Scientists Are Now Transforming Saltwater Into Hydrogen Fuel

https://www.scientificamerican.com/article/momentum-builds-for-hydrogen-fuel-in-japan-australia/
Japan and Australia are expanding their support for hydrogen fuel technology.

Hydrogen-powered automobiles will be featured at the annual Tokyo Motor Show that begins in a week. They were also featured prominently during the Group of 20 environment ministerial held in the resort community of Karuizawa. And they’ll likely be featured when the G-20 foreign ministers gather in Nagoya late next month.

Experts see positive signs for hydrogen technology investments in Asia and beyond, as governments and the private sector seek ways to lower transportation emissions.

“The hydrogen economy was first envisioned nearly 50 years ago, but it has not come to full fruition partly due to high costs and sufficient availability of alternatives,” Navigant Research said in a recent report. “In recent years, however, momentum has been building as a confluence of factors drives increased investment.”

Australia is poised to expand exports of hydrogen fuel to Japan.

The government of South Australia has approved a plan to build a hydrogen production facility near Adelaide. Some hydrogen fuel will be blended with natural gas to lower the carbon dioxide content of Australia’s distributed gas network, but the facility will also add to existing infrastructure to produce hydrogen for export.

The permit “propels the state’s status as a leader in renewable technology and a first mover in hydrogen,” said Ben Wilson, CEO of Australian Gas Networks, the company that aims to build the plant.

To the delight of environmentalists, Wilson’s company said it would use South Australia’s abundant renewable energy resources to split the hydrogen from water via proton-exchange membrane technology. Climate change activists in Australia support hydrogen as a transportation fuel but decry that much of it is produced from fossil fuels.

The new project, slated to begin hydrogen production by the middle of next year, is the latest example of the trend toward “green hydrogen.” An operation in Queensland launched exports of renewable energy-sourced hydrogen to Japan earlier this year.

South Korea has also been identified as a promising market for Australian hydrogen.

Daniel Roberts of the Commonwealth Scientific and Industrial Research Organization (CSIRO) believes hydrogen’s moment is finally arriving thanks to a “real strong global pull here for importing low-carbon hydrogen” to Japan and South Korea, where the governments have made hydrogen-based transportation “central to their energy strategy.”

Falling costs for technology and increasingly favorable economics of renewable power are also helping to spur the industry, he added.

“Key technology components, in particular fuel cells and electrolyzers, and the cost of renewable electricity coming down to a point that it’s beginning to even approach or getting to parity,” Roberts said. “Those two things have changed, which have really shifted the argument a fair bit.”

The Australian private sector is increasingly bullish about the technology’s future, despite the its government’s generally ambivalent attitude toward climate change. Even if hydrogen cars don’t take off Down Under, the rising interest in Asia is fueling a push in new investment such as the forthcoming AGN facility south of Adelaide.

“In just the past two years, the pace at which new hydrogen technologies and hydrogen fuel applications have emerged is indicative of just how important this fuel source can be for the future, including increasing reliance on renewable energy sources,” said Stuart Hawksworth, president of the International Association for Hydrogen Safety. “Clearly, it is also a fuel with enormous clean energy export potential as counties all over the world seek to increase renewables in their total energy mix.”

IS HYDROGEN ‘BACK FOR REAL’?
Japan, in particular, is determined to see hydrogen-based personal and commercial transportation succeed.

Organizers of the Tokyo Motor Show will invite audiences to tour the new Honda Clarity, the version of the sedan powered by hydrogen fuel cells. Honda says it releases no emissions, only water as a waste product.

At the Karuizawa G-20 forum, where Japan heavily promoted hydrogen vehicle technology in a stand-alone display, officials from Tokyo, the United States and European Union signed a joint statement declaring their intent to cooperate toward the emergence of mainstream hydrogen and hydrogen fuel cell technologies.

The three governments “recognize the importance of reducing the cost of hydrogen for its affordability as well as reliability,” they declared in the statement, adding that they “strongly believe that their envisaged cooperation can lead to expansion of international collaboration and contribute to scale-up hydrogen in the global economy.”

The partners clarified their goals at a follow-up gathering held in Tokyo last month. Among the visions outlined by the Japanese hosts of the Hydrogen Energy Ministerial Meeting, states will aim to see 10,000 hydrogen fueling stations and “10 million hydrogen powered systems” built within 10 years.

Look for more promising indicators and news ahead, CSIRO’s Roberts said.

“Hydrogen is back,” he said, “and I think most of us think it’s back for real.”
Maybe hydrogen cars and infrastructure will grow, I hope? Considering what scientists have recently been able to do with seawater for hydrogen, maybe these could also be a source of clean cars?
 
I apologize for bumping this but reading up on PGMPs & FGMPs, regarding the hydrogen ammo used in them, what's state of matter is the ammo in when it's lazed into becoming plasma for either weapon?

Because I was reading up on a similar PGMP in an ATU, called HOSTILE, and there the weapon uses "cadmium-telluride pellets" as the ammo source to be lazed for the plasma weapon there.
 
I imagine this process would allow for a huge amount of hydrogen to be extracted from anynplace with liquid water or ice right?

That's the idea--but then, the theory that allows someone to develop a new technology doesn't always point out where the technique fails . . .

That is, there might be limits not initially obvious. Like the limits on basic electrolysis, especially in the presence of high Cl- ions.
 
Few if any of these studies consider the carbon footprint and pollution of manufacture of batteries. None consider decommissioning of batteries.


One study that did look at manufacturing of batteries calculated that the carbon emissions exceeded typical gasoline ICE engine manufacture by the equivalent of 8 years driving the ICE engine version.

What's the carbon footprint of a battery built in a plant powered by solar/wind/hydro?
 
What is the carbon footprint of the manufacture of said solar/wind/hydro generation that stores the energy is the battery. What is the carbon footprint of manufacturing the batteries.
This is what the green lobby lie about all of the time - there is no such thing as a free lunch.

There is also the environmental effect (carbon footprint, as well as other abhorred effects like on river biome) of manufacturing, say, the wind turbines or solar panels or the dams to have the generative capacity. I've rarely seen these addressed--"electric cars" are simply assumed to be "zero emission"--but how the electricity is produced is neatly ignored.

No there isn't but this didn't answer the question.

And, I haven't the slightest idea, which is why I ask.

Since EVERYTHING, currently, is based on the carbon economy, then everything has a carbon footprint of some kind.

But, that carbon economy can be invested in to resources that allow production WITHOUT, or with notably less, of a carbon footprint.

The question is whether that initial investment will net out to an overall carbon reduction in time.

If it takes 100 Carbon Units to produce 20 Solar units, but then those 20 Solar Units can create another 200 Solar Units over time, is that a reduction of 1000 Carbon Units? And what of the output from those derivate 200 Solar Units?

Obviously, not everything is carbon footprint. Raw energy is not the sole resource necessary. But is the trade of carbon footprint today for, say, an expanded, longer term toxic waste footprint a good trade?
