The twittersphere in NC on biogas has been active over the last couple weeks as an anaerobic digester project is quickly coming online. In May 2016, Optima KV obtained an agreement with Duke Energy who will use the biogas generated from anaerobic digesters at 5 contiguous swine at existing combined cycle plants. The gas from the 5 lines will be upgraded to RNG/renewable natural gas and and injected into the natural gas pipeline. Duke Energy will purchase the gas and that will help them satisfy the agricultural RPS requirement in the state.
Project development updates on twitter have been frequent, recently, showing demonstrable progress in bringing the project online:
