Resource Base for Biogas Production in Middle East

Resource Base for Biogas Production in Middle East | Energy Blog | Scoop.it
Anaerobic digestion (or biogas technology) is the natural biological process which stabilizes organic waste in the absence of air and transforms it into biofertilizer and biogas. It is a reliable t...
Salman Zafars insight:

A wide range of organic substances are anaerobically easily degradable without major pretreatment. Among these are leachates, slops, sludges, oils, fats or whey. Some wastes can form inhibiting metabolites (e.g.NH3) during anaerobic digestion which require higher dilutions with substrates like manure or sewage sludge.

Harnessing Energy from Biogas

Harnessing Energy from Biogas | Energy Blog | Scoop.it

Biogas is the ideal fuel for generation of electric power or combined heat and power. A number of different technologies are available and applied. The most common technology for power generation is internal combustion. Engines are available in sizes from a few kilowatts up to several megawatts. Gas engines can either be SI-engines (spark ignition) or dual fuel engines.

Salman Zafars insight:

The benefit of the anaerobic treatment will depend on the improvement of the process regarding a higher biogas yield per m3 of biomass and an increase in the degree of degradation. Furthermore, the benefit of the process can be multiplied by the conversion of the effluent from the process into a valuable product.

Thermal Conversion of Biomass

Thermal Conversion of Biomass | Energy Blog | Scoop.it
A wide range of technologies exists to convert the energy stored in biomass to more useful forms of energy. These technologies can be classified according to the principal energy carrier produced in the conversion process.
Salman Zafars insight:

Co-firing of biomass wastes with coal and other fossil fuels can provide a short-term, low-risk, low-cost option for producing renewable energy while simultaneously reducing the use of fossil fuels. Co-firing involves utilizing existing power generating plants that are fired with fossil fuel (generally coal), and displacing a small proportion of the fossil fuel with renewable biomass fuels.

Ethanol from Lignocellulosic Biomass

Ethanol from Lignocellulosic Biomass | Energy Blog | Scoop.it

Lignocellulosic biomass consists mainly of lignin and the polysaccharides cellulose and hemicellulose. Compared with the production of ethanol from first-generation feedstocks, the use of lignocellulosic biomass is more complicated because the polysaccharides are more stable and the pentose sugars are not readily fermentable by Saccharomyces cerevisiae. 

Salman Zafars insight:

The major cost components in bioethanol production from lignocellulosic biomass are the pretreatment and the enzymatic hydrolysis steps. In fact, these two process are someway interrelated too where an efficient pretreatment strategy can save substantial enzyme consumption. Pretreatment step can also affect the cost of other operations such as size reduction prior to pretreatment.

Biobutanol as a Biofuel

Biobutanol as a Biofuel | Energy Blog | Scoop.it
The major technical and commercial limitations of existing biofuels has catalyzed the development of advanced biofuels such as cellulosic ethanol, biobutanol and mixed alcohols.
Salman Zafars insight:

Biobutanol production is currently more expensive than bioethanol which has hampered its commercialization. However, biobutanol has several advantages over ethanol and is currently the focus of extensive research and development. There is now increasing interest in use of biobutanol as a transport fuel. As a fuel, it can be transported in existing infrastructure and does not require flex-fuel vehicle pipes and hoses. Fleet testing of biobutanol has begun in the United States and the European Union.

Biofuels from Lignocellulosic Biomass

Biofuels from Lignocellulosic Biomass | Energy Blog | Scoop.it
First-generation biofuels (produced primarily from food crops such as grains, sugar beet and oil seeds) are limited in their ability to achieve targets for oil-product substitution, climate change mitigation, and economic growth.
Salman Zafars insight:

Lignocellulosic biomass has an advantage over other agriculturally important biofuels feedstocks such as corn starch, soybeans, and sugar cane, because it can be produced quickly and at significantly lower cost than food crops. Lignocellulosic biomass is an important component of the major food crops; it is the non-edible portion of the plant, which is currently underutilized, but could be used for biofuel production.

Energy Potential of Bagasse

Energy Potential of Bagasse | Energy Blog | Scoop.it
Sugarcane is one of the most promising agricultural sources of biomass energy in the world. Sugarcane produces mainly two types of biomass, Cane Trash and Bagasse.
Salman Zafars insight:

For every 100 tons of Sugarcane crushed, a Sugar factory produces nearly 30 tons of wet Bagasse. Bagasse is often used as a primary fuel source for Sugar mills; when burned in quantity, it produces sufficient heat and electrical energy to supply all the needs of a typical Sugar mill, with energy to spare. The resulting CO2 emissions are equal to the amount of CO2 that the Sugarcane plant absorbed from the atmosphere during its growing phase, which makes the process of cogeneration greenhouse gas-neutral.
