Open the CIPO recordAbstract From the Canadian patent
Hydrogen (2) is used as the fuel source in a power plant. The hydrogen (2) is combusted (8) in pure oxygen (1) to produce steam (71) which is then expanded , in one or more power turbines (24 26, 28), with the steam being reheated by further combustion of hydrogen with oxygen between each successive turbine (10, 12). Heat available in the steam discharged from turbines (76) is recuperated (6) by transferring it to the hydrogen and oxygen prior to combustion. Since no hydrocarbon fuel or atmospheric air is used for combustion, Nox generation is eliminated so that the only emission (77) from the power plant is water.

Why it's free to use
- Filed February 25, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 25, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 25, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
