Several pathways for potentially greenhouse gas neutral production of ammonia have been investigated compared to today's conventional ammonia production at chemical sites in Antwerp, Dormagen, and Geleen. These pathways include on-site water electrolysis using grid electricity, off-site production via water electrolysis using renewable...

Process intensification in a membrane reactor is an efficient and compact way to produce hydrogen. A methane-rich gas mixture that simulated the composition of pre-reformed naphtha (PRN; with a steam-to-carbon ratio of 2.7) was reformed at temperatures of 55 degrees Celsius - 625 degrees Celsius and pressures up to 40 barg. The reactor contained...

Because of differences in irradiation levels, it could be more efficient to produce solar electricity and hydrogen in North Africa and import these energy carriers to Europe, rather than generating them at higher costs domestically in Europe. From a global climate change mitigation point of view exploiting such efficiencies can be profitable,...

AEMWE is a novel technology combining the advantages of the already recognized electrolyzer technologies, i.e. Proton Exchange Membrane WE (PEMWE) and Alkaline WE (AWE) with the promise to eliminate the disadvantages of both. This review presents an overall opinion of the current state of AEMWE technology, focusing on component’s performance,...

Ten aanzien van technologieën voor groene waterstof is er nader onderzoek nodig om de afhankelijkheid van essentiële grondstoffen te verminderen, en is er nationaal en Europees beleid nodig om de beschikbaarheid van deze grondstoffen veilig te stellen. Om met de thans beschikbare elektrolysetechnologieën (zoals PEM en AEL) aan de toekomstige...

Green hydrogen technologies require further research to reduce dependence on critical materials as well as both national and EU-level policies to secure their availability. In the previous paper we showed that meeting future European hydrogen demand (FCH Ambitious Scenario of 8100 PJ in 2050) using currently available technologies, such as...

A combined density functional theory and molecular dynamics approach is employed to study modifications of graphene at atomistic level for better H2 storage. The study reveals H2 desorption from hydrogenated defective graphene structure, V222, to be exothermic. H2 adsorption and desorption processes are found to be more reversible for V222 as...

Als je besluit een huis te bouwen, weet je dat je daarvoor grondstoffen nodig zult hebben. Je weet ook dat die grondstoffen waarschijnlijk ruim voorhanden zullen zijn. Wanneer je een volledig nieuw duurzaam energiesysteem gaat bouwen, heb je vanzelfsprekend ook snel toenemende voorraden nodig. Met de mogelijke leveringsrisico's van sommige ...

When you decide to build a house, you know you will need materials in order to do so. You also know that those materials will probably be readily available. When constructing a completely new sustainable energy system, you self-evidently need rapidly increasing levels of supplies as well. However, the potential supply risks for some ‘exotic’ ...

Low activation energy (Ea) and wide bandgap (Eg) are essential for (p)-contacts to achieve effective hole collection in silicon heterojunction (SHJ) solar cells. In this work, we study Plasma-Enhanced Chemical Vapor Deposition p-type hydrogenated nanocrystalline silicon oxide, (p)nc-SiOx:H, combined with (p)nc-Si:H as (p)-contact in front/back...

Selective hydrogenations in the aqueous phase are an important transformation in the context of developing biorefinery concepts. In this report the application and optimisation of nitrogen-doped carbon (NDC) supported Pd nanoparticles as hydrogenation catalysts is discussed in the context of directing support (e.g. N) chemistry for improved...

This mini-review presents an overall opinion of the technological challenges associated with each component of PEMWE at the cell level. State-of-the-art and a selection of novel advances in PEMWE technology are presented in order to put the performance and limitations of each component in the context followed by our perspective for strategies in...

In this follow-up study the collaboration between two research groups from the USA and the Netherlands was continued to expand the framework of chemical attribution for the homemade explosive erythritol tetranitrate (ETN). Isotope ratio mass spectrometry (IRMS) analysis was performed to predict possible links between ETN samples and its...

Wind generation on the North Sea is rapidly expanding. Offshore wind generation is expected to be a major source of energy for the future carbon-free energy system. The onset of this rapid growth is already visible. In the IJmuiden Ver area, 80 kilometres off the coast at Den Helder, a wind park expansion of 4 GW is planned by 2030, and possibly...

This review covers the research and industrial activities on mainly Ga- and Zn-promoted ZSM-5 catalysts for the production of bio-aromatics in the thermochemical conversion of biomass and waste. The promoted ZSM-5 catalysts currently favoured in biomass aromatization have not initially been designed for biomass processing, but for the conversion...

Humins, a by-product of biomass chemical conversion technologies, still present controversies in their structural and mechanistic identification. Traditional studies of the structure and mechanism have focused so far on their syntheses from key molecules (sugars, HMF) and spectroscopic analyses of the as-synthesized oligomers/macromolecules....
