The following conclusions and recommendations are made:
The market for natural gas is gradually expanding worldwide while the European gas market is especially a fast growing one. According to various estimations due to strong deficit of own resources the import dependency of the EU countries will raise to some 65-70 % in 2020 that requires provision of additional supply sources and transport chains.
Diversification of NG supply sources and chains, rehabilitation of existing distribution systems, planning of strategic reserves are the main tools for increasing of energy security and guaranteed supply of Europe and transit countries, which are strongly dependent on imported gas.
Prospective supply sources for EU in parallel with traditional suppliers include also Caspian gas reservoirs with proposed 120-140 bcm NG export potential in 2020. The supply of European market from the remote Caspian gas fields requires infrastructure development and introduction of modern NG technologies.
Among the possible Caspian NG supply chains to Europe South Caucasian Pipeline system from Azerbaijan via Georgia, Turkey and possible Greece appears to be more profitable for all, supplier, transit, and consumer parties.
Modern technologies for survey of respective structures, planning and construction of NG storages, first of all underground gas storage facilities in depleted oil and gas fields can provide secured storage of fuel strategic reserves by supplementary commercial impact for mitigation detrimental effect of the supply-demand misbalances and daily/seasonal peak shavings.
The progress in natural gas conversion technologies may offer competitive solutions for decentralized liquid gas production and consumption that may contribute to secure the energy supply and NG cost-effective utilization options in residential sector and industry. Gas liquefaction technologies used to convert natural gas to liquid fuels are under consideration as a competitive option to export gas from remote areas to the international market.
The small scale LNG seems to be economically viable for the transportation to distances about 500 km and supply volume below 2,5 MMscm/d or 600 – 700 kt/y. The small-scale LNG supply could be attractive for countries with significant geographic complexities such as mountains, marshes, impassable forests, etc. In this case LNG could be safely delivered by special tanks or by cars or even by horses. High energy density of LNG creates the point for economic viability of LNG supply projects. Especially it could be interesting for countries, which do not have its own gas resources but have transit pipelines (among them Georgia and Greece).
An advantage in Natural Gas Vehicle (NGV) technologies is leading to lower costs and better performances. Use of NGV reduces fuel costs and satisfies lower emissions mandates (80 – 90% emissions reduction, 10 – 14% less noise level), by 15 – 20% higher capital cost but about 10 % reduction of O&M costs compared with conventional vehicles.
Natural gas is a cleaner fuel than oil or coal, and not as controversial as nuclear energy, it is simple for consumption and convenient for end-users. The natural gas direct burning systems in residential sector are extremely energy efficient and cost-effective comparing with electricity and oil and environmentally friendly than coal and other solid fuels.
New technologies such as NG fuel cells and micro-turbines offer an effective solution to a number of energy challenges, from power generation to environmental degradation in residential, commercial and industrial sectors.
Distributed gas-fired, combined power and heat and cool generation systems enable capture and use of energy that otherwise would be wasted ultimately, result the high efficiency of NG conversation and also significant reduction of the environmental impact.
Key technologies for industrial applications of NG: power generation (Co- or Tri-generation systems), gas co-firing, gas absorption and desiccant systems, chemicals productions provide nowadays highly effective utilization of NG and significant mitigation of environmental impact.
Combined-cycle Gas Turbine (CCGT) systems are new high-effective technologies for producing electricity. CCGT power plant uses waste heat to produce more electricity. The steam produced in the heat recovery units of combined-cycle systems, is directed to a steam turbine for the generation of extra electricity. Efficiency of a combined-cycle gas turbine plant reaches 60%, compared to 30-35% for a conventional fossil fuel fired power plant.
Natural gas utilisation in chemical industry is increasing worldwide due to high efficiency and improved environmental performance of combustion units and conversion technologies, its competitive price, and ability to be converted to liquid fuels and a wide range of chemical products.
Advanced technologies in NG transportation such as: Gas compressors with high efficiency, Gas line inspection modern facilities, Pipe insulation, coating, welding & cathode protection modern tools, Distribution network optimization technique support cost reduction and increased reliability and safety of transportation systems.
Some prospective technologies recommended for implementation and development in NG sector of South Caucasus countries are as follows:
· Usage of medium pressure distribution grids
· Usage of plastic pipes with planned life time 50 years and more
· Implementation of pipeline integrity assessment systems and pipeline repair modern technologies, including No-dig methods of repair, to minimize NG losses in transmission and distribution pipelines
Besides this, special measures can be implemented for improving the energy security of Georgia and other South Caucasus countries. This includes the utilisation of local energy sources, diversification of imported fuels, introduction of modern energy technologies, and accumulation and rational utilization of strategic reserves, which requires further:
· Policy & Legislation Initiatives to Decrease Monopolistic Actions of suppliers and Liberalize Gas Sector, Active support of independent distributors to secure remaining market share (for Georgia - 1/3 of total, including Tbilisi demand)
· On a short-to-medium term basis the main priorities pertaining to the energy security strategies is the diversification of imported natural gas supply
· The dominating elements of the long-term energy policy appropriately reflect the development of renewable energy systems (in Georgia - mainly hydropower projects), in parallel with the implementation of high-efficient integrated gas power cycles (CCGT)
· In order to avoid expected interruptions and obstacles special safety measures should be considered: a) underground gas storage capacity rehabilitation or construction, b) modern small scale technologies for LNG and CNG production and utilization c) newly developed NG combustion technologies – such as Small Scale Thermal and Generation facilities (Decentralized Co- and Tri-Generation units, fuel cells, micro turbines etc).
European countries, including Greece, can act as main supporters for the implementation of modern EU technologies for natural gas transport, storage and utilization technologies that may affect the producer, transit and consumer countries’ energy security and more general the geopolitical development on local, regional and global levels.

When considering the introduction of natural gas fuel into the Israeli energy basket, the Israeli government decided to relate to all the technological and legal aspects of introducing this new fuel type, using the well-established experience of other national entities that went through a similar effort.
· It became very clear that local conditions, such as earthquake spectra, as well as future power and energy development plans, as well as those related to population expansion and density, do influence the choice of standards to be used.
· Local conditions will have to be considered and the chosen code will have to be adapted to the requirements emanating from the imposed constraints. A cooperation of local expert bodies, together with foreign experts to evaluate and review the relevant international as well as the local relevant standards is of essence.
· Strict adherence of the system’s implementing entities to the recommended codes is also very important, so as not to cause delays in the construction and start of operation of this very demanding project

The analyses of the recovery and development order in the gas supply sphere for 10-20 years allow claiming that during that period gas will be the main fuel in Armenia. Nonetheless, to insure the fuel supply security to Armenia it is necessary to diversify gas supply sources, as well as value the usage of the alternative energy sources.
· The preliminary analyses of the results show that the recovery of the central heating gas supply requires the least amount of investments.
· The forecasts for international gas price are given in three versions, afterwards based on the middle scenario the gas price for the final consumer has been assessed considering the necessary investments for the gas supply recovery for the three variants and also the exploitation expenses reduction in the sphere.
· The presented assessments show that that gas price will approach international prices; becoming a heavy burden for the population, unless the economic welfare and incomes of the population increases correspondingly to that period.
· Analysing the legislation in this sphere we may conclude that present legislation in Armenia mostly corresponds to the requirements of free market but the bills that insure the implementation is not sufficiently developed. Furthermore, the incompleteness of the present institutional structure in the gas supply sphere is the main obstacle for the creation of free and competitive market. We make concrete proposals how to fill in the mentioned gaps and to implement institutional improvements in the gas supply sphere, including the principles of functional separation in the sphere and the description of the necessary contractual relationship which will extend commercial relations and will insure sufficient competition.
