The European Commission's goal in tackling ongoing climate change is clear: decarbonisation. The July 2021 "Fit for 55" plan aims to reduce CO2 emissions by 55% by 2030 and achieve climate neutrality by 2050 by increasing the use of renewable energy and improving energy efficiency.
Industry is one of the major sectors involved in energy reforms aimed at reducing climate change emissions, and there is a strong call for action. The challenge was to find a technically and economically sustainable balance between the technical solutions identified in the laboratory and the existing infrastructure.
In recent years, hydrogen (H2) has increasingly emerged as a viable alternative for the energy transition and has actually been included in the European Commission's strategy. As noted in COM (2020) 301 of 08.07.2020 "A Hydrogen Strategy for a Climate-Neutral Europe", it shows how this chemical element can be a solution for decarbonisation and reduction of CO2 emissions. Hydrogen, which is defined as "green" and obtained from renewable energy processes, is actually an ideal candidate for this role.
Focused on innovations in residential and industrial combustion, Riello has been researching this fuel for more than 10 years, either purely or as a mixture with methane. The first applications of hydrogen can be traced back to city gas in the 1960s, a gas mixture containing more than 50% hydrogen, mainly distributed in the centers of several large cities such as London and Singapore.
The Riello Research and Combustion Center of VR Anghiri has studied this technology and improved it for the use of hydrogen, either pure or in blends, in the latest range of burners.
The theoretical research was confirmed by the first tests carried out at the research center in 2010. Hydrogen has very different physical and chemical properties than methane. It has a lower calorific value and density, but a significantly higher flame temperature (up to 2000°C!). Modifications to combustion heads designed for use with hydrogen must therefore include higher fuel flow and materials capable of withstanding higher temperatures to ensure the same robustness and power as the corresponding natural gas burners.
Pure green hydrogen as an energy carrier reduces CO and CO2 emissions to zero by mainly releasing water vapor as a combustion product.
Hydrogen fuel is not yet fully regulated by European legislation, but Riello has designed, tested and certified two ranges of burners up to 1 MW for use in Europe in 2022 according to DIN EN 676:2021-09 and DVGW CERT ZP 3502 The market offers up to 20% hydrogen, and tested forced draft burners are capable of operating on up to 100% hydrogen.
Riello is aiming for European certification with mix ratios up to 20% covering both ranges for forced draft and premix burners. Specifically, the RS and RX series of burners represent Riello's range of hydrogen combustion products. Through fluid dynamics studies and careful design of the combustion head, they help to comply with the strictest NOx and CO emission limits.
These burners offer high performance over a wide range of power outputs and are equipped with the latest technology for excellent power control and combustion quality in all phases of work.
They are derived from standard products with the same reliability and robustness while incorporating the necessary solutions and upgrades to make them ideal for hydrogen combustion; they also comply with the European EMC, Low Voltage and Machinery Directives.
Riello has accumulated more than ten years of data on the combustion of hybrid hydrogen fuels and pure hydrogen fuels. Application engineers can suggest solutions for applications using non-certified blends or using 100% hydrogen.
