Biogas and membranes are key tools for decarbonization

0

Companies around the globe are fighting climate change with their pledges to become carbon neutral. Amazon, Shell, Walmart and many others have pledged and invested significant capital into reducing their carbon emissions to Net Zero within the next couple of decades. 

Renewable natural gas (RNG), also called biomethane, is a crucial part of the global decarbonization effort. Along with energy from solar and wind, RNG is non-fossil and can be used as a method for lowering the overall carbon emissions in, for example, natural gas-fueled vehicles, heating or power generation.

In the new US Inflation Reduction Act (IRA) elements that relate to clean energy, RNG is now eligible for tax credits – something that has existed for many years for wind and solar. RNG, however, has a unique advantage over those well-known technologies. This is that it represents a carbon-negative lifecycle emissions score to help fully lower any power generation emission standard to zero, making RNG very desirable to companies worldwide. This is a significant difference from even wind or solar, which still represent a positive emissions score according to the US Environmental Protection Agency (illustrated in figure 1).
