The use of new energy boats batteries in marine boats.
With the improvement of marine emission standards, the use of new green energy in boats has gradually expanded. lithium batteries have gradually become the focus of attention due to their relatively low price, high energy density, and easy maintenance.
The use of new energy lithium batteries in electric boats
In most cases, the boat’s electric propulsion system is powered by an internal combustion engine driven generator set. Due to the complex and changeable marine environment, the load is changing. When the load deviates from the optimal load point, the fuel will not be fully burned, and the utilization rate of the fuel will drop sharply. At the same time, a large amount of nitrogen oxides and sulfur will be generated. oxides, causing pollution to the environment. Marine battery energy storage technology is one of the ways to deal with this problem.
It is beneficial both from an economic point of view and an environmental point of view. In addition, with the development of high-capacity marine battery and supercapacitor technology, the price of energy storage devices will inevitably drop. The prospect of using energy storage units in marine electric propulsion systems is worth looking forward to.
Lithium batteries are widely used, and the era of marine electrification is coming. The discharge pollution of boats is relatively serious. On the one hand, electrification can solve the pollution problem, and at the same time, it has higher economic efficiency. The electrification of boats is the general trend. It is estimated that the demand for marine batteries brought about by electrification will exceed 6.27Gwh in 2025.
There is room for further improvement in the penetration rate of lithium batteries in China’s boats
Electric boats have the advantages of environmental protection, zero pollution, safety and low cost of use, and have gradually become the main form of boat power. According to the data disclosed by GGII, the penetration rate of lithium battery in boats in 2019 is 0.04%, and the penetration rate in 2022 and 2025 is expected to reach 0.55% and 18.5%. With the continuous increase of the penetration rate of lithium batteries in China’s boats, its market size will also continue to rise.
The future application prospect of power lithium battery boats is relatively broad
According to the disclosure of Lithium Battery, the current electric marine lithium battery uses lithium iron phosphate power battery, and the future trend of marine lithium battery will mainly focus on the following areas:
- Ferry boats and sightseeing boats in coastal cities along the river;
- Inland river cargo boats;
- Port tugboat market;
- Some large and medium-sized boats use lithium batteries instead of lead-acid, thereby accelerating the use of lithium batteries in boats.
