At Hydro Flow, we are driving a sustainable tomorrow by harnessing the limitless potential of tidal energy.
Our Proprietary tidal energy converter TideMaster is revolutionising maritime power generation for predictable , dependable output around the clock.
The global tidal energy market is projected to reach $8.6 billion by 2033 (approximately £6.8 billion), yet remains largely underdeveloped. With 50% of Europe’s tidal resource, the UK is primed 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 patent protection pending, it’s built for flexibility—scaling from 1MW to 20MW depending on project size. It also delivers major cost benefits, with up to 30% lower capital costs and 40% lower operational costs than offshore wind. Its design is safe for marine life, allowing clean energy generation with no environmental disruption.
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.
In fact, TideMaster is the first tidal generator to overcome all major obstacles to generating reliable, consistent, scalable energy from ocean tides.
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 produces more power per square metre and requires far less maintenance than wind or solar. With higher uptime and zero dependency on storage, the numbers speak for themselves.
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.
Every TideMaster unit continuously tracks performance, anticipates maintenance needs, and provides operators with complete operational intelligence — maximising uptime and power output while preventing costly downtime.
Built to endure the ocean’s toughest conditions using corrosion-resistant materials and sealed systems — delivering years of dependable operation with minimal maintenance intervention.
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 delivers consistent, predictable power as a standalone system. That means genuine energy security, zero reliance on external sources, and complete operational autonomy.
Trusted by major players in renewable technology, Hydro Flow Energy is already turning heads with a solution that stands out for its practicality and potential impact.

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.
TideMaster delivers up to 40% more usable energy than offshore wind by harnessing predictable tidal patterns. With extended generation periods and superior capacity factors, our technology reduces maintenance costs by over 35% through streamlined, reliable design.
TideMaster provides consistent energy generation, while solar output disappears overnight and fluctuates with weather. Our technology delivers substantially more energy per square metre through continuous operation, eliminating the performance variability that limits traditional solar installations.
Traditional tidal stream turbines pose risks to marine life through rotating blades, while tidal wave systems require vast ocean areas for minimal output. TideMaster’s design protects marine ecosystems while delivering superior energy density — 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.
Advanced engineering delivers superior power conversion with minimal energy loss. Precision components and intelligent load management maximise output while reducing mechanical complexity.
From standalone installations to multi-unit arrays, TideMaster’s modular architecture delivers consistent performance at any scale — built for commercial-grade reliability and seamless grid integration.
A step-by-step journey from concept to commercial-ready tidal technology, driven by a clear mission to 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 and scaled prototype exceeded all expectations during rigorous testing — proving the fundamental principle, demonstrating successful energy conversion, and validating component compatibility across 50+ test cycles. In December, the team filed a UK patent application to protect the innovative system.
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, and the company is now preparing to launch its Crowdcube campaign in June 2025.
2025With funding now being raised for the critical 80kW prototype build and testing phase, we are moving toward full-scale commercial demonstration. We’re focused on long-term impact, not short-term wins — working only with partners who share our vision for truly transformative tidal energy that will reshape the renewable sector.
“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.
Tidal energy is one of the most predictable renewable resources on Earth. HydroFlow is positioned with IP-protected technology, real results, and a pathway to market — offering a rare opportunity in a highly underserved sector.
