About H-WEC and OWC

Havkraft Wave Energy Converter (H-WEC)

Havkraft Wave Energy Converter (H-WEC) is a Norwegian-developed technology designed to extract energy from ocean waves. The solution is based on extensive experience from the offshore and maritime industry and is designed to deliver renewable power in a robust and scalable manner.

H-WEC utilizes the OWC technology where the movements of the ocean is creating water pistons that in turn generate a pulsating pressure that drives turbines and generators. The technology is integrated into a modular concept that can be used in various applications, both as a standalone energy producer and in combination with other renewable energy sources.

What we do

Advantages of H-WEC

  • Clean energy: Utilizes the natural power of the sea, completely without emissions.
  • Modular and scalable: Can be tailored to the customer's needs reflected in the number of chambers.
  • Robust technology: Developed with consideration for challenging conditions along the Norwegian coast.
  • Predictable production: Wave power has a more stable production profile than wind and solar in many areas.
  • Placement close to demand: Can supply electricity to oil and gas facilities, operational rigs, fish farming facilities, or increase production from wind farms.
  • Compatible with hybrid solutions: Can be combined with solar, wind, and batteries to provide a balanced energy supply.

Challenges of H-WEC

  • Technological maturity: In a development phase and not yet fully certified and commercially available.
  • Costs: Investment costs per installed MW are difficult to provide answers to before a full-scale plant is built.
  • Operating environment: The sea is demanding, and equipment must withstand salt, waves, and storms over a long period.
  • Grid integration: Effective connection to land grids or local use often requires additional infrastructure.
  • Regulation and standardization: Certification and approval of new solutions can take time.

Our approach to the challenges: To ensure that H-WEC becomes a competitive technology, we are actively working to meet the challenges: Technological maturity: We conduct systematic tests and demonstration projects at various scales to document performance and reliability. Cost reduction: We collaborate with industry partners to develop efficient production methods and optimize the design for mass production. Operational robustness: We draw experience from the offshore industry and develop solutions with high longevity, easy maintenance access, and the use of corrosion-resistant materials. Regulation and certification: When design freeze happens, we will intensify our effort together with DNV to ensure that the technology meets international requirements and can be quickly adopted in the market.
