Tapping the Ocean’s Heat: Smarter Designs for Clean Power

Most renewable energy stories focus on wind and solar, but the oceans are an immense, underused source of power. Ocean Thermal Energy Conversion (OTEC) is a technology that captures the natural temperature difference between warm surface water and cold deep water to generate electricity. It’s a renewable supply that is predictable and constant — unlike … Continue reading Tapping the Ocean’s Heat: Smarter Designs for Clean Power

Sodium Batteries Take a Leap Towards the Grid

Lithium-ion batteries may dominate today’s clean energy storage, but they come with problems: they rely on scarce lithium and cobalt, and their costs are tied to volatile supply chains. That is why researchers have long looked to sodium — far more abundant and geographically widespread — as a promising alternative. Until now, however, sodium metal … Continue reading Sodium Batteries Take a Leap Towards the Grid
