Tidal Transit Limited

Marine electrification specialist Tidal Transit has deployed Charge Qube, a battery energy storage system (BESS) from Fellten, to support onshore charging for e-Ginny, the company’s landmark retrofit electric crew transfer vessel (E-CTV).

This announcement marks a significant milestone for Tidal Transit as the company accelerates the transition away from diesel for offshore wind operations and maintenance fleets.

Charge Qube (CQ) is already utilised in sectors where instant, reliable access to power is critical, such as NHS Blood and Transplant, Automotive OEMs (BEV programmes) and EV fleet depots. The team also works closely with multiple emergency services, councils and a significant UK leasing company, all of which are using the CQ technology to address the persistent challenge of grid constraints.

Recognising a similar need for maritime as the sector quickly adopts electrification, the technology has now been repurposed for use in ports and docks where demand for high-power charging is rising faster than onshore grid infrastructure can support.

The Fellten range offers mobile battery energy storage solutions ranging from the CQ160 (160kWh) up to their planned flagship 1mWh. Tidal chose the CQ450 model, which deploys 450kWh of electricity storage in a mobile, modular battery system designed to be transported directly to where charging power is needed most. The system can be relocated to any shoreside location, offering ultra rapid charging up to 240kW to charge e-Ginny while docked.

The innovative and novel application for mobile energy storage is helping overcome one of the biggest barriers to marine electrification: a lack of sufficient grid capacity at portside locations. By introducing portable, containerised battery storage, Tidal Transit and Fellten  are helping bridge the gap in vessel charging infrastructure and supporting the wider shift to electrification across the commercial marine sector.

Leo Hambro, co-founder and CEO at Tidal Transit, commented: “One of the biggest challenges facing marine decarbonisation is that electric vessel technology is advancing faster than the supporting infrastructure onshore. If we’re serious about reduced fossil fuel dependence and decarbonising offshore wind logistics and wider maritime operations, we need practical charging solutions that work now, not years down the line.

“Fellten’s Charge Qube gives us exactly that. It provides the flexible, high-power system to support overnight charging capability we need for e-Ginny and other electric and hybrid vessels without being limited by local grid constraints. It’s a strong example of how smart, mobile infrastructure can help accelerate the transition to electric and move the wider marine industry closer to a zero-emission future.”

Mike Ellenthorpe, general manager at Fellten, added, “Tidal Transit’s e-Ginny is the perfect demonstration of what Charge Qube can enable: a real working vessel, operating in a demanding commercial environment and supported by flexible charging. We’re incredibly proud to support such a landmark project and believe e-Ginny will provide a powerful blueprint for the wider electrification of marine fleets.”

Tidal Transit’s e-Ginny project has seen the full transformation of a diesel-powered vessel, Ginny Louise, into a fully electric CTV, alongside development of critical offshore charging infrastructure. Combined with the new onshore charging solution from Fellten, Tidal Transit is accelerating progress towards electrifying offshore crew transport and reducing the operational carbon footprint of the offshore wind sector.
