Mitsui & Co. and JERA announced that they have been awarded CfD funds by the Japanese government to support the import of CCS-based ammonia from the Blue Point project in Louisiana, USA. By 2030 (2029 in JERA’s case), full supply chains will be established to import the ammonia into Japan, for use in the power generation, cement manufacturing, and other industrial sectors.

Despite the successes and progress made in 2025, the year remains a missed opportunity for ammonia energy. The first complete supply chains for renewable ammonia are emerging, and some 600,000 tons of annual production capacity is set to be online in northeast China early next year. Maritime engines, cracking, and power & heat technology solutions also made their mark, moving from feasibility into deployment. But disappointing outcomes at the IMO and government support that failed to spark market development remains an issue, with plenty of critical, detail-heavy work ahead of us in 2026.

Evaluation of the Cement Clinker Fired in the Combustion Furnace of Heavy-Oil and NH3
Presentation

In recent years, global warming caused by an increase in CO2 emission released by combustion of fossil fuel has become a big problem. To realize a low-carbon society, active use of renewable energy and promotion of hydrogen energy are necessary. We are participating in “SIP (Strategic Innovation Promotion Program) energy carriers”, developing technology to replace 30% fossil fuel with ammonia (NH3) on the calorie basis. Assuming that NH3 is used as a thermal energy for a cement kiln, we conducted the following two basic experiments. First, we fired the clinker in the atmosphere-controlled electric furnace, calculated the reaction rate of…

Simulation Analysis of NH3 Mixed Combustion in Clinker Manufacturing Process
Presentation

Recent years, the action for the low-carbon society becomes active all over the world. NH3 has potential to become the free-carbon energy source. In SIP project, that Cabinet Office started, we work on the technology development applying NH3 to the field of industrial furnace (SIP: Strategic Innovation Promotion Program). In this study, we evaluated the effect of NH3 use in the cement clinker manufacturing process. Cement manufacturing is one of the fields of industry to exhaust large amounts of CO2. As past works, we studied for the reduction of heat consumption rate, troubleshooting and so on by using kiln operation…
