There is a hydrogen production system that is designed to last 20 years with minimal maintenance.

With over 80% of global wastewater untreated due to financial and energy constraints, Wastewater Fuels has created a system that turns wastewater into hydrogen and electricity.

Their modular, scalable technology works for both on-grid and off-grid setups. Unlike traditional high-energy methods, Wastewater Fuels use the energy in wastewater with microbial electrolysis cells (MECs) to treat it.

Here’s how it works: Microorganisms break down organic matter in wastewater, releasing hydrogen. An electrical current then converts this into hydrogen gas—a clean energy source.

Recently, Wastewater Fuels secured a £100K grant from the TechX Clean Energy Accelerator, which highlights its promising potential.

Meeting energy demands while staying true to their sustainability labels will be a challenge for big companies in the energy sector. 

The key solution here is to keep track of what smaller companies and startups are doing, and quickly adapting to the new innovations coming to the market. 

My teammate handpicked a few startups that are doing great in this space, especially in using MEC technology to create green hydrogen, here’s the list: https://www.greyb.com/blog/microbes-hydrogen-production-startups/
