This has been a breakthrough year for non-battery storage, with key advances in pumped hydro, power-to-gas, and thermal storage technologies. Many industry players are moving beyond pilot projects to contracted projects, which could lead to increased scale and lower costs. Last July, for example, Highview Power announced a contract with Nebraska-based Tenaska Power Services to help develop up to 4 GWh of cryogenic energy storage plants in the U.S. over a two-year period.

Highview Power Contracts with Tenaska Power Services for US Cryogenic Energy Storage Projects, Highview Power News Release. Highview Power, a global leader in long-duration energy storage solutions, has contracted Tenaska Power Services Co., the leading provider of energy management services to generation and demand-side customers in the U.S., to identify, model, optimize and provide energy management services for up to four giga-scale cryogenic energy storage plants in the United States over two years. The initial project is expected to be developed in the ERCOT market.
GWh-scale liquid-air battery offers storage at half cost of lithium, Recharge News
A UK technology company has unveiled a “cryogenic” energy storage system that it says can store gigawatt-hours (GWh) of renewable energy at half the cost of lithium-ion batteries. Highview Power says its scaleable zero-emissions CRYOBattery technology, which uses liquid air as its storage medium, could potentially replace natural-gas peaker plants that help to balance the grid. A 10-hour, 200MW/1.2GWh system offers a levelized cost of storage of $140/MWh, the company says. By comparison, analyst Lazard puts the price of a similar lithium-ion gas-peaker replacement facility at $285-$581 per MWh.

Fossil fuel plant in England will get 250MWh liquid air energy storage makeover from Highview Power, Energy Storage News. The project is planned as the first of five of the same size to be developed in the UK by Highview, and [company CEO Javier] Cavada said the choice to replace a fossil fuel plant site on the grid was instrumental. “We will be using the same connection and the same electrical infrastructure [as the thermal plant], so there is no need to make [new] transmission lines. So where we are they are decommissioning a fossil fuel plant, we will use the same point of [grid] connection for the cryobattery.”
New RMI Report
Massive Investment is Accelerating the Era of Clean Electrification, Rocky Mountain Institute Blog
RMI’s latest report, Breakthrough Batteries: Powering the Era of Clean Electrification, shows that cost and performance improvements are quickly outpacing forecasts, as increased demand for EVs, grid-tied storage, and other emerging applications creates positive feedback loops for further investment and research, setting the stage for mass adoption. Now, analysts expect the capital cost for new battery manufacturing capacity to drop by more than half from 2018 to 2023.
This momentum is opening new markets, pushing both lithium-ion (Li-ion) and other battery technologies across competitive thresholds for legacy technologies faster than anticipated. That’s important because, although Li-ion remains the leading battery technology, alternative battery technologies nearing commercial readiness will be key to accelerating and scaling climate-critical solutions. For example, alternatives to Li-ion are likely better suited for applications such as long-duration energy storage, heavy trucking, aviation, and EV fast-charging infrastructure.
