Sentences with phrase «hydrogen at low pressure»
«We need a cheap, porous material to store and release hydrogen at low pressure and at room temperature, and it needs to be a reversible process, for when the tank needs to be refilled,» he says, adding that he and his colleagues are working on a business plan that will help them commercialize their work.

Diamonds, low temperatures and pressures way above what's found at Earth's centre were used to create a form of hydrogen foreseen back in the 1930s
At a lower pressure — approximately 4 GPa — methane and molecular hydrogen interact, forming co-crystals (where two molecules together create one crystal structure), and at 6 GPa, hydrates — CO-crystals made of methane and water — are formeAt a lower pressure — approximately 4 GPa — methane and molecular hydrogen interact, forming co-crystals (where two molecules together create one crystal structure), and at 6 GPa, hydrates — CO-crystals made of methane and water — are formeat 6 GPa, hydrates — CO-crystals made of methane and water — are formed.
Typical systems take hydrogen input at a low pressure (7 — 20 bar) and compress in two stages (7 bar - 400 bar - 875 bar) to reach their target pressure for either fueling material handling equipment (400 bar) or light - duty fuel cell electric vehicles (875 bar).
Why it matters: At high pressures and low temperatures, like those found in permafrost or on the ocean's floor, water molecules organize into complex hydrate lattices that are held together by hydrogen bonds.
By filling part of the tank with a MOF's cagelike network built with hydrogen - absorbent metal hubs and organic struts, however, it is possible — at least in theory — to store more of the gas at a lower pressure.
To their surprise, the titanium augmented sodium alanate's capabilities as a storage system - lowering the temperature at which hydrogen was released, making the process much more efficient, while allowing for easier refueling and storage of high - density hydrogen at more conventional pressures and temperatures.The result: a near - doubling of the stored gas» weight - percent when compared to other cheap materials.
