Iraq holds the 12th largest reserves in the world, estimated at 131 trillion cubic feet (Tcf) at the end of 2022, predominantly located in large oil fields in the south and mostly associated with oil production. Despite these substantial reserves, Iraq faces regulatory, investment, and infrastructure challenges, which have kept natural gas production largely unchanged since 2016. The majority of Iraq's natural gas, about two-thirds, is produced as a by. [pdf]
BP plc (BP) announced an agreement with the Iraq government to redevelop the Kirkuk oil and gas fields in northern Iraq, per a Reuters report.
Energy in Iraq plays a crucial role in both the national economy and the global energy markets due to the country's vast oil reserves and significant status within the Organization of the Petroleum Exporting Countries (OPEC). Iraq holds abundant oil and gas resources and has strong solar PV potential.
Iraq consumed significantly more natural gas than it produced in 2021, primarily for electric power generation. The country also flared over 630 billion cubic feet (Bcf) of natural gas in 2022 due to inadequate pipeline and processing infrastructure, making it the second-largest flaring country globally.
Oil provided 85% of government income. Iraq's oil reserves were the third biggest in the world, after Saudi Arabia and Iran. In 2009 the Iraq government set a target to increase oil production from 2.5-million-barrels (400,000 m 3) to 7-million-barrels-per-day (1,100,000 m 3 /d) in six years.
Iraq holds abundant oil and gas resources and has strong solar PV potential. Its production to 2030 is set to be the third largest contributor to global oil supply. By the same year, the government expects that renewable capacity will amount for 5% of the country’s total system capacity.
This has introduced a number of vulnerabilities to Iraq’s energy system. For example, payment issues last summer led to Iran cutting exports, significantly exacerbating electricity shortages in Iraq during peak seasonal demand. As oil production has soared, so has the amount of associated gas produced alongside.

LDES encompasses a group of conventional and novel technologies, including mechanical, thermal, electrochemical, and chemical storage, that can be deployed competitively to store energy for prolonged periods and scaled up economically to sustain electricity provision, for days or even weeks. 1 What they can provide is system flexibility—the ability to absorb and manage fluctuations in demand and supply by storing energy at times of surplus and releasing it when needed.

This document explores the definition of “long duration” as applied to energy storage. Given the growing use of this term, a uniform definition could aid in communication and consistency among various stakeholders. There is large and growing use of the Advanced Research Projects Agency–Energy (ARPA-E) definition of greater than 10 hours.
However, the term “long-duration energy storage” is often used as shorthand for storage with sufficient duration to provide firm capacity and support grid resource adequacy. The actual duration needed for this application varies significantly from as little as a few hours to potentially multiple days.
In a new paper published in Nature Energy, Sepulveda, Mallapragada, and colleagues from MIT and Princeton University offer a comprehensive cost and performance evaluation of the role of long-duration energy storage (LDES) technologies in transforming energy systems.
Some key observations include: Energy Storage Capacity: Sensible heat storage and high-temperature TES systems generally offer higher energy storage capacities compared to latent heat-based storage and thermochemical-based energy storage technologies.
Long-duration energy storage technologies can be a solution to the intermittency problem of wind and solar power but estimating technology costs remains a challenge. New research identifies cost targets for long-duration storage technologies to make them competitive against different firm low-carbon generation technologies.
The technology landscape may allow for a diverse range of storage applications based on land availability and duration need, which may be location dependent. These insights are valuable to guide the development of long-duration energy storage projects and inspire potential use cases for different long-duration energy storage technologies.

There are a number of pathways available for the future of electricity supply in Iraq but the most affordable, reliable and sustainable path requires cutting network losses by half at least, strengthening regional interconnections, putting captured gas to use in efficient power plants, and increasing the share of renewables in the mix.

Iraq's electricity generation primarily depends on fossil fuels. In 2021, natural gas was the largest source at 57.3% of the total, followed by oil at 36.7%. Renewable energy, mainly from hydroelectric power, contributed 5.9%. As of 2023, the 30 gigawatts (GW) of installed capacity cannot meet summer peak demand.
Nearly all (about 98%) of Iraq’s electricity generation is from oil and natural gas.62 Natural gas use in the electric power sector increased after 2016 because Iraq began importing natural gas from Iran to increase its own supplies. Hydroelectricity accounts for most of the remaining share of electricity production.63
