Additionally, when hydrogen is combined with carbon dioxide through a catalyst, we can produce methane. So, we can use wind energy to make renewable methane or to make renewable natural gas,” he added.
What can methane gas be converted into?
Alternatively, methane can be converted into a useful mixture of hydrogen and carbon monoxide, called "synthesis gas," by reaction with carbon dioxide in what is referred to as dry reforming of methane (DRM).

You can make biogas energy with a DIY methane generator. Producing methane from manure using your own small scale waste to energy biogas digester is feasible for many small farms. What is Biogas Energy? Biogas energy is fueled by burning methane produced by the decomposition of organic wastes.
How much electricity does methane produce?
Electrical potential estimation was calculated with the assumption of 1 m3 biogas has a calorific value of 22 MJ, and 1 m3 methane is equal with 36 MJ. With assumption of electrical conversion efficiency of 35%, therefore 1 m3 biogas will yield 2.14 kWh (electricity) and 1 m3 methane will yield 10 kWh.

How is methane in garbage dump used as fuel and converted into electrical energy?
The methane gas contained in landfill gas can be used as a turbine player through the combustion process. The use of landfill gas generated from the Waste Disposal Site (TPA) as an electric energy generator is called a Waste Power Plant (PLTSa).
How can waste be turned into electricity?
We can generate electricity by burning solid waste found in the landfills. A community must have a waste to energy facility that incinerates garbage and transforms chemical energy into thermal energy. The most common technology for waste to energy conversion is incineration.
How can a landfill be used to generate electricity there are two ways?
Landfill gas is collected from landfills by drilling "wells" into the landfills, and collecting the gases through pipes. Once the landfill gas is processed, it can be combined with natural gas to fuel conventional combustion turbines or used to fuel small combustion or combined cycle turbines.
How is electrical current generated?
Electrical current may be generated through biological means from organic substrates in microbial fuel cells (MFCs) in which microbes transfer electrons extracellularly (exoelectrogens) 1 , 2. In MFCs, exoelectrogens deposit electrons on an anode, from which the electrons migrate to the cathode to create an electrical current; at the cathode, the electrons are passed to another electron acceptor. In a typical dual-chamber set-up, a proton-conducting membrane is used between the anode and cathode chambers to complete the circuit by allowing excess positive charge in the anode (in the form of protons) to migrate to the cathode 3 ( Supplementary Fig. 1 ). Use of MFCs has led to the successful generation of electrical current from a wide variety of substrates, from both natural and artificial sources (including acetate 4, glucose 5, and natural 6 and artificial 7 wastewaters) 8. However, with methane as a substrate, only negligible electrical power has been reported using uncultured anaerobic methane-oxidizing consortia isolated from oceanic sediment 9, 10.
Why is sulfurreducens added to MFCs?
sulfurreducens, methane-acclimated sludge was added to the MFCs to provide other potential consortial members to produce electricity from methane and other by-products of methane catabolism.

How can methane be used to generate electricity?
Using Turbines, the high pressure methane gas can be utilized for generating Electricity through generators. The methane can be obtained as a by product of solids waste in a Sewage treatment plant.So the power needed to run the plant can be produced within the plant. This is one way to do it besides many others.
How to use natural gas for electricity?
Use it as fuel in a gas turbine-generator set. The most basic natural gas-fired electric generation consists of a steam generation unit, where fossil fuels are burned in a boiler to heat water and produce steam that then turns a turbine to generate electricity. Use methane gas as fuel for internal combustion engines or use it as fuel for boiler ...

The cow waste produces 250 to 300 kilowatts of electricity daily, enough to power 300 to 350 homes, according to the utility. “We’re making a resource out of a waste stream,” said Bill Rowell, who is running for the State Senate.
How much does the Rowell family make from electricity?
Rowell said they earned about $200,000 from electricity annually, and with the additional cows should receive $235,000 to $240,000 in revenue from electricity. The Rowells are also transforming commercial waste.
Is Buckeye Power going to turn waste into electricity?
In Ohio, Buckeye Power went online with a digester at the end of August and plans to turn waste from a chicken farm into electricity next year. “We were interested in finding a type of green power that was, No. 1, not intermittent, like wind or solar,” said Steve Oden, a spokesman for Buckeye, which will not charge extra for the power.
How does methane get into landfill?
To produce methane, waste that is deposited into a landfill first undertakes an aerobic (or ‘with oxygen’) decay stage which results in very low methane levels. Generally after less than a year, anaerobic (or ‘without oxygen’) circumstances are created and methane-producing bacteria begin their decomposition of the waste, which produces methane.
What is the process of converting landfill gas to electricity?
Combustion Engine. When it comes to converting landfill gas to electricity, the combustion engine is one of the major components to the process. Otherwise known as a biogas generator, a combustion ene does all the hard work when it comes to converting landfill gas to electricity.
What is landfill gas used for?
burning, electricity etc) Once treated, the gas can then be used as fuel for a combustion engine, in order to create electricity for various purposes.
What is the main gas released from landfills?
A variety of gases are released in landfills, however the major one (over 50% of the total amount) is methane, a contaminating greenhouse gas. Methane is around 21 times more powerful than carbon dioxide and the major concern when it comes to landfill gas, with man made waste being the third largest source of methane.
Where is landfill gas deposited?
The landfill waste begins to decay and emit landfill gas, namely methane. The landfill gas rises to the top of the landfill and is collected in pipes located in/around the landfill.
Is landfill gas bad for electricity?
Although there are very few disadvantages to consider, the big one is the quality of landfill gas. A lot of landfill gas can be very low quality, which makes it very difficult (and sometimes impossible, as well as being potentially damaging) for biogas generators to run and generate electricity. When this occurs, the gas needs to be flared anyway - so it sounds like you are merely ‘doubling up’ on technology. In saying this, there are companies which have placed generators on the market which can deal with methane gas levels as low as 45% (see the Inoplex Landfill Gas Generator as an example).
