Current Scenario

To cope with the increasing needs of the energy market in current scenario and protect the environment from getting depleted, there is a necessity for a power production technology to be more efficient, cost-effective and eco-friendly. Hybrid systems may provide the solution to these limitations, by maximizing the energy potential of resources, increasing the process efficiency, providing greater security of supply and reducing overall costs. This paper is a proposal to hybridize Concentrated Solar Power (CSP) stirling power plant with biomass.

Thermodynamic Performance

In this paper, a detailed thermodynamic performance analysis of a transcritical condensing (TC) cycle is performed with pure CO2 and a blend of 48.5 % propane with 51.5 % CO2 as working fluids. A realistic thermodynamic model is used incorporating irreversibilities in turbo-machineries and heat exchangers. The Key finding is that the addition of propane elevates the heat rejection temperature, but does not impair any of the performance indicators. Such a fluid may be useful for power generation in concentrated solar power applications by using which a hike of up to 2 % can be realized in the thermal efficiency of a power plant.

This study focuses on two main aspects: developing a novel cost-effective electrode material and power production from domestic wastewater using three different mediators. Methylene blue (MB), neutral red (NR) and 2-hydroxy-1,4-naphthoquinone (HNQ) were selected as electrode mediators with different concentrations. A tin-coated copper mesh electrode was tested as anode electrode. Maximum power density of the microbial fuel cell (MFC) with 300 μM MB was 636 mW/m2. Optimal mediator concentrations with respect to the achieved maximum power output for MB, NR and HNQ were 300 μM, 200 μM and 50 μM, respectively. The results demonstrate that tin-coated copper mesh showed a higher biocompatibility and electrical conductivity.

Technical Operation

The “BIO-Sulfex” biofilter of ATZ-EVUS removes hydrogen sulfide from biogas in a biological way. Hydrogen sulfide causes massive problems during power generation from biogas in a power plant, e.g. corrosion of engines and heat exchangers, and thus causes frequent and therefore expensive engine oil changes. The BIO-Sulfex module is placed between the digester and the power-plant and warrants a cost-effective, reliable and fully biological desulfurization. In the cleaned gas concentrations of less than 100 ppm can be achieved. Power-plant manufacturers usually demand less than 500 or less than 200 ppm. At present, several plants with biogas flow rates between 20 and 350 m3/h are in operation.

E-mail: [email protected]   RESUMO: A utilização de fontes de energias renováveis em sistemas agroindustriais, têm sido uma alternativa no processo de transição energética. No mercado de energia, o principal quesito para a seleção do tipo de geração ainda é o custo. O objetivo deste trabalho, foi demonstrar o desempenho energético de 4 modelos de sistemas heliotérmicos híbridos, acoplados a uma usina sucroalcooleira, atuando no atual mercado de energia por meio do comércio da energia gerada excedente ao consumo. O software System Advisor Model (SAM), foi utilizado nas simulações para a obtenção do desempenho energético e do custo nivelado da energia gerada (LCoE). Os casos foram dimensionados a atender a carga de consumo de uma usina sucroalcooleira, operando em resposta ao recurso solar. A hibridização de sistemas (Concentrated Solar Power) CSP de geração com biomassa disponível durante parte do ano contribui para um bom fator de capacidade. Sistemas de geração, que operam com duas fontes distintas, possibilitam mais segurança de entrega e minimizam riscos, o que contribuiu na formulação do contrato de energia. Os entraves do mercado de energia são possíveis de serem solúveis por meio da aplicação de políticas públicas energéticas, de forma a alavancar a competitividade da tecnologia CSP em relação às demais.   Palavras-chave: energia solar concentrada, geração híbrida, usina sucroalcooleira, mercado de energia, contrato de energia.   LEGAL FRAMEWORK FOR ENERGY TRADE IN HYBRID SOLAR SUGAR ALCOHOL POWER PLANT   ABSTRACT: The use of renewable energy sources in agro-industrial systems has been an alternative in the energy transition process. In the energy market, the main issue for selecting the type of generation still the cost. This paper aimed to demonstrate the energy performance of 4 models of hybrid heliothermic systems, coupled to a sugar and alcohol power plant, operating in the current energy market through the trade of energy generated in excess of consumption. To obtain the energy performance and the leveled cost of energy (LCoE), simulations were carried on the software System Advisor Model (SAM). The cases were sized to meet the consumption load of a power plant, operating in response to the solar resource. The hybridization of CSP (Concentrated Solar Power) systems with biomass available during part of the year can increase the capacity factor. Generation systems, which operate from two sources, provide more secure delivery of energy and minimize risks, which contributed to the formulation of the energy contract. The obstacles in the energy market are possible to be solved through the application of public energy policies, in order to leverage the CSP technologies’ competitiveness regarding other green technologies.   Keywords: concentrated solar power, hybrid generation, sugar/alcohol power plant, energy market, energy contract.

The Waste Power Plant is one of the power plants with a new renewable energy concept that utilizes waste as fuel. The processing of waste into electrical energy is carried out in two ways: the thermal conversion process and the biological conversion process to find the potential for waste that can be used as fuel to generate electricity. The analysis is needed, especially for Pangkalpinang, which currently has a lot of unprocessed waste. This research was conducted through calculations using several formulas that have been used in previous studies. From these results, the potential waste in 2015 is 97.25 tons/day and produces energy of 18548.10 MWh/year, and in 2020, it was about 186.57 tons/day and produced energy of 35547.18 MWh/year. The projection calculations are carried out to determine the potential for 2021 to 2030. Waste as much as 182523 tons/day in2021 can produce energy of as much as 34776.11 MWh/year. And in 2030, the amount of waste as much as 218132 tons/day can generate an energy potential of 41560.69 MWh/year.

Renewable Power Generation

Electricity is a pre-requisite for technological progress and economy growth. Thailand has been facing an electric energy crisis in inadequate electricity generation capacity compared with the demand. It is essential to replace the conventional energy (e.g. fossil fuels) with renewable energy resources, particularly biomass that can play a major role to meet the electricity demand. A modified deming PDCA management has been proposed for power generation. The objective of this study is to evaluate the future electricity consumption as well as to explore the current state of renewable energy potential in Nakhonratchasima Province, Thailand. The results show an electricity energy potential of from agricultural residues, livestock manure and solar energy resources. It is indicated that each these resources can supply the electricity demand excesses. The selection of renewable power generation is mainly driven by the installation cost and the availability of renewable energy resources. The power plant from livestock manures resources is found to be the most promising because its power plant installation requires lower investment in this study.

The Impact

The ground-mounted solar farms are the most common type of Thailand solar power plant. Presently, the area under the solar panels in Thailand had not been utilized. This work was to investigate a suitable configuration for space utilization under the PV panels which could promote power production. The effect of space utilization was investigated for 3 configurations: a water pond, chili cultivation, and a grass plantation. Under the first PV string, the pond sizing 2.4 × 15 meter was created. Under the 2nd PV string, 60 chilies samples were planted. Moreover, the grass was planted under the third string. The intensity of solar radiation (W/m2), temperature, voltage and current of solar panels were also monitoring. The impact of all configurations on the power generation was evaluated and compared with a control.  Results indicated that the space utilization of the first string (the pond) and of the second string (the chili cultivation) generated electricity at 1.6 kW. Both configurations could generate more power than control. The pond and the vegetable plantation were suitable configurations for promoting power production.
