Paris to New York in 1.5 hours: The hydrogen jet looking to usher in hypersonic air travel
Designs for a new hydrogen-powered jet could begin a new era of hypersonic flight that would cut journey times around the globe by air to a few hours.
The last aircraft to manage the feat was the Concorde, the supersonic result of Anglo-French engineering.
In its heyday, it crossed the Atlantic in record time in around 3.5 hours, flying at a speed of over 2,100 km/h.
But a Swiss start-up is looking to cut the current journey time from Paris to New York down from 8 hours to just an hour and a half – with its hypersonic, hydrogen-powered passenger jet.
While other companies are dabbling again with supersonic flight, Destinus aims to build the first commercial hydrogen-powered aircraft that can travel at five times the speed of sound and at altitudes of more than 33 km (over 100,000 ft).
The company has been testing its prototype aircraft for the past couple of years, announcing successful test flights of its second prototype – Eiger – at the end of 2022.
“The prototypes look different from the final product because the final product has very advanced propulsion technology,” Bart Van Hove, Destinus’ head of advanced studies, said during this year’s Paris Air Show at Le Bourget.
“It has different types of engines, turbo jets, and ramjet, all hydrogen-powered and all hydrogen-cooled. So that goes with a particular vehicle configuration as shape, as you see in our vision, of a plane that grabs a huge amount of air and there is a central duct and that splits into various engine ducts.
“This is not the case on the prototype. It’s more of a classical configuration because we go step by step”.
Spanish government investment
In April, the company received a boast in investment, announcing its participation in a programme run by Spain’s Ministry of Science, part of the Spanish government’s plans to develop hydrogen-powered supersonic flights.
The agency overseeing the ministry’s programme, the Centro para el Desarrollo Tecnológico e Industrial, selected the project as a strategic initiative under its Plan de Tecnologías Aeronáuticas (PTA).
With an overall current investment of €12 million, the project involves companies and technology centres as well as Spanish universities.
“We are delighted to have been awarded these grants, especially because they are a clear sign that Destinus is aligned with the strategic lines of Spain and Europe to advance hydrogen flight,” Davide Bonetti, VP Business Development and Products for Destinus, said at the time.
“For deep tech companies like us, access to these EU recovery funds is essential to carry out advanced research and accelerate the innovation needed to be competitive on a global scale. With these grants, hydrogen-based solutions for aeronautical mobility will be one step closer to becoming a reality”.
Hydrogen power is the subject of a lot of research and development, with proponents pointing to its green credentials, the main byproducts of hydrogen combustion being heat and water.
“We’re trying to do the ultimate thing, which is flying people safely with hydrogen, no emissions, hypersonically. That’s all over the world in four hours. Supersonically, that’s just impossible,” Van Hove said.
The amount of heat generated presents a design challenge, though.
Researchers at RMIT University in Melbourne recently developed 3D printed catalysts which they say can power hypersonic flight and act as a cooling agent to combat the extreme heat generated when aircraft fly five times the speed of sound, which is around 6,100 kilometres per hour (km/h).
At those speeds, future commercial airlines would be able to fly between Paris and New York in around 90 minutes.
Frankfurt to Sydney in 4 hours and 15 minutes
It also opens the opportunity to shorten travel around the global.
Flying across the world from Europe to a destination such as Australia currently takes around 20 hours in a regular passenger jet.
Destinus claims its technology will make a flight from Frankfurt to Sydney last just 4 hours 15 minutes as opposed to 20 hours, while a flight from Frankfurt to Shanghai would take 2 hours 45 minutes, eight hours shorter than that journey currently takes.
Destinus partnered with Spanish engine manufacturer ITP Aero in June 2022 to develop a hydrogen engine test facility.
The grant from the Spanish government will fund the construction of a test facility near Madrid where the air-breathing hydrogen engines will be put through their paces.
A second grant project of €15 million will fund research into aspects of liquid hydrogen-powered propulsion.
The project is part of Spain’s push to be at the forefront of developing and producing hydrogen-based mobility in a number of sectors.

Brits could soon enjoy shorter passport control queues at EU airports. Here’s why
British holidaymakers will soon be able to use e-gates at more EU airports, the UK government has announced.
It comes as part of negotiations between the UK government and the European Union to finalise a ‘post-Brexit reset deal’.
It means British passport holders will no longer have to wait at manned desks and will instead be allowed to use fast-track e-gates usually reserved for EU or European Economic Area citizens.
EU Relations Minister Nick Thomas-Symonds said this would give British travellers “more time to spend on holiday or work trips […] doing what you want, not being stuck in queues.”
The UK government said the move would end “the dreaded queues at border control.”
UK travellers have to join ‘other nations’ queue at EU airports
Following Brexit, UK citizens forfeited their privileged status when travelling to EU countries.
They now fall into the ‘visa-exempt third-country nationals’ category – the same classification as travellers from dozens of countries, including Australia, Canada, New Zealand and Singapore.
This has meant British travellers must join the ‘other nations’ queue at border control rather than using the expedited EU lanes.
The requirement to check that British travellers meet entry conditions is a significant obstacle to allowing them to use the fast-track lanes.
EU border control has to verify that UK travellers are not in breach of the 90-day stay limit in 180 days and that they have the means to return to their country of origin, i.e. a flight ticket out of the EU.
Frontier officials must also stamp the passenger’s passport.
This change often translates to extended waiting times, especially at busy European airports like Amsterdam Schiphol, Milan Malpensa, and Paris Charles de Gaulle.
Waits exceeding an hour have become commonplace, especially when arriving shortly after large international flights.
These delays affect not only entry into EU countries but also departure, as British travellers must undergo exit checks that sometimes result in missed flights due to lengthy queues.
UK travellers will be able to use e-gates at many European airports
Under the new deal, British travellers will be able to take advantage of the faster e-gate passport checks at many EU airports.
No details have yet been released on when this will be introduced and where, although the BBC reported that British Prime Minister Keir Starmer “has called on all EU members to co-operate without delay.”
Some EU airports will likely allow UK travellers to use existing e-gates reserved for EU citizens, while others may install dedicated ‘third-country national’ e-gates.
The latter are already in place across Italy, including Venice Marco Polo and Rome Fiumicino, as well as at Amsterdam Schiphol and Lisbon.
With this system, once the traveller passes through the gate, there is a brief check by border officials who will also stamp passports.
Brits will use e-gates in all airports after introduction of EES
In addition, the UK government underlined that there will be “no legal barriers to e-gate use for British Nationals travelling to and from European Union Member States after the introduction of the European Union Entry/Exit System [EES].”
The EES is scheduled to come into force in October this year. The system will register non-EU visitors who don’t need a visa digitally, removing the need for physical stamps.
New pet passports will make it easier for Brits to bring pets into EU
The UK government also announced that new pet passports will be introduced as part of the deal.
This means UK cats and dogs will be able to travel “more easily” from the UK into the EU by “eliminating the need for animal health certificates for every trip.”

Three killed in lightning strike at Cambodia’s Angkor Wat UNESCO temple complex
Three people have been killed and several others injured after they were struck by lightning during a visit to Cambodia’s famous Angkor Wat temple complex.
They group had been seeking shelter around the main temple of the UNESCO site when the lightning strike happened late on Friday afternoon.
Video posted on social media showed two ambulances arriving in the aftermath and onlookers and site officials carrying some of the injured people and helping others out on foot.
Other images showed multiple people being treated in hospital.
The day after the incident, Cambodia’s Minister of Tourism Hout Hak issued a statement telling people to take down online posts about the incident, saying the spreading of “negative information” could harm the country’s tourism sector.
Authorities have released no information about the strike, but an official on Monday, speaking on condition of anonymity due to the sensitivity of the issue, confirmed to the Associated Press that the three people killed were all Cambodian nationals.
The Cambodian Red Cross also posted an update saying it had delivered care packages to the families of two of the victims, a 34-year-old man and a 52-year-old woman.
The Red Cross refused to comment further by phone.
A spokesman for the Angkor Wat site did not respond to requests for comment, nor did a regional health official.
Angkor Wat is Cambodia’s best-known tourist attraction, attracting some 2.5 million visitors annually and is featured prominently on the country’s flag.
UNESCO calls the site, which sprawls across some 400 square kilometres and contains the ruins of Khmer Empire capitals from the 9th to the 15th centuries, one of the most important archaeological sites in Southeast Asia.
Cambodia has been actively developing the area to attract more visitors, including opening a new $1.1 billion (€890 million) Chinese-funded airport in nearby Siem Reap.
Its move to relocate some 10,000 families squatting in the Angkor Wat area to a new settlement has drawn widespread criticism from human rights groups and UNESCO itself has also expressed concern.
Cambodian authorities have said the families are being voluntarily relocated, but Amnesty International and other groups have questioned how voluntary those relocations have been.

‘Leave them where they belong’: Bruges implores tourists to stop stealing cobblestones
Tourists have been caught smuggling all kinds of stolen souvenirs home from holidays, from artefacts picked up in Pompeii to sand from Italy’s famous pink beach on the island of Sardinia.
The Belgian city of Bruges is the latest victim of keepsake crime, but the item visitors have taken a fancy to is unexpected.
The city council has reported the theft of dozens of cobblestones from the city centre, and suspects tourists are the culprits.
Tourists suspected of pilfering Bruges’ cobblestones
Bruges’ cobblestones are increasingly being pilfered from well-known spots in the UNESCO-designated historic centre, public property councillor Franky Demon reported this week.
“At iconic locations such as Minnewater, Vismarkt, Markt and Gruuthusemuseum, it is estimated that 50 to 70 pieces of cobblestone disappear every month. And that number could be even higher,” Demon told press.
“The phenomenon increases significantly, especially during busy tourist periods such as spring and summer,” he added.
For this reason, authorities suspect visitors are pocketing the stone as souvenirs.
‘Leave that cobblestone where it belongs’
As well as damaging a valuable part of the city’s heritage, the stolen stones have created safety issues.
The gaps from removed stones present trip hazards for pedestrians – and are costly to repair.
“It’s unfortunate that our employees constantly have to go out to fix potholes and loose stones. This causes a lot of additional work and costs: about 200 euros per square metre of reconstruction,” explained Demon.
The councillor urged visitors to respect the historical environment of Bruges.
“We simply ask for respect. Anyone walking through Bruges crosses centuries of history. Leave that cobblestone where it belongs,” he said.
Bruges’ cobblestones are apparently not the only sought-after street souvenir.
Along the famous Paris-Roubaix cycling route, tourists are known to pilfer parts of the pavement.
While Rome’s iconic ‘sampietrini’ – cobblestones made of solidified lava – have also disappeared into suitcases over the years.
