“…Until a transition to the use of new clean sources of energy is eventually achieved, a possible option for reducing the impact of power generation from fossil fuels is the carbon capture and storage (CCS) from the flue gases. A review on several alternatives for this purpose can be found in [1]. Nevertheless, the main available techniques (pre-combustion carbon capture [2], post-combustion carbon capture [3] and oxy-combustion [4]) imply severe energy penalties related to de difficulty of separation of pure gases from a mixture of them.…”

Chemical-looping hydrogen generation (CLHG) is a chemical-looping combustion variant that allows simultaneous production of power and hydrogen. A thermodynamic analysis from the exergy method point of view of an integrated syngas-fueled CLHG cycle is carried out with the aim of contributing to the conceptual understanding and development of CLHG systems. The cycle working point is optimized in a range of conditions. The proposed system shows a very interesting potential for power, hydrogen and process heating coproduction with high efficiency.

“…The control of CO 2 feeding can be evaluated by pH measurements to minimize the loss of CO 2 . As a result, CO 2 fixation using microalgae can reduce the CO 2 emission from power plants, which has the positive environmental impact (Inoue et al, 1995;Yun et al, 1997;Abu-Khader, 2006;Brennan and Owende, 2010).…”

Fossil fuels, which are recognized as unsustainable sources of energy, are continuously consumed and decreased with increasing fuel demands. Microalgae have great potential as renewable fuel sources because they possess rapid growth rate and the ability to store high-quality lipids and carbohydrates inside their cells for biofuel production. Microalgae can be cultivated on opened or closed systems and require nutrients and CO 2 that may be supplied from wastewater and fossil fuel combustion. In addition, CO 2 capture via photosynthesis to directly fix carbon into microalgae has also attracted the attention of researchers. The conversion of CO 2 into chemical and fuel (energy) products without pollution via this approach is a promising way to not only reduce CO 2 emissions but also generate more economic value. The harvested microalgal biomass can be converted into biofuel products, such as biohydrogen, biodiesel, biomethanol, bioethanol, biobutanol and biohydrocarbons. Thus, microalgal cultivation can contribute to CO 2 fixation and can be a source of biofuels. This article reviews the literature on microalgae that were cultivated using captured CO 2 , technologies related to the production of biofuels from microalgae and the possible commercialization of microalgae-based biofuels to demonstrate the potential of microalgae. In this respect, a number of relevant topics are addressed: the nature of microalgae (e.g., species and composition); CO 2 capture via microalgae; the techniques for microalgal cultivation, harvesting and pretreatment; and the techniques for lipid extraction and biofuel production. The strategies for biofuel commercialization are proposed as well.

“…Thus it is crucial to optimize the amount of gas flow rate for highest CO 2 fixation rate. Optimization of gas flow rate on flue gas had never been done before, previous studies only concern on the CO 2 concentration [11]. From the optimization 3D response surface and 2D contour plots, the optimum condition was achieved at 0.15L/min.…”

As concerns over global warming are increasing, a great deal of research on carbon capture has been carried out. Among various CO 2 utilization technologies, biological methods -particularly ones using microalgae photosynthesis -have several advantages. This natural means of capturing emitted CO 2 through photosynthetic microalgae, while producing some value-added by-products, can be regarded as economically viable and more sustainable. In this study, marine microalgae Isochrysis sp. was cultured using a 2x10-L customized bubble column photobioreactor skid to determine the optimum operating condition (pH, temperature, gas flow rate and luminance) towards highest carbon fixation rate. Twenty-one experimental runs were carried out in a lab-scaled photobioreactor supplied with simulated flue gas, containing O2, SO 2 , NO 2 , CO 2 and CO. Illuminance is available through units of Philip's T5 type fluorescent bulb with timer-control. Automatic data logging was made possible through Dewetron's DEWE 43 data acquisition system. A carbon fixation ability calculation was made by comparing the gained dry weight between first and last days, taking into account the approximate biomass molecular weight in the photosynthesis reaction. Design of the experiment and optimization analysis was carried out using Design Expert Software 8.0. Results indicate that experimental simulations with temperatures of 300°C, pH 7.5, luminance of 1500 lux and a 0.15 liter/min gas flow rate give the highest fixation rate of 3.68 g CO2/day. Thus, this finding shall be useful in utilizing the capabilities of Isochrysis sp. as the biological carbon fixer in neutralizing carbon emissions from power plants.
