Methanol exhibits a high auto-ignition threshold of 470 degrees Celsius compared to conventional marine diesel, which ignites spontaneously at just 210 degrees Celsius under pressure. To overcome this chemical limitation, modern vessels utilize advanced dual-fuel engines that deploy a precise pilot injection strategy, firing a small fraction of diesel to ignite the primary methanol charge.
Furthermore, methanol possesses an energy density of roughly 19.7 megajoules per kilogram, which is less than half the energy content found in standard diesel. This severe deficit means cargo vessels must carry more than twice the volume of fuel, requiring larger onboard stainless-steel tanks or more frequent refueling cycles.
