Invinity Secures UK’s Largest Vanadium Flow Battery Project

Invinity Energy Systems is set to make UK energy history with the development of its flagship LODES project, a 20.7 MWh vanadium flow battery (VFB) system in South East England. The project will be the largest vanadium battery system ever deployed by the company and one of the UK’s first commercial sites to pair long-duration storage directly with on-site solar generation.

This development arrives at a critical time for the UK’s energy transition. As intermittent renewables like wind and solar grow, the need for grid-scale battery energy storage systems (BESS) has surged. Historically dominated by lithium-ion technology, BESS projects have played a key role in short-term grid balancing. However, lithium-ion systems face challenges in providing multi-hour to multi-day storage, are prone to thermal runaway risks, and often suffer reduced lifespans under heavy cycling.

Vanadium flow batteries, like Invinity’s VS3 technology, offer a compelling alternative. These systems provide long-duration storage, have no risk of fire, lower degradation over time, and are better suited to daily heavy cycling without loss of capacity. Their ability to store and release energy over extended periods is seen as essential to reducing renewable curtailment and cutting fossil fuel backup requirements.

Supporting this shift, companies such as Largo Inc, a major global producer of vanadium, play a crucial role by supplying the essential raw materials needed for these advanced battery systems. The growing demand for vanadium highlights its importance in securing resilient, sustainable storage capacity for renewable energy projects across the UK and beyond.

The LODES project is backed by up to £10 million from the Department for Energy Security and Net Zero (DESNZ) under the Longer Duration Energy Storage (LDES) Demonstration programme. Once operational, the battery will provide crucial grid-balancing services, storing excess solar power during the day for dispatch during evening peaks. This could significantly reduce dependence on gas-fired power stations and lower electricity costs for consumers.

Notably, Invinity has opted to own and operate the asset directly, allowing it to optimise operations, showcase the system’s full capabilities, and serve as a vital reference site for future commercial flow battery deployments. Manufacturing is already underway at Invinity’s facility in Motherwell, Scotland, with the project scheduled for commissioning in 2026.

BYD’s 5-Minute EV Charging Blows Tesla Out of The Water

Chinese electric vehicle (EV) manufacturer BYD has unveiled a ground-breaking charging system capable of delivering up to 1,000 kilowatts (kW) of power, enabling EVs to gain approximately 400 kilometres (249 miles) of range in just five minutes. This advancement positions EV charging times on par with traditional petrol refuelling, potentially transforming consumer perceptions and accelerating the shift towards sustainable transportation.

The new charging technology, integrated into BYD’s “Super e-Platform,” utilizes advanced components such as silicon carbide power chips and high-capacity Blade lithium-ion phosphate batteries. This innovation addresses a significant barrier to EV adoption: charging speed and convenience. By reducing charging times to mere minutes, BYD aims to alleviate “charging anxiety,” encouraging more drivers to transition from internal combustion engine vehicles to electric alternatives.

To support this rapid charging capability, BYD plans to install over 4,000 ultra-fast charging stations across China. This extensive infrastructure development is crucial for the widespread adoption of such high-speed charging technology, ensuring that drivers have convenient access to rapid charging options.

This latest breakthrough places BYD ahead of major competitors like Tesla, whose fastest Superchargers currently offer a peak charging rate of 250 kW, adding approximately 320 kilometres (200 miles) of range in 15 minutes. BYD’s new system more than quadruples this power output, delivering nearly double the range in just a third of the time. If widely adopted, this could challenge Tesla’s dominance in the EV market and force the American automaker to accelerate its own advancements in ultra-fast charging technology.

A Blow to Internal Combustion and Fossil Fuel Dependency

This technological leap could mark the beginning of the end for internal combustion engine (ICE) vehicles. One of the key advantages of petrol and diesel cars has been the quick refueling time compared to the extended charging periods required by EVs. BYD’s ultra-fast charging nullifies this advantage, making EVs a far more viable option for long-distance travel and everyday use. As charging infrastructure expands, the global reliance on fossil fuels for personal transport is set to decline, accelerating the phase-out of traditional gasoline-powered vehicles.

The rapid advancements in EV technology, exemplified by BYD’s new charging system, also starkly contrast with policies advocating for increased fossil fuel extraction, such as former U.S. President Donald Trump’s “Drill, Baby, Drill” agenda. While such policies promote oil and gas production for energy security and economic growth, the electrification of transportation directly undermines their long-term viability. As EVs become more practical and widespread, demand for oil is expected to plateau or decline, challenging the rationale for aggressive fossil fuel expansion policies.

Environmental and Economic Impact

The environmental implications of this advancement are substantial. Faster charging reduces downtime, making EVs more practical for long-distance travel and daily use, thereby promoting a decrease in reliance on fossil fuels. As more consumers opt for EVs equipped with rapid-charging capabilities, there could be a significant reduction in greenhouse gas emissions from the transportation sector, contributing to global climate action efforts.

Economically, countries and industries heavily invested in fossil fuels may face increasing challenges as oil demand wanes. This shift necessitates a strategic pivot towards renewable energy sources and infrastructure, ensuring a smoother transition for workers and businesses currently dependent on the fossil fuel economy.

BYD’s initiative also underscores China’s leadership in the renewable energy sector, showcasing the nation’s commitment to innovative solutions that support a sustainable future. As other manufacturers strive to match these advancements, the global automotive industry may experience a competitive push towards more efficient and environmentally friendly technologies.

In summary, BYD’s introduction of a 5-minute charging system represents a pivotal moment in the evolution of electric mobility, with the potential to reshape consumer habits, reduce environmental impact, and accelerate the global transition to sustainable transportation.

10% of UK Renewable Energy Wasted Due to Grid Constraints

A growing share of the UK’s wind and solar energy is being wasted due to grid limitations, underscoring the need for better energy storage and transmission. Aurora Energy Research estimates nearly 10% of Britain’s planned wind power output was curtailed in 2023, with Northern Ireland seeing even higher rates at 30%.

The issue arises from a mismatch between the rapid expansion of renewables and slower grid infrastructure upgrades. Surplus energy is often wasted due to insufficient storage capacity or transmission bottlenecks, contributing to volatile electricity prices. In 2024, Europe saw a record 4,838 hours of negative electricity prices, while Great Britain recorded 176 hours.

Scotland, home to most of Britain’s onshore wind farms, is particularly affected, as limited transmission capacity prevents efficient energy distribution. Grid operators frequently pay generators to shut down while increasing output from gas-fired plants elsewhere to balance the system.

Battery Energy Storage Systems (BESS) provide a key solution, storing excess electricity and releasing it when needed. Companies such as Fluence Energy Inc (FLNC:NSQ), Gresham House Energy Storage Fund PLC, and Harmony Energy Income Trust PLC are investing in large-scale battery projects to improve grid stability and reduce curtailment.

Harmony Energy Income Trust PLC recently reported a 57% revenue growth, reflecting the growing role of battery storage in balancing supply and demand. Its portfolio, including the Pillswood and Bumpers facilities, now totals 790.8 MWh/395.4 MW. Long-duration BESS assets like these are essential for ensuring grid reliability and minimising renewable energy waste.

Vanadium Flow Batteries (VFBs), championed by Invinity Energy Systems PLC, offer a high-capacity, long-life alternative to lithium-ion storage. Siemens Energy AG is advancing energy storage technology, while ITM Power PLC is pioneering green hydrogen electrolysis as another solution for storing excess renewable electricity.

The UK’s National Energy System Operator (NESO) plays a vital role in managing grid stability. Recent updates to the Open Balancing Platform allow more flexibility for energy providers to bid into the balancing market, improving real-time energy management and reducing waste. These measures, alongside expanded storage capacity, will help mitigate curtailment and enhance renewable energy utilisation.

NESO estimates curtailment and balancing actions added around £4 per month to consumer electricity bills in 2023-24, with costs expected to rise. Globally, curtailment is an increasing issue, with China losing 58.7TWh of wind and solar energy in 2024—enough to power 24 million households.

To address these challenges, the UK must prioritise grid expansion, accelerate BESS deployment, and implement smarter energy management systems to maximise renewable energy efficiency.

Volklec Plans £1bn UK Gigafactory with Chinese Support

Volklec, a Coventry-based battery start-up, aims to build a £1bn gigafactory with backing from former Britishvolt investors and a partnership with Chinese battery supplier Far East Battery. Supported by investment firm Frontive Group, Volklec is learning from Britishvolt’s missteps by securing customers and in-house expertise before committing to large-scale manufacturing.

The company will initially produce cylindrical nickel-rich battery cells for e-bikes and energy storage at the UK Battery Industrialisation Centre, a government-funded pilot facility. By 2025, it plans to expand into automotive, aerospace, and marine power cells, targeting smaller manufacturers that lack the resources for their own battery production.

Focus on Grid-Scale Storage

Volklec aims to enhance the UK’s energy security by producing lithium-ion 21700 battery cells for grid-scale storage. These batteries will help stabilize the National Grid by balancing supply and demand fluctuations, reducing reliance on gas-powered plants, and enabling greater use of renewable energy.

Rapid Deployment Through Established Technology

With a long-term agreement in place, Far East Battery provides Volklec with technical expertise and supply chain support. Production will begin at UKBIC, starting with a 100MWh line, scaling to 1GWh by 2026, and culminating in a 10GWh gigafactory by the decade’s end.

Supporting the UK’s Energy Transition

Volklec’s efforts align with the UK’s push for sustainable power solutions and net-zero emissions. By offering locally produced batteries, the company seeks to fill supply chain gaps and bolster the country’s battery industry, which has been dominated by foreign entities. If successful, Volklec could play a pivotal role in the UK’s shift to renewable energy storage.
