Airrane

Airrane (Korean: 에어레인, stylized AIRRANE) is a South Korean company built around gas separation membrane technology. According to its official website, the company positions itself as a leader in carbon dioxide capture (CCUS), biogas upgrading, and nitrogen and oxygen purification — three application areas that all rest on the same core competency: engineering membranes that selectively separate gases. Rather than selling a consumer product, Airrane operates in the industrial and clean-energy equipment space, supplying membrane-based systems and related technology to customers who need to capture CO2, upgrade raw biogas into pipeline- or vehicle-grade biomethane, or produce purified nitrogen and oxygen streams. The company is described in Korean-language reference sources simply as "a South Korean gas separation membrane company" (대한민국의 기체 분리막 기업). Its public identity is therefore that of a specialized technology firm rather than a diversified conglomerate: the membrane is the product platform, and CCUS, biogas upgrading, and gas purification are the commercial expressions of it. This places Airrane in the broader carbon-capture and industrial-gas value chain, alongside engineering firms, gas majors, and other membrane and adsorption technology providers. A notable publicly reported technical achievement came in 2025, when Airrane worked with Korea Hydro & Nuclear Power (한국수력원자력) and Doosan Fuel Cell (두산퓨얼셀) to capture more than 90% of the carbon dioxide emitted from a PAFC (phosphoric acid fuel cell) — described as the first such result in South Korea. That project illustrates how the company applies its membrane technology to real decarbonization use cases rather than only laboratory demonstrations. Airrane maintains an official website at airrane.com, which carries corporate information, notices, and descriptions of its technology focus. The company is not known to be a listed public company based on the available evidence, and details such as its founding year, headquarters address, ownership structure, and executive leadership are not established by the supplied sources. What is clear is its sector: gas separation membranes for carbon capture, biogas upgrading, and industrial gas purification, with a growing track record in Korean decarbonization partnerships.

Airrane (Korean: 에어레인, stylized AIRRANE) is a South Korean company whose business is organized around gas separation membrane technology. Korean-language reference material identifies it plainly as "a South Korean gas separation membrane company" (대한민국의 기체 분리막 기업), and its official website describes it as a company leading the fields of carbon dioxide capture (CCUS), biogas upgrading, and nitrogen and oxygen purification on the basis of that membrane technology. The company's development path is therefore best understood through its technology applications rather than through a long corporate chronology. Gas separation membranes work by allowing some molecules in a mixed gas stream to pass through a membrane material faster than others, producing a permeate enriched in the faster gas and a retentate enriched in the slower one. Applied to flue gas or process gas, this principle supports carbon dioxide capture; applied to raw biogas, it supports upgrading to biomethane; applied to air, it supports production of purified nitrogen or oxygen. Airrane's public materials present all three as core lines of business, indicating that the company has built a membrane platform and then commercialized it across several end markets rather than pursuing a single application. A significant, publicly reported milestone came in 2025, when Airrane collaborated with Korea Hydro & Nuclear Power (한국수력원자력) and Doosan Fuel Cell (두산퓨얼셀) to capture more than 90% of the carbon dioxide emitted from a PAFC (phosphoric acid fuel cell). The result was described as the first of its kind in South Korea. The project is notable both for its performance figure and for its partners: a national power utility and a fuel-cell manufacturer, which places Airrane in the Korean clean-energy and decarbonization ecosystem rather than only in the general industrial-gas equipment market. Beyond these points, the supplied evidence does not establish Airrane's founding year, founders, headquarters location, ownership, or listing status. Its official website (airrane.com) serves as the primary corporate channel, carrying company information, notices, and technology descriptions. The company is active and continues to present itself as a specialist in membrane-based gas separation for carbon capture, biogas upgrading, and gas purification.
