International Geothermal Association (IGA) and Geothermal Implementing Agreement (GIA) under Committee on Energy Research & Technology (CERT) of International Energy Agency (IEA) are the two major international organizations leading geothermal research, development and deployment (RD&D). IGA has been established in 1988 by geothermal societies in Europe and America and presently consists of 23 affiliated societies. Current number of members of IGA reaches 2,000 from 65 countries and its most important activity may be to organize the World Geothermal Congress (WGC) every five years. IEA-GIA has been established in 1993 and its executive committee (ExCo) consists of 11 countries, 1 organization (EC) and 3 sponsor companies. Korea became a member of ExCo on September 2005 through Korea Institute of Geoscience & Mineral Resources (KIGAM) as representative. KIGAM is also actively participating in Direct Use Annex through a task leader of several tasks.

Concentrated Solar Power (CSP) is a renewable energy to generate electricity by using solar thermal energy as a heat source to drive turbines or engines for thermodynamic cycles. This paper introduces ongoing projects in SolarPACES(Solar Power and Chemical Energy systems) under the REWP(Renewable Energy Working Party) in the IEA(International Energy Agency). Then, the current status of international CSP markets and domestic activities is summarized. Finally, the CSP outlook by IEA and the key technological challenges to be overcome for its realization are presented.

SolarPACES(Solar Power and Chemical Energy systems) is an international organization under the REWP(Renewable Energy Working Party)in the IEA(International Energy Agency) and focuses on the technology development and market expansion of CSP(Concentrating Solar Power). Seventeen countries including Rep. of Korea participate in the ExCo(Executive Committee) of SolarPACES. The ExCo meeting helds two times in a year and the second ExCo meeting opens in company with the five Task meetings. Rep. of Korea takes part in the Task-1officially. The 81th ExCo and Task meetings were held during September 18 and 19 in Spain with SolarPACES conference which also continued in succession to September 23 in this year. This paper introduces the activities which have been under progressed in the Task-1 and Task-3based on this time attendance of the meeting. In accordance with the expansion of CSP market and technology development, the needs for the standardization and project status underway in the world are increasing. Therefore, build an international project database and standard of the CSP technology are the main activities in the Task-1 and the standardization is also connected with the Task-3. In addition, to increase the reliability of the new technology of CSP and to reduce the concern of investors, the Task-1 is making guidelines for CSP performance prediction which can provide medium quality calculated performance data of PTC(Parabolic Trough Concentrator) type technology widely used and occupies over 90% CSP market.

Within the IEA (International Energy Agency) PVPS (Photovoltaic Power System) Programme Task 15, 'Enabling Framework for the Acceleration of BIPV,' a round-robin action focusing on the performance of vertical BIPV elements as a facade in different climatic environments was performed. The performance of identical (both, in construction and bill of materials (BOM)) glass-to-glass c-Si BIPV elements was monitored at seven outdoor test sites in 6 different countries in Europe and Asia. In this work, the comprehensive results of the electrical and corresponding meteorological data will be presented and discussed. The monitored data were merged, processed, and filtered for further analysis. The analysis includes the chracteristics of the module temperatures and the in-plane irradiation at the outdoor test locations, mean daily PR per test module, time series of mean daily performance ratio coefficients, and monthly yield.

SolarPACES is an international cooperative network bringing together teams of national exports from around the world to focus on the development and marketing of concentrating solar power systems (also known as solar thermal power systems). It is one of a number of collaborative programs, called Implementing Agreements, managed under the umbrella of the International Energy Agency to help find solutions to worldwide energy problems. Technology development is at the core of the work of SolarPACES. Member countries work together on activities aimed at solving the wide range of technical problems associated with commercialization of concentrating solar technology, including large-scale system tests and the development of advanced technologies, components, instrumentation, and systems analysis techniques. In addition to technology development, market development and building of awareness of the potential of concentrating solar technologies are key elements of the SolarPACES program The Implementing Agreement specifies broad "Tasks," or thematic areas of work SolarPACES currently has three ongoing tasks, focusing on concentrating solar electric power systems (Task I), solar chemistry research (Task II), and solar technology and applications (Task III). An Operating Agent, nominated by the ExCo, is responsible for overseeing the work of each task Each task maintains a detailed program of work that defines all task activities, including their objectives, participants, plans, and budgets. In addition to technical reports of the activities and their participants, accomplishments and progress are summarized in the SolarPACES annual report. Many SolarPACES activities involve close cooperation among member countries (either through sharing of task activities or, occasionally, cost-sharing), although some cooperation is limited to sharing of information and results with other participants. In this paper, structure, works, and members of SolarPACES and Korean activies in the SolarPACES are introduced.

The application of an oxy-combustion circulating fluidized bed combustor (Oxy-CFBC) for low grade coals has recently developed in the world to meet the continuous increase of energy demand and to achieve the reduction of greenhouse gases. Since demo plants for Oxy-CFBC have been developed, the combustion properties of Oxy-CFBC in various operation conditions, such as gas flow rates, combustion temperature, fuel, and so on, should be investigated to develop design criteria for a commercial Oxy-CFBC. In this study, a computational simulation tool for Oxy-CFBC was developed on the basis of the IEA-CFBC (International Energy Agency Circulating Fluidized Bed Combustor) model. Simulation was performed under various conditions such as reaction temperature ($800^{\circ}C{\sim}900^{\circ}C$), oxygen contents (21%~41%), coal feeding rate, Ca/S mole ratio (1.5~4.0), and so on. Simulation results show that the combustion furnace temperature is higher in oxy 1 than air fired. However, the temperature gradient tended to decrease with increasing oxy mixing percent. In case of $SO_x$, the higher the Ca/S mole ratio and oxy mixing percent, the higher the desulfurization efficiency.

The purposes of this study is to develop a domestic MARKAL(MARKet ALlocation) model with construction of database system to find the technology mix for the electricity generation market in Korea. The MARKAL model is officially used for national energy system optimization in the International Energy Agency(IEA), and the role is becoming more important in relation to analyze the greenhouse gas mitigation potential and to evaluate the technologies. Four scenarios specially emphasized on the greenhouse gas reduction and technology mix of electric generation were applied, each of them covering the analysis periods between 2004 and 2040.
