Energy additives

Yes. But there is no scientifically recognized list of exactly 999 “energy additives.” The term can cover fuel additives, lubricant additives, catalyst components, battery additives, corrosion inhibitors, heat-transfer additives, and process chemicals.

For industrial use, it is better to organize them by energy application and chemical formula, rather than mixing them together.

Important: Some entries are fuels or process chemicals rather than “additives” in the narrow sense. Also, materials such as Pt, Pd, NiMo/Al₂O₃, CoMo/Al₂O₃ and zeolites should be used in engineered reactors/process units—not added directly to LPG or fuel cylinders.

If you're building Sahara Energy's industrial catalogue, I can structure a much larger 999-item database into Fuel additives 1–200, catalysts 201–400, battery/energy-storage additives 401–600, hydrogen/gas-processing chemicals 601–750, lubricant additives 751–850, and renewable/industrial-energy materials 851–999, with formula + CAS number + application + SDS/COA requirement + Saudi compliance field.
