A small cogeneration system based on a Solid Oxide Fuel Cell (SOFC) fed on the renewable energy source biogas is presented. An existing farm biogas production site (35 m3 per day), currently equipped with a SOFC demonstration stack, is taken for reference. ...
Abstract: A short overview of recent work on electroceramic materials relevant to methane-fueled SOFC systems is given. Various fuel feed options are considered, such as pure methane, biogas, and the addition of reforming agents. The principle and implemen ...
In the order to produce energy for the large amount of people still currently out of the national girds, different possibilities exist. For practical and economic reasons, the most popular one is the use of Diesel engines coupled with generator sets. Petro ...
THE ENVIRONMENTAL IMPACT OF NATURAL GAS VEHICLES The natural gas vehicle (NGV) presents one of the few options to current automobile related environmental problems that is both feasible with today’s technology and commercially viable. NGV technology is not ...
The title of this paper, “Against the Odds - Switzerland and the Emergence of NGV’s”, written some time ago reflects an expectation based on test results and considerable market interest. Unfortunately at the time of writing Switzerland is still awaiting t ...
Cross-field transport of test ions is investigated in a linear Q-machine plasma. Test particles are created and followed in their motion by an optical tagging diagnostic scheme. Diffusion is demonstrated to be supported by classical mechanisms. When differ ...
Converting wood to grid quality methane allows to distribute a CO2 free, renewable enery resource in a conventional energy distribution system and use it in transportation applications. Using a previously developed thermo–economic process model for thermoc ...
Test of the unscavenged prechamber ignition system on a 150kW cogeneration engine fed with biogas are presented. The objective was to reach at least 36% in fuel conversion efficiency with exhaust gas emissions lower than the Swiss regulations limits (NOx, ...
The process design of a 10 to 20MWth Synthetic Natural Gas (SNG) production process from wood has been performed. Combining process modeling and process integration techniques, this study proceeds via the following stages: • thermodynamic modeling: mass, e ...
JET plasmas with reverse magnetic field feature a different SOL flow than those with normal field. The observed carbon fuelling efficiency from injecting methane gas was similar in reverse and normal field. EDGE2D modeling used an externally applied force ...
