Water

Since the Project uses water as the feedstock to produce net-zero H2, an environmentally sustainable supply of water at an acceptable price is essential.

Water Supply

IEPS has under contract up to 880,000 m3 of Bow River water at pre-agreed prices with a licenced water owner.

The annual water demand for Phase 1 will be approximately 25,000 m3 (20 AcFt), including the electrolyzer demand, balance of plant needs, and water loss during conveyance and storage.

At full 450 MW production rates, the total Project water consumption will increase to approximately 670,000 m3 (543 AcFt) annually).

To put the Project’s water demand into perspective at full build out, Project water demand will be less than the amount of water recommended by Alberta Agriculture to annually irrigate 640 acres of spring wheat (i.e. between 880 and 1,000 AcFt).

Water Diversion & Storage

IEPS will divert its entire annual water demand during the spring freshet on the Bow River i.e. early May to mid June when instream flows are much higher than average. This will avoid any negative effects on the downstream river ecology.

The diverted water will be stored off-stream within an existing Eastern Irrigation District (EID) owned and operated reservoir.

As the Project’s water requirements are only a small percentage of the reservoir’s firm live storage capacity, this storage strategy will ensure that H2 production can continue year-round, even during significantly drier than normal (i.e. drought) years.
