Munich / Nuremberg, 20.2.2026
Siqens GmbH, a leading supplier of methanol fuel cells and innovative hydrogen technology, will be presenting its Ecoport 800/1500 fuel cell systems for the first time at Enforce Tac 2026 in Nuremberg from 23 to 25 February (booth 6-157). As off-grid power generators, the Ecoport systems offer a reliable, low-noise and low-maintenance power supply – specifically designed for the special requirements of security and defence forces
Ecoport fuel cells provide a continuous supply of electrical energy – without the typical disadvantages of conventional generators. While diesel generators are notorious for their noise, exhaust fumes and high maintenance costs, Siqens systems operate almost silently and emission-free.
The Ecoport 800 provides up to 800 watts of peak power (500 watts in continuous operation), while the Ecoport 1500 delivers up to 1,500 watts of peak power (1,000 watts in continuous operation).
‘In the security and defence sector, there are special requirements for power supply,” emphasises Siqens Managing Director Dr Thomas Klaue. “Reliability, discretion and operational readiness under extreme conditions are crucial. Our Ecoport systems meet precisely these requirements: they operate almost silently, function in all climate zones from -20°C to +50°C and are virtually maintenance-free. This makes them ideal for mobile command stations, border protection and autonomous surveillance towers.’
The advantages of Ecoport technology for security and defence applications
Quiet operation: With less than 45 dB during operation, the SIQENS Ecoport enables discreet operations where acoustic camouflage is crucial
Maximum reliability: The patented high-temperature PEM technology (HT-PEM) works regardless of weather conditions and delivers consistent power – without the cold-start problems typical of diesel generators.
Minimal maintenance: Unlike combustion engines, fuel cells do not require regular oil changes or costly maintenance intervals. This reduces operating costs and increases availability in use.
Efficient energy supply: Methanol as a hydrogen carrier offers a high energy density of 4.4 kWh per litre and is available worldwide. Storage is straightforward and significantly safer than with petrol or diesel.
Emission-free: Ecoport systems emit neither particulate matter nor nitrogen oxides and reduce CO₂ emissions by 99 per cent compared to diesel generators.
Typical application scenarios in the security and defense sector include:
Mobile command posts: Reliable power supply for communications and IT systems in field use, without attracting attention due to generator noise or hot exhaust gases
Border protection: Long-term, autonomous energy supply for surveillance technology in remote areas without grid connection.
Autonomous surveillance towers: Continuous power supply for cameras, sensors and communication systems – regardless of weather conditions and without regular maintenance visits.
The fuel cell systems are designed as fully automatic battery chargers and can be seamlessly integrated into existing off-grid or backup energy systems. The systems can be monitored remotely, and updates and servicing are carried out over the air. This increases operational readiness and significantly reduces logistical costs.
At Enforce Tac, Germany’s leading trade fair for security and defence, Siqens will demonstrate the practical advantages of Ecoport technology and will be available for discussions on specific application scenarios.
