Renewable Gas

Renewable Gas

Renewable Gas is a type of natural gas (RNG) produced from organic materials such as agricultural waste, food waste, and wastewater. It is produced through a process called anaerobic digestion, which involves breaking down organic matter in the absence of oxygen to produce biogas, which is then purified and upgraded to Renewable Gas.

Renewable Gascan be used as a substitute for natural gas in the energy system, which can help to reduce carbon emissions by replacing fossil fuels with a renewable source of energy. In addition, producing Renewable Gasfrom organic waste can help to reduce methane emissions from the decomposition of organic waste in landfills, which is a potent greenhouse gas.

Renewable Gas can also be used as a fuel for transportation, either as compressed natural gas (CNG) or liquefied natural gas (LNG) in vehicles. Using Renewable Gas as a transportation fuel can help to reduce emissions from the transportation sector, which is a significant contributor to greenhouse gas emissions.

By producing and using Renewable Gas, countries can reduce their greenhouse gas emissions and contribute to achieving NetZero or carbon neutrality.

Renewable Gas

There are several large global Renewable Gas projects that are being developed or have already been implemented:

Denmark's biogas plant
Denmark's biogas plants: Denmark has one of the most advanced biomethane industries in the world, with more than 200 biogas plants producing biomethane from agricultural waste, food waste, and other organic materials. The biomethane is injected into the natural gas grid and used to fuel vehicles, heat buildings, and generate electricity.
California's dairy digesters
California's dairy digesters: California is home to one of the largest biomethane projects in the world, with more than 300 dairy digesters producing biomethane from cow manure. The biomethane is upgraded and injected into the natural gas grid, providing renewable natural gas to homes and businesses.
UK's biomethane injection projects
UK's biomethane injection projects: The UK has several biomethane injection projects, where biomethane is produced from organic waste and injected into the natural gas grid. These projects provide renewable natural gas to homes and businesses, reducing emissions from fossil fuels.
Brazil's sugarcane biogas projects
Brazil's sugarcane biogas projects: Brazil has several biogas projects that produce biomethane from sugarcane waste. The biomethane is used to fuel vehicles and generate electricity, helping to reduce emissions from the transportation and electricity sectors.
Sweden's waste-to-energy plants
Sweden's waste-to-energy plants: Sweden has several waste-to-energy plants that produce biomethane from municipal solid waste. The biomethane is used to fuel vehicles and heat homes and buildings, helping to reduce emissions from the transportation and heating sectors.
Richgro’s Anaerobic Digestion Plant at Jandakot
Richgro’s $8 million enclosed Anaerobic Digestion Plant at Jandakot near Perth in Western Australia is turning tonnes of waste that would otherwise go to landfill into clean energy and power that can be exported back to the grid.

By traditional fuels with Renewable Gas, emissions of greenhouse gases such as carbon dioxide and methane can be significantly reduced. The process of producing Renewable Gas from organic waste can help to reduce methane emissions from the decomposition of waste in landfills.

  • Supporting circular economy: Renewable Gas is often produced from organic waste materials such as agricultural waste, food waste, and wastewater. By using these waste materials to produce energy, a circular economy can be created, where waste is transformed into a valuable resource.
  • Improving air quality: When used as a transportation fuel, Renewable Gas can significantly reduce emissions of harmful pollutants such as nitrogen oxides (NOx), particulate matter (PM), and sulfur dioxide (SO2), which can have negative impacts on human health and the environment.
  • Creating local jobs: The production of Renewable Gas can create local jobs in the agriculture, waste management, and energy sectors, supporting local economies.
     

Overall, Renewable Gas can provide a renewable source of energy, reduce greenhouse gas emissions, support a circular economy, and improve air quality.
