Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Progress in Chemical Engineering Equipment】Regular updates and summaries are available; feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On March 28th, China’s first domestically developed medium-speed engine for methanol fuel ships, which features a high degree of substitution potential, was officially delivered, and orders for 8 more such engines were placed. This type of engine was entirely developed independently by the 711th Research Institute of CSSC. The engine has a cylinder diameter of 210 millimeters, a rated speed of 1000 revolutions per minute, and a rated power of 1000 kilowatts. It utilizes direct methanol injection technology, and is equipped with a highly compact dual-fuel injection system developed independently as well as an intelligent control system for flexible fuels. The proportion of methanol used can exceed 90%, reaching up to 95% in some cases. It is reported that by using green methanol, a single medium-speed engine for methanol-fueled ships can reduce carbon emissions by over 5,000 tons per year, while cutting nitrogen oxide emissions by 60% and sulfur oxide emissions by up to 99%. The successful delivery of this type of methanol-fueled medium-speed engine provides critical technical support for China to achieve its \"dual carbon\" goals. In October 2024, this type of engine passed the classification society’s type testing, thereby obtaining China’s first type approval certificate for medium-speed marine engines powered by methanol fuel with a high substitution rate. Recently, the CS27DF-A ammonia fuel engine, developed in conjunction with methanol fuel engines, has also passed the type approval by the China Classification Society, with an ammonia fuel substitution rate of up to 85%. The first batch of methanol-fueled medium-speed engines delivered this time will be used as propulsion engines on the 130-meter methanol-powered Chuanjiang standard bulk carriers operated by Shanghai Yangtze River Shipping Co., Ltd., thereby helping to accelerate the commissioning of the first large-scale fleet of clean ships operating on the Yangtze River waterway. The shipping industry handles around 80% of the world’s trade shipments, and its carbon emissions have been a focus of concern for the international community. Currently, LNG, green methanol, green ammonia, and green hydrogen are considered the main alternative energy sources for addressing carbon emission reduction. Among them, green methanol fuel is highly favored due to its low-carbon potential throughout its life cycle, as well as advantages in storage, transportation, and refueling; it is one of the preferred fuels for achieving the medium-term decarbonization goals of the shipping industry in the future.
