de Vries, David (author)Ethiopia’s energy demand is expected to increase sevenfold in the coming 30 years, resulting in increased variable renewable electricity (VRE) production by solar PV and wind. Energy storage acts as a buffer that mitigates the effects of over- or under-capacity in production by VRE. With 97% of global bulk energy storage, pumped hydro storage is...master thesis 2023

Dekker, Victor (author)Due to financial and environmental benefits, the interest in high-temperature heat pumps, producing heat sinks above 100 °C, is rising. Research is intensifying, and technology is developing fast. However, of all the components of the heat pump cycle, the oil management system seems to be the least investigated, even though 12% of the faults in...master thesis 2023

Bunikyte, Ugne (author)To face the ongoing climate crisis, the Dutch government adopted a number of policies and measures to limit its greenhouse gas emissions. It is estimated that 10% of Dutch annual emissions are caused by the built environment, a large portion of which come from two sources: space heating and domestic hot water.<br/>The use of heat pumps is said...master thesis 2022

Lambregts, Dorien (author)The production and consumption of electricity need to be balanced at all times. Due to the ever-growing shift towards renewable energy generation, this poses an increasingly difficult challenge. Currently, supply is regulated to maintain balance. However, there is potential to improve reliability and save costs by shifting the balancing to the...master thesis 2022

Vermani, Sanjay (author)Industrial processes are estimated to be responsible for about 20 % of the total greenhouse gas emissions within the European Union (EU). The majority of the industrial energy demand is related to the thermal energy required for process heating. Thus, there is a need to make radical changes to the industrial heating supply to achieve net-zero...master thesis 2022

Bokil, Siddharth Rahul (author)The heating and cooling sector is one of the biggest sectors at this moment due to drastic fluctuations in climate parameters. Even though this sector helps in making sure everyone gets comfortable temperatures at the home, office, etc., there are environmental consequences attached to them. These consequences are in terms of emissions of...master thesis 2022

Scherer, Tormo (author)European and Dutch environmental goals prescribe that national emitted CO2 levels need to be reduced. Therefore, the Dutch government chose to transition the whole Dutch residential sector to gas-free living by 2050, to decrease CO2 levels. Homeowners are responsible themselves for adopting a sustainable heating system, where specifically heat...master thesis 2022

LIN, WEI CHUN (author)Since everyone’s body, needs, and goals are unique, frequent and close interactions with unsuitable products can result in negative physical and mental experiences. Yet breast pumps are still mass-produced products, and finding the right product for themselves can be challenging for mothers. As a result, a new design strategy, product...master thesis 2022

Lin, J. (author)Estuaries are the core area of land-sea interactions and have significant ecological and economic value. In estuaries, hydrodynamics and sediment dynamics are the crucial processes governing geomorphology, navigability, and primary production. Since the turn of the 20th century, increased human activities (e.g., damming, dredging, and...doctoral thesis 2022

kleyn Winkel, Lars (author)By placing multiple Peltier elements in a linear arrangement while two water flows run past the elements, a temperature increase can be realised in one flow while the other flow is cooled down. In this study the heating of domestic hot water with Peltier elements as solid state heat pumps, and a heating network was investigated. A numerical...master thesis 2022
