One potential renewable energy resource is green gas production through anaerobic digestion (AD). However, only part of the biogas produced (up to 50-60%) contains the combustible methane; the remainder are incombustible gasses with the biggest being carbon dioxide. These gasses are often not used and …

Biogas is produced from biomass by means of digestion. Treated to so-called ‘green gas’, it can replace natural gas. Alternatively, biogas can be used to produce electrical power and heat in a combined heat power (CHP) installation. In 2014 global biogas production was only 1% of natural gas production. …

The demand of renewable energy in the European Union is increasing significantly in order to reduce CO2 emissions. Efforts are being made for further development of biomethane and hydrogen to use it as a clean and sustainable fuel for vehicles. However, biomethane and hydrogen contains impurities that …

Within the context of the research programme “Koenst), a natural gas (methane) fuelled heater (Prototype I1) for injection moulding has been developed. When tested, the first prototype of this natural gas fuelled heater showed cracks at some specific spots, especially certain corners inside the hull. …

The natural gas/diesel dual-fuel engine is an interesting technique to reduce greenhouse gas emission. A limitation of this concept is the emission of un-combusted methane. In this study we analyzed the influence of PFI gas-injection timing on cylinder to cylinder gas-distribution, and the resulting …

In the search for low greenhouse gas propulsion, the dual fuel engine provides a solution to use low carbon fuel at diesel-like high efficiency. Also a lower emission of NOx and particles can be achieved by replacing a substantial part of the diesel fuel by for example natural gas. Limitations can be …

Though there are different interpretations in the scholarly literature of what a social learning is: whether it is an individual, organisational, or collective process. For example, Freeman (2007), in his study on policy change in the public health sector, conceptualised collective learning of public …

Presentatie over een aardbeving-vrij Groningen met natuurlijk gas.

The earthquakes after the natural gas extraction in the Groningen region of the Netherlands have a significant impact on the housing market and sustainability of the communities. Since the strongest earthquake around the community of Huizinge in August 2012, with a magnitude of 3.6 on the Richter scale, …
