Intrinsic Combustion, Storage, and Compatibility Stability in Fuels: A Structural Admissibility Condition for Fuel Identity and Industrial Deployability

Description (Abstract) This document establishes intrinsic combustion, storage, and compatibility stability as a necessary structural admissibility condition for fuels—whether alternative, synthetic, bio-derived, electro-derived, hybrid, or petroleum-derived—that claim functional performance, safety, compatibility, durability, or industrial deployability. The analysis is strictly non-constructive and does not disclose any compositions, formulations, additives, blending ratios, refining steps, synthesis pathways, catalysts, conditioning methods, infrastructure requirements, or operating conditions. Instead, it formalizes a boundary condition under which a claimed fuel must preserve its functional identity and claimed properties within an intrinsic stability envelope, rather than through conditioning, additive dependence, consumptive mediation, logistics rituals, or infrastructure-dependent mitigation. This condition constrains patentability at the level of enablement, inventive step, and industrial applicability and applies uniformly across all fuel classes. This document functions as prior art defining admissibility, not as a technical teaching.
