Danube Region Leading Geothermal Energy –DARLINGe

Danube Region Leading Geothermal Energy –DARLINGe

Danube Region Leading Geothermal Energy –DARLINGe (DTP1-1-099-3.2): 10 ERDF and 5 IPA partners representing geological surveys, university, industry, regional energy and development agencies, ministry and municipality from 6 countries worked together to improve energy security and efficiency in the Danube Region by promoting sustainable utilization of the existing, however still largely untapped deep geothermal resources in the heating sector. A lead research project partner, InnoGeo was responsible for all activities at the Hungarian a pilot sites of the project with Dr. Medgyes being the lead researcher responsible for coordinating all activities in the Hungarian-Romanian-Serbian target area and providing their expertise to the R&D work-packages of the 2.5M Euro’s budget project.

Development of inclined, surface-increased well design and operation technology in a deep geothermal extraction-injection system installed on a porous reservoir

In the project GINOP-2.1.1-15.2016-00970, Development of inclined, surface-increased well design and operation technology in a deep geothermal extraction-injection system installed on a porous reservoir, InnoGeo Ltd carried out geological, hydrogeological data collection on the parameters of production and porous injection systems, hydrodynamic simulation covering the entire reservoir, designation of an experimental doublet site, 5-well pump test, investigation of the effects of hydrocarbon mining in the Upper Pannonian porous hydrodynamic characteristics, area-wide regional heat transport simulation, hydrodynamic modeling of expected injectability differences between vertical and skewed well design, performance of full-range full geophysical tests, multi-stage load well test on the well pair, three k performing a well-interfering well load test with different yields, two-phase (I. oblique well-pair before installation, II. oblique well-pair post-installation) regional pulsation, load well interference study involving a total of 6 extraction and re-injection wells.

Construction of the New-Szeged geothermal cascaded system in Szeged (KEOP-4.10.0/B/12-2013-0034)

Construction of the New-Szeged geothermal cascaded system in Szeged (KEOP-4.10.0/B/12-2013-0034)

In the fall of 2013, another lighthouse investment began in Szeged when the conversion of 11, mostly university- and city-owned institutions to environmentally friendly, geothermal energy heating started with the construction of a cascaded system commonly referred to as the “clinical thermal circuit”. The construction and subsequent operation of the system is carried out by Geothermal Service Ltd., which sells the extracted geothermal energy to the University of Szeged and the other end-users.

The heat market survey, hydrogeological planning, cost-benefit analysis as well as the successful application process for EU funding were carried out by InnoGeo Kft.

The project supplies the New-Szeged buildings of the University of Szeged, 4 municipal buildings and 2 state-owned buildings, with geothermal energy. The project included the construction of 3 thermal wells (1 production and 2 injection wells), 3.1 km district heating pipelines and 12 heating centres, equipped with a state-of-the-art optical network and SCADA control and display system. The 4.5 MW renewable heat capacity cascaded system produces about 37,000 GJ of heat per year, thus substituting 1.3 million m3 of natural gas per year. In addition, it will achieve an emission-reduction of 2,343 tonnes CO2 / year, or, 70,000 tonnes of CO2 over the planned 30-year service life. The energy cost savings in the relevant university and city institutions are HUF 60 million (170,000 EUR) per year. The total net cost of the construction of the system was HUF 1,254,250,000 (3.5M EUR). The investor Geothermal Service Ltd. received HUF 596,646,725 (1.7M EUR) EU funding.

Construction of the downtown geothermal cascaded system in Szeged (KEOP-4.10.0/B/12-2013-0035)

Construction of the downtown geothermal cascaded system in Szeged (KEOP-4.10.0/B/12-2013-0035)

In the spring of 2013, a lighthouse investment began in downtown Szeged when the conversion of 25, mostly university- and city-owned institutions to environmentally friendly, geothermal energy heating started with the construction of a cascaded system commonly referred to as the “university thermal circuit”. The construction and subsequent operation of the system is carried out by Szeged-based Geothermal Service Ltd., which sells the extracted geothermal energy to the University of Szeged and the other end-users.

The heat market survey, hydrogeological planning, cost-benefit analysis as well as the successful application process for EU funding were carried out by InnoGeo Kft.

The project supplies the downtown buildings of the University of Szeged (the largest natural gas user of the city), the city library and a newly built hotel, with geothermal energy. The project included the construction of 3 thermal wells (1 production and 2 injection wells), 3.5 km district heating pipelines and 25 heating centres, equipped with a state-of-the-art optical network and SCADA control and display system. The 4.4 MW renewable heat capacity cascaded system produces about 55,000 GJ of heat per year, thus substituting 1.8 million m3 of natural gas per year. In addition, it will achieve an emission-reduction of 3,633 tonnes CO2 / year, or, 100,000 tonnes of CO2 over the planned 30-year service life. The energy cost savings in the relevant university and city institutions are HUF 76 million (200,000 EUR) per year. The total net cost of the construction of the system was HUF 2,001,500,000 (5.6M EUR). The investor Geothermal Service Ltd. received HUF 996,747,000 (2.8M EUR) EU funding.

ENERGY EFFICIENCY MODERNIZATION OF BUDAPEST, PESTI ÚTI TESCO DEPARTMENT USING GROUND HEAT AND MICROGAS TURBINE (CONSTRUCTION)

ENERGY EFFICIENCY MODERNIZATION OF BUDAPEST, PESTI ÚTI TESCO DEPARTMENT USING GROUND HEAT AND MICROGAS TURBINE (CONSTRUCTION)

InnoGeo Ltd participated in the renewable energy based building engineering reconstruction of the Tesco Store on Pesti út (Budapest). The Energy Efficient System Solution Using Geothermal Heat and Microgas project was entered in the 2010 year competition of the Hungarian Innovation Association. The application (carried out in cooperation with TESCO Global Áruházak Zrt and Regale Energy Zrt) received honourable mention.
