WP2 Present and Future Maritime Fuels

The purpose of the WP is to identify present and possible future fuels for maritime use.

Oil has for the last 50 years been the dominating fuel for ship propulsion. Changing conditions and concerns such as price, availability, emissions, operating conditions and legislation have made the oil less attractive and there is a growing interest to find alternatives which will be available in the long term perspective.

The team will compile an overview report with focus on a wide picture of maritime fuel in short term, medium term and long term perspectives. Clean land based local power generating systems will serve as an important reference.

The most promising fuels will be identified. For these alternatives the WP2 will investigate availability, price, emissions, other environmental impact from a life cycle perspective, operation characteristics in the engines, storage, bunkering, handling, space requirements in the ship, safety, and class approval. A successful implementation of an alternative maritime fuel requires a reliable and adequate supply and that it can be offered in many (or “enough”) ports. Otherwise it might result in increased environmental impact and higher costs for the shipping companies.

This work package will also analyse how the logistic system can be designed to support the supply of new fuels and what is necessary to create opportunities for a successful implementation into the market. A risk analysis will be carried out for the supply of the various fuels considered, and will include an assessment of risk of transport to the port, storage at the port and onboard the vessel, and bunkering activities.

The WP2 findings will serve as an important input to WP3 and WP4. The various fuel alternatives will have different problems related to exhaust gas cleaning,e.g. exhaust gas after-treatment technologies such as scrubbers, require a supply of input materials (consumables) and handling of waste products in port. The different fuel alternatives also have different possibilities regarding exhaust gas energy recovery.
