Energy Dome, an Italy-based firm which has developed a novel CO2-based long-duration energy storage system, has closed an US$11 million bridge funding spherical.

The convertible funding was led by the Evolution Fund of asset administration agency CDP Enterprise Capital Sgr, along with present investor Barclays by means of the latter’s Sustainable Influence Capital programme concentrating on early-stage firms accelerating the transition to internet zero.

One other present investor, Swiss household workplace Novum Capital Companions, additionally participated within the spherical which brings Energy Dome’s whole fundraising to almost US$25 million, upfront of its Sequence B spherical, which is deliberate for later within the 12 months.

The corporate’s first main undertaking, a 2.5MW/4MWh CO2 Battery facility is now totally operational and the bridge financing will permit it to speed up the event of its bigger, ten-hour period 20MW/200MWh system. Particularly, it would buy orders for the turbomachinery gear wanted for that undertaking, which it described as ‘lengthy lead time’ gear.

A Memorandum of Understanding (MOU) for the utility-scale undertaking was signed with A2A, a European utility, in December 2021 though it was touted again then to be a five-hour, 100MWh undertaking by an Energy Dome spokesperson chatting with Energy-Storage.information.

Energy Dome’s expertise makes use of a thermodynamic cycle to retailer and dispatch energy with a 4-24 hour period. It ‘prices’ by drawing carbon dioxide from a big atmospheric gasholder (the Dome, pictured) and storing it below strain at an ambient temperature, and dispatches by evaporating and increasing the gasoline right into a turbine to generate electrical energy and return it again to the Dome.

Energy Dome says its expertise relies on a novel industrial course of which integrates off-the-shelf parts utilizing established provide chains. It claims an energy storage density 10-20 instances larger than different compressed air energy storage (CAES) options. It concedes it may possibly solely hit two-thirds of liquid air energy storage’s (LAES) density however says its resolution doesn’t require the cryogenic temperatures of LAES which may make the system much less aggressive.

Commenting on the bridge financing, Claudio Spadacini, founder and CEO of Energy Dome stated: “This vital achievement will maintain our formidable development. I wish to welcome CDP Enterprise Capital Sgr into our staff and to thank them, Barclays, and Novum Capital Companions for his or her belief in Energy Dome as we’re poised to change into a number one resolution supplier for the long-duration energy storage market.”

Alongside its MOU with A2A, Energy Dome additionally has a global licensing agreement with Italian power engineering firm Ansaldo Energia for the latter to commercialise Energy Dome’s expertise in its core markets.

Burns and McDonnell providing EPC for RWE


Engineering, procurement and construction (EPC) firm Burns & McDonnell is providing its services for Texas Waves II, a 30MW battery energy storage system (BESS) by RWE.

The 30MW, one-hour system in Scurry County will provide load shifting and grid support services according to a press release. It is expected to come online in late 2022 according to project owner RWE, the Germany-based global energy firm.

Burns & McDonnell described the project as a ‘standalone’ BESS, while in a press release last month that announced the installation of the project’s inverters, RWE said the unit was co-located with the existing Pyron Wind Farm. The EPC firm did say that the battery would charge from the wind farm.

Chris Ruckman, vice president of energy storage at Burns & McDonnell, said: “Adding battery storage in the ERCOT market will be a valuable asset for RWE as they continue supporting their customers with clean, reliable energy.”

ERCOT stands for the Electric Reliability Council of Texas, the grid operator for the majority of the Lone Star State.

Burns & McDonnell said the BESS consists of owner-provided CATL EnerOne battery racks populated with lithium iron phosphate (LFP) battery modules. CATL, based in China, is the largest lithium-ion battery manufacturer in the world today by units sold.

The EPC firm will provide all engineering services for the project, and will install the racks, medium-voltage power station (MVPS) and balance of system (BOS) equipment. The work also includes modifying the existing substation, including installation of a new 34.5-kV vacuum breaker, interconnection details, protective relaying and metering upgrades.

estonia pumped hydro energy storage


State-owned Estonian energy firm Eesti Energia is planning to construct a 225MW pumped hydro energy storage facility, as a part of a wider push to turn out to be unbiased of Russian energy.

The corporate has began finishing up preliminary design and environmental influence evaluation for the works which might be accomplished by 2025-26.

This implies it might be accomplished in time for the Baltic area together with Estonia’s deliberate connection to the continental electrical energy system – and concurrent disconnection from the Russian energy system – in 2026.

The pumped hydro energy storage plant is being deliberate for the commercial space of a now closed oil shale mine within the northeast county of Ida-Virumaa.

Eesti Energia stated it’s not conscious of disused mines getting used as reservoirs for pumped hydro wherever else, and that the idea might be exported to international locations whose land reduction makes standard pumped hydro energy storage tough.

The plan, illustrated within the above picture, is for the higher reservoir to be constructed on a tailings dam, an earth-fill embankment used to retailer byproducts of mining, whereas the closed mine underground will probably be used because the decrease reservoir.

The Baltic states are at present a part of Russia’s electrical energy system however are looking for to disconnect and synchronise with continental Europe’s by a connector between Poland and Lithuania, the Harmony Link project.

Lithuania can also be endeavor massive energy storage tasks as a part of this transfer, in its case building a 200MW, one-hour battery energy storage system (BESS) provided by Fluence. Poland, in the meantime, is building a 200MW/820MWh BESS which can help the deliberate synchronisation of the areas, the state-owned firm behind the challenge has stated.

Trying elsewhere, the pumped hydro energy space for storing has seen just a few substantial large-scale tasks commissioned just lately. Though small in quantity in comparison with BESS models, the scale of the tasks means every one has a big impact on the native grid.

A facility was recently inaugurated in Portugal by utility Iberdrola, whose 1,158MW mixed hydroelectric energy as soon as absolutely operational will enhance the nation’s electrical energy capability by 6%. In Switzerland, a 20GWh system in the Valais mountains also recently came online.

Australian flow battery company Redflow reports 172.3% jump in half-year revenues


Australia-based zinc-bromine stream battery firm Redflow, which has a market cap of practically US$60 million, has halted inventory market buying and selling because it prepares a capital elevate.

The ASX-listed firm introduced the halt right now (11 August) which can proceed till Monday 15 August or when it pronounces the capital elevate, whichever is sooner. It stated the cease in buying and selling was essential to make the announcement.

It has not but revealed how a lot it’s planning to boost however previous strikes, its present dimension and up to date statements could give a tough thought.

The corporate has a market capitalisation of UA$81 million (US$57 million) on the time of writing, and in July 2021 it raised AU$5 million from company finance agency New Expertise Capital Group.

And in an investor presentation launched concurrently with the buying and selling halt announcement, it stated it requires AU$6 million in extra capex to ramp up its Thailand manufacturing facility from 30MWh (finish 2022) to 80MWh by the top of 2023.

The presentation outlined the worth proposition for non-lithium batteries for lengthy period energy storage (LDES) and, extra particularly, its personal zinc bromine expertise.

The corporate claimed to be a frontrunner in medium period energy storage with 250-plus lively deployments with expertise in ‘multi-MWh’ scale, though its largest ever deployment is 2MWh, ordered in March last year by a waste-to-energy facility in California.

It cited commerce group LDES Council’s figures that say world cumulative LDES (outlined as eight hours-plus period) deployments may attain 85-140TWh by 2040, and stated the market is more and more wanting past lithium-ion to do that. It cited 1,124% and 106% will increase in lithium and cobalt costs respectively during the last yr and a half, versus simply 48% and 29% respective rises for zinc and bromine.

And throughout the stream battery house, Reflow claims its expertise has an energy and energy density as much as 3 times greater than iron stream, vanadium and different zinc-based batteries.
