the detailed demonstration of some photo-assisted energy storage devices examples, the bottleneck of such light-assisted energy storage devices is discussed and the prospects of the light-assisted rechargeable devices are further outlined. The authors declare no conflict of interest.

What is the discharge duration for long-duration energy storage?

Long-duration energy storage has a discharge duration >10 hours and <100 hours. The integration of high shares of solar photovoltaic (PV) and wind power sources requires energy storage beyond the short-duration timescale, including long-duration and seasonal energy storage (Fig. 1).

What are light-assisted energy storage devices?

Light-assisted energy storage devices thus provide a potential way to utilize sunlight at a large scale that is both affordable and limitless.

Can long-duration energy storage solutions 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. (Nature Energy 6, 460–461 (2021))

Can Tidal Generation increase renewable electricity supply?

The quantity of renewable electricity supplied by wind could be increased with minimal curtailment. Tidal generation combined with energy storage offers the best economic performance at large time scales.
