Vasileios Kosmas is a Senior Researcher at the Hapag-Lloyd Center for Shipping and Global Logistics (CSGL) of Kühne Logistics University. His work focuses mainly on environmental policies, green technologies, and alternative fuels within the maritime transport industry. Particularly, he is the lead researcher of the “Policy and viable business” work package of the Wind Assisted Ship Propulsion (WASP) project which is partially funded by the European Regional Development Fund. Among others, he is responsible for enhancing the viability of WASP business cases, investigating innovative business models and exploring the economic implications of such technologies on the shipping industry. Furthermore, Dr. Kosmas was one of the lead investigators of the “Feasibility study and support for missing data for maritime sector technical specifications”; the study was in cooperation with the Joint Research Center of the European Commission and dealt with the uptake of alternative fuels in the EU maritime sector. In addition to the above areas, his work deals with the examination of social issues in supply chains, particularly with search and rescue operations within the context of migration by sea.
Dr. Kosmas holds a Ph.D. diploma in Operations Management from Copenhagen Business School. Additionally, he holds a MSc degree in Maritime Transport with Management from Newcastle University. The degree and thesis, which focused on inland waterways transportation in Europe, were conferred with distinction. Dr. Kosmas holds a BSc degree in Economics from Aristotle University of Thessaloniki. He also gained industry experience during his internship at the Development Company of Thessaloniki’s Chamber of Tradesmen. Last but not least, Dr. Kosmas is a member of the International Association of Maritime Economists and acts also as a reviewer for international scientific journals.

Abstract: Wind-assisted ship propulsion (WASP) technology seems to be a promising solution toward accelerating the shipping industry’s decarbonization efforts as it uses wind to replace part of the propulsive power generated from fossil fuels. This article discusses the status quo of the WASP technological growth within the maritime transport sector by means of a secondary data review analysis, presents the potential fuel-saving implications, and identifies key factors that shape the operational efficiency of the technology. The analysis reveals three key considerations. Firstly, despite the existing limited number of WASP installations, there is a promising trend of diffusion of the technology within the industry. Secondly, companies can achieve fuel savings, which vary depending on the technology installed. Thirdly, these bunker savings are influenced by environmental, on-board, and commercial factors, which presents both opportunities and challenges to decision makers.

Abstract: The maritime sector is a key asset for the world economy, but its environmental impact represents a major concern. The sector is primarily supplied with Heavy Fuel Oil, which results in high pollutant emissions. The sector has set targets for deacrbonisation, and alternative fuels have been identified as a short-to medium-term option. The paper addresses the complexity related to the activities of the maritime industry, and discusses the possible contribution of alternative fuels. A sector segmentation is proposed to define the consumption of each sub-segment, so to compare it with the current alternative fuel availability at European level. The paper shows that costs and GHG savings are fundamental enablers for the uptake of alternative fuels, but other aspects are also crucial: technical maturity, safety regulation, expertise needed, etc. The demand for alternative fuels has to be supported by an existing, reliable infrastructure, and this is not yet the case for many solutions (i.e. electricity, hydrogen or methanol). Various options are already available for maritime sector, but the future mix of fuels used will depend on technology improvements, availability, costs and the real potential for GHG emissions reduction.

Abstract: A fuel levy is one of the market-based measures (MBMs) currently under consideration at the International Maritime Organization. MBMs have been proposed to improve the energy efficiency of the shipping sector and reduce its emissions. This paper analyses the economic and environmental implications of two types of levy on shipping bunker fuels by means of an analytical model built on the cobweb theorem. A unit-tax per ton of fuel and an ad-valorem tax, enforced as a percentage of fuel prices, are examined. In both cases, a speed and fuel-consumption reduction equivalent to an improvement in the energy efficiency of the sector would be expected as a result of the regulation enforcement. The speed reduction in the unit-tax case depends on fuel prices and the tax amount, whereas in the ad-valorem case it relies upon the enforced tax percentage. Both schemes lead to industry profit decline, the extent of which depend on the structure of the levy and market conditions. Since there is concern that the costs resulting from the policy will be passed from shipping companies to their customers along the supply chain, the paper dwells on how the costs arising from the enforcement of the levy will be actually allocated between ship-owners and operators, and cargo-owners. In a market characterised by high freight rates and with no or limited excess capacity, a higher percentage of the total tax amount is transferred from ship-owners to shippers. In case of a recession the opposite happens.
