ABS grants Alfa Laval the marine industry’s first approval in principle (AIP) for firing boilers with methanol

Green Car Congress

Maritime classification society the American Bureau of Shipping (ABS) has granted Alfa Laval the first marine approval for operating boilers on methanol. Marine boilers generate steam for auxiliary machinery for various ship services or, in some cases, for main propulsion. Source: Alfa Laval.

ICCT life-cycle analysis finds no climate benefit in using LNG as marine fuel

Green Car Congress

The results of a new analysis by the International Council on Clean Transportation (ICCT) show that, when combined with a trend toward higher methane leakage and combustion slip, there is no climate benefit from using liquefied natural gas (LNG) as a marine fuel—regardless of the engine technology. Olmer et al.

HyMethShip seeks to fuel ship engines with hydrogen from methanol

Green Car Congress

The EU-funded HyMethShip project developed a system that innovatively combined a membrane reactor, a CO 2 capture system, a storage system for CO 2 and methanol as well as a hydrogen-fueled combustion engine to power ships. The bottom part shows how hydrogen for the engine is obtained from methanol in the reactor (blue arrow).

Rolls-Royce and Robert Allan present world’s first LNG-powered shallow-water push boat

Green Car Congress

Rolls-Royce and Canadian vessel designers Robert Allan have developed the world’s first shallow-water push boat powered by LNG natural gas engines. LNG engines produce no particulate whatsoever, emitting significantly less NO x than diesel engines. In addition, gas, where available, offers lower running costs.

Alfa Laval introduces E-PowerPack ORC waste heat recovery system for ships

Green Car Congress

—Lars Skytte Jørgensen, Vice President Technology Development, Energy Systems, Alfa Laval Marine Division. These include exhaust gas waste heat, which accounts for 50% of the energy from combusted fuel, but also liquid sources at lower temperatures, such as engine jacket water. All can make a sizeable difference.

Harvey Gulf orders Wärtsilä 746 kWh battery systems for another four LNG-powered supply vessels

Green Car Congress

The boats will be capable of closed bus Dynamic Positioning (DP) operation running only one engine augmented by the Wärtsilä Energy Storage System. When stationary in the field or in port, the boats will be able to operate on battery power only, thereby greatly reducing both fuel consumption and exhaust emissions.
