Invinity Selected to Design World’s Largest GWh-Scale Vanadium Flow Battery System

Invinity Selected to Design GWh-Scale VFB System

Strategic Partnership with FlexBase to Develop World's Largest Flow Battery

Invinity Energy Systems plc (AIM: IES), a leading global manufacturer of utility-grade energy storage, is delighted to note FlexBase Group's announcement that, following an in-depth competitive selection process that reviewed proposals from flow battery manufacturers from across the world, it has selected Invinity to design a GWh-scale vanadium flow battery ("VFB") for deployment at the Technology Centre Laufenburg.

Situated in the Swiss municipality of Laufenburg, which is located on the Switzerland-Germany border, the project will feature an AI datacentre and technology campus, integrated with a VFB of up to 1.5 GWh capacity - believed to be the world's largest to date. Invinity's battery solution, which FlexBase will look to expand to 2.1 GWh in subsequent phases, will be used to support the integration of renewable energy onto the site and provide stabilisation to the grid.

The project broke ground in May 2025 and is currently under construction. Invinity will now proceed with the engineering phase of the project, which is expected to take place during 2026 and into 2027 and will generate engineering revenue for the Company, subject to the achievement of various development milestones. Following the successful conclusion of the engineering design phase, a purchase order for the battery system is anticipated to be received, allowing Invinity to initiate phased manufacturing of datacentre-optimized VFB modules for integration into the project.

Further announcements will be made in due course as the project progresses.

Marcel Aumer, Group CEO, Chairman of the Board and Founder of FlexBase Group said:

"Invinity has proven to be the strongest partner by presenting the most compelling overall package with the lowest life-cycle costs (LCOS). Invinity's vanadium flow technology is perfectly suited for our project due to its safety - particularly its non-flammability - its cycle stability, and its flexibility in application."

Pascal Wyss, Chief Innovation Officer at FlexBase said:

"In Invinity, we have found a partner that not only possesses market-ready and internationally proven technology but has also impressed us with innovative, modular solutions perfectly tailored to FlexBase. We look forward to working with the Invinity team to advance the vision of a sustainable energy future."

Jonathan Marren, Chief Executive Officer at Invinity said:

"Having just delivered the biggest vanadium flow battery in the UK, Invinity now enters the engineering phase of what will be the world's largest vanadium flow battery to date. Our longstanding focus on continually building our expertise in flow battery technology has been recognized with the award of this phase of the contract and I am extremely proud of the efforts of the Invinity team in getting us to this position."

May 21, 2026

  • Hyundai WIA to supply advanced lightweight landing gear system for Valo aircraft
  • Agreement strengthens Vertical’s supplier ecosystem as the Company advances toward certification and scaled production

Vertical Aerospace a global aerospace and technology company that is pioneering electric aviation, today announced a new long-term partnership with Hyundai WIA, a subsidiary of Hyundai Corporation and a leading mobility and manufacturing company, to supply the landing gear system for Valo, Vertical’s electric vertical take-off and landing (eVTOL) aircraft.

Under the agreement, Hyundai WIA will develop and manufacture a bespoke landing gear system for Valo, with end-to-end design and production responsibility. Stirling Dynamics, a UK-based engineering company with more than 30 years’ experience supporting certified aircraft programmes, will support Hyundai WIA as a key design partner.

Hyundai WIA’s lightweight, technically mature landing gear solution, combined with decades of advanced manufacturing and mobility experience, makes the company a strong partner for Vertical’s next-generation aircraft.

The partnership further strengthens Vertical’s supplier ecosystem as the Company advances toward certification and commercialization of Valo.

Vertical has now secured key suppliers across major aircraft systems, including Honeywell (flight control and aircraft management systems), Aciturri (airframe structures), Evolito (electric propulsion units), Syensqo (composite materials), and Isoclima (transparencies). The Hyundai WIA agreement marks another important step in establishing a world-class aerospace supply chain for scaled production.

Stuart Simpson, CEO of Vertical Aerospace, said: “As we advance toward certification and industrialization, securing world-class suppliers remains central to our strategy. Hyundai WIA brings deep expertise in advanced manufacturing and high-integrity systems, further strengthening the industrial foundation supporting Valo’s path to commercial service.”

Ho-Young Lee, Vice President of Hyundai WIA, said: “We are proud to partner with Vertical Aerospace on the Valo programme and support the development of next-generation electric aviation. We look forward to working closely with Vertical and Stirling Dynamics to deliver a robust, innovative landing gear solution that meets the highest safety standards and performance.”

The announcement follows Vertical’s successful completion of two-way piloted transition flight, a key technical milestone validating the aircraft’s technology and core operating mode.

Vertical is now progressing toward Critical Design Review (CDR), which establishes the certifiable design baseline and enables the build and test of certification-conforming aircraft. Completion of CDR will lock key design elements, supply chain configuration and certification partner selection ahead of full-scale certification testing and commercial production.

ASTS AI Edge Computing

Background details - ASTS is using Nokia RAN’s for satellite to terrestrial gateway connections.  Nokia is using the NVIDIA CUDA platform as part of the 1 Billion Dollar investment deal they did with Nvidia for their AI-RAN’s software development.  They are currently testing with T- Mobile and other MNO’s, it’s not part of any ASTS gateways currently.

On the last EC Abel mentioned “AI Edge” improvements/compute that can efficiently integrate spectrum to predict traffic based on location.

To me, from a solution standpoint I think it makes sense to predict traffic on one platform, NVIDIA CUDA, so both the RAN and the satellite can be in sync and more easily optimized.  Although it would be possible for ASTS to develop a solution and deploy to their satellite standalone.  My understanding is the ASIC chip manages bandwidth on each satellite; this is the first I heard about AI and traffic prediction and I’m not sure what their approach would be if they develop their own solution.   

Would love to hear everyone thought’s on this.

Double Bubbler: Not my best decision in hindsight… LUNR is over $34 after hours!

As some may recall, I sold my ‘Less than $10k to $1 million’ challenge holding in Intuitive Machines (LUNR) in early April, as I expected greater momentum with Vertical Aerospace (EVTL) after their successful full piloted transition news.

How wrong was I, in the short term at least, with LUNR up almost 50% since and EVTL barely in the green based on currently reported prices in Trading 212. Thankfully I retained all my LUNR shares outside of the challenge given my overall perspective on this prospective space prime.

Had I kept my LUNR challenge shares I would have comfortably doubled my starting capital by now. One of life’s lessons it seems, but the challenge is still doing well overall and up about 68% in the ten months since I began the challenge.

Intuitive Machines (LUNR): A Simply Wall St ‘Weekly Pick’

With other seven million users reported for Simply Wall St this is very welcome coverage. I must admit I am a great fan of SWS given its broad worldwide coverage of listed companies as opposed to platforms such as FinViz which last time I checked was largely focused on North America in my opinion.

When I get time I will update the narrative given the various developments since it was first written last October. However here’s the link to the narrative I wrote for anyone curious…

SES S.A. Satellites (SESG) exceeds Double Bubbler’s forecast in more ways than one!

Last year I made my forecast for…

’€8.19 ($8.87) by the end of 2026*

* Including reinvesting four post-tax dividend payments of €0.21 each paid through 2025 and 2026. It should however be noted that while SES has stated its commitment to stable and progressive dividends, they are not guaranteed. An additional €1.00+ per share distribution could also be derived from a now approved US Federal Communications Commission C-band spectrum auction in 2026/27, however not knowing the exact potential special dividend amount I have not included this.’

I was pleased to see SESG exceed my forecast including dividends the other day. It’s even better to see the share price reach the forecast €8.19 today when ignoring dividends!

Q. For Bubbler - How Did You Knuckle Down on Active Investing?

Hi all -

Question -

u/doublebubbler - In your opinion, what does it take to be an active investor? What are some of your approaches to identifying and sticking with good investments?

Context -

I've been a member of this sub since November and am up £60K in paper gains across ENSI, RDDT, EVTL, LUNR, SESG, MDAI. Thanks DB!!!!

I noticed u/doublebubbler's comment about getting into active investing after leaving the Police, and it resonated with me as I'm considering my next career move. From 2021-2024 I made great money in a business, which has nosedived in the last 2 years (0 revenue atm, for more context see this post in HENRY UK). I'm 29. I have £2M in various stocks and shares (current value, ofc may drop) and am re-assessing the best use of my time, given that successful stewardship of my portfolio could produce substantial growth, or troublesome decline at my own hands.

For those who missed the comment:

Having come all the way from being homeless when I was about eighteen to where I am now, I am over the moon with how my fascination with investing is panning out so far. I just wished I had taken to focusing on active investing earlier in life, as I only really knuckled down with it when I had more time after leaving the Police about ten years ago.
