Energy storage options firm Leclanché claims an addition to its lithium-ion battery can cut back the chance of a thermal occasion by near 80%.

The Switzerland-based agency stated a fire-retardant additive to its electrolyte components composition lowered the chance of a thermal occasion, with out compromising cell efficiency. It known as it a ‘important breakthrough in security’ of its batter expertise.

The achievement has been validated by the German division of Intertek, a British multinational assurance, inspection, product testing and certification firm.

Intertek Germany performed a sequence of business customary nail penetration exams on Leclanché’s 60Ah cell. The check cells have been punctured resulting in an inner brief circuit, however the cells exhibited a far decrease danger of fireplace than the identical cells with out the flame retardant additive.

Pierre Blanc, chief expertise officer, Leclanché, commented: “Whereas all the battery business continues to put appreciable R&D sources into the development of solid-state batteries, there’s a important want to reinforce the protection of immediately’s excessive energy density lithium-ion cell expertise.”

“Most efforts, till now, adversely influence the efficiency or longevity of cells. Leclanché has been in a position to develop a excessive efficiency and excessive energy density lithium-ion cell exhibiting excessive security traits with none unfavorable influence on efficiency or longevity.

“As technological developments proceed to be developed, this can be a essential enchancment in cutting-edge cell expertise, that doesn’t require breakthrough expertise that would nonetheless be a number of years away from business availability.”

The corporate manufactures its battery cells at a manufacturing facility in Willstätt, Germany, utilizing a proprietary manufacturing course of. Electrodes are manufactured in a water-based course of as an alternative of utilizing natural solvents. These electrodes present a excessive stability in the direction of the flame retardant components contained within the new electrolyte, ensuing within the upkeep of cell efficiency.

In addition to constructing its personal battery cells, Leclanché deploys utility-scale battery energy storage methods (BESS). It was lately selected to deploy an 11.9MWh system at a {solar} PV plant in Germany whereas simply final week it lastly broke floor on a solar-plus-storage challenge with a 44MWh BESS in the Caribbean island of St Kitts and Nevis.

The corporate launched its newest technology of modular utility-scale BESS product known as LeBlock in Could 2021, which permit clients to stack collectively 745kWh lithium iron phosphate (LFP) units to multi-megawatt-hour configurations.

Fireplace security and thermal occasion danger discount is a giant matter space for lithium-ion battery producers and energy storage system resolution suppliers as Energy-Storage.news reported on recently.

Leclanché truly had a hearth occasion at a manufacturing unit it operates in Willstätt, Germany, within the early morning of seven April this yr. Two workers have been despatched to hospital as a precaution for doubtlessly having inhaled fumes however have been despatched dwelling a few hours later with a clear invoice of well being and hearth crews discovered no danger to folks within the neighborhood.

Leclanché stated that an investigation was underway, it had activated contingency plans for a short lived cease to manufacturing on the web site and that it didn’t anticipate the incident to trigger delays in fulfilling buyer orders.

pumped hydro energy storage switzerland


A pumped hydro energy storage (PHES) plant with a capability of 20GWh in Valais, Switzerland will start operations on Friday 1 July.

The launch of the Nant de Drance plant, which sits 600m under floor in a cavern between the Emosson and Vieux Emosson reservoirs, marks the conclusion of 14 years of development. It will likely be formally inaugurated in September and its shareholders have invested CHF2.2 billion (US$2.3 billion) within the undertaking.

It options six generators with a nameplate capability of 150MW every which means a most energy of 900MW. The higher Vieux Emosson reservoir, which sits at an altitude of two,200m, holds 25 million cubic meters of water which represents an energy storage capability of 20GWh. Meaning a most period of dispatch of 20 hours.

Utility Alpiq, the primary shareholder within the undertaking with a 39% stake, says the plant will play an important position in stabilising the electrical energy grid as extra renewables come on-line. Swiss nationwide railway firm SFR is the subsequent greatest with 36%, adopted by utilities Industrielle Werke Basel (IWB) with 15% and Canton-owned FMV with 10% of a complete share capital of CHF350 million.

The event concerned 60 corporations and on the peak of development, 650 staff on-site. The facility home cavern measures 194m lengthy, 52m excessive and 32m large and required the excavation of 400,000 cubed meters of rock and the drilling of 17km of tunnels. The Vieux Emosson dam, pictured, was raised by 21.5m which doubled the capability of the reservoir.

Utility Alpiq stated the plant has a ‘yield’ or ‘energy effectivity’ of over 80% which it stated was one of many highest for a PHES plant, presumably referring to round-trip effectivity. For comparability, a 250MW plant in Dubai, which not too long ago approached the midway level of development, is slated to have a round-trip efficiency of 78.9%.

Some CHF22 million was spent on 14 initiatives to offset the environmental affect of the plant, primarily to recreate particular biotopes domestically to encourage recolonisation of the realm by displaced animals and crops.

PHES makes up the overwhelming majority of operational energy storage capability at the moment, however newly operational services have been few and much between lately due the time taken for initiatives.

'Let battery storage NWAs lower Ontario’s electricity network costs'


Energy storage can improve the reliability and decrease the prices of working and sustaining Ontario’s electrical energy distribution community, however present guidelines and rules make that tough.

Batteries are being seen as a useful gizmo to assist add flexibility to electrical energy networks and at transmission and distribution (T&D) grid degree are sometimes described as “non-wires alternatives” (“NWAs”) to expensive investment in new infrastructure.

Nevertheless, in keeping with a brand new report from the commerce affiliation Energy Storage Canada, native distribution corporations (LDCs) in Ontario are discovering “a number of legislative and regulatory obstacles” to deploying energy storage as NWAs and from recovering the prices of investing in them.

In a Visitor Weblog for this website final week, Energy Storage Canada government director Justin Rangooni wrote about how energy storage is a confirmed know-how class that may present peaking capability, flexibility in operations and improve the reliability of networks for LDCs, which function as regulated utilities.

Rangooni noted in his blog that many of the costs associated with investment in energy storage can be offset if storage know-how – so versatile that it’s usually in comparison with a multi-purpose ‘Swiss Military Knife of the grid’ – can be allowed to earn from a number of income streams.

In different phrases, whereas getting used for the LDCs’ functions as NWAs, the storage methods might additionally earn revenues from the wholesale market, for instance.

This market participation would even be appropriate with the regulator Ontario Electrical energy Board’s 2021 directions that distribution corporations ought to utilise applied sciences like energy storage, energy effectivity and demand response to handle their system wants and “keep away from or defer” the necessity to spend money on T&D infrastructure.

The OEB has stated it’s open to permitting LDCs to search out new methods of price restoration and danger allocation and that the utilities needs to be allowed to take part within the wholesale market.

In the meantime Ontario energy minister Todd Smith has explicitly stated that insurance policies supporting NWAs versus conventional types of funding “shall be important in sustaining an efficient regulatory atmosphere amidst the growing adoption of Distributed Energy Assets (DERs)”.

Nevertheless, different codes and pointers that OEB presently has in place, in addition to authorities rules, are stopping this from occurring, as but.

Energy Storage Canada commissioned consultancy Energy Advisory to look into the problems related to LDC deployment of energy storage as non-wires options for its new report. Energy Advisory additionally examined 4 totally different potential possession fashions via which it might work.

Evaluation discovered that even when conventional infrastructure funding had decrease upfront prices, energy storage methods taking part in market alternatives akin to these overseen by the Ontario Impartial Electrical energy System Operator (IESO) would have decrease prices, which in the end are rate-based and handed onto customers (see under).

Income offsets scale back price of distribution companies, in keeping with evaluation within the white paper. Picture: Energy Storage Canada.

The white paper report, ‘Leveraging energy storage for distribution companies: How
maximizing income streams can decrease prices to electrical energy prospects,’ study possession fashions as follows:

  • Utility owned and operated energy storage
  • Third-party owned and operated
  • Utility owned and third-party operated
  • Utility and third-party shared possession and operations

The authors thought-about energy storage to have the ability to present a spread of purposes along with capability for the utilities. These embrace behind-the-meter companies akin to demand administration or peak shaving, in addition to front-of-the-meter companies to the regional or bulk grid, like transmission or wholesale market companies, ancillary companies and extra.

Importantly, the white paper notes that whereas the evaluation weighs up the professionals and cons of every strategy, it doesn’t make particular suggestions in favour of both. The authors and Energy Storage Canada as an alternative hope to immediate consideration and conversations round which can work greatest.

It additionally highlights the particular obstacles, from Ontario’s electrical energy price design regime to obstacles to uncertainty over what kind of revenues may very well be earned from stacking a number of worth streams.
