- Thailand is moving full steam towards clean energy, for carbon neutrality and net zero greenhouse gas emissions.
- Zero Hydrogen energy is another option that the world is talking about. In Thailand, it is still in low use, but it is believed that in the future, it will be used more.
- Today, let’s get to know the Butterfly House project in Chiang Mai Province, “the world’s first home” using Green Hydrogen energy, and celebrate its 10th anniversary by holding the 3rd “HYDROGEN SUMMIT”.
Get to know the Butterfly House project in Chiang Mai Province, “the world’s first home” using Green Hydrogen energy, celebrating its 10th anniversary by organizing the 3rd “HYDROGEN SUMMIT”, presenting the green energy leader stage, supporting Thailand towards carbon neutrality and net zero greenhouse gas emissions.
The world, including Thailand, is moving full steam towards clean energy for carbon neutrality and net zero greenhouse gas emissions. Hydrogen energy is another option that the world is talking about. In Thailand, it is still in low use, but it is believed that in the future, its use will increase. #SPRiNG had the opportunity to join the trip to visit Butterfly House in Chiang Mai Province.
It is the world’s first residential building project using Green Hydrogen energy, a pioneering project in sustainable housing development, and demonstrates the potential of hydrogen energy to support Thailand’s goal of achieving carbon neutrality and net zero greenhouse gas emissions.
On the occasion of its 10th anniversary, the project is organizing the Hydrogen Summit 2025 on January 16-17, 2025, to serve as a platform for leaders and stakeholders in the hydrogen industry from around the world to share experiences, exchange ideas, and present approaches to promoting the hydrogen economy both in Thailand and internationally.

For Thailand, there is a commitment to achieve a long-term goal of achieving carbon neutrality by 2050. In addition, geopolitical situations, increased occurrence of natural disasters and the urgency of responding to climate change have made it necessary to build energy resilience as many countries turn to alternative energy sources.
In order to reduce the dependence on fossil energy, the Butterfly House project has proven a viable approach at the individual, community and national level to harness hydrogen to solve environmental problems and achieve net zero greenhouse gas emissions, while also helping to build the country’s economic competitiveness.

Butterfly House is a unique project in the world, a 100% self-sufficient solar powered home using cutting-edge hydrogen electrolyzer technology to convert water into hydrogen, to produce, store and use hydrogen as energy. This innovative method allows the home to generate all its own energy without relying on the electricity grid, while maintaining zero emissions and demonstrating the potential for future housing development in Thailand.

“Butterfly House is a concrete example of how sustainable technologies can be integrated to create a truly zero carbon living environment,” said Sebastian-Justus Schmidt, owner of Butterfly House and founder of Enapter. “By using solar power and hydrogen storage, we have demonstrated a model that can significantly contribute to Thailand’s environmental goals.”

The Butterfly House is the centerpiece of the project, which was established 10 years ago, and plays a role in reducing the use of fossil fuels by using natural, non-polluting renewable energy sources. Mr. Schmidt said, “Over the past 10 years, the Butterfly House has been powered by 100% renewable energy, without relying on electricity, which proves the practicality and sustainability of the house. In addition, the changing environment has significantly reduced the use of fossil fuels such as coal, oil and natural gas, and hydrogen will become an important part of the future energy transition.
The Butterfly House project is in line with Thailand’s commitment to achieve carbon neutrality by 2050 and net zero greenhouse gas emissions by 2065. Key features of the Butterfly House that support these goals include:
•Solar-Hydrogen Hybrid Energy System: This off-grid energy system fully utilizes the power of the sun to power the house with clean energy 24 hours a day, even when there is no sunlight. This system provides a continuous and stable power supply, reducing the dependence on fossil fuels and emitting no carbon. The Butterfly House is also a real-world example of integrating modern renewable energy technologies for sustainable living, inspiring similar projects in Southeast Asia and around the world.

The Hydrogen Solar Power System at Butterfly House is an innovative energy solution designed to demonstrate sustainable off-grid living by integrating solar panels with a hydrogen energy storage system to provide year-round energy independence.
The system consists of 140 kilowatts (kWp) of solar panels, which produce electricity during the day for the home’s immediate energy needs, while excess solar power is used to produce hydrogen through a 20 kW electrolyzer that splits water into hydrogen and oxygen. The hydrogen is stored as a gas at a pressure of 35 bar. The tank can hold up to 42 kg of hydrogen, which can power the home with around 600 kilowatt-hours (kWh).

At night or during low-light conditions, stored hydrogen is converted back into electricity using an 8-kilowatt hydrogen fuel cell system. When hydrogen combines with oxygen, it becomes electricity and water, which has no impact on the environment, ensuring that clean and environmentally friendly energy is used. In addition, the Butterfly House system also has a 384-kilowatt-hour (kWh) battery. When combined, the hydrogen and battery can store energy for at least 7 days during the low-light and cloudy seasons.
- Energy-efficient design: The Butterfly House uses passive cooling techniques, including proper insulation and low-energy appliances. The open architectural design makes full use of natural light. In addition, the construction and structure of the house uses more than 98 percent sustainable materials sourced domestically, such as pressed concrete blocks and insulated double-story windows.

•Water Management System: The house’s sophisticated irrigation system captures and treats rainwater to reduce its dependence on external water sources. The water is used to grow seasonal local fruits and vegetables in the garden and rice fields. It also reduces the need for external sources of food, which often produce polluting transport emissions, promoting food security and reducing the household’s overall greenhouse gas emissions.
The Butterfly House is not only a testament to technological innovation, but also serves as an educational platform, raising awareness about sustainable living and stimulating more research and development. The continued success of the project has positioned Thailand as a leader in Southeast Asia and globally in adopting clean energy solutions and creating a sustainable future.
