Frequently Asked Questions

Q: What is the difference between HYDRA-G (high‑pressure) and HYDRA‑M (solid‑state) series?

A: HYDRA-G uses compressed gaseous hydrogen (CGH₂), typically at 70MPa, to support higher-power applications and rapid refueling. HYDRA-M uses solid-state metal hydride hydrogen storage at near-ambient pressure, making it better suited to portable, tactical and applications where high-pressure hydrogen storage is impractical.

Q: Do I need special infrastructure for the 70MPa systems?

A: HYDRA-G mobile systems are designed to work with standard 70MPa hydrogen refueling infrastructure where available. For stationary deployments, SOLIDHYDRO can support hydrogen supply solutions such as tube trailers and on-site compression systems, depending on site requirements.

Q: How do I choose the right HYDRA-G power level?

A: Choose the 3.3kW system for UAVs and light mobility, the 120kW system for heavy-duty vehicles and industrial power, and the 205kW system for stationary, mining and marine applications. Final sizing depends on continuous power demand, peak load, duty cycle and hydrogen supply conditions.

Q: What certifications do HYDRA‑G systems hold?

A: HYDRA-G certification varies by model and application. The 120kW and 205kW systems have completed CAERI type approval. Contact SOLIDHYDRO for applicable certification and test documentation for your target application.
