Rethinking the future of clean fuels starts with closing the carbon and hydrogen loops right at the source. 🌍⚙️

The energy transition demands drop-in liquid fuels that can decarbonize aviation, marine, and heavy transport without waiting decades for new infrastructure. However, scaling e-fuels has long faced two major bottlenecks: the high cost of external green hydrogen transport and storage, and inefficient carbon utilization.

At BioCom, we are engineering a direct, closed-loop solution: Regenerative Alkanes synthesized from CO2 and H2 with in-situ hydrogen generation.

Here is how our integrated reactor architecture transforms emissions into high-value fuels:

1️⃣ In-Situ H2 Generation (Fe–Fe3O4 Redox Cycles) : Instead of relying on costly external hydrogen logistics, a dedicated Steam-Iron reactor generates pure H2 on-site through cyclic oxidation and reduction of iron oxide.

2️⃣ Tandem CO2 Fischer-Tropsch Synthesis: Captured CO2 and in-situ H2 enter a shell-and-tube fixed-bed catalytic reactor, driving the reaction CO2 + (3n+1)H2 —> CnH(2n+2) + 2nH2O to build long-chain saturated alkanes.

3️⃣ Closed-Loop Water Recovery: Byproduct water (H2O) from the synthesis stage is recycled directly back into the Steam-Iron reactor to sustain continuous H2 generation—maximizing mass balance efficiency.

4️⃣ Precision Fractional Distillation: The resulting syncrude is separated into drop-in Gasoline, Sustainable Aviation Fuel (SAF), and Renewable Diesel.

Environmental performance isn’t a cosmetic layer—it is an engineering constraint. By integrating in-situ hydrogen production with catalytic carbon conversion, we turn industrial emissions into circular energy value streams.
