Executive summary – The Role of Critical Minerals in Clean Energy Transitions – Analysis - IEA The Role of Critical Minerals in Clean Energy Transitions - Analysis and key findings. A report by the International Energy Agency.

⚡Renewable technology needs many times more critical materials than a hydrocarbon-based world – for wind turbines, solar PV, batteries.

🔋Let’s use critical minerals sparingly in cars – where there are alternatives to big batteries. H2 fuel cell cars use far fewer critical materials.

Canada includes hydrogen FCEVs in EV incentives, omits refuelling support Canada will offer incentives for hydrogen fuel cell electric vehicle (FCEV) purchases under the government’s new automotive strategy, despite no support for hydrogen refuelling.

😀 Canada announces incentives for both fuel cell electric vehicles (FCEVs) and battery electric vehicles (BEVs)

😭 No mention of H2 refuelling – in contrast to a CAD$1.5bn package for EV charging...

BMW bets big on hydrogen – but is it the fuel's last chance to work? | Autocar BMW's third-gen fuel cell system will enter production in 2028

Investment by big firms like BMW, Toyota + incoming infra in Europe are a tipping point for #hydrogen vehicles – challenging the ‘naysayers.’

The piece also characterises these developments as a last chance; but we view it as good, long term business strategy 👇

💧Takes a few mins to refuel

💧If you can’t charge at home (around half of Brits) H2 is ✅

💧Existing forecourts can be adapted for H2

💧Infrastructure has been slow to come, but it’s gaining traction

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.

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.

🏭 Inbuilt obsolescence, depreciation and overcomplexity dominate the current economic system and manufacturing.

♾️ We’re working to a completely different model, a truly circular one – with Mobility as a Service hydrogen cars, made with long-lasting, serviceable components and closed loops.

👀The #hydrogen Rasa turned heads and garnered much attention on the streets outside the @sciencemuseum.org.uk in London yesterday for @imperialcollegeldn.bsky.socialand Wicked Acceleration Labs

☠️ Air pollution is the largest environmental threat to human health.

🚗💨 Cars + vans are the biggest source of emissions.

🚗💧Our #hydrogen electric cars emit nothing but a drop a water from the tailpipe, and as the Rasa is so light and efficient, very low NEEs.

✈ The Rasa is designed to slip through the air with minimal resistance, critical for energy efficiency.

⏥The underside is as smooth as the rest of the body for low drag

✅ Making cars from advanced composites, our minimum efficient scale of production is c.2% of that of conventional auto manufacturers, for whom a steel press tool costs around £1bn.

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. 🪻

🤔Do you know where this is?

We get around over the years…

⚡️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.
