Netcongestie belemmert de energietransitie, waardoor energieopslag belangrijker wordt. Lithium-ion batterijen zijn gangbaar, maar niet duurzaam en mogelijk schaars. Dit onderzoek verkent alternatieven: waterstofbatterijen en watertorens. Door klimaatverandering ontstaan risico’s zoals watertekort en …

In dit onderzoek wordt beoordeeld of batterijopslag op melkveebedrijven financieel rendabel is wanneer zij werken met dynamische energiecontracten. Er is te zien dat pieken in zonne-energieproductie, netcongestie en het afbouwen van de salderingsregeling de behoefte aan eigen opslag vergroten. Interviews …

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 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 …

Afstudeerwerkstuk ´Energieopslagsystemen´SamenvattingDit afstudeeronderzoek richt zich op de vraag of het rendabel is voor Pluimveebedrijf van Haare omeen energieopslagsysteem aan te schaffen. Momenteel koopt het bedrijf energie in op momentenvan vraag en levert het bedrijf energie terug wanneer er overschot …

The need for increasing further the penetration of Renewable Energy Sources (RESs) is demanding a change in the way distribution grids are managed. In particular, the RESs intermittent and stochastic nature is finding in Battery Energy Storage (BES) systems its most immediate countermeasure. This work …

A number of studies have investigated the possibility of extending Electric Vehicle (EV) Lithium-ion battery life by deliberately choosing to store the battery at a low to moderate state of charge. Recently, there has been considerable interest shown in the scheme of a deliberate discharge and subsequent …

OBJECTIVES: To evaluate the clinical performance of partial glass-ceramic (IPS e.max Press) posterior restorations. MATERIALS AND METHODS: A total of 765 restorations in 158 patients were placed between 2008 and 2018 and evaluated in a prospective study during regular dental care visits between 2015 …

The Vulkan real estate site in Oslo is owned by Aspelin Ramm, and includes one of the largest parking garages used for EV charging in Europe. EV charging (both AC and DC) is managed for now predominately for costs reasons but also with relevance at further EV penetration level in this car parking location …

This prospective randomized clinical trial evaluated tooth sensitivity and patient satisfaction after the provision of partial ceramic restorations bonded using immediate (IDS) or delayed dentin sealing (DDS) on vital molar teeth through a within-subject comparison study. Between December 2013 and May …
