World’s First Dual-Tower Solar Plant Boosts Efficiency by 24%

Material & Energy, Tech / Jorge Paka

In China’s Gansu Province, engineers have erected two towers standing at 650 feet (200 meters) tall. Alongside them, an array of 30,000 mirrors arranged in concentric circles will generate more than 1.8 billion kilowatt-hours of electricity annually. While photovoltaic panels, which directly convert sunlight into electricity, commonly associate with “solar power,” another method has been

The Most Efficient Hydrogen System in the World Scales up for Mass Production

Material & Energy, Tech / Leandro Conceição

Hysata guarantees the world’s most affordable hydrogen with a groundbreaking device that splits water into H2 and O2 at 95% efficiency, which is about 20% more efficient than the top conventional electrolyzers. The company has secured US$111 million to expand production.

Hydrogen production typically wastes 20-30% of renewable energy, contributing to high costs. Australian company Hysata’s capillary-fed electrolyzer offers 95% efficiency, using only 41.5 kWh of energy to create a kilogram of hydrogen. This reduces operational costs for hydrogen producers and CAPEX, making it the cheapest green hydrogen available.
