> The second, which is still under development but about to make its debut, is what they’re calling the Modern Electron Reserve, which rather than burning natural gas — which is mostly CH4, or methane — reduces it to solid carbon (in the form of graphite) and hydrogen gas. The gas is passed on to the furnace to be burned, and converted to both heat and energy, while the graphite is collected for disposal or reuse.
And there's a picture of what's left after they extract just the Hydrogen from PNG/LNG for one day of home heat.
Letting the grass grow longer is one way to absorb carbon locally; longer grass is more efficient at absorbing carbon (e.g. carbon emitted by comparatively inefficiently burning natural gas for heat (an exothermic critical reaction))
