【 Summary 】The California Public Utilities Commission (CPUC) has issued a resolution to procure more than 10.6GW of new energy, using innovative energy storage technologies other than lithium batteries and pumpe

Recently, the California Public Utilities Commission (CPUC) issued a resolution proposing to purchase more than 10.6GW of new energy, including 7.6GW of offshore wind, 1GW of geothermal systems and 2GW of long-term energy storage, of which 1GW is multi-day/weekly duration energy storage (36-160h). The other 1GW is daytime long-duration energy storage (12-36h).

The decision follows a recent report by the California Energy Commission's (CEC) Department of Energy Research and Development, which highlighted the importance of storage resources with a discharge duration of 8 hours or more, and therefore decided to focus on the procurement of 2GW of long-term storage, using innovative energy storage technologies other than lithium batteries and pumped storage. To help governments meet their decarbonisation targets.

Within six months of the resolution's passage, the CPUC will send an "informal request" to the California Department of Water Resources (DWR) asking them to initiate procurement activities. DWR will prepare the tender in 2025 and launch the LDES(and geothermal) tender in 2026; A tender for offshore wind was launched the following year, with the resources to be commissioned between 2031 and 2037.

As part of its decision-making process, the CPUC gathered input from a range of industry stakeholders, including regulators and project developers, some of whom opposed the inclusion of lithium-ion batteries in the procurement. Companies such as Hydrostor, a technology provider developing advanced compressed air Energy storage projects in California and Australia, and Form Energy, a "100h iron-air battery" company, agreed to pay particular attention to some new long-term energy storage technologies in addition to lithium-ion batteries. As a result, the California Public Utilities Commission seems to agree, saying that the purchase of long-term energy storage should not include lithium-ion batteries or pumped storage.

In June, New York State provided $5 million support for 10-100 hours of long-term energy storage projects, and in early July, the US Department of Energy provided $100 million to support more than 10 hours of non-lithium long-term energy storage projects, and California intends to purchase 2GW of long-term energy storage duration ≥12h (excluding lithium-ion batteries, pumped storage), which is a series of policies or financial support. It fully reflects the feasibility of the United States energy institutions actively exploring long-term energy storage duration and technical lines.

With the advancement of global energy transition, the development of long-term energy storage technology is of great significance for reducing greenhouse gas emissions and achieving carbon neutrality goals. In the future, the requirements for energy storage time of the power system will also tend to be longer discharge time, more than 4 hours, cross-day, cross-month and even cross-season will become the exploration and development direction of long-term energy storage.
