Siemens plans electrolyzer system to store wind power as hydrogen.

Siemens plans electrolyzer system to store wind power as hydrogen.
05/16/2014 By Editors of Electric Light & Power/ POWERGRID International



In the German city of Mainz, Siemens, together with the public utilities of Mainz, Linde and the RheinMain University of Applied Sciences, has laid the foundation stone for a new type of energy storage system.

From spring 2015, the system, equipped with an electrolyzer from Siemens, will convert surplus electricity from wind farms to hydrogen. The hydrogen will then be stored locally in tankers or fed directly into the natural gas grid for subsequent power or heat generation.



In this way, it will be possible to store electricity from renewable sources over longer periods of time. The tankers will also be able to supply the growing network of hydrogen filling stations for emission-free fuel-cell vehicles....

Toyota fires bullets into hydrogen fuel tanks

With some industry members and analysts questioning both the viability and durability of hydrogen fuel-cell electric vehicles, Toyota executive Bob Carter, speaking at the Automotive News World Congress this week, says the Japanese automaker went all Clint Eastwood on the fuel tanks of a fuel-cell prototype. Carter says that bullets from a small-caliber gun bounced off the carbon-fiber tanks, and that .50-caliber bullets barely made dents...

You seem to be saying that you can't make a tank out of something that has 'larger' atoms than what it is trying to contain. If that were true, then you couldn't contain Oxygen, which has an atomic weight of 8, using a tank made out of Iron, which has an atomic weight of 26. I'm pretty sure that is not true...

Molecular hydrogen leaks slowly from most containment vessels.

http://en.wikipedia.org/wiki/Hydrogen_economy

H has a molecular weight of 2.016

O is 3.25 times less than Iron, H is nearly 13 times less than Fe. H will fit in between FE molecules, O wont.

This is easily googelable, I'm not sure why it needs to be documented.

19. The size of the atoms isn't the big problem
Sun Jun 1, 2014, 06:07 PM

Hydrogen embrittles metals and degrades rubber seals.

The other problem: the only way to do serious bulk storage of hydrogen is to liquify it. That carries its own problems. (I was following a truck loaded with liquid H2 one fine day...there was a sign on the back of the truck "venting of gas from the top of this truck is normal.&quot

If they were to stick me with the task of storing wind energy chemically, I'd find the closest factory to my wind farm and buy its CO2 emissions. I would then install a recovery unit in their smokestacks and pipe the CO2 to my facility...where the hydrogen created from wind-driven electrolysis will go to make methane - which CAN be dumped into the national natural gas network. If you really want hydrogen you can pipe the methane to the point of use and steam-reform it there. (And of course if you build your pipe network with a series of return pipes, you can ship the CO and CO2 created by the reformation reaction back to me and I'll just put it right back in the process.)

... is almost as good as throwing away.

You could, however, use the hydrogen to turn Carbon Dioxide into Methane, something the gas pipelines were designed to carry.

Molecular hydrogen leaks thru most containment, it must be used quickly, so the key to making this work is too produce the hydrogen at filling stations.

Why are so many people pretending to know so much about that which they clearly know nothing about?



Project Overview
It’s the kind of massive project only a global leader would undertake.
Anticipating that hydrogen needs along the Gulf Coast of North America will increase in the years ahead, Air Products expanded its hydrogen supply network.

By building a 180-mile (290-km) pipeline that connects our existing Texas and Louisiana systems, we’ve united 22 hydrogen plants and 600 miles (965 km) of pipeline, with a total capacity of over one billion SCFD (1.3 million Nm3/hr).

So if an event disrupts operations on one side of the Gulf, hydrogen can keep flowing from the other, giving our refinery and petrochemical customers the reliable, uninterrupted supply they need. With this record-breaking network, Air Products continues to break new ground in hydrogen supply.

15. Hydrogen pipelines built for the oil industry.

Hydrogen is useful stuff for turning tar into gasoline and diesel fuel.

But it's not something you can simply dump into the U.S.A.'s often decrepit, methane/ethane/other_crap gas network.

The U.S.A. is more like Russia than Germany in that respect.

I hate personal automobiles anyways. I don't care how they are powered.

In a rational society people walk, pedal, sail, or ride electric rails.

thru any pipelines"

That is just simply false. And these pipelines can service hydrogen stations just as easily as they can service the oil industry.

I really don't get your entire philosophy anyway, you seem hell bent on bashing a clean, renewable, cheap way to get off of oil but here is what you have stated regarding nuclear power (you didn't answer before but search works)

I'm now in a place where I am adamantly against fossil fuels, automobiles, and our consumer society. I'm essentially indifferent to nuclear power.

And this is after the recent lesson of Fukushima. Incredible.

Well there's no need for fission to boil water anymore with decentralized Hydrogen. The next few years will make that as clear as a bell.

You were wrong. It's just that simple.

And you keep talking about not being able to store hydrogen but Honda's fuel cell vehicle has been on the road since 1999 and if there had been any problems the anti hydrogen people would have made them well known.

GM's fleet of hydrogen test vehicles has been operating for 7 years and there have been no reported problems.

You really think Hyundai, Honda and Toyota would introduce hydrogen vehicles with tanks that lose their gas ?

Storage of hydrogen is problematic, I have documented that, repeatedly. Put hydrogen in a car and drive the car the hydrogen is depleted before a significant quantity is lost.

A hydrogen infrastructure for cars does not, will not resemble the infrastructure for gas.
