Norwegian consultancy Rystad Energy says that hydrogen pipelines will be “much better” than ships for transporting hydrogen over short and medium distances in the coming years.
Dominion Energy Utah (DEU) is launched hydrogen blending in Delta, Utah as part of an ongoing project. It said it tested the 5 percent hydrogen blend for nearly a year and found that “the hydrogen was safe, compatible with current home appliances, and helped reduce emissions from appliances that already use clean-burning natural gas.” The second stage consists of a maximum of 5% mixing. It is presented in the city and several nearby cities, serving a total of approximately 1,800 customers.
Ingeteam has developed a new rectifier for electrolyser power based on insulated gate bipolar transistor (IGBT) technology. The new product is designed for large green hydrogen production plants. The company announced that it will deliver the first units in September to projects in Germany and Spain.
H-TEC Systems has developed a modular hydrogen electrolyser for large projects over 10 MW. German company said it can connect 10 MW modular hydrogen platform blocks to systems with electrolysis power of 100 MW or more. The system’s overall efficiency of 77 percent, along with the system’s high availability, results in low hydrogen costs, it claimed. The blocks are based on S450 stack technology and the systems are designed for indoor installation.
Toyota The Japan Fine Ceramic Center and the Japan Fine Ceramic Center have developed a new observation technique in which test samples are placed in a precise simulation of a fuel cell stack in order to observe the coarsening process at all stages of power generation. “The focus of that research is the way the platinum in the fuel cell stack catalyst ‘roughens’ over time, said Toyota. “These particle-level changes have an impact on the metal’s performance by supporting a chemical reaction between the hydrogen fuel and the oxygen in the air, creating electricity that powers the vehicle’s engine.” Coarsening is a process in which particles of different sizes are transformed into smaller particles with a larger average size.
Nigerian researchers have shown that energy systems combining diesel generators, solar, wind, hydrogen and batteries can achieve a “renewable fraction” of 98-100 percent in the cities of Abuja and Anyigba. “Like a battery bank, functional analysis of the hydrogen system shows that it can mitigate the intermittency of solar panels and wind resources,” the team said.Energy balance and a multi-criteria approach to dimensioning a renewable energy hybrid system with hydrogen storage”, which was published recently e-Prime – Advances in electrical engineering, electronics and energy. “This study clarifies the potential and benefits of hydrogen energy storage.”
The the European Commission is admitted A €450 million ($490 million) program to support renewable hydrogen production in Italy. Public support is granted as direct grants to cover investment costs, a maximum of 20 million euros per project.
