Good morning! Cleantech entrepreneurs have been trying for years to reinvent pumped hydro storage and to harness the sea to produce energy. Sizeable Energy tells Julian Spector it’s found a way to do both — with help from giant, inflatable donuts it plans to deploy off the coast.

 

Xcel Energy is meanwhile taking a more traditional approach to energy storage. It’s seeking permission to double the planned capacity of a battery installation at its massive, under-construction Sherco solar facility, Brian Martucci reports.

 

Next, I wrap up our election coverage with a look at the clean energy challenges facing Virginia’s new Democratic trifecta. And Maria Gallucci recaps a panel she moderated with Microsoft and Google energy and data center leaders, where they shared how clean power sources and load flexibility will help them meet new demand.

POLITICS

  • An analysis of U.S. Democratic politicians’ social media posts, speeches, and podcast appearances shows they’re mentioning climate change far less in the years since the Inflation Reduction Act’s passage, and instead emphasizing energy affordability. (Washington Post)
  • The pipeline approvals reflect a political shift, as the traditionally blue Northeast softens its stance on fossil fuels in the face of federal pressure and soaring energy prices, analysts say. (E&E News)

GRID

  • The Southwest Power Pool plans an $8.6 billion slate of 50 transmission projects across its 14-state footprint that the grid operator says will help meet peak demand over the next decade. (Utility Dive)

DATA CENTERS

  • The U.S. data center boom could increase carbon emissions by the equivalent of adding 5 million to 10 million cars to the road each year, as well as significantly stress water supplies, according to new research from Cornell University. (E&E News)

NUCLEAR

  • California regulators hold off on approving Pacific Gas & Electric’s plan to continue operating its Diablo Canyon nuclear plant, saying the utility must first dedicate thousands of acres of land to conservation to mitigate its cooling system’s impacts on the ocean. (Tribune, E&E News) 

HYDROPOWER

  • Indigenous advocates and officials push back on U.S. Energy Secretary Chris Wright’s bid to revoke a 2024 federal policy giving tribal nations veto power over proposed hydropower projects on their land. (E&E News)
