Project of the Croatian solar house as an energy development strategy of Croatia in the field of households

Zvonimir Glasnović Natko Urli U.V. Desnica Božidar Etlinger Mladen Sesartić

The project Croatian Solar House (CSH) has a strategic value for the Croatian society and state due to its wide reaching solutions of the energy and environment problem in Croatia, which are technically feasible and economically practical. The goals of the CSH project are in total accordance with the strategic decisions of the EU toward the sustainable development on the way of the energy consumption rationalization, the essential ratio raiseof the pure renewable sources, as well by the CO2 and other pollutants reduction. Unlike the non-ambitious energy strategy, which could lead to the 70% energy import dependency of Croatia by the year 2030, the CSH project, through a wide range of planned constructive actions, demonstrates and proves the possibility of totally different approaches and strategies. Through the proposed solutions can be achieved the goals of the sustainable development atatining and an energy dependency as well as the CO2 emission reduction near the Kyoto protocol.

Optimiranje fotonaponskih sustava primijenjenih u navodnjavanju

Zvonimir Glasnović

Recent methods for the determination of nominal electric power of photovoltaic (PV) water pumping systems for irrigation have been based on graphic tools of manufacturers and/or proper calculations, whose basic incoming parameters are: hydraulic energy demand, monthly average daily solar irradiation and characteristics of PV water pumping system. However, in this procedure has been separately considered the demand for hydraulic energy and possibilities of its production from the available solar energy with the PV water pumping system. Further, it have not been considered the dynamic characteristics of boreholes as well as the water storage in the soil during the season of irrigation. All of this has resulted in an unsystematic and therefore rather imprecise procedure of the system sizing, whereby it has been often overrated, which consequently reflected the higher investment and eventual economic sustainability of those systems. Through this dissertation was given the scientific procedure of the sizing of the optimal PV water pumping system for irrigation. In this sense, it is systematically analysed the subject problem and completely considered all the relevant system elements and their characteristics, i.e. characteristics of PV water pumping system, water supply from boreholes, local climate, soil, crops and irrigation methods. The objective function is the minimization of the maximal nominal electric power of PV generator (MIN-MAX procedure) and the hybrid simulation-optimization model was applied, wherein for the optimization was used the dynamic programming, while the constraints are defined by the simulation model. For all that, the system is viewed without the water and/or energy accumulation, further the irrigation system by trickle distribution method and for the PV water pumping systems of the second generation submersible motor-pump subsystem. For the purpose of the verification of the model optimization and reaching appropriate researching results, as well as gaining the knowledge of the applying possibilities of PV water pumping systems for irrigation in Croatia, were chosen the locations in Osijek and Split areas. By variation of different parameters was shown that this model successfully takes into consideration all characteristic values and their relations in the integrated system, whereby through this model could be, in satisfactory way, determinated the optimal value of PV water pumping system for irrigation.

Introduction of PV Energy Into an Existing HEP

IEEE Transactions on Energy Conversion (2011)

Jure Margeta Zvonimir Glasnović

This paper analyzes a possibility of upgrading hydroelectric plant (HEP) with solar photovoltaic (PV) generator. The main objective of this solution is maximization of green energy production in accordance with local and existing HEP framework. The example of HEP Zavrelje/Dubrovnik in Croatia was used as a paradigm of such exploitation of RES. The results of the analysis confirm that the proposed solution of hybrid work PV-HEP system is natural, realistic, and very promising. By hybridization of these two main natural energy sources, the characteristics of both energy sources are enhanced. The application of such hybrid systems would increase the share of green energy in the electric power systems and thus reduce the CO $_2$ emission from energy sources.

The role of Croatian agency for energy efficiency and renewable energy sources

Energy & Environment (2006)

Zvonimir Glasnović Željko Tomšić Mladen Sesartić

This paper analyses and situates the role of the Agency for energy efficiency and renewable energy sources (Agency). In this sense the paper examines the coordination of the Agency's objectives of national programs for energy efficiency and renewable sources with the required financial support for their realization. Considering that Croatia spends a relatively high percentage of its Gross Domestic Product for the importation of quality energy sources, it is evident that it is necessary to undertake a series of measures for more efficient energy uses and to commence production from renewable sources. In Croatia a potential for more efficient uses of energy exists in all three main sectors of energy consumption, i.e. industry, transport and household. The paper also discusses the administrative aspect of the Agency and its aims and objectives, namely appropriate projects and initiatives. The Agency's organizational structure is also dealt with, in which local Agencies would play a particular role. It is understood that the relationship will be based on a partnership and that classical subordination will be avoided. This means that a cooperative working relationship will be undertaken in the sense of encouragement and support of local initiatives and projects in order to achieve the realization of common objectives.

Humanity Can Still Stop Climate Change by Implementing a New International Climate Agreement and Applying Radical New Technology

Energies (2020)

Zvonimir Glasnović Karmen Margeta Nataša Zabukovec Logar

There is a broad consensus worldwide that anthropogenic climate change is a scientific fact. Likewise, the fact is that the UN’s efforts to address climate change over the last 28 years have not been successful enough. It is evident that the global average temperature is on the rise (1.1 °C above pre-industrial levels in 2019). A particular concern comes from the fact that the Paris Agreement on keeping increases in the global average temperature to below +2 °C is an unenforceable ambition, since the focus is more on consequences than causes. In addition, economic policies regarding global taxes, as well as adaptation and mitigation measures, are questionable, as there is no evidence that changes in the climate system will proceed at the same rate in the coming years. This paper proposes an engineering approach that considers all relevant aspects of the climate change problem and proposes a new policy, named the “Climate New Deal”. It deals with: (i) Reorientation from a high-carbon economy to a green economy; (ii) The intensive use of radically new technology, e.g., “Seawater Steam Engine” technology for the simultaneous production of thermal and electric energy and drinking water; and (iii) The intensive use of energy efficient technologies and RES technologies, especially in transport.

Seawater Steam Engine as a prime mover for third industrial revolution

Zvonimir Glasnović Karmen Margeta

Radical new technology Seawater Steam Engine presented in this book is a scientific and technological breakthrough with the hopes of stopping climate change. New technology can simultaneously produce energy and drinking water, using only 3 natural forces: Renewable energy sources (RES), Seawater and Gravity. In the next 15-30 years with this technology it will be possible to produce 24,441 TWh of energy and 244 km3 of drinkable water per year, which are amounts that can satisfy mankind’s needs for energy and drinkable water and save up to 20 Gt of CO2. Seawater Steam Engine technology has an extremely high potential for further development and could in fact become the ‘prime mover’ of third, and last, industrial revolution, which essentially becomes a synonym for realization of sustainable communities.
