The Phi Suea House in Chiang Mai, Thailand: Solar-Powered and Hydrogen Energy Storage

The Phi Suea House Chang Mai ThailandThe Phi Suea House development in Chiang Mai, Thailand consists of 4 family homes and other support buildings fully powered by photovoltaic panels and an innovative hydrogen energy storage system.

During the day, excess solar power is used to run electrolysers and produce hydrogen, which can be transformed back in to electricity through a fuel cell at night.

The first phase of the development is completed and the energy system has entered the testing phase with the first three buildings. The system will be 100% operational when construction is completed at the end of 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. The Phi Suea House development energy system differs in how it is employed at day and night. A diagram of the Phi Suea House development energy system. There are four family homes in the Phi Suea House development, as well as several other purpose-built buildings. According to project developer CNX Construction, the homes will be the first in the world to run on solar-powered hydrogen storage.

To achieve this, there will eventually be 114 kW of photovoltaic panels generating around 441 kWh of electricity a day, a partial excess of which will be stored in two 2,000-Ah lead-acid battery banks. Electrolyzers will then convert additional excess power into hydrogen gas by applying an electrical current to water. The hydrogen will then be stored until it is needed, typically at night, at which point it will be changed back into electricity via fuel cells.

When fully up and running, the system will reportedly be able to produce hydrogen at a maximum rate of 2,000 l (440 gal) every hour and will be able to store up to 90,000 l (19,800 gal). The daily demand for electricity will be in the region of 200 kWh and the fuel cells will be able to produce 120 kWh at full storage, easily covering the estimated 80 kWh that will be required overnight.

To ensure the efficiency of the houses, they will have solar hot water panels installed, meaning that no electricity will be be required for heating water. In addition, the houses will have double glazing, thick walls, natural ventilation, efficient fans to reduce air conditioning use, plus large windows and lower-power LED lamps to minimize the energy required for lighting.

Building high quality homes means finding the right materials, partners and workers for the job. We’ve assembled a team of experts in their field who are always seeking to challenge themselves with different ideas and technologies. Our employees are perpetually evolving from attending new trainings and classes. CNX Construction is the only company in Northern Thailand with a KNX certification, the worldwide standard for home automation.
