Today, around 90 per cent of the world’s trade in goods, is carried by sea. According to Shipping Intelligence Weekly, there were approximately 58,000 cargo carrying ships operating in June 2012. It has been calculated that maritime shipping is responsible for emitting over 1 billion tons of carbon dioxide (CO2) per year accounting for over 3% of worldwide CO2 emissions in 2007. The world oil tanker fleet was responsible for some 12 per cent of total CO2 emissions by global shipping, reported the International Maritime Organisation (IMO) in 2012.

Currently, the global maritime industry’s ships and tankers rely on engines fuelled by heavy bunker oil and diesel. However, a combination of rising oil prices and ever stricter environmental regulations have raised operating costs driving ship owners to demand greater fuel efficiency, lower emissions and faster turn-around times in port. Nicholas Newman looks at how ship operators are seeking new ways to cut costs and reduce pollution by the adoption of new methods of powering ships including sail, LNG, solar, hydrogen, batteries…
