Sentences with phrase «depleted oil or gas»

In Australia carbon dioxide could theoretically be sequestered in depleted oil or gas fields (not expected to be sufficiently depleted until 2030), deep underground unmineable coal seams, or deep saline aquifers.

There has been much ado about flashier carbon - capture systems, like geologic sequestration, which involves collecting carbon dioxide and injecting it deep below the Earth's surface — into depleted oil or gas wells, for example.

Its age is not unusual, considering that all of California's underground natural gas storage facilities are located in depleted oil or gas reservoirs.

Not exact matches

Depleted oil and gas reservoirs and aquifers could leak hydrogen, and cycling — filling a storage site, pulling hydrogen out for use and refilling the site — can't be done more than once or twice a year to preserve the integrity of the rock formation, Lord said.

They looked both at wells used for enhanced oil recovery — in which fluid is injected to flush lingering oil from a depleted reservoir — and at those used to dispose of wastewater from conventional oil and gas extraction or from hydraulic fracturing (fracking).

Moreover, there are two main kinds of geological formation that can be used for CO2 storage: depleted oil and gas fields, and saline aquifers (groundwater bodies whose salt content makes them unsuitable for drinking water or agriculture).

Carbon capture and storage, or CCS, is a family of technologies and techniques that enable the capture of carbon dioxide (CO2) from fuel combustion or industrial processes, the transport of CO2 via ships or pipelines, and its storage underground, in depleted oil and gas fields and deep saline formations.

The ratio of energy returned on energy invested (EROEI) for fossil energy production has tended to fall as high - quality deposits of oil, coal, and natural gas are depleted, and as society relies more on unconventional oil and gas that require more energy for extraction, and on coal that is more deeply buried or that is of lower energy content.

The UK has the advantage here because it can store the carbon dioxide under the sea — in depleted oil and gas fields or alternatively saline aquifers, where the carbon dioxide would be partially dissolved in salt water.
