CloudAir Acquires 'Patent Technology for Reducing Greenhouse Gases in the Air Linked to Renewable Energy'... "Accelerating New Carbon Reduction Business"

[Asia Economy Reporter Hyunseok Yoo] CloudAir announced on the 13th that it has signed a patent technology transfer agreement for an 'airborne greenhouse gas reduction device' with Ajou University Industry-Academic Cooperation Foundation.

Recently, more than 70 countries, including South Korea, have declared '2050 Carbon Neutrality.' To curb climate change caused by global warming from greenhouse gases, they have set a common goal to reduce carbon dioxide (CO2) emissions by 50% compared to 2013 levels by 2050 and to limit the global average temperature rise to below 2℃ by 2100, realizing the 2DS (2℃ Scenario). The government introduced a carbon emissions trading system in 2015, allocating carbon emission quotas to each company. According to the company, as emission quota management becomes stricter following the 2050 carbon neutrality declaration, greenhouse gas reduction patent technologies are gaining attention.

The patented technology is a type of renewable energy-linked greenhouse gas reduction hybrid technology. Unlike existing technologies that reduce CO2 in industrial exhaust gases, it introduces a new DAC (direct air capture) technology that directly absorbs and processes very low concentrations of CO2 exceeding 400 ppm from the atmosphere. The driving power required for equipment operation is supplied from renewable energy (carbon-neutral, CO2-neutral), realizing carbon dioxide reduction, making it a promising and genuine greenhouse gas reduction technology for the future. The renewable energy-linked DAC technology currently corresponds to an international standard that can be recognized for actual carbon emission rights.

Additionally, by utilizing the patented technology, it is possible to reduce not only atmospheric carbon dioxide but also non-CO2 greenhouse gases such as methane and nitrous oxide. The carbon dioxide captured through an alkaline solution can also be used to produce and sell hard calcium carbonate (CaCO3) through mineralization, which is internationally recognized for carbon reduction. Hard calcium carbonate can be industrially used for various purposes such as calcium supplements in health functional foods, pharmaceuticals and feed excipients, bio-plastic stiffeners, pulp, and dyeing.

A CloudAir official said, “With the acquisition of this transferred patent, we will accelerate our new business in greenhouse gas reduction and do our best to commercialize eco-friendly carbon reduction green technologies.”
