Abstract
The ever-increasing world energy demand drives the need for new and sustainable renewable fuel to mitigate problems associated with greenhouse gas emissions such as climate change. This helps in the development toward decarbonisation. Thus, in recent years, hydrogen has been seen as a promising candidate in global renewable energy agendas, where the production of biohydrogen gains more attention compared with fossil-based hydrogen. In this review, biohydrogen production using organic waste materials through fermentation, biophotolysis, microbial electrolysis cell and gasification are discussed and analysed from a technological perspective. The main focus herein is to summarise and criticise through bibliometric analysis and put forward the guidelines for the potential future routes of biohydrogen production from biomass and especially organic waste materials. This research review claims that substantial efforts currently and, in the future, should focus on biohydrogen production from integrated technology of processes of (i) dark and photofermentation, (ii) microbial electrolysis cell (MEC) and (iii) gasification of combined different biowastes. Furthermore, bibliometric mapping shows that hydrogen production from biomethanol and the modelling process are growing areas in the biohydrogen research that lead to zero-carbon energy soon.Graphical
Highlights
The depletion of fossil-based fuel sources along with their increasing use day by day has created big concerns related to greenhouse gas (GHG) emissions and global warming
Through bibliometric mapping, we suggest steps and future guidelines from the gaps in the literature for the optimisation of hydrogen production from organic waste streams
Fermentation can be defined as the process of energy generation involving an endogenous electron acceptor from the oxidation of organic waste materials using a number of different microorganisms
Summary
The depletion of fossil-based fuel sources along with their increasing use day by day has created big concerns related to greenhouse gas (GHG) emissions and global warming. The concept of using waste materials from different biological sources to produce environment-friendly biohydrogen can be potentially helpful to tackle the ongoing environmental challenges, while for all H2 production processes (NG reforming, biomass and coal gasification, water electrolysis and others), there are requirements for better reliability and operating flexibility, a reduction in the capital costs and a significant enhancement in the plant efficiencies [17]. Through bibliometric mapping, we suggest steps and future guidelines from the gaps in the literature for the optimisation of hydrogen production from organic waste streams Overall, this critical review is aimed at helping the academics working in the biohydrogen production research area along with the industrial application and roll-out of a zero-carbon economy. It will focus on themes that face the development and potential transformation of the biohydrogen market and its future
