culture or Microalgae as an Ideal biomass? Or Microalgae: advantages and disadvantages The microalgae culture have the infinite potential to be used as primary producers of biomass in coming years, eventually they will turn out to be as most significant energy source. They can act as feedstock for several types of renewable fuels such as ethanol, methanol, biodiesel, methane and hydrogen. Table 1 represents certain feedstocks used for biofuel production (Chisti 2007; Dominguez-Faus et al., 2009; Mata
are not used for food or feed, and are specifically called lignocellulosic biomass.[2] As an energy source, biomass can either be used directly via combustion to produce heat, or indirectly after converting it to various forms of biofuel. Conversion of biomass to biofuel
Title: Biofuel, is it the future energy solution? 3. Is biofuel the answer? - Analysis of pros and cons Pros : 1- Availability of Biofuels Biofuels are theoretically unlimited. In terms of availability, biofuels have a big advantage as they are at the top of the list of alternatives. The transition is likely to be subtle but slow as more and more fossil fuel is replaced with biofuel. 2- Environmental Impact Biofuels are environmentally friendly if they’re carefully produced and distributed
ester which is the fuel. STEP 3: The left biomass goes for pyrolysis process at a temperature range of 500-600 degree Celsius in the absence of air and then condensed by temperature change. The process then uses algae in its original state to create biofuel. After the process occurs only product is gas, char and fuel. -Gas can be reused as a resource somewhere else. - char can be used as an organic fertilizer or fuel. 2. ALTERNATE USE OF BEADS: - The beads containing bacteria and algae is dehydrated
technique of CO2 sequestration. In view of this, microalgae have been identified as a candidate for sequestering CO2. Besides mitigating CO2, they may be recognized to have numerous different makes use of. They can be used for the manufacturing of biofuels (e.g. biodiesel, bioethanol, biohydrogen) and different crucial merchandise like business biofilters, food products and secondary metabolites
While combustion of biomass is the most direct and technically easiest process, the overall efficiency of generating heat from biomass energy is low. Gasification has many advantages over combustion. It can use low-value feed-stocks and convert them not only into electricity, but also into transportation fuels. In the upcoming years, it will serve as a major technology for complementing the energy needs of the world [4]. Use
BIOFUELS Two problems roused the world’s concern in recent years. One is energy crisis caused by the squandering of petroleum fuel. Second problem is environmental problems such as greenhouse effect, global warming, etc. To deal with such problems, renewable sources, utilization technology and bioenergy production technology have been developed. Bioethanol as one of the biofuel can be blended in different proportions in automobiles with gasoline. Biobutanol is also a new biofuel (Liu, Wang, & Zhang
Energy is a form of life in the living. Thus, people have the tendency to lose its ability to do things as energy depletes. As a result, the needs of energy are often crucial, energy crisis may occur due to the scarcity of resources and the growth in energy demand. Since Brunei Darussalam is well-provided with conventional energy resources such as oil and gas, the probability of energy crisis occur in Brunei is lessened, but, it does not indicate that it would not happen in Brunei. As Brunei is enriched
whenever it is needed and they are non-exhaustive.1 Whereas, non-renewable energy sources include natural gas, coal, oil and nuclear energy which are generated from ancient animal or plant remains or fossils and they are exhaustive. The major advantage of non-renewable energy sources is that they are readily available, easy to use and also economical to transform one non-renewable energy type to another. On the other hand, the most important disadvantage of non-renewable energy sources is that
waste, etc. Recently research is going in agricultural production of energy crops which should be of high yield and low maintenance like corn, sugarcane, switch grass, hemp, willow, palm oil, etc. Also there is a production of a liquid or gaseous biofuel which includes capture of landfill methane also bioethanol from fermentation, often from corn. Cellulosic bioethanol is usually from a grass. Carbon leaking can increase level of CO2. Sequestration in soil can result in a net decrease in CO2
