Science Never Sleeps, Green Hydrogen & Biochar Edition

Hydrogen is the grease that turns the wheels of the modern industrial economy, but it has a supply chain problem. Almost all of the global hydrogen supply comes from natural gas or gassified coal. That is slowly beginning to change as more sustainable “green hydrogen” sources emerge. In an interesting twist, biochar could be in play.

Sure enough, earlier this week the University of Illinois – Chicago reported the results of a study published in the journalThe short version, as condensed by the school’s media office, is that the research team reduced the energy needed to run the process by 600%. In a press statement, study co-author Rohit Chauhan explained that the process is “very efficient, with almost 35% conversion of the biochar and solar energy into hydrogen.”“We are the first group to show that you can produce hydrogen utilizing biomass at a fraction of a volt,” affirmed UIC associate professor Meenesh Singh, who led the multi-institutional study.

The idea would be to produce green hydrogen at night, when electricity demand is lower but wind speeds are optimal. The hydrogen could be stored for use in a fuel cell, deployed to produce green fertilizer, or sold as a revenue stream.and noted that the smaller and larger ends of the wind turbine scale have sparked the most activity, with relatively little interest in mid-sized turbines.
