What is biogas?
Biogas is a renewable fuel produced by the breakdown of natural matter such as food scraps and animal waste. It can be used in a variety of ways together with as vehicle fuel and for heating and electricity generation. Read on to study more.
What is biogas? How is biogas produced?
Biogas is an environmentally-pleasant, renewable energy source.
It’s produced when natural matter, equivalent to meals or animal waste, is broken down by microorganisms in the absence of oxygen, in a process called anaerobic digestion. For this to take place, the waste material needs to be enclosed in an environment where there isn't any oxygen.
It could actually happen naturally or as part of an industrial process to intentionally create biogas as a fuel.
What kind of waste can be used to produce biogas?
A wide variety of waste materials breaks down into biogas, together with animal manure, municipal garbage/ waste, plant material, meals waste or sewage.
Which gases does biogas comprise?
Biogas consists mainly of methane and carbon dioxide. It can also include small quantities of hydrogen sulphide, siloxanes and some moisture. The relative quantities of these range relying on the type of waste concerned within the production of the ensuing biogas.
What can biogas be used for?
To fuel vehicles – if biogas is compressed it can be used as a vehicle fuel.
As a replacement for natural gas – if biogas is cleaned up and upgraded to natural gas standards, it’s then known as biomethane and can be used in an identical way to methane; this can embrace for cooking and heating.
Biogas: 6 fascinating details
1. Biogas is a gas of many names
Biogas is most commonly also known as biomethane. It’s additionally generally called marsh gas, sewer gas, compost gas and swamp gas within the US.
Biogas is a naturally occurring and renewable supply of energy, ensuing from the breakdown of natural matter. Biogas is not to be confused with ‘natural’ gas, which is a non-renewable source of power.
2. Biogas and biomass: relatedities and variations
Biomass and biogas are both biofuels; they are often burnt to produce energy. However biomass is the strong, natural material. Biomass has been used as an energy source since people first discovered fire and burnt wood, plants and animal dung to create energy.
At the moment, many energy stations run by burning a biomass of compressed wood pellets – a by-product of timber and furniture-making. By changing fossil-fuel coal, biomass enables renewable electricity to be produced.
3. Biogas is not a new discovery
The anaerobic process of decomposition (or fermentation) of organic matter has been taking place in nature for millions of years, even earlier than fossil fuels, and continues to happen all around us in the natural world. In the present day’s industrial conversion of organic waste into energy in biogas plants is simply fast-forwarding nature’s ability to recycle its helpful resources.
The first human use of biogas is assumed to this point back to 3,000BC in the Middle East, when the Assyrians used biogas to heat their baths.
A 17th century chemist, Jan Baptist van Helmont, discovered that flammable gases could come from decaying organic matter. Van Helmont is also chargeable for bringing the word ‘gas’, from the Greek word chaos, into the science vocabulary.
The first giant anaerobic digestion plant dates back to 1859 in a leper colony in Bombay.
An inventive Victorian engineer, John Webb from Birmingham, created the Sewage Lamp, which transformed sewage into biogas to light avenue lamps. The only remaining Webb Sewer Lamp in London is now just off The Strand in Carting Lane – or as some wags would have it, Farting Lane.
Anaerobic digestion was used as a means to treat municipal wastewater, before chemical treatments. In the growing world the anaerobic process is still recognised as an inexpensive, natural alternative to chemical compounds and the reduction of dysentery bacteria.
And let’s not overlook that in Mad Max Past Thunderdome the submit-apocalyptic settlement Bartertown, run by Tina Turner’s terrifying Aunty Entity, is powered by a pig-farm biogas system with biogas used to energy the desert-chasing vehicles.
4. Today China leads the world in the use of biogas
China has the largest number of biogas plants, with an estimated 50 million households using biogas. These are largely in rural areas and small-scale residence and village plants.
