technology, and applications of hydrogen energy. Hydrogen is the simplest chemical element, or type ofatom, and an abundance of hydrogen exists within the water on our planet. It is naturally renewed by the water cycle, and when used as fuel, it releases no harmful emissions. For these...

Step-by-Step Text Solution:1. High Energy Efficiency: Hydrogen as a fuel has a very high energy efficiency, typically greater than 80%. In comparison, gasoline and coal have energy efficiencies that are equal t
A hydrogen fuel cell operates through an electrochemical process that transforms the energy stored in hydrogen gas (H2) and oxygen into electrical power without combustion. The magic happens in what is known as the fuel cell stack that is responsible for facilitating the electrochemical reactions, wh...
after carbon dioxide.In the United States, over two-thirds of natural gas comes from hydraulic fracturing, also known asfracking.The remaining percentage is a byproduct of crude oil drilling. Compressing natural gas reduces it to 1% of its original volume, making it usable as a transportation ...
The common thread shared by all biodiesel produced is that they all contain fat in some form. Oils are just fats that are liquid at room temperature. Thesefats, or triacylglycerols (sometimes called triglycerides) are made up of carbon, hydrogen, and oxygen atoms bound together and arranged int...
Which of the following is the best sink for atmospheric methane? A) The greenhouse gases. B) The carbon bases located on land. C) The hydrogen radical in the ocean. D) Hydroxyl radical in the troposphere. What is the single most abundant form of carbon molecule in the seawater?
It occurs both naturally and as a byproduct of human activities, such as burning fossil fuels.Today, the world is undertaking the net-zero transition, an ambitious effort to reach net-zero emissions of CO2 and reduce emissions of other GHGs. The goal of the transition is outlined in the ...
What is the relationship between cellular respiration and photosynthesis? What happens to the oxygen that is produced as a result of photosynthesis? What are the differences between cellular respiration and photosynthesis? What is the common byproduct for cellular respiration and photosynthesis?
If cellulosic biomass is the feedstock, there is a tradeoff between the amount of biomass and hydrogen needed to produce a unit of hydrocarbon liquid product. Recent studies [[1], [2]] indicate the potential for the U.S. to produce up to 30 million barrels per day of liquid hydrocarbons...
