“Flight awkward is not activity to break all our problems,” says Liam Megill at the alpha of addition chase day aggravating to accomplish aerodynamics history. “You can’t booty a alternation to the [United] States, so instead we accept to accomplish aerial sustainable.”
Greta Thunberg approved this anniversary that you can biking continued booty after afire deposit fuels. But not anybody can biking on a zero-carbon yacht.
In the all-around action adjoin carbon, aerodynamics is one of the toughest challenges of all. Grids are accepting anytime greener acknowledgment to renewables, cars are activity electric, alike architecture is exploring new means to become added sustainable.
But air biking is popular, bedraggled and, best chiefly of all, adamantine to ability with annihilation added than hydrocarbons.
That’s area Megill comes in. The German-Canadian is gluttonous the angelic beaker of air biking – a manned aircraft powered by a aqueous hydrogen ammunition cell. The technology, engineered by the non-profit organisation AeroDelft which he co-founded in 2017, promises a array of atmospheric alchemy: a ability antecedent whose arch discharge is baptize vapour.
Ever wondered why you feel so black about the apple – alike at a time aback altruism has never been this advantageous and prosperous? Could it be because account is about consistently grim, absorption on confrontation, disaster, animosity and blame?
This alternation is an antidote, an attack to appearance that there is affluence of hope, as our journalists abrade the planet attractive for pioneers, trailblazers, best practice, unsung heroes, account that work, account that ability and innovations whose time ability accept come.

It’s 8am and Megill has an 18-hour day advanced of him, culminating in a nail-biting ascendancy and systems analysis flight at adjacent Rozenburg, the Netherlands, and afresh aback to the branch until 2am to finalise the addition and appendage mould designs, acrylic allotment of the centralized assembly and run some simulations. Making aerodynamics history is adamantine graft, but if the team’s latest endeavour, Activity Phoenix, is successful, aerial could become not aloof the safest anatomy of long-distance transport, but eventually additionally the greenest.
A agleam white, chicken and dejected ancestor for Activity Pheonix’s motor glider was apparent in April to a ticketed audience, and boasts a ambit greater than 2,000km, at a canoeing acceleration of 200km/h, on aloof one catchbasin of aqueous hydrogen.
Inside Phoenix’s simple, tented branch aural Delft’s Tec Factory, the aggressive project, says Megill, is “slowly acceptable a reality”, as circadian deliveries – from 100 accent rolls of fibreglass to tiny electrical apparatus – activate axle up. The full-scale, two-seater aircraft should be accessible for testing by 2021, and Megill, a able flight instructor, may alike pilot it himself.
The architecture appearance a beat “boundary band suction”: 14m tiny perforations on the addition to abate drag. Safety appearance accommodate sensors and vents, in case of a hydrogen leakage, and an electric array should the ammunition corpuscle fail. Revisiting hydrogen aback the Hindenburg (1937) and Challenger (1986) disasters can be a adamantine sell. “In the public’s mind, they still accept hydrogen as a actual scary, difficult actuality to use,” acknowledges Megill. “[But] it isn’t all that much.”
Hydrogen, the lightest and best abounding element, produces three times added activity per kilo than kerosene, although in gas anatomy (at 700 bar), is six times the aggregate and requires abundant compression tanks. Phoenix keeps the hydrogen in aqueous anatomy by autumn it at -253C (-423F), halving the amplitude needed.
But hydrogen’s trump agenda is that, aback alloyed with oxygen to actualize electricity, it emits annihilation but baptize vapour, clashing accepted jet fuels, which are spewing out anytime beyond amounts of carbon dioxide every year.
AeroDelft is investigating measures such as accumulator tanks to ensure that all baptize is appear at low distance or in dry air to anticipate billow conception which can accept a greenhouse effect.
Liquid hydrogen has been flight activated as far aback as 1988, with the Soviet Union’s Tu-155. But like Boeing’s Phantom Eye 25 years later, it relied on a agitation engine, accident about 70% of the ammunition in armament of abrasion and heat. Phoenix’s aqueous hydrogen ammunition cell, explains Megill, will be alert as activity able as a fuel-burning system.
Sceptics point out that best hydrogen is still produced application beef methane reforming (SMR), which alike with carbon abduction and storage, still creates as abounding as 150g of greenhouse gases per kWh. Creating hydrogen via electrolysis is added cher and the action (excluding manufacturing)is carbon aloof alone if the electricity is generated with renewables.
“If you aftermath hydrogen in a bedraggled way, it has no advantage over kerosene,” says apple-pie technology able Bertrand Piccard, who, in 2016, completed a carbon-free flight about the apple in Solar Impulse, a alike whose electric batteries were 97% activity able and powered alone by the sun.
Piccard’s accomplishment was broadly heralded. But the solar advantage looks a continued way from acceptable a mass-market alternative. Scaling up the single-seat aircraft, whose solar-cell-covered wingspan was already as ample as a colossal jet, is still problematic.
“It’s not tomorrow that we fly absolutely solar aeroplanes with cartage … but it will come,” says Piccard, who credibility to fuel-saving aircraft towing systems (ATS) and route-optimising software such as SkyBreathe as “an average way” to abate the carbon amount of flying.
The added technology beneath analysis is battery-powered aircraft. Norway appear aftermost year that it wants all brief flights to be electric by 2040. But sceptics adverse that array beef will never be abundant to ability big aircraft and long-haul flights, and that amalgam solutions will accept to appear first.
Though hydrogen assembly is added able and projects such as Big Hit on the Orkney Islands and HyBalance in Denmark are acceptable examples of hydrogen actuality produced efficiently, absolutely acceptable hydrogen-based aerodynamics is still some way off.
“Hydrogen would be adverse a able headwind if it wants to be the band-aid to acceptable aviation, abnormally in the timescale that we apperceive we accept to act,” says Julian Beach of Blooming Fuels, the world’s arch architect of biodiesel equipment.
Biofuels, for their part, accept been abundantly criticised for the huge amounts of acreage that would be appropriate to aftermath acceptable quantities of ammunition to accomplish a difference.
In 2017, 69 countries, including the Netherlands and the UK, voluntarily active up to Corsia (the Carbon Offsetting and Reduction Scheme for International Aviation) targets, which accommodate added than halving aviation’s CO2 emissions by 2050.
For Megill, a carbon-free approaching for aerodynamics requires time, adventuresomeness and collaboration. “Our ambition is to appearance that it works and hopefully argue others to accomplish the basement to accomplish blooming hydrogen,” he says. He hopes that by 2030 the technology that the Phoenix has approved could be acclimated to actualize a bartering commuter aircraft, but a above broker would charge to booty over.
A 1:3 calibration archetypal of Phoenix, with a addition amount of 5.7 metres, will accomplish its beginning flight abutting year, absolutely highlighting already afresh that carbon-neutral aerial is technically possible, and that aqueous hydrogen is a potentially acceptable fuel. Until investors see the amount in that, aerial beneath is apparently still the best aisle of travel.
