At last month’s International Tug & Salvage Conference, Corvus Energy Ltd presented a paper on a new battery type – Nickel Manganese Cobalt , NMC for short, that is particularly good for propulsion applications. It uses safe chemistry that is stable and reliable. is sealed and is compact. It can deliver a high power until fully discharge, doesn't’t deteriorate if left uncharged and hardly looses its charge over time. What does this mean for the marine industry? One example was the announcement at the Conference of an all electric tug boat, so far it is only for training purposes but heralds the beginning of a new era of electric driven vessels whether pure electric drive or hybrid diesel electric.

Lloyd’s Register’s recently announced a research program into nuclear propulsion of ships. After the 1960’s Savannah and Otto Hahn there were only two more commercial ships produced with nuclear propulsion: there were also nuclear ice breakers built by the Soviet Union. Opposition to nuclear power in the light of the problem of greenhouse gases is changing opinions. Nuclear propulsion technology has continued to develop but the high initial cost has to be paid up front. Radioactive waste is an unresolved problem, yet there are few problems man is unable to solve when the necessity is strong. The greatest nuclear benefit is in zero exhaust emissions.

The high cost and complexity of modern ships may point to an alternative to the sale or scrapping a vessel as it ceases to fulfill all the requirements of its original task. In some cases new or upgrading older engines, in other cases the propulsion configuration is changed, rewarding the operator with lower fuel costs and emissions.
