Quality control of large-scale monitoring networks requires the use of automatic procedures to detect potential outliers in an unambiguous and reproducible manner. This paper describes a methodology that combines existing statistical methods to accommodate for the specific characteristics of measurement data obtained from groundwater quality...

Fast pyrolysis is an efficient technology to convert lignocellulosic biomass to a liquid product. However, the high contents of oxygenated compounds and water hinder the direct utilization of pyrolysis oils. Here, we report an upgrading concept to obtain liquid products with improved product properties and enriched in valuable low molecular...

Met het Datapakket Eindgebruikerskosten krijgen gemeenten inzicht in de eindgebruikerskosten van verschillende warmtestrategieën (zie Tabel S.1). Eindgebruikerskosten zijn het saldo van de jaarlijkse kosten en baten (met name door energiebesparing) van het toepassen van warmtestrategieën uit de Leidraad voor eindgebruikers. Eindgebruikers zijn...

History matching can play a key role in improving geological characterization and reducing the uncertainty of reservoir model predictions. Application of reservoir history matching is restricted by the huge computational cost by amongst others the many runs of the full model. Surrogate models with a reduced complexity are therefore used to...

Feedstock flexibility is highly advantageous for the viability of (solvent-based) biorefineries but comes with the considerable challenge of having to cope with the varying nature and typically high abundance of nonlignocellulose compounds in the most readily available residual biomass streams. Here, we demonstrate that mild aqueous acetone...

Offshore wind farms are an important energy source in the worlds current energy transition toward a CO2 neutral energy system. For the development of offshore windfarms in the North Sea a solid understanding of the geology and geotechnicalparameters of the uppermost 150 m of the seabed sediments is essential. The Geological Survey of the...

In 2017, the (then) Energy research Centre of the Netherlands (ECN) published the major findings of the FLEXNET project on the demand and supply of flexibility by the power system of the Netherlands over the years 2015-2050 (Sijm et al., 2017a, 2017b and 2017c). In 2018, ECN joined forces with TNO and, subsequently, merged into the unit Energy...

Humidification is not a common procedure in many buildings in the Netherlands. An exception are buildings used for healthcare, especially hospitals. There, e.g. in operating theatres, relative humidity (RH) generally is controlled stringently at levels around 50%. From an energy point-of-view humidification is an energy-intensive activity....

Het doel van dit onderzoek is het Ministerie van Economische Zaken en Klimaat een overzicht te bieden van mogelijke beleidsinstrumenten inclusief de wijze waarop de overheid hiermee de ontwikkeling van warmtenetten als alternatief voor de huidige warmtevoorziening op aardgas financieel kan ondersteunen. Eerst is een analysekader gemaakt dat de...

Reduction of greenhouse gas emissions implies electrifying demand and decarbonising electricity production. Decarbonising electricity production is for the most part achieved by increasing the production from variable renewable energy (VRE) sources. The increasing share of VRE production increases demand for flexibility to balance supply and...

In het CATCH-IT (2012 .. 2015) project is een stoom producerende compressie warmtepomp ontwikkeld waarmee restwarmte van 50˚C tot 80˚C kan worden opgewaardeerd tot lage druk stoom (tot 2,5 barg). De schaalgrootte was 200 kWth en er werd gebruik gemaakt van butaan als werkmedium. De warmtepomp is bij Smurfit Kappa Roermond Papier met het...

Presence of microannuli at the cement interfaces in wellbores could provide a path for fluid leakage. In this study, we combined experimental analysis and numerical modelling to assess microannuli development at casing–cement interfaces. Lab experiments were conducted using two-metre long samples consisting of a 7’’ casing cemented inside a rock...

In the present work, the high-temperature and long-term hydrothermal stability of novel polyPOSS-imide membranes for high-temperature hydrogen separation is investigated. The polyPOSS-imide membranes are found to exhibit an appropriate stability up to 300 C. Above this temperature the membrane selectivity rapidly decreases, which is seemingly...

Estuaries comprise channels vital for economic activity and bars as valuable habi tats. They are increasingly under human-induced pressures (e.g. sea-level rise and dredging), resulting in morphological changes that affect navigability, flood safety and ecology. Antecedent geology may strongly steer how estuary channels will adapt to these...

In the Dutch offshore, we have observed numerous acoustic anomalies, usually bright spots, in seismic data of Cenozoic deltaic deposits. When associated with shallow gas, these bright spots are good indicators of re source potential, drilling hazard, or seabed methane emissions. We apply a combined seismic and petrophysical assessment to qualify...

In this paper we identify drivers for energy poverty in Europe using machine learning. The establishment of predictors for energy poverty valid across countries is a call made by many experts, since it could pro vide a basis to effectively target energy-poor households with adequate policy measures. We apply a ‘‘low income, high expenditure”...

Incorporating (operational) flexibility into process design has been a key approach to cope with uncertainties. The increasing penetration of renewables and the need for developing new low-carbon technologies will increase the demand for flexibility in chemical processes. This paper presents a state-of the-art review focusing on the origin,...
