In a world that consumes resources faster than our nature can reproduce them we need to adopt more and more re-use practices—particularly urgent for contemporary Carbon. Using Fossils is an import of pre-historic Carbon into present age and we keep doing it because end of lifecycle carbonaceous resources are either used for energy recovery only, or dumped to rot. In any case, Carbon is disposed into Atmospheric Carbon Stock. Carbohydrates contain carbon [C], hydrogen [H], and oxygen [O], mostly in a ratio of C_nH_2nO_n and store bio-energy and genetic information controlling the flow of chemical energy through metabolism. Hydrocarbons on the other hand are chemical compounds that consist only of the elements carbon and hydrogen. Both are formed by a carbon skeleton having hydrogen atoms attached to that backbone. At 2H₂:1C ratio 55% stored che- mical energy stems from Hydrogen and 45% from the Carbon. If burned for energy recovery, the Hydrogen content forms water vapor, but its Carbon carrier discards CO₂ into atmosphere as if it was a one-way pack. Why not Capture Carbon physically for new Hydrocarbon Synthesis’ Use prior to direct electrochemical Energy Recovery from Hydrogen rather than today’s three step Power generation (—heat—mechanical power motion energy—electricity—). For example for bottom-up Ethylene Synthesis physically Captured Carbon replaces 2 ltr crude oil per kg ethylene output. At a similar Energy Yield, only reduced by the CO₂ transformation losses of the Carbon Capture process, the Captured Carbon can be additionally used as a resource at arms’ length market prices, adding to Cost-effectiveness and making the Energy more economic at an increased Environmental Performance due to increased Carbon Efficiency.
