On the sustainability of CO₂ storage through CO₂ – Enhanced oil recovery

This work uses pilot examples of CO₂ enhanced oil recovery to analyze whether and under which circumstances it is exergetically favorable to sequester CO₂ through enhanced oil recovery. We find that the net storage efficiency (ratio between the stored and captured CO₂) of the carbon capture and storage (CCS)...

Design Framework for a Modular Floating Container Terminal

The design and development of an offshore port terminal is a complex task that involves distinctive design and decision challenges. In this paper, we propose the implementation of a floating, modular, platform that can act as an additional terminal of a port, with the aim of expanding its current container handling capacity. To this end, we...

Waterborne Hinterland Transports for Floating Port Terminals

Port terminals on floating modular platforms are a conceivable solution for the problem of limited space and water depths restrictions of ports in estuary regions. A design of a dedicated Transport&Logistic hub has been developed in the scope of the Horizon 2020 project Space@Sea. This paper addresses dedicated options of waterborne...

Green Bulk Terminals: a Strategic Level Approach to Solid Biomass Terminal Design

This thesis deals with the design of solid biomass terminals from a strategic operational point of view. The design of terminals is here characterized as the total equipment selection, purchase, utilization and salvage within the terminal bounds.

Optimal equipment deployment for biomass terminal operations

This paper investigates the optimization of biomass terminal equipment deployment. A mixed integer linear programming model is developed and applied to minimize the terminal's investment and operational costs related to dedicated and partially used or shared equipment between a terminal's operational steps. The results minimize annual...

Evaluation of wood pellet handling in import terminals

Wood pellet imports are expected to increase in the European Union and Southeast Asia by 2030, considering pellets are the main feedstock used for co-firing in power plants throughout these regions. Due to the material's physical and biological properties, the equipment at an import terminal need to be different than what is used for other...

Review of solid and liquid biofuel demand and supply in Northwest Europe towards 2030: A comparison of national and regional projections

Biomass is the largest source of renewable energy carrier in the European Union (EU) contributing to over 60% of renewable energy, with the majority of supply coming from domestic sources. However, an increasing significant amount of feedstock is imported, either due to domestic undersupply or higher production costs within the country. This...

Assessing the representativeness of durability tests for wood pellets by DEM Simulation: Comparing conditions in a durability test with transfer chutes

Dust generation when handling wood pellets is related to the durability of the product, in other words the wear rate of particles subject to forces. During transport, storage and handling wood pellets undergo different forces when interacting with different pieces of equipment.<br/><br/>This paper assesses the representativeness of the tumbling...
