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.

Here is some raw footage of the HY4 hydrogen electric aircraft being piloted in Slovenia.

GEM eX launched as fully street-legal electric UTV

Waev Inc. has just unveiled the GEM eX, a new electric utility vehicle designed to bridge the gap between street-legal low-speed vehicles (LSVs) and true off-road work machines. The company calls it the most versatile electric work UTV yet.

Unlike most golf cart–based UTVs or high-speed recreational rigs, the GEM eX is purpose-built for commercial, industrial, and government fleets that need to move between city streets, job sites, and rough terrain, all while staying emissions-free.

The vehicle features a top speed of 25 mph (40 km/h) and is said to be DOT street-legal as an LSV on roads up to 35 mph (56 km/h), giving it a clear advantage over most off-road-only competitors.

Power is provided by a 6.5 kW motor in a rear-wheel drive setup with a limited-slip rear differential. An 8 kWh battery provides enough juice for a claimed maximum range of 85 miles (137 km).

The eX comes with several fleet-focused safety and utility upgrades, including 3-point seat belts, roof crush protection, backup camera, mirrors, pedestrian noise emitter, and a robust bumper system. It rolls on street, winter, or all-terrain tires, and the chassis features 9.5 inches (24 cm) of ground clearance, 6.5 inches (16.5 cm) of suspension travel, and a 50-degree approach angle for climbing curbs or crossing uneven work terrain.

Hill-hold assist and single-pedal descent control make it easy to handle on slopes, while a limited-slip differential helps maintain traction without chewing up turf.

In the back, a 1,250 lb (567 kg) composite dump box can fit a full-sized pallet and comes with gas-assist or electric lift options, while towing capacity matches that at 1,250 lb (567 kg). Optional hard doors, roll-down windows, and HVAC with heat and A/C turn it into a true all-weather workhorse.

The lithium iron phosphate battery pack is said to provide a long lifespan for extra durability in extreme climates from –20°F to 140°F (–29°C to 60°C). Charging is flexible via 120V, 240V, or J1772 public stations, and Waev backs the battery with a 7-year warranty – on par with many passenger EVs.

“We field-tested the GEM eX everywhere from Arizona deserts to Minnesota winters,” said Sven Etzelsberger, Waev’s Director of Engineering. “Every piece of customer feedback went back into this vehicle. The result is a work UTV that’s refined, reliable, and ready to go.”

The GEM platform has expanded significantly over the years, from its humble beginnings as a simple people mover to more recent adaptations into everything from ambulances and emergency vehicles to the new GEM eX electric UTV.

Priced at $24,955, the higher purchase price may be one of the few downsides to the quieter, cleaner, and easier to maintain alternative to traditional gasoline-powered UTVs.

Electrek’s Take

Waev’s new GEM eX seems to hit a sweet spot that’s been missing – a street-legal, electric work UTV tough enough for real jobs yet affordable and easy to maintain. For fleet managers juggling both paved and off-road environments, this could be a serious game-changer.

While the price is high, it comes in at significantly less than other well-known models like Polaris’ Zero-powered electric RANGER UTV.

At the same time, there are still more affordable options like those from KANDI that offer more power for a lower price. However, without GEM’s storied brand legacy and increased national support, cheaper options may not have the staying power to compete.

So sure, it’s expensive, but at least I’m glad to see more options coming to the market, especially from brands that have been around for years. Here’s to hoping for more affordable options in the future.

In a first, renewables generate more power than coal globally

In a first, renewables generate more power than coal globally

Solar and wind power aren’t just keeping up with global electricity demand anymore – they’re pulling ahead. According to a new analysis from energy think tank Ember, solar and wind combined outpaced global electricity demand growth in the first half of 2025. That shift led to a drop in both coal and gas generation compared to the same period last year. For the first time ever, renewables generated more power than coal globally.

“We’re seeing the first signs of a crucial turning point,” said Małgorzata Wiatros-Motyka, senior electricity analyst at Ember. “Solar and wind are now growing fast enough to meet the world’s growing appetite for electricity. This marks the beginning of a shift where clean power is keeping pace with demand growth.”

Solar leads the charge

Global electricity demand rose 2.6% in the first half of 2025 – an additional 369 terawatt-hours (TWh) year-over-year. Solar met a stunning 83% of that increase, growing by 306 TWh, or 31% year-over-year. Combined with steady wind expansion, renewables were able to meet rising demand and start displacing fossil fuels.

Coal generation fell 0.6% (-31 TWh), gas dropped 0.2% (-6 TWh), and overall fossil generation declined 0.3% (-27 TWh). As a result, global power sector emissions fell by 0.2%.

Renewables supplied 5,072 TWh of electricity in the first half of 2025 – up from 4,709 TWh a year earlier. Coal, by comparison, generated 4,896 TWh, down 31 TWh year-over-year. It’s the first time on record that clean energy has overtaken coal.

A global turning point

Ember’s analysis shows this is more than a blip. Solar and wind are now growing fast enough to meet new demand and begin cutting into fossil generation. As deployment accelerates, Ember expects clean power to outstrip demand growth for longer stretches, pushing fossil fuels into permanent decline.

But progress isn’t uniform across the globe. Among the world’s four biggest power markets – China, India, the US, and the EU – two saw fossil generation fall, while two saw it rise.

China remains the global clean energy powerhouse, adding more solar and wind capacity than the rest of the world combined. Its fossil generation fell 2% (-58.7 TWh) in the first half of 2025.

In India, clean power growth outpaced demand threefold. With electricity demand rising just 1.3% (+12 TWh) – far below the 9% surge seen last year – fossil generation dropped sharply: coal fell 3.1% (-22 TWh) and gas plunged 34% (-7.1 TWh).

In contrast, fossil generation rose in the US and EU. In the US, demand grew faster than renewables could keep up, leading to higher fossil fuel output. In the EU, weaker wind and hydro performance meant more gas and coal were needed to fill the gap.

What comes next

With half the world already past the peak of fossil fuel generation, Ember says the trend is clear: Clean power can keep up with rising electricity demand. But to lock in progress, deployment of solar, wind, and batteries needs to accelerate.

“Solar and wind are no longer marginal technologies – they’re driving the global power system forward,” said Sonia Dunlop, CEO of the Global Solar Council. “The fact that renewables have overtaken coal for the first time marks a historic shift. But to secure it, governments and industry must step up investment in clean energy and storage so affordable, reliable power reaches everyone.”

Ember’s Wiatros-Motyka added, “With technology costs continuing to fall, now is the perfect moment to embrace the economic, social, and health benefits that come with increased solar, wind, and batteries.”
