Ammonia mixing for future storage technology -Lithium - Ion Battery Equipment

JGC and the National Institute of Advanced Industrial Science and Technology of Japan have demonstrated a system that uses solar energy to generate hydrogen, then converts it into ammonia in an energy-saving way, and then uses it for power generation through combustion in gas turbines. This process is "CO2 from production to power generation free," read the joint press statement.

JGC indicated that a ruthenium based catalyst has been developed to synthesize ammonia from hydrogen and nitrogen at low temperature and high pressure. The press statement said that ammonia is an "ideal hydrogen energy carrier", partly because the use of hydrogen as a fuel will cause "problems of cost and safety, [and] transportation and storage efficiency." Ammonia also contains large amounts of ammonia. Hydrogen, which is easy to liquefy, has been widely used as fertilizer, which means that the supply chain is in place. “(Lithium - Ion Battery Equipment)

The new method of JGC ammonia production is shown in the figure below, compared with the traditional process at the bottom:

According to the data of American Energy Storage Association, for the round-trip efficiency, the first step of hydrogen production through electrolytic water may soon reach as high as 90% efficiency. As for the second step of converting hydrogen into ammonia, JGC did not disclose the efficiency of its process, but the third and final step of burning ammonia. The research report of Hideaki Kobayashi of Northeastern University shows that the thermal efficiency of burning ammonia air mixture is close to that of burning methane (natural gas) and air mixture; NOx emission is reduced through selective catalytic reduction.

According to the joint statement of JGC and the National Academy of Advanced Industrial Sciences, Japan intends to create an "innovative low hydrocarbon fuel economy" by 2030, and through its energy carrier research of "playing a leading role in hydrogen related industries in the world market".

Australia is also evaluating renewable hydrogen, and the Australian Renewable Energy Agency released a report on this topic last August.

At the same time, the British Climate Change Commission pointed out in a report in November that "hydrogen can be produced at low cost... from solar power near the equator. This needs to be imported through ships, or as hydrogen or other energy carriers, such as ammonia." The Commission predicted that, for England, "in the 2030's, burning hydrogen in power plants would be cost-effective for the government's carbon emission price. “

The shipping industry can help achieve the scale of converting renewable energy into ammonia. International Renewable?? In a report in April 2018, the Energy Agency said that its "general proposal on the development of P2X [renewable energy fuel] is to focus on ammonia development and long-distance road transport in the shipping industry. Few or no competitors have low-carbon technologies. It is expected that P2X is economically feasible.
