Energy is one of the most important inputs that supports Indonesia’s economy. The government utilises coal and oil as the main sources for power plants energy mix. However, the utilization of fossil fuel energy has been proven to pose negative impacts on the environment such as, increasing carbon dioxide emission which leads to global warming. This study analyses investment policy on increasing electricity production of geothermal power plants as well as substitution of fossil energy to geothermal energy using Computable General Equilibrium (CGE) Model and Indonesia’s data of Social Accounting Matrix 2008. The result shows that when investment on the substitution of energy from fossil to renewable energy takes place, economic growth will increase and carbon dioxide emission will reduce significantly.

Spain and Portugal are highly dependent on energy from abroad, importing more than 70% of all the energy they consume. This high energy dependence could involve important effects on the level and stability of their electricity prices as a half the gross electricity generated in both countries came from power stations using imported combustible fuels (such as natural gas, coal and oil). In general, changes in the prices of these fossil fuels can directly affect household electricity prices, since generation costs are likely to be transmitted through to the wholesale electricity market. Moreover, in the framework of the European Union Emission Trading System, electricity production technologies tend to incorporate their costs of carbon dioxide emission allowances in sale offers with the consequent increase of the electricity prices. The objective of this paper is to analyze the influence of fossil fuel costs and prices of carbon dioxide emission allowances in the EU on the Spanish and Portuguese electricity prices. With this aim, a maximum entropy econometric approach is used. The obtained results indicate that not only the price of imported gas are very important in explaining Spanish and Portuguese electricity prices but also the price of carbon dioxide emission allowances in the EU.

Negative Impacts

Electricity is one of the strategic commodities in Indonesia. The Increasing of electrical price (so called TDL stand for Tarif Dasar Listrik) administered by the government will be negative impact on Indonesian economic performance. Based on this research analysis, a rise of TDL will have negative impact on macro and sectoral economic performance. This study aims to analyze the effects of a rise of TDL and policy responses to minimize its negative impacts on Indonesian economic performance. The data which is used in this research areInput Output Table, Social Accounting Matrix (SAM) and SUSENAS data. Sources of data obtained from Board Central of Statistics. The analysis using Computable General Equilibrium (CGE) model is called INDOTDL CGE model. The simulation results show that a rise of TDL will have negative impact oneconomic growth, household consumption, export, employment and sectoral demand.  This study also shows that an increase of  efficiency in electricity sector by 10 percent is expected to decrease the electrical price.  In addition, a rise of  TDL which is followed by an increase of efficiency or decrease of value added tax (VAT) policy in all sector have positive impact on macro and sectoral economic performance on Indonesian. The most effective policy to economic improvementis to increase efficiency of electricity sector, so TDL doesn’t need to be increased.Keywords : TDL, CGE, Efficiency, VAT, Economic Performance

Burning fossil fuel like coal in power plants released carbon dioxide that had been absorbed millions of years ago. Unfortunately, excessive carbon dioxide emission had led to global warming. Malaysia, as one of the major exporters of palm oil, has abundant oil palm mill residues that could be converted into value-added product like biomass fuel briquettes. Fuel briquette with palm kernel shell and palm mesocarp fibre as its main ingredients showed satisfactory fuel characteristics and mechanical properties as a pure biomass fuel briquette. The effects of adding some coal of higher calorific value to the satisfactory biomass fuel briquette were focused in this study. Various coal-biomass fuel blends were used, ranging from 0wt% coal to 50wt% coal. The fuel properties and mechanical properties of pure biomass briquette and briquettes with different amount of coal added were compared experimentally. From the fuel properties tests, it was found that as the coal content in the briquette was increased, the carbon content and calorific value increased. Mechanical property tests on the fuel briquettes showed a mixture of results, with some favored higher portion of coal in the briquette for better handling, transport and storage properties while some favored greater amount of biomass.

Abstract Against the background of a growing deployment of renewable electricity production, like wind and solar, the demand for energy storage will only increase. One of the most promising ways to cover the medium to long-term storage is to use the excess electricity to produce hydrogen via electrolysis. In a modern energy grid, filled with intermittent power sources and ever-increasing problems to construct large power plants in densely populated areas, a network of Decentralised Energy Systems (DES) seems more logical. Therefore, the importance of research into the design of a small to medium-sized hydrogen fuelled micro Gas Turbine (mGT) unit for efficient, local heat and electricity production becomes apparent. To be able to compete with Reciprocating Internal Combustion Engines (RICEs), the mGT needs to reach 40% electrical efficiency. To do so, there are two main challenges; the design of an ultra-low NOX hydrogen combustor and a high Turbine Inlet Temperature (TIT) radial turbine. In this paper, we report on the progress of our work towards that goal. First, an improvement of the initial single-nozzle swirler (swozzle) combustor geometry was abandoned in favour of a full CFD (steady RANS) design and optimisation of a micromix type combustion chamber, due to its advantages towards NOx-emission reduction. Second, a full CFD design and optimisation of the compressor and turbine is performed. The improved micromix combustor geometry resulted in a NOx level reduction of more than 1 order of magnitude compared to our previous swozzle design (from 1400 ppm to 250 ppm). Moreover, several design parameters, such as the position and diameter of the hydrogen injection nozzle and the Air Guiding Panel (AGP) height, have been optimized to improve the flow patterns. Next to the combustion chamber, CFD simulations of the compressor and turbine matched the 1D performance calculations and reached the desired performance goals. A CFD analysis of the impact of the tip gap and exhaust diffuser cone angle led to a choice of these parameters that improved the compressor and turbine performance with a limited loss in efficiency.
