Smarter Hydrogen Production. Lower Costs. Automatically.
GreenFlex Hydrogen Solution
The Challenge
Hydrogen production is electricity-intensive — and power is often the single largest operating cost. While wholesale pass-through tariffs and renewables offer access to cheaper energy, most operators aren’t equipped with the tools to respond fast enough to capture the maximum benefit.
If you're on a wholesale pass-through tariff, electricity prices can shift every five minutes — and without automated control, that volatility turns into risk instead of opportunity. Manual scheduling simply can’t keep up.
The Solution: GreenFlex Hydrogen
GreenFlex Hydrogen is an intelligent control system that helps you take full advantage of a wholesale tariff. It aligns hydrogen production with low-cost electricity and scheduled offtake — ensuring you run when power is cheapest, and pause when it’s not.
It combines real-time electricity price forecasting, renewable energy predictions, and a digital twin of your site to optimise operations every five minutes.
How GreenFlex Hydrogen Works
GreenFlex Hydrogen connects to your electrolyser, energy systems, storage, and logistics schedule — creating a smart control layer that plans and adjusts operations in real time. It uses electricity price forecasts, solar generation predictions, and your tube trailer pickup schedule to build an optimal daily production plan. Then, every five minutes, it updates that plan based on the latest market conditions, renewable forecasts and site data.
Crucially, GreenFlex doesn’t just chase low prices — it also accounts for the long-term health of your electrolyser. It factors in degradation and wear from cycling, ramping, and extended runtime, so every decision balances cost savings with asset life.
This enables precise control over when to:
-
Run at full power to meet scheduled hydrogen demand at the lowest cost
-
Switch to standby when short-term price spikes make production inefficient
-
Shut down during prolonged high-price periods to avoid uneconomical operation
By continuously adjusting to real-world conditions — and protecting your equipment — GreenFlex ensures hydrogen is available when it’s needed, at the lowest cost, and with longer-lasting assets.

Cost Saving Potential
Electricity is the biggest operating cost in hydrogen production. GreenFlex Hydrogen helps you reduce it — by as much as 25% — through smarter, real-time control of when and how you use power. This chart shows how GreenFlex compares to traditional high-voltage tariffs. By shifting electrolyser operations to times when electricity is cheaper, exporting solar power to the grid when prices are high, and avoiding prolonged high-price periods, GreenFlex delivers substantial savings.
Many hydrogen producers default to standard retail electricity tariffs, assuming they provide cost stability. But with rising renewable penetration and increasing price volatility, wholesale electricity markets now offer significant cost-saving opportunities for hydrogen producers.
Electrolysers are uniquely positioned to take advantage of shifting electricity prices. Unlike fixed industrial loads, hydrogen production can be scheduled when power is cheapest, avoiding peak costs and capitalising on ultra-low or even negative price periods. However, without a system that can forecast market pricing and optimise production timing, these savings go unrealised.
GreenFlex Hydrogen bridges this gap. Our system forecasts electricity prices, predicts renewable availability, and dynamically adjusts hydrogen production to align with the lowest-cost energy periods. This ensures you’re always running at the most cost-effective times, reducing electricity expenses while maintaining reliable hydrogen output.
Electrolysers that can adapt to market signals will lead the future of hydrogen production. If your energy strategy isn’t using market forecasting to lower costs, you’re missing a major opportunity.
