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 the various methods of producing renewable natural gas.
Biogas
Biogas is a renewable source of energy that is made from organic matter. It can be used as a fuel for vehicles, heating, and power. It can also be used to decarbonize the natural gas supply. There are many options for biogas right now, including the possibility of replacing coal in power plant boilers. But the key to biogas' future is how to make it affordable and available.
Biogas has the potential of replacing natural gas used in power plants as well as ground transportation. Biogas can eventually become biomethane. It is a renewable fuel which can be used in the production of electricity and electric vehicles.
Synthetic gas
Synthetic gas, also known as bio-SNG, e-gas, or syngas, is a natural substitute for natural gas. It is made from renewable energy sources, such as coal and biomass. It is also known under the names syngas, bio-SNG and e-gas. It can be mixed with natural gas to provide your energy needs. It can also been compressed and stored in the gas grid.
Synthetic gas can also be used to power turbines and generate electricity. It doesn't require cooling or cleaning. The hot syn-gas expands within the turbine and spins blades. The gas is then converted into electricity by the spinning blades. Gas can also heat water or dry feedstocks.
Catalytic Hydothermal Gasification
Catalytic hydrogen (CH) gasification refers to a process that uses heat to convert natural gases to fuels. This process has several advantages such as high yields, quick operation, and low capital expenditures. It is an attractive alternative to current valuation techniques and can be used close to farms.
The process involves using high temperatures to turn biomass into gas. The resulting gas is methane-rich and can be fed into the gas grid or CNG stations. The process is environmentally friendly and generates relatively little final waste. In addition, it is capable of recovering mineral salts from the biomass.
Methane from Algae
Anaerobic digestion of algae biomass can yield algae methane. This process is very efficient and doesn't require any prior treatment. Furthermore, algae can be utilized as a renewable fuel source without sacrificing their biological functions.
Algae methane can be a potential natural gas renewable source. But, it is essential to develop suitable technologies for biogas production. This is essential to minimize methane emissions. Future LCAs also must consider unrecovered nitrogen, which results in N2O.
Biomethane
Biomethane can be described as a natural gas made from biomass. It usually contains between 45 and 75 percent methane, while the remainder is carbon dioxide. Biomethane can also be used to heat or cook. The upgrading process accounts for approximately 90% of all biomethane. Upgrading refers to the use different properties to separate the various gas components. Membrane separation accounts for about 60 percent of the biomethane produced.
Biomethane, due to its flexibility and low carbon emissions, is considered a renewable gas. It is expected contribute significantly to the transition toward a carbon free energy system by 2050. It has also attracted the attention of a number of governments, including the United States, Canada, and the Netherlands.
