Vessels and terminals face energy questions that arrive from four directions at once. Regulation. Fuel availability along the trade. Grid capacity at the quay. Competitive position across the market. Nexus Energy treats the ship, the terminal and the infrastructure between them as one system. Measured, modelled, engineered, delivered.
Ships and terminals get the same fragmentation problem in two shapes, and it is about to sharpen fast.
A ship today makes an energy decision under pressure. Fuel prices, retrofit choices, emission rules, and windows of technology maturity, all arriving at the same time. Each piece lands on a different desk. Each piece gets a different consultant. The pieces do not add up to a system that lives inside the trade the vessel actually runs.
A terminal today faces the same fragmentation with an added time bomb. Trucks are electrifying. Every container that arrives and leaves will eventually roll in on an electric tractor that wants to fast-charge before it moves. That is not one charger at the gate. That is a dense grid of high-power charging alongside the terminal's own electrifying processes: cranes, reach stackers, shore power at the quay, cooled containers, the office block. Every one of these arrives on its own timeline and its own budget line.
Three questions get asked at once, and rarely by the same people. How does this fit together technically, given the physical grid connection and the balance of loads across the day. How does it stack up financially and economically across a twenty-year investment horizon, while the next five years remain deeply uncertain in revenue model and technology maturity. And what does the terminal do with certificate value: how it is generated, how it is booked, how it is traded, and what happens when the schemes shift underneath it.
The framing is the failure. A solution engineered against the wrong reality is not a solution. A portfolio of solutions that do not talk to each other is not a strategy.
Nexus Energy works from four knowledge pillars, none subordinate. Each is a discipline. Together they produce a defensible answer whatever the input, on ship or terminal side.
Onboard energy conversion, storage and generation at subsystem level. Terminal-side infrastructure. Technology-agnostic across carriers and conversion routes.
AFIR, FuelEU Maritime, EU ETS, IMO Net-Zero Framework, RED III, CSRD and national schemes. What binds when. What is optional. Where the certificate value sits.
A plan that is executable technically, economically and financially. Not only on day one, but at the far end of a twenty-year investment horizon in which revenue models, technology maturity and certificate markets will all shift. Sensitivities and scenarios sit in the case, not behind it.
Hands-on at the micro level: what actually happens on board, in the machine room, at the switchboard, on the quay. Duty cycles under real load. Integration behaviour under commissioning. The detail that determines whether a design survives its first year in service.
One method, from first measurement to running system. It is the same method whether the asset is an inland dredger, a crew transfer vessel or a full container terminal. The technology under evaluation changes. The method does not.
Real operational data first. Not datasheets, not typical values, not simulated profiles. What the asset actually does, on the trade it actually runs.
For a vessel: where it trades, what fuels and charging are available along that trade, what binds on those routes. For a terminal: the grid headroom, the site plan around it, the competing loads on the same connection. Externally-dictated constraints that any solution must live inside.
Energy architecture built on measured behaviour and real constraints. Options laid out with their trade-offs. Certificate strategy positioned across the schemes that apply.
FEED conclusion, defensible. Go, no-go, or refined scope, together with a phased investment path substantiated against sensitivities: fuel prices, certificate value, technology maturity. The client walks away with a decision they can defend to a board, a financier and, later, an auditor.
When the case sustains, EPIC follows. System architecture, detail engineering, procurement, class engagement, installation, commissioning, monitoring.
Any step can conclude that the next step is not warranted. Advising liquid hydrogen to a vessel whose trade has no liquid hydrogen supply is not advice. It is wasted FEED time. The check happens at step 02, not at handover.
Delivered work across vessel-side, terminal-side and the interface where they meet. Operational deployments alongside a portfolio of FEED studies covering distinct vessel types and decision contexts.
Nexus Energy supplied a hydrogen fuel cell PowerPack alongside two battery containers for Van Oord's fully electric dredging pilot in Dordrecht, January 2025. Combined system delivered the vessel's full operational power without limits, across live dredging days and nights.
Ten weeks of continuous zero-emission shore-power delivery to a supply vessel alongside a quay in Rotterdam. Silence at the quay, no local emissions, and operational proof of an LTPEM fuel cell system running uninterrupted for the full duration.
Inland dredger toward hydrogen-electric. Crew transfer vessel hybrid performance diagnosis. Supply vessel retrofit versus hybrid decision. Different vessel types, different decision contexts, one repeatable method.
The integrated system, made visible in one narrative arc.
A terminal today runs seven separate energy interactions with the outside world. Diesel equipment in the yard. Diesel lorries at the gate. Vessels running their own generators at berth. A grid connection that powers only lighting, cranes and offices.
Between now and 2035, each of these can shift. If they shift together, in the right sequence, under one plan, the terminal becomes an active participant in the energy system, not a passive consumer of it. It produces. It stores. It balances. It exports when the market rewards flexibility. It captures certificate value across schemes. The same shift happens on the vessel side, when a fleet decision is planned as a system rather than a fuel choice.
The ship. The terminal. The infrastructure between them. One energy system, not a stack of separate projects. Nexus Energy treats all three as such.
For a vessel: the routes it runs, the ports it calls, the fuels available at each stop, the regulatory zones it crosses, the schemes on which its energy can be credited. For a terminal: the grid connection headroom, the load profiles across the year, the demands competing for shared capacity, the certificate schemes where value flows in or out. The real context, before any technology conversation.
Business case built on that real data. Certificate strategy positioned across schemes and geographies. Delivery through FEED and full EPIC when the case sustains.
That is the difference.
The first conversation is exploratory.
No prepared deck required. Bring the question you are sitting on: a vessel retrofit decision, a shore-power case, a certificate strategy, an investment roadmap for a whole site or fleet that has to hold up across a twenty-year horizon of shifting revenue models and technology maturity.
We respond with what we would measure first, what the operational context adds to the picture, and what the answer would have to show before we commit to it. Direct and technical. No sales pitch.
