Low Carbon Shipping & Shipping in Changing Climates

A Research Led Consortium on Sustainable Shipping

 
 

SCC Conference 2017 papers now available

Papers from the successful fourth SCC international conference in association with IMarEST held at UCL on the 4th & 5th September are now available. The conference brought together academics and industry to find ways to help shipping transition towards a low carbon future. Topics included data analysis and energy efficiency, low carbon design and technologies, modelling, alternative fuels, economics and policy of low carbon shipping. Full list of papers and presentations can be found in the publications section.

Presentation at the Third IMO GHG Intersessional working group - The costs of GHG reduction in international shipping (IMarEST ISWG-GHG 3-3)

Dr Tristan Smith and Katharine Palmer presented the findings from the submission ISWG-GHG 3-3. The key findings include:
- Improving energy efficiency for a given size and type of ship is ultimately limited by the laws of physics. Thus, energy efficiency measures on their own are not enough.
- The price of zero-emission fuels would dominate the cost of decarbonization of international shipping. Table 1 shows various initiatives undertaken by the private sector, including shipowners and operators.
- Depending on how prices evolve for renewable electricity in coming decades, 100% absolute reduction of shipping GHG by 2050 appears achievable for a marginal abatement cost of $100 to 500 US$/t.
- Whilst hydrogen is well known as a potential future marine fuel, ammonia is less known and an interesting result was that for certain ship types, ammonia appears to outperform hydrogen in terms of profitability (figure 2).
- Conclusion: After initial increases in abatement cost, the cost curve reaches a "plateau" at a value which represents the carbon price needed to make zero-emissions technologies competitive with conventional propulsion.

UCL Energy Institute RBSA study sheds light on the Energy Efficiency Operational Indicator and the challenges for policymakers in implementing MRV

UCL on behalf of the Royal Belgian Shipowners Association (RBSA) looked into the drivers of the indicator by carrying out a series of analyses on a set of owner-reported data, similar to the data that will be used to comply with the future legislation at IMO and EU MRV. As well as calculating the carbon emissions and values of Energy Efficiency Operational Indicator (EEOI) for ships in the RBSA’s owner’s fleets, the study decomposed the EEOI into sub-indices (technical and logistics factors) and in terms of the contribution of the laden, ballast and port segments to EEOI for 94 ships in the bulk carrier, chemical tanker, container, liquefied petroleum gas and oil tanker sectors over the period 2008-2014. This period saw a variation in market factors such as fuel prices and freight rates, which have influenced the way in which the ships were operated and has undoubtedly cascaded into changes in the EEOI over time.

Increased Capacity at Terminals and Reduction in Carbon Footprint Possible Through EcoHubs ICT Tools

  • 20% increase in terminal capacity
  • 50% reduction in carbon footprint

The EU funded EcoHubs R&D project (Environmentally COherent measures and interventions to debottleneck HUBS of the multimodal network favoured by seamless flow of goods) has successfully delivered a number of proven ICT tools which can increase capacity at ports and terminals, and can lead to significant reductions in carbon footprint.

Designed to support “Resource Efficient Europe”, the flagship initiative of the Europe 2020 Strategy, EcoHubs has, for the last 30 months, researched and developed the tools required for sustainable freight transport and logistics networks as part of a smart, safe, environmentally friendly and inclusive EU economy.

Adria Kombi, a leading combined transport operator in Slovenia is deploying the CCIS (Container Interfacing and Consolidation System) tool in conjunction with the ecoTAURuS (Ecohubs Truck Appointment & Unit Reporting Status Services) system at the Port of Koper and estimates that when fully implemented, this will lead to a 20% increase in capacity. This increase requires no additional physical infrastructure investment and an improvement of throughput by 15%, equating to a 1.6 – 2.3 Million Euros in turnover can be realised.

As part of its efforts to provide a complete CO2 footprint measuring system which can calculate and declare the energy consumption and GHG emissions of transport services, EcoHubs also developed the ITEC (Intermodal Terminal Eco-Efficiency Calculator) tool.

Technologies for the high seas: meeting the climate challenge

Tyndall Manchester have published new research in the Journal of Carbon Management on technologies and engineering capability to deliver CO2 emission cuts in the shipping sector.

The research looks explicitly beyond incremental change, and uses a participative technology roadmapping process to explore opportunities for and barriers against ‘radical’ (urgent and deep) CO2 mitigation in the shipping sector. Promising technologies for delivering short-term cuts including wind-propulsion, small-scale fuel cells and some penetration of biofuels, benefiting from slow-steaming as a pre-requisite.

Through technology and engineering the outlook for the sector to significantly cut its CO2 emissions is promising. Full article

Shipping charts a high carbon course

A new commentary by Alice Bows-Larkin and Tyndall Manchester colleagues, published in Nature Climate Change discusses how the shipping industry expects ongoing growth in CO2 emissions to 2050, despite an apparent recent decline and that opportunities for decarbonizing the sector in line with international commitments on climate change need to be re-evaluated.
