With the current waste problems plaguing the United States, it's possible that renewable natural gas may be the answer to the problem. The United States still heavily depends on fossil fuels as its energy source, but renewable natural gas may become an alternative. This article discusses the various methods of producing renewable natural gas.
Biogas
Biogas is a renewable resource that is produced from decomposing organic material. It is an excellent fuel for vehicles and can also serve as heating and power. It can also be used as a feedstock for bio-products and for decarbonization. Biogas is a viable option, and can be used to replace coal in power plants. But how you make biogas affordable and readily available is the key to its future.
Biogas could replace the use of natural gas for power plants, ground transport, and commercial buildings. Biogas can eventually be converted to biomethane which can be used to make electricity and electric cars.
Synthetic gas
Synthetic gas is a substitute for natural gas. It can be made from coal, biofuels, or other renewable energy sources. Synthetic gas is also known by the names bio-SNG (e-gas), or syngas. It is an alternative fuel that can be mixed with conventional natural gas to meet your energy needs. It can also compressed to be stored in a gas grid.
Synthetic gas can be used to power a turbine and produce electricity. It doesn't require cooling or cleaning. The hot syn gas expands inside the turbine. This creates spinning blades. The generator and compressor convert the hot syn-gas into electricity. The gas can also be used to heat dry feedstocks and water.
Catalytic hydothermal gazification
Catalytic hydothermal gasification (CH gasification) is a process that converts natural gas to fuels using heat and pressure. This process has several advantages such as high yields, quick operation, and low capital expenditures. It's an excellent alternative to traditional valuation methods and can even be applied near farms.
It uses high temperatures and high pressures to turn biomass into gasoline. The gas produced is methane rich and can be used to fuel the gas grid. The process is environmentally friendly and generates relatively little final waste. Additionally, the process can extract mineral salts from the biomass.
Algae methane
Anaerobic digest (AD) can produce algae methane from biomass. This process is extremely efficient and does not require any pretreatment. Algae can be used as a source of renewable fuel without compromising their biological function.
Algae-methane is a potential source of natural gas. But, it is essential to develop suitable technologies for biogas production. This is necessary to reduce methane losses during the process. In addition, future LCAs must take into account the unrecovered nitrogen that results in N2O.
Biomethane
Biomethane is a natural gas that is generated from biomass. It typically contains 45 to 75 percent methane and the rest is CO2. Biomethane is useful for heating, cooking, and electricity. The process of upgrading accounts for 90% of the biomethane produced. Upgrading refers to the use different properties to separate the various gas components. About 60 percent of biomethane is produced via membrane separation.
Biomethane has low carbon emissions and flexibility. It is therefore considered a natural gas that can be used to generate renewable energy. It is expected to play an important role in the transition towards a zero-carbon energy system by 2050. It has been noticed by a variety of countries, including the United States, Canada and the Netherlands.
