The intention of the paper was to research and stress the possibilities for Energy Strategy implementation and practical realization of planned energy infrastructure due to improvement of security of energy supply and competitiveness of the Croatian energy system. Mogućnosti implementacije Strategije energetskog razvitka Republike Hrvatske Izvornoznanstveni članak Ovaj članak nas upoznaje sa strategijom energetskog razvoja Republike Hrvatske uz prikaz neposredne potrošnje energije kao i planirani razvoj energetske infrastrukture. Namjera članka je ukazati na mogućnosti implementacije Strategije energetskog razvitka kao i praktična realizacija planirane energetske infrastrukture radi povećanja sigurnosti opskrbe energijom te povećanja konkurentnosti energetskog sustava Republike Hrvatske.

Therefore, the issues in the energy sectors of analyzed countries have become more pressing. The global economic and financial crises significantly decreased the amount of western liquid capital. Crisis also exposed the region’s vulnerabilities and increased investment risks. Analyzed countries don’t have significant economic potential for funding large scale energy projects. Therefore funding became a key obstacle to energy investments. So, the policy main problem became how to finance major energy projects proposed in strategies. On the other hand, current economic depression influenced governments resulting with renewable energy initiatives taken even more seriously. The renewable energy sector has a great potential for industrial growth. The developed EU countries push towards green economy therefore EU RES targets became more important. Almost 80 billion EUR in investments is needed for achieving RES targets in the analyzed countries including Croatia. Comparing with conventional energy sources renewables are not competitive and there will be challenging to attract required capital for project investments. Natural gas transport disputes between Russia and Ukraine exposed energy vulnerability to disruption, led to restrictions on natural gas consumption and resulted with the issue of energy dependence as a top priority in most analyzed countries’ energy policy including Croatia.

Besides the direct emissions of some GHG, the petroleum industry is also characterised with high energy intensity usually followed by emissions of adverse gases, especially at old facilities, and also the products with high emission potential. Being the global industry and one of the major players on global market, the petroleum industry is also subjected to global regulatory provisions regarding GHG emissions. In this chapter, the impact of global climate change on the petroleum industry is discussed. The emissions from the petroleum industry are analysed with a special focus on greenhouse gases that occur in petroleum industry activities and types and sources of emissions from the petroleum industry activities. In addition, recommendations for estimation, monitoring, and reductions of GHG emissions from the petroleum industry are given.

Treci paket energetskih propisa Europske unije donosi niz obveza energetskom sektoru Republike Hrvatske među kojima se isticu uspostava energetskog tržista, reorganizacija energetskog regulatora te stvarno otvaranje tržista uz slobodan pristup trece strane i transfer energije. Također, u radu je navedena obveza usvajanja Programa provedbe Strategije energetskog razvitka Republike Hrvatske iz 2009. godine ciji su temeljni ciljevi sigurnost energetske opskrbe, konkurentnost energetskog sustava i održivost energetskog razvitka. Prikazani su postojeci i planirani pravci opskrbe naftom i prirodnim plinom u jugoistocnoj Europi, konkurentni infrastrukturni energetski projekti te je dan prikaz potencijala nekonvencionalnih ležista ugljikovodika u Europi.

Iako je nafta jos uvijek dominantni energent u ukupnoj svjetskoj potrosnji, sto se nece promijeniti u slijedecih nekoliko desetljeca, predviđa se da ce potrosnja prirodnog plina do 2050. g. porasti, sa sadasnjih 23 %, na gotovo 50 %. S porastom svjetske potražnje prirodnog plina javlja se potreba razvoja postojecih nacina transporta plina, ali i razvoj novih tehnologija, koje ce omoguciti ucinkovito i ekonomski prihvatljivo transportiranje plina na male i velike udaljenosti. Jedno od spomenutih tehnoloskih rjesenja je i transport prirodnog plina pri visokom tlaku u obliku stlacenog prirodnog plina (Compressed Natural Gas, CNG). CNG tehnologija transporta prirodnog plina je ekonomski isplativa za transport prirodnog plina na manje udaljenosti od manjih ili starih (djelomicno iscrpljenih) plinskih polja s maksimalnom proizvodnjom do 3×106 m3/d. Transport prirodnog plina morem u obliku CNG- a obavlja se specijalno prilagođenim brodovima. Kako je Hrvatska zemlja koja ima razvijenu brodogradnju, potrebe za transportom prirodnog plina u obliku CNG- a predstavljaju mogucnosti buduceg razvoja brodogradnje u Hrvatskoj. Iako CNG tehnologija nije nova, trenutno ni jedan projekt transporta prirodnog plina u obliku CNG- a morem nije u komercijalnoj upotrebi, no obzirom na njene brojne prednosti može se zakljuciti da je ova tehnologija na pragu komercijalne upotrebe.

Today the high share of responsibility for adverse environmental impact due to greenhouse gas (GHG) emissions lies on industry and energy sector. Petroleum industry is GHG emissions intensive industry. Beside direct CO2 and CH4 emissions during hydrocarbons production, petroleum industry is also characterized with high- energy intensity and final products of high emission potentials. Principles of environmental protection became embedded in petroleum industry activities for more than half of a century. Environmental management techniques have been successfully integrated into all segments of petroleum upstream operational procedures and activities, from exploration work, through drilling operations, field development, production of oil or natural gas and ending by field abatement. In 1996 the Republic of Croatia ratified UNFCCC which was followed by ratification of several other international settlements that will affect national energy system, among which the most important is the Kyoto Protocol. INA Inc. is the Croatian national petroleum company. Among INA’ s capacities the biggest GHG emitters are gas- condensate field Molve and oil refineries in Rijeka and Sisak. The Molve field has extremely unfavorable reservoir conditions with high pressure, high temperature and significant share of CO2 and other adverse gases. Besides facing the same problems as other national petroleum industries due to new high ecological standards, Croatian petroleum industry is also faced with increasing international directives for adoption of international environmental regulations. Since Croatian petroleum industry will significantly be affected by greenhouse gases emission stabilization, INA started to take steps towards limiting greenhouse gas emissions from its own operations through the development and implementation of cleaner and energy efficient technologies. In this paper these new technologies for efficient GHG management in Croatian petroleum industry will be described.
