Currently, hydrogen demand is driven largely by the fertilizer and refining industries. Looking ahead, industries that rely heavily on fossil fuels, such as heavy industries and long-haul transport, stand to benefit the most from hydrogen energy in the short term. The steel industry, which account...
The demand for hydrogen as an energy source is expected to increase by more than seven times by 2040. However, hydrogen is not naturally available in a usable form for energy storage technology; rather, it must be produced by chemical processes, giving rise to some financial, technical, and ...
aSuch a practice not only increases expenses (i.e., payments to the wastewater treatment plants for treatment and increased concentrations of chemical oxygen demand (COD) and nutrients, penalties to the ecologic authorities) but also severely damages the environments and leads to nonrational usage of...
One may of making hydrogen is a process called electrolysis, when electricity is passed through a substance to force a chemical change — in this case, splitting H2O into hydrogen and oxygen. Green hydrogenis when the energy used to power electrolysis comes from renewable sources like wind, wate...
There are several ways to use hydrogen for energy once it is produced. The most prominent is in fuel cells, which convert the chemical energy stored in hydrogen and oxygen into electricity. Unlike with gasoline-fueled engines, there are no harmful emissions like carbon dioxide. And unlike with...
“Support for supply can come through investment incentives, while demand can be supported through mandates for the use of renewable fuels, as well as by ensuring that the cost of carbon emissions is reflected in fossil fuel pricing.” In addition, it is important for electrical grids, pipelines...

Biochemical oxygen demand (BOD) is the amount of oxygen required to decompose organic pollutants in water, and chemical oxygen demand (COD) is the amount of an oxidant required to decompose the organic pollutants. Both are indicators of organic matter pollution of water. “Development of the U-...
Liquid hydrocarbons Liquid fuel demand Cellulosic biofuels Negative carbon emissions 1. Introduction Unless we find a drop-in replacement for oil, we must not only replace oil but much of the U.S. infrastructure: pipelines, refineries, cars, aircraft, furnaces, chemical processes and a myriad of...
As you can see, a chemical engineer can find a niche in any scientific or engineering field. While the engineer often works in a plant or lab, she's also found in the boardroom, office, classroom, and out at field locations. Chemical engineers are in high demand, so they typically comm...
