Val Miftakhov makes a compelling case for hydrogen aviation

Everybody but the oil companies wants electric aviation to take off as quickly as possible, if you’ll pardon the pun. The aviation industry is a huge polluter, and electric aircraft will not only be cleaner, but significantly cheaper in terms of energy and maintenance. The custodia per samsung a8 problem custodia cover samsung note 10 is batteries, whose terrible energy density is simply not up to any practical aeronautical purpose at this stage, and there’s no guarantee that the vast amounts of research going on in the battery sector will change that any time soon.

Many companies are now starting to view hydrogen as the answer. Batteries are still a much better solution for 99 percent of car usage, but hydrogen’s outstanding energy density makes it a much better proposition for anything that flies, and you don’t need to build a massive distribution network to commence medium range hydrogen flights. Indeed, if you can get electricity to an airport, you can generate your hydrogen right there on site.

We caught up with Val custodia samsung galaxy tab s2 amazon Miftakhov, founder and CEO of ZeroAvia, a company that’s betting heavy on hydrogen in the aviation space. Where some are focused on the short range eVTOL air taxi market, ZeroAvia is getting started on mid range regional flights by developing and retro fitting fuel cell powertrains to small, 10 20 seat passenger planes. The company says it can reduce costs by as much as 50 percent on this kind of operation.

If you’re in doubt that hydrogen aviation is going to be a thing, Miftakhov makes an excellent case for it cover samsung s3 flip in the lightly edited transcript below. He’s not competing with batteries, he’s competing with jet fuel, and the numbers look like they might really stack up in the very near future. We’ll let Miftakhov take it from here in his own words.

New Atlas: Hi Val, where are you speaking to us from

Miftakhov: I’m in Cranfield, UK, we have a location here at a small airport belonging to Cranfield University, one of the best samsung galaxy custodia aerospace schools in Europe. Cranfield Aerospace Solutions is one of the partners for us and we’re cover samsung 7 tablet doing some of our testing here.

Can you sum up how ZeroAvia came to be and where you’re at right now

My background is in physics, management consulting, Google, Uber, then I started my previous company in the electric vehicle space, eMotorWerks we became the largest vehicle to grid integration company out there. That company was acquired two years ago and that’s when I started ZeroAvia.

I’m a pilot myself, a private pilot flying airplanes and helicopters, so it’s a personal custodia samsung galaxy tab 3 10.1 passion for me. Having spent a number of years in the zero emissions custodia cover samsung a70 transport space, it made a lot of sense to focus on aviation, look at what sustainability in aviation might look like and how we can bring it to the world.

We thought early on about how we can address the large existing segments of aviation. There are a lot of companies focusing on urban air mobility, flying cars and so forth. We thought that these are all great projects, interesting technologically, but they wouldn’t do anything to our emissions footprint in the existing aviation segment. If you’re flying from Melbourne to Sydney, that’s not going to be helped by any of the flying car companies today.

That was the motivation: how we can start bringing those segments into best cover samsung s10e the zero emissions world. Once you do the math, and start trying to understand what technologies you can use to get there, pretty quickly you’ll zoom in on hydrogen fuel cell based powertrains. There’s nothing else that really works that well.

Batteries are too heavy, biofuels cannot scale, hybrids with turbine engines don’t really make sense you’re increasing the complexity of the powertrain for relatively limited gain on longer trips.

What remains are hydrogen based propulsion methods. One is hydrogen electric, and that’s what we’re doing with fuel cells. Another is synthetic fuel, which uses cover samsung s6 edge con disegni the same turbines as you have in aircraft today, but produces fuel from hydrogen into synthetic liquid jet fuel. The latter is more expensive, requires more energy and still has all the disadvantages of liquid fuel burning: particulate emissions, nitrogen oxides, turbine engine maintenance and so forth.

We think that hydrogen electric is going piccolo principe cover samsung to samsung galaxy s10e hoesje be the dominant force over time in clean aviation, and that’s why we’re doing it.

So where are you at with it

We started at the end of 2017. In 2018, we put the initial team together and started ground testing of our powertrain. It’s a California company, with a UK subsidiary. In February 2019, in the US, we put the first version of our powertrain in an aircraft, a six seat, two ton Piper Malibu M330.

We got initial FAA certification on that prototype, and got it cover samsung a3 2017 ciambelle up in the air in the spring of last year. Started flight testing, learned a lot. Earlier this year, we built the second prototype here in the UK. The UK operation is supported partially by government grants here from the Aerospace Technology Institute.

Now I’m here in Cranfield kicking off flight testing for the second prototype.

Do you see any specific barriers to certification for hydrogen electric powertrains

Well, the main barrier really is the lack of standards for these new powertrains. If you build a new piston engine or a new turbine engine, you have a testing book. When you design and test the engine before the certification, you’ll know what to expect.

In the case of new engine types, and that includes battery electric and any others that aren’t traditional engines, and definitely hydrogen electric, you don’t have a book. So first and foremost, you need to work with the regulators to write the book. That’s what we’re doing now already with the FAA in the US and the CAA here in the UK, so that in 12 18 months, we can show up with a system that we think can be certified, and there will be a book against which it amazon custodia samsung galaxy s2 can be tested.

So this is the main barrier. From a technology and physics perspective, there are no physical barriers.

I was talking to the HyPoint turbo air cooled fuel cell guys a couple of weeks ago. There seems to be a perception out there that a hydrogen powerplant is inherently dangerous in an aviation context. Can you speak to that

Yeah, the HyPoint guys are great. We’re cover samsung j3 2016 con panda partnering with them on a couple of things. But this is a frequently asked question for sure. A custodia cover huawei mate 10 lite lot of times people bring up the Hindenburg from 80 years ago. But technology has moved on quite a bit.

Today, on the ground, hydrogen fuel cell vehicles are a real thing. Since about five years ago, Toyota started pushing migliori cover samsung galaxy s6 hydrogen cars onto the market to regular consumers, with fueling and everything. So there’s now maybe 15,000 hydrogen vehicles in circulation on the ground worldwide, plus maybe 30 35,000 material handling equipment. Not in the air, but the technology, the storage and utilization of hydrogen in those vehicles is similar to what you have in the air. Fuel cell tech with compressed hydrogen storage that you produce electricity out of.

In our conversations with the FAA and CAA, hydrogen is something they find to be more conceptually similar to the other chemical fuels, compared to batteries. In the hydrogen based powertrain, you have fuel storage where fuel is kept separate from the oxidizer the air at all times, except for a very small amount that flows in the fuel cell. That’s versus batteries; what makes people worry is that the fuel and oxidizer are all in one package, impossible to separate if something goes wrong. So you have these runaway effects in large scale, high energy density batteries that are very hard to contain. Once a battery fire starts, for example, it’s very difficult to stop.

Then cover samsung piquadro you look at things like ignition temperature of hydrogen much higher than jet fuel. It’s practically impossible to pool hydrogen in one place, or maintain a concentration in the open air. It’s custodia libro samsung s3 neo very lightweight, it escapes very quickly. Jet fuel and custodia samsung a 2017 aviation gasoline have vapors that are really heavy, and they concentrate around the leaked fuel. Those can ignite much more easily.

So there are some fundamentals for hydrogen that are actually custodia cover huawei y6 2019 better than jet fuel from a safety perspective. Of course, we’ll need to do the right amount of testing and so forth. But we’re pretty optimistic…
