“…Additionally, the impacts of biodiesel can be evaluated by environmental life cycle assessment (LCA), which is outlined by the International Organization of Standardization's 14040 series [16]. Most LCA studies of biodiesel have focused on environmental impacts of biodiesel derived from different bioresources, e.g., soybean, rapeseed, and algae [17][18][19][20][21]. The effects of algae-derived biodiesel used in the passenger cars could be net positive or negative, depending on the algae cultivation and conversion processes from algae to biodiesel [18].…”

Houston, the fourth largest metropolis in the US, currently experiences severe air pollution. Major pollutants, such as VOCs, CO, NO , PM, SO , CH 4 , and CO 2 , are released from the transportation fleets. To decrease fossil fuel use and greenhouse gas emissions from fleet vehicles, more and more biodiesel is used in vehicles in the Houston metropolis. The GREET model was used for simulating the fuel cycle emissions of diesel vehicles using different biodiesel blends in Houston. The fuels examined were dieselbiodiesel blends of B0, B5, B20, B50, B80, and B100. The energy and water use and emissions from vehicles fueled with the blends were investigated. The study shows that the reductions in GHG emissions are significant at the Well-to-Pump stage, and all the emissions, except GHGs and NO , reduce at the Pump-to-Wheel stage. The overall Well-to-Wheel analysis shows that biodiesel is beneficial for both passenger cars and heavy duty trucks. However, the benefits are more pronounced for passenger cars compared to heavy duty vehicles. When 50% of diesel passenger cars and HDDTs are switched to B20 in the Greater Houston area in 2025, the daily GHG emissions will be reduced by 2.0 and 712.1 CO 2 -equivalent tonnes, respectively.

“…It is, finally, remarked that while optimal design is a widely adopted methodology in view of techno-economic analysis of renewable power sources since a few years [31], life cycle aspects are being investigated with a certain degree of accuracy in this respect only recently [32,33]. The authors also remark that a complete procedure for the design optimization dealt with in the paper requires the solution of a parameter identification issue for the battery modeling.…”

Probabilistic Battery Design Based upon Accelerated Life Tests

et al. 2016

A probabilistic battery design method is discussed in the paper, with reference to lithium-ion batteries, based upon battery lifetime and related economical aspects. The method takes into account the dependence of battery lifetime on different parameters, such as design maximum specific power and operating environment. The methods relies on a large set of experimental measurements, in particular accelerated life tests. In addition, the randomness of the above parameters in real operating conditions is considered in the paper. Based on available experimental data, the lifetime probability distribution of these batteries has been estimated by means of a Weibull model. More specifically, after a thorough statistical data analysis, a probabilistic method for battery design is proposed which ensures the minimization of a suitable cost function which has the expected lifetime as a basic input. The method allows to guarantee the required robustness design against the random variations in specific power experienced by a lithium ion battery designed for a small electric bus (public transport service).

“…Life cycle assessment studies have previously concluded that producing algal biomass with the sole intent of using the accumulated lipids (or starch) for biofuel production is not environmentally (Gnansounou and Raman 2016) or economically (Soratana et al 2014) advantageous. Thus, production and recovery of higher value products like fine chemicals, carotenoids, and therapeutic recombinant proteins along with lipids can promote commercialization.…”

Microalgae biomass has garnered significant attention as a renewable energy feedstock and alternative to petroleumbased fuels. The diverse metabolism of green microalgae species additionally provides opportunities for recovery of products for feed, food, nutraceutical, cosmetic, and biopharmaceutical industries. Recently, the concept of using microalgae as part of a biorefinery model has been adopted in place of refinery methods focused on recovering one target product. This has led to producers exploring co-production of high value and high volume products in an effort to improve process economics. With numerous potential products and applications, the biomass source or specific strain must be carefully selected to accumulate extractable levels of the target molecule(s). It is additionally imperative to understand the morphology and metabolism of the selected strain to cost-effectively manage all stages of commercial production. This review will focus specifically on microalgae in the division of Chlorophyta, or green algae and their extracellular matrices (ECM), potential for commercial products, and finally describe a holistic approach for biomolecule extraction and recovery. Additionally, cell disruption and fractionation methods for recovery of biomolecules for commercial products are highlighted along with an alternative method, aqueous enzymatic processing for multiple biomolecule extraction and recovery from green microalgae. An emphasis is placed on connecting the morphological characteristics of microalgae ECM or organelle membranes to implications on separation and purification technologies.
