(author)Steel production is a main source of CO2 emissions globally. These emissions must be drastically reduced to meet climate change mitigation goals. STEPWISE is a Sorption Enhanced Reactive Process (SERP) technology that converts steel works arising gases to H2 with simultaneous CO2 capture. The main energy requirements of the process are the high-...article 2022

(author)Natural gas based hydrogen production with carbon capture and storage is referred to as blue hydrogen. If substantial amounts of CO2 from natural gas reforming are captured and permanently stored, such hydrogen could be a low-carbon energy carrier. However, recent research raises questions about the effective climate impacts of blue hydrogen...article 2022

Lap, T. (author), Daioglou, V. (author), Benders, R. (author), van der Hilst, F. (author), Faaij, A. (author)Land-use change (LUC)-related greenhouse gas (GHG) emissions determine largely whether bioenergy is a suitable option for climate change mitigation. This study assesses how LUC emissions influence demand for bioenergy to mitigate GHG emissions, and how this affects the energy mix, using Brazil as a case study. A methodological framework is...article 2022

Wildenborg, T. (author), Loeve, D. (author), Neele, F. (author)A plan was developed for large-scale transport and storage of CO2, inspired by the measures in The Netherlands Climate Agreement to reduce greenhouse gas emissions to the atmosphere. The main focus was on reduction of CO2 emissions captured from large industrial sources in the Rotterdam harbour area (Rijnmond region). CO2 storage potential is...article 2022

Tang, C. (author), Tukker, A. (author), Sprecher, B. (author), Mogollon, J.M. (author)The European Union (EU) has set a 37.5% GHG reduction target in 2030 for the mobility sector, relative to 1990 levels. This requires increasing the share of zero-emission passenger vehicles, mainly in the form of electric vehicles (EVs). This study calculates future GHG emissions related to passenger vehicle manufacturing and use based on stated...article 2022

van 't Westende, J.M.C. (author), van Nimwegen, A.T. (author), Belfroid, S.P.C. (author), Slot, H.J. (author)Experiments were performed to investigate the physics behind intermittent production and liquid loading, using a setup containing a reservoir model coupled to a vertical production tubing. In the experiments both gas and liquid are injected into the reservoir, which is a container in which sand with two different permeabilities is placed. Quick...conference paper 2021

Hunicz, J. (author), Mikulski, M. (author), Rybak, A. (author)Controlled auto-ignition (CAI) is an advanced combustion technology offering high thermal efficiency and low NOX emissions. One promising approach to achieve CAI combustion is application of negative valve overlap resulting in internal exhaust gas re-circulation. However, combustion control is still an issue which should be resolved before wide...conference paper 2018
