Prioritising green technologies
It will be difficult to assess the available solutions for compliance with the 0.50% m/m IMO sulphur limit
The inconvenient truth
When considering the adoption of green technologies some took a near term perspective, preferring that priority is given to proven solutions such as LNG or solving the challenges posed by imminent regulatory change, in particular, IMO’s global cap on sulphur content in ship fuel. Others considered a medium term horizon, with particular emphasis on pushing the development of energy storage (batteries and fuel cells) and hybrid power arrangements. The transfer of harmful aquatic organisms into new ecosystems by ships’ ballast water or hull biofouling was raised only as a secondary consideration. This is perhaps explainable by the fact that a regulatory framework is already in place and technical solutions are forthcoming.
In certain circumstances, solutions aimed at mitigating one type of pollution may cause other problems. For example, improving the combustion efficiency of ship engines to reduce carbon dioxide can result in increased NOx emissions. Therefore, it is important to take a holistic view of a particular solution’s overall impact. Attention is especially needed when any additional plant affects a vessel’s total energy requirements, such as the extra electrical load needed to run ballast water treatment systems or the use of scrubbers to clean exhaust gases. In addition, storing consumables onboard may reduce cargo or passenger carrying capacity, which affects both operational and commercial efficiency.
