Hendriks, A.T.W.M. (author), van Lier, J.B. (author), de Kreuk, M.K. (author)Fermentation and anaerobic digestion of organic waste and wastewater is broadly studied and applied. Despite widely available results and data for these processes, comparison of the generated results in literature is difficult. Not only due to the used variety of process conditions, but also because of the many different growth media that are...journal article 2018

(author)The world's future energy supply will include intermittent renewable sources, such as solar and wind power. To guarantee reliability of supply, fast-reacting, dispatchable and renewable back-up power plants are required. One promising alternative is parked and grid-connected hydrogen-powered fuel cell electric vehicles (FCEVs) in "Vehicle-to...journal article 2018

Chen, Z. (author), Dang, Jie (author), Hu, Xiaojun (author), Yan, Hongyan (author)Hydrogen has received much attention in the development of direct reduction of iron ores because hydrogen metallurgy is one of the effective methods to reduce CO<sub>2</sub> emission in the iron and steel industry. In this study, the kinetic mechanism of reduction of hematite particles was studied in a hydrogen atmosphere. The phases and...journal article 2018

Safaei Farahani, S. (author), van der Veen, R.A.C. (author), Oldenbroek, V.D.W.M. (author), Alavi, F. (author), Park Lee, E.H. (author), van de Wouw, N. (author), van Wijk, A.J.M. (author), De Schutter, B.H.K. (author), Lukszo, Z. (author)In recent years, the European Union (EU) has set ambitious targets toward a carbon-free energy transition. Many studies show that a drastic reduction in greenhouse gas emissions-at least 90% by 2050-is required. In the transition toward a sustainable energy system, solar (or green) hydrogen plays many important roles, as it is a clean and safe...journal article 2019

Fernández-Dacosta, Cora (author), Shen, Li (author), Schakel, Wouter (author), Ramirez, Andrea (author), Kramer, Gert Jan (author)The deployment of low-emission alternative fuels is crucial to decarbonise the transport sector. A number of alternatives like hydrogen or dimethyl ether/methanol synthesised using CO<sub>2</sub> as feedstock for fuel production (hereafter refer to “CO<sub>2</sub>-based fuels”) have been proposed to combat climate change. However, the...journal article 2019

JIMENEZ RODRIGUEZ, C.D. (author), Coenders-Gerrits, Miriam (author), Uhlenbrook, S. (author), Wenninger, J.W. (author)The implementation of afforestation programs in arid environments in northern China had modified the natural vegetation patterns. This increases the evaporation flux; however, the influence of these new covers on the soil water conditions is poorly understood. This work aims to describe the effect of Willow bushes (Salix psammophila C. Wang...journal article 2019

Robledo, C.B. (author), van Leeuwen, Lotta (author), van Wijk, A.J.M. (author)The need for zero emission drive is a global necessity that can contribute to mitigate greenhouse gas emissions. In this context, fuel cell hybrid electric vehicles are increasingly attracting interest by governments, companies and academia. While parked they can operate as power generation units, given the proper connection to the electricity...journal article 2019

Olindo, Roberta (author), Vogtländer, J.G. (author)Desulphurization of oil-based fuels is common practice to mitigate the ecological burden to ecosystems and human health of SO<sub>x</sub> emissions. In many countries, fuels for vehicles are restricted to 10 ppm sulphur. For marine fuels, low sulphur contents are under discussion. The environmental impact of desulphurization processes is,...journal article 2019

Riemersma, B. (author), Kunneke, R.W. (author), Reniers, G.L.L.M.E. (author), Correljé, A. (author)This paper argues that energy systems are becoming increasingly complex, and illustrates how new types of hazards emerge from an ongoing transition towards renewable energy sources. It shows that the energy sector relies heavily on risk assessment methods that are analytic, and that systemic methods provide important additional insights.Acase...journal article 2020
