The Carbon Intensity Indicator (CII) is one of the short-term measures introduced by the International Maritime Organization (IMO) to reduce greenhouse gas emissions from shipping. This policy brief reviews the measure and provides improvement recommendations, f

"Abstract Hydrogen is stored at high pressure making discharge a safety concern, including flame stability issue. Previous studies were focused on circular nozzles. However, actual incidents are more likely to involve slit-shaped openings. The experimen

"Abstract Yard equipment upgrades are vital for port decarbonization, yet the coexistence of legacy and new yard cranes creates challenges in coordinating operations and allocating limited electrical power. This paper studies the integrated cont

Maritime policy bulletin 007 covers CO2 emission reduction technologies for shipping. In recent years maritime shipping has emitted approx. one gigatonne of carbon dioxide (CO2) per annum. Based on current trends this is projected to increase 150-250% by 2050

"Abstract Innovative marine propulsion systems play a pivotal role for decarbonising global maritime transportation. This study investigated an ammonia-fuelled hybrid powertrain system that integrates ammonia internal combustion engines with a battery e

"Abstract Freight transport contributes 8 % of GHG emissions and requires propulsion systems that deliver both sustainability and high efficiency. This study introduces a novel system-level approach that links experimental data to modelling of a recupe

The UK National Clean Maritime Research Hub launched its first quarterly newsletter on 14 November 2025. This inaugural edition provides an overview of key developments and updates from the UK National Clean Maritime Research Hub, including details of upcomi

"Abstract The maritime shipping sector is a significant contributor to global carbon dioxide (CO2) emissions, accounting for approximately 2.7%-3% of global emissions. In response, the International Maritime Organization (IMO) has set ambitious targets:

"Abstract Ammonia, a promising carbon-free fuel, offers practical advantages over hydrogen, such as liquid-phase storage, making it suitable for direct use in compression ignition engines. As a hydrogen carrier, ammonia has the potential to deca

"Abstract Microalgae oil (MAO), a third-generation biofuel, can support global transportation fuel demand as a fossil fuel substitute. Schizochytrium sp. MAO is particularly promising for direct use in compression ignition (CI) engines, especially in
