Hydrogen Gas Production Through Water Electrolysis Process By Detecting The TGS 821 Sensor In Realtime With DAQ On PC

Introduction

The world is facing a significant challenge in meeting the growing global energy needs while minimizing the negative impacts on the environment. The increasing concentration of greenhouse gases and other pollutants has become a pressing concern that requires urgent attention. In this context, the use of renewable energy sources has emerged as a promising solution to address this challenge. One such alternative is the production of hydrogen gas through water electrolysis, which has gained significant attention in recent years.

Hydrogen Gas Production through Water Electrolysis

Hydrogen gas can be produced through water electrolysis, a process that involves the use of electric current to break down water (H2O) into hydrogen (H2) and oxygen (O2). This process is considered a promising solution for producing clean energy, as it does not produce any greenhouse gas emissions or pollutants. The electrolysis process involves the passage of an electric current through water, which causes the water molecules to split into hydrogen and oxygen. The resulting hydrogen gas can be used as a clean energy source for various applications, including power generation, transportation, and industrial processes.

Detection of Hydrogen Gas using TGS 821 Sensor

To detect the hydrogen gas produced through the electrolysis process, the TGS 821 sensor can be used. This sensor is a type of metal oxide sensor that can detect the presence of hydrogen gas in real-time. The TGS 821 sensor operates on the principle of changes in electrical resistance, which occurs when the sensor comes into contact with hydrogen gas. The sensor can be connected to a DAQ (data acquisition) device, which allows for real-time data collection and analysis. This enables researchers to monitor the production of hydrogen gas and make adjustments to the electrolysis process as needed.

Effect of Voltage Variations on Hydrogen Gas Production

The study explores the effect of voltage variations on hydrogen gas production using a voltage of 9 V, 11 V, 13 V, 14 V, and 15 V. The results show that the maximum hydrogen concentration produced varies according to the voltage applied. For the electrolysis process using a filter, the maximum hydrogen concentration is recorded as follows: 409.34 ppm at a voltage of 9 V, 502.25 ppm at 11 V, 863.12 ppm at 13 V, 964.11 ppm at 14 V, and 737.89 ppm at 15 V. Meanwhile, in a process without filter, the maximum concentration of the detected hydrogen is 884.66 ppm at 9 V, 930.45 ppm at 11 V, 954.68 ppm at 13 V, 1003.16 ppm at 14 V, and 1004.50 ppm at 15 V.

Analysis of Results

The results of this study show that the application of zeolite-based filters shows a significant increase in hydrogen concentrations produced in lower voltage variations, which is 9 V and 11 V. This shows that filters can help in increasing the efficiency of hydrogen production, even at higher voltages. The resulting hydrogen concentration without filter is able to outperform the results with the filter. Additionally, there are fluctuations in hydrogen concentration under the effect of voltage, which illustrates that the regulation and optimization of voltage is a key factor that must be considered in the electrolysis process.

Conclusion

Hydrogen gas production through water electrolysis is one of the promising solutions to answer the challenges of global energy needs. Through this study, the use of TGS 821 sensors and the DAQ method shows promising results in monitoring and increasing the efficiency of hydrogen production. In the future, further research and technological development in this field is expected to contribute to the reduction of greenhouse gas emissions and accelerate the transition to more sustainable energy.
