“…The liquids can directly replace petroleum products for heating and electricity purposes and some chemical compounds. The replacement of some other chemicals and transportation fuels requires an additional upgrading step, in which the quality of the bio-oil/biocrude is elevated to the higher requirements of those products [84][85][86]. The bio-oil produced by these technologies can be used to replace petroleum in other markets as well.…”

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.

The economics of producing sustainable aviation fuel: a regional case study in Queensland, Australia

The airline industry has a strong interest in developing sustainable aviation fuels, in order to reduce their exposure to increasing oil prices and cost liability for greenhouse gas emissions. The feasibility and cost of producing sustainable biomass-based jet fuels at a sufficient scale to materially address these issues is an enormous challenge. This paper builds directly on the biophysical study by H.Rye, In review, which examined a 25 year scale-up strategy to produce 5% of projected jet fuel demand in Australia in 2020 (470 mL) in the Fitzroy region of Queensland, Australia. The strategy was based on the use of a mixed ligno-cellulosic biomass feedstock and assumed, for the sake of exploring and quantifying the scenario, a simplified two-step conversion processconversion of biomass to crude bio-oil within the region, and upgrade to jet fuel at a central Brisbane facility. This paper provides details on the costs of production in this scenario, focusing on two different strategies for biomass utilization, and two types of novel small-medium scale conversion technologies. The cost analyses have taken into account technology learning curves, different economies of scale and key cost sensitivities. The cost of biomass-based jet fuels is estimated to be between 0.70 and 1.90 $ L À1 when the efficiency of conversion of biomass to biocrude and subsequently to aviation fuel is varied by AE10% of published values, with an average value of 1.10 $ L À1. This is within the range of the projected 2035 conventional jet fuel price of 1.50 $ L À1 . Therefore, biomass-based jet fuel has the potential to contribute to supply of Australia's jet fuel needs in the future.

“…These impurities must be removed by a magnetic and a stone separator amongst others as they put the pyrolysis plant at risk; plant components, like feeding screws or the bucket elevator, could plug up. The water content of biomass should be less than 10 to 15 wt.% to achieve efficient operation of the plant and a higher‐grade product …”

For the production of alternative fuels, biogenic residues and waste materials were thermochemically converted by fast pyrolysis in a joint project between the Deutsches Biomasseforschungszentrum (DBFZ) and the Karlsruhe Institute of Technology (KIT). Biogenic residues and wastes which are not used so far or which could be utilized more efficiently were studied to add to the line of feedstock for future thermochemical applications. Project work includes the investigation and selection of possible residual feedstock and its potential, conversion of several feedstocks (e.g. different varieties of straw, hay, waste wood, bark, driftwood) by fast pyrolysis, and energetic use of the products to generate electricity and heat. An ecological and economic evaluation was conducted for an integral view of the process and feedstock utilized. Besides research and experimental activities of the project, a database on biomass pyrolysis tests has been established for public use. © 2013 Society of Chemical Industry and John Wiley & Sons, Ltd
