Grid connected Voltage Source Converters (VSCs) with LCL filters usually have voltage measurements at the filter capacitors, while it can be important to control the active or reactive power injection at the grid-side of the LCL filter, for instance at a Point of Common Coupling (PCC...

The objective of the CruiZE project is to develop innovative, integrated and environment-friendly concepts for supplying heating and cooling needs for the hotel facilities on board cruise ships. As in other sectors, there are non-technological barriers which must be addressed to pave the way...

The H2020 project FlexPlan considers the development and validation of an innovative grid planning tool. In this paper, we present the methodology used in the simulation toolchain and preliminary results for optimal power flow simulation performed in four different regional cases covering most parts...

For decades, the refrigeration technology research groups at NTNU and SINTEF have been developing components, cycles and methodologies to promote attractive solutions using natural working fluids. The same values and vision were brought along when the same research groups branched out into...

Carbon capture and storage (CCS) activities need to be ramped up to address the climate crisis. Abatement cost curves can help to identify low-cost starting points and formulate roadmaps for the implementation of CCS at industrial sites. In this work, we introduce the concept of energy supply cost...

Power- and biomass-to-liquid fuel processes (PBtL) can utilize renewable energy and residual forestry waste to produce liquid synthetic fuels, which have the potential to mitigate the climate impacts of the current transportation infrastructure, including the long-haul aviation sector. In a previous...

Fluids confined in small volumes behave differently than fluids in bulk systems. For bulk systems, a compact summary of the system's thermodynamic properties is provided by equations of state. However, there is currently a lack of successful methods to predict the thermodynamic properties of...

The field data from an integrated CO₂ refrigeration system installed in a supermarket located north of the capital of Lisbon was analyzed. The goal was to demonstrate the effect and performance of multi-ejectors on a refrigeration system operating in a warm climate. The measurement results for the...
