“…At over 8 hours of duration, the ratio of energy to duration costs changes such that several technologies are at total capital costs comparable to or lower than LIBs. Pumped thermal energy storage (PTES) is anticipated to be cheaper that LIB in most cases, and hydrogen storage costs become more competitive-especially if future cost improvements are realized as described by Hunter et al (2020). This flip with longer durations indicates several technologies might be competitive with LIBs at longer duration.…”

“…Relatedly, the availability of appropriate locations for PSH, CAES or hydrogen cavern storage not only varies the cost but can prohibit these technologies in regions completely. One alternative to the use of geologic storage for hydrogen is to use underground pipes for hydrogen storage (Hunter et al 2020). If this option is chosen, then initial costs and LCOS will be higher, but would not vary geographically as widely.…”

“…Various existing and potential methods can be used, in this case, to create hydrogen from electricity, store this hydrogen, and then then convert it back into electricity for the grid. NREL has contributed to a recent paper on hydrogen energy storage (Hunter et al 2020) as one of several long-duration storage options, and we gather data primarily from this source for this report. Hunter et al (2020) present several options for storing the hydrogen (e.g., in salt caverns and pipes) and several methods for converting hydrogen to electricity, including via a combined cycle turbine, a stationary fuel cell, or a fuel cell designed for heavy-duty vehicle applications.…”

“…The data sources for each of these technologies is recent, but no sole source contained data on all technologies. The electrochemical technologies (except for LIBs, which are updated within this study) are from energy storage cost reports by Mongird et al (2019;2020), data for PTES are from other work at NREL (McTigue et al In Press), hydrogen data are from NREL longduration storage work (Hunter et al 2020), and gravity storage data are from analysis by Schmidt (2018).…”

This report is one in a series of the National Renewable Energy Laboratory's Storage Futures Study (SFS) publications. The SFS is a multiyear research project that explores the role and impact of energy storage in the evolution and operation of the U.S. power sector. The SFS is designed to examine the potential impact of energy storage technology advancement on the deployment of utility-scale storage and the adoption of distributed storage, and the implications for future power system infrastructure investment and operations. The research findings and supporting data will be published as a series of publications. The table on the next page lists the planned publications and specific research topics they will examine under the SFS. This report, the second in the SFS series, reviews the current characteristics of a broad range of mechanical, thermal, and electrochemical storage technologies with application to the power sector. The report provides current and future projections of cost, performance characteristics, and locational availability of specific commercial technologies already deployed, including lithium-ion battery systems and pumped-storage hydropower. These projections will inform the modeling and analysis of power system evolution scenarios planned for later reports in the series.The SFS series provides data and analysis in support of the U.S. Department of Energy's Energy Storage Grand Challenge, a comprehensive program to accelerate the development, commercialization, and utilization of next-generation energy storage technologies and sustain American global leadership in energy storage. The Energy Storage Grand Challenge employs a use case framework to ensure storage technologies can cost-effectively meet specific needs, and it incorporates a broad range of technologies in several categories: electrochemical, electromechanical, thermal, flexible generation, flexible buildings, and power electronics.More information, any supporting data associated with this report, links to other reports in the series, and other information about the broader study are available at https://www.nrel.gov/analysis/storage-futures.html. iv This report is available at no cost from the National Renewable Energy Laboratory (NREL) at www.nrel.gov/publications.

Summary The conversion of CO2 to value‐added chemicals and solar fuels is a “two birds, one stone” strategy addressing two major challenges, global warming and energy crises, simultaneously. Conventionally, several approaches such as electrochemical, biochemical, and photochemical have been deployed to reduce anthropogenic CO2. However, the thermodynamic and kinetic limitations in these approaches prompted the researchers to develop more efficient CO2 utilization methods such as solar thermochemical CO2 reduction. Nevertheless, a lack of an understanding of the state‐of‐the‐art progress in CO2 utilization motivated us to present a timely comprehensive review. Herein, we summarize the traditional thermochemical‐, state‐of‐the‐art thermocatalytic, and solar thermochemical CO2 conversion with a detailed discussion of the working principles, modern techniques used, and mechanistic insights. Moreover, considering the kinetic and thermodynamic perspectives, the choice of catalysts and reaction conditions to selectively produced chemicals such as methanol, formic acid, dimethyl ether, and hydrocarbons, have been discussed. Lastly, we have highlighted the challenges and future trends for ameliorating the CO2 conversion efficiency and commercial‐scale CO2‐based solar fuel synthesis. Therefore, this review would be of substantial importance to the students and researchers to understand the CO2 conversion mechanism and to facilitate the breakthrough progress for scientific and industrial advances in carbon capture and utilization.
