Transitioning to hydrogen: Assessing the engineering risks

Existing gas boilers in the home will need to be replaced but this can be facilitated by future sales of "hydrogen-ready" gas boilers, which can be readily converted to hydrogen. Many industrial applications should be able to convert from gas to hydrogen, although others may require blending with biomethane, for example.

H₂ydroGEM, the hydrogen boiler by Giacomini | Giacomini S.p.A.

How it works. The first hydrogen-powered domestic boiler in the world is based on a catalytic burner fueled by hydrogen gas. Within the reaction channel, a self-priming catalyst agent activates the oxidation process, with no need for electricity. Low-concentrated hydrogen combines with the oxygen in the surrounding air; this reaction produces thermal energy, or in other words heat.

Heating systems: it's time to talk about hydrogen

A cleaner heating system. The main reason hydrogen is being considered as an alternative fuel is its green credentials. When burned, hydrogen produces no CO 2 emissions, creating just water vapour and heat. Hydrogen also contains a large amount of energy, making it relatively efficient, as in 1kg of hydrogen, there is the same amount of energy as you would find in 2.8kg of gasoline.
