The use of bioenergy feedstocks, agricultural and forest residues constitute a viable decarbonization design with regards to biofuel production. Nevertheless, aspects within agriculture that can be related to this process for instance, include: technology and infrastructure, policies, land use, environmental factors among others. Solving these challenges needs research, technological intervention, supportive policies and acclaimed association among agriculture and energy departments, especially considering that agricultural and forest residues are an abundant source of biomass which can be converted into renewable energy, for example, biogas and hydrogen. This study provides an assessment of the capacity for generating biogas and biohydrogen using the primary biomasses produced in Brazil's agricultural sector, specifically from rice, corn, soybeans, and wheat as alternative bioenergy resources. Data regarding production and waste creation were collected from the Statistical and Geographical Information of Brazilian Agriculture at the Institute of Geography and Statistics of Brazil and the Energy Research Company. Corn and Soybean straw showed the highest potentials for biohydrogen (PH) production, accounting to 6,67 E+09 m3/year and 5,56 E+09 m3/year respectively. The energy production using the generated biogas showed the most satisfactory results compared to biohydrogen, with the highest generation values of 222 TWh of energy for corn straw, 187 TWh for soybean straw. The total accumulated biogas and biohydrogen produced from the residual biomass of Brazil's four main permanent crops was approximately 8.25 E+10 and 1.33 E+10 m3/year, respectively. The generation of biogas and hydrogen holds significant potential for fostering a more sustainable energy future. By utilizing the unique advantages of these two methods—biogas as a waste-to-energy option and hydrogen as a clean and adaptable energy source—we can develop a more robust, varied, and low-carbon energy frame

Low bulk density greatly restricts the large-scale application of electrospun carbon-based fiber membrane as electrode in energy storage devices. To solve the above challenges, herein an orientation-compaction densification strategy is proposed to enhance the bulk density and volumetric capacity of PAN-based carbon nanofiber membranes as self-supporting electrode used in lithium-ion batteries(LIBs). Specifically, highly-oriented fibers are achieved by high-speed roller collecting during electrospinning, and compaction densification is conducted by hot-pressing treatment. The effects of collecting speed and hot-pressing pressure on the morphology, conductivity,bulk density, tensile strength, and flexibility of the obtained carbon nanofiber membrane are *** to conventional fiber membranes, of which fibers are disorderly stacked, the oriented fiber membrane is much easier to achieve dense stacking by compaction. The obtained dense carbon nanofiber membrane demonstrates a bulk density of 0.566 g cm-3, and shows a significantly-enhanced volumetric capacity(318.3 mA h cm-3), high-rate performance(86.6 mA h cm-3at 5 A g-1), and satisfactory cycling stability when used as selfsupporting electrode of LIBs.
