H2-Gensets, H2-CHP systems and BESS

As a hydrogen-experienced team of engineers, technicians, and strategy experts, we develop H₂ systems that combine advanced technologies economically and make them usable in decentralized applications.

Hybrid Systems for Power and Heat from Hydrogen

• Zero emissions & silent operation. No CO₂, no NOₓ, no particulates.

• Hybrid-ready. Can be combined with renewables and battery storage.

• Grid-independent. Suitable for island operation and off-grid use.

• Reliable. Backup for critical infrastructure.

• Flexibly scalable. Adaptable to different power ranges.

• Eligible for subsidies. Government funding and ESG-compliant.

The Global Energy Gap Is Real.

We are closing it.

• On-site hydrogen generation ensures energy autonomy and sovereignty anywhere

• Integrated platforms combine renewables, electrolysis, battery storage (BESS), and hydrogen fuel cells to deliver electricity, heat, and critical backup functions.

• Modular systems enable black start, island operation, peak shaving, and grid stabilization.

• Scalable solutions from 50 kW up to multi-MW – stationary or mobile, off-grid or grid-connected.

• Zero emissions: no CO₂, no NOₓ, no particulates – with ultra-low noise levels.

• OEM/CKD model for local manufacturing and full regulatory compliance.
