The Phi Suea House by Enapter is a hydrogen house in Thailand that is a groundbreaking off-grid, solar-powered smart home that uses green hydrogen for electricity, mobility, and energy storage—demonstrating a truly circular energy future.

Introduction: Where the Future Is Already a Reality

In the quiet hills of Chiang Mai, Thailand, a house stands alone, not just architecturally but ideologically. It hums with the energy of a new era, drawing power not from wires stretching to the grid but from the sun overhead and the hydrogen stored beneath its roof.

This is the Phi Suea House. It is not a vision of the future; it is the future, built in the present. The home of Sebastian-Justus Schmidt, CEO of Enapter, the Phi Suea House, is the world's first fully hydrogen-powered, off-grid smart home. And it's not just a marvel of engineering; it's a daily, functioning example of how we can live, move, and thrive without fossil fuels.

The Vision: Beyond Grid, Beyond Carbon

Sebastian didn’t want to install solar panels. He tried to answer a question most hadn’t yet dared to ask:

Can a home be self-sufficient in both energy and transport completely off-grid, all year round, using only renewable energy stored in hydrogen?

The challenge was immense: to create a home that withstands monsoons and dry spells, one that fuels not just lights and laptops but also a car—a hydrogen-powered car with zero emissions and no compromises. And then, do it with elegance and reliability.

The Solution: Circular Living, Powered by the Sun

At the heart of the Phi Suea House is a seamless energy loop:

  • Solar panels generate electricity to meet the daily needs of the home.
  • When generation exceeds usage, modular AEM electrolyzers from Enapter convert the surplus electricity into green hydrogen.
  • Hydrogen is safely stored on-site and used later via hydrogen fuel cells, which supply electricity when the sun isn’t shining.
  • A private hydrogen refueling station on the property powers Schmidt’s Toyota Mirai, a fuel cell electric vehicle that he drives more than 25,000 kilometers annually using only the excess energy the house doesn’t need.

This is a home that not only powers itself, but it powers the freedom to move. The system is fully scalable, meaning Schmidt could add more vehicles or expand energy use without depending on the grid. The house is a living embodiment of circularity: zero emissions, full autonomy, and built-in resilience.

Proof, Not Promise

The Phi Suea House has been operating for years. Through monsoons, dry seasons, and the demands of daily life, it has remained a functioning proof of concept, not in a lab, not on a rendering board, but in the real world. It is not hypothetical. It is home.

This residence produces more hydrogen than it consumes every year, which fuels clean transportation, air conditioning, lighting, refrigeration, and every other modern necessity.

The feeling of this kind of living isn’t just satisfaction; it’s liberation. This project illustrates how energy can be harvested from sunshine, providing energy that can be used to live off the grid and travel thousands of kilometers via onsite hydrogen refueling for any hydrogen fuel cell electric vehicle. 

Scaling the Vision: From Chiang Mai to Global Logistics

The Phi Suea House's success didn’t end at its garden gate. Its impact inspired a broader vision: What if warehouses, logistics hubs, and industrial buildings could function the same way?

Enter Klean Industries, in partnership with CMA CGM, the world’s third-largest shipping company, and CEVA Logistics, the largest tire distributor globally. Drawing inspiration from Phi Suea’s elegant hydrogen loop, these organizations are working together to replicate the model at scale:

  • Solar arrays on the vast rooftops of CEVA’s tire distribution warehouses.
  • Electrolyzers convert that solar energy into hydrogen.
  • Hydrogen fuel cell infrastructure on-site.
  • Toyota's hydrogen fuel cell trucks are refueled directly at warehouses, eliminating the need for diesel fuel and reducing both Scope 1 and Scope 2 emissions, thereby redefining green logistics.

This model can fuel hundreds of trucks in markets like Australia from a single logistics hub, creating the world’s first true hydrogen-powered, circular logistics ecosystem.

What's Next: A Journey You Can Follow

The Phi Suea House is just the first chapter. What follows is the scaling of that story from a single home to a continent-wide logistics network, from personal transportation to fleet-scale freight, and from one visionary to a network of partners building the future.
