Abstract

Although domestic ferries play an important role in the economy and security of the Philippines, they have serious negative environmental impacts on cities and society due to the use of fossil fuels. There is a great potential to use battery and hybrid vessels in the segment. However, the necessary infrastructure, such as cold ironing technology in ports, is not available and the source of the national grid (coal) is more polluting than the ships' fuel (diesel oil). It is therefore important to replace the existing energy sources with renewable energy. In this study, the potential use of solar and wind power and generators in six different stand-alone and grid-connected systems for a major port in the Philippines was assessed in 1423 simulations using a smart grid optimization software and a Python program. Grid-connected systems were more cost-effective and environmentally friendly than stand-alone mode systems, and wind power systems with a Levelized Cost of Electricity (LCOE) of 0.081 ($/kWh) were the most cost-effective system. The sensitivity analyses showed that switching from diesel generators to gas generators led to a 67.63-75.2% reduction in the related LCOE and a 78% and 73% reduction in the operating cost and total net present cost of the stand-alone systems, respectively.
