The quest for sustainable energy solutions has led to a groundbreaking development in the field of electrocatalysis. Oxylus Energy, a pioneering company based in New Haven, Connecticut, has recently made headlines with its innovative technology that converts carbon dioxide (CO2) into methanol at room temperature and pressure. This article delves into the details of this technology, offering a comprehensive explanation of its significance and potential impact on the industry.
The Electrolysis Cell: A Glimpse into the Future
Oxylus Energy’s unveiling of a 5-cm² electrolysis cell marks a significant milestone in electrochemical research. The cell demonstrates an electrified CO2-conversion process that operates under ambient conditions, which is a first in the realm of commercially viable reactor designs. The key to this technology lies in the special modifications made to the cobalt phthalocyanine catalyst, a breakthrough achieved by Professor Hailiang Wang and Oxylus’s Chief Technology Officer, Conor Rooney, at Yale University’s Energy Science Institute.
The Catalyst: Cobalt Phthalocyanine’s Role
The cobalt phthalocyanine catalyst, when spread over carbon nanotubes and combined with a microporous layer added to the catalytic electrode structure, exhibits remarkable methanol selectivity. This selectivity has been enhanced from an initial 40% to over 80%, thanks to the microporous layer’s ability to improve mass transport of CO and increase the Faradaic efficiency.
Commercial Viability: The Road Ahead
Oxylus Energy is not stopping at the 5-cm² cell. The company is already testing a 50-cm² cell, with plans to scale up to production-level cells. This scalability is crucial for industries like aviation and petrochemicals that are in dire need of clean, renewable solutions.
