Hydrogen, hydrogen energy, hydrogen fuel; Hydrogen sulfide

At standard temperature and pressure it is a colorless, odorless, nonmetallic, univalent, tasteless, highly flammable diatomic gas. Having been used as an ingredient in some rocket fuels for several decades, hydrogen, or more specifically H2, is now widely discussed in the context of energy. Hydrogen is not an energy source, since it is not an …

Hydropower

Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy. Hydropower is the most common of renewable energy sources used to generate electricity

Improved recovery; Improved oil recovery

Improved recovery is the extraction of additional petroleum beyond primary recovery, from naturally occurring reservoirs by supplementing the natural forces in the reservoir. It includes water flooding, secondary processes, tertiary processes and any other means of supplementing natural reservoir recovery processes. Technology advances in IOR/EOR may prove to be what staves off the “peak” in …

In situ oil shale recovery; In situ oil shale production method

Oil shale can be mined and processed to generate oil similar to oil pumped from conventional oil wells; however, extracting oil from oil shale is more complex than conventional oil recovery and currently is more expensive. The oil substances in oil shale are solid and cannot be pumped directly out of the ground. The oil …
