Hydrogen is actually pretty hard to make. It has a horrible well-to-wheel efficiency as a result. Easy ways to get large quantities of hydrogen are not ‘cleaner’ than gasoline. Efficient HFCs have very slow response times, meaning you again need additional systems to store energy for accelerating.
Because hydrogen doesn’t occur naturally, it has to be extracted, then compressed in fuel tanks. It then has to mix with oxygen in a fuel cell stack to create electricity to power the car’s motors. That’s true to an extent, but hydrogen-powered cars are not expected to replace EVs.
Battery electric vehicles, or BEVs, are the electric vehicles that most of us are familiar with today, like Teslas. Fuel-cell vehicles don’t require charging at all. The hydrogen tank is refilled at a hydrogen station in less than five minutes, just like your typical gas station today.Jul 14, 2020
But building a Tesla actually generates more emissions because of the metals needed for its lithium-ion battery. At 20,600 miles, the greenhouse gas emissions from building and driving the two cars are roughly the same, according to the University of Toronto analysis. Then the Tesla pulls ahead.Mar 22, 2021
Arabesque ranked Tesla well behind Ford and General Motors (GM)—two of Tesla’s fiercest American competitors, which have built their success on carbon-intensive combustion engines. Tesla shows its carbon emissions in graphs, which means they do not disclose the exact numbers.May 13, 2021
Today, Tesla builds not only all-electric vehicles but also infinitely scalable clean energy generation and storage products. From there, Tesla designed the world’s first ever premium all-electric sedan from the ground up – Model S – which has become the best car in its class in every category.
