What did Elon Musk say about hydrogen cars?

“Green hydrogen is needed for steel, chemical, aero … and should not end up in cars. Far too expensive, inefficient, slow and difficult to rollout and transport. After all: no #hydrogen cars in sight.”

What is the main problem in using hydrogen as fuel?

The only real problem is the issue of safety. Hydrogen is highly flammable – more so than regular fuel – and is harder to contain than oil. This means that any car fitted with hydrogen fuel cells is a lot more likely to blow up or set on fire if it is exposed to extreme heat, if it breaks down or if it overheats.

What are some drawbacks or obstacles to using hydrogen fuel cells?

List of Disadvantages of Hydrogen Fuel Cells

• It is expensive. While widely available, hydrogen is expensive.
• It is difficult to store. Hydrogen is very hard to move around.
• It is not easy to replace the existing infrastructure.
• It is highly flammable.
• Fossil fuels are often used to produce it.

Why Elon Musk is wrong about hydrogen fuel cells?

Musk HATES the idea of using hydrogen energy to power vehicles. He’s called them “fool cells.” And says using them to power vehicles is “mind-bogglingly stupid.” His basic objection is that using hydrogen to store energy can never be as efficient as storing electricity in a battery.

Why is Elon Musk against fuel cells?

Clearly, Musk is not a fan of hydrogen fuel cells — at least not for use in cars — which makes sense since he built the Tesla empire on lithium-ion batteries. It’s not a source of energy,” Musk said at a 2015 press conference. “Electrolysis is extremely inefficient as an energy process.

How does hydrogen fuel cells work?

In a fuel cell, hydrogen and oxygen are combined to generate electricity, heat, and water. A typical fuel cell works by passing hydrogen through the anode of a fuel cell and oxygen through the cathode. At the anode site, a catalyst splits the hydrogen molecules into electrons and protons.

Why is hydrogen a good fuel?

However, hydrogen is useful as an energy source/fuel because it has a high energy content per unit of weight, which is why it is used as a rocket fuel and in fuel cells to produce electricity on some spacecraft. Hydrogen is not widely used as a fuel now, but it has the potential for greater use in the future.

Is hydrogen fuel cell safe?

Is Hydrogen Fuel Safe? The short answer is that hydrogen behaves differently from gasoline. But generally it is about as safe as the gasoline we now put in most vehicles’ fuel tanks.

Are hydrogen fuel cell vehicles safe?

Fuel Cell Electric cars are as safe as conventional vehicles. Toyota has spent many years testing hydrogen-powered cars in extreme conditions and temperatures to ensure they can be used safely and reliably, just like any other Toyota. Hydrogen itself is clean, safe and all around us.
