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.

Key Benefits

Advantages of H-WEC

Clean energy: Utilizes the natural power of the sea, completely without emissions.
Modular and scalable: Converters can be adapted 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.

Considerations

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.
Operating 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.

Our Standards

Quality through Testing and Certification

At Havkraft, we know that trust is built on quality. That’s why we thoroughly test and qualify our technology to ensure it performs as expected in real-world conditions.

Some parts of our system are proven standard components, while others are developed specifically for our solutions. All components will be assembled and tested over time to document performance, reliability, and robustness.

We follow relevant standards and requirements throughout the process, and we have a certification process ongoing with DNV.

2026/2027: Havkraft’s will carry out a TRL6 qualification test.
2027/2028: Full-scale Test (TRL 7) : 1:1 model
