Inyanga Marine Energy Group

What Inyanga Marine Energy Group does

Inyanga Marine Energy Group is a privately held UK marine renewable energy company headquartered in Penryn, Cornwall, with operations in two divisions: Inyanga Maritime, providing offshore engineering, installation, and consultancy services for the marine renewables sector, and HydroWing, developing modular tidal stream energy converters. The company's flagship product, the patented HydroWing system, combines a modular seabed-mounted substructure with Tocardo T3 bi-directional turbines (2x600kW each, 14m rotor diameter) and a passive pitch blade mechanism validated at the University of Strathclyde, designed to deliver up to 60% more energy yield while reducing fixation and offshore construction costs. The group operates a fleet of specialized vessels including Tor Boreas (hybrid workboat) and Inyanga Entsha (DP2 multi-purpose vessel), plus a dedicated joint-venture interest in Tocardo with QED Naval.

The business model combines three revenue streams: long-dated CfD-backed power generation under 15-year UK government strike prices (currently 30MW secured at Morlais, Wales — the largest tidal energy project in the world once delivered), EPC and O&M contracts for third-party tidal developers (Verdant Morlais, Energies PH/San Bernardino in the Philippines, PLN Subholding in Indonesia), and offshore engineering consultancy plus vessel charter services. Pricing is not publicly disclosed but is anchored to the £198/MWh CfD strike price for AR5. Customers are predominantly government agencies (UK BEIS, Welsh Government, Menter Môn Morlais), state utilities (PLN), and offshore-wind support contractors.

The company has grown from UK-only to a multi-geography operator with wholly owned subsidiaries in France (Inyanga Tech, Rennes, 2021) and Canada (Inyanga Maritime Services Nova Scotia, Halifax, Dec 2024), and project engagements spanning Wales, Brittany, the Philippines, Indonesia, and Nova Scotia. Capital sources include the British Business Bank (cumulative £1.75M across four rounds), the Welsh Government (£2M equity plus £8M equity stake in Morlais), Crowdcube retail crowdfunding (Oct 2024), and business angels. Strategic partners include Hutchinson Engineering, RMSpumptools, Prysmian, Eire Composites, and the SHINES Interreg NWE consortium led by Fondation OPEN-C.

Revenue model

1. Tidal Energy Power Generation (CfD): Revenue from Contracts for Difference (CfD) government support scheme for tidal stream energy projects. Inyanga has been awarded 20MW (later expanded to 30MW) of CfD-backed tidal capacity at Morlais, providing guaranteed strike price for electricity generated over a 15-year contract period.
2. Engineering, Procurement, Construction & Installation (EPCI): Full EPC and installation services for tidal energy arrays delivered to third parties (e.g., Verdant Morlais 4.9MW project, Capul Philippines 1MW project). Includes long-term Operations & Maintenance contracts.
3. Vessel Charter (Tor Boreas): Charter revenue from operating the Tor Boreas hybrid work vessel for offshore wind support, ROV surveys, geotechnical surveys, diving operations, and marine construction. UTEC chartered the vessel in May 2026.
4. Offshore Engineering Consultancy: Inyanga Maritime division provides offshore operations and engineering consultancy for the marine renewables sector, including marine operations management, installation, and engineering services for third-party marine energy projects.

Others

• QED Naval: Scottish tidal turbine engineering firm and joint-venture partner with HydroWing in Tocardo. Related party via the Tocardo JV rather than direct competitor, but adjacent in marine hydrokinetic IP and project development.

Direct peers

• Nova Innovation: Edinburgh-based tidal stream developer operating the Shetland Tidal Array — the world's first grid-connected tidal array. Directly comparable as a UK SME targeting commercial-scale tidal deployment with government-backed offtake.
• SIMEC Atlantis Energy: Operator of the MeyGen tidal energy project in Scotland (the world's largest installed tidal array). Same UK tidal market with similar CfD-backed project economics; both companies compete for CfD allocation rounds and share offshore engineering service customer base.
• Verdant Power: US-based tidal stream developer (East River, Roosevelt Island project) and joint-venture partner with Inyanga at Morlais (Verdant Morlais Ltd, 4.9MW project). Direct peer and project collaborator.
• Orbital Marine Power: Scottish developer of the O2 floating tidal stream turbine (2MW), currently the world's most powerful operational tidal turbine. Most direct comparable in marine hydrokinetic energy, targeting similar utility-scale markets and CfD-backed commercialisation pathways in the UK.

Emerging players

• Minesto: Swedish developer of Deep Green tidal kite technology, targeting baseload renewable power from low-velocity tidal and ocean currents. Different technical approach (kite vs. fixed substructure) but competes in the same marine hydrokinetic space.
• Hydroquest: French developer of hydrokinetic turbines (Océade and Hydralocean platforms) with projects in France and overseas. Operates in the same French and EU markets as Inyanga Tech.
• Magallanes Renovables: Spanish developer of the Atir floating tidal platform, designed for deep-water tidal deployment. Comparable as a small-cap European tidal technology developer with utility-scale ambitions.

Broad incumbents

• Voith Hydro: Global large-hydro OEM and turbine manufacturer with marine energy technology programmes. Larger and more diversified than Inyanga but competes for the same utility-scale renewable baseload customers and policy support.
• ANDRITZ Hydro: Global large-hydro OEM with marine hydrokinetic R&D involvement. Much larger and broader portfolio; competes indirectly through conventional hydropower credibility and infrastructure scale rather than direct tidal stream competition.
