Our products

We have the solution

Developing the electrolyser technologies that make green hydrogen universal.

The lowest cost of green hydrogen

Polymer Electrolyte Membrane (PEM) electrolysis is the lowest cost, most efficient technology on the market for the 1-10MW range, which is our initial target market.

Our innovative, proprietary solutions blend performance and durability in systems to deliver market-leading operational and capital efficiencies.

Our technology is driving down the cost of green hydrogen

The benefits of Polymer Electrolyte Membrane electrolysis:

  • Utilisation time

    Wide window of operation leads to higher utilisation

  • Electricity cost

    Decreasing costs of renewable energy

  • System cost

    Low cost design built for scale manufacture

  • Asset lifetime

    High durability ensures minimal asset maintenance required

  • System throughput

    High production rates drive lower CAPEX

  • System performance

    High efficiency means low OPEX

The future of universal green hydrogen

From proof of concept work in 2019, to testing a 10 kW stack in 2021, we are now commissioning our 250 kW demonstrator system.

While our long term goal is the 100 MW energy storage market, our first product is a PEM electrolyser. Our second product will be optimised for 100+ MW market, and we are currently in R&D exploring alternative chemistries.

The Oort Energy Electrolyser

Our electrolyser efficiency gains allow us to operate with the same throughput as competitors with lower OPEX.

Not only that, we can produce smaller electrolysers that operate at the same efficiency levels as competitors, but with lower CAPEX.

The benefits of Oort Energy’s Electrolyser:

  • Novel low cost stack design

  • Novel MEA that allows unparalleled performance

  • A bipolar plate coating that increases lifetime
