I like the past tense in the last paragraph:

FuelCell Energy invites the interested parties to work collectively toward deployment of an intriguing technology for carbon capture from the flue gas of power plants and industrial complexes. The technology is carbonate fuel cells, which has been demonstrated globally in MW-scale power plants. The carbonate fuel cell is versatile, with the capability to perform carbon capture from the flue gas of other plants while generating ultra-clean electric power using a supplemental fuel such as biogas or natural gas. Systems can also be configured using carbonate fuel cells to produce by-product hydrogen gas for export or other uses by the host facility, such as for process needs at refineries. The flexibility of hydrogen production stems from the internal reforming capabilities of the carbonate fuel cell technology, without the need for complex external reforming unit operations. It also has been shown that the carbonate fuel cell destroys ~70% of NOX in the flue gas, reducing or eliminating capital and operating costs for NOX destruction equipment. Overall, the additional benefits of simultaneous power generation, hydrogen recovery, and NOx destruction provides the added values that will benefit the reduction of the cost of CO2 capture down to acceptable levels.

One of the great features of the technology is the modularity of the carbonate fuel cell hardware, providing an affordable approach to carbon capture, with systems that can be configured to capture >90% of the CO2 in the exhaust of a plant, or smaller systems that can be added in as little as 10% capture increments with no appreciable change in the cost of power and with minimum capital outlay. The technology is versatile to be applied to flue gas resulting from the combustion of a variety of fuel sources including coal, natural gas, and even biomass. As an example, a recent study was focused on carbonate fuel cell application to the flue gas of a biomass fed power plant in Great Britain.
