District cooling is a modern, efficient method of air conditioning a network of buildings in cities or campuses. It involves central cooling plants that produce chilled water, which is then distributed to customer buildings through an insulated underground piping network. This system helps reduce strain on the electric grid, balances electric loads, and lowers fuel costs by aggregating the cooling needs of multiple buildings.

Drilling rigs are machines that are used to drill a wellbore at oil and gas reserves for the extraction of hydrocarbons. In onshore drilling, drilling rigs include virtually all components required for the drilling process. While in offshore drilling, drilling rigs include the same components as onshore drilling rigs, but not those of the drilling platforms or vessels themselves. The major components of the drilling rig include a mast or derrick, mud pumps, mud tanks, rotary tables, drillstring, draw works, power generation equipment, and other auxiliary equipment. Oil and gas upstream companies hire drilling rig contractors to drill oil and gas wells.

E-fuels, or electro fuels, are synthetic fuels produced using renewable electricity, water, and captured carbon dioxide. Through a process called Power-to-Liquid (PtL), green hydrogen is generated via electrolysis and then combined with CO2 to create liquid hydrocarbons like synthetic gasoline, diesel, or jet fuel. These fuels are carbon-neutral when produced sustainably and can be used in existing internal combustion engines and fuel infrastructure, making them a promising solution for decarbonizing hard-to-electrify sectors like aviation, shipping, and heavy transport.
