A new 1.4 MW utility-owned a fuel cell is now in full operation at Cal State San Bernardino.
Duane Tilden‘s insight:
>”Electricity generated by the fuel cell is going straight into the Edison grid, and the university will be able to utilize the waste heat it produces to preheat the campus heating system, resulting in an estimated annual savings of $120,000 from avoided natural gas costs,” said Tony Simpson, senior director of facilities services at Cal State San Bernardino.
The combined heat and power configuration —known as cogeneration — of the fuel cell will reduce the campus’s carbon dioxide emissions by lessening reliance on the high temperature hot water generators currently in operation. The fuel cell will continue to use natural gas to generate ultra-clean electricity through an electrochemical reaction, but because there is no combustion, unhealthful emissions are reduced.
Additionally, the fuel cell is highly efficient, generating more power from a given unit of fuel and lower greenhouse gas emissions compared to combustion-based power sources in a similar size range. Cogeneration DFC power plants can achieve total thermal efficiencies up to 90 percent, depending on the application.<

Duane Tilden‘s insight:
>The plant will be built in western Poland in the city of Gorzów Wielkopolski. Within the scope of turnkey construction, Siemens will deliver two SGT-800 gas turbines, one SST-400 steam turbine, three 11 kilovolt (kV) generators and two heat recovery steam generators. In addition, Siemens was awarded a long-term 12 years maintenance agreement for the gas turbines. The Gorzów plant will be fired with nitrogen-rich natural gas from gas reserves located in western Poland. This type of gas has a lower calorific value than conventional natural gas. […]
The Gorzów power plant will replace a currently used coal-fired block at the same location. The combined cycle power plant with district heat extraction will be able to generate electricity in a much more efficient and environmentally friendly manner. Compared to the old coal-fired power plant, the new plant will produce 95 percent less sulfur dioxide emissions, more than 30 percent less nitrogen dioxide emissions and more than 95 percent less particulate emissions.<
