PowerCell Sweden Joins EU’s MiNaMi Project for Maritime Decarbonization

Big news for maritime decarbonization: PowerCell Sweden AB is hopping on board the EU-funded MiNaMi project, aiming to roll out Europe’s first megawatt-scale Proton Exchange Membrane (PEM) fuel cell system specifically designed for commercial shipping. Coordinated by VTT in Espoo, Finland, this effort brings nine organizations from seven countries together to prove that zero-emission shipping can be both rock-solid and cost-effective, all while boosting hydrogen fuel cells in the mix.

• Partners: PowerCell Sweden AB, VTT, DFDS A/S, ABB Marine & Ports, Vaisala, Allengra, SINTEF, Centre for Research and Technology Hellas, Fondazione Bruno Kessler.
• Objective: Build a megawatt-scale PEM fuel cell system that runs smoothly for over 80,000 hours.
• Location: Espoo, Finland (hub), with a pan-European network spanning Northern and Central Europe.
• Budget: A total of €7 million in EU funding, with PowerCell’s slice at roughly €2.6 million through 2028.
• Key Targets: Cover more than one million nautical miles reliably at a cruising speed of 12.5 knots.

Technical Deep Dive

The beating heart of MiNaMi is the PEM fuel cell. These nifty devices turn hydrogen into electricity, spitting out only water as a by-product. They run at a cool 60–80°C, kick off in no time, and pack a punch in power density—perfect for those tight maneuvers when you need extra oomph. To juice up to megawatt-scale, the design links several 225 kW modules side by side. Each module feeds into a shared DC bus through DC/DC converters, so if you need more power, you just snap in another module. Clean, simple, scalable.

Durability has been a thorny issue. After all, industrial marine engines can chug along for decades, so our fuel cell technology needs to be just as tenacious. The MiNaMi squad has set a bold goal: keep each stack running smoothly for over 80,000 hours. That’s enough juice to rack up more than one million nautical miles at 12.5 knots—roughly twenty laps around the globe for a standard cargo ship.

Getting hydrogen flow just right matters too. Allengra steps in with advanced sensors and smart control algorithms that constantly measure and tweak the hydrogen mass flow in real time. This keeps the stacks humming at top efficiency and shields them from damage when power demands swing up or down—crucial for long-haul runs where every kilowatt counts.

Consortium and Funding Structure

The project sits under the EU’s Clean Hydrogen Partnership umbrella, a clear sign of Europe’s push towards climate neutrality. VTT grabs the coordination reins from its Espoo labs, tapping into Finland’s reputation as a go-to spot for clean-tech research. On the industry front, every partner chips in something unique:

• DFDS A/S: Provides hands-on maritime know-how, from real-world vessel specs to operating scenarios for testing.
• ABB Marine & Ports: Handles electrification and automation—think power converters, control systems, and grid hookups.
• Vaisala: Delivers environmental and industrial monitoring to keep tabs on system performance across different weather and sea states.
• SINTEF, Centre for Research and Technology Hellas, Fondazione Bruno Kessler: Tackle materials research, system modeling, and test validation.

As for PowerCell, its €2.6 million contribution goes towards tweaking its Marine System 225 modules for megawatt-scale operation and running sea trials. These 225 kW units already boast Lloyd’s Register Type Approval, proving they tick all the right maritime safety and performance boxes.

Strategic and Market Implications

Let’s face it: shipping is a tough nut to crack when it comes to emissions. Responsible for almost 3% of global greenhouse gases, the sector’s feeling the heat from regulators like the IMO and the EU, who’ve set aggressive carbon intensity targets for 2030 and beyond. By nailing down both scale and longevity, MiNaMi tackles two of the biggest roadblocks for putting hydrogen fuel cells on deck. If everything goes as planned, we could see this fuel cell technology jump from pilot projects to early commercial use within just a few years—a real game-changer for shipowners such as DFDS, keen to slash emissions without giving up performance or range.

For PowerCell Sweden, the marine world represents a premium-efficiency playground. Rather than chasing mass-market volume, the company is zeroed in on applications where uptime and reliability are non-negotiable. A win in MiNaMi could cement their standing and unlock doors in rail traction, stationary power, and heavy machinery—though those markets are more of a future horizon than an immediate target.

Infrastructure and Environmental Impact

Of course, none of this works without the right hydrogen infrastructure. Scaling up marine fuel cells means stepping up hydrogen production, bunkering, and port facilities in tandem. Across Northern Europe, several ports are already piloting zero-emission corridors, backed by national clean-hydrogen blueprints. Having a solid, standardized fuel cell module in hand makes it easier for port authorities and fuel suppliers to justify investments in storage and distribution.

On the environmental side, PEM fuel cells emit nothing but water vapor—no CO2, no SOx, no particulates. If megawatt-scale systems catch on, shipping’s 3% slice of global CO2 could shrink dramatically, turbo-charging both the EU Green Deal and the IMO’s 2050 net-zero ambition. That’s what sustainable energy is all about.

What to Watch Next

Over the next 24 months, keep your radar locked on the MiNaMi milestones: slapping multiple 225 kW modules into a single prototype, fine-tuning the control systems, and heading out for sea trials on a commercial vessel. The key metrics to watch? Overall efficiency, hydrogen consumption per nautical mile, stack degradation rates, and safety performance under real-world conditions.

Meanwhile, PowerCell’s investor updates should spill the beans on R&D spend, test milestones, and any early commercial sale chatter. On the policy side, new EU or IMO rules around maritime hydrogen could either grease the skids or throw a wrench in the works—so stay tuned.

About PowerCell Sweden AB

PowerCell Sweden AB is a Stockholm-listed specialist in fuel cell technology, focusing on maritime, aviation, and stationary power. Their game plan zeroes in on premium-efficiency segments, and they’ve teamed up with Robert Bosch GmbH for global distribution muscle. The Marine System 225, already vetted by Lloyd’s Register, is their first step toward full megawatt-scale solutions.

Joining MiNaMi is their big play to bring zero-emission shipping into the mainstream. We’ll be keeping a close eye on how this project unfolds—because it might just rewrite the playbook for clean maritime propulsion across Europe.
