Biomass gasification is a mature technology pathway that uses a controlled process involving heat, steam, and oxygen to convert biomass to hydrogen and other products, without combustion. Because growing biomass removes carbon dioxide from the atmosphere, the net carbon emissions of this method can be low, especially if coupled with carbon capture, utilization, and storage in the long term.Continue reading “Biomass Gasification an alternative way to produce Hydrogen”
Most hydrogen today is produced from fossil fuels – steam methane reforming of natural gas, partial oxidation of coal or oil residues – and entails large CO2 emissions, from 8.5 tons of CO2 per ton of H2 from natural gas in modern facilities up to 20 tCO2/tH2 from coal. This fossil hydrogen can be called “grey hydrogen”.Continue reading “What is turquoise, or green-blue Hydrogen?”
A presentation by Pete Johnson, Private Equity Fund Leader at Azimuth Capital Management.
Methane pyrolysis for hydrogen, ie “Turqoise Hydrogen,” is a growing field where more and more commercial companies are being launched. The energy required to release hydrogen from methane or natural gas is approximately 7X less than the energy required to release hydrogen from water, but there are technical challenges for operating pyrolysis furnaces at scale, particularly around carbon management, coking, and carbon product control.
Tech start-up C-Zero splits methane into hydrogen and solid carbon, eliminating much of the greenhouse-gas impact.
C-Zero’s technology uses innovative thermocatalysis to split methane – the primary molecule in natural gas – into hydrogen and solid carbon in a process known as methane pyrolysis.Continue reading “Bill Gates-Led Fund Backs Clean Hydrogen start-up”
