Scientists from Switzerland intend to use solar-charged metal balls to produce hydrogen and heat. Up to fifty times more energy can be stored in aluminum than in lithium-ion batteries. This makes it a promising form of energy storage, especially in regions where winter solar is scarce. The great difficulty of renewable energy has been extensively discussed in the past: the sun and the wind are not consistent energy sources. Consequently, the search for efficient energy storage solutions is ongoing. This allows us to retain excess solar and wind energy until night, cloudy, or windless conditions occur. No sunlight in winter…

If CAF and Talgo are running practically in parallel in the race to put green hydrogen-powered trains into service, France’s Alstom is a good handful of steps ahead. The French giant, owner of the Bombardier plant in Trapagaran, has just inaugurated the first hydrogen-powered passenger railway line in Germany and continues to show off its merits against its competitors with a view to the desired landing in Spain. The managers of the French railway company have already made it clear on several occasions that they are firmly committed to place hydrogen trains in the Spanish market, a top priority just…
