RE:Anyone know ?The cost of setting up biogas plants together with the necessary infrastructure to distribute the gas has to be calculated and considered in terms of what the expected return from the sale of the RNG would be out in the future..ie. a cost/ benefit calculation.. the uncertainty around future natural gas prices given the associated volatility makes the calculation difficult.. what may alleviate this uncertainty is a climate bill that'll give some sort of price guarantee through a tax break for both the producer and consumer in order to encourage RNG production and consumption... government subsidies benefiting RNG production is another possibility... another favourable factor for RNG going forward is the requirement that conventional oil and gas producers, have to produce increasing percentages of their products from renewable sources.. these requirements are gaining traction worldwide as governments are now realising the destruction and associated costs caused by both CO2 and methane gas being released into the atmosphere... these costs are now being processed in terms of the cost/benefit analysis in the shift to renewable energy..
