New Fuel Cell Efficiently Both Sequesters Carbon Dioxide and Produces Energy



(p. B1) For years, FuelCell Energy has been considered a company to watch. Its technology promised to help economically reduce carbon dioxide emissions from power plants, which could help combat climate change. The Danbury, Conn., company might be able to make a difference, experts said, if only it had a partner with really deep pockets.

Now it has one.

In an agreement announced on Thursday [May 5, 2016], Exxon Mobil said it had tightened an existing relationship with FuelCell in hopes of taking the technology from the lab to the market.


. . .


The company's fuel cells are already used to provide clean energy in about 50 locations around the world but without a connection to fossil-fuel power plants, as envisioned in the new agreement.

The fuel cells use a high-temperature molten carbonate salt mixture. Carbon dioxide flows into the fuel cell and emerges in a concentrated form that is ready for storage.

It is this idea of matching up power plants, which produce carbon dioxide, with fuel cells that are hungry for it that led to a collaboration between Exxon Mobil and FuelCell that started more than four years ago.

The result, at least so far in the laboratory, is that the fuel cells effectively isolate and compress the carbon dioxide while producing enough power to more than make up for the energy cost of capturing the carbon.
