BCI pushes lead batteries role in DOE long duration storage program

DOE’s secretary Jennifer Granholm

The US Department of Energy (DOE) has announced plans to reduce the cost of grid-scale, long-duration energy storage by 90% within the decade.

The aim is to deploy “hundreds of gigawatts” of power from renewables onto the grid from energy storage sources that can hold power for more than 10 hours at a time.

The DOE’s secretary Jennifer Granholm announced the ‘Long Duration Storage Shot’ goals to support a low-cost, reliable, carbon-free power grid under the DOE’s Energy Earthshot Initiative.

The ‘Long Duration Storage Shot’ will consider all types of technologies, from electrochemical, mechanical, thermal, chemical carriers, or any combination that meets the necessary duration and cost targets for grid flexibility. 

Pumped-storage hydropower is the largest source of long-duration energy storage on the grid, with lithium-ion the primary source of short-duration storage deployed on the grid in the US.

Granholm said: “We’re going to bring hundreds of gigawatts of clean energy onto the grid over the next few years, and we need to be able to use that energy wherever and whenever it’s needed.

“That’s why DOE is working aggressively toward cheaper, longer duration energy storage to reach President Biden’s goal of 100% clean electricity by 2035. 

“This new initiative will create new manufacturing jobs right here at home and make sure clean, reliable, affordable electricity is available to everyone, including Americans living in remote and underserved communities.”

Lead batteries role in storage

The goal is to achieve breakthroughs that make clean power available anytime, anywhere and support more abundant, affordable, and reliable energy solutions. 

Trade association Battery Council International (BCI) is pushing for lead batteries to be recognised in the program.

BCI has invested more than $100 million in research and development over the past five years— both as independent company members and in collaboration with DOE’s national laboratory system— to investigate how to improve the performance of lead batteries. 

BCI’s executive vice president Roger Miksad released the following statement: ““The lead battery industry looks forward to working with Secretary Granholm and the DOE to achieve the bold goals set within the Long Duration Storage Shot program. 

“The nation’s electric power industry depends on a wide spectrum of technologies – including lead batteries – for functions ranging from backup power supply during system disruptions to facilitating the integration of power from variable resources such as wind and solar to the electric grid. 

“The lead battery industry is an important partner in a suite of energy storage technologies that are becoming increasingly essential to ensuring a reliable and resilient electric power system. 

“A resilient infrastructure needs to have a diverse range of energy sources and given its unique features, lead batteries must be a key part of that mix. In fact, there is no substitute. The lead battery industry, with its unequalled 99% recycling rate, already provides 60% of the worldwide rechargeable battery capacity sold each year. 

“Our strong and reliable domestic supply chain has a proven history of providing readily available and economical energy storage across many essential including renewable energy, and is based on American manufacturing without undue reliance on the imports of products and materials, particularly from countries that are diplomatic adversaries, have inferior environmental protection standards, and engage in human rights abuses.”

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.

Probe launched into Arizona BESS explosion

An investigation is under way after an explosion at a lithium-ion grid-scale battery storage facility in the US operated by the Arizona Public Service (APS) utility.

APS told BEST Battery Briefing today several firefighters and a police officer needed hospital treatment as a result of the “catastrophic failure” of the 2MW/2MWh system at its McMicken facility in the city of Surprise, Arizona.

Firefighters were called to the site after smoke was discovered at the site on 19 April, an APS spokesperson told BBB. The explosion occurred about three hours after first responders arrived.

Newly-formed European company Innolith has said it is on course to bring its inorganic “non-flammable electrolyte” to market within two years, to supercharge the performance of conventional lithium-ion batteries.

Innolith was launched two months ago after acquiring the core technical assets of Alevo in Germany and Switerland, which went into insolvency.

South Australia’s state government has launched an AUD50 million fund to accelerate investment in grid-scale energy storage, needed to address intermittency in the South Australian electricity system.

"This multi-million dollar fund is one of a range of measures the Liberal government is taking to make electricity more affordable and reliable," said Minister for Energy and Mining, Dan van Holst Pellekaan (pictured).

UK power market success for grid battery project

One of the first investor-owned grid-scale lithium-ion battery storage projects in the UK has been pre-qualified to supply backup power to the national grid following a capacity market auction, BBB can reveal.

Grid Battery Storage (GBSL), which formed a partnership last year with Germany’s Siemens to launch four grid-related battery projects, was among the winners of Britain’s capacity market auction.

Changes to UK utility scale energy storage tender process

Changes to UK utility scale energy storage tender process

UK utility National Grid is opening up the tender process to allow smaller companies and non-traditional energy storage methods to compete in the grid-scale UK market.

The company is aiming to simplify its suite of balancing services rather than simply tendering for more individual services targeting specific needs, such as Enhanced Frequency Response (EFR).

Last year the company successfully tendered 201MW of EFR in eight projects totalling £65.95m (with an average price of £9.44/MW of EFR/h) to maintain the grid frequency at 50Hz.

This year the company is re-writing the process in a bid to

group together balancing services with similar requirements and make the process of energy distribution more flexible.

The three initial groups will include Frequency Response, Reserve Energy and Standby & Margin categories, although others may be added.

So for example, EFR and firm frequency response (FFR) dynamic and static will be in the general frequency response category; whereas reserve services and demand turn-up will be grouped in the reserve energy section along with STOR runway.

Work on the new proposal is ongoing, with National Grid planning to announce more details in its Electricity Future Operability Strategy document at the end of March.

The proposals are likely to involve a gradual roll out rather than a sudden step change of the policy.

Stewart Larque, head of Regional Media at National Grid, told BBB: “The intention is exactly the opposite to restricting the opportunities to big players – we want to remove complexity and barriers to smaller players and non-traditional technology types, encouraging greater competition for balancing services.

“The aim is to provide more clarity to all potential providers through having fewer but ‘deeper’ services where providers may tender in specific variables such as speed of response or duration. This will allow all assets, including storage, a better route to market than the current suite of products.

“So, in summary, parties providing response in enhanced timescales will still have a route to market but it will be through those deeper balancing service marketplaces rather than ad hoc periodic tender events.”
