Renewable natural gas could be the solution to America's current waste problems. While the United States heavily relies on fossil fuels for energy, renewable natural gas could become a viable alternative in the next few years. This article discusses several methods of producing natural gas from renewable sources.
Biogas
Biogas, a renewable energy source, is made from organic matter that has been decomposed. It is an important fuel for vehicles as well as being used for heating and electricity. It is also a good feedstock for bioproducts and can be used in decarbonization of natural gas supplies. There are many uses for biogas at the moment, including replacing coal in power plants. But the key to biogas' future is how to make it affordable and available.
Biogas has the potential to replace mined natural gas in power plants, ground transportation, and commercial buildings. Biogas can be eventually converted into biomethane. This renewable fuel can then be used to create electricity and electric automobiles.
Synthetic gas
Synthetic gas can be described as a natural gas substitute made from coal, biomass and other renewable energy sources. It is also called bioSNG, syngas, and egas. It can be mixed with natural gas to provide your energy needs. It can be compressed to be stored within the gas grid.
Synthetic gas can be used to power a turbine and produce electricity. It doesn’t need to cool or be cleaned. The hot, syn-gas expands inside a turbine and spins blades. The hot syn-gas expands inside the turbine, creating spinning blades that power a compressor as well as a generator. This converts the gas into electricity. You can heat the gas to make water and dry feedstocks.
Catalytic hydrothermal gasification
Catalytic hydrothermal (CH) gasification uses heat and pressure to transform natural gas into fuels. The process has several advantages, including high yields, rapid operation, and low capital costs. It is an attractive alternative to current valuation techniques and can be used close to farms.
It uses high temperatures and high pressures to turn biomass into gasoline. The resulting gas is methane-rich and can be fed into the gas grid or CNG stations. The process is safe for the environment and produces minimal waste. In addition, it is capable of recovering mineral salts from the biomass.
Algae methane
Anaerobic digestion (AD), of algae can produce algae methane. This process is extremely efficient and does not require any pretreatment. Algae can also be used as a renewable fuel source, without losing their biological functions.
Algae methane can be a potential natural gas renewable source. However, appropriate technologies must be developed for biogas production. This is crucial to minimize the methane loss during the process. Future LCAs will also need to account for the N2O-rich unrecovered nitrogen.
Biomethane
Biomethane (also known as biogas) is a natural, renewable gas. It is made from biomass. It generally contains 45 to 75 per cent methane and the remainder is CO2. It can be used to generate electricity, heat and for cooking. About 90% of biomethane can be produced by upgrading. The use of different properties to separate gas components is what upgrades involve. About 60 percent of biomethane is produced via membrane separation.
Biomethane is a renewable natural gas due to its flexibility as well as low carbon emissions. It is expected to play an important role in the transition towards a zero-carbon energy system by 2050. It has also been spotted by several countries, including the United States of America, Canada, and the Netherlands.
