Understanding sludge rheology and optimizing equipment performance is crucial for energy efficiency in wastewater treatment plants (WWTPs). This study examined sludge rheology after thermal hydrolysis pretreatment (THP) at 60, 80, and 120 ◦C for 2 h, followed by anaerobic digestion (AD) at 37 ◦C for …

Electrification of residential areas is increasingly common. Major areas of development include rooftop solar panels, electric vehicles and heat pumps. However, existing grid components may have insufficient network capacity to accommodate the resulting electricity flows. Battery energy storage (BES) …

Electrification of residential areas is increasingly common. Major areas of development include promoting rooftop solar panels, electric vehicles and heat pumps. However, existing grid components may have insufficient capacity to support the resulting electricity flows. Battery energy storage (BES) can …

Het project “In twee stappen naar een aardgasvrije en comfortabele Nederlandse woonomgeving” ontwikkelt een manier om de overstap naar aardgasvrije woningverwarming eenvoudiger, minder spannend, betrouwbaarder en beter te maken. Dat doen we door een “hybride” tussenstap, die een behoorlijke aardgasreductie …

A prototype of an indoor monoblock heat pump was tested at multiple ambient temperatures, to determine heat output, COP and the impact of defrosting events. Component efficiencies and the ice accumulation process were analysed. Options to improve performance were suggested.

Presentatie voor bewoners van Zuidwolde (Groningen) om hen te informeren over opties voor duurzame installaties die toegepast kunnen worden voordat het lage temperatuur warmtenet wordt aangelegd.

In Vlissingen, the municipality wants to make a selected neighbourhood natural gas-free. In order to support this, they have been granted a subsidy. There are many important stakeholders in this project such as the housing corporation l’Escaut which owns most of the houses in the neighbourhood. All of …

Research has been done on how the implementation of heat pumps in dwellings could have the maximum impact on energy savings.

A major target of the European Green Deal is to raise the 2030 greenhouse gas emission reduction target to 55% compared to 1990. This high ambition includes an increase of the energy performance of buildings and additional generation of renewable energy in all sectors. The tertiary sector, including …
