Met duurzame warmtenetten is in Nederland nog weinig ervaring opgedaan terwijl ze wel een belangrijke rol kunnen spelen in de overgang naar een aardgasvrij warmtesysteem. Bestaande warmtenetten zijn doorgaans top-down georganiseerd en hebben vaak een slechte reputatie; veel klanten zijn ontevreden over …

In dit publieke rapport wordt waterstof als een aanvullende mogelijkheid voor verduurzaming van de warmtevoorziening in woonwijken gepresenteerd. Het demonstratieproject Waterstofwijk Hoogeveen dient hierbij als rode draad. Voor andere wijken zal per geval bekeken moeten worden of de waterstofoptie echt …

Wind turbines are usually clustered in wind farms which causes the downstream turbines to operate in the turbulent wakes of upstream turbines. As turbulence is directly related to increased fatigue loads, knowledge of the turbulence in the wake and its evolution are important. Therefore, the main objective …

In deze bijdrage wordt verslag gedaan van de afstudeertafels van het CBSS 2020 experiment, waar 29 studenten communicatie en international communication en 5 studenten van de Academie Minerva in deelnamen

Education is a key factor to respond to the threat of climate change, increasing not only knowledge but also encouraging changes in attitudes and behaviors to adopt sustainable lifestyles. Scholars and practitioners in the field of education call for innovative ways of engaging youth—a reason why gamification …

Dynamic stall phenomena carry the risk of negative damping and instability in wind turbine blades. It is crucial to model these phenomena accurately to reduce inaccuracies in predicting design driving (fatigue and extreme) loads. Some of the inaccuracies in current dynamic stall models may be due to …

Power-to-gas technologies are considered to be part of the future energy sys- tem, but their viability and applicability need to be assessed. Therefore, models for the viability of farm-scale bio-power-to-methane supply chains to produce green gas were analysed in terms of levelised cost of energy, energy …

New technologies or approaches are being widely developed and proposed to be deployed in real energy systems to improve desired objectives; however supporting decision making processes to select best solutions in terms of performance and efficient following cost-benefit analysis require some sort of …

Vibrational and structural properties of lead-free piezoelectric (1-x)Na0.5Bi0.5TiO3–xCaTiO3 (0 < x < 1.00) solid solutions have been investigated using Raman spectroscopy and X-ray diffraction. Different anomalies were detected and analyzed taking into consideration the phase transition from rhombohedral …
