The trickiest part is to regulate the flow of liquid hydrogen to ensure efficient consumption over the longest range possible, Dinelli said.Another challenge: the liquid hydrogen must be maintained at minus 253 degrees Celsius (minus 423 Fahrenheit), or nearly absolute zero. Construction of a leak-proof tank is essential. Liquid hydrogen is highly flammable, so any seepage could have devastating results.

Aviation’s share of carbon emissions is relatively small, but growing faster than in any other industry because development of electric-powered planes trails far behind electric cars and trucks on the ground.Batteries are heavy in EVs on roads today, and keeping down battery weight in planes will be crucial for electric-powered flight.

“We have not had a ‘Tesla moment’ in aviation yet,” said Nikhil Sachdeva, an expert in how the aviation sector can transition to more climate-friendly technologies at consulting firm Roland Berger. “Hydrogen has the potential to be that for aviation, which is why it’s worth doing this right.”

Using super-cold liquid hydrogen is “extraordinarily difficult, and we can barely do it for a few minutes right now. And here we’re talking about doing it safely for hours,” Sachdeva said.“The great distance between the defendant’s power plants and the plaintiff’s residence in Peru alone was not sufficient reason to declare the lawsuit unfounded,” the court said in a statement.

Experts said the case has setin the fight to hold major polluters accountable for

that are currently underway and opens the door for future litigation,” Sebastien Duyck, an attorney with the Center for International Environmental Law, told The Associated Press.Roda Verheyen, Lliuya’s attorney, called the court’s decision “a milestone and will give a tailwind to climate lawsuits against fossil fuel companies, and thus to the move away from fossil fuels worldwide” even though her client lost.
