High-Pressure Hydrogen Production Technology to Eliminate Costly Compression Stages

energyTestedTRL 5

Imagine a water pump that doesn't just move water, but pushes it out with incredible force so you don't need a second machine to compress it later. This project does that for hydrogen gas, creating it at very high pressure and heat right from the start. It's like baking a cake that comes out of the oven already frosted and packaged, saving time and energy.

The business problem

What needed solving

Traditional alkaline electrolyzers produce hydrogen at low pressures, requiring expensive and energy-consuming mechanical compressors to reach the pressures needed for storage and transport.

The solution

What was built

A high-pressure alkaline electrolysis system including advanced separators, membranes, and Raney Ni-based catalysts, culminating in a 50-kW prototype.

Who can put this to work

Green Chemicals
enterprise
Target: Green methanol synthesis plant

If you are a chemical producer dealing with high energy costs for feedstock preparation — this project developed an electrolyzer that produces hydrogen at 80 bar. This removes the need for expensive downstream mechanical compression, reducing the levelized cost of hydrogen.

Energy Infrastructure
enterprise
Target: Gas grid operator

If you are a utility company dealing with the difficulty of injecting hydrogen into existing gas pipelines — this project developed a system producing hydrogen at 80 to 100 bar. This allows for direct grid injection without adding costly and energy-hungry compression equipment.

Renewable Energy
mid-size
Target: Offshore wind farm developer

If you are an energy developer dealing with the challenge of transporting hydrogen from sea to shore — this project developed a high-pressure stack. Producing hydrogen at 80 bar directly at the source optimizes electricity use and simplifies transport logistics.

Frequently asked

Quick answers

How does this affect the cost of hydrogen?

What is the industrial scale of the demonstration?

The project is developing a 50-kW prototype electrolyzer capable of operating at 80 bar and 120°C.

Who owns the intellectual property or licensing?

Based on available project data, the consortium includes industrial partners like AREX, AGFA, VECO, and SYENSQO, but specific licensing terms are not disclosed.

How much energy efficiency is gained?

The project aims to enhance energy efficiency by approximately 2-4% (LHV).

What is the timeline for the results?

The project period runs from March 1, 2023, to August 31, 2027.

Consortium

Who built it

The consortium is heavily industry-driven with an 80% industry ratio, comprising 8 industrial partners and 2 research centers across 7 countries. The presence of benchmark companies like AREX, AGFA, VECO, and SYENSQO indicates a strong focus on commercial viability and industrial scaling rather than pure academic research.
