How might a technique to remove A and B antigens from red blood cells be used to increase the supply of donated blood?

That would be extremely useful if it can be developed. There are four types of blood: AB, A, B, and O. They are classifed by the antigens that they have. Type O blood has no antigens but it does have anti-A and anti-B antibodies, so it can only accept type O blood (although since it has no antigens, it can give blood to anyone). Type A blood has A antigens and anti-B antibodies so it can't accept any blood with B antigens in it (such as type B or AB). Type B blood has anti-A antibodies and can't accept A or AB blood. Type AB has A antigens and B antigens so it can't donate to any other blood besides AB (although it can receive any type of blood). If everyone was type O blood, and didn't have any antigens, then every type of blood would be able to receive it because the antibodies wouldn't have any antigens to react with so it would be accepted by anyone.

Why blood type A can receive blood from type AB?
A can donate to A because they are the same type. To donate from an A to an AB requires a little more effort. Every person's blood, except for AB blood has antigens which mark blood with "additional letters" as foreign, prompting their destruction. For example, type A blood will have anti-B antigens, type B blood will have anti-A antigens, and type O blood will have both anti-As and anti-Bs. However, AB blood has neither because it has both A and B. However, if blood from an A was put directly into an AB person, the anti-B antigens would begin to attack the AB's native blood, which would cause a number of problems. Therefore, the A blood must first be cleaned of antigens before being able to be donated. A cannot donate to O or B because those people have anti-A antigens in their bloodstream and would just keep making it (even if you found a way to remove all of their current anti-A antigens). This would lead to the body attacking the new blood as opposed to using it.

How does your body protect itself from antigens?
I don't know exactly how detailed you want me to go with this, but a simple answer is that it produces antibodies against those antigens. I guess an easy way to put it is that our white blood cells have the ability to fight off foreign materials (antigens), which is what our fighter T cells do. After we are exposed to those antigens, our body also makes "memory" cells (B cells), so that if we are exposed to the same antigen later in life, our body will "remember" how it fought them off the first time and respond quickly to remove them.
