The transition to battery-electric propulsion

Despite potential benefits, the adoption of battery-electric propulsion in deep-sea shipping faces several challenges. These include the limited energy storage capacity of current battery technology, the need for significant infrastructure investments, and the potential impact on cargo capacity.

The study focused on identifying the technical and economic barriers to battery-electric propulsion, assessing its viability in different vessel segments, and comparing its environmental impact to traditional fuel sources.

Key Findings

• Hybrid Power Plants: A hybrid approach combining battery-electric components with internal combustion engines offers a promising solution to overcome the limitations of pure battery-electric propulsion.
• Economic Viability: Battery-powered container ships using a hybrid power plant approach can be economically competitive with traditional vessels.
• Environmental Benefits: Battery-electric propulsion can significantly reduce greenhouse gas emissions compared to traditional fuels, especially when combined with renewable energy sources.

The Path Forward

To realise the full potential of battery-electric propulsion in the maritime sector, several factors need to be addressed. These include:

• Infrastructure Development: Investment in shore power and charging infrastructure is crucial to support battery-powered vessels.
• Battery Technology Advancements: Continued research and development are essential to improve battery energy density and reduce costs.
• Regulatory Support: Clear policies and regulations are needed to incentivize the adoption of battery-electric propulsion.

By addressing these challenges and capitalising on the opportunities presented by battery-electric propulsion, the maritime industry can play a vital role in achieving a more sustainable and decarbonised future.
