Uses & Benefits of RNG
Benefits of RNG
Using RNG, thereby reducing methane emissions, produces positive outcomes for local communities and the environment. RNG production projects create partnerships among citizens, nonprofit organizations, local governments, and industry in sustainable community planning. The benefits of RNG projects are significant for the following reasons.
Reduce Greenhouse Gas Emissions
With a global warming potential more than 25 times greater than CO2 and a short (12-year) atmospheric life, methane is a potent greenhouse gas that is a key contributor to global climate change. As a result, reducing methane emissions from MSW landfills is one of the best ways to achieve a near-term beneficial impact in mitigating global climate change. In addition, methane contributes to background tropospheric ozone levels as an ozone precursor. Finally, many of the technologies and practices that reduce methane emissions also reduce associated emissions of volatile organic compounds (VOCs), odors, and other local air pollutants.
*CO2 emissions from MSW landfills are not considered to contribute to global climate change because the carbon was contained in recently living biomass. The same CO2 would be emitted as a result of the natural decomposition of the organic waste materials outside the landfill environment.
Produce Renewable Hydrogen
Hydrogen generators can use RNG or biomethane to create renewable hydrogen (RH2), providing similar opportunities for farmers and local communities to create clean, storable energy, while reducing waste, decarbonizing and making use of existing infrastructure.
Although still a relatively new commodity, RH2 at scale could significantly reduce carbon emissions from thermal and mobility applications. When RH2 production is paired with carbon capture and sequestration, the process is ultimately carbon-negative. Therefore, the material used to produce RNG today can be shifted toward RH2 production in the long run, providing another avenue for zero-carbon and carbon-negative renewable gas in thermal and mobility applications.
