Autothermal reforming uses oxygen and carbon dioxide (CO2) or steam to react with methane to form hydrogen. The downside of these two methods is that they produce carbon as a by-product, socarbon capture and storage(CCS) is essential to trap and store this carbon. ...
As a unique energy source with almost zero harmful emissions, hydrogen is central to the energy sector. The demand for hydrogen as an energy source is expected to increase by more than seven times by 2040. However, hydrogen is not naturally available in a usable form for energy storage techno...

Hydrogen can also be produced through electrolysis. This is when electricity is used to split water (H2O) into hydrogen (H2) and oxygen (O2). If the electricity used in this process is generated with renewable sources, the production process is free of emissions. This type of hy...
In electrolysis, water splits at the anode to form oxygen, hydrogen ions, and electrons. An electrolyte material allows hydrogen ions through, but forces electrons to flow separately to the cathode, where the two recombine to form hydrogen gas for use as fuel. Credit: Argonne National Laboratory...

What ion does hydrogen form? What group does hydrogen belong to? A positively charged hydrogen ion is made up of what? What is the charge of a proton? How many ions does hydrogen have? What is the charge of an electron? What charge does oxygen have?
Hydrogen is one of the most basic building blocks of the world around us. It easily combines with other elements and molecules (to form, for example, water), and with those combinations, countless things can be made — including energy. Using hydrogen in the process of storing energy is app...
What is renewable hydrogen? Renewable hydrogen is hydrogen derived from water. It’s created using a process called electrolysis, wherein electricity from renewable sources is used to split the hydrogen molecules from the oxygen molecules in water. Because the electricity used here comes from renewabl...
What is the biggest challenge for the hydrogen fuel cars?A. They cost more than we expected.B. There isn’t enough fuel for them.C. There is lack of refueling stations.D. They are difficult to control on the road.答案：C 分析：解析:细节理解题。从第二段第二句可知,对于氢气汽车来讲,最...
