A brief description of NOX emission requirement

Regulations


In this article, a brief explanation on the limiting requirements for NOx emissions from marine diesel engines is given and the three emission tiers are briefly reviewed.

Ammonia as a marine fuel

Machinery


Ammonia has attracted wide interest as a source of zero emission fuel for shipping. Ammonia has the key benefit of being easier to store than hydrogen, i.e. nearly identical to propane (LPG) at low pressure under ambient conditions. Hence, the cost of storage per energy unit is significantly cheaper than either hydrogen, electricity in batteries or LNG.

The Engine International Air Pollution Prevention Certificate (EIAPP Certificate)

Regulations


The Engine International Air Pollution Prevention Certificate (EIAPP Certificate) plays a pivotal role in addressing Nitrogen Oxide (NOx) emissions from marine engines. This certification, governed by the NOx Technical Code, employs prescribed test cycles and measurement methods to calculate NOx emissions, emphasizing compliance with stringent environmental standards.

MOL receives new dual-fuel methanol vessel in South Korea

Technology


Mitsui OSK Lines (MOL) has taken delivery of a new dual-fuel methanol carrier at Hyundai Mipo Dockyard in South Korea. Named Cypress Sun, the vessel has been designed to operate using both methanol and traditional heavy fuel.
