The technology for coal liquefaction to synthetic fuels is not new. In 1913 Dr. Friedrich Bergius discovered the technique of adding hydrogen to coal at a pressure of 20.3 MPa (2940 psia) and a temperature of about 723 K (842°F). Under these conditions most oxygen was hydro-...

Project delineates between cleaner new gas technologies and polluting old natural gas technologies—and reserves a third cleanest category for energy efficiency/conservation, solar, wind, and geothermal (but not hydro or biomass). 

Renewable electricity technologies can supply energy to remote or off grid communities. They can also feed electricity into the grid. Technologies include photovoltaic, wind and low head hydro.

Hydrogen, however, can be produced using sustainable technologies that are nowadays still not applied at large scale the most promising ones are water splitting by electrolysis using sustainably produced electricity (e.g., wind, hydro, and sun) and processes based on sustainable production and utilization of biomass.3... 

MTO [Methanol to olefins] A catalytic process for converting methanol to olefins, mainly propylenes and butenes. Developed by Mobil Research Development Corporation and first demonstrated in 1985. Another version of this process was developed by UOP and Norsk Hydro and has been ran at a demonstration unit at Porsgrunn, Norway, since June 1995. It is based on fluidized bed technology using a SAPO molecular sieve catalyst. It converts 80 percent of the carbon in the feed to ethylene and propylene. 

Gas-to-liquids (GTL) is the chemical conversion of natural gas into petroleum products. Gas-to-liquid plants use Fischer-Tropsch technology, which first converts natural gas into a synthesis gas, which is then fed into the Fischer-Tropsch reactor in the presence of a catalyst, producing a paraffin wax that is hydro-cracked to products (see also Chapter 7). Distillate is the primary product, ranging from 50% to 70% of the total yield. 

A 250 kilowatt atmospheric system is planned for a Toronto, Ontario, Canada site. The system will be operated by Ontario Power Technologies (formerly Ontario Hydro). The unit will supply 145 kilowatts of heat to the site heating system. Electric efficiency is expected to be about 47% (LHV). Operation of the combined heat and power system is expected in late 2001.
