Hydrogen Result
Assumptions:
-
Green hydrogen will be purchased by a third party and sourced to the site on hydrogen vehicles with negligible footprint [12].
-
Hydrogen storage will be sized for 2 days [13] of continuous operation and installed on site.
-
The hydrogen boiler efficiency is considered to be 97% [13].
-
Currently, hydrogen cost is taken as £4/kg which is predicted to decrease to £2/kg by 2050 [14].
Results
​Process heating carbon emissions can be reduced by 93%.
​Boiler operational steam rating requirement would be 1.4 tph. Total capital cost of £0.57 million will be required with 72% coming from hydrogen storage cost. As the green hydrogen is predicted to become same price as natural gas around 2030, savings will be seen around the year 2030. Hence, the payback can be expected in 17 years.
