According to Dongwu Securities' forecast, if calculated based on the current electricity consumption of 5 kWh/cubic meter and electricity price of 0.3 yuan/kWh, the total cost of alkaline water electrolysis hydrogen production is 25 yuan/kg, while the cost of coal-based hydrogen production is 9.6...
The conversions rates used were: for solar resource, 3% of land was allocated for the analysis after removing the exclusions with a conversion rate of 52.5 kWh/kg of hydrogen;for biomass hydrogen, the conversion rate of 13.4 kg BS/kg H2 was assumed. Wind resources at 50 m above ground ...
[46] The report by IRENA.ORG is an extensive factual report of present-day industrial hydrogen production consuming about 53 to 70 kWh per kg could go down to about 45 kWh/kg H2.[47] The thermodynamic energy required for hydrogen by electrolysis translates to 33 kWh/kg, which is higher ...

Running at high temperatures and high availability, the pilot results reveal the Bloom Electrolyzer is producing hydrogen at 37.5 kWh per kilogram of hydrogen at the system level. Alternative efficient electrolyzer technologies, such as PEM or Alkaline, consume as much as 52 – 54 kWh per kilogram...
(300 Bars) Consumption : 48 kWh / kg H2 Degradation : 0,1% / 1000 h (of stack lifetime) Utilization factor : 70% Power price (assuming IG: 150GWh+ p.a. power band) Price : 50,4 € / MWh (incl. network access charges and taxe...
kWh/Nm3 (45kWh per kg of H2) operating at about atmospheric pressure and 60°C−80°C (Gallandat, 2017). Relating these specific energy requirements to the upper heat of reaction of 3.55kWh/Nm3, see Eq. (2.8), yields an efficiency of up to 87%....
The integrated plant has been designed to produce hydrogen at 0.0184 kg per second, while freshwater is produced at 82.71 kg per second. The plant can also generate 5027 kW of power at the defined conditions. Energy and exergy efficiencies of the designed system have been computed as 42.57% ...
50 kWh/kg-H2 is already close to ideal electrical efficiency, so the only way to cut the per-unit capex cost is to amortize equipment over a longer time period. But even if 0% financing and $0 maintenance costs can be found, hitting $1/kg-H2 will require (eg) 24/7 electricity for...
On the other hand, regarding the operation phase, in other publications [22, 55, 69, 70] there is a tendency towards lower electricity demand values for AEC (48–52 kWh/kgH2) than for PEMEC systems. Thus, the overall LCOH results based on the assumptions of this study are within a ...
