Shallow gas accumulates in coastal marine sediments when the burial rate of reactive organic matter beneath the sulfate zone is sufficiently high and the methanogenic zone is sufficiently deep. We investigated the controls on methane production and free me ...
A boreal bog located in the James Bay lowlands, Canada, was instrumented with an open-path gas analyzer to monitor the turbulent fluxes of methane throughout the summer of 2012. The mostly continuous eddy covariance measurements permitted the study of meth ...
Biomethane potential (BMP) tests are a valuable tool to design different parts of full-scale anaerobic digestion plants. Recent inter-laboratory studies have shown that the results of BMP tests can vary considerably and a comparison of BMP test norm protoc ...
Biomass is a renewable, yet scarce resource since land is limited. This thesis addresses the question how to efficiently convert the available lignocellulosic biomass and biomass wastes to fuel and other useful energy services. In particular, it presents a ...
Different technological alternatives for the thermochemical production of liquid fuels from lignocellulosic biomass are systematically analyzed and optimized based on thermo-environomic models. The competitiveness of the production of Fischer-Tropsch fuel ...
The thermochemical production of hydrogen from lignocellulosic biomass is systematically analyzed by developing environomic models combining thermodynamics with economic analysis, process integration techniques and optimization strategies for the conceptua ...
The conversion of lignocellulosic biomass to methane is a promising way to distribute a renewable resource as a versatile energy vector in an existing grid. Potentially more efficient than the production of liquid fuels, it can be used as Synthetic Natural ...
Biogas is a fuel made from the anaerobic digestion of organic material to form methane. It can be used to power a stationary engine to generate electricity making it a viable method of decentralised power generation from renewables. However, biogas is a mi ...
The main challenges associated with a growing production of renewable electricity are intermittency and dispersion. Intermittency generates spikes in production, which need to be curtailed when exceeding consumption. Dispersion means electricity has to be ...
Even though lakes only occupy a small percentage of Earth's surface, they represent a natural source of methane, contributing substantially to methane emissions and ultimately to global warming. There is extensive evidence that methane emissions from lakes ...
