    Frankfurt, Germany (SPX) Sep 09, 2019 Global investment in new renewable energy capacity this decade - 2010 to 2019 inclusive - is on course to hit USD 2.6 trillion, with more gigawatts of solar power capacity installed than any other generation technology, according to new figures just published. According to the Global Trends in Renewable Energy Investment 2019 report, released ahead of the UN Global Climate Action Summit, t […]

  • Ammonia for fuel cells
    on September 17, 2019 at 12:30 pm

    Newark DE (SPX) Aug 23, 2019 Fuel cells are pollution-free power sources that convert chemical energy to electricity with high efficiency and zero emissions. Fuel cell cars, trucks, and buses would allow people to travel long distances with convenient refueling and less of a carbon footprint. Researchers at the University of Delaware are working on technology to make fuel cells cheaper and more powerful so that fuel c […]

  • Silicon carbide more efficient as a semiconductor
    on September 17, 2019 at 12:30 pm

    Basel, Switzerland (SPX) Sep 09, 2019 In power electronics, semiconductors are based on the element silicon - but the energy efficiency of silicon carbide would be much higher. Physicists of the University of Basel, the Paul Scherrer Institute and ABB explain what exactly is preventing the use of this combination of silicon and carbon in the scientific journal Applied Physics Letters. Energy consumption is growing across the g […]

  • Coating developed by Stanford researchers brings lithium metal battery closer to reality
    on September 17, 2019 at 12:30 pm

    Stanford CA (SPX) Aug 27, 2019 Hope has been restored for the rechargeable lithium metal battery - a potential battery powerhouse relegated for decades to the laboratory by its short life expectancy and occasional fiery demise while its rechargeable sibling, the lithium-ion battery, now rakes in more than $30 billion a year. A new coating could make lightweight lithium metal batteries safe and long lasting, a boon for d […]

  • Renewable energy surges as power emissions keep rising: UN
