Schiphol tests world’s first hydrogen ground power unit

Schiphol Airport is the first worldwide to test a hydrogen-powered Ground Power Unit (GPU). The H2-GPU can power KLM Cityhopper aircraft on-site, for example, for lighting and power in the cockpit. These new GPUs are more environmentally friendly than battery-based and diesel GPUs.

The test is part of the TULIPS partnership initiated by Schiphol and subsidized in part by the European Commission. The project is a partnership of 33 European aviation parties and knowledge institutes in which new technologies and procedures are being developed to accelerate the sustainability of airport operations.

Cleaner and emission-free

The aviation sector is not only working on greening the air but also working with ground handlers to achieve emission-free operations. For example, some aircraft at the gate are already powered by electric GPUs. The e-GPUs must be moved to charging points. The new H2-GPU, however, can be refueled on-site, saving time and vehicle movement.

Moreover, e-GPUs sometimes have insufficient capacity, so diesel GPUs are still needed. The hydrogen GPU is also a cleaner, emission-free solution in that area.

With the support of Zepp.solutions

Zepp developed the H2-GPU. solutions, a Delft-based scale-up, and Austrian GPU manufacturer Dynell. Zepp.solutions is also working on Europa, a next-generation hydrogen-powered truck.

Europa offers the same payload and workflow as a diesel equivalent with a more than 700 km range and the ability to tow an ISO trailer (13.6 m/45 ft container). Only a Europa with a 350-bar X150 fuel cell system is available for now. Later, Europa trucks are due with a 700-bar hydrogen storage system. The latter option provides a range of more than 1,000 km on a single refueling.

Zepp. solutions are also collaborating on Happs, the world’s first-ever larger passenger aircraft (40-80 seats) powered by liquid green hydrogen.
