UK-based energy innovator Pivot Power is developing the world’s largest hybrid energy storage system in Oxford.

Pivot - a subsidiary of EDF Renewables UK - will receive tech assistance from Invinity Energy, which will supply a 50MW lithium-ion battery and a 2MW vanadium redox flow battery.

This combination will combine the high-power capabilities of the lithium-ion battery with the non-degrading qualities of vanadium redox flow tech. It is expected that this hybrid combo will yield a robust system capable of meeting the area’s complex energy requirements. 

Furthermore, Habitat Energy will be providing ML-based (machine learning) optimisation of the system, which will allow it to more effectively meet power requirements and streamline the integration of renewable energy sources to the grid.

Oxford: modernising energy

At the root of these significant changes is a plan to reshape Oxford’s transportation infrastructure with the introduction of EVs (electric vehicles). Oxford City Council has received its first batch of EVs as part of Energy Superhub Oxford (ESO), a world-class initiative to decarbonise energy and transport throughout the city. 

Speaking about the company’s place in this overarching scheme, Tim Rose, ESO Programme Manager at Pivot, said, “Pivot Power’s purpose is to accelerate the UK’s transition to a clean, electric future.

“The smart power network we are installing in Oxford will deliver flexible, reliable power at scale to fast-track EV adoption.

“As part of EDF Renewables UK, our aim is to replicate this model throughout the UK, supporting greater renewable generation and delivering power where and when it is needed to enable mass-scale, rapid electric vehicle charging.”

Harnassing the energy transition

Funding of £41mn spread over three years has been agreed by ESO, which is part of the government plan ‘Prospering from the Energy Revolution Challenge’ (PERC).

Rod Saunders, Deputy Challenge Director for PERC, called the project an important technological stepping stone to achieving modern smart integration with energy systems and meeting the UK’s net-zero carbon by 2050 target.

“ESO demonstrates a model for cities that can be replicated nationally to cut carbon and improve air quality. 

“By integrating innovative technologies for maximum impact it’s demonstrating the opportunity to harness the energy transition for lasting environmental and economic benefit.”

Drax advances biomass strategy with Pinnacle acquisition

Drax is advancing biomass following Pinnacle acquisition it reported in a trading update

Drax' recently completed acquisition of Pinnacle more than doubles its sustainable biomass production capacity and significantly reduces its cost of production, it reported in a trading update.

The Group’s enlarged supply chain will have access to 4.9 million tonnes of operational capacity from 2022. Of this total, 2.9 million tonnes are available for Drax’s self-supply requirements in 2022, which will rise to 3.4 million tonnes in 2027.

The £424 million acquisition of the Canadian biomass pellet producer supports Drax' ambition to be carbon negative by 2030, using bioenergy with carbon capture and storage (BECCS) and will make a "significant contribution" in the UK cutting emissions by 78% by 2035 (click here).

Drax CEO Will Gardiner said its Q1 performance had been "robust", supported by the sale of Drax Generation Enterprise, which holds four CCGT power stations, to VPI Generation.

This summer Drax will undertake maintenance on its CfD(2) biomass unit, including a high-pressure turbine upgrade to reduce maintenance costs and improve thermal efficiency, contributing to lower generation costs for Drax Power Station.

In March, Drax secured Capacity Market agreements for its hydro and pumped storage assets worth around £10 million for delivery October 2024-September 2025.

The limitations on BECCS are not technology but supply, with every gigatonne of CO2 stored per year requiring approximately 30-40 million hectares of BECCS feedstock, according to the Global CCS Institute. Nonetheless, BECCS should be seen as an essential complement to the required, wide-scale deployment of CCS to meet climate change targets, it concludes.
