Methanol has been identified as a very good alternative to replace oil based fuels in the maritime sector. This view is corroborated by the results of the Swedish Energy Agency's analysis of one molecule fuels. More stringent environmental requirements have accelerated the development of alternative maritime fuels and today there exist large marine methanol engines. However, there are no methanol alternative in the smaller engine segment (250-1200 kW). In SUMMETH these engines will be developed with focus on energy and cost efficiency. Recommendations are given for the introduction of methanol in coastal and inland waterway shipping with the aim to reduce emissions and carbon footprint. SUMMETH will explore the possibilities for the existing maritime market to adapt to methanol use, test and evaluate various methanol combustion techniques and provide recommendations for on-board system and adaptations required for the installation of these systems. Distribution and availability of renewable methanol for shipping will also be evaluated.
