Expert Answer:
Yes, a body can have energy without possessing momentum.
A body may have potential energy and still can be at rest. This means it would have zero momentum and still it could possess energy.
E.g. A brick placed on the top of a building has a PE = mgh, but has got no momentum because it is not moving.
