Liquid bio-oil from pyrolysis has the potential to contribute significantly to the liquid biofuel supply and as a source of a number of valuable chemicals. However, many challenges Czernik and Bridgwater, need to be overcome that include plant scale up, cost reduction, better oil stability and quality, norms and standards for producers and users, environmental health and safety issues in handling, transport, and usage.
Algal biofuels have the potential to strongly contribute to the bioenergy and biofuel industry. Major advantages are their relatively high yield and the lack of competition e. Research should focus on mobile, modular, and cost-effective systems for the cultivation and production of algae locally as the resources tend to distribute over a wide range. Research and development to find the best catalytic technology and efficient reactor design should continue for the so far proven most effective methods of fermentation of microbial to bioethanol fuel and the production of biodiesel via in situ transesterification of microalgal biomass.
A real challenge is finding breakthrough technology for realizing the metabolic engineering of photosynthetic organisms to enhance biofuel production.
Besides the technologies discussed above, the anaerobic digestion also holds a promise for a potentially significant contribution to future bioenergy and biofuel production. The anaerobic digestion research should continue on the search for efficient and cost-effective integrated systems to produce bioenergy methane and biofertilizers from organic feedstocks, including purpose-grown energy crops, microalgal biomass, crop residues, food and animal waste, and other organic materials. Anaerobic digestion is a highly complex process that involves immeasurable quantities of biological and chemical reactions all taking place simultaneously.
There is a need to increase the scientific understanding of the biological and physiochemical reactions and interactions in a digester. For example, the normal operation of a digester requires the balance of reactions between chemicals and microorganisms which can be lost simply due to the presence of inhibiting agents and toxins. Consequently, the identification of the toxic and inhibiting substances in the reactor and their interactions with the chemicals and microorganisms during the digestion process is critical for the productive operation of the plant.
Engineering approaches toward the optimal design of the reactor and the process are also important.
The Energy crisis, air pollution, and greenhouse gases have become the driving force in the shift toward cleaner and renewable fuel alternatives. Biomass is an excellent candidate fuel source as its resource development and production processes impact minimally on the food chain, water supply, land use, and environment. Most importantly, biomass energy can be considered carbon-neutral.
However, in the challenge for making biofuels a legitimate candidate, the focus should be placed on a clear understanding of the energy policy, environmental impacts, emission characterization, and Life Cycle Assessment LCA associated with the use of biomass for energy.
Summary. The newest addition to the Green Chemistry and Chemical Engineering series from CRC Press, Biofuels and Bioenergy: Processes. The newest addition to the Green Chemistry and Chemical Engineering series from CRC Press, Biofuels and Bioenergy: Processes and Technologies provides .
These can be accomplished through:. Utility regulators, service providers, and customers must make critical, long-term decisions in an ever-changing environment due to regulations and laws driven by local, state, federal, and international government policies. Meeting the challenges in the energy industry posed by climate change policy will assuredly alter electric utility investment plans, drive regulators to adopt innovative policies, and impact customers in multiple ways. Similar concerns are associated with the transportation and manufacturing sectors. The issues of sustainability of bioenergy and biofuel are complex as the biomass infrastructure is huge and far-reaching, while the science and technology are just in their infancy.
However, the policies and regulations for the future establishment of the energy industry being made now create a challenge for scientists and engineers to communicate with policy decision makers.
Dale et al. It focuses on. As elaborated and discussed above, biomass, a carbon-neutral and renewable energy resource, holds a strong potential to provide a major solution to our future energy needs. However, this potential can only be realized through intense collaboration amongst stakeholders to pool available resources necessary to overcome obstacles and challenges. Chang, A.
