Using Hydrogen To Clear The Air And Save The Internal Combustion Engine

To save the Earth and make it a better place for his grandson when he's ready to drive, former GM engineer Mike Copeland has found a way to use hydrogen in old cars.

in its vision, hydrogen would be produced on site at airports using renewable energy before being processed and transported out to the plane. but what about the cost of all this? at the moment, liquid hydrogen is significantly more expensive than conventional jet fuel, but backers of hydrogen planes believe it will eventually become cheaper than traditional flight. zeroavia isn't the only company racing to reimagine air travel, though. aerospace giants like airbus and boeing are also developing hydrogen planes. but there are still questions over how sustainable they'll actually be. we're going to be using some fairly exotic materials that are very energy intensive to arrive at. what energy are you using to build the fuel cell? what materials are you using? how much energy are we sinking into this technology to get something out? zeroavia has the backing of the uk government and big investors and has over

2,000 pre—orders from airlines. so there seems to be significant belief in hydrogen despite all of the challenges. but what i really want to know is... are we going to be able to jet off to spain anytime soon in a hydrogen plane? history shows that you need to start small and grow big. and that growth would take a while. but if this could be scaled to the largest of planes, then the difference to emissions would be jumbo. you know, it sounds like, if they can get it right, hydrogen planes could be a massive deal. yeah. it's as much about the infrastructure, though. they've got a lot to do. right, 0k, noted. 0k, we're going from the air to the sea now. you might not think of the world's oceans as a great source of green energy, but when you think about it, the tides move an enormous amount of water around the globe every single day, and we are discovering new ways to harness this tidal power.

Space Shuttle Columbia The Final Flight

people came to me as a flight director or as manager every day. in this case, bob page knocked on my door, came in my office, and said... -"we've got a problem. this is the largest strike of the vehicle that we have ever seen." -he's a little bit of a high-energy guy, so it wasn't unusual, i didn't think. but he had a little video clip that he showed me. it's really hard to tell if anything bad had happened. i mean, this is insulating foam. it's lightweight. -so the orange, um, is the external tank which is covered in foam on the outside. -it's carrying cryogenically cold liquid oxygen and hydrogen, and it's going to sit out on the launch pad in the sunshine in florida. you don't want that to start boiling off, so over the outside of the tank there is this spray-on insulating foam.

system that will allow to have a lot of power, but minimal weight to be integrated on an aircraft is really a challenge. and that probably means completely redesigning the plane. everything will be shrunk. some parts of the engine, of the fuel cell, will be sitting inside of the nacelle, and also the storage tank, which is, uh, going to be probably the largest, uh, you know, piece of equipment they will actually bring outside, 0k? right. so either on the side of the fuselage, or we will hang it on the wing. making everything fit isn't the only challenge, though. you need to have the maintenance and repair organisation. the whole process needs to be certified. we need to provide the hydrogen infrastructure to the, uh, to the aircraft. zeroavia has a plan for that. in its vision, hydrogen would be produced on site at airports using renewable energy before being processed and transported out to the plane.

some harmful emissions. then there's electric. but although batteries are getting far more efficient, the size that you'd need to power a passengerjet would be way too heavy. and there's one potential solution that's getting people really excited — hydrogen. hydrogen fuel cells combine hydrogen and oxygen to create a flow of electrons around a circuit to power a motor. and as we all know, hydrogen plus oxygen equals h20. the problem is... we can't do much about the fundamental properties of hydrogen. volumetrically, we need to compress it to get sort of in the ballpark of not quite a third of the efficiency of fuels that we use. that means that we need often very large, very heavy tanks, because they need very thick walls to deal with the incredibly high pressures we need them at. what you end up with is an aeroplane that can't have any passengers in.

up with new fuels. let's take a look at some of the options. there are biofuels, which are made out of things like plants or vegetable oils, but they still produce some harmful emissions. then there's electric. but although batteries are getting far more efficient, the size that you'd need to power a passengerjet would be way too heavy. and there's one potential solution that's getting people really excited — hydrogen. hydrogen fuel cells combine hydrogen and oxygen to create a flow of electrons around a circuit to power a motor. and as we all know, hydrogen plus oxygen equals h20. the problem is... we can't do much about the fundamental properties of hydrogen. volumetrically, we need to compress it to get sort of in the ballpark of not quite a third of the efficiency of fuels that we use. that means that we need often very large, very heavy tanks, because they need very thick walls to deal with the incredibly high
