California is the sixth largest economy in the world. It also has a generous endowment of wind and sunshine. So it’s no wonder the Golden State plans to have 50% renewable energy by 2050. There is still a way to go ahead, but at least they are moving in the right direction. A direction others should follow. And batteries are key to this exciting goal.
How Batteries are Key to California’s Green Goal
Electricity utilities have one over-riding performance indicator, and that is availability, When we turn on a switch we want instant light and no excuses.
Batteries are key to the solution when the sun does not shine in California, or the wind is just a gentle breeze. Because they are the only way utilities can store surplus electricity for when they need it in peak demand.
The Battery Solution Has Been a While Coming
Until quite recently, utilities thought the only solution was to have energy in spinning reserve in spare units in power stations. Or rely on gas peaking stations.
Both were hugely expensive, but at least they could add them to the grid on the flick of a switch. California has a greener solution that is better for the health of the planet.
Batteries are key. California wants to have 1,325 megawatts of battery storage by 2020, and that’s just the beginning.
In a Flash, the Green Vision for the Future is Nearer
As battery technology evolves, California is building out towards a state where renewables and batteries dominate electricity grids. The only things holding solar energy back are vision, resolve, and battery capacity but this is changing. In Tasmania, a group of residents already share the load.
Lithium-ion costs are coming down; zinc is looking good, while hydrogen storage and molten salt are waiting in the wings. There is also talk of lead-acid commanding center stage. A few years ago. battery storage was a ‘yes … but’. Now batteries are key to California’s renewable energy future. Cam we have some more, please
