Clean hydrogen generation and storage strategies via CO 2 utilization into chemicals and fuels: A review

“…Therefore, the conversion of CO 2 and clean H 2 from renewable resources for market scale of alcohol such as methanol and ethanol is potentially extensive . Since CO 2 conversion in early stages, there are some opportunities due to the usage of nontoxic, noncorrosive, and nonflammable reactant that can easily be stored in liquid form under mild condition.…”

Energy and CO2 management for chemical and related industries: issues, opportunities and challenges

“…An important issue to note in Fig. 3 is that energy efficiency plays a major role, which also affects the process sustainability in terms of reduced operating cost, reduced environmental impact and reduced waste [2]. Therefore, research needs to be focused on technologies that can provide energy efficiency improvements through sustainable process engineering and the adoption of energy management systems and practices with the goal of energy demand reduction as well as meeting these demands with more sustainable energy supply.…”

“…Therefore, they are under-utilized for industrial needs. Table 1 gives a list of known resources of energy along with their levels of utilizations (adopted and extended from Vooradi et al [2]) as well as perspectives/remarks related to their utilization. With the various sources of energy available, the challenge is to reduce the utilization of fossil-based resources and to increase the non-fossil-based sources, capture and sequestrate or utilize the captured CO 2 , and reduce the energy demand.…”

“…Recently, Vooradi, et al [2] provided a detailed overview of the different types of energy resources versus their current levels of consumption, while Gani et al [3] highlighted some perspectives on how to manage the process energy demands versus CO2 emissions in a short conference proceedings paper Using these developments as the basis, this paper further extends the discussion with additional data on industrial energy utilization versus CO 2 emission and, analysis related to new developments in the area of synthesis-design of more sustainable chemical and related processes. In particular, use of techniques such as process intensification, process integration and energy integration at different levels, that aims to minimize the energy consumption (demand) and prevent the pollution problem rather than cure it after the incident has occurred, are highlighted.…”

A Facile Fabrication of Supported Ni/SiO2 Catalysts for Dry Reforming of Methane with Remarkably Enhanced Catalytic Performance

“…Among the most widely investigated technologies, there are comparable advantages associated with the dry reforming of CH 4 (DRM) with CO 2 for producing syngas [13]. On the one hand, compared to the other reforming processes, there is a 20% lower operating cost for DRM [14]; on the other hand, the reforming of CH 4 using CO 2 not only produces high purity syngas [15,16] but also reduces the emissions of two abundantly available greenhouse gases to alleviate global climate change [17][18][19][20].…”
