Fossil fuel-free hybrid generator

The quality of cross-ING is based on the engineering competencies. Through the competence centers, the people at cross-ING provide an entrepreneurial outlet for their passion and a platform to implement projects. That is cross-ING.

We are developing a new, hybrid APU (auxiliary power unit) that can be operated autonomously by means of alternative, regenerative fuels. The integrated buffer battery ensures that no energy needs be produced during low power requirement phases.

In this way, we guarantee efficient operations and autonomous operation.

RUAG looking into


The proposed solution is modular and can be tailored to individual needs.

Tactical advantages

The fact that there is no conventional diesel-based electricity generator ensures enhanced thermal, acoustic and olfactory camouflage.


The hybrid architecture makes it possible to cover short-term increased electricity requirements.

  • Why the idea?
  • What is our value proposition?

The DDPS and other blue-light organizations are subject to political and social pressure to reduce CO2 emissions in the medium-to-long term. Efficient use of energy sources (fossil or sustainable) is therefore a prerequisite. The operational capability is nevertheless ensured at all times

A hybrid APU (auxiliary power unit) ensures that the combustion engine/fuel cells only runs when a high output is required. When low output is called for (e.g. at night), the electricity can be supplied via the buffer battery. Furthermore, the energy is produced by means of alternative energy sources (e.g. hydrogen or methanol).
