Possibilities of creating zero CO2 emissions industrial plants due to energy use in Crete, Greece
Although the reduction of CO2 emissions due to energy use in industries is of paramount importance, there are not many successful examples of zero CO2 emissions industries so far. The possibility of creating zero CO2 emissions industries due to heat and electricity use in Crete, Greece has been investigated. Energy consumption and CO2 emissions in five small-size industries have been estimated. It has been indicated that the use of locally available renewable energy sources like solar energy and solid biomass could cover all the heat and electricity needs in those five industries zeroing their CO2 emissions. Solar-PV energy with the net-metering initiative could be used in order to offset annually the grid electricity use. Olive kernel wood is a low-cost renewable fuel which already is widely used in Crete for heat generation. Its use could replace the use of oil for industrial heating. The solar-PV investment in those plants is economically viable due to the current low cost of these energy systems. Therefore the use of renewable energy technologies in those industries could cover all their heating and power needs, zeroing their carbon emissions. The results indicate that the use of various locally available and cost-effective renewable energies could also zero carbon emissions in other industries without requiring public financial support.
