In Search for Cheaper, Longer Energy Storage, Mountain Gravity Could Eventually Top Lithium-Ion

Mountain gravity energy storage could be a viable way to store electricity for longer durations and at larger scales than lithium-ion battery storage can, according to a study recently published in the academic journal Energy. The idea of gravity as a form of storage is an example of ongoing research into additional storage options beyond lithium-ion batteries. Despite large cost reductions over the past several years, some experts still view lithium-ion systems as not economically-efficient enough at scale to fully back up the amount of renewable energy expected to come onto the grid due to states’ long-term clean energy goals.

Storage Player Unveils US Battery Plant Plan

US company Kore Power is planning to build a lithium-ion battery manufacturing plant in its home country to support global growth efforts for its energy storage system. The 305,000-square-metre plant aims to support up to 2000 jobs by providing batteries for the Mark 1TM storage system. Kore Power said it is reviewing potential sites in a handful of states within the US and has narrowed the search down to places with broad access to labor and logistics hubs.

Duke Energy Carolinas Partners with Anderson County, S.C., on Major Battery Storage Project

Duke Energy Carolinas is partnering with Anderson County, S.C., to build an energy storage project at the Anderson Civic Center that will be part of the company’s long-term strategy to integrate battery technology into the smart-thinking grid it is building in the Carolinas. The battery project will also provide power to a facility that is critical during emergency situations, such as being the site of a hurricane evacuation shelter. This project is part of the company’s ongoing plans to invest $500 million in battery storage projects across the Carolinas over the next 15 years.

Energy Storage with Second Life Batteries by ENGIE and Umicore

On October 8, 2019, an industrial ‘second life’ battery system was first put into use in Belgium. The system consists of 48 used batteries from electric cars, and now forms one large storage battery of 1.2 MW or 720 kWh. Now that the electric car is gaining popularity, the question arises as to what will happen to all batteries once the cars are no longer being used; the partnership between Engie and Umicore will develop applications for these ex-EV batteries.

The Nobel Prize in Chemistry 2019

The Nobel Prize in Chemistry 2019 was awarded jointly to John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino ‘for the development of lithium-ion batteries.’ This lightweight, rechargeable and powerful battery is now used in everything from mobile phones to laptops and electric vehicles. It can also store significant amounts of energy from solar and wind power, making possible a fossil fuel-free society.

‘Germany’s Largest’ EV Battery-Powered Stationary Storage System Will Give Grid Flexibility

A battery storage project using second-life electric vehicle (EV) batteries is set to be built in Germany, with an aim of developing an installed capacity of 20MW. The project is being billed as the largest stationary electricity storage system using EV batteries in Germany, following on from an initial 45MW project in France. The stationary storage system is to be built using EV batteries compiled in containers, using both second-life batteries and new batteries stored for future use in standard replacement during after-sales operations.

Battery System to Provide Frequency Regulation for PJM

A 72 MW/72 MWH battery system owned by a global independent power producer is expected to soon start providing grid services in PJM territory, signaling the storage industry’s increasing maturation and ability to compete with traditional resources. Industry supporters have argued that getting more storage online to support renewables integration and provide other grid benefits would require compensation schemes that allow storage to compete.

DOE Announces Phase 1 Winners of Battery Recycling Prize

The U.S. Department of Energy announced the 15 winners of Phase 1 of the Battery Recycling Prize, a prize that aims to reclaim and recycle critical materials (e.g., cobalt and lithium) from lithium-based battery technology. For a total of $1 million in prizes, these projects focus on cost-effective recycling processes to recover as much economic value as possible from spent lithium-ion batteries.
