“…Seawater contains a lot of natural inorganic and organic matter that can be used indirectly to produce biofuel through microbial or seaweed cultivation. Microorganisms such as phototrophic bacteria, cyanophytes, and dark-acidogenic bacteria can grow in seawater, producing H 2 and/or VFAs [64][65][66][67]. Furthermore, phototrophic bacteria have the potential to degrade VFAs for H 2 production [68].…”

Fossil fuel depletion, climate change, and increased global energy demands are the driving forces to find alternative sources of energy. Marine-based biorefinery has been recently discussed as a promising route to mitigate the environmental challenges, enhance the energy recovery, and provide a potential source for value-added products. Anaerobic digestion is a promising technology that can convert the organic compounds of marine ecosystems into biogas. To date, a comprehensive review incorporating integrated biogas potential and effective approaches to enhance seaweed digestibility for biogas production from marine resources has not been reported. Thus, the present review aims to explore and comprehensively present seaweed and other marine resources for potential biogas production. The basics and challenges of biogas production from seaweed are elucidated. The impact of biochemical composition on biogas and the microbial communities involved in anaerobic digestion of seaweed are discussed. Utilization of different techniques such as pretreatment, co-digestion, and sequential extraction of seaweed biomass to enhance the biogas yield and to mitigate the effect of inhibitors are presented. Specifically, this article evaluates the co-digestion of seaweed with other biomass feedstocks or liquid biowastes. Integration of marine microalgae cultivation on anaerobic digestate for value-added compound production, biogas upgrading, and bioenergy recovery provides a promising approach towards a zero-waste marine-based system.

“…Micro-organisms such as cyanobacteria, phototrophic bacteria, and dark-acidogenic bacteria have the ability to produce H 2 via fermentation of organic matter in seawater. These micro-organisms can break down the organic matter into H 2 and volatile fatty acids (VFA). − Among them, phototropic bacteria have the only ability to further degrade the VFA to form H 2 and CO 2 . The fermentation reactions are carried out in the presence of essential nutrients related to the specific micro-organism.…”

Energy security coupled with the impact of greenhouse gas emissions have resulted in growing interest in investigating new technologies for renewable energy production as an alternative to fossil fuels. In this context, seawater is an inexhaustible and environmentally benign source for the production of clean energy. Natural seawater is the most convenient medium to produce energy, when compared to synthetic seawater or fresh water. To date, there have been no detailed reviews regarding energy conversion methods using seawater. The main aim of this review is to furnish the important features of energy production/conversion technologies using seawater as a medium. The basic principle, application and important finding of the available technologies such as photocatalysis, photoelectrochemical, microbial desalination, biochemical, electrolysis, reverse electrodialysis, capacitive mixing, pressure retarded osmosis, mixing entropy battery, and seawater batteries have been described in this review. Energy or energy carriers can be produced in the form of electricity, hydrogen (H2), methane (CH4), and biodiesel. Relevant design and operating conditions that influence the energy production from seawater such as physicochemical properties of materials, reaction conditions, reactor design, and formation of byproducts are summarized briefly. We also found that most of the technologies have been evaluated only at the laboratory scale. To avoid the fouling problems, it is advised to use natural seawater after filtration.
