When it comes to RNG, the quality of the fuel can be measured on a variety of factors, even down to looking at if a truck is used to transport the gas. In the renewable natural gas industry, this measurement is known as the carbon intensity of the gas.
Think of making renewable natural gas like making a cake: different ingredients and flavours will create different products!
That’s one thing that still amazes me about baking, using the same ingredients in different ways will result in different outcomes.
