Hydrogen
Hydrogen is a clean energy carrier which has been identified as an important solution to reduce our GHG emissions. At point of use hydrogen emits no GHG emissions and can be used in a wide range of applications, including:
-
fuel cell vehicles for mobility
-
energy storage to balance intermittent renewables
-
producing renewable chemicals, such ammonia and methanol
-
industries such as steel making
-
co-injection in the pipeline network to decarbonise natural gas
Today over 98% of hydrogen production globally is from fossil fuels which has significant GHG impacts. The production of hydrogen without emissions is gaining attention globally.
The MIHG technology can be used to make low-cost hydrogen with low-emissions. The graph below provides estimates of levelized cost of hydrogen production from a range of technologies. Wildfire Energy's MIHG technology is forecast to have one of the lowest levelized costs of hydrogen production.
The lifecycle GHG emissions of producing hydrogen using the MIHG technology depend on the feedstock being processed. If using putrescible waste the net emissions are negative due to avoided landfill gas emissions. If using biomass the net emissions are comparable with green hydrogen production using solar and wind and electrolysis.
MIHG Waste to Hydrogen Process
The MIHG technology can be integrated with proven gas processing technologies to produce purified hydrogen from waste. The process involves using a water gas shift (WGS) unit and a pressure swing adsorption (PSA) unit. Tail-gas from the PSA is used to generate power and heat to run the plant. These technologies are off the shelf units, used in conventional coal and natural gas fed hydrogen plants throughout the world.
