Biofuel Electrosynthesis Renewable Diesel & Sustainable Aviation Fuel

A patented electrified process converts waste feedstocks into zero-emissions Renewable Diesel and Sustainable Aviation Fuel (SAF). Using Australia's abundant low-cost renewable electricity, Re.Fuel stores clean energy as drop-in liquid fuels — decarbonising freight, aviation, and maritime transport without requiring engine retrofits.

Plasma Electrolysis & Carbon Recovery Zero-Emissions Green Steel

A patented electromagnetic (EM) plasma process splits CO₂ directly into elemental carbon and oxygen — recovering carbon as a valuable material rather than an atmospheric pollutant. Applied to iron refining, this breakthrough enables the production of green steel with genuinely zero carbon emissions from the furnace.
