FOLLOW THE CARBON — For Engineers, Policymakers and Investors

FOLLOW THE CARBON — For Engineers, Policymakers and Investors When a new energy technology is presented, the first question should not be: Is it green? Is it renewable? Is it net zero? Start with thermodynamics. Define the system. Define the surroundings. Draw the boundary. Then identify what crosses that boundary. Follow the mass. Follow the energy. And specifically, follow the geological carbon. Every energy system can be examined this way. Step 1 — Start with the basic process Mass + Energy Input → Process → Mass + Energy Output Nothing controversial here. It is simply a defined system and its flows. Step 2 — Ask what happens to the output If an output can be recovered, converted and returned as an input: Input → Process → Output → Recovery → Conversion → Recycled Input ↻ A linear material flow has become a circulation loop. Step 3 — Follow carbon and energy separately This distinction is essential. Carbon can circulate as an inventory. Energy must continue to flow through the system. Energy is required for conversion, capture, compression, hydrogen production, pumps and other processes. There are unavoidable thermodynamic losses. There is no claim of perpetual energy. Step 4 — Now examine Carbon Recycling Technology (CRT) Follow the carbon: Carbon-containing fuel → Energy conversion → CO₂ → Capture → Conversion → Recycled carbon-containing fuel → Energy conversion ↻ Do not stop following the carbon when it becomes CO₂. Continue following it. Then ask: How much fresh geological carbon must continuously cross the external system boundary once the circulating carbon inventory has been established? That is the important question. For engineers Don’t accept the claim. Check the process flow diagram. Check the mass balance. Check the energy balance. Check the capture efficiency, conversion efficiency, purge streams, losses, auxiliary energy and make-up requirements. Does the balance close? For policymakers Don’t begin with labels. Ask: How much fresh geological carbon enters the defined boundary? How much carbon leaves for the atmosphere? How much is recovered and circulated? What energy must continuously enter from outside? This provides a physical basis for distinguishing decarbonisation from defossilisation. For investors The questions become equally straightforward. Can the system provide dispatchable energy over infrastructure-scale operating life? Can operational carbon emissions be reduced to very low levels? Can dependence on continuous fresh geological-carbon supply be progressively reduced toward the make-up required for unavoidable losses? And can all of this be demonstrated economically at commercial scale? If so, the investment question becomes worth examining. The CRT proposition is testable We are not asking engineers, policymakers or investors simply to believe that CRT leads toward defossilisation. Define the boundary. Follow the geological carbon. Follow the energy. Check the balances. If the balances do not close, challenge the proposition. If they do close, follow the logic to its conclusion. That conclusion is defossilisation. #FollowTheCarbon #FollowTheEnergy #Defossilisation #CarbonRecycling #CRT #Thermodynamics #EnergyTransition #CircularCarbon #CleanEnergy #IndustrialDecarbonisation
