Riello Start

A LOOK INTO THE FUTURE START is born now, thinking of tomorrow. The new condensing range is, in fact, designed to operate with blends of natural gas and hydrogen - up to a maximum of 20% - a contribution towards the decarbonisation process started by the European Union. HYDROGEN USE CYCLE Hydrogen is a safe and clean gas that, blended with natural gas up to a maximum ratio of 20 to 80 percent, makes it possible to generate heat and domestic hot water, with lower CO 2 emissions than other fuels*. RENEWABLE ENERGIES ELECTROLYSIS HYDROGEN COMBUSTION HEATING AND DOMESTIC HOT WATER PRODUCTION * Data from E. A. Polman (2003) “Reduction of CO 2 emissions by adding hydrogen to natural gas”, IEA Greenhouse Gas R&D program, report number PH4/24. Variation of Wobbe index and CO 2 reduction as a function of hydrogen content. The hydrogen is presumed to be made by large-scale steam reforming and that CO 2 is captured with a recovery rate of 86,7% of CO 2 .
