Revolutionary technology can power your home for days with half the water needed to flush a toilet.

Emission-free hydrogen could one day completely replace fossil fuels, and a start-up in Germany believes it has the key ingredient to make it affordable for everyone.

Born on an island in the South Pacific affected by climate change, Waitea Cowen is a deep believer in green hydrogen technology. She co-founded Enapter over three years ago.

“I wanted to replace all the diesel generators in New Caledonia and all the outlying areas that didn’t need to use dirty diesel,” she says.

“But then, realizing the potential of green hydrogen to replace fossil fuels, I wanted to be part of that change.”

Green solutions will only be taken if they are the most economically attractive. And it is our mission to make green hydrogen cost-competitive with fossil fuels.

What is green hydrogen?

Most of the planet’s hydrogen is contained in water. The so-called “green” hydrogen is an emission-free way to extract it. This production is dependent on renewable energy, which is used to power electrolysis. Electrolysis is the chemical process required to separate hydrogen and oxygen atoms in water.

The extraction of hydrogen in this way has been criticized because of its low efficiency and high cost. However, Enapter claims that their AEM Electrolyser solves these problems and provides a quick and easy way to produce green energy even at home.

However, the exact number of days depends on the capacity of the energy storage device. This amount of water is equal to half the water used for a single toilet flush (5 liters) and eight times less than a dishwasher (20 liters).

Enapter recently joined seven other leading European cleantech companies to announce a new Cleantech Scaling Up Coalition to help Europe become climate neutral, energy independent and industrially competitive.

The coalition is backed by Bill Gates, founder of Breakthrough Energy, and Kadri Simson, European Energy Commissioner, who are both present at the event.

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

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