Rich in renewable resources, extensive acreage, and bioenergy expertise, Brazil, however, has no established strategies for sustainable aviation fuels, particularly e-kerosene. We extend the lens from the often-studied economic feasibility of individual e-kerosene supply chains to a system-wide perspective. Employing energy system analyses, we examine the integration of e-kerosene production into Brazil’s national energy supplies. We introduce PyPSA-Brazil, an open-source energy system optimisation model grounded in public data. This model integrates e-kerosene production and offers granular spatial resolution, enabling federal-level informed decisions on infrastructure locations and enhancing transparency in Brazilian energy supply scenarios. Our findings indicate that incorporating e-kerosene production can bolster system efficiency as Brazil targets a carbon-neutral electricity supply by 2050. The share of e-kerosene in meeting kerosene demand fluctuates between 2.7 and 51.1%, with production costs varying from 113.3 to 227.3 €/MWh. These costs are influenced by factors such as biokerosene costs, carbon pricing, and export aspirations. Our findings are relevant for Brazilian policymakers championing aviation sustainability and offer a framework for other countries envisioning carbon-neutral e-kerosene production and export.

“…(1) The collection or centralized management of gases that are harmful to the environment; and (2) the resource utilization of the exhaust gas. For example, the biochar production process produces a large amount of methane, which can be recycled and processed for combustion to generate electricity . Therefore, the recycling and reuse of methane reduces not only the impact of electrical energy consumption but also the negative impact on ecosystem quality.…”

Value-added biochar or hydrochar converted from agricultural waste has the potential to improve soil performance. However, how biochar and hydrochar addition affect ecological responses is not clear. Here, we examined the physicochemical property of biochar and hydrochar from straw (RS) and manure (SM), identified relevant eco-friendly pretreatment methods through life cycle assessment (LCA) methodology, and investigated their influences on soil properties and C and N cycles. The results showed that biochar prepared at 500 and 700 °C and hydrochar prepared at 250 °C for 4, 6, and 8 h had better physicochemical properties. The LCA results revealed that RBC500, RS250-4, and SM250-4 had lower environmental burdens in the preparation process. Moreover, biochar and hydrochar addition could promote the soil C and N cycles to varying degrees, especially in the case of SM250-4, which could simultaneously promote the degradation of cellulose, lignin, and chitin and reduce the emission of CO2 and N2O. Overall, SM250-4 application had a beneficial effect on carbon neutralization. These novel results compensate for the deficiency of research on the phaeozem improvement effects of biochar and hydrochar.
