WORK PACKAGE 4 WP4: Advancing low-temperature geothermal energy technologies is aimed at analyzing and assessing geothermal resources in combination with biomass, biogas, solar and heat recovery in several case-study locations in the project partner countries.

WP4 will carry out a technical and economic analysis on the possible integration of low-temperature geothermal energy in combination with other forms of renewable resources in each case-study location. Each integration project will be developed by following the principles and guidelines defined by the strategy document produced in act 3.5. The general objective of this work package is to demonstrate the feasibility of introducing a hybrid system, which allows a more efficient exploitation of available geothermal resources.

ACTIVITIES OF WP4 In the first phase of WP3 are project partners dealing with next activities: -

Activity 4.1: Description of case-study locations: resources, infrastructure and services Activity 4.2: Process modelling of low-temperature geothermal energy Activity 4.3: Economic modelling of low-temperature geothermal energy Activity 4.4: Selection of best integration strategies in each pilot area

Activity 4.1 is aimed at preparing a series of documents that contain relevant information about the casestudy locations. Partners will have to prepare a general description of the area, a description of the infrastructure, a description of the social (public) infrastructure, gather detailed maps that illustrate the current state of affairs and collate all the data in a status quo report. Activity 4.2 is focused on the evaluation of the performance of the studied hybrid installations. The main goal of this activity is to define the productivity, efficiency and capacity for each case-study location. The results of this activity will contain conceptual designs of potential hybrid plants and a detailed analysis of electrical and/or heat power that is attainable. It is foreseen that the following potential projects will be analyzed: -integration of biomass in TopolĹĄica(SI) -integration of biogas in the Euganean hills(I) -integration of solar in Oradea(RO) -integration of CHP in Podravina basin(HR) -integration of biomass in Pest county(HU) -integration of biomass in Palilula municipality(RS) -integration of biomass in Podlog Banja(MK)

Activity 4.3 is structured to provide an assessment of the key economic aspects of the potential plants conceptual design. It wishes to define the essentials of the economic framework, in particular the investment costs (investment funding, construction work, equipment with the installation and unforeseen work),operating and maintenance costs (direct production costs, administrative and general expenditures, sales and distribution expenditures, regular maintenance costs), revenues, energy savings, sources of financing, the indicators of investment and cash flow. A most important factor to consider when producing an economic mode is also the internal rate of return (IRR) factor and a less complicated concept of the return on investment (ROI) factor. This will be used to substantiate the overall great investment opportunity to the stakeholders. Activity 4.4 will evaluate the analyses carried out in 3.2 and 3.4 and select the most appropriate integration strategies that could be replicated across all partner countries. This activity will generate a final technical study and most importantly, an investor’s guide to such applications. These will address the main technical obstacles in the implementation of geothermal technologies and provide economic guidance for various interested stakeholders.


DID YOU KNOW? Most of the current geothermal wells are only about 3 kilometers deep. Apparently, wells as deep as 10 kilometers will make it possible to take advantage of the higher geothermal temperatures at deeper levels beneath the Earth's crust. Wells of that depth are now common in the petroleum industry. Source:

START OF WP5 ACTIVITIES The main goal of WP5 is the development of mapping methodology and a spatial information system, which can be used to determine the most suitable areas for hybrid geothermal implementation. The activity officially began on the 1st of January, 2014. Work has already started on this work package, with act 5.1 which requires the definition of system requirements and functional specification. Within this activity project partners will define the system requirements, functional specifications and data requirements of the geographical information system. The efforts of this work package will rely quite substantially on the work produced in WP3, specifically the compiled data from the user requirement questionnaires. The activity will be coordinated by TESAF but will require full support with providing the data from all project partners.

STAKEHOLDER HEARINGS The project identifies three main target groups or groups of stakeholders. They are the focus of the project, for all of the efforts involved are meant to effect this groups. The stakeholders are identified and divided as follows: RES industries, energy agencies and potential investors Policy and law-makers in Europe (local, regional, national and international) Residents of case study locations and the general public in general

Each group of stakeholders is important in terms of the project goals, but evidently the group that can probably effect the biggest change is the first one, because of the immense volumes of capital at their disposal. This is the reason why this group of stakeholders was/will be directly involved to the project through the communication activities as defined in WP2. The stakeholder hearings have already been organized and completed by LP KSSENA from Slovenia, as well as REAN energy agency from Croatia. The information gathered by these hearings provided great insight on what the expectations of the main target group are, which allows a better understanding on the results that need to be achieved.

The project is co-financed by the EU through SEE Transnational Cooperation Programme.
