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 ...
H2, that is, hydrogen fuel, is a molecule consisting of two hydrogen atoms. It is very flammable and can be used as a fuel that doesn’t produce any greenhouse gas emissions such as carbon. This makes it highly appealing as a renewable energy source in the global effort to mitigate clima...
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...
To rapidly heat a conversion catalyst and a selective oxidation catalyst to a temperature for activation at the starting time of a hydrogen production apparatus.SOLUTION: In the hydrogen production apparatus, the external diameter of an external cylinder 3 of a conversion section 8 is configured to...
As climate change accelerates, finding clean alternatives to fossil fuels is more urgent than ever. Social entrepreneur Vaitea Cowan believes green hydrogen is the answer. Watch as she shares her team's work mass producing electrolyzers -- devices that s
Yeah, there is. So is there a way of keeping it safe in the fuel tanks, if it's not used for the spark? Absolutely. Hydrogen power is already on our roads. It's been deployed in commercial vehicles, like buses, and it's better suited to heavy-goods lorries – some might even ...

Fuel cells are a bit like a cross between an internal-combustion engine and battery power. Like an internal-combustion engine, they make power by using fuel from a tank (though the fuel is pressurized hydrogen gas rather than gasoline or diesel). But, unlike an engine, a fuel cell doesn'...
the results of which are based on the fuel that is used for the energy system. The electrolyte that is used in a fuel cell is highly dependent on the type of fuel cell it is. If hydrogen is used as a fuel, the anode acts as a catalyst that is capable of turning the fuel into el...
