Storage Systems for Biomass - Cleantech Solutions

Storage Systems for Biomass - Cleantech Solutions | Energy Blog | Scoop.it

Sufficient storage for biomass is necessary to accommodate seasonality of production and ensure regular supply to the biomass utilization plant. The type of storage will depend on the properties of the biomass, especially moisture content. For high‐moisture biomass intended to be used wet, such as in fermentation and anaerobic digestion systems, wet‐storage systems can be used, with storage times closely controlled to avoid excessive degradation of feedstock.

Energy Partnership in South Asia - Cleantech Solutions

Energy Partnership in South Asia - Cleantech Solutions | Energy Blog | Scoop.it

South Asia has an interesting mix of countries displaying diversity in terms of natural resources, landscape, per capita income, culture, happiness index, etc. On the energy front all these countries today are facing a multitude of challenges in meeting their rapidly growing requirements in a sustainable manner. While governments of each of these countries have been trying to do their best, there are still shortages in terms of access, availability, and quality of supply. For example, not long ago, Pakistan’s power supply situation was more than satisfactory with a surplus supply of electricity, while India was a sink for electricity in the region. While India continues to suffer from perennial electricity shortages, Pakistan is now faced with a serious energy crisis, less than a decade since its surplus scenario in the early 2000s.

Salman Zafars insight:

Mycorrhizal fungi forms association with a lot of plant roots and studies have shown that they help plant nutrient and water uptake as well as help in increased pathogen and disease resistance. MF can be applied to plants where soil conditions are poor (ectomycorrhizal) or where there is a high risk of plant pathogens usually associated with vegetables and ornamental plants (AMF) or phytobial remediation of land.  AM fungi  esp glomus spp. are also used as bio-ameliorators of saline soils. With these immense benefits of MF it is sad to see that MF has not been widely used successfully on a global scale even with widespread public concern about the use of pesticides and other chemical agents.

Benefits of Anaerobic Digestion - Cleantech Solutions

Benefits of Anaerobic Digestion - Cleantech Solutions | Energy Blog | Scoop.it
Anaerobic digestion is the natural biological process which stabilizes organic waste in the absence of air and transforms it into biofertilizer and biogas.
Salman Zafars insight:

Anaerobic digestion is particularly suited to wet organic material and is commonly used for effluent and sewage treatment.  This includes biodegradable waste materials such as waste paper, grass clippings, leftover food, sewage and animal waste. The exception to this is woody wastes that are largely unaffected by digestion as most anaerobic microorganisms are unable to degrade lignin. Anaerobic digestion provides a variety of benefits which may be classified into three groups viz. environment, economic and energy

Introduction to Biomass Pyrolysis

Introduction to Biomass Pyrolysis | Energy Blog | Scoop.it

Pyrolysis is the thermal decomposition of biomass occurring in the absence of oxygen. It is the fundamental chemical reaction that is the precursor of both the combustion and gasification processes and occurs naturally in the first two seconds. The products of biomass pyrolysis include biochar, bio-oil and gases including methane, hydrogen, carbon monoxide, and carbon dioxide.

Depending on the thermal environment and the final temperature, pyrolysis will yield mainly biochar at low temperatures, less than 450 0C, when the heating rate is quite slow, and mainly gases at high temperatures, greater than 800 0C, with rapid heating rates. At an intermediate temperature and under relatively high heating rates, the main product is bio-oil.

America’s Oil Independence and Energy Beets

America’s Oil Independence and Energy Beets | Energy Blog | Scoop.it

The Energy Sugar Beet even out performs the EPA and DOE standards mandating crops to be considered for advanced biofuels meet a 50% reduction in GHG threshold. The new beet far out reached that 50% and comes in at 70% GHG reduction and that is using traditional farm practices. But in studies, using non-traditional practices such as low-till and the use of biodiesel on the farms this number has moved to over 80% GHG reduction range. With corn at an all time high, food vs. fuel issues still being debated and the price of gas going up daily, ethanol from Energy Beets will be the lowest priced fuel on the market.

Salman Zafars insight:

Conventional combustion technologies raise steam through the combustion of wastes. This steam may then be expanded through a conventional turbo-alternator to produce electricity. Fluidized bed combustors (FBC), which use a bed of hot inert material such as sand, are a more recent development. Bubbling FBCs are generally used at 10-30 MWth capacity, while Circulating FBCs are more applicable at larger scales.

What is Composting - Cleantech Solutions

What is Composting - Cleantech Solutions | Energy Blog | Scoop.it

The composting process is a complex interaction between the waste and the microorganisms within the waste. The microorganisms that carry out this process fall into three groups: bacteria, fungi, and actinomycetes. Actinomycetes are a form of fungi-like bacteria that break down organic matter. The first stage of the biological activity is the consumption of easily available sugars by bacteria, which causes a fast rise in temperature. The second stage involves bacteria and actinomycetes that cause cellulose breakdown. The last stage is concerned with the breakdown of the tougher lignins by fungi.

A Primer on Biodiesel | Energy Blog | Scoop.it
Biodiesel is a clean burning alternative fuel produced from domestic, renewable resources. The fuel is a mixture of fatty acid alkyl esters made from vegetable oils, animal fats or recycled greases.
Salman Zafars insight:

Biodiesel is a clean burning alternative fuel produced from domestic, renewable resources. The fuel is a mixture of fatty acid alkyl esters made from vegetable oils, animal fats or recycled greases. Where available, biodiesel can be used in compression-ignition (diesel) engines in its pure form with little or no modifications. Biodiesel is simple to use, biodegradable, nontoxic, and essentially free of sulphur and aromatics. It is usually used as a petroleum diesel additive to reduce levels of particulates, carbon monoxide, hydrocarbons and air toxics from diesel-powered vehicles. When used as an additive, the resulting diesel fuel may be called B5, B10 or B20, representing the percentage of the biodiesel that is blended with petroleum diesel.

Biological Desulphurization of Biogas

Biological Desulphurization of Biogas | Energy Blog | Scoop.it

Biogas basically consists of methane and carbon dioxide. In addition, it also contains unwanted contaminants, especially hydrogen sulfide (H2S). Hydrogen sulfide mainly occurs because of the degradation of sulfur-containing proteins (e.g. methionine and cysteine) or the desulfurization of sulfates. The fermentation of manure and other organic wastes shows typical H2S concentrations in the range of 2,000 to 6,000 ppm) in the biogas. H2S impair the utilization of the biogas in CHP stations as it leads to formation of sulfur oxides which corrode the metal parts of the plant and drastically reduce the endurance of the engine oil in biogas motors.
