We make radically different hydrogen electric cars. Circular business model that prioritises long-lasting vehicles built with advanced, lightweight materials. MaaS. 🇬🇧 Testing underway in the UK now, scaling up with regional manufacturing plants next.
Cardiff is the first UK council to charge more for parking big cars. ☝️London, it’s your turn…
🚙💨 Heavy cars like SUVs = more pedestrian fatalities, less space for others, higher resource consumption, higher energy consumption on the road and more NEEs – whatever powertrain is used.

Our vehicles are still providing the most impressive data on our hydrogen fuel cell powertrains; so we’re celebrating H2 this morning, with some routine testing after our meeting.

Big vehicles have a heavy cost. For every life saved by being in an SUV or pickup truck, 4.3 other lives are lost; for the heaviest 1% of SUVs or trucks, this ratio soars to 12:1.
We’re opting out of the pointless race towards ever vehicle size and power.

We’re well into UK Clean Air Month, and we’ve been enjoying a fresh, zero-emission drive in our hydrogen powered fuel cell car, the Rasa.
The Rasa weighs in at around 660kg. This means low particulate emissions, as well as zero from the tailpipe. 🪻

⚡️The Rasa uses supercapacitors for acceleration + storing recovered energy.
♾️ When the car brakes, kinetic energy normally lost in the form of heat is captured as ⚡️ and as the car slows, this floods into the supercaps + is sent back to the motors, allowing acceleration from 0-60 in 9.5 secs.
