Compact Medium-Voltage Converters To Enable Advanced Grid Architectures & Operations

As we trend toward more renewables and distributed energy resources (DERs), the design of the electric distribution system itself imposes physical limitations. These system constraints could lead to issues like overloaded power lines and faults that propagate freely. But what if we could restructure the underlying system to support greater … [continued]

Calendar Aging Research Is Critical to Future of Silicon-Based Batteries

In the race against climate change, state-of-the-art energy storage solutions are paramount to leveraging power generation from clean energy sources, and National Renewable Energy Laboratory (NREL) researchers are exploring strategies to increase battery cell energy density while decreasing manufacturing costs. Silicon anodes offer a promising improvement to existing lithium-ion (Li-ion) … [continued]

Analysis: Electric Heavy-Duty Vehicle Powertrains Can Provide Lower Total Cost of Ownership

For commercial medium- and heavy-duty electric vehicles, the adoption of a new technology relies heavily on its cost relative to alternatives. A new report from the National Renewable Energy Laboratory (NREL) seeks to pinpoint the conditions for when battery electric or fuel cell electric commercial trucks offer economic advantages over … [continued]
