Hydrogen can be produced when there is a surplus of variable renewable electricity, then stored and used to generate heat or to re-generate electricity. [136] Hydrogen created through electrolysis using renewable energy is commonly referred to as "green hydrogen". [137] It can be further transformed into synthetic fuels such as ammonia and ...
Liquid hydrogen (H 2 (l)) is the liquid state of the element hydrogen. Hydrogen is found naturally in the molecular H 2 form. [4] To exist as a liquid, H 2 must be cooled below its critical point of 33 K. However, for it to be in a fully liquid state at atmospheric pressure, H 2 needs to be cooled to 20.28 K (−252.87 °C; −423.17 °F). [5]
Using hydrogen's lower heating value, the maximum fuel cell efficiency would be 94.5%. [33] The efficiency of a hydrogen combustion engine can be similar to that of a traditional combustion engine. If well optimized, slightly higher efficiencies can be achieved. The comparison with a hydrogen fuel cell is interesting.
BSc meteorologist Janice Davila tells Bored Panda that one of the most unknown facts from her field of expertise is that weather radars are slightly tilted upward in a half-degree (1/2°) angle.

The hydrogen-powered Tu-155 prototype made its first flight on 15 April 1988.. A hydrogen-powered aircraft is an aeroplane that uses hydrogen fuel as a power source. Hydrogen can either be burned in a jet engine or another kind of internal combustion engine, or can be used to power a fuel cell to generate electricity to power an electric propulsor.
