“…The experiment was carried out using direct co-firing method without any modifications at the circulating fluidized bed boiler Unit 2, with a capacity of 100 MWe, located in Balikpapan, Kalimantan, Indonesia, as shown in Figure 4. This test method was conducted in previous studies using another biomass (Cahyo, Alif, Hapsari, et al, 2021;Cahyo, Hariyostanto, et al, 2022). For the 3% ratio of co-firing test, with a duration of 4 hours, 8.4 tons.…”

“…Experiments have also been conducted using sawdust in an approximately 5% blend-in boiler with a 330 MWe capacity (Tanbar et al, 2023). In Circulating Fluidized Bed Boiler, trials including palm kernel shell co-firing in proportions ranging from 5% to 10% were conducted to assess operational performance, fuel cost-effectiveness, and emission characteristics (Cahyo, Alif, Hapsari et al, 2021;Cahyo, Hariyostanto, et al, 2022). Additionally, Pulverized Coal Boiler with tangential firing systems and a 315 MWe capacity were tested for co-firing with wood pellets to observe the impact on boiler efficiency, emission, and operational parameters.…”

“…Co-firing with palm kernel shells has shown the potential to reduce furnace exit gas temperature (FEGT), bed temperature, SO2, and NOx emission and increase fuel consumption (Cahyo, Alif, Hapsari, et al, 2021). Furthermore, it saves fuel cost by ranging from 0.23 cents/kWh to 0.31 cents/kWh compared to coal firing condition, assuming 1 USD = 16,250 IDR).…”

The study aimed to explore the effects of biomass co-firing of coal using acacia wood bark at circulating fluidized bed (CFB) boiler coal-fired power plant with 110 MWe capacity. The analysis focused on main equipment parameters, including the potential for slagging, fouling, corrosion, agglomeration, fuel cost, and specific environmental factors. Initially, coal and acacia wood bark fuel were blended at a 3% mass ratio, with calorific values of 8.59 MJ/kg and 16.59 MJ/kg, respectively. The corrosion due to chlorine and slagging potential when using wood bark was grouped into the minor and medium categories. The results showed that co-firing at approximately 3% mass ratio contributed to changes in the upper furnace temperature due to the variation in heating value, high total humidity, and a less homogeneous particle size distribution. Significant differences were also observed in the temperature of the lower furnace area, showing the presence of a foreign object covering the nozzle, which disturbed the ignition process. A comparison of the seal pot temperature showed imbalances as observed from the temperature indicators installed on both sides of boiler, with specific fuel consumption (SFC) increasing by approximately 0.17%. During the performance test, the price of acacia wood bark was 0.034 USD/kg, resulting in fuel cost of 0.023355 USD/kWh, adding 0.061 cent/kWh to coal firing cost. Despite co-firing, the byproducts of the combustion process, such as SO2 and NOx, still met environmental quality standards in accordance with government regulations. However, a comprehensive medium- and long-term impact evaluation study should be carried out to implement co-firing operations using acacia wood bark at coal-fired power plant. Based on the characteristics, such as low calorific value, with high ash, total moisture, and alkali, acacia wood bark showed an increased potential to cause slagging and fouling.

“…Therefore, the world is transforming toward renewable energy to fulfill the global need for power. Moreover, worldwide electricity demand is expected to increase by 2.1% annually until 2040, so the energy sector's sustainability is urgent [1]. Renewable energy emanates from natural sources that are replenished at a higher rate than consumed.…”

The growth in global electricity demand, price volatility, and global warming is diverting the attention of power producers to look for alternative green energy sources, more specifically, solar photovoltaic (SPV). Rooftop solar PV (RSPV) is a significant contributor to the successful development and deployment of SPV in any country. Therefore, developing countries such as the Kingdom of Saudi Arabia (KSA) are seeking alternative energy sources. According to climatological studies, Saudi Arabia has an average of 3230 sun hours annually, indicating significant potential for producing solar energy. The article investigated the characteristics of policies of countries that have had massive success in developing RSPV systems like China, the US, Germany, Italy, Spain, Japan, and India). Each country has its unique policies that result in many policy structures. Therefore, it is beyond the content of this report to provide a complete overview of all policies for the selected countries. Instead, information will focus on specific aspects of solar policy in each of the seven countries. As part of the RSPV policy assessment in Saudi Arabia, this study shows the key vectors of the selected countries’ success in their rooftop policies’ examination, and eventually, it presents a clear policy assessment of KSA’s rooftop solar PV policy.
