Onboard generation

The challenge for onboard generation of hydrogen is no less monumental. To be competitive with the internal combustion engine, the fuel cell engine must cost approximately 3,000. This means that for a 100 kW power source the onboard... 

Critically important to an understanding of this event is the fact that Piper Alpha was a hub platform. Not only did the platform have its own risers, it also received gas from the Tartan A platform, which was located about 11.5 miles away. The gas flowed to Piper Alpha through a subsea 18-inch pipeline. This gas stream was combined with Piper s own gas, compressed, and sent to the MCP-01 platform, some 33.5 miles away. Some of the gas was also used as lift gas and as fuel for the onboard generators (the gas could also be flared). In addition, another platform—Claymore—could also feed gas to Piper Alpha. All of the platforms were operated by the same company—Occidental.

Methanol is formed by reacting carbon monoxide with hydrogen. (This might be an onboard generation of hydrogen for the hydrogen economy.) With the reaction... 

Parsons adopted this multistage design to reduce turbine operating speeds to a useful level. His initial turbine was developed to produce electricity onboard ships and had an output of about 7 kW. In 1888 he designed the first steam turbine generating unit for public utility sei-vicc. By the time of his death in 1931, his company manufactured turbines generating more than. 30,000 kW. 

In an irreversible metal hydride, hydrogen is generated through a chemical reaction, which is not easily reversible onboard a vehicle. Common reactant is water or an alcohol. For example, sodium borohydride can produce hydrogen as... 

Others affirm the superiority of direct hydrogen, but feel that liquid fuels such as methanol are the answer for the near future. If methanol is used directly, there has to be an onboard reformer and a revised infrastructure to deliver it. But methanol does have some advantages. There is excess generating capacity, and it s the least expensive fuel to transport. Some 70% of the world s oil is in OPEC countries, and 65% of it is in the Persian Gulf. If we switch to methanol, which is produced from natural gas, we can diminish that dependency. 

For the past few decades, manufacturers have been streamlining components and installing onboard computers to hit the propeller blades for maximum efficiency for the wind conditions. In the 1980s, the average turbine was 20 meters high with a 26-kilowatt (kW) generator and a rotor diameter of 10.5 meters. A typical turbine today can be 55 meters high, with a rotor diameter of 50 meters and a capacity of 1.6-MW. The power it produces may supply 500 homes. 

One of the initial attempts of exhaust gas reforming, as well as onboard H2 generation, was reported by Newkirk and Abel. Their process of high-temperature, non-catalytic SR of gasoline resulted in carbon formation in the reformer however, their objective, to reduce emissions by feeding H2 to the gasoline engine, was achieved. 

In an early investigation on fuel cell applications, Callahan studied catalyzed pyrolysis of various hydrocarbon fuels (combat gasoline, Sunoco 190 gasoline, JP-4 jet fuel, and diesel fuel) for onboard H2 generation. Ni supported on...
