Nittera CO2 Recovery Project Targets 2,000 Tons Yearly

Nittera Begins Three-Company CO2 Recovery Demonstration

Nittera CO2 Recovery efforts will expand through a new demonstration involving Nittera Co., Ltd., Hitachi Plant Services Co., Ltd., and Koatsu Gas Kogyo Co., Ltd. The companies plan to begin testing in October, covering the separation, collection, liquefaction, and sales of carbon dioxide emitted from plants. Nittera will provide the CO2 recovery and capture system, while Hitachi Plant Services will supply the CO2 liquefaction system. Koatsu Gas Kogyo is joining the project through its industrial gas supply and sales network, creating a three-company framework intended to develop practical carbon recycling capabilities for plant exhaust gas.

Komaki Plant to Support System Optimization

Nittera Co., Ltd. plans to conduct the demonstration at its Komaki Plant in Komaki City, Aichi Prefecture, where the company intends to optimize its CO2 recovery system and accumulate operational know-how. The testing is designed to provide practical experience across the collection and liquefaction process while supporting the subsequent sale and utilization of recovered carbon dioxide. Nittera is targeting commercial provision of approximately 2,000 tons of CO2 per year beginning in April 2027, making the Komaki operation an important step toward establishing the capabilities required for the planned commercial service.

Companies Build on Existing CO2 Technology Cooperation

The collaboration builds on an agreement reached in May 2025 between Hitachi Plant Services Co., Ltd. and Nittera to begin a joint demonstration involving the collection, liquefaction, and local utilization of CO2 emitted from plants. Since then, the companies have worked on technologies needed for the process. The latest agreement expands that cooperation by bringing in Koatsu Gas Kogyo Co., Ltd., whose industrial gas supply and sales network can support the commercial handling and distribution side of the initiative.

Local Production and Consumption Model Targets Carbon Recycling

The three companies intend to use the demonstration to develop a local production and local consumption model for carbon dioxide recovered from plant exhaust gas. The approach connects CO2 recovery and capture with liquefaction, sales, and local utilization rather than treating captured emissions solely as a disposal challenge. By coordinating equipment capabilities with an established industrial gas network, the partners aim to build operational knowledge and establish a practical pathway for recovered CO2. The companies also state that these activities are intended to contribute to reducing CO2 emissions while creating a carbon recycling model centered on locally recovered plant exhaust gas.

Commercial CO2 Supply Planned for April 2027

Nittera is targeting commercial provision of about 2,000 tons of CO2 annually from April 2027 after the demonstration and system optimization work. Reaching that target will depend on the companies establishing reliable operating procedures for separation, collection, liquefaction, and sales during the demonstration period. The project therefore links technical validation with the development of a commercial supply model. Its planned structure also gives Koatsu Gas Kogyo a role in connecting recovered CO2 with industrial gas distribution capabilities, while Nittera and Hitachi Plant Services continue to contribute recovery and liquefaction technologies, respectively.

Industry Impact & Outlook

The initiative illustrates how industrial CO2 management can combine recovery equipment, liquefaction technology, and established gas distribution capabilities within a localized business model. For Japan, the project could provide practical operating experience for using recovered plant emissions as a resource while reducing dependence on separated functions across different suppliers. The next major steps are the October demonstration, optimization at the Komaki Plant, accumulation of operational know-how, and preparation for the planned April 2027 commercial supply. The outcome will help determine how effectively the three-company structure can support recurring CO2 recovery, liquefaction, sales, and local utilization at the targeted scale.

Frequently Asked Questions

When will Nittera's CO2 recovery demonstration begin?
The three-company demonstration is planned to begin in October and will focus on recovering and liquefying carbon dioxide emitted from plants for subsequent sales and local utilization. Nittera will conduct system optimization at its Komaki Plant in Aichi Prefecture while the participating companies build operational know-how. The project brings together Nittera's CO2 recovery and capture system, Hitachi Plant Services' liquefaction system, and Koatsu Gas Kogyo's industrial gas supply and sales network as part of a broader carbon recycling initiative.

How much CO2 does Nittera plan to provide commercially?
Nittera plans to begin commercially providing about 2,000 tons of CO2 per year from April 2027 following the demonstration and optimization activities. The planned commercial model is intended to connect recovered plant emissions with liquefaction, sales, and local utilization. The companies are also working toward establishing a local production and local consumption carbon recycling model for plant exhaust gas. The demonstration is expected to help the partners accumulate operating experience and establish the technologies and procedures needed to support the planned annual supply.
