The Hindenburg disaster is an example of a large hydrogen explosion. Hydrogen safety covers the safe production, handling and use of hydrogen, particularly hydrogen gas fuel and liquid hydrogen. Hydrogen possesses the NFPA 704's highest rating of four on the flammability scale because it is flammable when mixed even in small amounts with ...
Earth’s subsurface holds trillions of tonnes of hydrogen gas, enough to fuel human activities for nearly 200 years and break our dependence on fossil fuels, a new study suggests.
1929 – The hydrogen-filled LZ 127 Graf Zeppelin makes a 33,234 km (20,651 mi; 17,945 nmi) circumnavigation of the world. It is the first and only airship to do so, and the second circumnavigation of the globe by air. The voyage took a total of 21 days, 5 hours, and 31 minutes.
As COVID-19 starts to take up less of the world's attention, the issue of climate change and green energy is growing. It's impossible to ignore the impact of fossil fuels and pollution on our ...
Hydrogen fuel cell cars like the Toyota Mirai contain Kevlar-armored tanks that store hydrogen at 700 times the pressure of the Earth’s atmosphere. But this is hard to do on a large scale for ...
Hydrogen is a chemical element; it has symbol H and atomic number 1. It is the lightest element and, at standard conditions, is a gas of diatomic molecules with the formula H 2, sometimes called dihydrogen, [11] hydrogen gas, molecular hydrogen, or simply hydrogen. It is colorless, odorless, [12] non-toxic, and highly combustible.
Hydrogen picked up during melting and casting segregates at internal voids and discontinuities and produces these defects during forging. Fish-eyes are bright patches named for their appearance seen on fracture surfaces, generally of weldments. Hydrogen enters the metal during fusion-welding and produces this defect during subsequent stressing.
Even so, SocalGas says other states and countries have used hydrogen fuel in home appliances and reduced emissions, such as in Hawaii and Canada. The state sees hydrogen fuel as crucial to scaling ...
