Abstract
Energy is a fundamental element supporting societal development, particularly with the increasing dependency on the Internet of Things. It is also the main contributor to environmental impacts and subsequently, a potential sector for mitigation. Sustainable energy system design considers energy savings and energy efficiency, waste and consumption reduction, process efficiency enhancement, waste heat recovery, and integration of renewable energy. Emerging tools range from advanced Process Integration, modelling, simulation, and optimisation, to system analysis and assessment. This review covers selected emerging studies promoting sustainable system design, including the recent developments reported in the Special Issue (SI) of the 22nd Conference on Process Integration, Modelling and Optimisation for Energy Saving and Pollution Reduction (PRES’19). The primary emphasis was to enhance the economic and environmental performance. However, social factors were also highlighted as essential for future sustainable development. The discussion and analysis in this review focus on the most recent developments of (a) heat integration and heat transfer; (b) integrated and newly developed heat exchangers, (c) integration of renewables, and (d) roles in economic and environmental sustainability. The key results are highlighted, and future research ideas are suggested according to their links to a broader context.
Highlights
Energy is a fundamental social need and plays an essential role in driving economic growth.The emerging economy requires the support of a reliable, affordable, and energy system with low carbon emissions and air pollutants
The aim of this study is to review the emerging tools for sustainable system design, including the recent developments reported in the Special Issue (SI) of PRES 2019
The results showed that up to 40% of the natural gas could be replaced by syngas of biogenic origin, while still achieving satisfactory thermal efficiency and temperature characteristics
Summary
Energy is a fundamental social need and plays an essential role in driving economic growth. IEA [29] highlighted that the energy industry that emerges from COVID-19 would change significantly, given an expectation of a reduction in investment This could inhibit sustainable development because energy is likely to be affected first. Is one contributor who highlighted the need for scientific research into the quantification of actual environmental impacts This is because a highly implemented circular economy progresses toward sustainability features. Various works that aspire to promote sustainable system design by addressing the issues of enhancing energy and environmental performance were presented in the Special Issue (SI) of the 22nd Conference on Process Integration, Modelling and Optimisation for Energy Saving and Pollution Reduction (PRES’19). The energy system design tools that are considered in this study are summarised, including modelling, simulation, optimisation, and analysis or assessment.
