InfinityWEC is a novel point absorbing Wave Energy Converter (WEC). It is both highly efficient in capturing energy through its ability to adjust to the sea state, and robust enough to operate reliably and survive the harshest marine conditions. Cost efficiency is further improved by its modular design and the easy handling, allowing for road transportation and requiring a minimum of offshore operations.
InfinityWEC uses advanced reactive force control technology to tune the system to capture the optimal amount of energy in every wave, which greatly increase the annual output. A two-stage end-stop handling system holds the buoy submerged through the crest of large waves and then returns the system to normal operation, protecting the system from excessive forces and allowing energy to be produced even in the most severe wave conditions.
The system is installable with a minimum of complicated offshore operations and no diving or heavy lifting are necessary offshore.
The InfinityWEC technology and design is patent pending and developed by Ocean Harvesting Technologies AB in collaboration with experienced partners.
Advanced reactive force control on the buoy is provided throughout the full wave motion, which greatly amplifies the energy output and minimizes cost by limiting loads.
Direct drive ball screw actuators in combination with a hydraulic pre-tension spring system provide highly efficient PTO force control capability at a low cost.
InfinityWEC does not have a survival mode where power production is shut down in strong sea states, instead it uses a passive survival strategy allowing power to be produced in every wave.
A novel two-stage end stop cushion system holds the buoy submerged through the crest of large waves.
Solving the challenges of wave energy
Our technology has the potential for cost effective electricity generation to main power grids, as well as to off-grid applications.
We follow the staged development method set out by the international marine energy community
OHT is since 2017 developing the novel InfinityWEC wave energy converter with advanced force control and with AI capabilities. We have an extensive know-how in the wave power application and patent protection covering all aspects of the InfinityWEC system. To mature the concept we have developed tools to accurately assess dependencies between design and the overall life cycle cost of the system. We believe in using numerical models to time and cost efficiently simulate the behavior, loads and performance of the system, and to verify them with limited and controllable physical tests. This ensures we are on track to a commercially viable system before we move into large scale prototypes and testing.
We are currently in the design and validation phase of the InfinityWEC technology, building a scale 1:10 of the InfinityWEC power take-off system, to be tested in a hardware-In-the-loop (HIL) test rig. This enables us to simulate authentic load conditions in a controlled dry environment.
In 2022 we plan to conduct sea trials with a fully operational InfinityWEC in approximately scale 1:3.
In 2024 we plan for sea trials with a full scale 500kW InfinityWEC after which our system is validated and certified.
In 2025 we plan for our first commercial installations.
