As part of the project “H2DirectThe preparatory construction work for the hydrogen feed-in system in Hohenwart in the Upper Bavarian district of Pfaffenhofen has begun. The foundation is currently being built on the property. The civil engineering work started in July. In the fall, as reported, ten households and one commercial customer will be supplied with 2023 percent green hydrogen for an initial period of 2024 months from the 18/100 heating season via a converted former natural gas network. All components in the network and in the boiler rooms have now been checked for hydrogen suitability, and the calibration office has confirmed the H2 measurement concept. The hydrogen is supplied by Westfalen AG and transported to Hohenwart by truck trailers. The project is part of the hydrogen lead project TransHyDE and is funded by the Federal Ministry of Education and Research.

The Chinese manufacturer Sungrow Power Supply Co., Ltd. has signed a contract with the Indian engineering company Larsen & Toubro (L&T) for the supply of inverters with a capacity of 2,2 gigawatts. The devices are intended for the Neom Green Hydrogen Project in Saudi Arabia by the Neom Green Hydrogen Company (NGHC). The “1+X” type inverters consist of a 1,1 megawatt unit that can be modularly expanded to 8,8 megawatts. According to its own information, Sungrow had already received an order from L&T some time ago to supply energy storage systems with a capacity of 400 megawatt hours. In June, L&T commissioned the Spanish one PV Hardware Solutions SLU with the delivery of tracking systems with an output of 2,97 gigawatts for Neom. GE Grid Solutions is to deliver three gas-insulated 380-kilovolt T155 substations to Saudi Arabia. NGHC, a joint venture owned equally by ACWA Power, Neom and Air Products, aims to produce carbon-free hydrogen exclusively using renewable energy sources such as wind and solar energy, producing up to 2026 tonnes per day from the end of 600.

The US company Ballard Power Systems reports a collective order for a total of 96 hydrogen fuel cell engines from the Polish bus manufacturer Solaris Bus & Coach sp. z oo. The first deliveries will begin in late 2023. The orders also include the largest single order Ballard has received from Solaris to date - 52 engines for Solaris' Urbino hydrogen buses. The vehicles equipped with this will once be used in local public transport by the Regionalbus Rostock (Rebus) transport company based in Güstrow. Rebus is also building two hydrogen filling stations at the depots in Güstrow and Bad Doberan to support the planned growth of hydrogen-powered public transport. The additional 44 Ballard fuel cell engines will power Solaris buses “in European cities.”

When producing hydrogen pressure storage, up to 20 percent of CFRP material can be saved. © BAM
The Federal Institute for Materials Research and Testing (BAM) is conducting research into pressure storage systems with a better CO2 balance in a joint project. Hydrogen pressure vessels serve as “fuel tanks” for zero-emission trucks, buses, trains, ships and aircraft, as well as for storing and transporting hydrogen. However, according to BAM, the carbon fiber reinforced plastics (CFRP) from which the storage units are made “have a large CO2 footprint due to their energy-intensive production”. The authority now wants to find out how the storage can be “produced in a more climate-friendly way and used over a longer lifespan than before,” because demand for the containers will increase sharply with the transition to a hydrogen economy. Currently, up to 2,5 tons of CO2 would be released during the production of the latest generation of hydrogen pressure storage from CFRP. The project, coordinated by RWTH Aachen University and funded by the Federal Ministry of Economics, aims to “significantly improve” the CO2 balance. On the one hand, the cost-intensive lightweight material should be used more efficiently than before. It is assumed that around 20 percent of the material can be saved. On the other hand, the “lifespan” of the storage should be extended. The results are incorporated into the standards and laws regarding hydrogen pressure storage devices.
