Shipowners need to prepare for low-emission fuel alternatives to meet the IMO 2050 goals. This is a complex problem due to conflicting objectives and a high degree of uncertainty. To help navigate this problem, this paper investigates how methods that take uncertainty into account, like robust optimization and stochastic optimization, could be...

Hydrogen carriers are attractive alternative fuels for the shipping sectors. They are zero-emission, have high energy densities, and are safe, available, and easy to handle. Sodium borohydride, potassium borohydride, dibenzyltoluene, n-ethylcarbazole, and ammoniaborane are interesting hydrogen carriers, with high theoretical energy densities....

Climate change due to greenhouse gas emissions is prompting the IMO to reduce emissions by 80% by 2050. This thesis focuses on designing modular propulsion systems for mid-speed sailing vessels to meet these regulations. It designs a framework to generate and swiftly evaluate propulsion system designs on the basis of five performance indicators:...

Alternative fuels can help the maritime shipping industry to lower its emissions. However, there are commercial risks that surround the adoption of these cleaner fuels. A book & claim based carbon insetting initiative could reduce these commercial risks and accelerate the decarbonization of the maritime shipping industry. Carbon insetting is...

International and local legislation on emission reduction urge the Dutch beam trawler fleet to reduce the use of fossil fuels. In 2015 the United Nations Paris Agreement was signed and as a result IMO and EU set the objective to reduce the GHG or CO2 emissions of the shipping industry. The Dutch beam trawler<br/>has been confronted with many...

The maritime sector is actively investigating new solutions for zero emissions in<br/>response to climate change. One of the promising options is hydrogen-based propulsion, but there are currently no prescriptive rules or legislation to approve the design of such innovative, unproven technology. The International Maritime Organization (IMO)...

Many fuels are currently considered for reducing the emissions in shipping; Methanol, LNG, Ammonia, Nuclear, Biodiesel, etc. However, Bio-ethanol is not considered at all.This research looked into all aspects of ethanol in a comparison with its most closely related alternative methanol. Using a similar approach as found in earlier comparisons....

This paper investigates the spatial requirements of alternative marine energy carriers and their impact on ship design and powering for constant operational requirements. A parametric design tool for bulk carriers, tankers, and container ships has been developed for the predicted future marine energy carriers to determine the main engine brake...

This thesis investigates the total environmental impact of various alternative marine energy carriers while taking the powering increase into account due to their disadvantageous spatial requirements compared to conventional fuel. A parametric design tool for bulk carriers, tankers, container ships, and trailing suction hopper dredgers has been...

It is essential to use alternative fuels if we are to reach the emission reduction targets set by the IMO. Hydrogen carriers are classified as zero-emission, while having a higher energy density (including packing factor) than pure hydrogen. They are often considered as safe alternative fuels. The exact definition of what safety entails is often...

Green hydrogen combined with PEM fuel cell systems is a viable option to meet the demand for alternative maritime fuels. However, hydrogen storage faces challenges, including low volumetric density, fire and explosion risks and transport challenges. We assessed over fifteen hydrogen carriers based on their maritime performance characteristics...

This paper explores the design and feasibility of a 200-passenger, 30- to 40-knot emission-free ferry as a potential variant of the traditionally powered Coastal Cruiser 200 ferry currently operating in the Chinese Pearl River Delta. The Pearl River Delta is one of China’s most densely urbanized regions and faces numerous social, health, and...

An increasing demand in the marine industry to reduce emissions led to investigations into more efficient power conversion using fuels with sustainable production pathways. Solid Oxide Fuel Cells (SOFCs) are under consideration for long-range shipping, because of its high efficiency, low pollutant emissions, and fuel flexibility. SOFC systems...

This article examines the potential implications of using iron powder as an alternative fuel on the design and performance of container ships. Iron powder is a relatively new alternative energy carrier and one in which little research has been done into the application on-board vessels as part of the maritime energy transition. The key...

PIANC provides guidance and technical advice for sustainable waterborne transport infrastructure. To address the challenge of making inland navigation infrastructure sustainable, a Task Group “Infrastructure for the decarbonisation of Inland Water Transport” (TG234) was set up in January2021. The objective of the TG was to identify knowledge...

The offshore wind market is growing rapidly, and new offshore wind projects are being launched more than ever. To keep up with demand, parts for these wind turbines are being produced all over the world. To get all the parts needed to their destination on time, they must be transported on heavy transport vessels (HTVs).<br/><br/>Today, business...

The current global fleet is still dependent on conventional fuels as energy source to transport goods to various places in the world. These conventional fuels, such as MGO or HFO, emit large amounts of greenhouse gasses and other pollutant emissions. Regulation concerning these emissions becomes stricter every day, therefore institutions and...
