Purpose and goal
Gas plays an important role in the move towards a more sustainable energy mix. However, the liberalization of gas markets, diversification of supply, renewable biogas injections and changes to regulations have resulted in a problem with considerable fluctuations in the gas quality in the grid. On-site gas quality monitoring has, therefore, become an urgent matter in the gas industry, driven by factors of customer protection, efficient energy conversion by gas appliances, lowering of greenhouse gases emissions, and economical effectiveness.
Expected results and effects
The solution offered by GasQuaL (in cooperation with partners) is aimed to solve this problem by providing the GasQALgorithm and GasQCELL as a novel approach for cost-efficient energy flow metering. This includes the new value proposition for gas flow meters in the form of the real-time energy flow measurement and complete residential energy billing solution, enabling real-time smart metering at a considerably lower cost. Compared to existing solutions it will have a completely new level of applicability, enabling the increase of energy efficiency and security of gas consumption.
Planned approach and implementation
The background ideas of proposed technology have been tested during preliminary investigations. The most important milestone deals with the development of measurement technique for sound attenuation and speed of sound that will work in inflow conditions typical for residential gas flow meter, introduction of correction factors for pressure, temperature, and humidity of the gas medium and development of the methodology for gas quality calculation based on the measured properties.
