Of the mix of fossil fuels we use, natural gas has been growing rapidly, significantly displacing coal. However, the current use-model for natural gas is simply to burn it for heat, creating large CO2 emissions. We have been exploring a different scientific and economic concept for the use of natural gas. The proposition is that natural gas – primarily methane – can be chemically decomposed into solid carbon and hydrogen with no carbon dioxide produced at all. The hydrogen can be burned as fuel instead of natural gas, producing only water and heat, and the carbon sold for other uses. Solid carbon is quite valuable, and with the right processing can be turned into lightweight structural composites. This approach is much more profitable than just burning natural gas, all without CO2 emissions. Here, we will discuss here some novel strategies we are using to make this vision a reality.
