Today, the US Department of Energy (DOE) announced the selection of 12 small solid oxide fuel cell systems (SOFC) and hybrid electrolyzer technology development projects. According to the announcement (FOA), these projects will receive approximately $34 million in government funding.


  FOA is committed to the development of advanced technology, with the goal of advancing the small solid oxide fuel cell (SOFC) hybrid system using solid oxide electrolyzer technology to the level of commercial hydrogen production and power generation. The agency is also seeking to use syngas from gasification facilities for SOFC verification.


  The government is committed to using SOFC systems for commercial hydrogen production and power generation. Choosing to fund these projects is a big step towards this goal. "Energy Minister Dan Brouillette said. "Through cooperation with national laboratories, academic institutions and private companies, we have combined a large amount of experience and expertise to mature these technologies and finally achieve commercialization. "


   This research work also includes part of the US Department of Energy’s Office of Fossil Energy (FE) SOFC project, which focuses on the use of coal and natural gas to produce high-efficiency, low-cost, and nearly zero air emissions. The common goal of the selected projects is to ensure efficient and reliable grid power while protecting the environment.


  SOFC is an electrochemical device that directly converts the chemical energy of fuel and oxidant into electrical energy. They are unique in that they generate electricity through an electrochemical reaction rather than a combustion process. "This means that SOFC is more efficient and environmentally friendly than traditional power generation processes."


  According to the DOE FOA released in May this year, it is determined that the selected applicants have obtained the highest technical scores in their fields of interest.


   According to DE-FOA-0002300, small solid oxide fuel cell system and hybrid electrolyzer technology development project, 12 selected projects belong to three fields (AOIs).
