Google-backed Energy Dome to launch long-duration CO₂ battery project in Oman
Partnership with Takhzeen Oman, in alignment with Vision 2040, aims to boost renewable energy integration
MUSCAT, Oman (MNTV) — Google’s recent global partnership with Italy-based energy storage firm Energy Dome is set to accelerate Oman’s clean energy transition, as the company’s local partner, Takhzeen Oman, prepares to deploy the country’s first large-scale long-duration storage system.
Energy Dome has pioneered an innovative long-duration energy storage (LDES) technology using carbon dioxide (CO₂) as the working fluid, reported Zawya news.
The partnership with Google—announced last month through an equity investment by Alphabet Inc’s search engine division—is being hailed as a significant milestone for the future of renewable energy integration globally and within the Gulf region.
In Oman, Energy Dome’s technology is being introduced through Takhzeen Oman, a company established as part of a broader collaboration initiated by a Memorandum of Understanding (MoU) between Energy Dome and Oman Investment Authority (OIA).
The OIA, through its venture capital arm IDO Investments, was among the early backers of Energy Dome’s international funding round three years ago.
Takhzeen Oman’s Managing Director, Eng. Nawaf al Balushi, said the new partnership with Google validates the promise of Energy Dome’s CO₂ Battery, which he described as a “breakthrough” in scalable and cost-effective energy storage.
“As Energy Dome’s local technology partner, Takhzeen Oman views this as a powerful endorsement of long-duration storage,” said Al Balushi. “This collaboration aligns with Oman Vision 2040 and demonstrates the vital role of innovative, localized solutions in advancing national sustainability goals.”
According to Al Balushi, the upcoming project will integrate solar energy with CO₂ battery storage in a hybrid design.
Solar-generated electricity will charge the battery during daylight hours, while stored energy will be discharged at night or during peak grid demand periods. This configuration will support both energy reliability and price efficiency.
Under the terms of the agreement, Energy Dome will supply the complete battery storage infrastructure, while Takhzeen Oman will manage installation, operation, and ownership of the facility for a 30-year period.
The clean electricity produced will be sold to an offtaker under a long-term power purchase agreement.
The project marks a significant step toward meeting Oman’s rising energy needs through sustainable technologies and complements the country’s broader clean energy agenda under Vision 2040.
Energy Dome officials, who visited Muscat earlier this year, emphasized that their partnership with Takhzeen Oman will be central to regional rollout plans for long-duration energy storage technologies.
