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.

TL;DR: In this paper, three major technologies that are utilised for carbon capture are evaluated: pre-combustion, post combustion and oxyfuel combustion, and they compare carbon uptake technologies with techniques of carbon dioxide separation.
Agricultural waste management strategies for environmental sustainability.
TL;DR: The main component of the crop residue and agro-industrial waste is cellulose, followed by lignin and hemicellulose (lignocellulosic biomass), which can also serve as a sustainable source of biofuel and bioenergy in order to mitigate the fossil fuel shortage and climate change issues as mentioned in this paper.

Solar hydrogen production via alkaline water electrolysis
TL;DR: In this paper, the authors presented a system for hydrogen production via water electrolysis using a 960 Wp solar power plant, where the results obtained from the monitoring of photovoltaic modules mounted in pairs on a fixed, a single-axis and a dual-axis solar tracker were examined to determine if there is a possibility to couple them with an electrolyzer.
