Author's Note: How Carbon-neutral E-fuels Work

It's easy to mistake NGVs as a new concept, but they've been around a long time. My father, who worked in the West Texas oil fields in the late 1940s and early '50s, used to tell stories of guys running their beat-up trucks on natural gas. Wonder what those roughnecks would think today of synthetic methane or the new Audi A3 Sportback TCNG?
