How long-duration energy storage is powering a renewable future
As the world races to install more renewable energy, one question lingers in the background: what happens when the sun isn't shining or the wind isn't blowing? In 2024, global renewable capacity additions hit a record 740 gigawatts, with solar power leading the charge. But while generation is booming, energy systems are still grappling with how to store that power reliably—and at scale. The answer, increasingly, lies in long-duration energy storage (LDES) technologies that go far beyond lithium-ion. From molten salt to compressed air to next-gen thermal systems, LDES is reshaping the way we think about renewable power. These systems aren't just topping up the grid for a few hours; they're designed to store clean energy for 10, 20, or even 100 hours, stabilising supply through nights, storms, and seasonal changes. One of the most promising examples is Exowatt's P3 system—a compact modular unit that captures solar heat and stores it thermally for round-the-clock power delivery. Designed with high-consumption clients like data centers and industrial zones in mind, P3 can deliver dispatchable renewable energy for up to 24 hours, with zero combustion and minimal land use. Other solutions, like Quidnet's Geomechanical Pumped Storage, store pressure underground and return it as electricity months later—acting like a natural battery embedded in rock. While still in early deployment, these technologies are beginning to show that the renewable future isn't just about production—but predictable availability. In Oman, where sunlight is abundant and energy demand peaks during hot evenings, long-duration storage is emerging as a natural extension of the country's clean energy ambitions. Alongside its expanding portfolio of solar and green hydrogen projects, Oman is preparing for its first utility-scale storage initiatives. Local firms like ONEIC and Takhzeen are advancing innovative technologies, including CO2-based energy storage, to enhance grid flexibility and accelerate decarbonisation. These early moves suggest that Oman is beginning to align renewable generation with the systems needed to deliver it—reliably, efficiently, and around the clock. Long-duration storage also offers strong potential synergy with Oman's emerging hydrogen economy. Excess solar power can be stored—or diverted into hydrogen production—during low-demand periods, creating a feedback loop between power and fuel that supports both resilience and export potential. Globally, investment in LDES is expected to surpass $50 billion by 2030, and pilot programs are already showing cost competitiveness, especially as lithium-ion supply chains face pressure. As systems mature and deployment grows, these technologies could redefine energy security—not just as a matter of fuel supply, but as a function of time. The sun doesn't always shine. But with long-duration energy storage, the power it provides doesn't have to set with it.

Quidnet Completes Testing of Long-Duration Geomechanical Energy Storage
Energy storage solutions group Quidnet Energy said the company has successfully completed demonstration and testing of its Geomechanical Energy Storage (GES) technology at a megawatt-hour (MWh) scale. Quidnet, headquartered in Houston, Texas, on Feb. 26 said tests confirm that its GES solution can deliver grid-scale energy storage. The company conducted MWh-scale functional testing and accelerated lifetime testing of the GES technology at its test site in the Houston area. Company officials said that in addition to proving the viability of its technology at grid-scale, Quidnet's results validated the capabilities of the GES technology across critical performance benchmarks, including negligible self-discharge and capacity degradation. These metrics provide real-world validation of GES as a long-life asset for supporting grid stability and delivering reliable power. 'Achieving this level of performance and scale marks a major milestone in our development of the GES technology,' said Joe Zhou, CEO of Quidnet Energy. 'These tests confirm that our storage technology is ready for commercial deployments just as electrical grids grapple with the rapid rise in load growth from industrial electrification and AI data centers. With a mature, well-established supply chain and proven technology, we look forward to delivering GES at scale at a critical time for the energy industry.' According to Quidnet, the GES technology 'stores energy as high-pressure water underground to meet the demand for reliable power. The entire module is built on conventional drilling technology and mature hydropower technology. Facilities operate with closed-loop water systems, designed for conservation against evaporative loss. The energy-storing rock bodies found abundantly throughout the world, intersecting with major electricity transmission and distribution hubs.' Quidnet said the MWh field test in Texas highlights the market potential for providing reliable power in its home state, which has struggled with power supply issues in recent years. Texas also is expected to experience some of the largest increases in electricity demand in the coming years, including from the growth in energy-intensive data centers. The state's power problems also have underscored the need to prepare for weather-related grid events by developing more reliable and stable power resources. These tests of the GES technology also mark a milestone in Quidnet's developmental support from Dallas-based Hunt Energy Network after that Hunt's $10-million investment announced last year. 'With the completion of these tests, we are excited to see Quidnet demonstrate the viability of their GES technology at MWh scale and further establish confidence for the durability of this storage solution,' said Pat Wood, CEO of Hunt Energy Network. 'As Quidnet prepares for commercial projects, we look forward to collaborating with the company on our 300 MW partnership for storage in Texas.' —Darrell Proctor is a senior editor for POWER.
