Hydrogen is a useful gas. Whether you want to float an airship ... that also produces useful heat and oxygen as byproducts. The key to the process? Concentrated sunshine. With an eye to producing ...

“Using renewable electricity, 75 percent of that energy makes it to the wheels of a BEV,” says James Edmondson, research ...

When yeast was added to hydrogen peroxide, a chemical in the yeast causes a reaction in which the hydrogen peroxide breaks apart to form oxygen gas and water. The oxygen was in the bubbles you saw.

because it won’t react with the oxygen in the air. Some metals react with water, but others don’t. When a metal reacts with water, hydrogen gas is produced and this can catch on fire.

Just about everyone knows that water is H2O, meaning two hydrogen atoms and ... space environments using gases and metal catalysts, without requiring extreme reaction conditions.” ...

Automated hydrogen ... and oxygen. With this system it’s easy to measure the volume of the produced hydrogen due to the displaced water in the bell. Once enough hydrogen gas is produced, a ...

Inhalation of 2% hydrogen gas improves survival rates in emergency treatment Hydrogen reduced cell death (shown in red) from reactive oxygen species In Japan, over 140,000 people are rushed to the ...

Hydrogen peroxide decomposes on its own into water and oxygen gas. This process is sped up by a catalyst. In this reaction, the catalyst is potassium permanganate, and the bubbles are full of oxygen ...

acid and oxygen. The reactivity of the metal determines which reactions the metal participates in. When metals react with water, metal hydroxides and hydrogen gas are formed. This can be ...

German chemicals firm Evonik has signed a term sheet with hydrogen specialist VoltH2 to build a 50MW electrolyser at the Delfzijl chemical park in the Netherlands.
