A step forward in the direct electrolysis of sea water
February 1, 2023
Unfortunately, the electrolysers on the market require fresh water which is rather scarce considering the traditional needs which are primary. On the contrary, sea water is available in practically inexhaustible quantities and therefore could be the solution. The first alternative consists in desalination of sea water in order to be able to use the electrolysers already available. The alternative is the construction of new electrolysers that are able to use sea water directly.

Successful maiden flight of the Dornier 228 ZeroAvia
January 19, 2023
The maiden flight of the 19-seat Dornier 228, equipped with a full-size prototype hydrogen-electric propulsion unit on the left wing of the aircraft, took place successfully. The 10-minute flight is part of the HyFlyer II project which aims to develop a 600 kW powerplant for 9-19 seat zero-emission aircraft.
A new semiconductor for the photolysis of water
January 5, 2023
Researchers at the University of Michigan have developed a new type of solar panel for photolytic splitting of water achieving an efficiency of 9%. The study was published on Nature: Solar-to-hydrogen efficiency of more than 9% in photo-catalytic water splitting (DOI: 10.1038/s41586-022-05399-1).
This result was achieved using a catalyst formed by nanostructures of indium and gallium nitride, grown on a silicon surface. This made it possible to obtain a semiconductor capable of withstanding a concentration factor of 160 suns. This concentration of sunlight, obtained by means of a special large lens, allows to reduce the size of the expensive semiconductor.

Equinor and RWE coopertaion
January 5, 2023
Equinor and RWE have signed a memorandum of understanding to work together to replace German coal-fired power plants with natural gas-fired power plants already ready for hydrogen. In fact, the agreement also provides for the construction in Norway of an infrastructure for the production of low-carbon hydrogen which will be exported via gas pipeline to Germany.

First green hydrogen-natural gas blend distribution operation in India
January 3, 2023
NTPC Ltd and Gujarat Gas Limited (GGL) have started India's first green hydrogen and natural gas blending project. The blend is destined for the town of Kawas, Surat. The electricity for the production of green hydrogen by electrolysis of water is supplied by an existing floating solar plant with a power of 1 MW.

H2A-Lite from NREL
December 29, 2022
Hydrogen can be produced using different resources and different technologies. The processes can be thermochemical, electrochemical or biological and are characterized by different Technology Readiness Levels. As the demand for hydrogen is expected to increase significantly in the coming decades, it becomes very important to analyse the environmental and economic performance of different production options.
Indian plans for green hydrogen industry
December 27, 2022
Indian industry uses 5 million tonnes of grey hydrogen a year, the cost of which has recently risen to around 200 rupees. Although the cost of green hydrogen is not yet competitive, many countries are starting to incentivize its production.
