Predictable output
Marine currents can be forecast years in advance, supporting grid planning and bankability.
Floating tidal energy
Predictable electricity from marine currents
BlueNRG designs a floating vertical-axis tidal turbine to convert marine currents into decarbonized, predictable and competitive electricity.
The technology targets a record 4 MW unit power, with a robust design-to-cost architecture built to reduce CAPEX, simplify offshore operations and keep electromechanical components accessible at sea level.

Tidal energy has high system value
Energy systems are under pressure. Electrification, industrial demand and security of supply make sovereign and independent low-carbon electricity increasingly necessary. Tidal stream energy is predictable, independent from weather and complementary to solar and wind.
Solar / wind complement
Tidal generation follows a different production profile from solar and wind and helps reduce system stress.
Sovereign electricity
Local marine resources can strengthen independent, low-carbon electricity production for coastal countries.
System value
Predictability reduces dependence on firming resources and increases the value of each MWh produced.
Technology
A floating vertical-axis architecture designed for scale
BlueNRG develops a modular floating tidal turbine. The vertical-axis architecture is designed to increase unit power, simplify installation and maintenance, remain robust offshore and reduce CAPEX from the design stage.
Floating tidal turbine
A floating structure positioned at sea level, with turbines operating below the surface where marine currents are captured.
Vertical axis and multi-stage turbines
A modular vertical-axis architecture with multi-stage turbines, independent from current direction and adaptable to site depth.
Sea-level access
Electromechanical components are designed to remain accessible at sea level, simplifying inspection and maintenance.
Design to cost
Architecture, installation and operations are designed from the start to be robust and reduce CAPEX and OPEX.
Competitiveness
Record power and lower CAPEX must work together
A robust design-to-cost architecture, combined with a record 4 MW target unit power, is intended to reduce CAPEX and reach the most competitive electricity costs in tidal stream energy. The objective is not only technical performance, but a bankable renewable energy product.
Market
A European market entering a structured phase
France and the United Kingdom are two priority markets for tidal stream energy. The timing is driven by energy sovereignty, rising electricity needs and the need for predictable renewable generation.
250 MW under the PPE framework
The French PPE includes a first 250 MW commercial tidal tender at Raz-Blanchard, with a target award by 2030. Several additional 250 MW sites are already being considered.
CfD framework for tidal stream
The UK market benefits from Contracts for Difference allocation rounds dedicated to tidal stream energy, with dedicated support mechanisms depending on auction results and project eligibility.
Demonstrator
A first offshore demonstrator before commercial scale
BlueNRG is preparing a first offshore demonstrator in real operating conditions. Site options are under review in France and in the UK. The objective is to validate the design, offshore operations, performance and certification pathway before moving to the 4 MW commercial range.
