Energy storage being held back by oil

Can depleted oil & gas wells be used for energy storage?

The idea is to use depleted oil and gas wells as a reservoir for the storage of compressed natural gas. As needed, the gas can be released to spin a turbine and generate electricity. The reservoir is recharged using excess electricity from the grid and the cycle repeats, providing a potential solution for the growing demand for energy storage.

How long does energy storage last?

After the recovery period, the storage cycle is repeated. In the short term, the process can provide six hours of electricity. For longer, or seasonal, needs, the researchers calculate it can offer90 days of electricity. “Seasonal energy storage is very, very limited,” Young said.

Could pumped hydro revolutionise energy storage?

Quidnet Energy is hoping to revolutionise energy storage with its underground pumped hydro concept, which uses abandoned oil and gas wells to store and release pressurised water, driving turbines and feeding electricity back into the grid. How does the concept work and how far could it go? Quidnet co-founder Aaron Mandell explains.

Why is energy storage so important?

As the cost of renewable energy continues to decline and intermittent clean power sources such as wind and solar gain ever an ever larger foothold in the global energy mix, the ability to store energy that can be quickly dispatched when needed has become as important as the development of renewables themselves.

Why is long duration energy storage a problem?

Large amounts of long duration energy storage (LDES) are needed to achieve the government’s renewable energy goals and deployment is being held back by a lack of supportive market mechanisms, industry experts warned.

How much oil will the Energy Department buy back?

The Energy Department has about $3.67 billion left in its SPR buyback fund, enough to purchase about 46.5 million barrels at the $79 a barrel price, according to ClearView Energy Partners, a nonpartisan research group. The department says it will release monthly plans to buy back oil in increments through at least May.
