Actually, commercial shipping is the most effective sector. Wartsila diesels have BSFC of 0.260 bs hp/hour. I wonder how it compares to GEx?
It would be a lot easier to accept that industry's green credentials if they ceased their practice of dumping palm oil on the Norfolk and Suffolk coasts. No friction-reducing gains to be made by keeping that on board, of course.
