Boris Adamovich Rybakov, Chief Technologist of ANO «Hydrogen Technological Solutions», has talked about the next stage of testing a 30 kW gas piston unit. During the tests, various types of fuel were burned: gasoline, methane, a mixture of hydrogen and methane, as well as pure hydrogen. Apart from estimation of power and fuel consumption, special attention was paid to measurements of emissions of nitrogen oxides and carbon.

Carbon monoxide (CO) is a product of incomplete combustion of carbon and is usually formed due to lack of oxygen and low temperature. Nitrogen oxides, on the contrary, are formed due to excess of oxygen at high temperatures. These substances pose a serious threat to the environment and human health.

The trial results demonstrated significant differences between the types of fuel. So, when running on gasoline, the CO level reached 20,000 ppm, and the content of nitrogen oxides made up 600 ppm. The transition to methane led to a decrease in these indicators to 5,800 ppm and 178 ppm, respectively. However, the most impressive results were obtained in consequence of the pure hydrogen usage: the CO level was only 2,300 ppm, meanwhile nitrogen oxides were completely absent.

With an increase in the load up to 9 kW, the CO and nitrogen oxides’ figures remained significantly lower in installations running on hydrogen than in methane-run installations. Further tests confirmed this trend even with an increase in power up to 15 kW.

The tests also included the use of mixtures of hydrogen and methane with different proportions, which made it possible to receive additional data on the effect of fuel composition on emissions of harmful substances. Despite the ongoing adjustment of engine parameters, the overall picture remains positive: the transition to hydrogen fuel considerably reduces harmful emissions.

Thus, the conducted tests have clearly demonstrated the advantages of using hydrogen as an environmentally friendly energy source. The reached results open up new prospects for the development of hydrogen technologies.
