This project is part of the Clean Maritime Demonstration Competition Round 4 (CMDC4) funded by the DfT and delivered by Innovate UK. CMDC4 is part of the Department’s UK Shipping Office for Reducing Emissions (UK SHORE) programme, a £206M initiative focused on developing the technology necessary to decarbonise the UK domestic maritime sector.

The grant will see Cemex and partners building a demonstrator of a smart shore power system with battery energy storage for vessels alongside. This system incorporates renewable energy to provide constant power whist simulating fluctuating power demands.

Following the success of initial paper-based feasibility studies, Cemex is working in partnership with University of Warwick and advanced system integrator, iconsys, to deliver an intelligently managed shore power system demonstrator, specifically tailored to understand self-discharging commercial vessel’s demanding electrical load fluctuations.

It will incorporate battery energy storage and solar photovoltaic energy generation, plus integrated hardware-in-the-loop simulation to both virtually expand the capability of the system and validate modelling software predictions.

The demonstrator will deliver constant power to the vessel alongside, after discharge at 250 kW, whilst simulating the full dynamic discharge cycle (1.5 MW) alongside the berth. The model enables the innovative, dynamic, multi-objective energy management system to maximise the use of lower-carbon electricity, minimising the use of engines alongside.

This stage of the project will take place at Cemex’s wharf in the Port of Shoreham on the Sussex coast. This will allow Cemex to manage the impact of the demonstrator on its operations. Additionally, it aligns with Shoreham Port’s wider sustainability goals and efforts to create a credible and measurable Local Industrial Decarbonisation Plan.

Work will start on this stage of the project in April, with 12 months allowed for installation and demonstration of the system to be completed and the results shared with stakeholders from the industry and the DfT.

Laurence Dagley, Operational Excellence and Business Development Director for Cemex West Europe materials, commented: “Our initial feasibility study for this shore power system identified an opportunity to save a significant amount of CO2 during each dredger discharge, while also improving local air quality at the port itself. We are therefore pleased to have received this funding to progress to the next stage of the project and undertake on-site demonstration.

“The timings for this stage are tight, but the potential benefits are considerable, as it will allow us to gain real experience of all the hardware, in a real environment, whilst being able to study full scale operation and quantify the benefits. Utilising the CEMEX GO INNOVATION, already the newest and most advanced aggregates dredger in the industry, this will be the first dredger in the UK to be shore powered and marks an exciting progression in our efforts to decarbonise.”

Jordan Tassell, Head of Marine & Ports for iconsys, commented: “This is a fantastic opportunity to progress towards a demonstration of the smart shore power system, a cutting-edge solution that goes beyond the standard. The aim is to offer key functionality and benefits that will support uptake within the maritime sector and drive the future of vessel connectivity.”

Dr Andrew McGordon, Reader in the Energy Applications Group at WMG, University of Warwick commented “This is a fantastic opportunity to demonstrate the learnings form the feasibility study using an innovative mix of real and virtual hardware, to understand the operational challenges of decarbonising this sector whilst developing state of the art energy management strategies to maximise CO2 emissions savings.”
