TPO-09 - Integrated Writing Task
Car manufacturers and governments have been eagerly seeking a replacement for the automobile's main source of power, the internal-combustion engine. By far the most promising alternative source of energy for cars is the hydrogen-based fuel-cell engine, which uses hydrogen to create electricity that, in turn, powers the car. Fuel-cell engines have several advantages over internal-combustion engines and will probably soon replace them.
One of the main problems with the internal-combustion engine is that it relies on petroleum, either in the form of gasoline or diesel fuel. Petroleum is a finite resource; someday, we will run out of oil. The hydrogen needed for fuel-cell engines cannot easily be depleted. Hydrogen can be derived from various plentiful sources, including natural gas and even water. The fact that fuel-cell engines utilize easily available, renewable resources makes them particularly attractive.
Second, hydrogen-based fuel cells are attractive because they will solve many of the world's pollution problems. An unavoidable by-product of burning oil is carbon dioxide, and carbon dioxide harms the environment. On the other hand, the only byproduct of fuel-cell engines is water.
Third, fuel-cell engines will soon be economically competitive because people will spend less money to operate a fuel-cell engine than they will to operate an internal-combustion engine. This is true for one simple reason: a fuel-cell automobile is nearly twice as efficient in using its fuel as an automobile powered by an internal-combustion engine is. In other words, the fuel-cell powered car requires only halfthe fuel energy that the internal-combustion powered car does to go the same distance.
The topic discusses the advantages of using a hydrogen-based fuel-cell engine in place of the fuel-cell combustion engine and the author represents various reasons behind why hydrogen fuel engine can solve problems that we face because of fuel cell engine.
The first reason the author presents, fuels are finite and someday we will run out of fuel, and major combustion engines rely on petroleum, either in form of gasoline or diesel fuel. On the other hand, hydrogen can be derived from plentiful sources like water or natural gas. The fuel-cell engines are attractive because it's easily renewable and easily available. The speaker opposes the idea because she thinks the author is way more optimistic and hydrogen is not that easily available. Hydrogen cannot be produced directly from water and in case of using hydrogen as a fuel, hydrogen needs to be stored as liquid hydrogen. Hydrogen is hard to produce and harder to store because it needs to be stored at -253 degree Celcius.
The author represents his second opinion by saying that hydrogen can solve pollution unlike fuel engine produce carbon dioxide and other bicarbonate products. The speaker counters this opinion by saying, it might possible hydrogen engine don't produce carbon dioxide but factories need oil or coal to purify the hydrogen, which causes more carbon dioxide and other bicarbonate products. Thus the idea of the author was not practical.
The third idea the author represents that fuel-cell engines are going to be economical soon as it is more efficient than combustion engine and use half the fuel energy as compared to the combustion engine. The speaker opposes the idea by saying, in case of hydrogen fuel engine platinum used in engines which is a really expensive material. Other materials that were used in place of platinum was not successful. So hydrogen fuel-cell engine is not economical.
