Water-the ultimate fuel.

Water: The Ultimate Fuel In the current energy transition, debates often revolve around electrons versus molecules, hydrogen versus hydrocarbons, or renewables versus fossil fuels. These framings miss a deeper, system-level truth: the ultimate enabler of clean energy systems is neither hydrogen nor carbon, but water. Hydrogen is not a primary fuel. It is an energy carrier derived almost entirely from water. Electrolysis does not create energy; it reorganises water using external energy inputs. The true source material is water itself. Carbon, likewise, is not the enemy. It is a carrier — a stable, information-rich atom that enables energy storage, transport, and dispatchability at scale. When carbon is recycled rather than extracted, it becomes a system asset rather than a liability. Renewable Synthetic Methane Gas (RSMG) emerges as the practical renewable fuel because it unites these roles: hydrogen supplies the energy, carbon supplies the structure, and water closes the loop. Combustion returns the system back to water and carbon dioxide, ready for reuse. Seen through this lens, decarbonisation is not about eliminating carbon, but about using water and renewable energy to clean up a misplaced carbon cycle. Water becomes both the beginning and the end — the origin of hydrogen and the final resting state after energy delivery. Water is the true fuel. Hydrogen carries the energy. Carbon carries the structure. RSMG makes the system work. This is not an invention against nature, but a correction back to it — restoring balance by allowing water to do what it has always done: enable life, energy flow, and renewal.
