\n This graph of multiscale energy storage needs for a hypothetical 95% carbon-free power system assumes 28.4% wind and 51.5% solar PV energy share. Energy storage requirements are shown for (a) Hourly net load over the course of a year; (b) Hourly net load for a given day; (c) Total daily net load for a given week; and (d) Total monthly net load for intra-month energy shifting for the year. p.u. is per unit value based on the maximum absolute net load for each timescale.

With variable renewable energy (VRE) expected to become a much larger share of the global energy mix, storage solutions are needed beyond short-duration timescales, such as standard commercial batteries, which are suitable for covering hourly differences in net load.<\/p>\n

A Nature Energy<\/i> “News<\/a> & Views” article by National Renewable Energy Laboratory (NREL) research engineer Omar J. Guerra describes research needs for longer-duration and seasonal energy storage solutions. The article, titled “Beyond short-duration energy storage,” reviews important practical implications of a research article contributed by Nestor A. Sepulveda and colleagues, as well as research opportunities to develop a stronger understanding of how long-term and seasonal storage technologies can become cost-effective and grid-supportive energy solutions.<\/p>\n

Guerra’s article draws attention to the need for new system-level models that resolve the integrated aspects of longer-duration storage options, including seasonal timescales.<\/p>\n

Longer-duration energy storage technologies could include mechanical, such as pumped hydro; electrochemical, such as novel battery technologies; chemical, such as hydrogen; or thermal, such as molten salts. Guerra’s article describes recent studies showing how these technologies can provide grid-scale storage in the long term; however, more detailed analysis is needed to motivate industry investment and determine the complete value of upcoming technologies to the grid.<\/p>\n

This review summarizes the research needs to arrive at more comprehensive results: better temporal representation for production cost models and capacity planning models; more integrated models showing how storage technologies behave with varying loads and levels of renewables; and better-informed experimental validation of storage technologies.<\/p>\n

Overall, this article suggests that with higher detail and more representative modeling, the energy industry will have a more complete understanding of how long-duration storage technologies could displace carbon-intensive energy sources, provide resilience and transmission deferral benefits, and become economically viable investments.\n <\/p>\n\n
