Development of canned motor pump for liquid ammonia

EBARA Corporation has developed a canned motor pump for liquid ammonia, which is expected to be a carbon-free fuel.

Amid the global trend toward decarbonization, research is underway, primarily in Japan, to use ammonia, which does not emit CO2 when burned, as an effective fuel for combating global warming. While ammonia is attracting attention as an energy carrier for transporting Hydrogen, it is toxic and has an odor, so it is important to prevent its leakage to the outside when handling it.
As ammonia becomes more widely used as a fuel in the future, the market is calling for safer ways to transport it, so we have been developing a pump with a new structure that prevents the handled liquid from leaking to the outside.

The pump developed this time can be used in facilities that handle fuel ammonia. By adopting a submerged structure for liquid ammonia to the motor portion, ammonia liquid can be transported without leaking to the outside. Going forward, this system will contribute to safer ammonia liquid transport at facilities such as ammonia fuel terminals and ammonia fuel power plants.

With the aim of reducing greenhouse gas (CO2) emissions from thermal power plants, numerous ammonia co-firing plants are being planned, and demand for leak-free pumps is expected to increase.
We will accelerate our efforts to achieve carbon neutrality by 2050 and contribute to the realization of a sustainable society as outlined in our long-term vision, "E-Vision 2030."　

The EBARA Group will address material ESG issues based on its long-term vision and medium-term management plan in order to achieve the Sustainable Development Goals (SDGs) and further increase its corporate value.
