Picea smart home energy systems combine hydrogen storage with advanced digital controls to optimize residential energy use. The Picea app allows users to monitor real-time energy flows, adjust heating/cooling preferences, and set ventilation modes. Key functionalities include: - Dynamic load balancing: Automatically prioritizes solar power, hydrogen, or grid energy based on demand. - Predictive management: Anticipates energy needs during events (e.g., vacations, parties) and adjusts hydrogen reserves accordingly. - Emergency backup: Maintains power supply during grid outages via reserved hydrogen stores. By integrating with heat pumps and solar arrays, Picea enables households to achieve 100% renewable energy independence, reducing reliance on fossil fuels and mitigating energy price volatility.
