What’s biogas?
Biogas is a renewable fuel produced by the breakdown of organic matter comparable to food scraps and animal waste. It can be utilized in quite a lot of ways together with as vehicle fuel and for heating and electricity generation. Read on to be taught more.
What is biogas? How is biogas produced?
Biogas is an environmentally-pleasant, renewable energy source.
It’s produced when natural matter, equivalent to food 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 surroundings the place there isn’t a oxygen.
It could possibly occur naturally or as part of an industrial process to deliberately create biogas as a fuel.
What kind of waste can be used to produce biogas?
A wide number of waste material breaks down into biogas, including animal manure, municipal garbage/ waste, plant material, meals waste or sewage.
Which gases does biogas contain?
Biogas consists mainly of methane and carbon dioxide. It might probably additionally include small quantities of hydrogen sulphide, siloxanes and some moisture. The relative quantities of these differ depending on the type of waste concerned in the production of the ensuing biogas.
What can biogas be used for?
To fuel vehicles – if biogas is compressed it can be utilized 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 a similar way to methane; this can embrace for cooking and heating.
Biogas: 6 fascinating information
1. Biogas is a gas of many names
Biogas is most commonly additionally known as biomethane. It’s also sometimes called marsh gas, sewer gas, compost gas and swamp gas within the US.
Biogas is a naturally occurring and renewable source of energy, ensuing from the breakdown of organic matter. Biogas is to not be confused with ‘natural’ gas, which is a non-renewable supply of power.
2. Biogas and biomass: relatedities and differences
Biomass and biogas are both biofuels; they are often burnt to produce energy. However biomass is the solid, natural material. Biomass has been used as an energy supply since humans first discovered fire and burnt wood, plants and animal dung to create energy.
In the present day, many power stations run by burning a biomass of compressed wood pellets – a by-product of timber and furniture-making. By replacing 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 happening in nature for millions of years, even earlier than fossil fuels, and continues to occur throughout us within the natural world. In the present day’s industrial conversion of natural waste into energy in biogas plants is just fast-forwarding nature’s ability to recycle its helpful resources.
The first human use of biogas is thought to date back to 3,000BC in the Middle East, when the Assyrians used biogas to heat their baths.
A seventeenth century chemist, Jan Baptist van Helmont, discovered that flammable gases may come from decaying organic matter. Van Helmont is also answerable for bringing the word ‘gas’, from the Greek word chaos, into the science vocabulary.
The primary massive anaerobic digestion plant dates back to 1859 in a leper colony in Bombay.
An ingenious Victorian engineer, John Webb from Birmingham, created the Sewage Lamp, which converted sewage into biogas to light road 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, earlier than chemical treatments. Within the developing world the anaerobic process is still recognised as an affordable, natural various to chemical substances and the reduction of dysentery bacteria.
And let’s not forget that in Mad Max Beyond 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 power the desert-chasing vehicles.
4. Immediately China leads the world in the usage of biogas
China has the most important number of biogas plants, with an estimated 50 million households utilizing biogas. These are principally in rural areas and small-scale house and village plants.
