The zero energy solution

I found this article about a solution when excess solar energy is used to create hydrogen gas.
A schedule to show the working principle:

A barn-size array of solar panels collects energy from the sun and converts it to electricity. An electrolyzer runs any excess electricity through water to produce hydrogen gas, which can then be stored for later use. The gas can fuel an experimental hydrogen car. Or it can be converted back to electricity whenever extra power is needed to light or heat the family home.

I believe there are possibilities with techologies like this one. Do you guys agree?

Safe storage of hydrogen gas

We have been discussing the dangers of hydrogen gas and everyone realizes that a safe storage is necessary.
The safe storage of the hydrogen gas is indeed a bottleneck in the evolution of the hydrogen powered car.
Therefore a lot of research is done to create a solution.
There has been a multi-year project done by Batelle. (Battelle has for decades served as an integral resource for developing safety test methods for new vehicle technology.)

In their report, they make the following statements

In the tests that we’ve performed—and this is crash tests of some mockup hydrogen vehicles as well as crash tests of actual hydrogen fuel cell vehicles—in all cases the container, the tank and the fuel system remained leak tight. This was despite impacts to the tank itself, in crashes rear and side up to 40 mph. So this was impacts to the fuel tank region. The tanks were well protected—the vehicle provides substantial protection. Then, the tanks, being high pressure tanks, are extremely robust in a crash scenario. In addition, there is plumbing and the fittings that convey the gas. Those were deformed substantially. They are very ductile and can accommodate the deformation that occurs in a crash without leakage.

—Dr. Denny Stephens

Battelle test results suggest that, with appropriate safety testing, hydrogen vehicles can be as safe as conventional vehicles on the road today.
Would you consider buying a hydrogen car when it is as safe as a conventional vehicle?
I would.

Hydrogen used in fuel cells for submarines

As some of you probably now, we have been on a study trip to Copenhagen.
During one of our company visits we were introduced in the world of submarines.
During this company visit they told us they used fuel cells working on hydrogen gas in order to double their range.

Since these fuel  cells came very close to our thesis subject it was very interesting to see.
I wanted to share this with you because it is yet another use of the hydrogen gas.

The danger of hydrogen gas

As we all now, hydrogen is the simplest element on earth. The gas  has a lot of energy.
Hydrogen burns clean, unlike most other fuels that emit carbon when on fire, like gasoline and diesel.
This makes it a very useful source of energy but off course this also has a disadvantage:
When you do not take extreme precautions when handling the gas, it can be very dangerous to use it.
This is also shown by fact that the H-bomb is one of the most devastating weapons created by man.
This leads to fears about using hydrogen in our daily lives.

In our thesis we do not have these problems with the hydrogen gas because it is not stored but made on the moment itself.
Off course we make sure everything is connected correctly and that there are no leaks possible.

What do you think of the dangers of hydrogen gas?



The solution? Combining..

I ran into this movie about a car that runs on hydrogen, natural gas and gasoline.

We were discussing the advantages of each concept seperatly. But maybe the solution is indeed a combination of different power supplies.

Do you think this could be a solution?


Hydrogen vehicles: The end of the electric car?

I read this article about the use of hydrogen vehicles.

I put some of the statements here:

1) Hydrogen vehicles are free of the ‘range anxiety’  that electric cars have. Their range is almost equal to the range of gasoline powered engines.

2)The tanks of a hydrogen car can be filled in minutes in stead of hours with the electric car.

3)A disadvantage is that there is no infrastructure yet. But as always this is like the chicken-and-egg problem

4) When using hydrogen one has to be very careful and make sure there are no leaks possible. Also corrosion is a possible threat.

5) Hydrogen has to be made like electricity as it does not occur in nature in useful quantities.

6) There is no pollution with a hydrogen car as the only thing coming out of the exhaust is water.

7) When using hydrogen you do not have the disadvantages of a the battery of the electric car. (expensive, rare earth minerals, etc)

If you want you can read the entire article here:
I do not mention the part where they discuss the use of nitrogen gas because it is not relevant for the question I have for you.

Do you think hydrogen cars could become a standard in the race for a non-polluting car instead of the electric car?
They both have some advantages and disadvantages.

I’m looking forward to you reactions.


Using the HHO generator for welding.

As we see in this movie, it would be perfectly possible to use a HHO generator like the one we are building in a welding application. We would only have to do a few changes in the design.
The welding machine in the movie works also at 10-15 amps, like our machine.

As you can see there are a lot of applications possible with a HHO generator.
Does anyone has other idea’s about the use of HHO-gas? Let us know.
