🧃Battery Boom: The Quiet Revolution Powering the Future

Welcome to The Strawman, the daily climate newsletter that's quietly charged up over the weekend (we took full advantage of the slight sunshine we finally got in the UK)—like a battery, we’re ready to light up your inbox. Let's plug into today's topic.

Battery Boom: Powering Up the Future

Batteries are having a moment. On a five-acre patch of land in Hampshire, UK, a new battery installation just powered up, capable of supplying electricity to 44,000 homes for 24 hours straight. This isn’t just an energy flex—it’s a sign of how far battery tech has come. Since 2010, lithium-ion battery costs have dropped by over 90%, while energy density has surged. That means more power in less space, and developers are making the most of it.

Globally, battery deployment skyrocketed to 70 gigawatts in 2024, up from 43GW the year before. The International Energy Agency (IEA) predicts that by 2030, batteries will be adding more capacity to the grid than new fossil-fuel plants. It’s a quiet revolution that’s reshaping how we think about energy storage—making it possible to smooth out the unpredictable supply from wind and solar and keep the lights on when nature isn't playing ball.

Why Markets Need to Catch Up with Battery Tech

But there’s a catch: battery tech is speeding ahead, while energy market systems are stuck in the past. Think of it like trying to fit a Tesla into a parking spot designed for a horse and buggy.

Electricity markets were built for an era dominated by coal, gas, and hydropower—not for modern, flexible technologies like battery storage. And the cracks are showing. Batteries in many countries still pay network fees twice—once for charging and once for discharging—despite the fact they’re helping stabilise the grid. They’re also not always compensated for the crucial services they provide, like stepping in when the grid wobbles.

It’s not just a bureaucratic headache. Without the right incentives, investment in battery storage might lag, threatening the smooth integration of renewables. The IEA is calling for urgent reform, arguing that outdated pricing models risk leaving this critical sector underpowered.

The Double-Charge Dilemma: What’s Holding Back Batteries?

In some countries, batteries are already struggling to make financial sense. Developers argue that charging them twice for helping the grid is like charging firefighters for using water to put out a fire. And while construction costs for battery projects are rising (thanks, inflation <3), falling battery prices have so far kept projects on track. For example, a recent project in the UK came in 40% cheaper than one built just three years ago.

But the economics are still tight. Developers say clearer pricing structures and fairer fees are essential to unlocking the full potential of batteries. After all, these are the silent partners of the green revolution—absorbing excess energy when the wind’s howling and the sun’s blazing, then releasing it when the grid’s thirsty for power.

With the right support, battery storage could help power systems become 90-95% green. That’s not just a nice-to-have; it’s the backbone of a resilient, clean energy future.

The Strawman’s Takeaway 

Batteries might be the unsung heroes of the green transition, but outdated energy markets could hold them back. If we want a future where clean energy isn’t wasted, it’s time to give these silent giants the recognition—and compensation—they deserve.
