Within the Flexigas project a model has been constructed which can analyze the efficiency, carbon footprint and environmental impact of anaerobic biogas production chains.

The increase in renewable energy sources will require an increase in the operational flexibility of the grid, due to the intermittent nature of these sources. This can be achieved for the gas and the electricity grid, which are integrated by means of power-to-gas and vice versa, by applying gas and other …

In de textielindustrie wordt veel water gebruikt.Tijdens vrijwel alle veredelingsprocessen speel water een rol. In het Europese samenwerkingsverband 'The Textile flagships: TFE 2, from wet to dry ' wordt hierover nagedacht. De belangrijkste doelstelling is de textielindustrie in staat te stellen om …

Abstract written to Biogas Science for oral presentation. Regarding a new methodology for determining the energy efficiency, carbon footprint and environmental impact of anaerobic biogas production pathways. Additionally, results are given regarding the impacts of energy crops and waste products used …

In the field of ‘renewable energy resources’ formation of biogas is an important option. Biogas can be produced from biomass in a multistep process called anaerobic digestion (AD) and is usually performed in large digesters. Anaerobic digestion of biomass is mediated by various groups of microorganisms, …

In order to gain a more mature share in the future energy supply, green gas supply chains face some interesting challenges. In this thesis green gas supply chains, based on codigestion of cow manure and maize, are considered. The produced biogas is upgraded to natural gas quality and injected into the …

De onderhandelingen tussen de EU en de VS (Transatlantic Trade and Investment Partnership - TTIP) begonnen in 2013. Ze hebben als doel het slechten van handelsbarrières en het harmoniseren en standaardiseren van voorschriften. In de thesis wordt onderzocht, in hoeverre de regelgeving in de EU op het …

Increasing oil and energy demand asks for higher efficiency when it comes to oil recovery. To increase oil recovery efficiency, pore-scale mechanisms during waterflooding, a common recovery method, have to be better understood. This provides knowledge on the dynamic process during imbibition, which …

Doel van dit onderzoek is 1a. Is het mogelijk om een Critical Velocity (CV) te bepalen voor getalenteerde schaatsers? 1b. Rijden de proefpersonen op CV met een steady state in hun zuurstofopname? 2. Is er een relatie tussen slagfrequentie/e hoek en het kunnen volhouden van CV? Methode: De CV is bepaald …
