Welcome to SEAWORTHY: Revolutionizing Offshore Power with Clean Energy
SEAWORTHY is a groundbreaking commercial-scale project that introduces a first-of-a-kind technology capable of delivering clean and dispatchable offshore power through a harmonious blend of wind, waves, and hydrogen (H2). This project serves as a pivotal demonstration, setting the stage for the widespread adoption of this transformative technology in the offshore Power-to-X market. By providing clean and cost-effective dispatchable power, SEAWORTHY addresses the energy needs of offshore, off-grid, and coastal weak-grid applications, such as islands, that currently rely on fossil fuels.
SEAWORTHY is short for Sustainable dispatchable Energy enabled by wAve-Wind OffshoRe plaTforms with onboard HYdrogen.
Key Components of SEAWORTHY: P-Demo
Our demonstrator technology, P-Demo, integrates a 4.3 MW Wind Turbine Generator (WTG), a 0.8 MW Wave Energy Converter (WEC) system, and a hydrogen system comprising a 1 MW electrolyzer, 48 MWh of energy storage, and a 1.2 MW fuel cell. P-Demo is set to become the world’s first wind-wave-hydrogen unit, and it will be deployed at PLOCAN’s test site in Spain. This innovative system is projected to deliver 11.05 Gigawatt hours (GWh) per year of renewable electricity to the grid, avoiding a total of 25,557 tonnes of CO2 equivalent during its first 10 years of operation, with a remarkable 100% relative greenhouse gas (GHG) emission avoidance.
Key Features and Benefits
SEAWORTHY’s innovative features maximize the utilization of wind and wave resources, enhancing power quality, increasing output capacity per unit, and ensuring consistency over time. The integration of hydrogen production systems, including electrolysers, along with higher energy storage capacity (up to 300 MWh) and fuel cells, facilitates the provision of truly dispatchable renewable power.
This unique combination minimizes the total investment per megawatt by leveraging shared infrastructure (mooring, platform, and grid infrastructure) for the three technologies within a single unit. Additionally, SEAWORTHY incorporates manufacturing materials and techniques from the shipbuilding value chain, enabling scaled series production and economies of scale.
Contributions to Policy Priorities
SEAWORTHY aligns directly with the EU Strategy on Offshore Renewable Energy and contributes to long-term climate neutrality objectives. Recognizing the pivotal role of energy storage, the project supports REPowerEU’s goal of ending external dependence on fossil fuels, ensuring the security of supply, and facilitating renewables integration.
Beyond its technological advancements, SEAWORTHY offers various manufacturing and assembly options, supporting the use of different facility types and a distributed European supply chain. This approach creates opportunities for high local content and job creation, even in areas lacking a strong marine industry, gradually scaling a suitable value chain.
Join us in reshaping the future of offshore power with SEAWORTHY—a testament to innovation, sustainability, and a cleaner energy landscape.
