Felix saw Scorch gazing at an aeroplane for a long time. He asked, “Scorch, haven’t you seen an aeroplane before? Remember when you accidentally burnt an aeroplane seat with your fireballs? I had to use my wand to save everyone.”
“Ohh I remember very well. If not for you, the entire plane would have caught fire,” replied Scorch, “Speaking of this aeroplane, this is an electric aircraft made by H2FLY.
H2FLY is an aircraft developer from Stuttgart, Germany. Its aim is to make air travel more sustainable by using hydrogen as fuel to fly aircraft.
Usually, aircraft use jet fuel or kerosene as a fuel to fly. But it emits lots of harmful gases into the atmosphere. So, H2FLY used liquid hydrogen to power the aircraft and reduce emissions.”
Felix scratched his head, asking, “What is liquid hydrogen?”
“Hydrogen is a colourless gas. It is also the lightest gas in the world. Liquid hydrogen is hydrogen in a liquid or water form,” replied Scorch, “Liquid hydrogen is mainly used as a rocket fuel.
Four flights from Slovenia, a country in Europe, flew with liquid hydrogen. One flight among them lasted for over three hours. It increased the flight time, reduced the harmful gases, and reduced the overall tank weight of the HY4 aircraft.”
Before Felix could talk, Scorch said, “Before you ask, HY4 is a hydrogen-fuel cell-powered aircraft. It first flew in 2016 in Germany. H2FLY introduced the hydrogen-electric fuel system. Here, liquid hydrogen powers an electric motor, which then powers the propeller (fan). After adding this method, it travelled an extra 750 kilometres, thus reaching 1,500 kilometres.”
“This is a major breakthrough in the aircraft industry. We should soon go on a ride in that aircraft!” exclaimed Felix.
