Greenhouse Gas Abatement Cost of Clinker Substitution in Thailand’s Cement Industry

This research study about the abatement cost of CO2 reduction by using fly ash as a clinker substitute in Thailand cement industry. And also present the sensitivity analysis about the factors that affect the abatement cost. The proportion of quantity to use fly ash as a clinker is equal to 1: 1 ton, therefor will calculate at 1 ton of clinker which make the quantity of mitigated CO2 in this research is equal to 0.825 tonCO2/year. Use the information in year 2015 to analyze, such as the exchange rate, fly ash price and transportation rate. And use average distance of fly ash transportation from the power plant to cement plant to calculate. From the information, the approach to reduce CO2 by this method is without additional investment. Because fly ash is small it can be mixed with clinker before grinding step of the original process. The CO2 abatement cost of this method is equal to -106.16 USD/tonCO2, which is regarded as a worthwhile investment. The factor is the most affect to mitigation cost is transportation rates. The transportation current rate is 0.092 USD/ton/km but if it increases, the abatement cost will also increase accordingly. Moreover we also calculate the maximum distance to decide on the purchase of fly ash from each of power plant.

Potential of Fly Ash Utilization for the Clinker Substitution in Cement Industry in Thailand

The main objective of this article is to forecast CO2 mitigation from clinker production and to evaluate Fly Ash potential, used Clinker Substitution for CO2 mitigation in cement industry between years 2015-2036 in Thailand following information of the Thailands power developments plan (PDP2015). PDP2015 forecasts the potential of fly ash in the year 2036 which is estimated at 3.94 M ton and 48.76 M TonCO2 of CO2 emission from 58.01 M Ton of clinker production process. The methodology which is used for potential evaluation of fly ash and amount of CO2 can evaluate from Mae Moh power plant technology. 1 MW can occur 952.3427 Ton and amount of CO2 emission from utilizing is 0.825 TonCO2/TonneCli which is a default value of CSI (Cement Sustainability Initiative).The three different scenarios are used to analysis in this study. The condition of Business As Usual (BAU) scenario is the need of technology, used in 2015 as a base case. The full potential scenario (FP) is represent to the 100% fly ash using. The final scenario is called Zoning scenario (Z scenario) which consists of price rate (270 THB per Ton) and transportation rate (6 THB per kilometer of fly ash). From the result, in 2036 fly ash occur 7.46 M Ton that can mitigate CO2 volume up to 6.15 M TonCO2

Household electricity demand forecast and energy savings potential for Vientiane, Lao PDR

This paper uses the survey data on household electricity demand from five districts of Vientiane, Lao PDR, for the demand projection up to 2030 using the end-use model. The scenario analysis is used to verify the potential of an energy-saving program by alternating selected appliances with more energy-efficient ones following the labelling standard of Thailand. The demographic structure of electrified households and the energy efficiency of electric appliances are considered as the dominant factors affecting electricity demand. Under the base-case scenario, the total electricity demand of Vientiane increased from 593 GWh in 2013 to 965 GWh in 2030. In the energy efficiency scenario, it is revealed that the appliance standard enhancement program can save total electricity demand in 2030 by 147 GWh (−15.2%), where 117 GWh (−12.1%) of which is contributed by the air conditioner and 30 GWh (−3.1%) by the lighting equipment.

A Study on Energy-Related GHG Scenario of Thailands Textile Industry

This study investigated the scenarios of Greenhouse Gas (GHG) emission for Thailands textile industries between 2010 to 2030. GHG emission for Business as usual (BAU) Scenario is increasing from 5.10 to 11.72 Million tons carbon dioxide equivalent (tCO2eq) (approximately 4.3% per year). The IME scenario that new installation of high efficient equipment showed the GHG mitigate as 6.34% in 2030 compared with BAU scenario that including motor, compressor and boiler have contributed as 62.6, 30.6 and 6.8% of the GHG mitigation potential, respectively. On the other hand, the FS scenario which is switching from fuel oil to natural gas mitigates GHG emission as 0.97%.

Low Carbon Scenario for Thailand Power Sector

The objective of this study is to explore the picture of low carbon scenario focusing on Thailand power sector. Impact of related key factors on the emitted greenhouse gases have been evaluated quantitatively, e.g. economic and industrial restructuring, building code upgrading, and fuel switching for power generation. The reference scenario is initially created on the basis of the existing national plan. An alternative scenario of low carbon growth with the additional mitigation options have been comparatively simulated. The results indicate that the existing plan may not lead to the concept of low carbon growth. The proposed mitigation option in the LCS scenario is resulting in the saturated level of greenhouse gases emission in power sector. The emitted GHG can be possibly delinked apart from the growing of economic activities in the emerging country like Thailand.

Potential Study of Electricity Generation 1000 MW with Biogas in Thailand

Thailand, electricity production form biogas has been interested for replacement nuclear and fossil power plants. Current status of electricity production from biogas is 155 MWe, and more potential of current capacity is 380 MWe. Additional, energy crops have a potential for another source of biogas. For this study, electricity production to 1000 MW was determined. Napier grass was considered, high growth rate and high production yield. Napier grass 190,000 acre can produce 1000 MW electricity. And economic analysis of electricity production 1 MW was studied, these results show that biogas for electricity 1MW power plant project is not economic under current condition in Thailand.
