“…storage and transportation (Mafakheri & Nasiri 2014). Nonetheless, substituting a fossil fuel with a biomass may result in highly variable GHG mitigation depending upon how the biomass is generated (Serra et al 2019). Because of this, a thorough study on the impact of utilizing biomass is required to confirm its environmental advantages over fossil fuels.…”

Depleting stockpile of fossil fuels and rising global temperature due to the greenhouse effect are probably the two most threatening factors to civilization sustainability. Converting biomass into a readily available energy source will help reduce dependency on fossil fuels, whilst at the same time moderating greenhouse gas emmissions due to its carbon neutrality. Palm oil industry is the largest source of biomass in Indonesia and the available quantity to be utilized is growing inline with the steady growth of the generating industry. Among various wastes from palm oil processing, palm kernel shell is an oil palm biomass with high potential to be applied as a source of energy, given its high caloric value and distinctive physical properties. This source of renewable energy can be utilized by industries with thermal conversion processes. As a prerequisite, a feasibility study on technical, environmental, and economic aspects needs to be carried out. From long term perspective, supply, demand, and regulatory situational analysis will also be required. Lastly, a review on the existing palm kernel shell supply chain will help to understand its current situation. Based on literature studies and field observations, we have identified supply and demand characteristics that will be valuable in constructing an effective, efficient, and sustainable supply chain model of palm kernel shell. Understanding these characteristics is a precursor in realizing this massive potential of renewable energy source in the industrial context.

“…With the increasing scarcity of nonrenewable resources and the exacerbation of global climate change, renewable energy has become a viable and critical energy source for reducing greenhouse gas emissions and meeting global energy demands. , Due to the influence of the surrounding geographical environment, most renewable energy sources are intermittent and volatile. The effective integration of renewable energy into the existing grid will face challenges of efficiency, stability and reliability.…”

Lead−carbon batteries (LCBs) and conventional lead−acid batteries (LABs) exhibit similar advantages in terms of safety, cost, and stability. The addition of carbon material to the negative plate can considerably alleviate the irreversible sulfation of the negative plate of the battery and significantly extend its cycle life. However, due to the low hydrogen evolution potential of carbon materials, when added to the negative plate, it will cause serious hydrogen evolution. In this paper, porous corn cob biochar (CCB) composites (Bi 2 O 3 @C-4) with high hydrogen evolution potential were prepared by in situ thermal synthesis method on CCB substrate. A large amount of Bi and Bi 2 O 3 adhere to the surface of Bi 2 O 3 @C-4 and occupy the adsorption site of H + , which slows down the hydrogen evolution rate and increases the hydrogen evolution potential. Furthermore, Bi 2 O 3 @C-4 has mesoporous and macroporous structures, which not only enable the storage of electrolytes but also provide channels for ion transport to accelerate the conversion of Pb/PbSO 4 , effectively inhibiting the formation of large PbSO 4 crystals. In addition, the interior of the macropores also offers nucleation sites for the deposition of Pb 2+ . Finally, the effect of Bi 2 O 3 @C-4 as an additive on the performance of LCBs was elaborated. At a discharge rate of 0.1 C, the initial discharge-specific capacity of LCBs with added Bi 2 O 3 @C-4 (167.7 mAh g −1 ) was 47% higher than that of the blank batteries (114.1 mAh g −1 ). The high-rate partial state of charge (HRPSoC) cycle life test with a discharge rate of 1 C results in a cycle life of Bi 2 O 3 @C-4 (36,524 cycles) that is 5.1 times longer than that of a blank battery (7,169 cycles). In conclusion, Bi 2 O 3 @C-4 exhibits a dual synergistic effect of high hydrogen evolution potential and porous structure, which not only reduces the hydrogen evolution rate of the negative plate, but also inhibits the irreversible sulfation of the negative plate, providing valuable insights for enhancing the performance of LCBs.

Feedstock resources for renewable natural gas (RNG) production by biological (e.g., anaerobic digestion) and thermochemical (e.g., gasification) conversion methods in Hawaii have been reviewed. Statewide estimates of RNG production potential from urban resources (wastewater, existing landfills, foodwaste, construction and demolition waste (CDW), and municipal solid waste) total 8860 TJ year À1 . Honolulu has the largest resource base for these urban waste streams. Underutilized agricultural land resources in the state could support substantial RNG production from dedicated energy crops (260-520 GJ ha À1 year À1 ), although agronomic suitability of specific candidate energy crops would need to be evaluated and confirmed.
