Researchers claim to have built Europe's first 'zero-emission' house powered by hydrogen
The hydrogen-powered fuel cells generate the electricity and heating required to meet the building's needs.

Researchers in Italy claim to have built Europe's first house powered by hydrogen fuel cells.

This solution was developed by scientists at the University of Sannio in southern Italy in collaboration with private companies, Euronews reported on Thursday.

"Lately, we have focussed on the issue of CO2 emissions in the environment and worked on the idea of using hydrogen to make this house a completely self-sufficient system," Gerardo Canfora, the dean of the University of Sannio, told Euronews.

Isn't hydrogen a very flammable gas that can cause fires and explosions? How have they addressed that issue?

A great idea if it works.
Otherwise it’s here today and gone tomorrow.

Isn’t natural gas flammable

liberalhunter Loc: Your mom's house

Not new or interesting...... and BOOM is an issue.

BOOM.... If something will not explode, it will not be able to power an engine..

If gasoline had to pass a safety test back in the day.. it never would have become the power source of of choice..

Same as natural gas ?

So we would still be riding horses?

It seems that the bunch of you have learned to h**e Hydrogen as well as windmills and solar panels..

what a lost group..

Pros and cons to the use of hydrogen gas in homes.

https://www.energy.gov/eere/fuelcells/safe-use-hydrogen

By their nature, all fuels have some degree of danger associated with them. The safe use of any fuel focuses on preventing situations where the three combustion factors—ignition source (spark or heat), oxidant (air), and fuel—are present. With a thorough understanding of fuel properties, we can design fuel systems with appropriate engineering controls and establish guidelines to enable the safe handling and use of a fuel.

A number of hydrogen's properties make it safer to handle and use than the fuels commonly used today. For example, hydrogen is non-toxic. In addition, because hydrogen is much lighter than air, it dissipates rapidly when it is released, allowing for relatively rapid dispersal of the fuel in case of a leak.

Some of hydrogen's properties require additional engineering controls to enable its safe use. Specifically, hydrogen has a wide range of flammable concentrations in air and lower ignition energy than gasoline or natural gas, which means it can ignite more easily. Consequently, adequate ventilation and leak detection are important elements in the design of safe hydrogen systems. Because hydrogen burns with a nearly invisible flame, special flame detectors are required.

In addition, some metals can become brittle when exposed to hydrogen, so selecting appropriate materials is important to the design of safe hydrogen systems. In addition to designing safety features into hydrogen systems, training in safe hydrogen handling practices is a key element for ensuring the safe use of hydrogen. In addition, testing of hydrogen systems—tank leak tests, garage leak simulations, and hydrogen tank drop tests—shows that hydrogen can be produced, stored, and dispensed safely.

As more and more hydrogen demonstrations get underway, hydrogen's safety record can grow and build confidence that hydrogen can be as safe as the fuels in widespread use today.

Hydrogen gas = BOOM; Helium gas = pop

The 1930's was the golden age of the lighter than air ships. America at that time had the almost only source of helium gas and filled its airships with helium. The rest of the world used hydrogen gas to fly their airships. Germany had a great fleet of ships flying across the Atlantic Ocean to North and South American countries. A good safety record also. Then came 1937 and the crash of the Hindenburg. The biggest disaster (sarcasm) of aviation history. Passengers and crew 97, dead 36, survivors 61. Today’s airplane crashes often are 100% dead with 0% surviving. However we as humans often are biased by news reports or other external inputs. We ride in airplanes but shun airships. We still fear hydrogen gas because of the Hindenburg.

Again, just my perspective.

good article... I may have been wrong about who opposes the development of hydrogen use.. It has long been a favorite of mine for usage.. have seen a few vehicles powered by hydrogen..

permafrost Loc: Minnesota

Think you are correct.. thanks for the reminder.. as for airships. short time ago ran across an article of them being used again.. think it was a short distance,, like London to Paris.. wish I could recall where I saw it.. would be nice to have a link, but I come up with nothing..

Wasn't the Hindenburg filled with 7 million cubic feet of HIGHLY COMBUSTIBLE hydrogen gas? The result...

They have a place in t***sportation. I don't believe they will be cost effective as they are quite labor intensive. Big ground crews to land. Sort of like the times I got to be fireman on a friends steam crane. I made some comment and he said that it required two people to operate a steam crane while a diesel d**gline only required one operator. The amount of fuel was about equal but the steam crane used several hundred gallons of water a day. He also owned a steam shovel and I was fireman on it once. We burned three cords of firewood to put in a culvert across a road. Took all morning where a backhoe would have taken about a half hour.
