Current power supplies for military and government operations rely heavily on diesel generators, which are often oversized and lead to inefficiencies and increased emissions of heat, noise and exhaust fumes. Diesel dependency is a critical vulnerability and severely limits the resilience and operational capability of deployed forces, especially in conflict zones where fuel supply requires regular convoys through contested areas. This logistical challenge must be addressed from the perspectives of improving operational capabilities, increasing resilience and autonomy, reducing the environmental footprint and costs, reducing the signature and visibility of deployed forces and expanding their area of operations.

In addition, NATO forces have set themselves the goal of becoming climate neutral by 2050. In June 2021, the Defence Ministers of NATO member states issued a Joint Statement on the Climate and Security Agenda, committing to recognise climate change as a threat to international security and to take action to minimise the impact of defence activities on the environment.

New technologies must therefore be combined to sustainably reduce the need for diesel and expand the capabilities of troops. Only in this way can energy be permanently provided in a demand-oriented, secure, cost-effective and regenerative manner. Thus, the energy infrastructure of armed forces no longer depends on individual methods of energy generation, but focuses on selecting the appropriate energy sources for the requirements of each mission.

Mobiles Energiesystem Mobile Stromversorgung Camp Supply

For an environmentally friendly energy supply, a demand-oriented, safe and regenerative substitute energy source is needed. In the future, EU forces are expected to need only less than 50% of the volume of diesel needed to meet their energy needs today. At the same time, electrification will continue to advance . In 2019, the USMC found a 700% increase in electrical energy consumption over the last five years and projected the same increase within the next three years. Another study found that electricity demand per soldier has increased by a factor of 20 since World War II and will continue to increase in the future (Powering the U.S. Army of the future, 2020).

First of all, existing diesel generators should therefore be used more efficiently and in a more hybrid way. In addition, a central, intelligent energy storage system will have to combine all energy sources in the future and decide independently and intelligently which energy mix is ideal for the prevailing climatic and tactical conditions. This is the only way to achieve a secure, resilient and independent power supply that also reduces the carbon footprint.

AXSOL’s Hybrid Battery Systems thus represent a central, intelligent energy storage system. They combine the intelligent system control of the stationary Energy Container Solutions with mobile power supply through the ultra-mobile ARVEY B2 battery storage systems. A fully integrated energy storage system for a flexible, uninterrupted, self-sufficient and secure power supply in demanding environments.

The conversion and hybridisation of the military’s energy supply will take place in three stages:

1. hybridisation of diesel generators with renewable energy sources and battery systems will help reduce fuel consumption and emissions by up to 30%.

2. the introduction of dual-fuel fuel cells (diesel to hydrogen) will facilitate the transition to sustainable fuels and increase overall energy efficiency by 100% (60% fuel consumption and emissions savings).

3. renewable energy will act as the primary energy source with hydrogen fuel cells and diesel back-up.

As the central charging station of the Hybrid Battery Systems, the Energy Container Solutions bundle the data of the generators and consumers in order to decide situationally on the energy flow and power distribution in the system. The goal is a 100% secure power supply in operation, minimization of supply costs and priority use of renewable energy generators. The ultra-mobile ARVEY B2 battery storage units, as the mobile part of the Hybrid Battery Systems, are charged in the Energy Container Solutions slide-in racks and can be removed and transported to the site of operation when needed.

The ARVEY B2 mobile battery can also be coupled with a fuel cell from SFC. This coupling has several advantages. By using these systems, the risk of loss of life and material during fuel resupply in conflict areas like Afghanistan and Mali can be reduced. This is because transporting fuel requires regular convoys through combat-affected areas. In addition, the coupling increases the efficiency of the entire system compared to diesel generators. By communicating between the two systems, only the necessary power is provided, which leads to a significant increase in overall efficiency. In addition, operation is safer because methanol is used as fuel instead of diesel, which reduces the risk of accidents. Finally, costs can be significantly reduced as the price of diesel in operating environments can be as high as €180 per litre. The use of fuel cells and batteries can significantly reduce the cost of fuel.


Pure hybridization of diesel generators can save up to 30% diesel. The additional integration of renewable energy generators further reduces consumption and operating costs. The higher overall energy efficiency reduces the costs for operating resources, maintenance and logistics.

By storing and analyzing generator and consumer data, insights into the actual power consumption of individual applications are made possible. As part of an energy situation picture, the data from mobile and stationary applications are important prerequisites for tactical decision-making and planning.

Hybridization conserves the diesel generator, reducing maintenance and downtime. Lower fuel consumption increases the strategic autonomy and self-sufficiency of camps, reducing the logistical effort and risks of supply convoys.

The combination of innovative system solutions for the mobile and stationary use of electricity not only enables the supply of mobile operations, but also of FOBs, camps and larger bases. The ultra-mobile ARVEY B2 battery storage units are loaded in the Energy Container Solutions slide-in racks and can be flexibly removed and transported to the mission when needed. Weighing 49 kg, they can be transported by two men in the field and deliver up to 2,400 W of power.
