Investment value proposition
Developing an integrated marine-energy platform intended to combine multiple renewable resources, accessible maintenance and reduced reliance on permanent offshore infrastructure.
Market opportunity
The need for dependable marine renewable energy
Wave and tidal resources offer a substantial potential source of renewable electricity for countries with suitable coastlines, estuaries and river systems.
A commercially successful marine-energy technology would need to generate electricity reliably while achieving acceptable capital costs, operating costs, availability and environmental performance.
Pliosaur Energy is developing its technology in response to this opportunity, with the objective of contributing additional predictable renewable generation to future electricity systems.
Integrated technology
Harnessing wave and tidal resources
The Pliosaur Energy platform is designed to generate electricity from tidal streams, overtopping waves or both resources acting together.
Using a shared turbine for both forms of generation is intended to increase the range of energy available at suitable sites without requiring separate wave and tidal generating systems.
The ability to use more than one marine resource could improve generating opportunities and complement other renewable technologies whose output varies under different weather and tidal conditions.
Engineering economics
Designing to control project costs
The platform incorporates several features intended to simplify manufacturing, installation, operation and decommissioning.
These include a floating modular structure, recoverable deadweight anchors and an electrical architecture intended to reduce reliance on dynamic subsea export cables and extensive seabed trenching.
Floating components may also be assembled and maintained using established ports, shipyards and marine-engineering facilities, reducing the need for highly specialised offshore construction infrastructure.
The commercial objective is to determine whether these features can produce a competitive lifecycle cost of energy once the complete system has been tested and validated at increasing scale.
Lifecycle performance
More than initial construction cost
The economic performance of a marine-energy project depends on more than the cost of manufacturing and installing the turbines.
Long-term value will also depend on generating yield, reliability, availability, maintenance access, component life, grid arrangements, financing costs and the operating life of each project.
Pliosaur Energy's accessible floating configuration is intended to support inspection, maintenance and component replacement without requiring every intervention to be completed beneath the water.
These potential advantages will require confirmation through detailed engineering, physical testing and project-specific cost modelling.
Environmental considerations
Reducing impacts through design
The turbine incorporates a comparatively low rotor-blade tip speed and protective features intended to reduce potential interaction with fish and marine mammals.
Its floating architecture and recoverable anchoring system may also reduce the need for piling, permanent foundations and extensive disturbance of the seabed.
The semi-submersible structure is intended to have a relatively low visual profile when viewed from surrounding coastlines.
The effectiveness of these measures must be assessed through site-specific environmental studies, consultation, monitoring and regulatory review.
Deployment potential
Application across suitable marine locations
The technology is intended for deployment in suitable coastal, estuarine and offshore locations with appropriate wave or tidal resources.
Its shallow-water capability could create opportunities at sites that may not be suitable for deeper-draught offshore technologies, while the floating configuration may also support deployment in deeper water.
Regions such as the Bristol Channel, the English Channel and the west coast of Scotland illustrate the types of marine environments that may warrant further assessment.
No location can be considered suitable until resource, bathymetric, environmental, navigational, grid, planning and commercial studies have been completed.
Strategic value
A differentiated development proposition
Pliosaur Energy's value proposition brings together several potential advantages within one platform:
- generation from wave and tidal resources through a shared turbine system;
- a modular floating structure intended to support phased deployment;
- recoverable mooring and anchoring components;
- accessible equipment intended to simplify maintenance;
- reduced reliance on permanent seabed infrastructure;
- the potential to intercept floating marine debris; and
- opportunities to use established shipbuilding, port and offshore-engineering capabilities.
The commercial significance of these features will depend on successful technical validation and their ability to deliver measurable benefits within real projects.
Important information
Pliosaur Energy remains a development-stage technology company. Its integrated commercial-scale system has not yet been fully constructed, deployed or validated in an operational marine-energy project.
Statements concerning future generating performance, cost reductions, environmental benefits, project locations, deployment scale and commercial competitiveness are objectives and expectations rather than guaranteed outcomes.
Actual performance will depend on engineering results, site conditions, consenting, supply-chain capability, grid access, financing and other technical and commercial factors.
