MIT scientists develop CSP system to produce hydrogen

Massachusetts Institute of Technology (MIT) scientists have developed a train-like concentrated solar power (CSP) system for hydrogen production, with plans to build a prototype in the coming year. They say that this innovative system can capture up to 40% of the sun’s heat to produce environmentally friendly hydrogen fuel.

Solar power generation soars in Mexico, southwestern US

In a new weekly update for pv magazine, Solcast, a DNV company, reports that areas across Mexico and Southern Texas saw reduced cloud, leading to 120-130% of average September Irradiance. Meanwhile, storms and a ‘Bomb’ cyclone caused by persistent low pressure over British Columbia delivered cloudier conditions, leading to irradiance as low as 70% of long term averages.

Dutch startup optimizes Edison battery for industrial hydrogen production

Battolyser Systems has improved the efficiency of its Edison battery for industrial hydrogen production. The Dutch startup said the levelized cost of hydrogen (LCOH) could be cut to €1.50 ($1.58) per kilogram by 2025. It has partnered with the European Investment Bank to support its expansion, with ambitious plans to hit 1 GW of production capacity by 2026.
