With 4.5 billion passenger trips taken each year and more than 16 million planes taking off annually in the U.S. alone, aircraft are responsible for 2.5% of global CO2 emissions, and the problem is growing. But there could be a solution that rivals the power of fossil fuels without the negatives - hydrogen. Aircraft giant, Airbus, is exploring the technology, as well as new startups, ZeroAvia and Universal Hydrogen. CNBC explores hydrogen planes and whether they could fix aviation’s emissions problem.

The flight companies won't stop the supply unless the demand disappears. so it is the job of the public to renounce air travel to bring change, not the job of the companies to reduce emissions. It is us the people doing international travel all the time that are the root of the problem. Demand creates supply

Former USAF flight surgeon and undergrad chemistry major here. Hydrogen has a very low energy density per volume and must be stored under immense pressure and/or low temperatures in order to have adequate energy to power anything other than very short flights. That requires very heavy, very expensive alloys. The very tiny molecule hydrogen literally seeps into metals and other materials causing “hydrogen embrittlement” and accelerating material fatigue. Extremely low temperatures make all materials less malleable and more prone to sudden, catastrophic fracture. Metals are bad, but plastics and other polymers can be even worse at low temperatures. Maintaining the necessary low temperatures adds even more weight and energy expenditure not directed to flight. Air pressure decreases with altitude magnifying the material stresses even more. The repeated ascents and descents under such immense pressure changes induce accelerated material fatigue. Temperatures also drop precipitously at altitude. H2 fuel cells and their platinum or iridium catalysts do very poorly at low temperatures. Direct combustion is more plausible, but H2 is incredibly explosive if a leak develops. Shut-off valves work well with liquid jet fuel, but much less well with gaseous H2 under immense pressure. All of the fuel lines and valves must be able to withstand all of the radical changes in pressure and temperature as well as the bulk H2 storage tanks. All of this adds immensely to weight which in turn stresses the non-fuel portions of the airframe and reduces flight efficiencies. We perform non-destructive stress damage analysis on current planes. This would needed to be performed even more sedulously on hydrogen planes. More delays and costs. Hydrogen-powered ships-yes; hydrogen-powered planes-I respectfully have my reservations. I hope they prove me wrong, but I heard none of these issues addressed to any significant degree. I am willing to be persuaded. Best wishes.

This would help viewers appreciate what it actually takes to achieve and sustain 13,000 psi or minus 425F, and the challenges created by such pressures and temperatures during transporting and storage as compared to traditional liquid fuels.

While H2 is energy dense by mass, by volume it leaves much to be desired. H2 also needs to be either cryogenically frozen or highly pressurized in storage which drags on its round trip efficiency. H2 could still play a big role in green ammonia production, which has greater energy density by volume without the previously mentioned problems of h2. The holy grail in my view would be developing a scalable and cheap direct ammonia fuel cell (vs having to crack the ammonia back to H2, which again, drags on efficiency).

I'm more worried what they left out. 1. Hydrogen production or the production of black Hydrogen which results in more pollution since it is the only cheap way to produce hydrogen. 2. hydrogen cells use rare metals like iridium and pt which has become really really expensive and only a few countries dominate the market. 3. Storage, due to the hydrogen and the way it bonds with metals all pressurized tanks have to be specially coated which makes them really expensive and heavy. So it seems that hydrogen in aviation has a lot of issue to solve.

I don't think that we need to worry about the round-trip efficiency of H2 as much as we do. The extraordinary energy density by weight is the most important part of it, enabling its use as a green fuel in aviation and long-haul trucking. An electrolysis-based production process can easily be run on the excess power generated by solar and wind plants that might otherwise be wasted, making the round-trip efficiency much less important.

Aviation is where hydrogen makes the most sense to start a hydrogen economy. Next would be replacing natural gas with hydrogen. Then hydrogen for trains, busses, trucks, and finally passenger cars. Hydrogen is a great way of storing and transmitting energy. There are however a number of technical, safety, and economic hurdles to overcome. Hydrogen can be produced from water and electricity. Renewable, nuclear, or even fossil fuels. Thus hydrogen could ultimately be not only the cleanest fuel, but also the cheapest fuel.

CNBC does top-notch documentaries, interesting and well researched. Ammonia is really the key here...too bad there was no mention of it (though this doc was focused on H2)...NH3 is a better H2 carrier than liquid hydrogen....about twice as much and its in liquid form can be held at a much lower pressure about 10 bar (while H2 gas is at 700 bar)...that's the real future imo. Ofc NH3 is a toxic substance, so we'd need to handle it better than we do gasoline (as it can cause blindness), but for decarbonizing, it's the pinnacle for an alternate energy source.

Define gravitational forces. How can we reverse it or cancel it? Can we build a machine that could make it possible? 2. Is that possible to find a material to isolate or deflect gravitational forces 3. Can we convert gravitational forces into a power source? I'm quite sure that somebody could take the challange & make it possible, like Wright Brothers. If we can convert sunlight into electricity by using solar panels why can't we achieve creating weightlessness by harnessing gravitational forces?

In the nearer term though, I suspect some mix of biofuels and carbon neutral synthetic efuels will be what initially decarbonizes air travel before hydrogen tech is able to become a superior technology. To get the ball rolling I suggest legislating that private jets be LEGALLY REQUIRED to use carbon neutral fuels, be they biofuels, efuels, green hydrogen, direct electricity, or something else. This will help stimulate the market and development to make these technologies become more available at larger scale by having those who CAN pay the premium, do so in the early days.

As a child in the fifth grade in the 1960s I learned from a science textbook how to make hydrogen and oxygen from water using electrolysis. Since then I have always wondered why not just connect a solar cell or windmill generator to a water electrolysis device and use wind or solar energy to make hydrogen. I guess there are technical reasons why this won't work. This video mentions that storing hydrogen as a gas takes a lot of room and storing as a liquid requires super cooling equipment. Hopefully scientists will come up with an answer to these issues and soon.

Major improvements in converting water to hydrogen and fuel cell technology will have to be solved before it will be cheaper than today. Although we could argue the overall cost of burning fossil fuels is extremely expensive since it also causes major pollution and climate change. But hydrogen is not a solved problem and it is very expensive to make, to store, and to use.

the problem with Hydrogen is the cost in energy and other resources in producing pure hydrogen, storing it, distributing it, so all the advantages of hydrogen quickly evaporate when you add up all the cost. We need research on reducing the cost of all of this before we can make good use of hydrogen.

The main issue is the production of hydrogen. The conventional method of hydrogen production involving the use of methane and fossil fuels ends up producing CO2 as a byproduct. The alternative method of using electrolysis of water is very expensive and a net energy sinking process because the amount to energy required to split water is higher than the amount of energy released in burning hydrogen if the efficiency of the entire process is taken into account.

It's true, hydrogen is an inconvenient energy carrier and requires high safety efforts. Nevertheless, the comparison of hydrogen powered planes with airships with hydrogen as a liftig gas is nonsense!

There is no "extra electricity". Any power diverted to manufacture "green hydrogen" means less power to offset power generation by burning fuels. As converting energy into a chemical fuel to be later converted back into energy elsewhere (especially hydrogen) represents major loss of efficiency it only serves to increase net CO2 emissions over if power had been directly used by the energy grid. Also, before all this money gets dumped into hydrogen as an energy carrier I'd like to see estimates of how much hydrogen leaks into the environment during its production, transportation, storage, and conversion. Leaked hydrogen quickly rises into the high atmosphere and depletes the Ozone layer and creates the greenhouse gas water vapor in the high and normally dry layers of the atmosphere.

The problem is that hydrogen fuel cells is an interm technology. By the time it could reach maturity it will be outpaced by competing technologies like solar paired with battery packs. This is a completly different use case but there's a reason the military already has uav drones that are solar powered and not hydrogen. They can essentially fly continuously. If hydrogen was to successfully disrupt the aviation and other industries it would of had to be implemented 15 years ago where it would of drastically outcompeted any other avaliable technology and been able to gain footing and develop the needed infostructure.

You don't really need hydrogen to reach 0 CO2 emission goal. You can just produce a conventional aviation fuel from plant sources. For example corn is used to produce fuel in Brazil. Whatever CO2 produced by such fuels will be re-absorbed by the plants to produce oxygen. So overall the total net emission of CO2 would be 0. If there is not enough land for planting, they can use sea and using algae, the same goal is achieved. This is much less costly and can re-use the existing airplanes and technology.

A plane with a hydrogen combustion turbine producing jet thrust and driving either a prop or fan? Maybe, eventually, certainly before oil derived aviation fuel is exhausted in 60 years time. But in the meantime an e-fuel made by combining renewable energy produced hydrogen with atmospheric captured CO2 kit the best option was as it adds no new CO2 to the atmosphere, it just recycles it. Producing enough for large commercial airliners and distributing would be a major challenge and so it is not a solution for land transport as well. Possibly heavy shipping though.
