(author), Denier van der Gon, H.A.C. (author), Röckmann, T. (author)Natural gas is considered a bridging technology in the energy transition because it produces fewer carbon emissions than coal, for example. However, when leaks exist, methane is released into the atmosphere, leading to a dramatic increase in the carbon footprint of natural gas, as methane is a much stronger greenhouse gas than carbon dioxide....article 2023

(author)This study demonstrates the ability of large-eddy simulation (LES) forced by a large-scale model to reproduce plume dispersion in an actual field campaign. Our aim is to bring together field observations taken under non-ideal conditions and LES to show that this combination can help to derive point-source strengths from sparse observations. We...article 2022

Delre, A. (author), Hensen, A. (author), Velzeboer, I. (author), Bulk, P.V.D. (author), Edjabou, M.E. (author), Scheutz, C. (author)Site-specific methane (CH4) and ethane (C2H6) emission rates from the onshore oil and gas (O&G) sector in Romania were quantified, using the mobile tracer gas dispersion method. As part of the coordinated Romanian Methane Emission from Oil & Gas measurement campaign, this study supported the investigation of CH4 emissions from the O&G sector...article 2022

Hensen, A. (author), Velzeboer, I. (author), Frumau, K.F.A. (author), van den Bulk, W.C.M. (author), van Dinther, D. (author)Methane is a potent greenhouse gas with an equivalent greenhouse warming potential of 25-35 of CO2 equivalents. There is an increasing regulatory effort to reduce methane emissions, including methane emissions from natural gas production. Oil and gas operators in the Netherlands report already for more than 20 years their annual methane...report 2019

Velzeboer, I. (author), Blom, M.J. (author), Duyzer, J.H. (author)This report describes a study in which the air purifying efficiency of selected systems was investigated under realistic, reproducible laboratory conditions. The aim of this study was primarily to determine the potential of air-purifying plant systems (plants with ventilation systems) to remove particulate matter (PM) and volatile organic...report 2019

van Zomeren, A. (author), Velzeboer, I. (author), Energieonderzoek Centrum Nederland (author)The objective of this report is to study the consistency of the EoW criteria among different European countries. In the Netherlands there is one regulation with EoW criteria, specifically for construction and demolition waste. Comparable regulations for inert aggregates are available for the United Kingdom, France and Austria. These EoW criteria...report 2017
