In the midst of a climate crisis, alternative and low-carbon energy resources must be put to scale in order to achieve carbon emission reductions in the coming decades. In this respect, hydrogen has gained attention as an alternative energy carrier. Hydrogen can be produced from methods that are commonly classified by a range of colours. However, each hydrogen source has its own challenges in terms of energy security, energy equity, and environmental sustainability. This perspective offers insights about the critical role that Process Systems Engineering (PSE) will play in addressing these key challenges. We also present suggestions on possible future PSE studies in the area of the hydrogen economy.
Bioenergy with carbon capture and storage (BECCS) has been identified as the most viable and cost-effective technology to achieving the 1.5°C targets set down in the 2015 Paris Agreement. It is essential to understand the impact of BECCS on carbon dioxide removal at a commercial scale. As such, this research presents an extensive life cycle analysis and optimisation of BECCS. To ensure the proposed methodology is appropriate for this research, case study of three cases is performed. In the case study, an existing coal-fired power plant is used as a base case for comparison between 2 different BECCS configurations. A regional assessment of the BECCS configurations from various critical performance aspects is then performed. This consists of assessing the system effectiveness, environmental impacts, energy efficiency, and cost optimisation from a life cycle perspective.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
