Decarbonized Mórahalom – geothermal based sustainable combined green energy pilot project for small settlements

InnoGeo Ltd. in consortium with the Municipality of Mórahalom, REKK Foundation for Regional Energy and Infrastructure Policy Cooperation and MATÁSZSZ Hungarian Association of Hungarian District Heating Providers, submitted a tender for the call for proposals 3.1.3-ZFR-TEFH. The application received a grant on 15 January 2020. The total eligible cost of the project is 414,000EUR, InnoGeo Ltd received 115.000EUR funding.

The general objective of the Decarbonized Mórahalom – geothermal based sustainable, combined green energy pilot project for small settlements is to implement an innovative pilot in the City of Mórahalom, which will serve as a consumer-friendly, secure, environmentally and financially sustainable supply model for settlements with a population of 5-10 thousand.

The objectives of the development are:

1. supplying the significantly increased local heat market demand from geothermal sources;

2. integration of the planned new geothermal system with two other thermal water-based district heating systems operating in the City (“Hunyadi Liget” Geothermal Cascade System and “Norwegian” Geothermal Utility System);

3. diversification of renewable energy production through re-injection of thermal water and expansion of photovoltaic energy production capacity;

4. building a significant technical knowledge base through the implementation of R&D tasks a) utilization of gases generated in thermal wells, b) intelligent control of the integrated district heating system, and c) hydrological, hydrodynamic and geochemical studies of water production and injection;

5. development and replication of a heat service demonstration project for a prosumer partnership suitable for wide replication.

  • Exchange of good practice in the management of geothermal district heating between the donor countries (Iceland, Norway) and the beneficiary countries (Poland, Slovakia, Hungary), that will increase economic as well as environmental and climate benefits for all.    
  • Mathematical modelling of geothermal systems (energy source – heat distribution – end users), in order to identify optimal solutions for the supply of geothermal heat in the beneficiary countries, considering geothermal conditions and heat prices on domestic markets.
  • The focus will be on individual customers in their homes by providing knowledge, experience, and technical solutions to improve the efficiency of geothermal heating. This will be based on data utilisation and the roles of public and individual sustainable solutions. The project will also focus on encouraging customers to modify heating installations in their homes in order to increase their heating efficiency.  


  • Our objectives are a long-term improvement in the efficiency of geothermal operations and a decrease in their environmental footprint: direct contributions to a less carbon-intensive and more energy secure economy in Europe.
  • With EU sources readily available for integrating renewables into DH, our project complements investment measures by reforming the operation of these systems.
  • Our goal is to increase the economics of geothermal DH systems and to support their environmental sustainability simultaneously. We wish to achieve this goal by expanding the knowledge of our staff and by providing innovative solutions to operators.
  • Moving towards low-carbon and energy secure economies necessitates the use of renewables on the one hand, and, maintaining a good status of the environment on the other. Our intervention logic ensures that these objectives can be pursued simultaneously.

Geothermal conversion of district heating in Szeged

Geothermal conversion of district heating in Szeged

The expert team of InnoGeo Ltd takes the lion’s share in the geothermal conversion of district heating in Szeged. In 2018, our company prepared, submitted and won KEHOP tenders for the consortium of SZETAV Ltd (the District Heating Company of Szeged), Geo Hőterm Ltd. and Nemzeti Fejlesztési Programiroda Ltd. for the renewable energy-based conversion of 16 heating circuits. The total value of the 9 projects is 6 billion Euro’s, the support intensity is 50%. The developments supply geothermal energy to the heating plants of SZETÁV Ltd. During the projects, new 1,700 – 2,000 m deep extraction and re-injection thermal wells will be drilled in the Northern, Tarján, Rókus, Downtown, Makkosháza and Odessa districts, which will produce thermal water with an average yield of 80 m3 / h and a temperature of 90°C. This water is not fed into the district heating or domestic hot water network, but is utilized in the boiler rooms via heat exchangers and then returned to the deep water storage layers by means of injection wells. As a result of the projects, nearly 8.8 million m3 of burned natural gas will be replaced annually with 350 thousand GJ of geothermal energy source, cutting SZETÁV’s emissions by 25 thousand tons of CO2 per year, reducing the greenhouse gas load on the city’s air. As a result of the development, the share of renewable energy will be 50% for the total district heating in Szeged, while the air quality and the security of supply will improve. This development is currently the largest geothermal district heating project in Central Europe, and when ready, will be among the largest geothermal district heating systems on the continent.
