Political, economic and environmental impacts of biofuels

01/01/2014 · Corrected cost for cassava-based production ~759 €/ton bio-ethanol The production cost by appl ying a hybrid operation a nd/ or VHG, can reduce the total production cost by ~56 €/ton bio


Mayer et al. [48] described the use of a boiler for thermal fluid heating in a batch still; unsatisfactory operation resulted due to the cost of the thermal fluid, the insufficient heat transfer surface of the reboiler, the possibility of ethanol contamination by the thermal fluid and the extended time required to begin product withdrawal (2.5 h).

Ocean thermal energy conversion - Wikipedia

07/08/2002 · Ocean Thermal Energy Conversion (OTEC) uses the ocean thermal gradient between cooler deep and warmer shallow or surface seawaters to run a heat engine and produce useful work, usually in the form of electricity.OTEC can operate with a very high capacity factor and so can operate in base load mode.. The denser cold water masses, formed by ocean surface water interaction with cold

Maximizing cellulosic ethanol potentials by minimizing

01/12/2017 · Although the electricity consumption of cellulosic ethanol is obviously greater than corn ethanol (262.95 kWh vs. 34.46 kWh), cellulosic ethanol biorefining is a high electricity positive process with extra electricity generation by lignin residue and methane combustion. 1.51 tons of lignin residue (50% of pure lignin content, w/w) per metric ton cellulosic ethanol is produced in DryPB process

Operating costs of these stages have been estimated in 2008: (i) CO 2 separation from exhausting gases: 24 to 52 €/ton-CO 2, (ii) transportation to storage location: 1 to 6 €/ton-CO 2 per 100 km, (iii) storage: −28 to 42 €/ton-CO 2. Therefore, CO 2 separation is a major stage in CCS.
