EC CONCERTOII project REMINING-Lowex

Presentation for the CONCERTO meeting,November 14, 2011 – Brussels, Belgium

Extracting energy from minewater

Erwin RoijenCauberg-Huygen Consulting Engineers

What is REMINING-Lowex about?

• Developing sustainable communities in mining and former mining areas > transition to clean energy

• Balancing the local energy demand (buildings) with the local available low valued energy sources (renewables, i.e. minewater, but also other renewables)

Update locations – Zagorje, Slovenia

• Completion of – the demo research unit OLEA on the usage of

minewater and other renewables– the community energy monitoring and management

system– the first solar photo voltaic power plant to the public grid– the first charging stations for electric vehicles

• expanded the biomass district heating grid • completed a project documentation for further

expansion of biomass district heating.

Update locations – Zagorje, Slovenia

Research unit OLEA demonstrates: • low exergy direct surface heating with minewater, • building envelope in the standard of passive buildings, • phase change materials for heat and cold storage, • solar thermal collectors for sanitary hot water preparation and support of

heating, • ventilation system with waste air heat recovery with highly efficient

regenerators, • cooling of the building via a ground air heat exchanger, • energy efficient LED electrical light,• solar photo voltaic cells and direct methanol fuel cell for electrical self-

sufficiency, • advanced control systems on the basis of weather forecast and

responsive systems management,• rain water storage,• dry compost toilet with waste water treatment in constructed wetland.

Research unit OLEA

Update locations – Zagorje, Slovenia

Energy management system (community scale):• to measure and control energy flows, • to analyse data and define actions in order to optimize

energy consumption, • to replace out-of-date energy accountancy• educational proposes in order to strengthen a

responsible and environmentally friendly energy management.

Update locations – Zagorje, Slovenia

Solar power plant:• Capacity 13,9 kW• Annual production about 15.000 kWh• Connected to public grid

Update associated community: Czeladz, Poland

• Preparation of retrofitting SRK office• Favourable conditions for connection to minewater• Energy Policy Plan Czeladz in progress now

Update associated community: Bourgas, Bulgaria

• Ideas for buildings to connect• Furniture factory ABV• Several buildings in Cherno More

• Energy Policy Plan Bourgas is planned/in preparation• Studies on several energy configurations completed• Ongoing review of the abandoned coal fields in Bulgaria.

Update work package 2: Research

• Development of a technical guidebook on low exergy solutions

• Development and testing of a high temperature heat pump for DHW:

• University of Ljubljana has completed following research activities:– A coupled model of buildings and district heating system that

was initially used for integration of dispersed sources of renewable heat and now is upgraded with polygeneration (head, cold and electricity). The reports of this work are available.

– A hand book on building physics and low exergy. This handbook is available in Slovenian but will be translated in English.

Update work package 4: Energy exploitation

• Supporting all locations:– Feasibility studies – Financial prognoses and business cases

• General notes and guidelines on energy exploitation

Update work package 5: Legal aspects• A comparative study by EURACOM on the laws relating

to the use of the minewater • Fields of the analysis include:

– European regulation: Competition, states aids regulation, environmental provisions; environmental laws including mining laws; sustainable development regulations (on National and European levels);

– financial supports (European funds (ERDF), national and regional incentive system.

• The legal aspects on minewater and geothermal energy are completed now for France, Hungary, Spain, UK and Slovenia.

• Extended studies of legal aspects concerning minewater use in Silesia and Bourgas.

• General conclusion: there is no specific law relating to minewater as an energy source

Update work package 6: Training• Training material condensed in papers – guidebooks• Training structure:

– General introduction– Elaboration of case(s) as example and framework for knowledge

transfer – Training of decision makers and builders in the communities on

a broad and general level

• Training of:– industry partners and suppliers on a detailed component level– participating researchers on an advanced level– the research community on a EU and international level by

seminars in the frame of conferences– students by elaborated modules for education on universities

Update work package 7: Network and dissemination

• Highlights:• The 8th REMINING meeting has been hosted and organized by

Hunosa, Asturias, Spain.• Contact established with ACOM Russia, ACOM Spain, British

Coal Authority and NCMM, INTERREG IV ReSource project.• Interest for new minewater projects in Belgium (Beringe,

Waterschei, Mons), Germany, Spain (Hunosa) and Russia (Novashatkinsk)

• Events, e.g.: • Polygeneration Conference, March 2011, Tarragona Spain• RETS Conference, 29 March 2011, Sittard, the Netherlands
