If you missed our first Hydrogen Energy Summit, catch up all the content here.


The Phi Suea House is a sustainable residence project fully powered by photovoltaic panels harvesting the sun’s energy.

Its innovative hydrogen energy system is a central solution for community solar power and storage. We believe it is the answer to energy needs of the future, and is the solution that stores energy in the most effective and ecological way. We have combined strategies to minimize our impact on the land we live on. We designed and built a water collection system to save and reuse as much of the rain and irrigation water as possible. We directly harness heat provided by the sun to heat water with specifically engineered panels. We also integrated home automation for its potential in energy saving and carbon footprint reduction.

By utilizing windflow and growing a permaculture garden, we aim for a holistic approach to sustainable living.

The Phi Suea House project is a modular concept. It is ideally suited for residential or other developments in remote locations; or where complete independence from the grid is desired.

Energy building

The energy building has two functions: to store energy and distribute power. It has the largest array of solar panels and is divided in three rooms: the control room, hydrogen room and battery room.

Excess power from the photovoltaics is used to power electrolyzers that split water into its composite gases. The hydrogen gas is then stored in tanks. The energy storage is a hybrid battery-hydrogen system. The bulk of the nightly demand is covered by the fuel cells using hydrogen, while the batteries help cover short peaks in demand.

Phi Suea House is a 100% self-sustaining 24-hour solar powered multi-house residence.

The first of its kind, the Phi Suea House is the materialization of our dream to achieve cleaner and more sustainable energy systems The most up-to-date sustainable technologies from around the world effectively power this residential development.

Our energy system is designed to store solar power in the most effective and ecological way. The hybrid hydrogen-battery system maximizes the advantages of both the hydrogen storage system and the batteries.

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 is not shining we will use the stored hydrogen gas from tanks to generate electricity by using fuel cells.

Hydrogen is a clean energy source that is created from water and electricity, via a process called water electrolysis. We use a unique technology called the Anion Exchange Membrane (AEM) Electrolyzer, that splits water into Oxygen and Hydrogen. There are other technologies available, the AEM is only one of them.

We have combined various strategies to minimize the impact on the land we live on.
We strive towards a holistic approach to sustainable living without compromising on standard of living.

At the Phi Suea House

Sabina Fay Braxton, known for her exuberant extrapolations of ancient hand-printed textile techniques, has been creating fabrics for renowned couturiers, interior designers, and an array of discriminating private clients for over a decade. Baroque in spirit and endowed with the adventurousness of a Mediaeval explorer, Braxton found a form of expression to convey her rich experiences and impressions. Her extraordinary use of color, and the remarkable manner in which she transforms, cloth and design, is truly her trademark. These inimitable textiles are concocted and cultivated in her ateliers in Paris and in an ancient mill in Ireland.Braxton has baptized “Gilded Gaufrage”, a technique in which the pile is embossed by heated carved blocks, encrusted with metals and stained with inks that create a patinated, iridescent and luminous effect on the cloth that orthodox printing methods cannot achieve.

Water good idea: Solar-powered home stores energy as hydrogen

December 22, 2015

Although solar panels can be used to power a home with clean energy, demand for power fluctuates during the day and excess power is often also produced. A new development in Chiang Mai, Thailand, reportedly solves these problems. It converts excess power to hydrogen and stores it for use later.

So far, the project has been a success. We are working tirelessly to face the challenges and analyze the rewards of such a system. We want to share our shortcomings and successful partnerships in order to facilitate future projects and initiatives. By sharing what we have learnt during the design and implementation of such a system we hope to inspire and instigate future sustainable developments.
