Bluemethane: Innovating clean energy from liquids

Capturing methane from waste streams and turning it into green energy – cutting emissions, creating value, and powering a cleaner future.

How it all began

We’re on a mission to recover one billion tonnes of greenhouse gas from liquid waste streams by 2050.

Why? Well, although the threat has been invisible, stemming methane leaks from wastewater and other water sources could be one of the most powerful ways to quickly slow climate change.

Globally, 51 billion tonnes of greenhouse gases are released into the atmosphere from human activity every year. Three billion tonnes are from methane escaping from water. Our team is working to capture this methane before it heads up to the atmosphere.

What we do

We’re unlocking the value of wasted methane from liquid streams. By capturing this potent greenhouse gas,
Bluemethane creates a clean energy resource but also delivers substantial improvements in operational efficiency and a vital reduction in methane emissions.

Where it all began

Bluemethane began with a surprising discovery. Nestor, an engineer with years of experience in hydropower, read that reservoirs emit a billion tonnes of greenhouse gases, something he’d never heard of before. Inspired during a warm Dutch winter, he developed a low-energy method to capture methane from water to prevent a bit more global warming.

Meanwhile in England, Louise, a marketing strategist passionate about sustainability, was looking to make a real impact. During a virtual climate tech fellowship in 2021, they were paired up and instantly connected over Nestor’s big idea. By May 2021, they’d both left their jobs to co-found Bluemethane…without having yet met in person. They finally met in London that September.

Starting a company remotely might seem crazy – but waiting for someone else to fix the climate crisis seems even crazier.
