Future climate policy assigns hydrogen and H2 synthesis products great importance. But how could the demand for hydrogen develop globally? A new meta-study coordinated by Fraunhofer ISI addresses this question and re-evaluates more than 40 energy system and hydrogen scenarios within the HyPat ...
Researchers Discover a Single Catalyst Capable of Splitting Both Freshwater and Seawater at Low Voltage
Hydrogen has drawn attention in recent years as a potential source of clean energy because it burns without producing climate-damaging emissions. However, traditional hydrogen production methods have a substantial carbon footprint, and cleaner methods are expensive and technically complex. Now ...
A breakthrough for green hydrogen is not a given – decisive policy action is required
Green hydrogen from renewable electricity and derived e-fuels are uniquely valuable for achieving climate neutrality. They can replace fossil fuels in industry or long-distance transport where direct electrification is infeasible. However, even if production capacities grow as fast as wind and ...
High-efficiency utilization of CO2 facilitates the reduction of CO2 concentration in the global atmosphere and hence the alleviation of the greenhouse effect. The chemical utilization of CO2, which refers to converting CO2 into value-added chemicals and liquid fuels, has a distinct and direct CO2 ...
In a first, a dye-sensitized photocatalyst that facilitates the most efficient solar water splitting activity recorded to date (for similar catalysts) has been optimized by researchers from Tokyo Tech. Their surface-modified, dye-sensitized nanosheet catalyst shows immense potential, as it can ...
A new design for solid-state hydrogen storage could significantly reduce charging times
Researchers from the University of Technology Sydney (UTS) and Queensland University of Technology (QUT) have developed a new method to improve solid-state hydrogen fuel cell charging times. Hydrogen is gaining significant attention as an efficient way to store 'green energy' from renewables such ...
Chemically induced nanostructures
Electrical energy from wind or sun can be stored as chemical energy in hydrogen, an excellent fuel and energy carrier. The prerequisite for this, however, is efficient electrolysis of water with inexpensive catalysts. For the oxygen evolution reaction at the anode, nanostructured nickel silicide ...
Energy in Iron and its Oxides
Transporting green-generated energy in form of iron: That is the vision of a project funded by the German Federal Ministry of Education and Research and coordinated by UDE. Hydrogen produced by solar energy, a chemical reaction and transport in metal form lead to a sustainable cycle to produce ...
Green hydrogen is to be used as an emission-free energy carrier on a large scale as soon as possible. Before this happens, materials and components, e.g. for fittings, seals, distribution networks and hydrogen filling stations, must be carefully tested for their suitability and safety. The ...
Recycled metal alloys allow circular economy for solid-state hydrogen storage
Not only the production of green hydrogen, but also its safe and compact storage is a major challenge for the energy transition. Metal hydrides could be a good solution - they can store large quantities of hydrogen in a small space. However, the mining and production of the up to now required ...
