Great stuff.

Great work. Have you used the online QA on the dome sections as well?

Does anyone have a link to any functional test results?

I think you could make a submarine out of this 😏

I wonder how much lighter this could be if they use graphene and carbon nano tubes.

the problem is the resin temperature.

advantege versus old winding composite? You use wet fiber instead of towpreg right?

nether ... it's plastic with carbon fiber reinforcement ... that is why sonic welding joins the bits it melts the plastic ...

wow look nice but dont lose its benefits when is made by 2 parts instead of one?

Manufacturing differential with two components offers a couple of distinct advantages: e.g. quality assurance can access both sides of the laminates and the tank can be pre-equipped with sensors and devices.

yes and no is the correct answer ... yes one full one piece construction would be stronger ... BUT harder and longer to make ... doing it in bits is faster and nearly as strong ... like everything aerospace it is a trade off between function and speed and ease of manufacture ... for maximum benefit ...

Hey, let's make a submersible outta that stuff. What could go wrong?

Do you ever use Basalt fibers?

Thank you for your interest in our project! We are currently not working with Basalt fibers. Reasons for that are the comparatively low tensile modulus and the high variance in mechanical properties. Nevertheless Basalt fibers might be interesting in the future due to their natural occurrence.

​@@dlrinstituteofstructuresan6594 I believe in hydrogen much greater than batteries except in toy cars and laptops. Your videos are helpful to keep people interested. Basalt might make a good replacement for E-glass fiberglass but probably not S-glass, although it might make a useful outerlayer against the carbon fiber. I wouldn't say never on possible discovery of a better basalt fiber in the same was E-glass was improved. Because carbon fiber is conductive I wonder it's conductivity could be used in as a heat source for H2 in a metal hydride storage system? Also there might be improvements to the composite resin which would be beneficial, I'm thinking graphene mixed in, would recommend the company HydroGraph Clean Power Inc. as a possible source to experiment with graphene composites.

Hi.Can a hydrogen storage system which is 25 m long and 2.0 m in diameter be made?It is used in a boat and 200 bar pressure.

Remember, this tank does not last long. Under high pressure it's lifetime could be around 10 to 15 years. Also, it can't be recycled just like certain windmill blades. They can not be recycled. Batteries can. Also, this tank can only contain a little bit of energy. Not so much energy. Maybe for like what, 3 to 5 hydrogen cars max?

Thank you for your interest in our project! This hydrogen fuel tank is a rocket tank. The lifetime is therefore only a few minutes. A battery solution is physically not solvable.
