Wind, Solar and Hydrogen Batteries Could Power the Nation 99.9% of the Time

The biggest myth about clean power sources is that it can't provide electricity to the grid reliably enough. It's too "intermittent" say the skeptics. You know, the "wind doesn't always blow, sun doesn't always shine" stuff.

No, they could not. This is a pipe dream.

Actually it's verified science. That would be non mythical to you who do not grasp science. Though using Hydrogen batteries maybe but one of many alternatives.

Many of our power grids are in terrible condition. Something renewable must be done sooner, not later.

I am used to having power outages with some regularity--can't make it worse.

Absolutely true.

Small problem, Where is the hydrogen battery? To my knowledge it is still a variable work in progress. To extract hydrogen from water is the most feasable way to obtain hydrogen, but is exhorbantly expensive process. They are working on other ways to extract the hydrogen or to simply use water and cause a reaction to release they hydrogen.

Sure it may be expensive, but let's factor in all the costs of fossil fuel: environmental devestation, huge increase in health care costs (along with the price of human suffering), and the cost of military interventions to protect "our" oil (along with the price of massive human suffering that goes with that).

Not to mention that we need a massive green jobs program.

Of course it is possible to do away with all fossil fuels; meanwhile the Oil, Gas & Coal barons will do everything in their power to stop it. They really don't care if the planet is screwed just so long as their greed is being fed by fools like us!

Recent Talk Explores Hydrogen Energy Technology

By Shawna Williams

Jules Verne once prophesized that ‘water is the coal of the future.’ On Wednesday, March 12, Theanne Schiros (ESRB) encouraged her colleagues at SSRL to help make that happen. About 30 people came to the hour-long talk on "Scientific Challenges and Research Opportunities in Hydrogen Energy Technologies," and many stayed afterward to discuss issues raised in the talk.

SSRL Deputy Director Jo Stöhr introduced Schiros, saying that "the broader topic—the future of energy resources in the world—is an important one."

"DOE has estimated that CO2 emissions will increase 60 percent in the next 50 years," Schiros said, "with potentially dramatic climate change consequences. This is why developing alternative fuel sources, like hydrogen, is so important." Schiros said she hoped her talk would inspire some SSRL researchers to work on effective means of making and storing hydrogen.

Photoelectrolysis is a one-step process in which sunlight is absorbed in a semiconductor, splitting water into hydrogen and oxygen. This is one of the ways hydrogen can be produced and used as an inexhaustible, clean energy carrier. Hydrogen has enormous potential to form the foundation for a globally sustainable, pollution free, renewable energy system and meet growing energy demands while reducing, and eventually eliminating, CO2 and other greenhouse gases.

Hydrogen cells are already available for use in cars and in fact hydrogen fueling stations have appeared in Iceland and Southern California. However they are expensive and the current method of storing the fuel—cryogenics—is energetically inefficient. Moreover, fossil fuels are required to make the hydrogen.

There are many potential ways to make hydrogen renewably. Schiros’s own thesis work focuses using the sun’s energy to strip hydrogen from water, a process called photocatalytic decomposition. Other possibilities for hydrogen production include biomass decomposition and photobiological processes. For example, algae can be forced to make hydrogen, and decomposing peanut shells can produce hydrogen along with fertilizer while sequestering CO2 in the form of solid carbon.

A bigger problem is storage and transport of hydrogen, which is normally a gas. Some materials, including carbon nanotubes, have shown promise in absorbing and desorbing hydrogen as needed, and would take up little space. Before these can be regularly used, though, some way of making hydrogen cells from these materials cheaply and reliably must be developed.

"There are good reasons for making this effort," according to Schiros. Unlike many other energy sources, "with hydrogen cells the payoff is huge and they essentially have no negative consequences."
