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 …

This paper seeks to make a contribution to business model experimentation for sustainability by putting forward a relatively simple tool. This tool calculates the financial and sustainability impact based on the SDG’s of a newly proposed business model (BM). BM experimentation is described by Bocken …

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 …

Background: In their research reports, scientists are expected to discuss limitations that their studies have. Previous research showed that often, such discussion is absent. Also, many journals emphasize the importance of avoiding overstatement of claims. We wanted to see to what extent editorial handling …

Taxi companies have been delivering booking apps in response to passengers’ raising expectations of being able to choose an affordable cab, when and where he or she desires. YourDriverApp is a new white label application developed by taxiID that is set to provide such booking apps to companies worldwide. …

Standing up is harder to perform when getting older. The company SillaPlus want to create a physical device that can be attached to already existing chairs and will help elderly people get up from a chair. The company reached out to students who want to help with the development of a get up aid. The …

A review has been completed for a verification and validation (V&V) of the (Excel) BioGas simulator or EBS model. The EBS model calculates the environmental impact of biogas production pathways using Material and Energy Flow Analysis, time dependent dynamics, geographic information, and Life Cycle analysis. …

The production of biogas through anaerobic digestion is one of the technological solutions to convert biomass into a readily usable fuel. Biogas can replace natural gas, if the biogas is upgraded to green gas. To contribute to the EU-target to reduce Green House Gases emissions, the installed biogas …

In this investigation the effect of a reward system on the internal motivation to play sports is measured in the hostel of Tactus Drug Rehabilitation. The investigation arised from a disappointing attendance at the sports. In the theoretical background several theories and studies are discussed. One …
