Cover Story: Solar energy offers an alternative for powering electrolysis for green hydrogen production as well as wastewater treatment. High costs and logistical challenges of electrolysis have limited widespread investigation and implementation of electrochemistry in wastewater plants. To overcome these challenges, researchers from the University of Western Ontario have designed and tested a new approach to chemical experiments and wastewater treatment tests, using a portable stand-alone open-source PV-powered station that can be located onsite with unreliable electrical power. Equipped with six wheels, 1.2 kW of solar panels, an energy-monitoring data acquisition system and sensors to enable real-time monitoring of gases, the unique setup demonstrates its potential and adaptability to different applications and scenarios.
