“…Direct carbon solid oxide fuel cell (DC-SOFC) is an allsolid-state device that directly converts chemical energy of carbon fuel into electrical energy. It is feasible to use raw biochar as a fuel in direct carbon fuel cells (DCFC) or hybrid carbon fuel cells (HCFC) (Jafri et al 2018;Kacprzak et al 2016). Biochar as an electrode or catalyst has a promising prospect in microbial fuel cells (Deng et al 2018;Huggins et al 2016).…”

After entering the twenty-first century, biochar has become a focal point of multidisciplinary research because of its special characteristics, broad application, and promising development prospects. Basic and applied research on the application of biochar in the areas of agriculture, environment, and energy have increased dramatically in the face of food security, environmental pollution, and energy shortage. Although there are some disputes about biochar research, many studies have demonstrated the importance of biochar research from the perspective of scientific advancement and practical application. This paper briefly recalls the history of biochar application; introduces research progress on the basic characteristics of biochar and its associated production technologies; summarizes the research status and existing problems of biochar application in the areas of agriculture, environment, and energy; and analyzes the potential problems and development trends of biochar research in the future.

“…The yield of produced biochars was examined under different pyrolysis temperatures. As reported, the pyrolysis process conditions namely temperature, gas pressure, purge gas and heating rate significantly influence the biochar yields [13].…”

“…Based on these results as shown in Table 1, pyrolysis temperature of 550 °C is selected to produce PKS biochar, owing to the highest biochar yield. It has also been reported by researchers that the properties of biochar, such as biochar yield, carbon content, and surface area, are adequately enhanced at around 500 °C when the thermal decomposition of cellulose and hemicellulose is complete [13,17,18]. The physicochemical characteristics of biochar such as elemental composition, fixed carbon, ash, volatile matter, surface area and thermal stabilities are dependent on pyrolysis temperatures [19][20][21].…”

The diminishing fossil fuel reserves and energy shortage are serious challenges that have directed the search for alternative fuel sources for energy generation in the twenty-first century. Biomass-based carbon materials are alternative and renewable fuel sources used for contemporary energy conversion and present a promising solution to the above crisis. This study investigates the possibility of power generation from oil palm kernel shell (PKS) biochar through direct carbon fuel cell (DCFC) technology. The objective of the study is to investigate the potential of PKS biochar as a fuel source and consolidate information on the association between the structure of PKS biochar and its electrochemical performance in a DCFC. The effect of acid pre-treatment on the structure of biochar is also investigated. The samples are characterized on the basis of chemical composition (proximate/ultimate analysis) and DCFC performance in terms of open circuit voltage, power densities and electrochemical impedance spectroscopy. The results indicated that carbon, ash and oxygen functional groups on the carbon surface have a major impact on the fuel performance in the DCFC. At DCFC operating temperature of 850 °C, the pre-treated PKS biochar exhibits a maximum power density of 3.3 mW cm −2 which exceeds that of untreated PKS biochar and activated carbon. Besides high carbon and reduced ash in the biochar, the results suggest that the existence of oxygen functional groups in the pre-treated PKS biochar also plays a crucial role in cell performance by providing additional active sites for electrochemical reaction.

“…Significant effects were found. Because of this treatment, the elements obtained from the application of biochar were very influential and durable in the soil (slow release), so that in subsequent cropping systems the availability of nutrients could be used and crop yields did not experience a significant decrease [10] [11].…”

Degraded land occurs due to the decrease in soil quality, which is often resulted from continuous planting without considering the quality of the soil. This study aims to reduce damage to soil fertility, control soil degradation, and increase the production of cassava and maize crops. The research was conducted in Junrejo village, Batu. Two types of biochar (chicken manure biochar and corn cob biochar) were used on cassava and maize intercropping. This study used three treatments: control, biochar chicken manure, and corn cob biochar. The study used a randomized block design with two factorials with a 5% analysis of variance and the smallest significant difference (LSD). The results showed that the application of biochar chicken manure and corn cob biochar significantly improved soil quality and increased the production of maize and cassava crops. Also, it proved effective for land use, thus controlling and reducing soil degradation. The soil quality was improving, and so was the cassava and maize yield. The highest yield was from cassava and maize intercropping with the application of chicken manure biochar (cassava 18.33 Mg ha-1, maize 3.89 Mg ha-1), while monoculture cropping system with the application of corn cob biochar production was 4.07 Mg ha-1 for maize, and 32.81 Mg ha-1 for casava. The highest land use efficiency of cropping system intercropping cassava and maize after application of corn cob biochar was 1.03 and 0.72. It shows that the improvement of soil quality in intercropping of cassava and maize system after the application of corn cobs biochar was very effective so that land degradation could be avoided.
