The capital cost of conventional electrolysers is very high and it contributes up to 70-80% of the overall cost of hydrogen. Therefore even if the electricity is free, the cost of hydrogen would still be over £2/kg H2 due to the capital cost for 1MW scale electrolyser running continuously for 10 years. But in reality renewable energy powered electrolysers would only run for about 30% of the time of the year at part load rather than at its full capacity, thus only about 15% capacity utilisation factor, resulting in higher cost of green-hydrogen of around £6-8/kg H2. But when the electricity cost (£1-3/kg H2 depending of tariff) and servicing costs (£0.5-1/kg H2) are added the overall cost of hydrogen tends to be about £7.5-£12/kg H2, which is much higher than equivalent diesel or LPG price.
Engas Global is offering a combined electrolyser + hydrogen compression technology at 90% lower cost than conventional electrolysers to address this key challenges to make hydrogen viable to displace petrol/diesel, or fossil natural gas/ LPG.
Far fewer companies make hydrogen compressors than electrolysers today. The lack of cost effective hydrogen compressors in small/medium scale influenced the electrolyser-stacks to be pressurised (10-30bars), which in turn increases the parts-counts of electrolysers adding a significant complexity in the balance of plant. However we still need up to 350-700bar storage pressure, thus an external compressor is still needed beyond the pressurised electrolyser stacks. There the combination of 10-30bar pressurised stacks along side a 350-700bar compressor makes any small/medium scale hydrogen project very expensive (potentially unviable) due to the individualised high capital costs of both pressurised electrolysers and a separate multi-stage compressor up to 350-700bar. Engas Global solved this problem by our atmospheric electrolyser stacks integrated with our own unique hydrogen compressor at a fraction of the cost of the conventional electrolysers

Engas is also bringing in 1-3kW low pressure electrolysers for onsite hydrogen production integrated with a low pressure hydrogen storage tanks to potentially use for domestic-cooking eliminating the need for expensive LPG cylinders, or natural gas or firewood in many developing or developed countries. Clean cooking using hydrogen: This solar-hydrogen cooking has the potential to address the very significant clean cooking challenges that over 2 billion people faces in the Africa, Asia and South America.
This Innovate UK funded unique hydrogen compressor capable of scrubbing KOH from hydrogen and then drying hydrogen alongside compressing in a single step whilst operating at close to 98% volumetric efficiency unlike any piston/diaphragm, centrifugal, screw, rotary type compressors. This will be a single phase low power, high pressure hydrogen compressor enabling home hydrogen refuelling combined with our smaller modular electrolysers producing up to 1kg hydrogen/day which is equivalent to drive up to 100-150 miles/kg hydrogen using a suitable fuel cell car.
The following presentations and hydrogen safety video production is intended for basic awareness on hydrogen energy systems, costing and safety. Please contact us for more detail information if you have any queries.
The minimum Ignition Energy of hydrogen should be considered with respect to its concentration (air-H2 mixture), however often people refer to 0.02mJ with respect to about 29% hydrogen concentration in air, which might be difficult to sustain in a ventilated place due to the 4-6 times diffusion coefficient of hydrogen gas than natural gas or LPG. The required minimum ignition energy of hydrogen at 4% hydrogen in air (i.e. the LEL= 4% hydrogen in air) is about 5mJ according to various models (experimental and predictive), which is comparable with methane and other flammable gases. Therefore having hydrogen leak detectors set at 25% of LEL i.e. 1% hydrogen in air mixture, should provide an early warning system to mitigate the risk before it can reach anywhere near 29% concentration in air. Having said that the quantum of energy (HHV) in hydrogen in ambient pressure (i.e. at 29% H2 in air mixture) would still be 1/3rd of Methane (HHV) because the hydrogen has the lowest volumetric energy density (kWh/Nm3) than any other gaseous fuels.
