Het Nederlandse elektriciteitsnet staat onder druk. Zonnepanelen, warmtepompen en laadpalen vragen meer van een infrastructuur die daar niet voor gebouwd is. De congestie is het hardst voelbaar op het middenspanningsnet — de regionale bottle­necks waar jarenlange wachtrijen voor nieuwe aansluitingen …

Purpose: Children’s physical education (PE) motivation is vital for their development and health and can be fostered by satisfying the needs for autonomy, competence, and relatedness. Yet, not all children have positive need-satisfying and motivational PE experiences. We examined individual differences …

This report describes the development of a prototype for a device that can charge and secure the Luna Glass, Luna’s flagship product. The assignment was to create the hardware and software necessary to facilitate a device that can charge the Luna Glass with room for future changes. The development is …

The growing adoption of residential and community-based photovoltaics (PV) have raised concerns about grid congestion and transformer overload. This paper evaluates three strategies for PV–battery integration in decentralised energy communities using real network and residential data to address these …

To reduce greenhouse gas emissions, countries around the world are pursuing electrification policies. In residential areas, electrification will increase electricity supply and demand, which is expected to increase grid congestion at a faster rate than grids can be reinforced. Battery energy storage …

A replacement of cars with conventional internal combustion engines (ICEs) by electric vehicles (EVs) is seen by many as a means to improve local air quality, reduce dependence on fossil fuels and CO2 emissions. The market for EV is slowly developing with a growing number of (subsidized) manufacturers …

The SteamBox is a startup that focuses on their innovative product; SteamBox. It is a self-heating lunchbox that uses steam to warm up the food inside of it. It is composed of a main container that stores the batteries as well as the heating system, and of a separate container meant for the food. When …

The global clean energy transition goals require commitment from every country. Different locations however present different technical and economic viability for increasing the penetration of variable renewable energy (VRE) resources to meet national targets. This work presents a comparative economic …

The intermittency of renewable energy technologies requires adequate storage technologies. Hydrogen systems consisting of electrolysers, storage tanks, and fuel cells can be implemented as well as batteries. The requirements of the hydrogen purification unit is missing from literature. We measured the …

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 …
