Message from Director

Dr. Sukruedee Sukchai

In 2011, the School of Renewable Energy Technology (SERT), Naresuan University used new strategy in managementto increase research productivity, reduce academic services which was too many. We tried to select and work for theacademic services that can be integrated into learning, teaching, and academic services that the staff can createresearch problem.

So the several changes occurred in the organization. With the collaborative efforts of both staff and students withinSERT, This helps to reach the target very soon. The School prepared this Annual Report to publicize the activities of theschool. We hope this might be benefit for those who are interested.

The School commits to the development of academic activities in the next year even better. The School would like tothank all of you who kindly supported the School.

Research Activities

Research: Tar Reduction in Producer Gas by a Thermosyphon Heat Pipe Heat ExchangerSahataya Thongsan, Sukruedee Sukchai, Somchai Jiajitsawat, Bongkot Prasit and Sasithorn Lertmaneepong

This research presents the simulation of a thermosyphon heat exchanger for producer gas cleaning of a gasificationpower generation system by decreasing temperature of the gas to tar dew point. In this project, Eucalyptus residuals areused as fuel for gas production in a fixed bed down draft gasifier. The temperature and flow rate of the gas at the gasifieroutlet experimentally measured were 250�C and 135 m3/h, respectively. A proposed heat exchanger is employed todissipate the heat out of the hot gas till the tar dew point is reached and then condensed. This heat exchanger consistsof copper-tube heat pipes filled with water at 50 % of heat pipes’ evaporator. Each heat pipe has 100 cm in length, 2.23cm in diameter, and 1.994 cm in internal diameter. The heat exchanger performance was simulated and optimized byvarying the number of heat pipes.

The result from the simulation was shown that 205 heatpipes calculated can reduce the temperature of producergas to the tar dew point. An experimental validation of thesystem performance is in progress.

Research: Technology Transfer of A Jar-Biogas Digester to Community: KlongKoo Village, Tha-pho District,PhitsanulokPisit Maneechot, Prapita Thanarak and Wikarn Wansungnern

The Energy for Community research unit, School of RenewableEnergy Technology, Naresuan University, developed a jar-typedbiogas digester for cooking gas production to substitute theLPG in order to help people independent from its increasingprices. The developed digester was successful in operation,practical, and worth in investment. This concept of technologytransfer to the community is consistent with one of the schoolmissions.

The objectives of this project are: 1) to transfer knowledge of ajar-typed biogas digester technology to the community forapplying in their daily life and to correctly and effectively transferto other communities and 2) to be used as an approach indevelopment and promotion of technology usage widely andcontinuously.

A family of Mr. Boomee Comemon, 41 year-old with 4 members,inhabiting at 8/1 Moo 4 Tamboo Tapho, Amphoe-Muang,Phitsanulok, 65000, was chosen as a representative family forthe experimental testing of the developed biogas digester.

The result of this study presents that LPG consumption of thehousehold is about 315 Baht per month. The average biogasquantity is 0.152 m3 per day while adding animal waste 1-2 kgper day. This amount is appropriate to household of 3-4members and total expense saving is 3,780 Baht per year.If the investment cost is 6,611 Baht (exclude labor cost), thesimple payback period calculated is 1 year and 9 months.Increasing LPG market price will cause payback period shorter.

Biogas production from 1,900 liters of animal and householdwaste with 120 liters storage tank is suitable for 3-4 members.This household should have 3-4 pigs and have medium-understanding on biogas production. The biogas technologytransfer should be simple and effective to promote to thecommunity. There are community energy volunteers that mayhelp to distribute their skill and knowledge to the villagemembers. Hence, all these factors will make the technologytransfer successful and sustainable.

This research presents the study on carbon dioxide emission reduction from large scalephotovoltaic (PV) power plant in Thailand using a method based on Annex 14 MethodologicalTool (Version 02) “Tool to calculate the emission factor for an electricity system”. The calculationresult is coefficient of green house gas emission factor (Combined Margin Emission Factor) forsolar electricity generation is 0.5980 tCO2/MWh. Besides that the study on economic analysisof large scale PV power plant in Thailand, with interest rate at 6.75%, benefit from selling CO2in 7 years shows that net present value (NPV) is 2,472,187,645 Baht, benefit cost ratio (BCR)at 12.52, economic internal rate of return (EIRR) is 20.01%, cost of energy (COE) is 7.96 Baht/kWh and payback period less than 5 years. The sensitivity analysis also presented in thisresearch. Considering the degradable PV efficiency and initial cost have positive economicindicator results. However, adder cost at 6.5 Baht/kWh and interest rate at 10% and 15% makenegative economic indicator results. Also considering the different of energy yield at 1,400kWh/kWp found that internal rate of return is 6.66% which is less than interest rate at 6.75. Thus, allPV entrepreneurs are agreeing for bright and growing future of PV industrial business in Thailand.

Thailand Government has a policy to promote the production of renewable energy and it imposesthe way for supporting another production of renewable energy by Ministry of Energy. It imposesthe goal of using a renewable energy for producing electricity in 2022 is 3,700 MW. However,the supporting of using biomass in industrials still have problems in management of using fuel,which spread in the area efficiently, it affects in situation of fuel purchase, high transportation,and the cost of electricity from biomass. So it has to consider the benefit of environment inproducing of electricity from biomass. The way of reducing Carbon dioxide emission is a processof Clean Development Mechanism (CDM). It is a choice to do in this project. In Thailand, thereis project CDM about 18.95 % and ,it has a certification of Letter of Approval (LoA) about 160projects.The research aims to study of reducing of Carbon dioxide from production of electricity energyfrom biomass for a small community power plants by using the information of agricultural productsin 2003-2008 from survey in 9 the Lower Northern region of Thailand such as KamphaengPhet, Tak, Nakhon Sawan, Sukhothai, Phichit, Phitsanulok, Phetchabun, Uttaradit, and UthaiThani that have agricultural waste such as rice husk, corncob, bagasse, and Cassava rhizome.There are 7,608,080 tons per year which calculate the potential to establish a small communitypower plant is 250-500 MW. According to the amount of leaving Carbon dioxide of Annex 12Methodological tool (Version 01.1) “Tool to calculate the emission factor for an electricity system”found that the potential was reduced Carbon dioxide about 1,000,269-2,000,592 corbon dioxidetons per year. The amount of each type of agricultural waste; rice husk, corn cob, bagasse andcassava rhizome, from survey and interview, are no correlation with the planting area or provincesor planting year. From economic analysis in rate of the project size is 1.2 MW, it reduces about7 %, Net Present Value is 161,539,087 Baht, Benefit-Cost Ratio (BCR) is 1.85, and InternalRate of Return (IRR) is 21%. Payback period is 8.86 years, besides that, Cost of Energy (COE)is 5.73 Baht. It indicates that the project will have a profit for be worth to invest which is a profitfor investment, and it can be manage. For the sensitivity analysis for evaluating of compensationafter changing the factor which effect to produce electricity such as amount of fuel and cost offuel which change to 10 P.C. and analyze a sensitive of the project causes technician problemsin power plants. So it was stopped to run a machine. From the study of all cases show that theproject has IRR more that rate of reducing and NPV increase. According to Net Present Value,the cash inflow more than cash outflow, moreover, the ratio between the interest of project andthe total of investment calculate from Net Present Value or Benefit-Cost Ratio more than 1.Therefore, this study show that although the project will effect from changing in capital investmentand beneficial, the project of community of power plants from biomass size is 1.2 MW have aprofit for investment and compensation for investment which can be run to continue the project.
