PIEL® Hydrogen Generator
Current Applications
1.        Iron sheet shearing (steel plates cutting)
a)      Method
Instead of propane gas, natural gas, acetylene gas and so on as heat source to cut iron sheets, Hydrogen gas can be used.
b)        Merits

i)     Cutting speed to be much quicker by approx. 30% or more

ii)     Piercing time to be much shorter by approx. 50% or more
iii)    Cut finish to be much smoother
iv)    Sludge left to the cut sheet to be easily removed
v)    Gas utility cost to be much smaller
vi)    CO2 gas emission to be far less
c)         Mechanism
i)      When propane gas burns to produce enough heat to cut iron sheets, the propane gas consumes almost 3-5 times volume oxygen. However, in the case of hydrogen, the volume of oxygen to be consumed is the half of the hydrogen (2H2+O2=2H2O), thus total consumption of oxygen can be far less. Therefore total cost of gases for heating is much smaller.
ii)      In addition, because the cutting speed by H2 gas heating is quicker by approx. 30%, the oxygen to be used for cutting (=cutting oxygen) can be less by approx. 30%. Thus, heating gas and cutting oxygen both can be saved.
iii)     Heat by hydrogen can be much concentrated in comparison to those of other combustion gases such as propane, natural gas and so on, thus only the place to be cut is being heated. Therefore, mal-effects by the heat to other parts not to be cut are very small. This can have a positive effect that sludge left to the cut sheet, if any, can be easily removed because the sludge is not melted and glued to the cut sheet. In addition, bent-over by hydrogen gas heat will be far less in comparison to other gases.   
2.        Blazing (soldering)
a)   Method
Instead of acetylene, propane and other combustion gases to be used for blazing, Hydrogen gas can be used for better quality and cheaper utility cost.
b)   Merits
i)   PIEL Hydrogen Generator produces Hydrogen and Oxygen separately on-site. When the Hydrogen burns, the Oxygen produced can be used, thus no extra oxygen will be required. Therefore, total gas cost can be much less.
ii)   Because no combustion gas such as acetylene is stocked in case of PIEL Hydrogen Generator, safety at the production line will be dramatically enhanced. On the other hand, acetylene gas, for example, can easily burst even in case the cylinder just fall down.
iii)   Hydrogen will not produce CO2 gases when burns, thus is much friendly to environments.
3.        Cooling material for shaft between turbine and alternator at power plants
Electric Power Development Corporation in Japan has adopted PIEL Hydrogen Generator to supply on-site 99.99% purity hydrogen gas to main line of Matsushima Power Plant in Kyushu, which has an electricity generating capacity of 500,000 kW or more. The hydrogen gas is being utilised as the material to absorb heat to be produced when shaft rotates at the very high speed, which connects turbine and alternator.
a)   Merits
I)   Hydrogen gas cost can be cheaper because the hydrogen is being produced on-site, which does not require a long-distance transportation.
ii)   Safety can be enhanced because less amount of hydrogen gas is now stocked in cylinders at the site.
Other Applications
Under the current circumstances, it is very difficult to stock electricity. If PIEL Hydrogen Generator is adopted , however, the electricity to be diminished can be saved in the shape of Hydrogen gas after electrolysis process. Oxygen can be also available. Under the proposed system, power plants can level their electricity production, thus the power plant management will become more efficient. The stocked hydrogen can be used to produce electricity again by fuel cell. In addition, the following areas are to be expected as the fields of hydrogen gas usage:
i)    Automobiles for both fuel cell and combustion engine type (PIEL already has a line up of hydrogen gas combustion engine car)
ii)    Toxic waste gas to be used on the process of semi-conductor production, can be decomposed by hydrogen and oxygen burning.
iii)    Sludges and ashes which are left after garbages are burnt, can be finally melted by hydrogen and oxygen burning and will become almost 1/3-1/10 in quantity and almost no toxic ingredients. It will help more effective use of dumping areas with much safety.
