Additionally, the carbon 2.2 A comparison of greenhouse footprint of the pyrolysis process can be as low as 1.8 gas emissions kg CO2eq/kg H2 depending on the type of pyrolysis pathway and source of reaction energy (i.e., if the The key motivations for using natural gas pyrolysis by-product solid carbon is sequestered or finds use in are lower greenhouse gas emissions compared to the non-combustion. [...] For thermal pyrolysis, the cost of the 5 4.5 natural gas feed and fuel is the main component of 4 the LCOH, whereas, for plasma pyrolysis, the CAPEX 3.0 is the major contributor. [...] In the base case, we considered a also increase corresponding to the price of natural cost of 8 USD/MMBtu for natural gas and applied a value gas; thus, the comparison between grey and turquoise of either 0 or 0.4 USD/kg to the carbon by-product. [...] Global gas prices tend to rise and fall depending on the demand– LCOH (USD/kg) 14 Natural Gas Pyrolysis: A Bridge to a Green Hydrogen Economy Effect of carbon by-product prices Figure 10 High gas prices affect both SMR and thermal pyrolysis comparably The selling price of the carbon by-product from pyrolysis depends on various factors such as the quality and 5 4.5 morphology of the carbon, existin. [...] The addition of natural gas transmission the possible injection points where a pyrolysis plant tariffs and taxes will drive up the price of the delivered could be located for introducing hydrogen into the gas natural gas.
