MHI has joined the Clean Energy Precinct project in Newcastle, Australia, and will leverage its experience developing the Takasago Hydrogen Park in Japan. Located adjacent to the world’s largest coal port, the Clean Energy Precinct will feature “production, storage, distribution and export” facilities, focused on electrolytic hydrogen and ammonia.

Japanese government funding via NEDO will support four critical ammonia energy projects, including JERA's new plan to demonstrate 50% ammonia-coal co-firing by 2030. Other projects include improved catalysts for ammonia production, low-temperature and low-pressure synthesis pathways, and developing 100% ammonia-fed boilers and gas turbines. In addition, a new cooperation agreement between ASEAN countries will see Japan support other members to adopt their ammonia energy solutions, particularly coal co-firing.

A series of announcements from Mitsubishi Hitachi Power Systems this year shows the breadth of the company’s efforts to prepare for the energy transition. MHPS is a prominent global supplier of large gas turbines for power generation, and is a member of Japan’s Green Ammonia Consortium.

Chief executives of major corporations are now talking about ammonia energy. This represents another crucial step up the learning curve for clean industry: knowledge about ammonia's potential has successfully spread from the R&D department to the executive suite. This is the difference between development and deployment. The fertilizer industry saw this in 2018, when the CEOs of first movers like Yara and OCP announced green ammonia pilot plants. These latest announcements come, however, from the shipping and power sectors — far bigger industries, with no existing ammonia business — and they focus on the use of green ammonia: for fuel and for profit.

Approximately 40% of the world’s energy budget is consumed in the generation of electricity.  This is by far the largest use of primary energy across major energy-consuming sectors (transportation, industry, etc.).  What role ammonia will play in the electricity sector is therefore a question of considerable importance for the sustainable energy system of the future.  One concept currently on the table is power-to-ammonia as a means of electricity storage, whereby electricity is used to produce hydrogen and the hydrogen is reacted with nitrogen to produce ammonia.  The other, mirror-image, concept is to use ammonia, or hydrogen derived from ammonia, as a fuel that can be turned into electricity. This “back-end” use case is the focus of recent announcements from Mitsubishi Hitachi Power Systems (MHPS).  According to an April 5 story in the Nikkei Sangyo, MHPS plans to put a “hydrogen-dedicated gas turbine . . . into practical use by 2030.”  The company also stated that it has “started developing technology to extract hydrogen from ammonia,” citing ammonia’s ease “to store and transport.”
