Energy storage is ready to become a key pillar of the US energy transition, writes Andy Tang of Wärtsilä Energy.

It’s been a rollercoaster couple of weeks for US clean energy, an industry accustomed to ups and downs in policy and market dynamics.

Tax incentives for energy storage included in the US’ Inflation Reduction Act could mean fewer solar-plus-storage hybrid plants are built.

The Inflation Reduction Act took a significant step forward over the weekend as US vice-president Kamala Harris cast a decisive vote.

Hopes have been raised once again that US lawmakers could introduce an investment tax credit for energy storage.

Andy Tang, VP of energy storage & optimisation for global energy technology group Wärtsilä, discusses software, supply chain, non-lithium storage technologies and more in this exclusive interview.

Actions taken this month by the US government to support solar industry unlikely to come at the expense of support for energy storage.

Solar and energy storage were described by Elon Musk as going together “like peanut butter and jelly”. Andy Colthorpe meets some of the players creating this winning combination in the US.

Battery energy storage is load shifting up to 6GWh a day on the California ISO (CAISO) grid, storage sector manager Gabe Murtaugh told Energy-storage.news, as the operator considers a market design change linked to batteries’ state of charge (SoC).

From 10GW of battery storage expected to be deployed in the US over the next two years, more than 60% will be installed with solar PV.
