“…Hydrogen as an ideal secondary energy source, is mainly produced from another substance, referred to as primary energy, such as fossil fuels and renewable sources. [1,2] Steam reforming of methane (SRM) by far is the benchmark industrial process that has been employed for H 2 production, which contributes about 50 % of world's hydrogen amounts (Eq. 1).…”

Embedding Ni nanoparticles (NPs) into supports has been widely accepted as one of solutions for Ni confinement. Herein, we have adopted a method of preparing well-confined Ni NPs by precisely adjusting the reduction temperature of nickel contained phyllosilicates (PSi) materials to obtain Ni@PSi catalysts. H 2 reduction at 600 °C for Ni-PSi precursor was optimized to build the embedded structure with uniform Ni NPs (ca. 3.0 nm) incorporated into the well-maintained PSi structure. Such structure not only endowed the highest reaction rate for steam reforming of methane (SRM), but kept the stability well under the harsh reaction conditions of SRM. Either too high (850 °C) or too low (400 °C) reduction temperature which could not form such embedded structure led to a quick deactivation due to obvious sintering of Ni and coke deposition. The present study provides a more effective way of keeping Ni NPs from sintering in SRM.

“…The report defined sustainable development as "development that meets the needs of the present without compromising the ability of future generations to meet their own needs" [8] (p. 26). This definition has been used by research in the fields of renewable sources [9][10][11][12], mechanical engineering [13,14], agriculture [15], knowledge and innovation management [16][17][18][19][20], the environment [21][22][23], logistics [24], sustainable development [25][26][27][28][29], and innovations in the construction industry [30]. Sustainability is therefore a broad concept that has been used in a wide variety of fields, from human sciences to highly technological fields.…”

The increasing popularity of social media worldwide provides us with an opportunity to understand social, cultural, and environmental issues about people’s perception of sustainability. The article aims at identifying the main topics of communication related to hashtag # sustainability based on a communication analysis on the Twitter network. We investigated the perception of sustainability using data from 414,926 Twitter interactions by 223,476 users worldwide. The data were recorded between April 17, 2018 and July 12, 2019. We identified Innovation, Environment, Climate Change, Corporate Social Responsibility, Technology, and Energy as key hashtags in the field of sustainability. In conjunction with this, we identified the six following communities: (1) Environmental Sustainability, (2) Sustainability Awareness, (3) Renewable Energy and Climate Change, (4) Innovative Technology, (5) Green Architecture, and (6) Food Sustainability. The usage of these communities is applicable in marketing communication as well as in the Corporate Social Responsibility activities of the given companies. The results of the analysis give the organizations a possible direction for their sustainable business model improvement via the contribution of society´s voice.

Realising the Potential of Renewable Energy as a Tool for Energy Security in Small Island Developing States

et al. 2022

Small Island Developing States (SIDS) are heavily dependent on the use of imported fossil fuels to address their energy needs. This has a negative impact on the environment, SIDS budgets, and energy security. Therefore, this study aimed to investigate the role of renewable energy (RE) as a tool for energy security in SIDS. In this regard, using VOSviewer, a widely known software tool, two bibliometric analyses were performed with a focus on the literature that explores two intertwined issues: (i) the links between RE and energy security; and (ii) the implications of RE and energy security in SIDS. The results from the study show that RE can help SIDS enhance their energy security and assure long-term energy sustainability. In addition, the results show that with the reduction in the cost of batteries in the future, they will eventually replace diesel generators. Moreover, the study showed that renewable energy may assist SIDS in their long-term efforts to achieve food security. The analysis discusses the major obstacles and the potential solutions for the integration of RES into the energy generation of SIDS. The paper concludes with useful recommendations to help island nations reduce their carbon footprint.
