Biogenic Direct Air Capture

Carbon removal supported by clean hydrogen from a single process

The Integration of Photosynthesis & Industrial Reforming

B-DAC stands for Biogenic Direct Air Capture. It is TO Viridi’s integrated technology for capturing atmospheric CO₂ and producing clean hydrogen simultaneously.

The core insight: Bio-Renewable ethanol already contains atmospheric carbon. The corn plant pulled that CO₂ out of the air through photosynthesis. When TO Viridi reforms that ethanol into hydrogen, the CO₂ released is atmospheric CO₂ being re-captured, not fossil carbon being emitted.

The ethanol serves as a capture vector, similar to how sorbent or amine solvents work in conventional DAC systems.

One input stream, two valuable outputs.

Surpassing Conventional DAC

Unlike fan-based Direct Air Capture systems which rely on massive energy inputs for air handling and chemical regeneration, B-DAC leverages existing photosynthetic infrastructure at industrial scale.

Pathway to < $0

The sub-zero cost pathway is where B-DAC breaks away entirely. As hydrogen sales revenue grows and module costs decline through manufacturing scale, the net cost attributable to carbon capture goes below zero.

The operation generates positive cash flow from carbon capture before credits are even applied. Pure DAC has no equivalent mechanism or pathway.
