This study focuses on the feasibility of electric aircraft operations between the Caribbean islands of Aruba, Bonaire, and Curaçao. It explores the technical characteristics of two different future electric aircraft types (i.e., Alice and ES-19) and compares their operational requirements with those …

Lebanon’s economic crisis has disrupted the country’s energy and water sectors, highlighting their interdependence. The methodology involves surveying 150 municipalities across all Lebanese governorates, ensuring a comprehensive coverage of public and private water resources. Data on water and energy …

Several studies have shown that flying electric between the so-called ABC-islands in the Caribbean (i.e., Aruba, Bonaire and Curaçao) is feasible with the upcoming first generation of battery-electric aircraft. This paper presents a real-world case study that deals with the technical and operational …

End-stage kidney disease patients treated with conventional hemodialysis (CHD) are known to have impaired physical performance and protein-energy wasting (PEW). Nocturnal hemodialysis (NHD) was shown to improve clinical outcomes, but the evidence is limited on physical performance and PEW. We investigate …

This study aims to check the performance of two distinct configurations system: a photovoltaic-thermal (PVT) system with an ice buffer storage tank figure [1] and a conventional PV system with an air heat exchanger on the back, figure [3]. The ice buffer storage tank is used to store excess heat from …

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 …

Solar Boat, the project was born in 2009 by a group of enthusiastic students of mixed educational backgrounds who wanted to fill their free composition course points in a special, more meaningful way. They came in contact with DTIW and established an agreement of what they could offer each other, eventually …

Renewable energy systems are a crucial technological development needed to combat climate change. This thesis covers the design and implementation of a mathematical optimization model, which calculates the lowest cost of hydrogen for certain renewable energy system configurations. The output of the model …

A few years ago the Dutch government set goals for sustainability. These goals include switching to fully sustainable energy production by 2050. Using only conventional sustainable energy production methods like solar panels and wind turbines will not result in achieving the set goals, so alternative …

This article addresses European energy policy through conventional and transformative sustainability approaches. The reader is guided towards an understanding of different renewable energy options that are available on the policy making table and how the policy choices have been shaped. In arguing that …
