Zhou, Jianmin (author), Ding, Lei (author), Shi, Mu (author), Lindeboom, R.E.F. (author), Cui, Changzheng (author)In the envisaged hydrogen economy, H<sub>2</sub> could be an interesting alternative electron donor for the denitrification of drinking water or wastewater. The main obstacle to engineering the hydrogenotrophic denitrification process is the low solubility of H<sub>2</sub> in water under atmospheric pressure, which limits denitrification rate...journal article 2022

Van Der Slikke, Deanne (author), Guerra, Karla (author), de Jong, W. (author), Haro, Pedro (author)Hydrogen is believed to be an important energy vector in the transition to a more sustainable future. However, there is a scarcity of relevant studies analysing the realistic potential for hydrogen production in specific European regions. In this study, the potential for biomass-derived hydrogen is comprehensively analysed considering a...journal article 2021

(author)Many Unmanned Air Vehicle (UAV) applications require vertical take-off and landing and very long-range capabilities. Fixed-wing aircraft need long runways to land, and electric energy is still a bottleneck for helicopters, which are not range efficient. In this paper, we introduce the NederDrone, a hybrid lift, hybrid energy hydrogen-powered...journal article 2021

Van de Graaf, Thijs (author), Overland, Indra (author), Scholten, D.J. (author), Westphal, Kirsten (author)While most hydrogen research focuses on the technical and cost hurdles to a full-scale hydrogen economy, little consideration has been given to the geopolitical drivers and consequences of hydrogen developments. The technologies and infrastructures underpinning a hydrogen economy can take markedly different forms, and the choice over which...journal article 2020

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

(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
