The maritime industry has worked with a single fuel source for over a century and with the rush to meet emission standards in both domestic and foreign markets, adapting to the current list of alternative fuels is going to present significant problems. Each market has its issues whether bluewater, brownwater, coastal, foreign or domestic.
Chose any of the larger global shipbuilding yards and the basic bluewater ship design will include a large two stroke combustion engine.
To remove that single propulsion system from current ship construction to meet emission standards would be devasting to shipyard profitability.
First, we need to realize the current emission time frame will not be met and second ship orders will continue to include this type of propulsion well into the near future.
The climate change and ship emission discussion reach as far back as 2012, with an analysis of ammonia as a military fuel. Doctor William Ahlgren defined the transition away from fossil fuels as a “Dual Fuel Strategy”. The analysis coupled fossil fuel energy sources with electric power and the research presented three strategies for an alternative energy future:
- a hydrogen economy coupling electric power and hydrogen fuel,
- a complete electric economy, and
- a dual fuel strategy
