Efficiency matters. But electricity price matters too.

At 10 cents per kWh, producing a kilogram of hydrogen using 50 kWh costs $5 in electricity alone. At just 2 cents per kWh, that falls to $1.

At these lower electricity prices, the financial benefit of squeezing out a few extra percentage points of efficiency becomes much smaller.

Pherrum focuses on the bigger picture: affordable equipment, flexible operation and strong efficiency, enabling hydrogen production that can take advantage of low-cost renewable electricity.

Because the goal isn't simply to make the most efficient electrolyser.

It's to make the most affordable green hydrogen.
