United Technologies Corporation internals

Development History Phosphoric acid fuel cells were developed from the 1970s through the 1990s by several companies in the United States, including ONSI, a division of International Fuel Cells (IFC), which eventually became United Technologies Corporation... 

Around 1993, United Technologies, through its International Fuel Cells Corporation and ONSI subsidiaries, began building 200-kW phosphoric acid fuel cell plants. About 200 of these plants have been deployed, around the world, at a rate of about two dozen a year since the program started. So far, these are the only commercially available fuel cell plants. 

Corporate-Level Metrics. Indicators and metrics of sustainability have also been identified and developed at the community, corporate, business unit, or even process or technology levels. Information regarding sustainability indicators at the community level may be found, for instance, at the International Sustainability Indicators Network s website (www.sustainabilityindicators.org).

In the United States, most of the consumption of silane is internal. Silane is consumed in a free-space polycrystalline silicon production facility (3000 t/yr) at Moses Lake, Washington. This facility was built by Union Carbide but as of 1996 was operated by Advanced Silicon Materials Inc., a joint venture controlled by Komatsu. Silane is also consumed in a fluidized-bed polycrystalline silicon production facility (1250 t/yr) in Pasadena, Texas, built by Ethyl Corporation and operated as of 1996 by MEMC, a publicly traded company 51% owned by Htls. The world merchant market for silane is about 250 t/yr. The bulk price for silane is 80— 120/kg much higher pricing is placed on small packages. The primary use of silane is in microelectronics. Minor applications exist in reprography, ie, in photocopiers, and in specialty glass technology.
