Energy Storage Is Killing the Coal Power Fantasy — And the Numbers Prove It | Taha Abbasi

Despite political rhetoric about reviving coal, the economics of energy storage have rendered the coal power fantasy obsolete. Taha Abbasi, who tracks the intersection of energy technology and real-world deployment, breaks down why new storage solutions are making coal’s comeback mathematically impossible.

The Storage Revolution Is Here

Companies like Hydrostor are deploying advanced compressed air energy storage (A-CAES) facilities that can provide long-duration grid storage at costs that undercut coal generation. Combined with the explosive growth of lithium-ion battery installations — led by Tesla’s Megapack — the grid storage market has reached a tipping point where new renewable-plus-storage installations are cheaper than maintaining existing coal plants, let alone building new ones.

Taha Abbasi emphasizes that this is not a future projection. It is current market reality. The levelized cost of energy (LCOE) for solar-plus-storage has dropped below $40 per megawatt-hour in many regions, while coal generation typically costs $65-150 per MWh when including externalities and maintenance.

Why Duration Matters

The historic criticism of renewable energy — that the sun does not always shine and the wind does not always blow — is being systematically dismantled by long-duration storage technologies. While lithium-ion batteries excel at 2-4 hour discharge cycles, technologies like compressed air, iron-air batteries, and flow batteries can store energy for 8-24 hours or more.

This eliminates coal’s last remaining value proposition: baseload reliability. When you can store solar energy generated at noon and discharge it at midnight, the need for always-on coal generation evaporates. The economics follow the physics.

Tesla Megapack Leading the Charge

Tesla’s Megapack division has become one of the most quietly transformative businesses in the company’s portfolio. Demand for grid-scale battery storage has been so strong that Tesla cannot build Megapacks fast enough to meet orders. The company’s dedicated Megapack factory in Lathrop, California produces units that are shipped globally.

Each Megapack provides 3.9 MWh of storage capacity. Deployed in arrays of hundreds of units, they create virtual power plants that can replace peaker plants — the dirtiest and most expensive generators on the grid. Taha Abbasi sees Tesla’s energy division as potentially more valuable than its automotive business within a decade.

The Political Disconnect

The irony of pro-coal political positioning is that market forces are rendering the debate moot. Utilities — including those in coal-heavy states — are choosing renewable-plus-storage installations because they are simply cheaper. No amount of regulatory support for coal can overcome the basic economics when batteries continue to drop in cost by 10-15% annually.

As Taha Abbasi often notes, the energy transition is not primarily a political issue. It is an economic inevitability. Companies and regions that recognize this early will benefit; those that fight it will pay the price in stranded assets and higher consumer electricity costs.

What Comes Next

The next frontier in energy storage is vehicle-to-grid (V2G) technology, where millions of parked EVs collectively function as a distributed battery network. Tesla’s Cybertruck already supports bidirectional charging, effectively turning each vehicle into a mobile Powerwall. When multiplied across millions of vehicles, this represents a storage capacity that dwarfs anything currently deployed on the grid.

The coal fantasy is just that — a fantasy. The future is being built with batteries, solar panels, and software. And as Taha Abbasi continues to document, that future is arriving faster than anyone predicted.
