fuel cell vs. battery power: which is better? - battery power storage
Battery power or hydrogen fuel cells: this will lead to our gasolinefree driving?
In terms of sales and acceptance, battery power is far ahead.
Most major manufacturers have electric cars in their showrooms, or close to the market like Chevrolet Bolt.
Tesla's Model S, one of the world's most popular cars, has attracted nearly 400,000 people to deposit $1,000 into the still-developing Model 3.
But interest in fuel cells is accelerating.
Toyota, Honda and Hyundai have models available for lease;
Others are working on the technology.
The numbers are small and each trading company loses one.
But the technology works well;
The main barrier, fuel
Cell supporters say there is a lack of hydrogen.
As I wrote last week, there is only one station in Ontario: The only other station in Canada is in B. C.
At present, the only pump in this province only supplies a modified modern Tucson. Number of us. S.
The hydrogen station is actually falling;
It rose from 63 in 2009 to 39 last year.
Which one is more useful?
Battery life is improving, but it is still limited: With the exception of the $130,000 Model S, the current maximum range is about 300 kilometers.
It takes at least half an hour to charge an electric car if 480-1volt fast-
The charger is available and the vehicle is equipped to handle it.
Or a few hours. Fast-
Although the number is growing rapidly, there are still very few charging stations.
This is not a problem if your usual driving range is within the car range.
You just plug in the power at home and charge it overnight.
It's much more convenient than going to a gas station.
However, for a longer trip, you need a non-Battery vehicle. Fuel-
Battery cars run like internal combustion engine-driven cars: they refuel in three minutes, and each car has a refueling time of 500 km kilometers or more, which means that one car can satisfy every kind of driving.
Unlike batteries, fuel cells do not lose capacity in cold weather.
Which one is greener?
Both technologies avoid harmful emissions, but this is only part of the story.
Of course, the batteries are charged by electricity, so their impact on the environment depends mainly on how it is produced.
It's too dirty if the fuel is coal or oil.
Natural gas is a little better.
The cost of nuclear power is very expensive and causes a large amount of radioactive waste.
Water power is green unless it comes from dams that flood large areas of land. Large-
The scale of wind and solar energy can be a hassle, and the construction equipment involves mining and energy.
The hydrogen of the fuel cell can be extracted from the water, which consumes a lot of energy and faces the same problems as the battery.
At the moment, however, natural gas is made of natural gas, which requires steam in the process and therefore requires a lot of energy and emissions of carbon monoxide and carbon dioxide.
In addition to the energy and emissions involved in the extraction and refining of natural gas, this is the most important.
Rare earth metals are needed for batteries;
Platinum fuel cell-
Although the number is decreasing.
The fuel cell is twice as efficient as the internal combustion engine, but still below the battery in this regard. Which wins? Both are —equally —
Greener than the internal combustion engine, but less green than their enthusiasts claim.
Fuel cells that allow a car to meet all driving needs;
A great advantage.
But when there are enough power stations to make hydrogen available, electric vehicles may catch up in the range.
