The EVALGAS project offers clients in the gas sector better efficiency, noticeable energy savings and greater safety in homes and in industry


The strong competition that has emerged in the gas sector as a consequence of market liberalisation is driving companies’ search for factors that distinguish them from each other and give them a competitive advantage.

For that reason, the main objective of the EVALGAS project is to improve the quality of service by offering clients the possibility of greater efficiency and energy savings, as well as increasing safety in residential and commercial environments.

EVALGAS, “Development of novel techniques of multiparametric analysis for the evaluation of gas mixtures in residential-commercial environments”, aims to implement a series of novel multiparametric techniques. These techniques are based on micro-nanotechnology that enables the quality of natural gas and the quality of the environment to be evaluated in both residential and commercial sectors.

Two evaluation platforms have been created. The first is an indoor air quality platform that evaluates methane and carbon monoxide concentrations in environments where natural gas combustion takes place. If concentration levels are outside the norm, alarms warn the user and supplier.

The second platform evaluates the quality of natural gas by measuring calorific values and methane concentration. This makes it possible to bill by thermal units and not only by the amount of gas used.

The recent advances in the micro and nanofabrication of materials has made it possible to develop micro and nanosensors, which, when compared to the conventional devices used to evaluate gas quality, are an attractive and technologically viable alternative.

Among the main the advantages associated with nanotechnology is that devices are very small, respond quickly, consume little energy and are inexpensive to manufacture in large quantities. These features make it possible, both in economic and technological terms, for the sensors to be placed at sites where gas is consumed and measure in situ the parameters that indicate its quality.

All these parameters are then transmitted via the communications platform to the telemonitoring and management platform. Among the many benefits of this system are the possibility of implementing smart billing and setting up alarm and warning protocols.
