Abstract: A carbon dioxide removal system includes: an absorption system including a first absorption stage and a second absorption stage. The first absorption stage includes: a first compressor configured to receive and compress a first carbon dioxide-containing exhaust stream from an anode of a fuel cell, and a first direct contact absorption cooling tower configured to absorb carbon dioxide from the compressed first exhaust stream and lower a temperature of the compressed first exhaust stream using a first solvent stream containing a physical solvent, to generate a second exhaust stream. The second absorption stage includes: a second compressor configured to receive and compress the second exhaust stream from the first absorption stage, and a second direct contact absorption cooling tower configured to absorb carbon dioxide from the compressed second exhaust stream and lower a temperature of the compressed second exhaust stream using a second solvent stream containing a physical solvent.

Abstract: An energy storage system includes a power plant configured to generate an exhaust gas comprising carbon dioxide. The energy storage system further includes a first fuel cell configured to operate in reverse as an electrolyzer. The first fuel cell is configured to receive at least a portion of the exhaust gas from the power plant. An anode is configured to receive carbon dioxide via the exhaust gas and methane from a separate feed, and the anode is configured to output a hydrogen-containing gas mixture. The energy storage system further includes a reformer configured to methanate the hydrogen-containing gas mixture to convert substantially all of the carbon monoxide in the hydrogen-containing gas mixture to methane. The energy storage system further includes a second fuel cell operating in reverse as a hydrogen pump, the second fuel cell configured to separate hydrogen from a gas mixture output by the reformer.

Abstract: A system for draining an airfan heat exchanger includes an airfan heat exchanger including a housing, a pressurized gas source fluidly coupled to the airfan heat exchanger and configured to hold a purging gas at a predetermined pressure, and a controller configured to control delivery of the purging gas to the airfan heat exchanger. The pressurized gas source is configured to provide a flow of the purging gas to the airfan heat exchanger and thereby drain water held in the airfan heat exchanger. The purging gas to the airfan will cause the airfan to drain quickly avoiding potential damage to the airfan from freezing of the water during cold weather.
