“…Additionally, their syntheses can be performed economically and with no harsh chemicals [16,22,24]. Current research works have focused on developing next generation fuel cells by producing ORR catalysts from naturally abundant materials and waste which are less expensive compared to metal-based catalysts [16,25,26]. This section focuses on the recent use of these materials as carbon sources for highly efficient electrocatalysts.…”

Fuel cells are a promising alternative to non-renewable energy production industries such as petroleum and natural gas. The cathodic oxygen reduction reaction (ORR), which makes fuel cell technology possible, is sluggish under normal conditions. Thus, catalysts must be used to allow fuel cells to operate efficiently. Traditionally, platinum (Pt) catalysts are often utilized as they exhibit a highly efficient ORR with low overpotential values. However, Pt is an expensive and precious metal, posing economic problems for commercialization. Herein, advances in carbon-based catalysts are reviewed for their application in ORRs due to their abundance and low-cost syntheses. Various synthetic methods from different renewable sources are presented, and their catalytic properties are compared. Likewise, the effects of heteroatom and non-precious metal doping, surface area, and porosity on their performance are investigated. Carbon-based support materials are discussed in relation to their physical properties and the subsequent effect on Pt ORR performance. Lastly, advances in fuel cell electrolytes for various fuel cell types are presented. This review aims to provide valuable insight into current challenges in fuel cell performance and how they can be overcome using carbon-based materials and next generation electrolytes.

“…The number of research articles we have on the concept of CE in the context of developing countries, especially that of Bangladesh, is exceptionally limited ( Kirchherr and van Santen, 2019 ). Most of the articles in the context of developing country deals with mostly on waste management ( Abalansa et al., 2021 ; Ali et al., 2021 ; Khan and Ali, 2021 ), and other including in fashion ( Atalay Onur, 2020 ), and renewable energy perspective ( Angulo-Mosquera et al., 2021 ).…”

“…Biofuels are considered alternative or renewable fuels in liquid and gaseous forms obtained from organic feedstocks (Koh & Ghazoul, 2008). Intensive work is being carried out to convert vehicles to biofuels in developed countries, even in countries with oil reserves (Chuvashev & Chuprakov, 2020;Anfilatov & Chuvashev, 2020) due to environmental concerns (Likhanov & Lopatin, 2020), and research is under process in * Corresponding author: cross.j.aa@m.titech.ac.jp developing countries for biofuels production and their usage (Angulo-Mosquera et al, 2021).…”

Many tropical islands, including Aruba, Seychelles, Mauritius, and Pacific Island countries, are entirely dependent on importing fossil fuels to meet their energy demands. Due to global warming, improving energy use efficiency and developing regionally available renewable energy resources are necessary to reduce carbon emissions. This review analyzed and identified biomass feedstocks to produce liquid biofuels targeting tropical islands, particularly focusing on Hawaii as a case study. Transportation and energy generation sectors consume 25.5% and 11.6%, respectively, of Hawaii's imported fossil fuels. Various nonedible feedstocks with information on their availability, production, and average yields of oils, fiber, sugars, and lipid content for liquid biofuels production are identified to add value to the total energy mix. The available biomass conversion technologies and production costs are summarized. In addition, a section on potentially using sewage sludge to produce biodiesel is also included. Based on a comparative analysis of kamani, croton, pongamia, jatropha, energycane, Leucaena hybrid, gliricidia, and eucalyptus feedstock resources, this study proposes that Hawaii and other similar tropical regions can potentially benefit from growing and producing economical liquid biofuels locally, especially for the transportation and electricity generation sectors
