Uninterruptible power supply for any mission

Shifting parameters for military exercises and operations as well as ambitious environmental protection goals pose considerable challenges for the future energy supply of military vehicles.

Ongoing vehicle upgrades to increase operational readiness and operational capability lead to increasing energy requirements. Conventional technology alone, however, can no longer cover these requirements bearing in mind the restrictions caused by form-fit-function concepts. The scope for improving the efficiency of current internal combustion engines is also very limited, while at the same time the consumption of fossil fuels needs to be reduced.

Energy supply systems that are sustainable in the long term must therefore fulfil exacting requirements: They must meet military capability requirements and be free of fossil fuels by 2045 in order to ensure operational readiness and contribute to achieving climate protection goals.

the solution
Variable speed generators as a hybrid system

The variable speed generator as a hybrid system developed by ESG and 2H Energy is the first proven power supply solution to reduce dependency on fossil fuels. It offers a transitory technology to meet the goals for future power supply systems and already demonstrates multiple benefits for military deployment today.

    of between 45 Hz to 65 Hz.
  • Direct current  continuously available for up to 1 hour
    without the diesel engine running
  • Diesel engine always runs at the optimum speed

The variable speed generator as a hybrid system developed by ESG and 2H Energy will in future be deployed as the new Prime Power Unit for the world's most powerful artillery location radar COBRA (Counter Battery Radar).

For many years, ESG has been responsible for the in-service support and further development of the COBRA system as prime contractor and System Design Authority (futher  information here).
