Marel Power Wins $1.9M for Michigan Power Stack Line

In Plymouth, Michigan, Marel Power Solutions is about to put cooling channels, semiconductor supply, fixtures, and cycle time through the same production line. The company has received a $1.9M Michigan Supplier Conversion Grant to buy manufacturing equipment and move its compact power-stack architecture toward pilot-scale output, beginning with electric-vehicle applications.

The distinction matters because this is public manufacturing capital, not an equity round. Marel is one of 11 suppliers sharing $21M through a program administered by the Michigan Department of Labor and Economic Opportunity, with support from the U.S. Department of Energy's Domestic Automotive Manufacturing Conversion Grant program.

For Marel, the award funds the difficult middle between a working power-electronics architecture and a repeatable product. The company says its configurable power modules and power stacks can reduce the size, weight, semiconductor count, and cost of high-power conversion systems. The pilot line now has to show whether those advantages survive fixtures, suppliers, assembly, testing, cycle times, and customer requirements.

What the $1.9M Award Funds

Michigan's supplier-conversion program is designed to help small and medium automotive manufacturers modernize equipment and adapt to qualified vehicle supply chains. The state announced Marel as an awardee on September 2, 2026, and Marel disclosed its specific $1.9M allocation in a company announcement on September 18. The broader program distributes $21M among 11 suppliers and was made possible by $22.6M in federal support, neither of which should be confused with Marel's individual award.

Marel says the money will purchase equipment for a pilot power-stack production line in Plymouth. That use is narrower, and more informative, than a generic expansion plan. A pilot line is where the company can begin turning compact thermal and electrical designs into a manufacturing process that produces the same result repeatedly.

The award also fits a longer public-support record without creating a clean “total funding” number. A Michigan state report recorded a $100K convertible note in 2023 alongside $1.05M in matching investment, while federal records document earlier power-electronics manufacturing work. Those grants, notes, matching funds, prizes, and appropriations use different capital definitions, so adding them together would create false precision.

The Engineering Claim Enters Manufacturing

Marel builds power modules and power stacks that sit inside converters, inverters, breakers, EV traction systems, chargers, and other high-power equipment. Its core argument is that semiconductor packaging and cooling should be designed as one power-conversion block rather than assembled as a bespoke system for every program.

The official product material describes dual-side cooling, low-inductance packaging, and the ability to use IGBT or silicon-carbide die from multiple suppliers. Marel says different configurations can reduce size and weight, lower semiconductor count, and cut cost. Those are company-reported performance claims, and the public materials use more than one comparison baseline, so the figures should be read as product targets rather than audited results.

There is verified technical depth beneath the positioning. Chief Technology Officer Ian Byers and Chief Operating Officer Gary Miller are named inventors on Marel's granted air-cooled power-converter patent. A Department of Energy project report also documents Marel's manufacturing work for heavy-duty fuel-cell vehicle applications. CEO Amrit Vivekanand is now responsible for carrying that technical base into a repeatable production and commercial system.

One Architecture, Three Power Problems

Electric vehicles are the first application named for the new production equipment. A smaller, lighter traction inverter or onboard charger can return space and weight to the rest of the vehicle, while a configurable platform could reduce the engineering work required for each program. That is the immediate manufacturing case behind the grant.

Marel also targets defense systems and data centers. Defense platforms must move more power through vehicles, aircraft, naval systems, and field equipment where size, weight, cooling, and reliability are inseparable. Data centers face a different version of the same physical constraint as AI compute drives higher rack power and increases the value of every unit of floor and rack space.

The shared architecture is commercially attractive because system builders may be able to select a configuration instead of paying for a new converter design from the ground up. Marel also advertises IP licensing, which gives the company another path to market if customers want the architecture without buying every finished subsystem directly. No named defense or data-center customer deployment was independently verified, so those markets remain supported application targets rather than proven commercial scale.

The Proof Moves to Plymouth

Public hardtech capital often pays for the stage that is least glamorous and most decisive. A prototype can show that an idea works once, while a pilot line begins to show whether it works repeatedly with real tooling, suppliers, quality controls, labor, and customer deadlines. Marel's grant is valuable because it assigns money to that production test rather than treating another demonstration as the finish line.

The open questions are operational. Marel has not publicly detailed the line's capacity, equipment list, hiring commitments, customer programs, or target production economics. The company must also show how its performance and cost claims hold under customer conditions and whether a platform that begins with EV applications can travel efficiently into defense and data-center programs.

The state has funded the machinery needed to make those questions answerable in Michigan. Each repeatable power stack that leaves the Plymouth line will turn a density claim into manufacturing evidence, and that evidence will decide how far Marel's architecture travels beyond the first vehicle program.
