At Hydro Flow Energy, we are driving a sustainable tomorrow by harnessing the limitless potential of tidal energy.
Our proprietary tidal energy converter, TideMaster, is designed to harness the predictable rise and fall of the tide for low carbon power.
The global tidal energy market is growing, yet remains largely underdeveloped. The UK holds a significant share of Europe’s tidal resource and is well placed to lead, especially as demand for clean energy to power green hydrogen continues to accelerate.
TideMaster offers a clear advantage over other renewable technologies. Developed in the UK with a patent pending, TideMaster is designed to be modular and scalable across a range of project sizes. Its design aims to minimise impact on marine life and the surrounding environment while supporting clean energy generation.
Our unique invention Tidemaster generates power from the tidal rise and fall of the ocean every day. Whilst the principle of harnessing tidal energy is nothing new, our approach certainly is.
Join our mission to deliver worldwide tidal energy.
Tidal energy operates on the moon’s predictable schedule — not nature’s unpredictable weather. This makes it uniquely reliable among renewables, delivering steady, forecastable power output every day, regardless of storms, calm conditions, or cloud cover.
TideMaster is the result of decades of engineering experience. Each component is based on established principles, designed to deliver consistent, efficient power with long-term reliability.
Our system is engineered for high efficiency and low maintenance, with no dependency on storage.
Whether installed on the seabed, integrated with existing structures, or mounted quayside, TideMaster’s adaptable design minimises environmental disruption and visual impact while maximising energy generation.
TideMaster is designed so that each unit will monitor performance, anticipate maintenance needs, and give operators clear operational data, with the aim of maximising uptime and reducing downtime.
Built to endure demanding ocean conditions using corrosion resistant materials and sealed systems, TideMaster is engineered for a long service life with minimal maintenance.
TideMaster’s intelligent control systems use real-time diagnostics, adaptive performance tuning, and embedded sensors to continuously optimise each unit with zero manual intervention — delivering maximum efficiency in the harshest marine environments.
Unlike many renewables that require grid support or fossil fuel backup, TideMaster is designed to provide predictable power as a standalone system, reducing reliance on external sources.

TideMaster transforms how tidal energy works. Every system component is engineered for optimal performance in demanding ocean conditions, delivering consistent power output that meets commercial grid requirements — without compromise.
By harnessing predictable tidal patterns, TideMaster is designed for strong, consistent generation, with a streamlined, reliable design intended to keep maintenance low.
TideMaster is designed for consistent generation through continuous operation, whereas solar output varies with daylight and weather.
Traditional tidal stream turbines pose risks to marine life through rotating blades, while tidal wave systems require vast ocean areas for minimal output. TideMaster is designed to reduce impact on marine ecosystems, securing to the seabed, integrating with existing structures, or mounting quayside with minimal environmental disruption.
TideMaster’s components are synchronised to work with tidal flow patterns, not against them — minimising resistance while maximising energy capture through intelligent mechanical design.
TideMaster is engineered to maximise power conversion and minimise losses, using precision components and intelligent load management to increase output while reducing mechanical complexity.
From standalone installations to multi-unit arrays, TideMaster’s modular architecture is designed to be scalable, with the goal of commercial grade reliability and grid integration.
A step-by-step journey from concept towards commercial demonstration, driven by a clear mission to help redefine renewable energy.
Founder Lee Walton built a successful renewable energy business, culminating in a strategic exit to a major German energy company in 2016. This milestone sparked a deeper ambition to address the sector’s bigger challenges.
2009–2016Living by the sea, Lee saw the ocean’s potential to deliver consistent, predictable energy — unlike many other renewables. The initial concept took shape: harness tidal movement for dependable, clean power. Basic principles were identified, and the fundamental idea began to crystallise.
2017The practical applications became clearer as Lee developed a vision for real-world implementation. By 2018, a simple early version was built to test if the core principle actually worked — and it did. This proved the concept could convert vertical tidal energy into rotational energy for electricity generation.
2017-2018Over the next five years, Lee worked relentlessly to refine the design and overcome technical challenges. Components were integrated and tested extensively, with the technology evolving from rudimentary prototypes to increasingly sophisticated systems. The breakthrough came in 2023, when a design solution finally resolved the persistent technical issues.
2018–2023HydroFlow Energy Ltd was officially incorporated in April, with full technical drawings, calculations, and component specifications prepared.
By June, the MVP performed in line with our testing objectives, demonstrating the core principle and successful energy conversion across more than 50 test cycles.
2024The design was further refined and plans developed for both an 80kW prototype and a 1MW commercial unit. HydroFlow secured a dedicated development site at Ramsgate Harbour and engaged with leading industry bodies including Innovate UK and ORE Catapult. Research collaborations began with key universities, strategic investment was secured from high-net-worth individuals.
2025We are moving towards full-scale commercial demonstration, focused on long-term impact and working with partners who share our vision. To find out how to get involved, please contact us.

“I got involved early and haven’t regretted it. The combination of environmental impact and financial upside is rare, and Hydro Flow balances both. It’s smart, it’s scalable, and they’ve executed brilliantly.”
"Investing in Hydro Flow was the right move. It's great to be a part of the journey (and success) of tidal innovation. Highly recommended for anyone aiming for growth on returns!"
“I’m not interested in trends — I back infrastructure that solves real problems. Hydro Flow delivers exactly that. The approach to tidal energy is practical, proven, and positioned for real-world growth.”
Most tidal systems require large turbines, fixed seabed installations, or major infrastructure. TideMaster is modular, relocatable, and designed to work with the tide — not against it — for higher efficiency and lower cost.
TideMaster is based on decades of hydrodynamic engineering and has undergone real-world validation. It’s a functioning solution, not a speculative prototype.
Yes, it can actually enhance marine biodiversity around its structure
