Why is hydrogen fuel so appealing? Hydrogen fuel, particularly green H2, is an appealing form of renewable energy for a number of reasons. It is highly abundant as it is a component of water – it can even beproduced with sea water– and produces only water as its emissions when it is ...
TED演讲者:Vaitea Cowan | 瓦伊塔·考恩演讲标题:How green hydrogen could end the fossil fuel era | 绿色氢能将如何结束化石燃料时代内容概要:As climate change accelerates, finding clean alternatives to fossil fuels is more urgent than ever. Social entrepreneur Vaitea Cowan believes green hydrogen is ...
When it comes to power, hydrogen is one of the most energy dense fuels. One kilogram of hydrogen gas generates the same amount of energy as almost three kilograms of gasoline, making the chemical element a highly efficient fuel source. With water and heat as its only by products, hyd...
"It's also a clean, high-energy-content molecule that can be used in fuel cells or to store energy generated by variable power sources like solar and wind. But most of the hydrogen produced today is made with fossil fuels, adding to the level of CO2 in the atmosphere. We need a cost...

This membrane separates the anode and the cathode sides in the fuel cell system. Hydrogen is diffused on the anode side of the fuel cells, producing protons that travel through the membrane to the cathode.The electrons produced by the process are fed into an external circuit, thus creating an...
These fuel cells can be used in a broad range of applications, from powering cars and other vehicles to entire city blocks. Compared to conventional gasoline vehicles, hydrogen fuel cell vehicles can even reduce the amount of carbon dioxide being produced. If the hydrogen is produced by ...
How does hydrogen work in a car then? From its tank, the hydrogen is passed through an anode in a fuel-cell. The anode has a catalyst – usually platinum – which forces the hydrogen to split into protons and electrons. The protons get sucked across a ‘proton exchange membrane’ (PEM...
Electrification, automation and various hybrid and alternative fuel solutions are already attracting a lot of attention. However, one possibility that has been overshadowed in comparison is hydrogen fuel cell technology.
How Fuel Cells Work If you want to be technical about it, a fuel cell is an electrochemical energy conversion device. Discovered in the 1800s, a fuel cell converts the chemicals hydrogen and oxygen into water, and in the process it produces electricity. ...
