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 the feedstock is biogenic then the lifecycle emissions are comparable with green hydrogen production using solar and wind and electrolysis.
The MIHG technology can be configured to produce hydrogen in several ways.
One option is to connect a hydrogen electrolyser to use some or all of the electricity produced from the MIHG system. This configuration has the advantage of enabling hydrogen production to be scaled to demand and to enable the plant to sell electricity whenever prices are very high, such as at peak times of the day.
The second option is to directly convert the clean syngas to hydrogen using a water gas shift unit and separate the hydrogen from offgases in a pressure swing adsorption unit. These technologies are off the shelf units, used in conventional hydrogen plants throughout the world. The main advantage of this configuration is that it maximises hydrogen production and therefore is forecast to achieve low levelized costs of hydrogen production.
