Development of Specific Rules for the Application of Life Cycle Assessment to Carbon Capture and Storage
Strazza, Carlo; Borghi, Adriana Del; Gallo, Michela - In: Energies 6 (2013) 3, pp. 1250-1265
Carbon Capture and Storage (CCS) is a very innovative and promising solution for greenhouse gases (GHG) reduction,<i> i.e.</i>, capturing carbon dioxide (CO<sub>2</sub>) at its source and storing it indefinitely to avoid its release to the atmosphere. This paper investigates a set of key issues in the development...

Energy from Agricultural and Animal Farming Residues: Potential at a Local Scale
Fiorese, Giulia; Guariso, Giorgio - In: Energies 5 (2012) 9, pp. 3198-3217
Animal wastes from high-density farming have severe impacts on the nitrogen cycle. According to current regulations, the disposal of manure on cropland is constrained by nitrogen content in the agricultural soils. On the contrary, anaerobic digestion (AD) of these wastes can produce energy and a...

An Equivalent Emission Minimization Strategy for Causal Optimal Control of Diesel Engines
Zentner, Stephan; Asprion, Jonas; Onder, Christopher; … - In: Energies 7 (2014) 3, pp. 1230-1250
One of the main challenges during the development of operating strategies for modern diesel engines is the reduction of the CO<sub>2</sub> emissions, while complying with ever more stringent limits for the pollutant emissions. The inherent trade-off between the emissions of CO<sub>2</sub> and pollutants renders a...
