n order to achieve the objectives of Cheap-GSHPs, a multidisciplinary and complementary consortium ...has been built, composed by specialists in dierent disciplines involved (physics, climatology, chemistry, mechanics, engineering, architecture, drilling and GSHE technology). The majority of them have a large and comprehensive experience in the framework of the European Commission (EU) Research Programs and particularly in shallow geothermal systems.

he proposal will focus on one hand on the development of more ecient and safe shallow geothermal ........systems and the reduction of the installation costs. This will be realized first by improving drastically an existing, innovative vertical borehole installation technology and the design of coaxial steel GSHE and second, newly designed basket type GSHE’s with novel installation methodologies will be developed. With a view to improve safety and reduce permitting requirements the improved coaxial GSHE’s will be installed respectively to depths of 40 – 50 meters and the basket type GSHE’s to 15 – 20 meters. This doesn’t prevent however the coaxial GSHE’s to be installed up to depths of 100 – 120 meters.

n the other hand, the proposal will develop a decision support system (DSS) and other design tools ..........covering the geological and drillability aspects, feasibility and economic evaluations based on dierent plant set-up options, selection, design, installation, commissioning and operation of low enthalpy geothermal systems. These tools will be made publicly available on the web at dierent levels for respectively non-expert and expert users, including comprehensive training to lower the market entry threshold.

iven that drilling and GSHE technologies are mature but costly, this holistic approach is included in the ........proposal to bring the overall cost of the total project down, i.e. not just the cost of the GSHE itself but the avoidance of ground response tests, the reduction of the engineering costs for the design of the GSHE and the integration of heat pumps with building heating and cooling systems. Also the use of the novel heat pumps for higher temperatures developed within the project will reduce the costs in the market for retrofitting buildings, in particular for historical ones, when replacement of the high temperature terminals can be avoided. The developments will be demonstrated in six sites with dierent undergrounds and climate conditions, whilst the tools will be applied to several virtual demo cases.

he Consortium is . . . . . .composed by17 p a r t n e r s ( I t a l y , B e l g i u m , G r e e c e , G e r m a n y , F r a n c e , I r e l a n d , R o m a n i a , S p a i n a n d S w i t z e r l a n d ) . Northern, Southern, Western, Eastern and Central EU countries are well balanced so t h a t E u r o p e i s geographically well represented.

GEOLOGICAL MAPPING, CLIMATIC DATA AND ENERGY REQUIREMENTS ll the most relevant aspects that have to be taken into account when designing a new GSHP .....................system are considered, in order to assist users of the Decision Support System (DSS) and explain how the data obtained have been collected and analyzed as shown in WP5. For allowing proper calculations of the DSS robust databases have to be built up. The databases present also representative values that can be easily understood by expert and non-expert users. The resulting map is derived from the generalized geological context (and its associated thermal behavior) with respect to the geological variability of the underground conditions in the Cheap-GSHPs partner countries.

DRILLABILITY AND THERMAL PROPERTIES OF THE UNDERGROUND

he drillability of the geological classes defined in FAU_PAR-MAT-CON was investigated. The result of .......this analysis presents the best drilling technique for each type of underground classes.

thermo-geological database is necessary in order to pick up the right values when sizing a GSHE ..........system. Two dierent types of databases have been built up: one for non-expert users ans one for expert users. The more detailed database has been the result of an activity based on literature analysis as well as on experimental measurements on samples of dierent ground types.

CLIMATIC DATA AND BUILDING ENERGY DEMANDS

climate database has been created to be integrated within the design tool (WP4) developed by the ...........project as well as the DSS.First, data have been collected using the Test Reference Years (TRY) available in ENERGYPLUS software and come TRYs from the database of METEONORM. By comparing the locations and the Köppen-Geiger map of Europe, it results a good definition of most of the climate classes.

ierent types of buildings have been considered: four residential buildings and five non- residential ..........buildings, like as a day care analyze, three administrative buildings and a municipal building were analyzed. Three dierent levels of insulation have been considered for dierent climates. In this way several correlations linking the building area (for residential buildings) or volume (for non-residential buildings) have been found as a function of the Koeppen-Geiger climate and type of building. Moreover standardized hourly profiles have been identified for each month.

HELICOIDAL GSHE AND DRILLING MACHINE DEVELOPMENTS

OBJECTIVES

Development of a drilling machine capable of drilling boreholes with diameters about 350 mm at various depthSimulate, study and develop new GSHE geometries for boreholes with a diameter of 350 mm Simulate, study and develop new GSHE geometries for boreholes with a diameter of 175 mm using a drilling machine which combines ‘Vibrasond’ & ‘easy drill’ drilling technology Identify the best configurations of GSHE and drilling machine

RESULTS

irst, a survey within all partner countries was done to evaluate the recent installation costs and the .......performances of dierent GSHE systems under fixed and various boundary conditions. Then, dierent polyethylene materials and manufacturing processes were tested theoretically and practically to develop a new 15 m long GSHE to fit in boreholes with 350 mm. This easy-to-handle prototype was installed at the drilling machine test site in Molinella, Italy (see picture below) and later on at four dierent demonstration sites of the project. To be able to install this new GSHE in large-dimensioned boreholes, an adequate drilling and installation technique was developed, the so-called ‘enlarged-easy-drill’ technology. This application allows drillings in soft sediments without supporting casing as the drilling rods covers this function. Another issue of this WP was to enlarge the penetrometer technique for boreholes of 175-325 mm to fit with heat basket type GSHEs. This was quite challenging, hence the diameter of the helicoidal GSHE was reduced to fit in boreholes < 100 mm. Although the manufacturing of GSHE with a diameter of 85-90 mm was successful, simulations show that this geometry will have a poor geothermal performance.

CONCLUSION

i thin the WP the combined ...........development of a new helicoidal GSHE together with the advanced ‘enlarged-easy-drill’ technology was accomplished. An easy-to-handle GHSE prototype, with defined and s i m u l a t e d d i m e n s i o n s , w a s successfully installed applying this new drilling methodology. Therefore the achievements of WP2 can tested under real conditions within WP6 at the demonstration sites all over Europe.

OBJECTIVES

CONCLUSION

n this work package, a new rotating and vibrating drilling head is developed. In addition, a high-pressure ....water supply system injects water through a drill bit to lose, further reducing the piling time of steel co-axial heat exchangers. Finally, closure systems ensure the tightness of the heat exchangers. In addition, improvements to the heat exchanger design (diameter, insulated internal tube,..) and new materials are studied to improve thermal energy exchange with the soil. In a test field, the dierent designs and machine developments are tested.

rom the simulations and cost/benefit studies, a stainless steel tube with an enlarged external diameter .......of 76 mm is the best compromise between thermal extraction yield and material cost. A co-extruded inner tube with foam insulation has been realized. Together with the reduced borehole resistance of such GSHE’s, when compared to conventional double-U’s, higher thermal extraction yields in transient operating conditions are expected to be achieved.

Machine ancillaries: vibrating, rotating machine head (d) mounted on existing penetrometer (a), high pressure pump to inject water through the tip of the GSHE. An insulated inner tube (c) prevents the geothermal fluid going up from being cooled down by the colder fluid coming down. In addition, the fluid velocity inside the GSHE reaches turbulent flow conditions, thereby further increasing the energy exchange with the soil.

he modifications to the piling methodology enables the installation of larger diameter heat .........exchangers in more types of undergrounds. The drilling methodology (a) is a variation of the traditional one, designed to optimize the cost/installation for large diameter GSHE’s. The new design uses 1.5 m to 3.0 m long tubes with an external diameter of 76.1 mm. To avoid having to extract the drill bit, a drill bit to lose has been designed with a low cost manufacturing approach. The drilling machine with the new drilling head and the high-pressure pump for water injection was built and will be used in all the demonstration sites to verify its operability in dierent types of underground.The high cost of geothermal plants is due to the cost and duration of the drilling operation. The reduction of drilling time (b) using these new technologies will be one of the steps to achieve the objective of cost reduction of Cheap GSHP project. The increased thermal energy exchange rate of the improved co-axial heat exchangers in transient operating conditions is the other step towards this cost reduction objective since less meters need to be installed for the same power requirement.

It includes a cost/benefit guide to help the selection of the best technology for the heat pump considering the working conditions, that will be included in the selection software. The inventory includes also the environmental impact of the use un refrigerants combined with the heat-pump performance. The WP includes also the study of dierent typical plant configurations in combination with other removable energy technologies like solar thermal, wind, photovoltaic and storage systems. The output include a guideline and cost analysis table to help the optimization of the total plant configuration for dierent application, user priorities and the regional energy prices. This information are included in DSS.

he last result is the design and manufacture of a new generation .......geothermal heat pump with natural refrigerant like CO2, used in trans-critical cycle and low GWP HFO R1234ze. The heat pump is designed to produce high temperature water, up to 80°C with low temperature dierence. The technology applied is the two stage in partial cascade cycle and the ejector to maximize the performance on the evaporator and reduce the investments on the ground source heat exchanger. This new heat pump prototype is installed at Technical Museum Tesla in Zagreb for the air conditioning of the exhibition room

DEMONSTRATION SITES

emo sites completed covered a variety of geological environments, climatic conditions and building ............typologies. They are the UPV campus test site in Valencia, Spain, the bioclimatic oce building of CRES in Pikermi, Greece, the residential eco-house in Putte, Belgium, the REHAU test field in Erlangen, Germany, the Belfield House at University College Dublin, Ireland and the Nikola Tesla museum in Zagreb, Croatia. All demo systems are equipped with real time data logging and online monitoring systems.

ew technologies demonstrated or tested in above sites were ..........innovative drilling rig and equipment, stainless steel 304L coaxial BHEs and piling method, helicoidal BHE and auger/easy drill installation method. At the Zagreb demo site the high temperature HFO/CO2 twin cycle heat pump developed by the project is also demonstrated.

urthermore, the future application of the new technologies .......developed were evaluated by computer simulation of heating and cooling needs at 10 existing buildings, which covered both the building energy use and the energy supply from the earth.

n each case, information about geometry and distribution of spaces (drawings), building data (description or .....thermal properties of opaque and glazing element), description of the use of the occupied spaces (lighting and schedules) and ground properties were collected and a building model was created for its dynamic simulation.

he developed helicoidal BHE oers significant advantages over standard helix in terms of 5-fold more allowable ...........installation depth, pipe stability and easy installation. It also outperforms the single-U in terms of thermal energy output. The developed 76mm 304L stainless steel coaxial BHE with inner insulated pipe showed 10-20% higher geothermal energy yield, 20% cost savings in unstable soil conditions and 15-55% less geothermal energy costs in both heating and cooling operation, compared to single and double U BHEs.The easy drill technology proved eective in cases of unconsolidated soil with unstable borehole walls.The piling method combining thrust, rotation, vibration, water injection, inner shaft, drillbit-to-loose and welding was validated as an eective as drilling method with similar BHE installation rates in consolidated formations and 50% less installation times in unconsolidated sediments.The developed high temperature heat pump provides reliable heating coupled to a high temperature heating system.

It highlights the main context for understanding potential regulatory and legislative quick wins with respect to the deployment of the helicoidal and co-axial heat exchangers developed within the CHEAPs project.

risk assessment support tool for assessing specific aspects of design, installation and operation of ..........the collector in dierent environmental conditions and dierent building types was developed. It demonstrates how the dierent characteristics of buildings and their energy demands can be addressed using the collector, drilling and heat pump technologies developed by the CHEAPS project and also the potential for integration with other technologies within heating and cooling delivery systems. A life cycle cost analysis of the new technologies developed in the CHEAPS project has been developed.

tandards in Europe related to ground source heat ...........pump systems were categorised and ways to introduce the Cheap-GSHPs technology into them were proposed including the application of geothermal technologies in historical buildings and buildings with cultural functions. The analysis of the applicable standards and the development of the CHEAP-GSHPs project technologies highlighted shortcomings in the text of the standards that are perceived as potentially inhibiting the route to market of the innovative technologies. A set of recommendations to CEN and IEC committees that are drafting the standards applicable to the CHEAP-GSHPs technologies were developed. National standards where modifications may be necessary have been identified and recommendations proposed.
