Where does the energy stored in inductor go on opening the switch?
This is a situation where the simple rules are insufficient. You simply cannot analyze that circuit any more than you can solve x+2=x+3. What happens in the real world is that the inductor creates enough emf to form a spark in the switch. This means the switch no longer acts like an ideal switch. In the real world, we call this effect "flyback.".

What happens when a switch is closed?
When the switch is closed, the current that points right-to-left for the inductor increases in the direction of the loop. As a result of Faraday's law, the inductor becomes a "smart battery" that acts to reduce the current, which means there is a voltage drop: Einductor = − LdI dt
