New technologies and designs aimed at driving down the cost of energy storage facilities are currently the focus of intense industry R&D. Sara Verbruggen reports on DC coupling, an emerging system architecture that many believe will soon become the industry standard.

DC-coupling of combined solar and energy storage plants could be a more effective way to save energy that would otherwise be clipped and ‘lost’, benefitting the grid and helping efforts to reduce the amount of carbon pumped into the air, the COO of Fluence has said.
