Exploring new pathways to emission reduction

摘要

With the objective of achieving drastic reductions in emissions, while ensuring a simultaneous advance in efficiency, a solution based on an innovative blend of technologies is being investigated by industry and academia in the HyMethShip project. The consortium of 13 partners from six countries is working on a hydrogen/ methanol-based propulsion system designed to cut CO_2 by at least 97%, take NOx to 80% below the IMO Tier Ⅲ limit, and virtually eliminate SOx and particulate matter (PM). The concurrent goal is a 45% gain in efficiency relative to the best available technology. The envisaged, integrated shipboard installation combines a membrane reactor, a CO_2 capture system, CO_2 and methanol storage tanks, and hydrogen-capable reciprocating engine. The modus operandi is that methanol supplied to the vessel is reformed to hydrogen, which is then burned in an engine adapted for multi-fuel operation with optimisation to hydrogen.
