Commencement of a Study on Diversion of Existing Liquefied Natural Gas Receiving and Storage Facilities for Introduction of Fuel Ammonia in Gas-fired Power Plants
IHI has begun studying the conversion of liquefied natural gas (LNG) receiving and storage facilities (*1) installed near many gas-fired power plants to ammonia fuel (*2) receiving and storage facilities. Did. Utilizing IHI’s knowledge of corrosion and experimental technology related to materials, we will proceed with studies to enable the conversion of existing LNG receiving and storage facilities with minimal modifications, aiming for social implementation in the latter half of the 2020s.

Expectations are rising for ammonia, which does not emit CO2 when burned, as a carbon-neutral option not only for coal-fired power plants but also for gas-fired power plants. IHI uses ammonia as fuel for boilers and gas turbines. We are developing the technology. In addition, the introduction of carbon-neutral fuel will require the development of receiving and storage facilities, but the diversion of existing LNG receiving and storage facilities will lead to significant cost reductions and effective use of land, leading to the promotion of introduction. Expected.
IHI is Japan’s top manufacturer, with a track record of designing and constructing approximately 30% of LNG receiving and storage facilities and approximately 50% of LNG storage tanks. As for large-scale storage tanks, we have a track record of building 250,000 KL tanks, one of the largest in the world. Utilizing these technologies, we are proceeding with the comprehensive development of a large-scale ammonia receiving terminal, including storage tanks.
In the future, IHI will continue to contribute to the realization of a carbon-neutral society by promoting the construction of a fuel ammonia supply chain in order to develop fuel ammonia utilization technology and respond to future increases in demand.
(*1) Receiving/storage facility: A facility that receives and stores liquefied fuel, etc. transported by ship from Japan and overseas, regasifies it according to demand, and delivers it to a consumer such as a power plant through a pipeline.
(*2) Features of fuel ammonia:
Ammonia (NH3) contains hydrogen in high density and is easy to handle, making it a highly efficient and low-cost means of transporting and storing hydrogen energy (an energy carrier). It can also be used directly as a fuel for thermal power generation. It is also possible. Since it is already widely used as a raw material for fertilizers and chemical products, a consistent technology for manufacturing, transportation and storage has been established. Since it does not contain carbon and does not emit CO2 when burned, it is expected to be a promising fuel for decarbonization in the power generation field. ■ Reference information
