Fuel cell integrator secures €3 million investment to scale operational capabilities, a leader in the European hydrogen fuel cell industry, has secured a €3 million investment. This funding comes from the Rotterdam Energy Transition Fund and a reputable private investor deeply embedded in the Rotterdam tech scene. The investment will support zepp in expanding its operational capabilities in response to rising market demands.

This is the first external capital injection for, which has grown into a multi-million company on a bootstrapped basis since its foundation in 2017. This expansion is a strategic move to meet the rising market demand for fuel cell systems as the European hydrogen sector  is moving towards implementation on a larger scale. 

“Receiving this first investment is a major milestone for our team” said Jonas Brendelberger, co-founder of “It’s a strong signal of trust in what we are building here and a perfect fit, bringing on board partners who will further strengthen our roots in the Rotterdam and Delft tech sector.”

Erik van der Zant, Head of Investments at InnovationQuarter and interim fund manager of the Energy Transition Fund: ”Zepp’s ambition is a great match with the mission of the Energy Transition Fund, which is to reduce CO2-impact in the Rotterdam area by supporting promising climate tech companies. InnovationQuarter looks forward to working together with zepp on their growth.”

Alderman Chantal Zeegers of Rotterdam commented on the investment: “The Rotterdam area is responsible for a fifth of all CO2 emissions in the Netherlands. We need to get these emissions down to zero by 2050. Tech-intensive companies like are a big part of the solution and help build a viable hydrogen ecosystem. Rotterdam is happy to participate through our Energy Transition Fund.”

Enabling zero emissions

Zepp’s hydrogen fuel cell systems contain all the hard- and software required to turn hydrogen gas into usable electricity at high efficiency and unparalleled power density. These systems are specifically designed for medium- to heavy-duty applications and enable manufacturers of trucks or machines and shipyards to transition towards zero-emission technology. The large scope of integration minimizes the required integration 

Recent examples of applications with zepp’s technology are the Ab Initio inland barge by Concordia DAMEN, the Rotterdam-based hydrogen water taxi and several Liebherr excavators. Another major success story is the integration of a zepp system into a yard tractor by Terberg Benschop, this vehicle has been operating on hydrogen since October 2020. Upcoming deliveries include two fuel cell powered hydrogen-electric 44t on-road trucks (Europa), as well as a mobile power genset to be used at Amsterdam’s Schiphol Airport.

Last year, secured a €2 million grant from the European Just Transition Fund to support the establishment of their new assembly plant in the greater Rotterdam area, which, once completed, will have an annual capacity of up to 1000 units and will create up to 100 new jobs.

Result of collaboration

The successful fundraising is the result of a long and intensive collaboration between and InnovationQuarter, manager of the Rotterdam Energy Transition Fund. Earlier, InnovationQuarter supported in the development of the world’s first hydrogen-powered water taxi in Rotterdam.

Over JTF

The ‘Energietransitiefonds Rotterdam’ is a €100 million investment fund of the City of Rotterdam. The fund finances innovative companies and large sustainable projects that can contribute to Rotterdam’s energy transition and circular economy. With the fund, the city aims to reduce CO2 emissions, improve air quality and reduce the use of raw materials. InnovationQuarter acts as fund manager for the Rotterdam Energy Transition Fund.
