Carbon emissions from shipping account for about 3 per cent of global ghg emissions. In the context of global carbon reductions, how the shipping industry reduces carbon is an important issue。
“a ship's motorization will be an advantageous path to carbon decarbonization in inland coastal waters for a considerable period of time now and in the future.” on 6 june, the general manager of the department of strategic development, green water new flight technology ltd. (hereinafter referred to as “green water technology”), koji, spoke to a journalist at the shanghai international carbon middle fair (www. Thepaper. Cn)。
It was described that green water technology was organized by the china ocean shipping group's joint recruitment bureau group, china's can build-up and china's chongchong unit, with the aim of promoting the electricization of ships in the coastal waters of the inland river。
On 28 december of last year, two electric container vessels of the 700 teu class along the yangtze main line of the midway sea were successfully named in yangzhou. It is currently the maximum global capacity and maximum power of electric vessels, and it was also selected as the weight of the central enterprise of the ten majors in 2023。
According to the high poetry, “the 700 teu class electric container ship, which is built and built by our own design and owns an autonomous intellectual property right, can carry a maximum of 36 20-foot standard container-sized box batteries, and can be deployed flexibly according to the voyage and the hydrological and cargo conditions”
“an electric vessel is expected to be `zero emissions, zero pollution and zero noise' during its operation in conjunction with green electricity compared with conventional fuel vessels.” according to high poetry, the 700 teu class electric container ship was the first green zero carbon-smart pilot vessel to transport the yangtze main line container. It was indicated that a single 700-teu-class electric container vessel was expected to reduce co2 emissions by nearly 3,000 tons a year。
The high poetry suggests that the current reduction of carbon decarbonization in the shipping industry is a major development, with relatively short distances and low loads along the inland coast, and the electricization of ships as an advantageous path. In the inland coastal shipping industry, the advantage of motorization of ships compared to other green alternative fuels is that battery costs are significantly reduced, port facilities are well equipped, zero carbon operations are expected and shipowners are more acceptable。
“at this stage, the operating system for electric ships is already of a preliminary economic nature.” it emphasizes that “the cost of lithium batteries has decreased by about 90 per cent over the past decade or so as battery technology has evolved and designs have been optimized, leaving a certain amount of space for future tank batteries”
According to data from the institute of advanced industrial and industrial research (ggii), the cost of lithium batteries decreased by more than 40 per cent in 2023 compared to 2022, with lower prices of raw materials and spare parts expected to decrease by 5-10 per cent and the cost of lithium batteries by 0. 03 /wh - 0. 06 /wh on the available basis。
For how to ensure the safety of electric ships? The expert from green water technologies and green energy operations said to journalists, “the demand for batteries as a whole is high on electric ships. In terms of the design of the battery structure, we met the operational requirements of the ship through a number of safety experiments.”
With regard to ensuring the safe operation of the recharge power plant, hou adong explained that green water technology had developed a series of operational protocols and safety regulations. At the same time, staff at various points were trained accordingly. The security of charging station equipment and facilities is also ensured from multiple angles through the establishment of intelligent systems such as cloud platform systems and integrated management systems。
“from the point of view of the operation of electric ships, it is very important to coordinate the `node' of the ship's operations and the charging of electricity.” when a 700-teu-class electric container ship is in port, the loading and unloading operations can be accompanied by the replacement of box-based power, like the suspension of ordinary cargo。
In addition, in terms of electricity use strategies, hou adong indicated that, depending on the range of the voyage, ships could also be flexible in terms of the number of batteries and the length of charge and the length of the remaining miles。
“long distance, large tonnage, trans-provincial operation, straight-to-water projects such as the 700-teu class electric container ship are demonstration poles for the current ship's motorization industry.” the high poetry suggests that in the future, the green water technology ship's electrodynamic solution will be further extended to the country's main inland and coastal waters, providing experience in reducing emissions from domestic river and coastal shipping。
“the electric ship project has helped to build a new shipping energy package centred on green electricity, promoted clean energy applications in our domestic river port industry and contributed to the upgrading of the green transformation of our domestic river coastal shipping industry and helped build our new energy infrastructure network.”。
It is noteworthy that the global “carbon tax” on shipping will reach, or further drive, industries to reduce carbon。
Last year, the global maritime organization (imo), the regulatory body for shipping, adopted the greenhouse gas reduction strategy for ships 2023, specifying that by 2030, total annual emissions of greenhouse gases from international maritime transport would be at least 20 per cent lower than in 2008 and 30 per cent lower; by 2040, total annual emissions of greenhouse gases from international maritime transport would be at least 70 per cent lower than in 2008 and 80 per cent lower; and by 2050, net emissions of greenhouse gases would be zero。
In march this year, during talks organized by imo, 34 countries supported the introduction of a fee for greenhouse gas emissions from shipping, which is expected to be adopted by imo next year。
In addition to the eu's integration of the shipping industry into the carbon trading system (eu ets), there is an urgent need to reduce emissions from ship-saving emissions。
It is stated that the international ship carbon tax is mainly concerned with the loss of carbon from oceanic shipping, but that the current demand for carbon reduction has been channelled from oceanic shipping to inland shipping, addressing the greening of inland coastal basins and contributing to the “greening of the whole course” of shipping。
