A method of storing energy produced at one time for use at a later time is compressed air energy storage (CAES). At the utility level, energy produced during times of low energy demand (off-peak) can be released to accommodate times of high demand (peak load).
In terms of its applications, compressed air energy storage (CAES) facilities are similar to pumped-hydro power facilities. But in a CAES plant, ambient air or another gas is compressed and stored under pressure in an underground cavern or container during times of extra electricity instead of being pumped from a lower to an upper pond.
The Global Compressed air energy storage market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The largest and most effective advanced compressed air energy storage (CAES) power plant to date, the 100-MW national demonstration project, was successfully connected to the power generation grid and has become ready for commercial operation in Zhangjiakou, a city in the Hebei Province of north China, reported the Chinese Academy of Sciences.
The Institute of Engineering Thermophysics (IET) of the Chinese Academy of Sciences developed the project technically. During times of peak electricity demand, the power plant can produce 40,000â60,000 houses' worth of electricity, or more than a million kWh yearly.
IET estimates that it can save 42,000 tonnes of standard coal and save carbon dioxide emissions by 109,000 tonnes yearly. In order to compress and store air in massive storage caverns, conventional CAES uses renewable electricity during periods of low electricity demand. When electricity demand is at its highest, high-pressure air is released from the storage caverns and combined with fuel to power turbines.
The benefits of CAES are its substantial storage capacity, low capital cost, lengthy lifespan, safety, and environmental friendliness. One of the most promising technologies for extensive energy storage, it is well acknowledged.
However, the reliance on fossil fuels, the size of the storage caverns, and the low system efficiency of the technology limit its use and promotion. The concept uses an artificial air storage vessel to increase energy density and lessen reliance on massive gas storage caverns.
A power purchase agreement (PPA) has been made by the advanced compressed air energy storage (A-CAES) business Hydrostor for one of its premier large-scale projects in California. For its Willow Rock Energy Storage Centre, Toronto-based Hydrostor and Central Coast Community Energy, one of the several dozen Community Choice Aggregation (CCA) non-profit energy providers in California, have signed a 200MW/1,600MWh energy storage PPA with a 25-year duration.
That is just under 50% of the intended 500MW/4,000MWh long-duration energy storage (LDES) facility's production and capacity over an 8-hour period. This is the company's first offtake agreement, but it is in talks with others to take the remaining resources from the plant.
Having completed one commercial-scale demonstration project in its native nation, the Canadian company, which owns the intellectual property for its technology, pursues projects overseas. A total of two sites in California and one in Australia are where it is now working on large-scale projects with a combined storage capacity of about 9GWh.
Hydrostor is building the 200MW/1,500MWh Silver City Energy Storage Centre in Broken Hill, New South Wales, Australia, together with the 400MW/3,200MWh Pechos Energy Storage Centre in San Luis Obispo County, California. Willow Rock is being built in Kern County. The A-CAES technology is different from its "non-advanced" existing compressed air cousin in that it doesn't require thermal power to warm the compressed air before using it to drive turbines.
As an alternative, water is poured into deep subterranean rock caverns to maintain the air pressure. Also, compared to compressed air, it takes up less room and is more efficient in the roundtrip. Even though that only amounts to about 65% efficiency, Hydrostor is trying to show that it can compete given the size of the projects, the fact that they will be built in largely unpopulated but grid-connected regions of the US and Australia, and the fact that they will operate for more than 50 years.
The utility-scale projects being developed by the business are being developed at different phases. For the two California projects, applications have been made for certification (AFC), the procedure by which all electricity generating units obtain permits to produce electricity.
After confirming that Hydrostor's application was complete in July of last year, the California Energy Commission (CEC) is rumoured to be close to making a decision.
Engineering and design studies were to be carried out for Hydrostor by the construction firm Kiewit.Central Coast Community Energy (3CE) and the other CCAs in California offer their member-customers the option of choosing the source of their energy, and CCAs are increasingly active in acquiring sustainable energy resources in the state. 440,000 or so customer accounts are with 3CE.
The majority of that has been solar PV, and more recently, solar-plus-storage and standalone lithium-ion battery storage with a capacity of up to 4 hours. However, lately, a group of California CCAs staged one of the first long-duration storage solicitations in the history of the planet.
They continue to advocate for and promote emerging technologies that will remove their communities' reliance on fossil fuels. By doing this, they also provide a model for other regions to follow and contribute to cleaning up the grid in California
