RNG and CO2 priceThe Brightmark project at 4 dairy farms in Florida is reported to produce 171,000 MMBTU/yr of RNG. The dairies have a total of 9,900 cows and the project processes 230,000 MT/yr of manure. On a pro-rata basis, the 80,000 MMBTU/yr project in California would have a cluster of dairies with a total of 4,600 cows and process 108,000 MT of manure.
Capturing the rogue emissions is the very important aspect of RNG projects because the cow manure emits methane that is about 80 times more potent as a GHG than CO2 (over 20 years. It) and it also releases NO2 which is about 300 times more potent. These projects prevent a lot of CO2 equivalent GHG from entering the atmosphere so the RNG producers (and their suppliers like GRN and XBC) should become very profitable if and when the price of CO2 rises to level that accurately reflects the urgency of the climate crisis. Unfortunately, that is not yet the case. Today about 40% of Canadians (probably more in the US) still believe CO2 is not a problem. (Apart from the Ukraine war, that likely helps to explain why CVE is up about 50% YTD and GRN is down about 40%.)
Globally, the average cost for emitting CO2 is about $CAD 4/MT. In Europe the average cost is about $CAD 126/MT. In Sweden it is about $170/MT. In Canada it is about $50. In the US it is ZERO.
