Efficient Danes use hydrogen cells to maximize wind power

Watch all the videos from Worldfocus’ signature series: Green Energy in Denmark.

Last week, we showed you how everyday Danes profit from pioneering wind power. But there’s a challenge — how to store that power when the wind isn’t blowing, or in the case of solar power, when the sun isn’t shining.

Denmark is searching for answers, including building Europe’s first “hydrogen neighborhood” — homes that are powered and heated with the help of hydrogen fuel cells. John Larson reports from Denmark.

Wow, this is AmaZZZing show about Wind Power! I live in Hayward, California and I want my city to invest in co-op to set up wind turbines just like they to it in Netherlands. Geologically my city is perfect because it’s very small almost like a town and we have high hill areas to set up wind turbines. I think it will be very good for the residents in the city and for the city as well because we can sell the electricity to other neighboring cities. I just need help on how to go about it on how to organize such enormous project. Where can I find support? I know it will pay itself off in the long run. Thank you World Focus. I wish you guys would stay in business and continue to broadcast. This was an eye opening.

My Grandfather was born in Nordby, Samsoe in 1880 so I was thrilled to see this show. How can I get a DVD of the program? As an energy puchasing manager for over 30 years I admire the Danish willingness to “bite the bullit” by forcing gasoline prices to high levels. We Americans do not have politicians with the foresite or guts to do what is so oviously the solution to foreign oil dependency.

WOW – what a great documentary!! Let’s all share this with as many others as possible. We’ve got so much to learn – and the Danes have proven that it can be done!!!

The quality of the info is what keeps me on this site, thanks!

Wish You a Merry Christmas. :)

hydrogen generator
Agreed. I see many people building their own hydrogen generators to save money on gas bills. Seems like the trend is gonna rise soon and most of us would be running our cars on water.

I am perplexed by the comments that precede mine. I agree and disagree with each of them, but it is a fine dialog. As I see it, economic dispatch (defined well by Carl Todd)is not a clear reality at all, for renewables government favor – special tariffs in Europe and tax credits plus mandated use in North America – upset the balance of incremental and decremental auctions for power, which occur at least hourly in all advanced grid systems. As Joseph Somsel once noted, if you have to store electricity and lose half in the process, isn’t it better to store the cheapest electricity you can? In North America, wind energy is far from the cheapest. also note that countries with the most wind energy infrastructure have the highest electricity rates, but which is the cart and which the horse?

There is no doubt that the lowest cost source of heat and electric will dominate which is used in a given locality. As existing lower cost supplies diminish from natural caused or over use the next lower cost source will take its place , and so on.

When one’s needs for energy covers a wider range than a single locality that users choice is first governed by universal availability and then cost.

In all cases cost is not just that of the fuel but included therein is the cost of the equipment its age life and maintenance when the final financial decision is made.

Cost effectiveness is a flexible term dependent upon your variables. When you have so much local electricity you have to pay other people to take it from you (as they do in many parts of Denmark) cost effectiveness is a different question. Which, btw, was the point of the story. Also, the efficiencies of the processes are being improved, the back half of electrical generation is now approaching 80 percent efficient. Dead end? Hardly.

Hydrogen Fuelcells have been around for decades,perhaps a century or so,…unfortunately they are not cost effective/efficient,period. Their use in the States over the last twenty years have been for alternate back-up power due to power outages. They are primarily used at hospitals for the sole reason of supplying electrical energy as long as their fuel consumption isn’t disrupted. They are superior to a power generator dependent on volatile distillate fuels. Fuelcell Inc. Ct/USA,and Ballard Power Inc./Canada are the premier state-of-the-arts manufactuers of Hydrogen Fuelcell’s,which both use propane as their energy source. It’s a dead-end venture,especilly when it comes to hydrogen vehicles. (Note: Ballard does have fleets of mass transit bus transpotation ,and fueling station located throughout the states as prototype’s for mass production,…but the infrastructure,and establishing regulatory standards is in limbo. There are better alternatives… like a state-of-the-art electrical grid to get the best bang for the buck.

There must be a catch in the solution. If it was that simple wouldn’t there have been a “get rich quick” scheme already?
