In order to implement the national policy of energy conservation and emission reduction and strict environmental protection requirements for special waters, in recent years, clean energy such as solar energy and wind energy has been extensively studied on ships, especially large-capacity lithium-ion batteries as backup energy or direct propulsion energy. received greater attention. Although the electric propulsion vessel is not equipped with an internal combustion engine, which reduces the possibility of fire caused by fuel lines and certain mechanical failures, the battery may cause thermal runaway under abuse conditions such as overcharge, overdischarge, short circuit, high temperature, and collision, and then May bring new fire hazards.

Based on comprehensive consideration of safety performance, cost, energy density and other factors, ternary lithium batteries or lithium iron phosphate batteries are currently selected as marine power batteries.

In order to promote the application of new energy in the shipbuilding industry, the state and local governments have issued some policies for the application of lithium batteries in the shipbuilding industry.

At the national level, although there is no specific incentive policy for battery-powered ships, relevant policies can be found in various documents. On November 30, 2018, the Ministry of Transport issued the “Implementation Plan for Ship Air Pollution Emission Control Areas” to encourage ships to use alternative measures such as clean energy, new energy, on-board power storage devices or exhaust after-treatment to meet the requirements of ship emission control . On January 4, 2019, the Ministry of Ecology and Environment and other 11 ministries and commissions jointly issued the Action Plan for Pollution Control of Diesel Trucks, encouraging the elimination of inland shipping ships that have been in use for more than 20 years, forcibly scrapping shipping ships that have exceeded their service life in accordance with the law, and promoting the use of pure electric and natural gas ships. In September 2019, the Central Committee of the Communist Party of China and the State Council issued and implemented the “Outline for Building a Strong Transportation Country”, with special emphasis on strengthening the application research of new energy in the shipbuilding industry, requiring the promotion of new energy, clean energy and other technical equipment, improving the design and construction capabilities of new energy ships, and strengthening new energy sources. Research and development of cutting-edge key technologies such as energy. In June 2020, the Ministry of Transport issued the “Outline for the Development of Inland Shipping”, proposing to increase the promotion and application of new energy and clean energy, promote LNG energy-saving and environmentally friendly ships, and explore the development of pure electricity, clean fuel and other powered ships.

At the local level, the policies issued by local governments are more targeted. The release and implementation of these policies have greatly promoted the development of the local battery-powered ship industry. For example, the “2018 “Shenzhen Blue” Sustainable Action Plan” formulated by Shenzhen City, the “Guangzhou Port Ship Emission Control Operation Plan (2018-2020)” formulated by Guangzhou City, and the East Lake and other closed waters formulated by Wuhan City prohibit the operation of fuel-fired ships requirements, as well as the forthcoming regulations of Hubei Province prohibiting the operation of fuel-fuelled ships in closed waters.
