Air pollution is an important aspect for transportation, particularly car emission in urban area. The objective of this paper is to evaluate the global emission of a transport network based on probe car and traffic sensor data. This paper used the microsim ...
Current and future dynamics, of environmental legislations and trading market, of the fuel and electricity prices due to the market liberalization or resource shortages, and of the innovations of power/cogeneration technologies, impose great challenges on ...
Selective process modifications were considered among the possible process variations for carbon dioxide separation in natural gas fired combined gas and steam turbine power plants that differ greatly among themselves in terms of additional expense (effici ...
Goal and Scope. This paper aims to develop continental characterization factors for the human toxicity impacts of emissions released to air in different continents and to analyze under which conditions this spatial distinction makes a significant differenc ...
Unscavanged prechamber ignition has been developed at the Laboratory of Industrial Energy Systems to reduce the emissions from cogeneration spark ignition gas engines, operating with both natural gas and biogas. Demonstration has been made that a lean burn ...
This paper investigates the effectiveness of voluntary approaches in a comparative case study on European and Swiss climate legislation. Voluntary approaches are known to be less environmentally effective and economic efficient than other climate policy in ...
A novel ignition concept based on autoignition in an unscavanged prechamber is currently being developed at the Laboratory for Industrial Energy Systems (LENI). On a single cylinder test engine a series of experimental runs (CR=8.5-14, =1-1.6, RPM=1150/150 ...
The most common energy application for biogas is on-site power generation using gas engine units. The introduction of a bottoming cycle based on Scroll expander Organic Rankine Cycle (ORC) technology within a biogas plant is of high interest since the exce ...
This study reports on the combination of solid oxide fuel cell (SOFC) generators fueled with biogas as renewable energy source, recoverable from wastes but at present underexploited. From a mobilisable near-future potential in the European Union (EU-15) of ...
This work is part of ongoing research on stationary natural gas engines equipped with unscavanged prechambers. Spark ignition inside the prechamber has been successfully proven with natural gas as well as biogas, reducing emissions while keeping good effic ...
