Tesla remains self-absorbed with EVs, and Japan is developing a powerful hydrogen<\/strong> industry rivaling South Korea. But what if we found an even better fuel? That’s what an international team of experts has come up with, with a proposal that we don’t know about in America and that, while they’ve called it “dangerous,” isn’t dangerous at all. This is the first “freezing\u00a0engine<\/strong>” that shatters all efficiency records with a new type of combustion that we have never seen before.<\/p>\n

This new engine is better than hydrogen. It’s not known in America, but it’s the future<\/h2>\n

The industry will therefore benefit from IHI Power Systems, together with ClassNK\u2019s recent milestone in ammonia-burning, the IHI Low Speed Single Cycle 2-stroke engine. The undertaking started in October 2021 when NYK Line, Japan Engine Corporation, IHI Power Systems, and Nihon Shipyard Consortium were awarded under the Green Innovation Fund Project<\/strong>.<\/p>\n

Its purpose was to design and market a ship with a domestically developed ammonia-fueled engine. The 280 mm bore four-stroke ammonia-fueled marine engine produced IHI Power Systems started a trial operation in its Ota plant in Gunma Prefecture, Japan at the beginning of 2023.<\/p>\n

Experts have tested the first ammonia engine, and these are the results<\/h3>\n

The tests were successful, since the engine could work stably at an 80% ammonia fuel co-firing ratio<\/strong>. Comparing ammonia to hydrogen, the former has several advantages as a marine fuel. Ammonia does not emit CO2 on combustion, and thus its use is probably more friendly to the environment than that of hydrogen.<\/p>\n

Also, ammonia is less problematic in the aspects of storage and transport, since it can be easily liquefied at a comparatively lower pressure. The tests that have been recently performed by IHI Power Systems and ClassNK show very good coefficients, such as these two that we highlight:<\/p>\n
