The D-ploy project (Deploying large-scale polygeneration in industry) aims at identifying and helping remove the barriers to the deployment of large-scale co/polygeneration technologies in European industry. The project brings together high level experts from industry and specialised consultancies in an effort to analyse the drivers for investments in co/polygeneration in the following industrial sectors: pulp and paper, chemicals, mineral oil refineries and food processing. Besides the analysis of the policy backdrop and the economic and financial considerations, the D-ploy project is breaking new ground by creating a map of all large-scale installations in the aforementioned sector and highlighting those sites that are implementing co/polygeneration technological solutions. The aim here is to provide policy-makers with a visual tool demonstrating how much potential is still untapped, despite the tremendous benefits of these technologies in terms of fuel savings and reduced CO2 emissions.
