Disclosed is an energy hydrogen water dissolving device that passes a clean water source through a pressurized pump. A part of the water is sent to a hydrogen production equipment and decomposed into hydrogen and oxygen, and the other part of the water is driven to an energy hydrogen water dissolving and storage tank. The oxygen formed by the hydrogen production equipment is discharged to the outside or returned to the clean water source, and the hydrogen formed by the hydrogen production equipment is connected and sent to an input end of the pressurized pump, pressurized and mixed uniformly by the pressurized pump and outputted to the clean water, so that the water liquid entering into the energy hydrogen water dissolving and storage tank becomes high dissolution hydrogen water. The energy hydrogen water dissolving and storage tank contains an energy mineral, a hydrogen molecule mineral and a terminal filter, and the water liquid discharged from the energy hydrogen water dissolving and storage tank is formed into healthy drinking water with tiny water molecules, weak alkaline, high negative potential and high dissolution hydrogen molecules
