How the collaboration will work
When ships are in port, they typically use onboard diesel generators to power vessel operations. Globally, this results in around 35Mt of CO2e generated per year. With many ports located close to population centres, pollution concentrations have major impacts on local communities. This project aims to validate a novel, highly efficient and low-cost cold ironing solution to provide clean, shoreside power as an alternative to onbaord diesel generators.
The end-to-end system starts with a Solar PV system, hosted by Cranfield University. This provides power directly to the vessel when at birth. However, during periods where supply exceeds demand, electricity is fed into a high-efficiency power management architecture provided by project partner HyWaves to power an electrolyser producing green hydrogen. HyWaves’ technology simplifies the architecture needed to operate and produce green hydrogen from solar power, delivering both an efficiency improvement and cost reduction.
Hydrogen is stored using low-cost, high-density technology from Rux Energy. This stage is critical in providing long-term, cost-effective energy storage, managing seasonal and operational variations.
High efficiency Carnot engines will then use the hydrogen fuel to provide on demand power. Shoreside generators will be connected to vessels whilst moored in port. Clean Air Power, a supplier of specialist injectors and valves for alternative fuels, will provide High Pressure Hydrogen Injection (HPHITM) technology to control the flow of hydrogen into the Carnot engine. The Manufacturing Technology Centre, the UK’s centre of excellence for manufacturing technologies, is providing expertise guiding the path to engine development and providing design for manufacture insight, optimised for additive manufacturing processes. This will then be tested at Brunel University, London. Throughout this phase, Carisbrooke Shipping will provide the critical insight from a vessel operators perspective, including implications on regulations and operational requirements.
The project revolves around Freeport East, assisting with outreach and engagement with other ports operators, shipping lines and the trust port, Harwich Haven Authority.
Swanbarton and Brunel University are collaborating to develop the Energy Vector Analyser (EVA). EVA will help ports understand their current energy landscape and facilitate future planning. By evaluating a wide range of potential fuel, generation, and storage options, EVA seeks to minimise investment risks associated with unviable or obsolete technologies, thus avoiding stranded assets. This tool will enable ports to identify viable aspects of the hydrogen lifecycle within their full energy system enabling informed investment and ensuring they can offer future services like shore power, despite existing infrastructure and geographical constraints.
