Groundbreaking technology can power your home for days using half the water needed to flush a toilet

[Dec 19, 2022: JD Shavit, The Brighter Side of News]

Emission-free hydrogen could, one day, entirely replace fossil fuels - and a start up in Germany believes it has the key ingredient to make it accessible to all.

Born in a climate-change affected South Pacific Island, Vaitea Cowan believes deeply in green hydrogen technology. She co-founded Enapter more than three years ago.

"I wanted to replace all the diesel generators in New Caledonia and all the remote areas that didn't need to rely on dirty diesel, " she says.

"But then realising the potential for green hydrogen to replace fossil fuels, I wanted to be part of this change."

Green solutions will only be adopted if they are the most economically attractive. And that's our mission at an after to make green hydrogen cost-competitive with fossil fuels.

With headquarters in Germany, the company has deployed its ion exchange membrane electrolysers in over 100 projects across 33 countries. The technology turns renewable electricity into emission-free hydrogen gas.

Developed more quickly and cheaply than once thought possible, the AEM electrolyser already fuels cars and planes, powers industry and heats homes.

Enapter's hydrogen generators have recently won Prince William’s Earthshot Prize in the 'Fix Our Climate' category.

Much of the planet's hydrogen is locked up in water. So-called 'green' hydrogen is an emission-free way of extracting it. This extraction relies on renewable energy, which is used to power electrolysis. Electrolysis is the chemical process needed to separate the hydrogen and oxygen atoms in the water.

Extracting hydrogen this way has been facing criticism, because of its low efficiency and high cost. Enapter says, however, that their AEM Electrolyser solves these problems and provides a quick and easy way to produce green energy, even at home.

Enapter says its electrolyser uses about 2.4 litres of water to generate enough hydrogen for a couple's home for several days.

However, the exact number of days depends on the power storage capacity. This amount of water is equal to half of the water used for flushing a toilet once (5 litres), and eight times less than the water consumption of a dishwasher (20 litres).

Enapter recently joined seven other leading European cleantech companies to announce the formation of a new Cleantech Scale-up Coalition, with the goal of helping Europe become climate neutral, energy autonomous and industrially competitive.

The coalition is supported by Bill Gates, founder of Breakthrough Energy and Kadri Simson, European Commissioner for Energy, both in attendance at the event.

The coalition members of the Cleantech Scale-up Coalition are companies scaling and industrialising technologies to help Europe become climate neutral, energy autonomous and industrially competitive. Their products and services range from decarbonising industry and energy with renewable hydrogen to producing scalable low-carbon cement; from electrifying transport to recycling materials and batteries.

By 2050, Enapter’s hopes to produce 10% of the world’s hydrogen.
