The shipping industry's biggest players are shrugging off Trump administration opposition to a global carbon price and are forging ahead with billions of dollars in emissions-reducing investments, according to company officials and a Reuters analysis of data.Europe, Brazil and a host of other nations are pushing the sector, which is responsible for nearly 3% of the world's greenhouse gas emissions, to go green. But, in October, the U.S. and Saudi Arabia, the world's two largest oil producers…

Commissioned and published by the European Maritime Safety Agency (EMSA), a new report focused on the safety of ammonia as a marine fuel was developed by an ABS-led consortium that included the National Technical University of Athens (NTUA) and the Fundación Valenciaport.Based on the insights gained from the study, the report includes recommendations that expand upon existing interim guidelines from the International Maritime Organization for the safety of ships using ammonia as fuel.

While the IMO has established interim guidelines to facilitate the use of ammonia as a marine fuel, international standards governing the safe treatment and discharge of toxic ammonia effluent generated during vessel operations have yet to be developed.Unlike typical aqueous ammonia, this effluent exhibits different physical and chemical characteristics, and the lack of clearly applicable international standards has created uncertainty for ship design, operation, and environmental management.In response…

Is LNG to ammonia a viable pathway for helping shipowners get to net zero?From an engine point of view there is a pathway, but there are two points to consider, says Lars Tingbjerg Danielsen, Two-Stroke Promotion Manager – Newbuildings at Everllence. First, the case where an engine is capable of burning both methane and ammonia; second the case where an engine starts its service burning methane and then later switches to burning ammonia.“If we look at the idea of an engine capable of burning both methane and ammonia, it is our belief that this is not a request from the market.

Everllence has unveiled its new, dual-fuel ME-LGIA (-Liquid Gas Injection Ammonia) engine.Using the Diesel principle and the well-known, dual-fuel liquid gas injection concept, the ME-LGIA engine has many of the same features as Everllence’s existing ME-LGIM and ME-LGIP units that, respectively, run on methanol and LPG.However, in light of ammonia’s particular characteristics, the new engine also has additional safety features such as containment systems, sensors, system ventilation…
