Military enthusiasm for energy storage applications is at an all-time high, according to one supplier close to the industry.

“There’s no doubt that their interest is strong,” said Ryan O’Keefe, senior vice president of business development at the power conversion systems maker Ideal Power.

Energy storage is seen as one of a number of technologies that can help military chiefs offset costs and risks while allowing troops to operate more independently in the battlefield, he said.

“They identified quite some time ago that their military bases, wherever they are, are at the mercy of the electric grid. The military is clearly in planning mode for how to make their operations resilient.”

Ideal Power is currently working with “a couple” of military suppliers on how to improve frontline logistics and power quality.

Could the grid stymie India’s storage plans?

Doubts over the strength of the grid have called into question a USD$17.2bn plan to build 10GW of pumped hydro storage in India.

Central Electricity Authority chairman SD Dubey unveiled the five-to-six-year pumped hydro programme last month.

The administration would be adopting pumped hydro to store excess power from India’s growing renewable energy sector because the storage medium is cheaper than batteries, he said.

But being able to store energy in pumped hydro reserves depends upon getting it to the dams in the first place.

And observers have questioned whether India’s grid is up to the task, particularly since it is already groaning under the impact of solar energy.
