A Deeper Look at Hidden Damage: Nano-CT Imaging Maps Internal Battery Degradation

The minerals that power lithium-ion batteries—including lithium, nickel, cobalt, manganese, and graphite—are both highly valuable and difficult to come by. As battery storage capacity across the United States continues to grow, constraints on the mining, refining, and processing of key minerals leaves our energy systems vulnerable to the fluctuations of … [continued]

Powering Data: NREL Partner Forum Puts Everything on the Table

NREL Announces Chip-to-Grid Consortium, Invites Collab Around Energy-Data Integration Over the past decade, energy demand from U.S. data centers has tripled—doubling in just the last two years. And the growth is not slowing down. Utilities are wondering where to add generation. Meanwhile, companies queue for that power. Governments are deciding … [continued]

Artificial Intelligence Models Improve Efficiency of Battery Diagnostics

NREL-Developed Neural Networks Uncover New Insights Into Battery Health Resilient energy systems depend on reliable batteries. The lithium-ion (Li-ion) batteries powering our world must endure the steady strain of time, charge cycles, and environmental conditions that gradually wear them out through degradation. Understanding the health of a battery can help … [continued]

Updated Risk Management Framework Supports Success of Marine Energy Devices

The life of a wave energy converter (WEC) may sound idyllic—bobbing on ocean waves all day or swaying underwater, quietly generating electricity for the people living and working near shore. But in reality, it takes a lot of careful planning for salt water and electronics to achieve that perceived state … [continued]

HERO’s Mission: An Elevator Part Could Bolster Marine Energy Technologies

Latest HERO WEC Mission Status Update Examines How a Polyurethane Belt Could Improve Reliability of Wave Energy Converters The National Renewable Energy Laboratory’s (NREL’s) wave-powered desalination research is charting new waters by improving the robustness, reliability, and deployability of the hydraulic and electric reverse osmosis wave energy converter—or HERO WEC. To do this, … [continued]
