The recent targets by different countries to stop the sales or registrations of internal combustion engines (ICE) have led to the further development of battery and fuel cell technologies to provide power for different applications. The main aim of this study is to evaluate the possibility of using an integrated Lithium-Ion battery and proton exchange membrane fuel cell (PEMFC) as the prime mover for a case study of a 800 kW ferry with a total length of 50.8 m Read More

Many small Canadian communities lack access to electricity grids relying instead on costly and polluting diesel generators despite the local availability of renewable energies like solar and wind. The intermittent nature of these sources limits reliable power supply; thus hydrogen is proposed as a cost-effective and ecofriendly long-term energy storage solution. However it remains uncertain whether hydrogen storage can significantly contribute to a 100% Read More
