Hydrogen fuel cars never caught on, but it just might produce next-gen long range drones


Hydrogen power never found a home in your car, but it might finally have its moment inside a drone. Researchers in Norway have built a heavy-lift drone that runs on hydrogen, ditching batteries for a fuel cell to tackle the range problem that keeps most commercial drones grounded.

The prototype from SINTEF, a Scandinavian research institute, targets jobs where battery-powered drones fall short. Think inspecting remote power lines after a storm or searching for missing hikers in bad weather. Senior research scientist Federico Zenith says the goal isn’t to replace your weekend flyer. It’s to handle missions today’s drones simply cannot reach.

Why fuel cells beat batteries and gas

Instead of building from zero, the SINTEF team started with a heavy battery-powered model and swapped in a fuel cell and hydrogen tank. Zenith calls the conversion straightforward, a path that could let operators upgrade existing gear rather than buy all new.

Right now, their prototype is a rare sight. According to Zenith, it’s the only hydrogen drone flying in Norway and, as far as the team knows, the only one in all of Scandinavia. That makes the institute a rare test case for what hydrogen can actually do for flight times.

The fuel cell also beats the gas-powered alternative. Traditional engines need frequent replacements and heavy maintenance. A fuel cell, Zenith says, runs for at least a thousand hours and is easier to swap when it finally wears down.

Where hydrogen drones actually make sense

Longer flight times open up high-stakes work. The SINTEF team sees the hydrogen prototype handling power line inspections after storms, a job that today often requires a helicopter. If a tree falls on a line during bad weather, sending up a crew is risky. A hydrogen drone could launch immediately and help restore power faster.

Search and rescue is another clear fit. The same range that lets a drone follow power lines from transformer to transformer also lets it scan vast areas for a lost hiker. The researchers also mention mapping, monitoring snowpack for flood forecasts, and keeping an eye on landslides.

The financial math shifts here too. A fuel cell is still expensive, Zenith admits. But compared to staffing a helicopter for the same mission, the drone becomes the cheap option. That math might finally give hydrogen the foothold it never found in passenger cars.

What comes next for hydrogen flight

The hydrogen drone has flown, but it can’t handle a real Norwegian winter yet. The fuel cell inside the prototype is only rated for use above freezing and in dry conditions, which means, as Zenith points out, there aren’t many flyable days in Trondelag county right now.

Weatherproofing is the next big task. The SINTEF team is actively looking for funding and partners to tackle that work, aiming to see how many hours they can keep a drone airborne in real northern conditions, not just a lab.

The potential here is clear. If they can solve the weather problem, hydrogen drones could quietly take over the jobs that are too far, too dangerous, or too expensive for helicopters and battery packs. The tech that stalled on the highway might finally find its purpose in the sky.

Google Maps has a long list of hidden (and sometimes, just underrated) features that help you navigate seamlessly. But I was not a big fan of using Google Maps for walking: that is, until I started using the right set of features that helped me navigate better.

Add layers to your map

See more information on the screen

Layers are an incredibly useful yet underrated feature that can be utilized for all modes of transport. These help add more details to your map beyond the default view, so you can plan your journey better.

To use layers, open your Google Maps app (Android, iPhone). Tap the layer icon on the upper right side (under your profile picture and nearby attractions options). You can switch your map type from default to satellite or terrain, and overlay your map with details, such as traffic, transit, biking, street view (perfect for walking), and 3D (Android)/raised buildings (iPhone) (for buildings). To turn off map details, go back to Layers and tap again on the details you want to disable.

In particular, adding a street view and 3D/raised buildings layer can help you gauge the terrain and get more information about the landscape, so you can avoid tricky paths and discover shortcuts.

Set up Live View

Just hold up your phone

A feature that can help you set out on walks with good navigation is Google Maps’ Live View. This lets you use augmented reality (AR) technology to see real-time navigation: beyond the directions you see on your map, you are able to see directions in your live view through your camera, overlaying instructions with your real view. This feature is very useful for travel and new areas, since it gives you navigational insights for walking that go beyond a 2D map.

To use Live View, search for a location on Google Maps, then tap “Directions.” Once the route appears, tap “Walk,” then tap “Live View” in the navigation options. You will be prompted to point your camera at things like buildings, stores, and signs around you, so Google Maps can analyze your surroundings and give you accurate directions.

Download maps offline

Google Maps without an internet connection

Whether you’re on a hiking trip in a low-connectivity area or want offline maps for your favorite walking destinations, having specific map routes downloaded can be a great help. Google Maps lets you download maps to your device while you’re connected to Wi-Fi or mobile data, and use them when your device is offline.

For Android, open Google Maps and search for a specific place or location. In the placesheet, swipe right, then tap More > Download offline map > Download. For iPhone, search for a location on Google Maps, then, at the bottom of your screen, tap the name or address of the place. Tap More > Download offline map > Download.

After you download an area, use Google Maps as you normally would. If you go offline, your offline maps will guide you to your destination as long as the entire route is within the offline map.

Enable Detailed Voice Guidance

Get better instructions

Voice guidance is a basic yet powerful navigation tool that can come in handy during walks in unfamiliar locations and can be used to ensure your journey is on the right path. To ensure guidance audio is enabled, go to your Google Maps profile (upper right corner), then tap Settings > Navigation > Sound and Voice. Here, tap “Unmute” on “Guidance Audio.”

Apart from this, you can also use Google Assistant to help you along your journey, asking questions about your destination, nearby sights, detours, additional stops, etc. To use this feature on iPhone, map a walking route to a destination, then tap the mic icon in the upper-right corner. For Android, you can also say “Hey Google” after mapping your destination to activate the assistant.

Voice guidance is handy for both new and old places, like when you’re running errands and need to navigate hands-free.

Add multiple stops

Keep your trip going

If you walk regularly to run errands, Google Maps has a simple yet effective feature that can help you plan your route in a better way. With Maps’ multiple stop feature, you can add several stops between your current and final destination to minimize any wasted time and unnecessary detours.

To add multiple stops on Google Maps, search for a destination, then tap “Directions.” Select the walking option, then click the three dots on top (next to “Your Location”), and tap “Edit Stops.” You can now add a stop by searching for it and tapping “Add Stop,” and swap the stops at your convenience. Repeat this process by tapping “Add Stops” until your route is complete, then tap “Start” to begin your journey.

You can add up to ten stops in a single route on both mobile and desktop, and use the journey for multiple modes (walking, driving, and cycling) except public transport and flights. I find this Google Maps feature to be an essential tool for travel to walkable cities, especially when I’m planning a route I am unfamiliar with.


More to discover

A new feature to keep an eye out for, especially if you use Google Maps for walking and cycling, is Google’s Gemini boost, which will allow you to navigate hands-free and get real-time information about your journey. This feature has been rolling out for both Android and iOS users.
