Opportunities for the development of new energy for fishing boats
In December 2023, the Ministry of Industry and Information Technology, the National Development and Reform Commission, the Ministry of Finance, the Ministry of Ecology and Environment, and the Ministry of Transport issued the Notice on the Shipbuilding Industry The Notice of the Green Development Action Plan (2024-2030) points out that “promote the pilot project of electrification of coastal inland river ships, actively and steadily promote the research and development and demonstration application of LNG and battery-powered ships such as passenger ships, cargo ships, engineering ships, fishing boats, etc., and promote The research and development and piloting of methanol, hydrogen and other power ship types will be carried out to create standardized and serialized ship types according to the needs of different scenarios. "
The green development of the shipbuilding industry is the basis for a new round of technological revolution and industrial transformation in the global maritime industry. The important direction is the inevitable way for my country's shipbuilding industry to achieve high-quality development. According to data from the "China Fisheries Statistical Yearbook (2023)", there were 342,400 motorized fishing vessels at the end of 2022. The overall technical level of my country's fishing vessels is low, and industry technology updates are slow. Under the future trend of the global climate environment, new energy technology will gradually penetrate into Fishing boats, realize the upgrading of fishing boats and energy systems, and change the situation of old and dilapidated fishing boats in my country.
Exploration on the development of new energy technology for fishing boats
01
New fuel-powered LNG
In 2020, the world’s first battery-LNG hybrid fishing boat Libas was born, as shown in Figure 1. The seine fishing vessel was built by the Cemre Shipyard in Istanbul, Turkey, with a length of 86m and is equipped with a MAN6L51/60DF main engine and Renk
gear box, MANAlpha propeller system and MANCryoLNG fuel gas system, the fuel tank volume is 350 cubic meters.
In 2022, Norway’s Sunny Lady became the world’s second liquefied natural gas fishing vessel. It is 86.5 meters long and 18 meters wide. It was designed by Salt Ship Design and uses liquefied natural gas as the power of the fishing vessel. The innovation of the vessel lies in the hybrid combination of 350 cubic meters of LNG and a 1024kWh battery pack.
2023, Türkiye's Cemre Shipyard built the trawler "Selvag Senior" for Norwegian shipowner Srheim Holding. This ocean seine/trawler is 79.5 meters long, 16.2 meters wide, has a draft of 6.9 meters, and uses a 350 cubic meter LNG storage tank. Liquefied natural gas has become the fuel for the 4800KW Wärtsilä main engine. It becomes the third fishing vessel in the world to use liquefied natural gas (LNG) fuel, after Norway’s Libas and Sunny Lady.
In 2020, CSSC 605 Institute designed the first domestic LNG fuel-powered new ocean-going fishing vessel demonstration vessel "Guangdong Shancheng Yu 16118". The ship is 53.5m long and 8.5m wide. It is a twin-engine, twin-propeller stern slide single trawler. The ship's power system consists of two LNG single-fuel and "LNG-diesel" dual-fuel engines, and is equipped with a 60 cubic meter LNG storage unit. tank, with a cruising range of up to 1,500 nautical miles. The test vessel is mainly used for trawling operations in the South China Sea. The system records the working conditions of the control system and gas power system, obtains key technical indicators such as the fuel replacement rate of LNG-powered fishing vessels, and provides measured data for the economy of subsequent LNG-powered vessels.
In November 2022, CNOOC Gas and Power Group Hainan Branch and the Hainan Provincial Department of Agriculture and Rural Affairs signed a cooperation agreement in Haikou City. It is planned to use LNG power fuel to reach 100 fishing boats within three years, and gradually build It will become a leading and innovative "oil-to-gas" demonstration zone for fishing vessels in the country, and promote the clean energy transformation of fishing vessels in Hainan Province in a step-by-step and phased manner.

Fuel cells Methanol fuel cells
October 2023, World Sailing At the equipment conference, my country’s first methanol fuel cell electric demonstration fishery auxiliary ship was unveiled. This fishing auxiliary ship adopts Zhongke Jiahong’s 6kW methanol fuel cell dual-electric system, equipped with 6kW electric thrusters, and can run for 12-15 hours at a speed of 6-8 knots with 60 liters of methanol fuel. It has zero pollution emissions and long endurance. Mileage, low operating costs, easy to promote and copy and other advantages.
Hydrogen fuel cell
In August 2015, the first hydrogen-fuel-powered fishing boat developed by Japan's Toda Construction Company successfully underwent a trial voyage, as shown in Figure 6. The ship is 12.5m long, can accommodate 12 people, carries 450L hydrogen fuel, can reach a speed of 20kn, and can run for about 2 hours per hydrogenation.
In 2023, the Norwegian fishing boat ‘Skulebas’ became the world’s first fishing boat to sail using green hydrogen, which can achieve completely zero emissions and is scheduled to officially operate in the summer of 2024.
In 2021, China Hydrogen New Energy developed China’s first fuel cell sea fishing vessel, which is equipped with a 30kW fuel cell system. In June 2022, China’s first hydrogen energy powered new material The fishing boat was officially delivered and is currently in good operating condition. The new material ship model for the International Sea Fishing Park developed by Zhongchuang Liangyun, a core company of the China Innovation Materials Shipbuilding Industry Cluster, signed with China Hydrogen (Liuheng) on the construction of the first batch of 20 hydrogen fuel power system fiberglass fishing boat demonstration ships in the country. The cooperation agreement aims to jointly explore the promotion and application of new energy, new materials and new technologies for modern ships.
Power battery
In 2015, Norwegian shipyard Selfa Arctic and Siemens cooperated to build the world’s first A battery-powered fishing boat, the Karoline. This small fishing boat is 11 meters long and is equipped with two battery packs with an overall battery capacity of 195 kWh. It is also equipped with a 500-liter diesel engine, which can provide power guarantee for the fishing boat’s fishing operations in the Norwegian Sea for a whole day.
In July 2020, Qinhuangdao, Hebei Province launched China’s first hybrid recreational fishing boat with battery power, and the first batch of 2 boats was put into use. The total length of this recreational fishing boat is 36 meters, the width is 6.6 meters, and the depth is 2.95 meters. The ship's power system adopts the innovative power system form customized by Wuxi Saisiyi for this leisure fishing boat, which realizes many functions such as diesel main engine, unit and lithium battery pack. organic combination of energy forms.
In January 2024, the aluminum alloy electric fishery auxiliary boat "Yufu 10E 001" developed and built by Ningde Kunpeng Technology Co., Ltd. completed the launch load test. This fishery auxiliary vessel has an overall length of 10.34 meters, a width of 3.4 meters, and a load capacity of 12 tons. It uses pure electric propulsion, has a designed no-load speed of 10 knots, and a range of 15 nautical miles. It has the technical conditions to replace traditional fuel-fired auxiliary boats and meets the requirements of fishermen.
New energy for fishing boatsDevelopment Direction
Although the output power of hydrogen fuel cells and lithium batteries is small and their endurance will be limited by factors such as charging facilities, they have the advantages of low carbon emissions and low pollution. , flexible operation, high work efficiency and other characteristics, it can be applied to small offshore fishing vessels with fixed routes, short voyages, small loads and low battery redundancy requirements.
LNG fuel power has low carbon emissions and high calorific value, which can meet the output of larger power. However, the static capacity density is lower than that of diesel, and the battery life requires frequent refueling. Therefore, it can It is used in fishing boats along the coast and offshore to facilitate refueling.
Whether the application of new energy fishing boats can be accelerated is the key to promoting the green development of fishing boats. With the opening of a new chapter in the rural revitalization strategy of fishing areas, the construction of beautiful fishing villages, and the protection of marine ecological environment, new energy fishing boats will undoubtedly have more expectations placed on them.
