There has been a recent upsurge in the demand of renewable sources over outdated fossil fuel technologies and these are not only limited to power production but has also shown a great increase in the use of battery powered vehicles. Same trend is followed for marine transport industry and many research project are already in place to meet these demands of future. One such solution to complex application of marine transport is to use Hybrid Energy Storage System (HESS). It’s a system that includes both power and energy dense batteries namely High Power (HP) and High Energy (HE) respectively. With HESS system we can better utilize the batteries to their fullest extend and along the way we can reduce the cost and increase the efficiency as well.
