Airships might seem like a technology from a bygone era, but a startup says their new design could become a crucial cog in the green hydrogen supply chain.

While transitioning away from fossil fuels will prove crucial in our efforts to combat climate change, it’s easier said than done for some industries. While road and rail transport are rapidly electrifying, in aviation, batteries are a long way from being able to provide the weight-to-power ratio required for aviation. And even the largest batteries are still not big enough to power a container ship on long-distance crossings.

Hydrogen is increasingly being seen as a promising alternative for these hard to decarbonize sectors. It has a higher energy density than natural gas and can either be burned in internal combustion engines or combined with oxygen in a fuel cell to create electricity.

While much of today’s hydrogen is derived from natural gas and therefore not much better than fossil fuels, in theory you can also make it by using renewable electricity to power electrolyzers that split water into hydrogen and oxygen. Producing green hydrogen economically is still a huge challenge, but there are hopes that it could help wean hard to electrify sectors off polluting fossil fuels.

But transporting hydrogen remains a sticking point: Areas that are abundant in renewable energy such as sun and wind are not always close to where the hydrogen is needed. Shipping large amounts of the gas around the world will clearly be a major logistical challenge, but a start-up called H2 Clipper has an ingenious workaround.

Archer Aviation’s electric vertical take-off and landing (eVTOL) demonstrator Maker has completed its first hover flight, marking the company’s first full and complete systems validation.  

“The past six months have been an incredible journey, from unveiling Maker to watching it take its first flight,” said Brett Adcock, Archer co-founder and co-CEO. “It’s been humbling to build a leading eVTOL company and educate the public on clean transportation alternatives.” 

Archer’s Maker demonstrator is an autonomous two-seater eVTOL vehicle that has been certified for flight testing by the United States Federal Aviation Administration (FAA). The next step is to test Maker’s capabilities of forward flying.

It started in 2017 with a simple sketch and three years later, an experimental aircraft was born. Now, Czech Republic-based manufacturer Zuri releases a video with the first hover test of its hybrid VTOL (vertical take-off and landing) flying machine. 7 photos

Zuri carried the test back in September, but it only shared the video now, boasting of achieving a true milestone in developing its aircraft.

The VTOL with a wingspan of 36 ft (11 m) took off and achieved its first hover flight at an airport near Zbraslavice. Even though it was just a short hover up to 9.8 ft (3 m) altitude, it was still a great opportunity for the team to measure several performance parameters of the motors and control systems, parameters they couldn’t obtain during the aircraft’s ground performance tests.

UK’s Heathrow airport is gearing up to operate electric vertical take-off and landing (eVTOL) vehicles. In just a few years, zero-emissions air taxis could become day-to-day reality. 

Vertical Aerospace believes it has more conditional pre-orders for its eVTOL than most companies in this industry, reaching up to 1,350 aircraft worth $5.4 billion. American Airlines, Virgin Atlantic, Avolon, Bristow Group, and Iberojet are some of its global customers. In addition, the company has now taken a significant step in the UK by teaming up with a hub airport. 

Vertical and Heathrow will begin working on the adequate framework for future eVTOL operations, from airport infrastructure and regulatory changes that need to be made to analyzing the potential impact on the surrounding communities and job opportunities. According to Vertical, some of the airlines operating at Heathrow are interested in supporting the development of eVTOL technology and bringing it to the public.

There’s an ongoing debate about sustainable aviation fuel (SAF) versus hydrogen when it comes to the subject of sustainable aviation. Some say that SAF is the best available solution right now, while others think that liquid hydrogen is the answer for long-term green aviation.

While the U.S. Government is investing millions of dollars into SAFdevelopment-related projects, and giants such as United Airlines are signing huge purchase agreements for alternatives to conventional fuel, a small startup in the Netherlands is slowly working on the world’s first manned liquid hydrogen-powered aircraft.

AeroDelft is an impressive company not just because of its very ambitious goal but also because its team consists of 50 students from various institutions, including TU Delft, Erasmus University Rotterdam, and Utrecht University, representing a total of 17 nationalities. Each of these students is bringing a unique expertise to Project Phoenix, set to become the first zero-emissions aircraft running entirely on liquid hydrogen.

The company was set up in 2018 and is currently working on both the 1:3 scale prototype and the full-scale version. The prototype (Phoenix PT) is an E-genius airplane with a wingspan of almost 20 feet (6 meters) and a maximum take-off weight of 110 lbs (50 kg). In comparison, the full-scale version (Phoenix FS) is a two-seater Sling 4 aircraft with a wingspan of almost 33 feet (10 meters) and a take-off weight of 2,000 lbs (920 kg).

Image:The solar-powered Zephyr aircraft could soon be spending up to six months in the air at a time

The aircraft could be used for internet connectivity as well as for military purposes, and Airbus has previously signed deals to provide versions of it to the UK’s Ministry of Defence.

Airbus has flown a solar-powered aircraft on two 18-day trips, and says the Zephyr could soon spend six months in the air at a time.

The skinny plane, which resembles an unmanned glider although it has two small propellers, has had two test flights in civilian airspace.

It operates in the stratosphere, higher than planes but lower than satellites, and the company hopes it could help bring internet connectivity to billions of people around the world.

ORLANDO, Fla. — Orlando is preparing for when flying cars are an option for those who want to soar over congested highways or between nearby cities. And they may arrive far sooner than 2062, as “The Jetsons” predicted.

The city has signed onto a partnership with NASA to develop strategies for welcoming electric oversized drones, which take off vertically from landing pads called vertiports. The city’s first vertiport, to be built by the German company Lillium, is planned for the Lake Nona area.

Though officials suspect the mode of transportation could take off in coming years, so far the Federal Aviation Authority hasn’t approved any such vehicles for use. But a recent study found that a piece of a projected $2.5 billion market could be in play for early adopters of the technology.

“We’ve heard from different operators that their hope is to be in operation with passengers sometime in the 2024-2025 time frame,” said Jacques Coulon, an Orlando transportation planning projects coordinator. “For us, that means they’ll want to have a vertiport in place and so we’ll need to have regulations set and full understanding of what those impacts are before then.”

Air taxis may still be pie in the sky, but there’s more than one way to move the air travel industry forward. Craft Aerospace aims to do so with a totally new vertical takeoff and landing aircraft that it believes could make city-to-city hops simpler, faster, cheaper and greener.

The aircraft — which, to be clear, is still in small-scale prototype form — uses a new VTOL technique that redirects the flow of air from its engines using flaps rather than turning them (like the well-known, infamously unstable Osprey), making for a much more robust and controllable experience.

Co-founder James Dorris believes that this fast, stable VTOL craft is the key that unlocks a new kind of local air travel, eschewing major airports for minor ones or even heliports. Anyone that’s ever had to take a flight that lasts under an hour knows that three times longer is spent in security lines, gate walks and, of course, getting to and from these necessarily distant major airports.

“We’re not talking about flying wealthy people to the mall — there are major inefficiencies in major corridors,” Dorris told TechCrunch. “The key to shortening that delay is picking people up in cities and dropping them off in cities. So for these short hops, we need to combine the advantages of fixed-wing aircraft and VTOL.”

You’ve probably heard of satellite advancements that are taking telecommunication systems and capabilities to the next level, but did you know that there’s an unmanned, solar-powered aircraft that’s about to revolutionize telecommunications services? 9 photos

High Altitude Platform Stations (HAPS) are an alternative to satellites operating in the stratosphere instead of space. HAPSMobile, a subsidiary of a Japanese corporation called SoftBank, is one of the pioneers in this rising industry and developed the Sunglider. 

This innovative aircraft is meant to carry the telecommunications payload to the required area, and the fact that it’s been backed by NASA shows the importance and potential of this new way of providing connectivity. In addition, this norm-breaking air vehicle was supposed to stay at operational altitudes for a long time without having to return to the ground for refueling.

According to Airbus, the moment of hydrogen is approaching rapidly. Guillaume Foley, chief executive officer of an airplane maker, has been talked about as a fuel for the future for years, but by the end of the decade the company will manufacture hydrogen-powered commercial airliners. He said he was ready to start.

European aerospace champions are skeptical among other industry leaders about how quickly gas can affect aviation emissions, but the 2035 will be the “ for hydrogen planes to go into service. I am more and more convinced that it is a fair and realistic perspective. 

“You don’t have to change the laws of physics to deal with hydrogen. Hydrogen has three times the energy density of kerosene — [technically it] Foley told reporters at an Airbus event on sustainability in Toulouse.

Foley’s comments show Airbus’ growing confidence that it can tackle the complex engineering and safety challenges needed to make hydrogen-powered aircraft work. However, Foley warned that government and regulatory support would be needed. 

Airbus needs to have “some degree of certainty” about the regulated environment and fuel availability by 2027/28, when the company must decide whether to invest billions of dollars in its new hydrogen airplane program. Said there is. 

“this [decarbonisation] The challenge is not just for airplanes, but for getting the right fuel, the right hydrogen, at the right time, at the right place, at the right price, which aviation cannot manage on its own, “he said. 

Foley’s remarks underscore the growing urgency of the aviation industry as it strives to reach its zero-emissions goal by 2050. Before the pandemic led to many landings of the world’s aircraft fleet, aviation accounted for about 2.4% of the world’s emissions.

The electric aircraft market has gone from zero to 60 in just a matter of months, now that one of the world’s largest airframers has entered the race. Airbus said its Helicopters division is developing an electric take off and landing (eVTOL) air taxi that could take its first flight in 2023. 

This is in stark contrast to Airbus archrival Boeing, which just last week committed only to consider alternative propulsion technologies in the near- to medium-term. 

Meanwhile, Brazil’s Gol is committing to order up to 250 Vertical Aerospace eVTOLs through lessor Avolon and in partnership with Grupo Comparte to create an urban air taxi platform for country’s most congested cities. Gol’s proposed equity partner American Airlines also has a commitment for Vertical Aerospace’s VA-X4 aircraft.
