CarbonNest Inc. (CEO: Kei Kawasaki, Headquarters: Bunkyo-ku, Tokyo), an energy startup developing and operating DAC (Direct Air Capture) equipment that directly captures CO2 from the atmosphere, has announced that it has moved into "SUISO no MORI hub" (Komaki City, Aichi Prefecture, within Niterra's Komaki Plant), the demonstration field for the "Suiso no Mori" project promoted by Niterra Co., Ltd. (President: Keiji Suzuki, Headquarters: Higashi-ku, Nagoya, formerly NGK Spark Plug Co., Ltd., hereinafter referred to as Niterra), and has commenced a demonstration test using a small-scale DAC device. ▲ Demonstration experiment at SUISO no MORI hub ■ Background In addition to soaring prices of fossil fuels and chemical products, some industries face structural limitations in reducing CO2 emissions, making the establishment of technology to directly "remove and capture" CO2 from the atmosphere an urgent necessity. CarbonNest has set its business vision as "CO2 into Energy—Transforming Carbon Dioxide into a Force to Drive Regions," and has been working to create a system for circulating captured CO2 as regional electricity, fuel, and industrial resources. Now, by participating in Niterra's "Suiso no Mori" project, which aims to create new businesses through co-creation with startups possessing innovative technologies, a demonstration through collaboration between the two companies has begun. ■ CarbonNest's Strengths CarbonNest's strength lies not only in the development of DAC hardware but also in its operational control technology that optimally controls the system according to the local energy environment and the intended use of the captured CO2. CarbonNest enables the operation of DAC in diverse environments, allowing for stable and efficient CO2 capture. Demonstration Overview The small-scale DAC device used in this demonstration achieved over 200 hours of continuous stable operation outdoors in Ishikari City, Hokkaido, from November to December 2025. This device will
