Zero emission aircraft powertrain developer H2FLY is celebrating a major milestone in what it is hailing as a world’s first. The company has successfully piloted a flight of an electric aircraft powered by liquid hydrogen rather than gas, opening a new door of opportunity for zero-emissions long distance flights.
H2FLY is a Stuttgart, Germany-based company that specializes in the development of hydrogen electric aviation technology – more specifically, liquid hydrogen – with hopes of becoming one of the first to deliver a qualified propulsion system to market. It has the support of Joby Aviation, an eVTOL developer we often cover than acquired H2FLY in 2021.
Today’s news may be a world’s first, but H2FLY has already delivered several firsts compared to other zero-emission aviation companies. For instance, its HY4 hydrogen electric aircraft completed its maiden flight all the way back in 2016 and broke a world record in 2022 when it soared above 7,000 feet in the sky during a 77-mile journey across Germany.
Thanks to nearly a decade of experience, H2FLY has garnered the financial support of multiple German ministries as well as Project HEAVEN – a consortium of aviation specialists including the German Aerospace Center supported by the EU government to demonstrate the feasibility of liquid, cryogenic hydrogen use in aircraft.
Following its most recent voyage with a pilot, H2FLY has offered a potentially groundbreaking demonstration that enables longer range and higher payloads.
H2FLY demonstrates viability of hydrogen electric aircraft
The hydrogen powertrain developer shared details of its latest aerial voyage test campaign which included four separate flights in the HY4 demonstrator electric aircraft, which was piloted by a human inside for the first time ever.
Rather than use pressurized gaseous hydrogen storage (GH2) like the past, the HY4 electric aicraft was powered by cryogenically stored liquid hydrogen (LH2), enabling significantly lighter tank weight and volume. H2FLY shared that as a result, its hydrogen-electric fuel cell propulsion system will be able to double the maximum range of the HY4 aircraft for instance, from 750 km (466 miles) to 1,500 km (932 miles). H2FLY cofounder Professor Josef Kallo spoke to the breakthrough:
This achievement marks a watershed moment in the use of hydrogen to power aircraft. Together with our partners, we have demonstrated the viability of liquid hydrogen to support medium and long-range emissions-free flight. We are now looking ahead to scaling up our technology for regional aircraft and other applications, beginning the critical mission of decarbonizing commercial aviation.
Looking ahead, H2FLY will continue its progress toward commercialization alongside the development of its new H2F-175 fuel cell systems which are expected to propel aircraft to full power range at altitudes up to 27,000 feet. The company’s future work will emerge from its new Hydrogen Aviation Center at Stuttgart Airport, set to open next year.

Global mining and construction equipment giant Liebherr recently rolled out its first-ever battery electric crawler excavator, setting a new standard in heavy earth-moving equipment capabilities with low noise levels and zero local emissions.
The company’s official copy is characteristically low-key, with an emphasis on the facts and features instead of hype:
The new model completes the product range of Liebherr crawler excavators produced in Colmar (France). It is particularly quiet and emission-free. It generates the same output as a diesel machine in the same category and is particularly suitable for building sites that require low noise levels and avoiding exhaust gas emissions, such as in cities or underground operating locations.
Despite the lack of excitement in the release copy, there is a lot of excitement about the R 920 G8-E’s innovative new control cab philosophy.

Liebherr INTUSI controls
Dubbed INTUSI (for INTuitive USer Interface), the system integrates intelligent control logic with advanced machine learning capabilities to give operators a highly customizable interface that can follow them from asset to asset, from wheel loader to excavator to haul truck, dramatically flattening the learning curve for operators on a given job site.
Liebherr says INTUSI improves both operational efficiency and user comfort on Liebherr job sites through the integration of a number of new features. From the press release:
Haptic feedback – vibrations alert the operator to critical conditions—such as reaching dynamic device limits—enhancing situational awareness and speeding up reaction times.
Optical feedback – integrated RGB LEDs on the joystick provide real-time visual cues about device status and servo control, ensuring clear communication without distraction.
Functional safety – control elements with status LEDs allow safe operation of critical functions—without requiring two-handed input—streamlining workflow while maintaining safety standards.
Hand detection – capacitive proximity sensor detects the operator’s hand automatically, enabling seamless activation of controls only when needed.
Display navigation – a mini-joystick embedded in the handle allows for quick and efficient navigation of the display interface, reducing the need to reach for external controls.
Ergonomics – multi-stage handle height adjustment ensures optimal comfort and usability, adapting to different operator preferences and working conditions
In addition to the INTUSI-powered custom cockpit, the new Liebherr R 920 G8-E electric excavator ships with your choice of either a 188 or 282 kWh high capacity li-ion battery, which is capable of 150 kW DC fast charging. Fast enough, in other words, to power up the machine during shift changes, if needed.
Electrek’s Take
R 920 G8-E electric crawler excavator; via Liebherr.
Since then, Fortescue has used the machine to move millions of tons of dirt, and has ordered several more. And, because everything from excavators to loaders to heavy trucks are built to be powertrain agnostic, and manufacturers will often offer the same basic vehicle with Cummins, Detroit Diesel, or Volvo power, so there’s a degree of openness baked into those systems already. Liebherr is just taking that to the next level by installing an electric drive motor in place of an internal combustion engine, and I expect this excavator will be the first of many such machines from the brand.

Rivian has posted a job listing for a steering engineer, specifically mentioning work on a future steer-by-wire system for the company.
Steer-by-wire is an automotive concept that has been around for a long time, but hasn’t yet reached mass adoption. The idea is to replace (or supplement) mechanical linkages between the steering wheel and the wheels with electronic actuators instead.
There are a number of potential benefits to this, like allowing more customizability or adaptability to a steering system, reducing mechanical complexity, or adding speed-sensitive variable steering ratios.
Although there are also disadvantages, like a reduction in steering feel (although, since most cars are moving to electronic power steering, that was already gone anyway).

But few cars have implemented steer-by-wire systems, or at least not fully committed to them, given that mechanical steering racks are a relatively solved problem and the general inertia of the car industry which would rather stick with a solution they know than switch to something better (haven’t we here, at this EV publication, heard *that* one before…). There’s also the matter of regulations, which have often been written to require mechanical steering systems, and may need updating to allow for steer by wire.
But, steer by wire made it into mass production with the release of the Tesla Cybertruck. This was big news when Tesla committed to this – at the time, it was the only thing on the road to exclusively use a steer by wire system, though there are other cars with partial steer by wire (for example, mechanical front wheel steering, and steer by wire rear-wheel steering).
But it seems to have opened the floodgates, as a number of other companies are working on or have since released steer by wire systems (Lexus, for example).
And now, it looks like Rivian is one of those companies – though we don’t know if it’s for the front or rear.
So – we know they’re working on steer by wire, to some extent.
But a few other EVs, particularly large EVs like the Rivian R1 platform is, use steer by wire just for the rear wheels – for example the Hummer EV and Rolls-Royce Spectre. These systems are particularly helpful for giant vehicles, because it allows them to be more nimble and make turns that otherwise would require a lot more… negotiation in a giant land yacht.
So it’s possible that Rivian is only working on rear wheel steer by wire here, but we’d like to think there’s a chance it’s working on steer by wire for the full vehicle.
We also don’t know if this would show up on all of Rivian’s vehicles, or only on certain models – the R2 and R3 are in development, and the R1 just got a big refresh. But, perhaps even more interestingly (and very speculatively), VW has invested heavily in Rivian for technology help, so we wonder if we might end up seeing this in VW group vehicles, or Scout vehicles eventually…
