风能和太阳能必须得到能源储存和稳定发电能力相结合的补充。Sepulveda等人评估了各种可能的长期储能技术的经济价值和系统影响，为指导创新和政策提供了见解。长期储能（LDES）是可再生能源发电中解决不稳定性的潜在解决方案。在这项研究中，我们评估了LDES在脱碳电力系统中的作用，并确定了LDES大幅降低电力成本和取代公司低碳发电所需的成本和效率性能。我们的研究结果表明，能量存储容量成本和放电效率是最重要的性能参数。充/放电容量成本和充电效率起次要作用。能量容量成本必须= 10%。根据目前的电力需求情况，能源容量成本必须
Wind and solar energy must be complemented by a combination of energy storage and firm generating capacity. Here, Sepulveda et al. assess the economic value and system impact of a wide range of possible long-duration energy storage technologies, providing insights to guide innovation and policy.Long-duration energy storage (LDES) is a potential solution to intermittency in renewable energy generation. In this study we have evaluated the role of LDES in decarbonized electricity systems and identified the cost and efficiency performance necessary for LDES to substantially reduce electricity costs and displace firm low-carbon generation. Our findings show that energy storage capacity cost and discharge efficiency are the most important performance parameters. Charge/discharge capacity cost and charge efficiency play secondary roles. Energy capacity costs must be = 10%. With current electricity demand profiles, energy capacity costs must be
