Once electricity has been used to produce hydrogen fuel, the gas must then be stored so that it can be used when needed. It can be stored as either a gas or as liquid H2 (LH2). As a gas, it typically requires high-pressure tanks (350–700 bar [5,000–10,000 psi] tank pressure...
Worldwide, hydropower plants produce about 24 percent of the world's electricity and supply more than 1 billion people with power. The world's hydropower plants output a combined total of 675,000 megawatts, the energy equivalent of 3.6 billion barrels of oil, according to the National Renewable...
摘要: Bringing together technological experts and policy makers to determine what a hydrogen economy may look like and how it may benefit society, "The Hydrogen Economy: Its Impact on the Future of Electricity" conference will be held April 19-20, 2004 at the JW Marriott Hotel in Washington....
Scientists have created a catalyst they believe can radically reduce the price needed to create hydrogen.
Although fuel processors can provide hydrogen gas to a fuel cell while producing much less pollution than an internal combustion engine, they still produce a significant amount of carbon dioxide (CO2). Although this gas is not a regulated pollutant, it is suspected of contributing to global warmin...
Just a year ago, few people took seriously the idea that we could extract hydrogen from the ground as a clean energy source - but now the US Department of Energy is injecting $20 million into the concept

Hydrogen removes heat from the generator and transfers it through a heat exchanger into a secondary cooling circuit that contains de-mineralized water as a coolant. This is why very large generators and small power plants often have large cooling towers next to them. For all other common ...
advanced electrolyser projects planned by 2030, although many of these will also have to feed into large-scale demand not only to displace grey hydrogen in existing sectors, but to produce e-fuels for the aviation industry. However, if early-stage concepts are counted, the pipeline rises to ...
