  title = {Technoeconomic Analysis of an Artificial Photosynthesis Fuel Plant Supplied by Raw Biogas},
  abstract = {<p>The objective of this collaboration between the Joint Center for Artificial Photosynthesis (JCAP) and Sempra Energy is to work towards development of a comparative analysis of net life-cycle energy use of a renewable fuel plant at pilot scale using water (H<sub>2</sub>O), carbon dioxide (CO<sub>2</sub>), sunlight and grid electricity as inputs. The work builds upon existing and ongoing analysis at JCAP examining hydrogen and hydrocarbon fuel production systems. We define “pilot scale” as a total fuel output of ~200 m<sup>3</sup>/hr., equivalent to ~1-2 MW continuous output (depending on the distribution of products). Note that we assume plant operation during non-sunlit hours using lowcarbon grid electricity to maximize plant capacity factor and utilization of expensive capital.</p><p>Electrochemical (EC) or photoelectrochemical (PEC) CO<sub>2</sub> reduction using a copper catalyst results in a variety of fuel products, including hydrogen (H<sub>2</sub>), carbon monoxide (CO), methane (CH<sub>4</sub>), ethylene (C<sub>2</sub>H<sub>4</sub>), other hydrocarbons and oxygenates (e.g., ethanol, propanol, acetaldehyde, formate ion/formic acid, etc.) (e.g., Hori et al., 1994, 2003), as well as oxygen (O<sub>2</sub>). All of these products have some commercial value and will result in multiple revenue streams, depending on purity.</p>},
