The COVID‐19 pandemic presented a chance to investigate the effects of system‐wide emergencies on major global commodities such as water and energy. In terms of environmental policies and attaining supply security, these developmental goals are interrelated. Despite pandemic disruptions, there is a compelling need for a systematization in these areas for the transition to clean water access and sustainable energy. This article presents a comprehensive assessment of the effects of COVID‐19 on these two sustainable development goals. Further, an integrated aspect of water and energy access for sustainable development is evaluated with insights on the effects of COVID‐19 on the water‐energy nexus. Additionally, technological evolution for building better water and energy supply systems is presented. An insight into developing robust healthcare systems and how the water and energy SDGs affect population dynamics is also speculated, which indicates varied short‐term adaption experiences, and highlights the need for a re‐evaluation of the water‐energy nexus. The integrated solutions contributing to stability of the water supply chain, energy storage, and policy making during and after an outbreak are critical to achieving developmental goals.

Replacement of conventional hydrometallurgical and pyrometallurgical process used in E-waste recycling to recover metals can be possible. The metallurgical industry has been considered biohydrometallurgical-based technologies for E-waste recycling. Biorecovery of critical metals from phosphor powder from spent lamps is an example of transition to a bio-based circular economy. E-waste contains economically significant levels of precious, critical metals and rare-earth elements (REE), apart from base metals and other toxic compounds. Recycling and recovery of critical elements from E-waste using a cost-effective technology are now among the top priorities in metallurgy due to the rapid depletion of their natural resources. This paper focuses on the perceptions of recovery of REE from phosphor powder from spent fluorescent lamps regarding a possible transition toward a bio-based economy. An overview of the worldwide E-waste and REE is also demonstrated to reinforce the arguments for the importance of E-waste as a secondary source of some critical metals. Based on the use of bioprocesses, we argue that the replacement of conventional steps used in E-waste recycling by bio-based technological processes can be possible. The bio-recycling of E-waste follows a typical sequence of industrial processes intensely used in classic pyro- and hydrometallurgy with the addition of bio-hydrometallurgical processes such as bioleaching and biosorption. We use the case study of REE biosorption as a new technology based on biological principles to exemplify the potential of urban biomining. The perspective of transition between conventional processes for the recovery of valuable metals for biohydrometallurgy defines which issues related to urban mining can influence the mineral bioeconomy. This assessment is necessary to outline future directions for sustainable recycling development to achieve United Nations Sustainable Development Goals. Graphical Abstract

“…Furthermore, concentrating on tailored policy mixes could be the most effective way to meet socio‐technical needs and accelerate the shift to a green hydrogen economy. Bose et al 34 studied aspects of bioeconomy and microbial fuel cell technologies for sustainable development and discovered that renewable energy is inextricably tied to carbon capture and storage, and bioenergy is a technology that will play a vital role in fulfilling sustainable development goals in the coming decade.…”

We present an experimental investigation on a proton battery, that could run both as electrolyser and fuel cell, using six different flow channel orientations viz. pin‐type, parallel, interdigitated, spiral, serpentine, and parallel serpentine. The battery stores energy in the form of hydrogen ions and its performance is determined in terms of hydrogen wt. % stored in an integrated carbon‐based electrode. In this paper, the fabrication of electrode, development of an experimental proton battery and its testing are disclosed. The characterization of the employed activated carbon electrode is done using scanning electron microscopy, X‐ray diffraction analysis, energy dispersive spectroscopy, and fourier transform infrared spectroscopy. The fabricated proton battery is tested by charging (E‐mode operation) and discharging (FC‐mode operation) subsequently at normal temperature and pressure conditions. In the E‐mode operation, electrochemical hydrogen storage of the battery with six different flow channels is found to be in the range of 1.36–1.97 wt. %. The corresponding desorption of hydrogen in the FC‐mode operation is found to be in the range of 1.047–1.479 wt. %, respectively, for six different flow channels. The comparative result analysis revealed that parallel serpentine flow channel outperformed, with energy storage capacity of 1.97 wt. %; and pin type channel design showed comparatively low performance with energy storage capacity of 1.36 wt. %. The presented research work is an effort towards meeting the set targets of hydrogen storage set by the U.S. Department of Energy to make the hydrogen technology commercially viable. Statement of Industrial Relevance The presented research work has relevance with the power industry as it reveals the optimum design of flow channels for enhanced hydrogen adsorption. It is a way forward towards developing a fuel‐cell based proton battery that does not emit harmful fumes like lithium batteries and therefore, is environmentally friendly. Novelty or Significance The presented research work is a maiden attempt of testing different designs of micro‐flow channels in an experimental proton battery that is a single unit capable of performing dual tasks i.e., electrolyser and fuel cell to store energy and give out power when required.
