Energy storage developments| Sodium–sulphur revisited
BASF Stationary Energy Storage GmbH, a wholly owned subsidiary of BASF and NGK, has released what it calls “an advanced container-type NAS battery”, NAS Model L24.
It is said to offer a significantly lower degradation rate than previous designs, achieving 1% per year, thanks to reduced corrosion in the battery cells. It also has an improved thermal management system, enabling longer continuous discharge (eg 6 hours for a discharge at 200 kW- dc per L24 unit).
These improvements allow projects to be implemented using significantly fewer NAS battery containers and with lower maintenance

costs, say the developers, also noting that “the new concept complies with the latest safety standards for energy storage installations, such as UL1973 and UL9540A.”
transformed
DTE Energy, Michigan’s largest producer of renewable energy, also plans to become a regional leader in battery storage as it converts a portion of its retired Trenton Channel coal power plant site to house a 220 MW/880 MWh battery energy storage facility, with completion expected in 2026.
The cost of the Trenton Channel site’s transformation is significantly offset by $140 million in tax incentives through the 2022 Inflation Reduction Act and its infrastructure investment provisions, DTE notes.
LFP gigafactory: poised for production
Morrow Batteries says it will start mass production at Europe’s first gigawatt-scale factory for prismatic LFP (lithium iron phosphate) batteries in 2024, located in Arendal, Norway. While Morrow’s first factory will initially produce LFP batteries, the company continues
to advance technology for LNMO (lithium nickel manganese oxide) batteries, it says, “driven by a highly qualified team with 25 nationalities based at Morrow’s research centre in Grimstad.” Morrow (backed by shareholders ABB, Siemens, Å Energi, NOAH, Nysnø and PKA),
says its LFP batteries offer “exceptional safety, longevity, and minimal environmental impact”, while LNMO, free of cobalt and lower in nickel and lithium, “leverages the efficiency of manganese to set new standards in sustainability and performance.”

Consented 30 369
RenewableUK’s latest EnergyPulse energy storage report shows that the UK pipeline of battery projects (operational, under construction, consented or being planned) has grown from 57.1 GW to 95.6 GW over the past year, an increase of 67.4% and the second consecutive twelve month period in which the pipeline has Increased by this percentage.
Operational battery storage capacity has grown to 4.4 GW, and the capacity of projects
under construction has reached 4.3 GW. A further 30.4 GW has been consented, 26 GW has been submitted to the planning system and 30.4 GW is at an early stage of development but yet to be submitted.
The piechart shows the UK battery project portfolio (MW).
The average capacity of projects being submitted for planning permission has risen from 27 MW in 2019 to 80 MW currently.
Batteries keep the lights on in Texas
The significant expansion of battery capacity in ERCOT (Electric Reliability Council of Texas) is helping lessen the impact and cost of extreme weather, according to a new report from Aurora Energy Research, and has played an essential part in keeping the lights on, freeing up natural gas power plants from participation in the
ancillary services market and enabling them to move into the energy market during periods of system stress.
During the January 2024 winter freeze, batteries saved an estimated $750 million in day-ahead market costs by fulfilling essential ancillary services and freeing up to 3 GW of gas generation, Aurora
estimates. Throughout the summer of 2023 and especially on 6 September, amid extreme heat and surging power demand, batteries kept the lights on and averted an emergency load-shedding event by dispatching a peak of 2 GW of power when ERCOT reserves were lowest.

auroraer.com Sungrow in store for Saudi Arabia
Chinese PV inverter and energy storage system provider, Sungrow, is partnering with Larsen & Toubro of India to supply 165 MW of PV inverters and a 160 MW/760 MWh energy storage system to Amaala, described as “an ultra-luxury and wellness destination”, on the Red Sea coast, Saudi Arabia. The collaboration is said to “align with Saudi Arabia’s Vision 2030 and China’s Belt and Road Initiative.”
Amaala, to be completed in 2027, will employ one of the world’s largest off-grid energy storage systems, “delivering uninterrupted green power 24/7.” Occupying 4155 square kilometers, Amaala consists of 29 hotels (3900 rooms) and 1200 luxury villas, apartments and estate homes, “complemented by upscale retail, dining, and leisure facilities” – all to be operated solely on renewable energy.

The project is being developed and led by EDF Group and Masdar, for Red Sea Global.
