The new Clean Air Act will result in a permanent 10 million ton reduction in sulfur dioxide (SOj) emissions from 1980 levels. To achieve this, EPA will allocate allowances of one ton of sulfur dioxide in two phases, The first phase, effective January 1, 1995, requires 110 powerplants to reduce their emissions to a level equivalent to the product of an emissions rate = (2,5 lbs of S02/mm Btu) x (the average mm Btu of their 1985-1987 fuel use). Plants that use certain control technologies to meet their Phase 1 reduction requirements may receive a two year extension of compliance until 1997. The new law also allows for a special allocation of 200,000 annual allowances per year each of the 5 years of Phase 1 to powerplants in Illinois, Indiana and Ohio.

The DMFC is the most attractive type of fuel cell as a powerplant for electric vehicles and as a portable power source, because methanol is a liquid fuel with values for the specific energy and energy density being about equal to half those for liquid hydrocarbon fuels (gasoline and diesel fuel).

Europe The Energetic Utility of Milan, the National Agency for Energy, New Technology and Environment (ENEA), and Ansaido Ricerche designed, built, and tested 1.3 MWe PAFC system in Milan. The powerplant had an actual capacity of 930 kW and an energy efficiency of 38% (LHV). It has operated for over 5,000 hours. 

Mitsubishi Electric has developed a 200 kWe class on-site powerplant. To date, 11 units are being operated in the field with applications ranging from an electric utility to a brewery factory. Four of the units have operated more than 2,000 hours.

The intent of Congress to more stringently restrict oil imports appears in the Powerplant and Industrial Fuel Use Act (FUA) (3), now part of the National Energy Act (NEA). The new legislation removes the burden of proof from the government in justifying conversion from oil and gas to coal. Instead, it is now incumbent upon the stationary source to demonstrate why it cannot make the conversion.

The near-term prospects for fuel cell vehicles were also overhyped in the late 1990s. In November 2002, a major study titled Hybrid Competitive Automobile Powerplants concluded, The industry is currently experiencing a backlash to the just around the corner hype that has surrounded the automotive fuel cell in recent years. 6... 

U ecently, interest in sulfur utilization in asphalt paving materials has been rekindled. One of the foremost reasons for this is the potential availability of surplus sulfur recovered from secondary sources in connection with meeting environmental pollution standards (I). These sources include sulfur recovered from sour gas, from refining of petroleum, and from smelter and powerplant stack gases. Another potential saving of energy and petroleum is possible by replacing part of the asphalt binder with sulfur (2).

To consider CO2 as a feedstock, one has to consider the purity, reactivity, operational conditions, customer preferences, transportation costs, and availability of the CO2. There is a tendency by some to think that CO2 from a powerplant stack can simply be used to supply the same CO2 for chemicals production, such as the production of He by reaction of CO2 with CH4. In fact this caimot be done without a lot of purification. In the example to produce He, CO2 reforming of CH4 will doubtless need very pure CO2, that is one will have to remove SO2 or NOx fi-om the process stream. This will add cost to the CO2 for the necessary purification steps.

It is apparent that the phenomena described here are not complete processes terminating in equilibrium assemblages. The times of reaction are too short for many of the products of silicates such as clays and quartz to come to thermodynamic equilibrium at the new temperature. That this is Indeed the case in operation of powerplant boilers is obvious from the consideration of the amount of glass found in furnace slags and fly-ash.
