Low-cost decentralized electrical energy storage using liquid ammonia

energyPrototypeTRL 3

Imagine a giant battery that doesn't use lithium, but instead turns electricity into a liquid fuel called ammonia. This liquid can be stored in tanks for a month and moved around easily, like diesel, to be used where it's needed. It's like freezing electricity into a liquid form to save it for a rainy day.

The business problem

What needed solving

Renewable energy is intermittent and often produced far from where it is needed. Current large-scale ammonia production (Haber-Bosch) requires massive capital investment and is not suitable for small-scale, on-site energy storage.

The solution

What was built

A lab-scale turnkey system consisting of a PEM cell, AC-DC Frequency Power Generator, and a synthesis loop for liquid anhydrous ammonia.

Business applications

Who can put this to work

Chemical Manufacturing
enterprise
Target: Methionine producers

If you are a chemical producer dealing with high costs of ammonia feedstock — this project developed a PEM cell system that produces liquid anhydrous ammonia on-site. This allows you to integrate renewable energy directly into your production line, reducing reliance on external suppliers.

Renewable Energy
any
Target: Off-grid wind or solar farm operators

If you are an energy producer dealing with temporal mismatches between power generation and demand — this project developed a storage system that holds electrical energy for 1 month. It converts excess power into ammonia at 50 bar and room temperature to prevent energy waste.

Shipping
mid-size
Target: Green fuel vessel operators

If you are a shipping company dealing with spatial mismatches in fuel availability — this project developed a high energy density carrier in the form of ammonia. This enables the transport of stored electrical energy in a cost-competitive way across different geographic locations.

Frequently asked

Quick answers

How does the cost compare to existing industrial methods?

The system is designed to outperform the conventional Haber-Bosch Reactor in CAPEX by eliminating expensive heat exchangers and compressors, while maintaining similar OPEX.

What is the industrial scale of this technology?

It targets a market gap for decentralized production scales between 1 kW and 10 MW, specifically for production rates under 1000 kg/h of ammonia.

What is the IP or licensing status?

Based on available project data, specific licensing terms are not mentioned, but the project is developing a groundbreaking PEM cell concept and specific catalysts.

How is the system integrated with power sources?

The system uses a project-built AC-DC Frequency Power Generator to couple renewable energy to the PEM-cell for high energy efficiency.

What is the timeline for the project results?

The project period runs from 2023-10-01 to 2027-09-30.

Consortium

Who built it

The consortium is highly balanced for commercialization, featuring a 50% industry ratio with 4 industrial partners and 4 research/university entities. It includes a strategic mix of catalyst manufacturers (C2CAT), power-to-X specialists (ELTRONIC Fueltech), and end-users in the chemical sector (ADISSEO), ensuring the technology is developed with direct market feedback from 7 different countries.
