The objective of this study is to evaluate the energetic, exergetic, sustainability, economic and environmental performances of a 4-cylinder turbodiesel aviation engine (TdAE) used on unmanned aerial vehicles for the take-off operation mode to assess the system with large aspects. Energy efficiency of …

The emission of greenhouse gasses is a trending subject worldwide. Also the maritime industry is looking for alternative options for zero-emission transport. Nedstack provides fuel cells as a solution for this challenge. This research is a first glance at the possibilities to create a feasible retrofit …

Ammonia is heavily used in agriculture as a fertilizer and in industry as a raw material for the production of various organic nitrogen compounds. Its high hydrogen content and its established infrastructure for both storage and distribution makes ammonia a prominent candidate for storing fluctuating …

The Nieuw Statendam is equipped with a program called ENIRAM. This program calculates the optimal engine configuration and load expressed in revolutions per minute of the propellers. The issue with this program is that it only looks at the main power plants and does not take the waste heat recovery system …

The aim of this report is to document the configuration, design and testing of an innovative hybrid electric weed brush to be carried by a Antonio Carraro SP5008 Hydrostaticly articulated multi-purpose maintenance tractor. This project is issued by Hissink Custom Made Machinery, as an graduate assingment …

The natural gas/diesel dual-fuel engine is an interesting technique to reduce greenhouse gas emission. A limitation of this concept is the emission of un-combusted methane. In this study we analyzed the influence of PFI gas-injection timing on cylinder to cylinder gas-distribution, and the resulting …

Aircraft require significant quantities of fuel in order to generate the power required to sustain a flight. Burning this fuel causes the release of polluting particles to the atmosphere and constitutes a direct cost attributed to fuel consumption. The optimization of various aircraft operations in different …

On the 15th of June 2018 during the State visit to Lithuania 3 universities signed an agreement to research Cryogenic fuels (bio)-LNG and Hydrogen in an optimized, ecological, coupled Hybrid Energy Networks in a value chain context. A few months later dr. ir. J. Dam presented the current status of the …

As part of a Masterclass on Small Scale LNG prof. dr. ir. J. Dam was invited to give a lecture on the possibilities in the future for LNG. The following topics were discussed;- Which technologies are maturing?- What new LNG applications can we expect in the future?- Where does hydrogen meet LNG?

A delegation of the Amsterdam Harbor Company came to Groningen to attend a presentation which was part of their visit to Entrance. Jacques Dam and Juliana Montoya Cardona took the lead in presenting their research in the role of LNG in Hybrid Energy Networks.
