“Working 24/7 at our mobile batching plant for the Melbourne Airport upgrades, we needed off-grid power that could cut emissions without compromising reliability. The GEH2 has delivered: it manages the sharp peaks of concrete production and low-load periods seamlessly, while enabling us to significantly reduce site emissions, diesel reliance and noise. In a tight footprint, hydrogen manpacks have provided a practical, low-impact fuel supply — helping us advance our sustainability goals and improve on-site air quality without the time and cost of a temporary grid connection.”
