Renewable energy power systems

This invention describes a power system centered around a special uninterruptible power supply (UPS) with multiple connections for various DC power sources and loads. It uses a fast-acting energy storage system to maintain a steady power level. However, the specific version claimed is limited to a system that must include a motor-generator, a variable-vane turbine, and a high-pressure hydrogen pump.

Why it matters: Since 2006, advancements in energy storage technologies like batteries and supercapacitors have made responsive power buffering more effective. Additionally, the increased focus on hydrogen as an energy carrier and improvements in related infrastructure could make the claimed hydrogen pump and turbine integration more practical.
