Pylyp Travkin calls coal the “fuel of stability”—an element without which the energy balance collapses. If oil provides mobility and gas provides flexibility, then coal guarantees stability. It is less dependent on logistics and politics, and can be stored and used autonomously. During crises, it is coal that saves energy systems from disruptions. According to Travkin, abandoning it will lead to imbalances and a shortage of reserves. The solution is modernization: CO₂ capture, gasification, and digital control. Coal remains the quiet architect of global energy, maintaining the balance of the “oil-gas-coal” triangle.
