Biomass Energy: A Crucial Component in the Renewable Energy Mix

Prediction of Performance and Emissions Diesel Engines Fueled-Biodiesel Using Artificial Neural Network (ANN) Resilient Backpropagation Algorithm (Rprop)

In order to increase energy security and improve environmental quality, the Indonesian Goverment set a target of 23% renewable energy mix in 2025, one of which is the Mandatory Bioediesel Program. A higher biodiesel blending ratio will affect the performance and emissions of diesel engines because biodiesel is chemically different from diesel oil. Research related to the prediction of diesel engine performance and emissions using Artificial Neural Network (ANN) has been conducted, but the author sees a research opportunity for the implementation of the ANN Resilient Backpropagation (Rprop) algorithm. The data used to create the ANN model prediction was secondary data from previous research. The model designed multi input and multi output (MIMO) with 4 input variables and 7 output variables. Model building done by varying the number of neurons and hidden layers. Model evaluation selected based on the largest coefficient of determination parameter R2 and the smallest RMSE or MAPE. The results showed that the ANN single layer 4-20-7 network architecture is the best model for predicting diesel engine performance and emissions with test data R2 , RMSE and MAPE of 0.962532, 6.699428 and 6.0% respectively, while for overall data testing has a performance of 0.982869, 3.908542 and 4.3%. The results also show that based on the ANN prediction results, the increasing biodiesel ratio can increase NOx emissions and decrease HC, CO and CO emissions2 . In terms of performance, the addition of biodiesel can increase BSFC and BP and decrease BTE. The results also show that the addition of ZnO concentration can reduce emissions while in terms of performance it will increase BTE and reduce BSFC and BP.

Breakthrough on Indonesia’s Energy Policy: Adaptive Governance Perspective for Just Energy Transition Partnership (JETP)

Abstract The Just Energy Transition Partnership (JETP) agreement strives to attain a peak emissions level of 290 Mt CO2eq by 2030 in the power sector while targeting a 34% renewable energy mix. To support these goals, a minimum of 20 billion USD from public sector pledges and private financial institutions is allocated for expedited decarbonisation. This entails retiring coal-fired power plants and concurrently developing renewable energy-based generation. However, implementing the JETP initiative encounters regulatory and technical challenges in Indonesia, arising from conflicting stakeholder interests, inconsistent regulatory frameworks, opposition from established incumbents of fossil fuels industries, and limited implementation capabilities. These barriers pose a significant threat to the efficacy and efficiency of the JETP program. Consequently, enhancing adaptive governance, namely, polycentricity, learning, diversity, deliberation, participation, flexibility, responsiveness, political support, and collaboration, is crucial to mitigate potential obstacles, bolstering the probability of success for the JETP program.

Analysis of Biomass Co-firing Combustion Test using Corn Cobs at Punagaya CFPP as A Green Energy Alternative

Abstract Indonesia is determined to reduce fossil fuels by 2060 set a national renewable energy mix target of 23% by 2025 and be free of fossil fuels by 2060. One of the PLN’s (a national electrical company in Indonesia) efforts to increase carbon emissions reduction and strengthen local new renewable energy is co-firing biomass on CFPP. Indonesia, which is located in a tropical area, has a large potential for biomass resources. Corn cob, one of the biomass types, has a big potential to replace coal as fuel in CFPP especially in Jeneponto Region, South Sulawesi. By utilizing corn cobs as a fuel with a co-firing mechanism, it can generate green energy. The methodology for assessing the corn cob co-firing combustion test’s performance at Punagaya CFPP is presented in this paper. It is based on a multi-criteria assessment designed to examine the technical, financial, and environmental effects of operating parameters with a mixture composition of 95% coal and 5% corn cobs at 70 MW load for 10 hours. From the test results in terms of operational aspects, the parameters have changed but it still in the normal operating range; FEGT increased by 5.3°C, bed temperature increased by 8.9°C, air chamber pressure decreased by 0.05 kPa, and total airflow decreased by 4.5 T/h. From the financial aspect, it has benefited from a decrease in the value of Specific Fuel Consumption (SFC), which is 0.014 kg/kWh compared to 100% coal. From the environmental aspect, the overall results of emission parameters are still by environmental quality standards and have decreased for NOx and SO2 parameters.

Determinants of carbon emissions in Kenya and policy implications

Carbon dioxide emissions are the primary greenhouse gasses behind global climate change and its associated effects. Climate change adversely impacts the environment, biodiversity, and human health. The ability to tame carbon dioxide emissions will help in the fight against climate change. However, the recent pace of rising carbon dioxide emissions raises concerns about winning the war against climate change. World leaders are determined to take actions that will lower emissions. Thus, there is a worldwide effort to achieve net-zero emissions. Consequently, it is crucial to comprehend the specific factors that contribute to carbon emissions of specific economies so that countries can develop and enforce effective strategies for reducing carbon output, mitigating the effects of climate change, and improving recovery programs. Despite many empirical studies conducted in Africa on the determinants of carbon emissions, the results remain inconclusive and inadequate, leaving a void for further research. This study seeks to fill this knowledge gap by modeling the relationship between Kenya's carbon emissions (which have been increasing since the early 2000s), and mobile technology adoption, renewable energy mix, tourism development, development assistance, income, and global financial crises, utilizing the most current data from 1995 to 2021 from the World Bank's database. The ARDL, FMOLS, CCR, and DOLS analysis results reveal that mobile technology, tourism, development aid, and global financial crises increase Kenya's carbon emissions in the long run. At the same time, income and renewable energy reduce short- and long-term impacts. The significant insight from these results is that enhancing renewable energy development, mobile technology, and development assistance can promote a sustainable environment. From these findings, the study proposes many policy recommendations to help decision-makers, communities, companies, and the government in Kenya allocate resources and implement resilience and mitigation policies and programs in the areas most susceptible to the effects of climate change.

Strategic integration of residential electricity: An optimisation model for solar energy utilisation and carbon reduction

The Solar Combined Cooling, Heating, and Power (S-CCHP) system, distinct from traditional centralised generation, provides clean energy solutions by installing user-side renewable energy capture facilities like solar panels to address the energy crisis and mitigate global warming. Previous research on the design of S-CCHP for buildings has often emphasised self-sufficiency, with less focus on the role of these systems as energy suppliers on the market. However, it is feasible to install scaled-up solar facilities that generate enough power to export to the grid, reducing grid pressure and enhancing the renewable energy mix. This study analyses the optimal design deployment for electricity within the S-CCHP system, based on the Renewable Energy System for Residential Building Heating and Electricity Production (RESHeat) system installed in Limanowa. It aims to optimise owner energy deployment by strategically integrating electricity generation, hybrid storage, and the electricity market to maximise owner benefits. A Life Cycle Assessment is also conducted to explore greenhouse gas emissions across scenarios with different storage facilities and reuse rates. Results show that the optimal deployment of 264 PV panels, each with a rated power of 440 W, generates 105 MWh annually, resulting in the surplus of 90.18 MWh with a selling price of 115 EUR/MWh. Vanadium redox flow batteries offer the highest revenue (4922.01 EUR) with the lowest storage costs, while lithium-ion batteries have the lowest carbon emissions (1.22 t CO2 eq/y). Sensitivity analysis and revenue break-even analysis are further conducted to assess the robustness and financial viability.

Characterization of Wood, Leaves, Barks, and pod wastes from Prosopis africana biomass for biofuel production

One of the approaches for increasing the contribution of biomass to the renewable energy mix is the valorization of biomass to bioenergy. Evaluating the potential of unconventional biomass sources could significantly accelerate the assessment for suitability as feedstock for bioenergy production as a sustainable solution. The study aimed to characterize the Prosopis africana biomass of wood, barks, leaves, and pods towards providing valuable data for scaling up and incorporating these materials into the bioenergy crop database. Characterizations of wood, leaves, barks, and pod wastes from Prosopis africana biomass were investigated based on the proximate, ultimate, and compositional analysis of pulverized samples of the PA biomass to determine their physical, thermal, and chemical properties towards assessing their potential for valorization to bioenergy. The lignocellulosic materials were characterized by scanning electron microscopy, energy dispersive X-ray, Fourier transform infrared spectroscopy, thermogravimetric analysis, and X-ray diffraction. The results show that the pulverized sample wastes have porous structures with varying degrees of crystallinity (wood: 89.20 %, bark: 23.90 %, leaves: 32.48 %, pods: 23.08 %), suggesting different susceptibilities to conversion processes. Notably, the wood sample had the lowest moisture content (3.13 %), and the pod sample had the highest volatile matter content (75.83 %), indicating a high potential for biofuel production. The higher heating values (HHV) and lower heating values (LHV) of the samples ranged from 15.23 to 20.49 MJ/kg and 13.83 to 18.79 MJ/kg, respectively. These calorific values are competitive with established lignocellulosic bioenergy feedstocks, positioning PA biomass as promising candidates for solid biofuel applications.

Future-proofing for green hydrogen in the Global South: a procedural justice perspective

Green hydrogen provides one solution for a just transition to a low-carbon economy in the Global South. Absorption of green hydrogen into the energy mix will assist in decarbonising the hard-to-abate sectors, and it may even contribute to the economies of these countries when they transport to the Global North which has excess demand for it. However, this new pivot may also introduce new energy injustices, and this is what this paper focuses on. Through a comparative law analysis of three countries each from the Asia-Pacific (China, Vietnam and Thailand), South America (Brazil, Chile and Colombia) and Africa (South Africa, Kenya and Namibia), and by looking through the lens of procedural justice, this paper marks the first comprehensive examination of this concept for green hydrogen. It analyses the trajectory of these countries in terms of their introduction of green hydrogen into their renewable energy mix. Then there is an assessment of their successes and failures, the identification of gaps in policy, and the role of procedural justice in moving the green hydrogen legal frameworks forward is also examined. Finally, policy solutions to future-proof green hydrogen legal frameworks for the attention of policymakers are advanced.

Energy, exergy, environmental and economy (4E) analysis of the existing of biomass-ORC plant with capacity 150 kWe: A case study

Biomass makes a substantial contribution to Italy’s renewable energy mix. In 2018, 19,235 GWh of energy were created, continuing a trend that began three years earlier. Italy’s demand for biofuel is expected to reach 2.8 million tonnes of oil equivalent by 2025 and remain constant until 2040. Biomass combustion frequently generates high temperatures (900–1000 °C), which justifies the construction of high-temperature heat recovery units such as steam Rankine or supercritical carbondioxide (SCO2) cycles. However, these methods are only economically practical on a medium to large scale. Small-scale units have high component costs because of the high specific volume of steam, while high turbomachinery costs mostly hamper small sCO2 systems. So, another alternative way is to use an organic Rankine cycle (ORC). This study uses thermodynamic analysis to determine how much power can be achieved in terms of energy, exergy, economy and what impact on sustainability is achieved at the Bologna ORC plant. From the study results, it was found that the Bologna unit has a capacity of 150 kWe. When data was collected, the maximum power obtained was 85 kW at a temperature and pressure of 153 °C and 1.84 MPa, respectively. Biomass-ORC investment is economically competitive, with NPV and LCOE values of 238 kE and 0.93 E/kWh, respectively, and a simple payback period of 24 years for residents with yearly energy needs of 2000 h.

Power Sector Under Climate Scenario: A Study of Climate Policy Impact on Indonesia Electricity System

In the sixth assessment report, the IPCC indicates that global temperature increased by 1.11 (±0.13) degrees Celsius in 2019 due to 6.5 gigatons of CO2eq of greenhouse gas emissions into the atmosphere. The power sector is a major global greenhouse gas emitter, particularly in Indonesia. Indonesia’s electricity sector emitted 149.90 million tons of CO2eq greenhouse gas in 2020, which is expected to increase to 158.30 million tons of CO2eq in 2021. Indonesia has committed to reducing greenhouse gas emissions according to the Paris Agreement. The Paris Agreement has been ratified into national law, accommodating Indonesia’s roadmap to net zero by 2060. The emissions reduction target was published in 2022 through the enhanced Nationally Determined Contribution (NDC). This study aims to analyze the impact of climate policy in Indonesia’s electricity sector to meet the net zero emissions target by 2060. Projection and calculation in this study were conducted using the Low Emissions Analysis Platform (LEAP). Data from 2020, including electricity demand, existing capacity, energy production, energy intensity, lifetime, and capacity factor, were used to support LEAP analysis. The data were obtained from the PLN statistical book, PLN sustainability report, Indonesia’s statistical book, and climate change mitigation and adaptation reports in Indonesia. This study developed three climate scenarios, including business as usual (BAU), sustainable development (SD), and low-carbon development (LCD). These scenarios draw upon current climate policies that have various impacts on electricity generation in Indonesia. Based on LEAP analysis, by 2060, energy demand is expected to increase to 300.36 MTOE (BAU), 200.93 MTOE (SD), and 76.97 MTOE (LCD). Consequently, each climate scenario requires an increase in installed capacity to 821.82 GW (BAU), 727.06 GW (SD), and 334.58 GW (LCD). The renewable energy mix is projected to be 21% (BAU), 69% (SD), and 100% (LCD). Each scenario requires investment to develop capacity to meet energy demand. The investment cost is estimated to be 1,671.58 million USD (BAU), 1,537.64 million USD (SD), and 816.51 million USD (LCD). GHG emissions are projected to rise to 1,746.31 million tons of CO2eq (BAU) and 264.39 million tons of CO2eq (SD). However, the LCD scenario expects to achieve net zero emissions by 2060.

Smart energy planning for the decarbonization of Latin America and the Caribbean in 2050

Latin America and the Caribbean is a region that has grown enormously in public policies and especially in the implementation of renewable energy generation plants, which is why it deserves to study its growth to provide long-term deep decarbonization routes. It has approximately 634 million inhabitants, and it is expected that by 2050 it will reach 784 million inhabitants, which worries researchers to establish a new model of energy supply in accordance with future demand. The concern does not end here, the new energy supply must be friendly to the environment and renewable energies are the appropriate option to avoid the increase in global temperature. The challenge of this research is to provide an adequate option for the decarbonization of Latin America and the Caribbean to achieve 100 % renewable energy by 2050. For this purpose, the energyPLAN tool is used, a flexible tool, very useful to transform large energy systems based on fossil fuels and achieve comprehensive 100 % renewable markets. Power systems are considered a challenging task and are widely studied around the world to avoid the great negative effects of altering the climate. Modeling the zero carbon energy system was implemented using the concept of smart energy. The combination shows that it is necessary to use a wide variety of energy sources and that no energy source more than 35 % stake, to increase energy security. The historic hydroelectric technology will continue to be an essential part of the Latin American energy mix. However, in 2050, the technologies that are destined to have the greatest participation will be wind turbines and solar photovoltaic with 32.7 % and 31 % respectively. Technologies with less participation such as renewable thermal and geothermal are also identified. Achieving a 100 % renewable energy mix by 2050 will prove to be economically beneficial. Based on the results obtained, it will be effective to achieve a 100 % renewable scenario when Latin America and the Caribbean form a solid regional alliance exclusive to fight for the environment and legislate favorably so that its member countries contemplate important budgets in a conscious, responsible and supportive way.

Urban Waste Management Solution through SRF Cofiring in Coal-Fired Power Plants

Abstract Solid Recovery Fuel (SRF) is a highly effective waste product processed through sorting and separation from non-combustible materials in Indonesia. The SRF is then dried to increase its calorific value and ensure homogeneity. Most Indonesian SRF is derived from urban waste, which is predominantly organic material, making it comparable to biomass and having a calorific value akin to lignite coal. The state-owned electricity company, PLN, collaborates with local governments responsible for waste management to utilize SRF as a fuel source in coal-fired power plants through cofiring. This renewable energy mix is an optimal solution, eliminating the need to construct new power plants and optimize waste management programs and local government budgets without burdening PLN’s operational costs when managed through an appropriate collaborative scheme. PT PLN Indonesia Power has successfully conducted research and development efforts to transform urban waste into SRF through the Waste Treatment Facility program. They have also utilized SRF cofiring in coal-fired power plants up to the heat rate testing stage. This alternative solution benefits all stakeholders in addressing the waste management challenge. This program presents an opportunity to optimize waste management costs implemented by local governments, ultimately saving electricity generation costs. Moreover, it may help reduce the financial burden of constructing and operating conventional solar power plants. SRF cofiring in coal-fired power plants is a reliable and cost-effective renewable energy solution. The successful pilot project showcased the positive outcomes achievable through a collaborative management scheme that utilizes SRF products and environmentally friendly electricity generation for sustainable waste management. This approach effectively reduces greenhouse gas emissions and enhances renewable energy generation capacity, highlighting the significant impact possible through this method.
