Blooms are large and elongated cast pieces of steel that are cut-to-length immediately after casting. After reheating, blooms are used to roll medium and large sections, as well as large profiles such as sheet piling, and rails. 

To vent gas from a well or production system. Wells that have been shut in for a period often develop a gas cap caused by gas percolating through the fluid column in the wellbore. It is often desirable to remove or vent the free gas before starting well intervention work.

An uncontrolled flow of reservoir fluids into the wellbore, and sometimes catastrophically to the surface. A blowout may consist of salt water, oil, gas or a mixture of these. Blowouts occur in all types of exploration and production operations, not just during drilling operations.

A large valve at the top of a well that may be closed if the drilling crew loses control of formation fluids. These high pressure valves are designed to shut off the uncontrolled flow of hydrocarbons.

Blue hydrogen is derived from natural gas through the process of steam methane reforming (SMR). SMR mixes natural gas with very hot steam, in the presence of a catalyst, where a chemical reaction creates hydrogen and carbon monoxide. Additional water is added to the mixture converting the carbon monoxide to carbon dioxide and creating more hydrogen. The carbon dioxide emissions produced are then captured and stored leaving nearly pure hydrogen.

Blue hydrogen follows the same same process as grey hydrogen, except for the additional step where the the carbon is captured and stored.

Body in white refers to the stage in automotive design or automobile manufacturing in which a car body's sheet metal components have been welded together. This process occurs before painting and before moving parts have been added. Both hot and cold rolled steel coil, most or all of it galvanized, is used to fabricate the parts that make up the body in white.

The balance of plant in a fuel cell system is the auxiliary equipment requires to ensure the fuel cell operates as a reliable power source. This may include fuel reformers and pumps,for example

A borehole is a narrow shaft, bored in the ground, either vertically or horizontally. A borehole may be constructed for many different purposes, including the extraction of water or other liquid (such as petroleum) or gases (such as natural gas). As well as pumping petroleum from an underground well through a borehole, liquid or gas can be pumped into it, for that process, or for underground storage of unwanted substances. 

Boron is a chemical element with the symbol B and atomic number 5. Produced entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, it is a low-abundance element in the Solar System and in the Earth's crust. It constitutes about 0.001 percent by weight of Earth's crust. Boron can be added to Li-ion battery electrodes, and when combined with other stabilization strategies such as protective coatings, could boost the energy density and stability needed to push the driving range per charge of EVs beyond the 300-mile mark.

Brown Hydrogen comes from brown coal, also known as Lignite. This ‘younger’ coal contains a considerably higher percentage of oxygen and hydrogen than the more familiar and older, black variety. The ‘gassification’ of brown coal creates a synthesis gas which is a mix of mainly carbon monoxide with hydrogen, steam and carbon dioxide. This syngas is then cleaned in conventional ways to recover the hydrogen but that then leaves a considerable volume of greenhouse gases to deal with. Using black coal or lignite (brown coal) in the hydrogen-making process, these black and brown hydrogen are the absolute opposite of green hydrogen in the hydrogen spectrum and the most environmentally damaging. 

Clean steel scrap consisting of sheet clips and stampings from metal production. This is applied to thin uncoated clippings and stamping offcuts from manufacturing operations. Consequently it only applies to new production scrap, rather than scrap generated from obsolete used items.
