Hydrogen is a environmentally friend energy.One way people get hydrogen is through electrolysis. Electrolysis is when you put electricity through water .
The diagram on the board shows electrical currents being put into water making hydrogen and oxygen bubbles to form. which then can be used at electricity.
The diagram drawn on the board is the process of how gasification works. first starting with the gasification, the cc stands for crushed coal and the so standing for solids out. so the coal gets crushed the solids go out while the gases stay. first going through the process of removing the left over particulates, the removing the sulfide then the carbon dioxide and water leaving chemical fuels. Next heading over to the WGS shift getting the hydrogen and finally to fuel cells which use it for electricity.
Another way people get hydrogen is through gasification. That is when coal is turned in to gases.

Finally high temperature water splitting is when you split water into hydrogen and oxygen using high temperatures.
High temperature water splitting is don by heating up water to a extremely high temperature making the water boil and making bubbles for that contain hydrogen and oxygen.
