“…Agricultural biomass exploitation is favorable in the Slavonia and Baranja and Vukovar-Srijem Counties, in the eastern part of Croatia where the highest biomass energy potential is estimated through thorough analysis. 5,6 Out of Croatia's total area, around 52 % is agricultural land 7 . Agricultural land refers to land that is arable, under permanent crops, or under permanent meadows and pastures.…”

Biomass availability is one of the key factors for biogas production in the future. The current status and possibilities for utilizing harvest residues (soybean straw, corn stover and sunflower stalk) in Croatia for biogas production is given. In the last few decades, different pretreatment methods have been developed for the degradation of different lignocellulosic biomass, but many of them are environmentally unfriendly and sometimes very expensive. More research and development is necessary in order to find both economically and environmentally friendly pretreatment methods. This paper provides a review on the mechanical, physical, and biological methods used for different lignocellulose material pretreatment. Harvest residues are usually left in the field, but with the improvement of the pretreatment process along with soil protection, they could be used for the production of huge amounts of energy in the future.

a b s t r a c tThis paper provides a solution for managing excess heat production in trigeneration and thus, increases the power plant yearly efficiency. An optimization model for combining biomass trigeneration energy system and pit thermal energy storage has been developed. Furthermore, double piping district heating and cooling network in the residential area without industry consumers was assumed, thus allowing simultaneous flow of the heating and cooling energy. As a consequence, the model is easy to adopt in different regions. Degree-hour method was used for calculation of hourly heating and cooling energy demand. The system covers all the yearly heating and cooling energy needs, while it is assumed that all the electricity can be transferred to the grid due to its renewable origin. The system was modeled in MatlabÓ on hourly basis and hybrid optimization model was used to maximize the net present value (NPV), which was the objective function of the optimization. Economic figures become favorable if the economy-of-scale of both power plant and pit thermal energy storage can be utilized. The results show that the pit thermal energy storage was an excellent option for storing energy and shaving peaks in energy demand. Finally, possible switch from feed-in tariffs to feed-in premiums was assessed and possible subsidy savings have been calculated. The savings are potentially large and can be used for supporting other renewable energy projects.

“…Investment costs, operating and maintaining costs (O&M) for large combustion plants, nuclear plants and RES technologies were obtained from Danish Energy authority [52], Croatian Ministry of Economy [34] and from [17] and [20]. The discount rate of 12% and the economic lifetime of 20 years for wind and solar and 30 years for large conventional plants were used to determinate the annual operating costs of analyzed scenarios [52] and [53]. Total annual operating costs for Resultes on Figure 7 shows that highest annual investments costs of 394 M€ have "RES" scenario while highest fuel costs have "white" scenario.…”

Croatian energy system is currently highly import-dependent and integration of a high share of renewable energy sources needs to be considered. This paper studies eight scenarios; three proposed by the Croatian Energy Strategy, one proposed by the Indicative medium-term development plan of Croatia's Transmission System Operator, and four alternative scenarios that propose extensive construction of hydro, wind and solar power plants in Croatia. Calculations have been conducted in the EnergyPLAN model based on modelled long term energy demand projections in the NeD model, with 2009 as the base year and a scope ranging until the year 2030. Each of the eight proposed scenarios is observed trough different hydrological conditions while analysing import dependency, economic costs and CO2 emissions. After the initial calculations, additional analysis of intensive wind power penetration has been conducted. The Results show that energy systems with a larger share of conventional and nonflexible power plants have more difficulty adjusting to wind power plants production. In case of a high share penetration of wind in a system based upon such power plants, the feasibility of investing in new large combustion plants that will spend most of the time working on minimum capacity is brought into question. INTRODUCTIONGrowing dependency on energy imports, obligation to decrease CO2 emissions, high and unstable energy prices, and increasing age of production facilities are some of the problems European energy systems need to face. In 2010, primary energy import dependency of EU-27 countries amounted to 52.7%, an increase of 22% since 1995, with predictions of reaching 70% in the next 20-30 years [1]. To decrease import dependency, as well as reduce CO2 emissions, European Union is planning increased implementation of renewable energy sources (RES),
