Carbon Xtract m-DAC Membrane Module

Carbon Xtract Corporation is a Kyushu University spin-off with a Japanese and English website, working on CO2 capture from the air and its use. Its stated aim is a society where anyone can contribute to decarbonization anytime, anywhere. The site does not state a founding year or address.

Its m-DAC is a compact, decentralized direct air capture module that uses gas separation nanomembranes developed at Kyushu University. It selectively captures CO2 without heating, which allows miniaturization and modular installation, and conversion units can be connected to move toward carbon fuel production. A June 2026 announcement covers a demonstration of a small distributed DAC system for urban buildings.

• m-DAC module: compact decentralized direct air capture unit.
• Gas separation nanomembrane: technology developed at Kyushu University.
• No heating: simple structure that allows miniaturization and modular use.
• Conversion add-ons: electrochemical or thermochemical units for carbon fuel production.
• Urban building demonstration: small distributed DAC system announced June 2026.

Property developers and building operators in Vietnam can pilot rooftop or HVAC-integrated CO2 capture. Universities and research institutes can collaborate on membrane-based DAC research. Industrial parks can test on-site CO2 supply for downstream use.

The membrane module needs no heating, which reduces energy needs and allows compact installation. Decentralized units can be placed near the point of CO2 use, including urban buildings. Conversion units can be added for carbon fuel production. The company is seeking business collaboration partners.

Direct air capture is moving from large central plants toward compact, decentralized modules that use less energy. Membrane-based capture is an emerging approach, and Asian research spin-offs are attracting early funding. Vietnam's dense cities and industrial parks could host small-scale capture pilots.

Pre-Series A first close on 18 August 2026 with Femto Partners, GxPartners and Kyushu University as investors. Awards listed on the site include the 16th Chikugin Bio Venture R&D Grand Prize (September 2026) and GX Venture Award (October 2025).
