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

Material & Energy, Tech /

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 /

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.

New Method Cuts Costs by 30% in Converting CO2 to High-Value Chemicals

Material & Energy, Tech /

NUS researchers, led by Assistant Professor Lum Yanwei, have developed a groundbreaking technique to address rising CO2 emissions and their impact on climate change. Their method greatly improves the conversion of waste CO2 into valuable chemicals and fuels, directly from treated industrial flue gas. This innovation turns CO2 into key raw materials like ethylene and ethanol, vital for everyday products such as plastics and detergents, offering a sustainable method to repurpose waste and reduce reliance on fossil fuels.

By circumventing the need for high-purity CO2, the NUS research marks a substantial advancement in addressing the carbon cycle. This breakthrough not only helps reduce CO2 emissions but also advances carbon utilization. By turning waste CO2 into valuable resources, the research supports global efforts to combat climate change and promote sustainability.
