“…Chiaramonti et al [15] examined the possible routes for thermochemical conversion of microalgae into liquid biofuels, distinguishing between dry-processes (pyrolysis) and wet-processes (near critical-water hydrothermal liquefaction). Major engineering advantages and challenges for both processes are discussed in the paper.…”

“…However, some other research found that the typical HTL oil yield reported in several studies is equal to approximately 50–60% depending also on the use of homogeneous or heterogeneous catalysts . The bio‐oil from HTL contains approximately 10–20% of oxygen and nitrogen, with energy density in the range of 30–37 MJ kg −1 . Meanwhile, operated a continuous‐flow HTL reactor to decompose several different algae feedstocks at 350°C and obtained a crude bio‐oil yield around 38–64% .…”

Currently, fossil materials form the majority of our energy and chemical source. Many global concerns force us to rethink about our current dependence on the fossil energy. Limiting the use of these energy sources is a key priority for most countries that pledge to reduce greenhouse gas emissions. The application of biomass, as substitute fossil resources for producing biofuels, plastics and chemicals, is a widely accepted strategy for sustainable development. Aquatic plants including algae possess competitive advantages as biomass resources compared to the terrestrial plants in this current global situation. Bio‐oil production from algal biomass is technically and economically viable, cost competitive, requires no capacious lands and minimal water use and reduces atmospheric carbon dioxide. The aim of this paper is to review the potential of converting algal biomass, as an aquatic plant, into high‐quality crude bio‐oil through applicable processes in Malaysia. In particular, bio‐based materials and fuels from algal biomass are considered as one of the reliable alternatives for clean energy. Currently, pyrolysis and hydrothermal liquefaction (HTL) are two foremost processes for bio‐oil production from biomass. HTL can directly convert high‐moisture algal biomass into bio‐oil, whereas pyrolysis requires feedstock drying to reduce the energy consumption during the process. Microwave‐assisted HTL, which can be conducted in aqueous environment, is suitable for aquatic plants and wet biomass such as algae.

“…Biofuel produced by crops faces many problems such as low carbon acquisition efficiency, poor life cycle emissions and a requirement for large amounts of land and fresh water; all these have darkened the future of green fuel production . Environmental friendly aspects of algae‐derived bioenergy could circumvent such negative impacts of biofuel production from crops because algae‐based fuels offer a wide range of advantages; algal cultivation has developed with the benefits of faster assimilation of nutrients from waste effluent, year‐round production, and higher photosynthetic yield and these features allow cultivation of microalgae using non‐potable water resources and agricultural wastewater, Moreover, the production of energy‐rich compounds in algal cells could be enhanced using newly emerged genetic engineering tools. The potential of engineered algae to be used in low‐carbon strategies for biofuel production is summarized in Figure .…”

Human activities and resultant changes in global climate have profound consequences for ecosystems and economic and social systems, including those that are dependent upon marine systems. The increasing concentration of atmospheric greenhouse gases (GHGs) has resulted in gradual modification of multiple aspects of marine ecosystem properties such as salinity, temperature, and pH. It is well known that temporal and spatial variations in environmental properties determine the composition and abundance of different algal populations in a region. Within the present study the evidence for algal compatibility to changing environmental conditions is surveyed. The unique ability of algal communities to play a role in promotion of CO2 sequestration technologies, biorefinery approaches, as well as transition to CO2‐neutral renewable energy has gained traction with environmentalists and economists in a view to mitigation of climate change using algae. The next step is to re‐evaluate the assumption of a steady‐state oceanic carbon cycle and the role of biological activities in response to future climate changes.
