Where was it installed?

The Phi Suea House (Home of the Butterflies) is the world’s first solar-hydrogen multi-house which has been off-grid since 2015.

How it works?

Sunshine and rain cover all energy and water needs on the premises facilitated by Enapter electrolysers. In simple terms, the energy of the sun is transformed via solar panels into electricity. Any excess power will be converted and stored as hydrogen. When the sun doesn’t shine, the stored hydrogen gas in tanks generate electricity by using fuel cells.

What have we learned from working on this application?

It demonstrates to the world how sustainable living can be achieved.

The Phi Suea House (Home of the Butterflies) is the world’s first solar-hydrogen multi-house which has been off-grid since 2015.
Enapter electrolysers power all energy and water needs onsite, converting solar energy to electricity and storing excess power as hydrogen. During low sunlight, stored hydrogen fuels electricity generation through fuel cells.

HTL Dornbirn – Austria

At HTL Dornbirn, the innovative Green Hydrogen training and demonstration facility, featuring the Indoor HydroCab®, empowers students to gain hands-on experience with sustainable technologies, preparing them for the energy transition while fostering collaboration between education, industry, and research.

Universität Hohenheim – Germany

A pilot plant for the production of alternative fuels based on biomethane in which hydrogen is converted with carbon dioxide to methane in a methanation reactor. The hydrogen required for this is produced in an electrolyser and is to be temporarily stored in a Type IV hydrogen tank as a buffer.

BBZ Dithmarschen – Germany

The inauguration of Hy-StorE100 at BBZ Dithmarschen on March 20, 2025, marks a significant step in training future professionals in hydrogen technologies through real-world applications, with the Indoor HydroCab®—featuring an electrolyzer, fuel cell, and hydrogen storage system—playing a key role in hands-on education.

Universidade Federal do Rio de Janeiro, Brazil

This Brazilian green H2 project aims to support decarbonizing the Amazon where the use of dirty diesel predominates.
To achieve this we installed 3 Outdoor HydroCabs® V2.1 incl. Enapter Electrolyser, Enapter dryer, Enapter water storage, water purification, fuel cells, compressor system, Enapter EMS, H2 storage (including commissioning)

Honeywell: Lotte/Osnabrueck, Germany

4 Outdoor HydroCab® was installed.

Honeywell advances sustainable energy with its new hydrogen production plant, reducing costs from €150/kg to €22/kg.

The facility features a powerful electrolysis unit, photovoltaic system, and safe hydrogen storage, enabling reliable 1 MW burner operation.
