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 ...
Energy giant AGL this weekunveiled plansto produce hydrogen power at its Loy Yang A coal station. But how do we transform coal, which is often thought of as simply made of carbon, into hydrogen – a completely different element? In fact,coalis not just made of carbon. It also contains o...
About Us: Here at HFN we explore answers to questions like what is a fuel cell, what is green hydrogen and what is the use of hydrogen. On this page we answer how hydrogen fuel cell is made but make sure to sign up for our free ebook that explains about what a hydrogen community is...
How Do Hydrogen Fuel Cells Work? Hydrogen fuel cells are just one of many alternative energy sources that offer a comprehensive list of benefits. A hydrogen fuel cell is comparable to a battery in that it can produce electricity without relying on combustion or emissions. But unlike batteries, ...
Here we take a look at the process of a fuel cell in a car… Part 2–What is PEM Fuel Cells and how do they work? One of the more popular types of fuel cells are proton exchange membrane (PEM) fuel cells. These fuel cells make use of a proton-conducting polymer membrane that acts...
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...
Discusses a research by engineers at the Laboratory for Energy and the Environment at Massachusetts Institute of Technology which refuted the notion that fuel-cell vehicles are non-polluting technology. Level of pollution from the ...
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'...
In recent years,hydrogenfuel cells have proven immensely scalable and have come to be used in growing numbers of planes, trains and automobiles (if you’d like more information on this, take a look at our articles on each of these developments). For many, however, these fuel cells...
Do you believe we will see hydrogen internal combustion jet engines powering planes in the future, or will hydrogen-electric and fuel-cells be more prevalent? Leave a comment below and join the conversation.
