REMINING LOWEX Redevelopment of European Mining Areas into - PowerPoint PPT Presentation

FP6 CONCERTO II REMINING LOWEX Redevelopment of European Mining Areas into Sustainable Communities by Integrating Supply and Demand Side based on Low Exergy Principles Peter Op ‘t Veld – coordinator Cauberg-Huygen Consulting Engineers Maastricht - the Netherlands

Demonstration Four ambitious local communities (Heerlen the Netherlands, Zagorje Slovenia, Czeladz Poland and Bourgas Bulgaria will demonstrate the use of local available low valued renewable energy sources, specifically from water in abandoned mines for heating and cooling of buildings, based on low exergy principles, facilitated by an integrated design of buildings and energy concepts. They will realize 2 sustainable mining communities (Heerlen and Zagorje) with 50 to 100% CO2 reduction and 60% RES compared with standard national practices. The two demonstration sites contain 440 new houses, 57000 m2 non residential new buildings, 84500 m2 non residential existing buildings, and 3 existing prepared buildings to connect with the mine water grid in Heerlen and 6000 m2 new and 2000 m2 existing buildings connected to mine water and 1154 existing houses connected to biomass in Zagorje. Feasibility studies leading to concrete local sustainable energy plans and implementation will be demonstrated in Czeladz, Bourgas, Zagorje and the nearby former mining communities in Heerlen. Dissemination Dissemination takes place in different levels: direct transfer of knowledge to the REMINING communities, use of geothermal energy and heat/cold storage in mines to mining areas in Europe, Russia and Ukraine by involving EURACOM, and the use of local available low valued renewable energy sources in combination with an integrated energy design of buildings for the development of sustainable communities in general, by involving the European Climate Alliance and the LowEx network. Social aspects REMINING has special emphasis of the social aspects in (former) mining communities like unemployment, fuel poverty, poor health conditions resulting in poor quality of life, environmental problems. An integrated sustainable redevelopment will contribute to a high extent in the rehabilitation of this areas and integrating RES from local available sources in combination with RUE in new and existing buildings.

…a bit of history, from Interreg Minewater project to CONCERTO II Remining-lowex • Interreg Mine Water Project: concerning the feasibility and realisation of an energy supply structure based on the use of mine water (with a pilot in Heerlen 2004-2008) • CONCERTO II Remining-Lowex: realisation of communities with an energy supply and energy demand based on the use of low valued energy i.e. mine water but also other RES • Balancing supply and demand, based on the use of RES in “ECO-buildings” • Including the RE sources, infrastructure and buildings

What is REMINING-Lowex about? • Developing sustainable communities in mining and former mining areas • Using water for abandoned mines in combination with other local renewable sources for heating and cooling of buildings • Balancing the local energy demand (buildings) with the local available low valued energy sources (renewables, i.e. mine water, but also other renewables) • Total eligible costs € 39.565.400 • Total funding € 7.226.357 • Duration: five years

What means ‘Lowex’? • Lowex = low exergy • Taking into account the quality of the energy carries for demand and supply • Try to match the quality of energy of the demand with the supply side

Exergy » The valuable part of energy« • Exergy = Energy x Energy- Quality-factor • 100kJ 1 kg water 12 V at 43° C 2.3 Ah • Known method for, e.g. power stations => here application for buildings
