![]() ![]() This produces a viscous gray substance that can be stored in cartridges. To complete the process of making the goo, metal salt and ester are added to the magnesium hydride. The result is a magnesium hydride substance. To make the paste, the researchers combined the hydrogen with magnesium at about 350✬ (662✯) and between five and six times atmospheric pressure. The pate holds the H2 in a chemical form at atmospheric pressure and is available when needed. Instead of compressing it as a gas, the energy is transported n the form of a magnesium hydride-based goo. ![]() The reduction and reuse of the by-products generated during the refinement of lithium is the focus of the institute’s work. The team at the Fraunhofer Institute for Manufacturing Technology and Advanced Materials (IFAM) in Dresden developed the new strategy for storing and transporting H2 fuel. The switch to electromobility will make Germany the central location for battery production in Europe and thus also for the production of the crucial precursor lithium hydroxide. The Powerpaste packs offer an entirely new way to store the hydrogen energy for vehicles. The high pressure required also makes it an impractical fuel storage option for smaller vehicles such as scooters or motorcycles. This is one of the benefits, hydrogen has over the current lithium battery, except that the extra weight added to the vehicle requires more fuel in order to power it. ![]() The downside of the tanks is that they are large, and they add quite a bit of weight to the vehicles, which works against one of the leading advantages of H2, which is its higher energy density. POWERPASTE is an ultra-high capacity hy- drogen storage substance for PEM fuel cell applications invented and developed by Fraunhofer IFAM. Traditional fuel cell vehicles store their H2 in tanks in tanks under pressure of about 700 bar (10,150 psi). Moreover, the refueling process takes only minutes. The Powerpaste packs make it possible for hydrogen fuel cell vehicles to boast a better range than gasoline powered vehicles. This presents a new option for fuel cell vehicles to be able to increase their range over gas-powered ones. Researchers at Fraunhofer have presented Powerpaste packs based on magnesium for the storage of clean hydrogen energy at density ten times greater than that of a lithium battery. Fraunhofer has patented their invention in the United States and EU.This gray goo provides a safe and simple form of storage for clean hydrogen energy. įraunhofer states that they are building a production plant slated to start production in 2021, which will produce 4 tons of Powerpaste annually. įraunhofer claims that Powerpaste is able to store hydrogen energy at 10 times the energy density of a lithium battery of a similar dimension and substantially more than compressed hydrogen at 700 bar and is safe and convenient for automotive situations. German Institute of Global and Area Studies (GIGA) (2019) Stable. Magnesium hydroxide (Mg(OH) 2) is a residue by-product created by this process. Lithium-Ion Battery Recycling Finally Takes Off in North America. The molecular formula of magnesium hydride reacting with water is MgH 2 + 2H 2O → 2H 2 + Mg(OH) 2, so half of the produced hydrogen comes from the Powerpaste and half from the water. When Powerpaste reacts with water it produces hydrogen in a predictable manner for use in fuel cells. An ester and a metal salt are then added to make the finished Powerpaste. Powerpaste is made by combining magnesium powder with hydrogen in a process conducted at 350 ☌ (662 ☏) and five to six times atmospheric pressure to form magnesium hydride. It was invented, patented and is being developed by Fraunhofer Institute for Manufacturing Technology and Advanced Materials (IFAM) of the Fraunhofer-Gesellschaft in Dresden, Germany. Powerpaste is a magnesium- and hydrogen-based fluid gel that releases hydrogen when it reacts with water. Gel that releases hydrogen when it reacts with water
