Project Overview
The Puertollano plant represents a landmark in industrial-scale green hydrogen production. Integrated directly with a 100 MW solar PV plant and a 20 MWh battery storage system, the 20 MW electrolyzer system requires sophisticated control strategies to manage the intermittency of solar power while meeting the steady demand of the adjacent fertilizer plant.
The Challenge
- 01High volatility of solar PV output requiring rapid electrolyzer response.
- 02Strict purity requirements for downstream ammonia production.
- 03Need to balance battery storage life with grid stabilization duties.
The Solution
An end-to-end digital control system that integrates weather forecasting, battery management, and electrolyzer control into a single unified platform. The system uses predictive analytics to pre-cool electrolyzers before production spikes and manages battery charging/discharging to smooth out solar ramps.
