Despite hydrogen being the most abundant element in the universe, producing cheap and clean hydrogen on Earth has been a significant challenge. Fourier, a hydrogen startup, is changing the game with its innovative approach to hydrogen production. The company focuses on making modular electrolyzers that can be mass-produced and fit into small spaces, as small as two standard server racks standing side-by-side. Investors like General Catalyst and Paramark Ventures have taken notice, leading an $18.5 million Series A funding round. Other investors include Airbus Ventures, Borusan Ventures, GSBackers, MCJ Collective, and Positive Ventures. Within each hydrogen production module, Fourier employs software to manage multiple small electrolyzers called 'blades.' Inspired by Tesla's battery management system, the company aims to optimize the operation of these blades through data analysis. The software monitors the performance of each blade, adjusts output, and identifies signs of degradation. By pushing the efficiency and production problems into a data optimization issue, Fourier aims to enhance overall hydrogen production. The startup has conducted two lab-scale pilots to validate its approach. By reimagining hydrogen production through innovative modular electrolyzers and software optimization, Fourier is at the forefront of revolutionizing the clean energy sector.
