    • Algal amendment enhances biogenic methane production from coals of different thermal maturity 

      Platt, George A.; Davis, Katherine J.; Schweitzer, Hannah; Smith, Heidi J.; Fields, Matthew W.; Barnhart, Elliott P.; Gerlach, Robin (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-10)
      The addition of small amounts of algal biomass to stimulate methane production in coal seams is a promising low carbon renewable coalbed methane enhancement technique. However, little is known about how the addition of algal biomass amendment affects methane production from coals of different thermal maturity. Here, we show that biogenic methane can be produced from five coals ranging in rank ...

    • Effect of an algal amendment on the microbial conversion of coal to methane at different sulfate concentrations from the Powder River Basin, USA 

      Schweitzer, Hannah; Smith, Heidi J.; Barnhart, Elliott P.; Gerlach, Robin; Fields, Matthew W. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-29)
      Biogenic methane is estimated to account for one-fifth of the natural gas worldwide and there is great interest in controlling methane from different sources. Biogenic coalbed methane (CBM) production relies on syntrophic associations between fermentative bacteria and methanogenic archaea to anaerobically degrade recalcitrant coal and produce methanogenic substrates. However, very little is known ...
