First policy actions on combined heat and power
Published in Maciej M. Sokołowski, European Law on Combined Heat and Power, 2020
Another Community initiative to support energy efficiency was the Thermie programme (Council 1990). Rooted in the philosophy of “no relaxation of efforts to diversify the Community’s energy supply and improve energy efficiency” expressed in a preamble to Council Regulation No 2008/90, the programme began supporting the development of innovative energy technologies because of their economic and social benefits,27 but also environmental welfare. With respect to the latter, energy technology had “a key role to play in meeting the ecological challenge by increasing energy efficiency, developing new and renewable sources and ensuring the clean use of solid fuels” (Council 1990).

In the gasification plant Thermie Energy Farm, one of the three Integrated Gasification Combined Cycle (IGCC) projects selected for funding by the European Union, the sequence of treatment for tar-rich wastewater is: precipitation of sulphur by iron sulphate addition; recovery of sulphur and dust by filtering; disposal of filter cake; stripping off gases dissolved in the water and the major part of the hydrocarbons; partial evaporation of water and usage of condensate as scrubber make-up; discharge of evaporator blowdown to conventional bio-treatment. The low-pollutant-potential material includes salt which is transported to a sanitary landfill. Tar energy is recovered in the combustor by the recycling of the hydrocarbons and the destruction of other stripper gases [116]. This process is possible only for wastes that do not contain many contaminant precursors. The present trend is to develop a system that does not produce a liquid effluent, due to the complexity of the treatment and disposal process . The gasification WTE unit should instead focus attention on the utilisation of renewable biomass coke: this could strongly reduce the impact of global warming and give further value to the important advantages of a reduced amount of residues for final disposal in landfills, and immediate recovery of slags and metals.
