Building the network that will carry the WindSurf™ platform to every market that needs it.
Amber Fusion Limited is the commercial and operational engine of the Energy Fusion Technologies (EFT) group. With an established track record across more than 1.9 GW of global energy projects, Amber Fusion operates as a full-service distributed energy platform — originating, developing, financing and managing renewable energy systems for property owners, communities and infrastructure operators across the UK and EU.
Amber Fusion's SolarPlus™ model combines solar PV, micro wind, battery storage and EV charging into a single optimised site-level system, enhanced by AI-driven energy management and underpinned by long-term Power Purchase Agreements (PPAs) of 10–25 years. Revenue streams include direct power sales to tenants and property owners, development and structuring fees, energy trading income, and technology licensing royalties via SiVolt Solar.
Target markets include residential and commercial real estate portfolios, social housing, industrial and logistics sites, community energy systems, and public sector estates — including schools, hospitals and rail infrastructure, directly complementary to Roth Turbines' own market focus. Amber Fusion has a pipeline of identified opportunities across the UK and EU representing 100 MW+ of near-term potential deployment.
Energy Fusion Technologies AB is a next-generation clean energy holding platform, headquartered in Sweden, designed to deliver integrated, off-grid energy solutions for real estate owners, communities, and infrastructure operators.
The company brings together three complementary assets:
Swift Aircraft is the engineering and manufacturing arm of Swift Technology Group, headquartered at Hangar 2, Scottow Enterprise Park, Norwich — the same 600-acre former RAF Coltishall site where Roth Turbines' first production units are being built. Swift became the first new aircraft builder in the UK for 25 years when it opened its manufacturing facility at Scottow in 2018.
Swift Technology Group holds ISO 9001 certification covering the design, manufacture and maintenance of advanced composite and metal structures for the aerospace, aviation, oil & gas and renewable energy industries — the precise disciplines required to manufacture the WS213. The Group comprises seven companies: Swift Aircraft, Swift TG Solutions, Swift TG Energy, AMEL, Europa Aircraft, TWF Solutions and Swift TG Maintenance.
Swift Aircraft has been awarded a UK MoD contract under Project MONET to develop a zero-emission aircraft for the Royal Air Force, working alongside GKN Aerospace on hydrogen propulsion technology.
Carbon-Ion Energy Inc. is a US/UK supercapacitor company with over $40 million invested in proprietary technology since 2013, operating R&D facilities in Abingdon, Oxfordshire and corporate headquarters in New York. The company was formed following the acquisition and merger of ZapGo Limited, a UK-based supercapacitor pioneer, and holds an IP portfolio of over 60 granted patents with a further 40+ in process.
Unlike lithium-ion batteries, Carbon-Ion's Gen 3 supercapacitors use no rare earth or critical minerals, operate across a wide temperature range, and are rated for over 100,000 charge/discharge cycles — delivering a 20-year operational lifespan with no performance degradation. Their cells have been independently validated by Duke Energy and the University of North Carolina at Charlotte (UNCC EPIC), with manufacturing readiness and technology readiness both at level 7.
Phase 1 commercial deployment targets UK water and sewage pump backup power — a market valued at £700 million in 2022 and forecast to reach £2.6 billion by 2032 (CAGR 14%), across 17,892 UK sewage treatment sites. Phase 2 targets grid stabilisation and dynamic containment, where Carbon-Ion's planned Gen 4 supercapacitors will provide sub-second frequency response to stabilise national grids.
LAT Water Treatment has signed a Memorandum of Understanding with Roth Turbines for the supply of WS213 units to power its patented HDH (Humidification-Dehumidification) water purification technology. LAT's systems serve industrial wastewater treatment applications where reliable off-grid power is essential and diesel generation is both costly and operationally vulnerable.
The MoU establishes a recurring supply relationship, with LAT Water Treatment representing a high-quality, contract-backed route into the water infrastructure market. Each deployment creates predictable, long-duration demand for WS213 units and generates recurring revenue under the lease model.
