Aqua Superpower has begun its Virtual Bunkering for Electric Vessels (VBEV) demonstration, reportedly marking the world’s first vessel-to-grid project.
Virtual Bunkering for Electric Vessels (VBEV) project
The VBEV project is intended to demonstrate the opportunity for bidirectional (V2X) infrastructure to use marine batteries to provide energy storage and management services to harbors, ports and the grid, minimizing costly grid upgrades, reducing energy bills and increasing renewables integration.
This project leverages the previous Clean Maritime Demonstration Competition 2 (CMDC2) feasibility study, showcasing how electric vessel batteries can provide energy storage and flexibility services to harbors, ports and the grid when the boat is not in use.
Funding
The project has been funded by the £206m (US$262m) UK Shipping Office for Reducing Emissions (UK SHORE) domestic maritime program and delivered through Innovate UK. This is because it won the Clean Maritime Demonstration Competition (CMDC) Round 4 (CMDC4).
Technology deployed
The VBEV project introduces software upgrades, communication protocol adoption and charge controllers into electric vessels. This integration enables communication between batteries and bidirectional chargers, laying the foundation for a vessel-to-grid management platform. This platform empowers optimal charge and discharge scheduling, maximizing energy efficiency.
Methodology
VBEV will test two pivotal scenarios: vessel-to-grid, exporting energy to the grid for flexibility and balancing services, and a behind-the-meter solution for enhanced on-site energy management. These scenarios cater to the diverse needs of ports, harbors, vessel operators and grid network operators.
Motivation
The UK, with 255,484 recreational/commercial vessels under 12m, is set to transition to zero-emission operations over the next decade. According to British Marine, an additional 10,000 vessels join the fleet annually, presenting a massive electrification opportunity. These vessels, with the potential for electrification, will necessitate port/harbor/marina charging solutions. The VBEV project identifies an opportunity for bidirectional charging and virtual bunkering of electricity, not only advancing decarbonization but also meeting immediate infrastructure and grid demands.
Feasibility shows potential for electric vessels to offset all carbon associated with charging. The four-week demonstrator will illustrate how all key infrastructure, software, vessel and energy components interact. Two vessels will be connected to bidirectional chargers, showcasing energy sent to the grid and adept energy management behind the meter.
Intended applications
With the electric vessel industry on the rise, this initiative hopes to create a scalable future with benefits ranging from improved battery health to reduced operational costs and revenue generation. VBEV plans to produce the first vessels capable of bidirectional power transfer, set a standard for other vessel manufacturers, develop a vessel-to-grid management platform, and provide world-leading research and development of a commercial product for customers.
Aqua Superpower consortium
Aqua Superpower heads a consortium that brings together representatives from marine infrastructure, vessel manufacturing, software and energy. This includes two vessel OEMs (RS Electric and Ingenity), energy company EDF, the University of Plymouth, City College of Plymouth, research center CENEX, and bidirectional software provider Fuuse. According to Aqua Superpower, this collaboration ensures a holistic approach to advancing vessel-to-grid capabilities.
Alex Bamberg, CEO of Aqua Superpower, stated, “Enhanced energy management will allow sites to better adapt to increasing demands on power from electrification of vessels, potentially reduce the grid connection where capacity is limited or costly and integrate more renewables. We are proud to lead this vital project that demonstrates Aqua Superpower first-class marine charging expertise and positions the UK as a vessel-to-grid technology pioneer.”
Jon Partridge, CEO of RS Marine Group, added, “RS Electric Boats is thrilled to participate in the VBEV trials, demonstrating vessel-to-grid technology. We believe this innovation will significantly reduce ownership costs and lower the barriers to zero-emission transition. Importantly, our Pulse 63 will set a precedent as the first production electric boat equipped with V2G capabilities. This milestone not only underscores our commitment to sustainable maritime innovation but also represents a significant leap forward in the electrification of the marine sector.”
Dr Will Maden, co-founder and chief operating officer (COO) of Fuuse, said, “This project represents a fundamental step in bringing electric boats to the market. The current usage and duty cycles of certain target vessels mean that there are substantial benefits to the operating costs of the vessel and potentially to the local and national electric infrastructure. Fuuse will bring its extensive knowledge of automotive V2X technology to the marine setting, embedding protocols and service processes early in the development phase. This strategic integration aims to optimize efficiency and reliability, transforming how energy is managed and utilized in maritime transport, thereby contributing significantly to sustainability and economic savings in the sector.”
Patrick Dupeyrat, R&D director at EDF UK, commented, “Energy flexibility is expected to play a key role in ports/harbors, as the need for electrification grows. EDF is delighted to work alongside partners in this vessel-to-grid demonstration project, providing expertise on flexibility markets and a commercial pathway for V2X for vessel owners. EDF will also assess the opportunity for the integration of renewables at ports/harbors to address grid constraints and outline the role of V2X in port-wide microgrids.”
Dr Lee Durndell, lecturer in chemistry at the University of Plymouth, explained, “This project is another important step in the UK’s transition to clean maritime technologies. There is clear appetite from both vessel and harbor owners to see the sector grow over the coming years, but technical questions remain that need to be answered. One of those is around battery performance and health, and this project will begin addressing that while aligning with the growing commercial interest in clean maritime and how it can be rolled out more widely.”
Greg Payne, principal technical specialist at Cenex, highlighted, “By evaluating additional marine archetypes with real-world duty cycle data, we will help to provide clear direction for the implementation of V2G technology for the marine sector. We will also seek to provide clarity on required standards and their implementation.”
Lance Chatfield MBA MSET, executive of technical innovation at City College Plymouth, enthused, “City College Plymouth is delighted to be involved in this incredible, innovative project. To meet the current and future demand for expertise in the blue (marine) and green (renewable) sectors of industry, we intend to build an accredited college course based on the design, installation and maintenance of marine charging systems and V2X. This demonstration sits perfectly in between these important agendas concerning the future of our oceans, energy and economy.”
Capt. Todd Sims, business development director of Ingenity, concluded, “As a manufacturer of high-power recreational electric boats and propulsion systems, Ingenity is excited to be a part of this team to demonstrate the benefits of V2X in an impactful and practical setting. We have customers with boats around the world and look forward to being able to offer this additional benefit of ownership sometime very soon. Adding value to our products is something we continuously strive for, and delivering on V2X functionality is certainly worth the effort.”
In related news, marine fast charge network operator Aqua Superpower recently joined the ZENOW technical partnership (Zero Emissions Network of Workboats), which received £4.1m in grant funding from the UK Shipping Office for Reducing Emissions (UK SHORE) and Innovate UK as part of the Zero Emissions Vessels and Infrastructure (ZEVI) competition.
