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. First, it contains very little sulfur.

EU research project IDEALFUEL seeks to develop marine low-sulfur heavy fuel oils from biomass; Bio-HFO

Green Car Congress

In an EU-funded research project, an international consortium is aiming to develop new production methods for sustainable marine fuels to replace heavy fuel oils in shipping. However, HFOs are banned in the national waters of many countries. Although cleaner fuels are available, many companies opt for HFOs due to their low cost.

MAN reports successful first running of ammonia two-stroke engine

Green Car Congress

This marks a major milestone on our road to developing a full-scale two-stroke ammonia marine engine. This successful combustion represents yet another, important step towards decarbonizing the marine market and bringing big things to zero. Similarly, all auxiliary systems were initially tested with water, followed by ammonia.

IDTechEx: future of the electric ship industry lies with hybrid cargo vessels

Green Car Congress

More than 1GWh of batteries are now sailing on waters globally, reflecting 72% industry growth in 2022, according to a new report from IDTechEx. First, electric ship markets have historically been underpinned by electric ferry orders, which made up 37% of the maritime battery capacity (GWh) deliveries between 2019 and 2022.
