There are popular misconceptions about "green" hydrogen power.
avatar July 11, 2018 07:36PM
The most expensive way possible to create hydrogen is to use electricity to split apart water molecules. Factor in the carbon emissions from power plants needed to do that. Commercially hydrogen is produced by chemically splitting it from carbon in natural gas.

Hydrogen fuel cells

Pros: No vehicle emissions other than water vapor. Fuel economy equivalent to about twice that of gasoline vehicles. Hydrogen is abundant, and can be made from renewable energy.
Cons: This space-age technology is expensive. Acceptable range requires extremely-high-pressure, on-board hydrogen storage. Few places to refuel. Hydrogen is very expensive to transport and there is no infrastructure in place yet. Currently hydrogen fuel is made from nonrenewable natural gas in a process that creates enormous CO2 emissions.

Just burn the natural gas instead.

Then again, hydrogen isn't always clean to produce. It's expensive to pull hydrogen from water. Non-renewable sources of hydrogen, such as oil and natural gas, are much cheaper, but using them still puts a drain on our fossil fuels supplies. Ironically, the carbon dioxide released in the process of producing hydrogen from fossil fuels cancels out any benefits to the environment. Experts say hydrogen that escapes during the production process could erode the ozone layer even further and exacerbate global warming [source: PBS]. There are other problems as well: Scientists are still struggling with the challenge of how to store hydrogen. Because it has such a low energy density, hydrogen needs to be stored and transported under high pressure -- which makes it bulky and impractical. The pressure issue compounds another issue with hydrogen energy; like gasoline, hydrogen is highly flammable, but unlike gas, it has no smell. Sensors must be used to detect a leak before hydrogen can combust. Another issue is the need to provide enough refueling stations to supply all the hydrogen-powered cars throughout the country. Are hydrogen fuel producers willing to put a hydrogen station on virtually every corner?

Off TopicEek! About 1 hour ago there was a huge gas-line explosion in my childhood neighborhood. Jpeg Attachments BF Hammer 133 July 10, 2018 05:10PM
That's Crazy, Chris! I know I've been there, glad you're ok. jhargrave 67 July 11, 2018 02:18PM
Thanks! I've looked at the reports today, some of the standing structures are just burned-out shells right now. BF Hammer 61 July 11, 2018 02:35PM
I bet! I haven't seen that, just your info and the story in the Janesville Gazette this morning... jhargrave 60 July 11, 2018 02:39PM
Let me put this city disaster in perspective here... Jpeg Attachments BF Hammer 90 July 11, 2018 08:55AM

Ugh. I just heard about the firefighter who was killed. Sad God bless him and his family. (n/t) Zeb 65 July 11, 2018 09:42AM
That's close. The explosion was reported on the national news this morning. JohnSNY 59 July 11, 2018 09:42AM
So sad Sad Glad you are ok. (n/t) Dbyers 63 July 11, 2018 07:29AM
Glad to hear your ok Smile Thats bad Sad (n/t) MarkKershaw 56 July 11, 2018 06:59AM
Glad to hear you're okay. Gas scares me. (n/t) svorkoetter 60 July 11, 2018 05:15AM
Glad, you're OK, Chris. Since our country is all gas heating (but now wants to change) we hear every now and then of explosions. James T. Kirk© 68 July 11, 2018 01:38AM
What do they want to change to? (n/t) svorkoetter 59 July 11, 2018 05:16AM
Everything electric, solar panels, (hybrid) heat pumps, etc... James T. Kirk© 65 July 11, 2018 08:26AM
That's good to hear. svorkoetter 63 July 11, 2018 10:32AM
That' cool. There are idea's about hydrogen gas as well. I think it would be the best idea for cars... James T. Kirk© 64 July 11, 2018 03:10PM

Splitting hydrogen out of water with green electricity would be green. svorkoetter 62 July 12, 2018 02:21AM
That sucks. Sad (n/t) Zeb 65 July 10, 2018 07:11PM

Now I just was notified by phone to evacuate my home. Signing out. (n/t) BF Hammer 57 July 10, 2018 06:00PM
Relocated to my sister's home. The are still working on shutting off gas. (n/t) BF Hammer 61 July 10, 2018 06:51PM
And now back home OK. Unsure if I have gas at my house currently. BF Hammer 63 July 10, 2018 08:29PM
Would I turn on this gas if my friend Chris was in there? LOL Video Attachments Zeb 66 July 10, 2018 08:52PM

Sorry to hear, no fun... BobbyMikeRedux 64 July 10, 2018 08:48PM
Eek! Gas sure can be dangerous. On the news a couple days ago there was a hell of a blast ...... Robmks 70 July 10, 2018 05:32PM
