China deploys world’s first sodium-ion grid-scale battery ESS

China deploys world’s first sodium-ion grid-scale battery ESS

The world’s first grid–scale energy storage system has been deployed in China, according to domestic news outlets.

The system was officially put into operation in Taiyuan, Shanxi Province, and is combined with municipal power, solar and charging facilities to form a micro-grid, reported English language newspaper The Global Times.

The system’s major developer was the Institute of Physics, Chinese Academy of Sciences, which has worked on the technology for 10 years.

The institute first demonstrated a 100kWh sodium-ion battery in 2019.

China has proposed a target of carbon neutrality by 2060, and is expected to widely use sodium-ion in a variety of sectors including: electric vehicles, home or industrial energy storage, 5G communication base stations and renewable energy.

Last month, UK battery maker Faradion announced that lithium-ion battery giant Contemporary Amperex Technology (CATL) would begin making sodium-ion batteries from July.

PNNL develops system to prevent lithium-ion ESS fires before they start

Tue, 05/25/2021 - 10:54 -- Paul Crompton

A team from the U.S. Department of Energy’s Pacific Northwest National Laboratory has developed a sensor system that can prevent dangerous conditions developing in outdoor lithium-ion battery cabinets. 

Supported by DOE’s Office of Electricity, IntelliVent automatically opens cabinet doors to prevent buildup of flammable gases if it detects smoke, heat, or gas.

The system can be retrofitted into cabinet-style battery enclosures, such as those used in stationary grid energy storage applications. 

Due to limitations of the product standard, the system is not designed to NFPA-69 (Standard on Explosion Prevention Systems). 

Intellivent, which is available for nonexclusive licensing, was designed to work with a variety of sensors.

A 15-month investigation in the US found that dendritic growth had caused cascading thermal runaway, which in turn caused an explosion at a lithium-ion battery storage facility operated by the Arizona Public Service (APS) utility.

The explosion in Surprise, Arizona, on 19 April, 2019, seriously injured four fire fighters. 

Contributing factors into the explosion included no ventilation for flammable ‘off-gasses’.

Bobby Ruiz, the fire chief in Peoria, Arizona, whose firefighters were injured in the explosion, said: "This is absolutely in the right direction. Getting all doors open early before gas buildup will make the incident safer. 

“It will also increase situational awareness by being able to see if the batteries are smoking or are on fire. And, if extinguishment is needed, we can direct the water right at the modules from a safe distance." 

The Snohomish County Public Utility District’s new Arlington Microgrid and Clean Energy Center, in Everett, Washington, will be the first to install the safety technology when it retrofits a 1.2 MW battery with the IntelliVent system.

Hydroelectric-solar-lithium-ion microgrid marks successful first year at Patagonia National Park

Wed, 09/09/2020 - 10:34 -- Paul Crompton

A “run-of-the-river” hydroelectric power station, photovoltaic installation, and lithium-ion battery storage system have been successfully used to deliver power to facilities in the Patagonia National Park.

The project uses two lithium-ion battery storage units with a combined capacity of 144kWh— from German firm Tesvolt— coupled to two hydraulic turbines and a solar system, both with AC coupling, to achieve a total output of 115kWp.

The power requirements of the park’s facilities were previously provided by diesel generators.

Patagonian installation company SyR Energía planned and executed the project.

Gonzalo Rodriguez (pictured), engineer at SyR Energía, said: “Combining run-of-the-river hydroelectric power and a photovoltaic installation is technically very demanding.

“In winter and spring, the Patagonian rivers are swollen by heavy rainfall and snowmelt from the Andes. The two micro-turbines convert the energy from the water into electricity. 

“In summer, the water level in the rivers drops significantly and the required electricity is then supplied by the photovoltaic installation. Excess electricity is temporarily stored in the battery storage systems.

“This has paid off. The installation has now been running without no problems at all for exactly one year.”

The park is being ‘rewilded’— after decades of heavy overgrazing and desertification— by Tompkins Conservation, a foundation created by the founder of North Face, Douglas Tompkins, and his wife Kristine, previously CEO of clothing company Patagonia. 

Together they have helped create and extend 15 national parks in Chile and Argentina and eventually worked with both governments to protect more than 14 million hectares of land.

Tompkins Conservation purchased the area in 2004 and has since donated the park to the Chilean state, where it is maintained by the Chilean National Forestry Corporation (CONAF).

Eos aims to drive development of its Zinc ESS technology with LOI

Wed, 07/01/2020 - 10:36 -- Paul Crompton

Privately held zinc battery developer Eos Energy Storage signed a letter of intent (LOI) on 24 June with the goal of opening a $225 million finance opportunity by becoming a publicly listed company.

The proposed transaction would provide Eos with $225 million of additional new equity financing, including $50 million of proceeds from a fully backstopped PIPE by B. Riley Financial, assuming no public shareholders of BRPM exercise their redemption rights at closing.

Work on ‘world’s biggest Li-ion ESS’ begins in Southern California

Work has begun on what it said to be the biggest lithium-ion energy storage system, with the ground-breaking of a 100MW/400MWh project for the Alamitos Energy Center in Southern California.

The system by AES Alamitos, a subsidiary of AES Corporation, will use Advancion 5 batteries and control systems from Fluence— the joint venture between Siemens and AES.

Insurer releases ESS fire safety guidelines

International commercial property insurer FM Global has released new fire protection guidelines to combat increased incidences of energy storage system fires.

The US-based insurer said the guidelines are needed because lithium-ion battery-based systems are under growing scrutiny after being involved in fires in South Korea and the US.

Cause of ESS fires in South Korea ‘still unknown’

South Korea’s government said investigators need more time to discover the cause of a series of energy storage system (ESS) fires— and a temporary manufacturing ban continues for several manufacturers.

More than 20 ESS units across the country went up in flames over the past year, the Ministry of Trade, Industry and Energy (Motie) has confirmed.

The government asked public institutions, large multi-purpose facilities and domestic ESS users to stop using their devices as a temporary safety measure.
