Redflow completes installation of its biggest zinc bromine flow battery to date

Fri, 01/07/2022 - 09:32 -- Paul Crompton

Flow battery firm Redflow has completed installation of a 2MWh energy storage system for Anaergia in California, US— the Australian firm’s largest single sale of zinc bromide batteries to date.

The energy storage system is designed to reduce peak energy use at clean energy, fertilizer, and recycled water company Anaergia’s Rialto Bioenergy Facility as part of a microgrid. 

The system comprises of 192 zinc-bromine flow batteries, housed in 12 160kWh Redflow Energy Pods and clustered into four strings tied to four 125kW Dynapower inverters.

The microgrid project, funded in part by a grant from the California Energy Commission, consists of the batteries, a biogas conditioning system to support a 2MW biogas-fuelled cogeneration unit and a microgrid control system.

Each of the four battery strings have been successfully charged and discharged and have passed critical acceptance testing criteria. 

The final test of the system will be in January when Siemens plans to integrate the battery into the microgrid controller and the facility can absorb the entire 2MWh load.

Plans for UK’s biggest lithium-ion battery ESS unveiled by Sembcorp

Mon, 12/20/2021 - 10:22 -- Paul Crompton

Plans for a 360MW lithium-ion energy storage system are underway in the UK by energy generation and battery storage firm Sembcorp Energy UK (SEUK).

The system will be built at Wilton International on Teesside, with Sembcorp planning to build out the first phase of the project by 2023, with the rest of the project to follow in stages.

Once completed, the full 360MW of storage capacity will be on one site, where Sembcorp has available land and connections ready to install the batteries.

A competitive tender is being conducted to decide who will supply the energy storage system (ESS).

Grid connection approval is under way and, if successful, the ESS will operate on the wholesale markets delivering balancing services (firm frequency response, fast reserve, dynamic containment) plus new products that power utility National Grid is developing (dynamic moderation and dynamic regulation) and aim to launch next March.

SEUK operates 70MW of batteries, with a further 50MW due to be operational in early 2022. 

 Andy Koss, CEO of UK & Middle East, Sembcorp Industries, said: “Now, more than ever, flexible energy sources play an increasingly important role in maintaining secure and reliable energy supplies. 

“With a growing reliance on renewables, the UK energy system needs to be flexible and able to respond quickly to changes. Sembcorp Energy UK is committed to accelerating the energy transition with sustainable solutions, such as batteries.” 

In comparison, the biggest lithium-ion ESS of its kind in the world was completed by generation firm Vistra in Monterey County, US in August.

The 100MW expansion of the Moss Landing Energy Storage Facility brings the facility's total capacity to 400MW/1.6GWh. 

Building out UK’s power supply 

In September, BEST reported the UK’s largest lithium-ion energy storage system using a Tesla Megapack was being built at Clay Tye in Essex,

The 99MW/198MWh ESS will be delivered through a partnership between Spain’s Fotowatio Renewable Ventures (FRV)— part of Saudi Arabia’s Abdul Latif Jameel group— and the UK’s Harmony Energy.

The Clay Tye ESS beats two other projects in the UK, which are: the 150MW/150MWh Minety battery in south-west England, and a 100MW/100MWh project in Chester, which is due to be commissioned in Q1 2022.

In July 2020, the UK government introduced a secondary legislation to remove barriers for storage projects above 50MW in England and 350MW in Wales.

Removing barriers for energy storage projects were aimed at encouraging bolder investment decisions in larger battery facilities.

Lithium-ion ESS to help Ukraine align its power markets with Europe

Tue, 07/13/2021 - 08:31 -- Paul Crompton

A Ukrainian firm is set to build a 197MW lithium-ion energy storage system after securing a nine-figure loan from the World Bank.

Ukrainian private joint stock company Ukrhydroenergo (UHE) has borrowed a total of $212 million for the project to help link Ukraine’s power grid with the European power grid.

Power grid synchronisation is a Ukrainian strategic objective to create a competitive power market aligned with EU regulations and market practices. 

The project aims to enhance reliability and security of power supply through diversification of energy sources, and access to the EU’s market. 

The project will combine the energy storage systems with solar power plants within four hydropower plant sites (Kyiv, Kaniv, Kremenchuk and Seredniodniprovska) to allow for ancillary services to the national power grid. 

A long-duration battery with a solar power plant will also be installed within Dniester Hydro Power Plant.

The loan includes: a $177 million International Bank of Reconstruction and Development (IBRD) loan; a $34 million Clean Technology Fund (CTF) concessional loan; and a $1 million CTF grant for a new project in Ukraine – Improving Power System Resilience for European Power Grid Integration (Installation of Hybrid Systems for Electricity Production in Ukrhydroenergo). 

Rup Banerji, World Bank regional country director for eastern Europe, said: “This will help Ukraine integrate its power system with the European power grid, reduce the influence of vested interests, and contribute to the achievement of a more energy independent Ukraine.”

The World Bank has already been working to prepare Ukraine’s power infrastructure for synchronisation with the EU power grid under the ongoing Second Power Transmission Project (PTP2).

NeoVolta increases lithium-iron-phosphate battery life to 16.5 years

NeoVolta increases lithium-iron-phosphate battery life to 16.5 years

Battery maker NeoVolta has announced its NV14 energy storage system will include lithium-iron-phosphate batteries that last for 6,000-cycles or 16.5 years.

The system represents a 50% longer life than the firm’s original 4,000-cycle product and represents an engineering milestone for NeoVolta, claim the company.

Neovolta claims the NV14 system has a capacity of 14.4kWh, expandable to 24kWh with the optional NV24 battery, and 7.7kW of instantaneous power discharge.

The claim is based on the home storage batteries being cycled daily, with 6,000 cycles translating to 16.5 years of useful life, based on a full charge and discharge. 

Neovolta did not answer questions put to it by BEST about the technology .

In 2019, a year after it staerrted up, NeoVolta said it was set for a “300% increase in manufacturing capacity” as its moved to a 21,150 sq ft production facility in San Diego.

The move was meant to allow it to increase production of its lithium iron phosphate home battery units to more than 10,000 annually.

Zinc8 pits its zinc-air technology against diesel generator set in data centre tests

Thu, 05/13/2021 - 11:32 -- Paul Crompton
Zinc8 Energy Solutions has signed an 11-month contract to demonstrate its zinc-air energy storage system capabilities against a traditional generator set.

Zinc8 Energy Solutions has signed an 11-month contract to demonstrate its zinc-air energy storage system capabilities against a traditional generator set.

The Canadian firm’s 10kW/80kWh long-duration energy storage system will be tested for resilient backup application, and undergo assessment tests to address unique use cases in data centres. 

The $200,000 project will provide a demonstration of the performance of the company’s technology, combined with an uninterruptible power supply (UPS), to be compared with the performance of a traditional generator set. 

The initial demonstration will be operated in standby and black started. 

The long-term goal is to swap the generator and configure the UPS with combined DC sources that includes long-duration energy storage from Zinc8.

The Zinc8 ESS is based upon patented zinc-air battery technology that stores energy in the form of zinc particles, similar in size to grains of sand. 

When the system is delivering power, the zinc particles are combined with oxygen drawn from the surrounding air. 

When the system is recharging, zinc particles are regenerated, and oxygen is returned to the surrounding air.
