Win UK Clean Maritime Feasibility Study Funding: How to Secure a Share of £121 Million in the Innovate UK Clean Maritime Demonstration Competition 7 Grant

If you build maritime tech, you already know the problem: ships are enormous, complicated machines that spend their lives in punishing conditions, under tight regulations, and inside supply chains that don’t tolerate “maybe it’ll work.” Innovation is welcome—right up until it risks downtime, safety incidents, or missed schedules. Which is exactly why feasibility funding matters.

The Clean Maritime Demonstration Competition 7 (CMDC7) is one of those rare funding calls that actually matches the scale of the challenge. The UK is putting serious money on the table—up to £121 million across three strands—to push clean maritime technologies from “good idea” to “credible plan.” This particular strand focuses on feasibility studies, meaning it’s designed to help you prove technical and commercial viability before you start cutting metal or booking sea trials.

And let’s be honest: feasibility work is the unglamorous hero of maritime progress. It’s the spreadsheets, the simulation models, the risk registers, the supply-chain calls, the class and regulatory reality checks. It’s the stage where you find out whether your decarbonisation concept is a speedboat or an anchor.

If you’re a UK-registered business with a strong consortium behind you, this competition is a big deal—and a tough one. But it’s absolutely worth the effort if you can tell a clear story about impact, deliverability, and why your approach can thrive in the real-world maritime environment.

What this opportunity offers (and why feasibility money is gold)

Feasibility studies don’t get the glory, but they get you to the glory. This strand is designed to pay for the thinking-work that turns an exciting technology into something investors, shipowners, ports, and regulators can take seriously.

In practice, feasibility funding can support activities like: engineering studies, system architecture design, modelling and simulation, early-stage safety and hazard assessments, integration planning (because maritime tech rarely works in isolation), supply-chain viability checks, and commercial validation with real end users. It’s where you prove not just that your idea could work, but that it can survive marine environments, maintenance cycles, and operational constraints.

Just as importantly, feasibility work is where you figure out your “route to water.” Maritime innovation dies when it can’t answer basic questions: How will it be installed? Who will maintain it? What happens when it fails? What regulations apply? What does class say? How does this affect turnaround time in port? A strong feasibility study tackles these head-on, rather than hoping everyone will stop asking.

The bigger prize here is momentum. A well-run feasibility project can set you up for the next funding stage, private investment, customer pilots, or a demonstration project. Think of it as building the evidence pack that makes later-scale funding much easier to win. You’re not just researching—you’re reducing uncertainty for everyone who might back you later.

Who should apply (and who should not): eligibility explained with real examples

This competition is collaboration-only, and that’s not a polite suggestion. It’s the whole point. Clean maritime innovation requires multiple players—technology developers, integrators, vessel operators, ports, shipyards, universities, class/regulatory expertise, and often energy infrastructure partners. If you’re trying to apply solo, this isn’t your call.

To lead the project, your organisation must be a UK registered business of any size. Startups are welcome. So are established marine engineering firms. The key is that the lead must be a business, and the project must include collaboration with other UK registered organisations.

Here are a few examples of teams that fit this competition well:

A UK startup developing a novel energy storage system partners with a UK shipowner (to validate operational needs), a UK naval architect (for integration and stability impacts), and a UK university lab (for modelling and safety analysis). The feasibility study produces a credible plan for a pilot installation.

A UK maritime digital company building route optimisation software partners with a UK port operator and a UK vessel operator to test data availability, cyber/security requirements, and practical adoption barriers. The feasibility work shows measurable fuel/emissions impact and a plan for a demonstration trial.

A UK engineering SME exploring retrofit solutions for alternative fuels partners with a UK shipyard and a UK training provider to evaluate installation timelines, workforce needs, and maintenance implications. The feasibility study becomes a blueprint for a demonstrator.

Who should probably sit this one out? Anyone who can’t get meaningful collaborators onboard, or anyone with a concept that’s still at “napkin sketch” stage with no credible path to maritime deployment. Feasibility doesn’t mean “vibes.” You’ll need substance—partners who will show up, data you can access, and a plan you can execute.

Understanding the collaboration rule (and how to build a consortium that works)

A collaboration can be your superpower or your downfall. The best consortia aren’t the biggest—they’re the most functional.

Your goal is to assemble partners who contribute distinct value:

A user partner who can validate real operational constraints (shipowner/operator, port, logistics company).

A technical partner who strengthens delivery (engineering firm, integrator, shipyard, OEM).

A knowledge partner who boosts credibility (university, research organisation, specialist consultancy).

A supply-chain or infrastructure partner if your tech depends on it (fuel providers, shore power operators, charging or bunkering infrastructure players).

Make sure every partner has a defined role and a reason to care. If a partner joins just to “be on it,” reviewers can tell. And nothing slows a feasibility project like partners who won’t provide data, won’t attend technical sessions, or disappear when it’s time to sign off outputs.

Insider tips for a winning application (the stuff reviewers quietly reward)

You asked for practical advice—here it is, with the blunt honesty that saves you weeks.

1) Treat feasibility like a detective story, not a marketing brochure

Your application should read like a careful investigation: here’s the hypothesis, here’s what we’ll test, here’s the evidence we’ll gather, and here’s what we’ll conclude. If your write-up sounds like a sales pitch, you’ll look unready for real-world maritime complexity.

2) Name the blockers you expect—and explain how you will de-risk them

Maritime is full of “yes, but…” moments: yes, but the vessel can’t spare space; yes, but power quality is an issue; yes, but class approvals; yes, but port dwell time. Strong applications don’t pretend these problems don’t exist. They identify them early, rank them by severity, and propose a plan to reduce them during the study.

3) Make your end-user involvement specific and visible

If you have a vessel operator or port in the consortium, show exactly what they’ll do. Will they provide operational data? Host workshops? Validate scenarios? Review the business case? If the end user’s role is vague, reviewers will assume it’s window dressing.

4) Build outputs that clearly lead to the next step

Feasibility projects win when the outputs are actionable. Think: a technical feasibility report is fine, but a feasibility report plus an integration plan, risk register, regulatory pathway outline, cost model, and a draft demo plan is much better. Reviewers love a project that ends with “we are ready to demonstrate.”

5) Quantify your emissions impact in a way a sceptic can respect

You don’t need perfect numbers, but you do need a defensible method. State your baseline (what you’re replacing), define your operating profile assumptions, and show how your technology changes fuel burn or emissions. If you can, include multiple scenarios (best case, expected case, conservative case). It signals seriousness.

6) Put project management on the page, not just in someone’s head

Feasibility sounds simple until schedules slip and partners stall. Spell out how you’ll run the project: decision points, review meetings, milestones, quality checks, and how you’ll handle changes. A tight plan is comforting—especially in a collaboration.

7) Use plain English for technical concepts (without dumbing anything down)

Reviewers want clarity. If you’re proposing something complex—hybrid propulsion architectures, hydrogen storage constraints, ammonia safety considerations, shore power interface limits—explain it like you would to a smart operations director who doesn’t have time for jargon.

Application timeline: a realistic plan working back from 15 July 2026

The deadline is 15 July 2026 at 11:00. That sounds far away until you remember you’re coordinating multiple organisations, costs, work packages, and approvals. A sensible approach is to work backwards and give yourself buffer time for partner sign-off and internal reviews.

Aim to have your consortium agreed in principle 12–16 weeks before the deadline. That’s when you should lock roles, confirm who provides what data, and agree what “success” means. If you wait until the last month to recruit partners, you’ll end up with a shaky consortium and a rushed narrative.

By 8–10 weeks out, you should have a draft project plan: objectives, tasks, milestones, and outputs. This is also the right time to start shaping your impact story—who benefits, how adoption happens, and what your path to demonstration looks like.

At 4–6 weeks out, shift from planning to polishing. Write the application in full, circulate it, and invite criticism. Not compliments—criticism. Ask partners to sanity-check claims, costs, timelines, and responsibilities.

In the final 2 weeks, focus on compliance and coherence. Make sure every promise in the narrative appears in the work plan, and every work plan item has a clear owner. Plan to submit at least 48 hours early. Systems get busy, people go on leave, and nothing good happens at 10:57 on deadline day.

Required materials: what you will likely need and how to prepare it

The listing directs applicants to the Innovation Funding Service, where the detailed requirements live. While the exact set of forms can vary by Innovate UK competition, you should expect to prepare a package that covers your project story, your team, and your finances.

In practical terms, plan time to assemble:

• A clear project description: the problem, your solution, what the feasibility study will do, and what outputs you’ll deliver.
• A structured work plan with tasks, milestones, and partner responsibilities.
• A realistic budget broken down by partner, with costs that make sense for feasibility work (people, modelling, subcontracting, workshops, travel, etc.).
• Evidence of a credible consortium: who the partners are, why they’re essential, and how they’ll contribute.
• A defensible impact case: emissions reductions, operational benefits, adoption pathway, and future scaling.

Preparation advice: start with a one-page “consortium brief” that summarises the concept, roles, and expected contributions. Send it to partners early. It prevents weeks of confusion and saves you from rewriting the same explanations in ten email threads.

What makes an application stand out: how reviewers tend to think

Reviewers generally ask three big questions—sometimes explicitly, sometimes between the lines.

First: Is this important and timely? Clean maritime isn’t a niche hobby anymore. But you still need to show why your specific tech matters: what emissions source it targets, what vessel types it fits, and why now is the moment.

Second: Is this credible as a feasibility study? Feasibility isn’t “we’ll brainstorm.” It’s a structured plan to answer real uncertainties. Strong applications name the uncertainties, design activities to test them, and define decision points (“If X fails, we pivot to Y” or “If Z is not viable, we stop and report honestly”).

Third: Can this team deliver? Collaboration-only calls reward teams that have done their homework. A consortium with a clear lead, committed partners, and access to operational data looks dramatically more credible than a group of organisations connected only by enthusiasm.

The highest-scoring applications also have a sharp sense of next steps. They don’t just say “this study will inform future work.” They say what future work is: a demonstrator, a pilot route, a retrofit program, a port deployment—and the conditions required to get there.

Common mistakes to avoid (and how to fix them)

1) Building a consortium that looks impressive but does nothing

A long partner list won’t save a weak plan. Fix it by giving every partner a specific responsibility and a tangible output. If a partner can’t name their contribution in one sentence, rethink the structure.

2) Promising outcomes that belong in a later-stage demo

Feasibility funding is not the same as a full prototype build or sea trial. If you propose too much, reviewers will worry you don’t understand scope. Fix it by narrowing to the highest-risk questions and delivering the evidence needed for a demonstration project.

3) Ignoring regulation, safety, and class until the end

For maritime, these aren’t “later problems.” They’re core constraints. Fix it by including early engagement and a regulatory pathway outline as part of the feasibility work.

4) Vague emissions claims

Saying “this will reduce emissions” is like saying “this boat will float.” That’s not the bar. Fix it by defining a baseline, stating assumptions, and presenting a simple model with scenarios.

5) A timeline that assumes everything goes perfectly

In collaborations, it won’t. Fix it by building slack into partner review cycles and scheduling early data access and technical workshops.

6) Writing that hides the point

If the reviewer has to reread paragraphs to figure out what you’re doing, you’re in trouble. Fix it by using direct language, repeating the core objective, and keeping each section tied to feasibility outputs.

Frequently asked questions about the UK Clean Maritime feasibility funding

1) Is this funding only for UK organisations?

Yes. The opportunity states UK registered organisations can apply, and the collaboration requirement also specifies other UK registered organisations as partners.

2) Can a university or research organisation lead the project?

Not as the lead, based on the eligibility summary provided. The lead must be a UK registered business of any size. Universities can still be valuable partners inside the consortium.

3) Do I need to apply with partners, or can I apply alone?

You must apply as a collaboration. Solo applications won’t fit this competition’s rules.

4) What kinds of clean maritime technologies are a fit?

The call is framed broadly around innovative clean maritime technologies. In feasibility terms, that could include propulsion and power systems, alternative fuels and infrastructure planning, energy efficiency, operational optimisation, port-side decarbonisation tech, and enabling systems that reduce emissions. The official page will define the boundaries more precisely.

5) How big is the grant per project?

The listing only states the total pot: up to £121 million across three strands. The feasibility strand’s per-project ranges, intervention rates, and eligible costs will be detailed on the Innovation Funding Service page.

6) What does feasibility study mean in practice?

It means you’re paid to answer “Will this work, and how?” rather than “Look, it works.” Expect to produce evidence: models, designs, risk assessments, stakeholder validation, and a plan that can move into demonstration with fewer unknowns.

7) What happens if my feasibility study finds the idea is not viable?

A well-run feasibility study can still be a success if it produces clear learning and prevents expensive mistakes later. Funders generally prefer honest, well-evidenced conclusions over optimistic fog. The key is to design the study so it produces useful results either way.

8) Where do I actually submit the application?

You’ll apply via the Innovation Funding Service, linked from the official UKRI opportunity page (see below).

How to apply (and what to do next, starting today)

First, decide whether you’re truly ready for a collaboration-only feasibility bid. If you don’t yet have partners, make that your immediate focus. Identify one end user (operator/port) and one strong delivery partner (engineering/integrator) and set up a working session to define the feasibility questions you’ll answer.

Second, write a short concept note—one page, no fluff—that states: the problem, your proposed technology, what the feasibility study will prove, who the partners are, and what outputs you’ll deliver by the end. Use that as the document that keeps everyone aligned.

Third, go to the official listing and follow the path into the Innovation Funding Service. That’s where you’ll find the exact scope, rules, and submission steps. Don’t rely on memory or assumptions—Innovate UK competitions are specific, and details matter.
