Global energy utilities are facing a growing risk of cyberattacks with potentially severe financial damage. A survey by Siemens and the Ponemon Institute finds that 54% of utility respondents fear an attack on critical infrastructure in the next 12 months. To mitigate this risk, utilities need to improve the interface between Operational Technology (OT) and IT systems.
To test Power-to-Gas systems locally, Fraunhofer ISE installed a modular hydrogen injection system in the local gas distribution network in Freiburg, southwest Germany. Researchers coupled an electrolyzer with 120 kW electric connection power with a small hydrogen unit that is capable of storing 300 kWh of chemical energy.
The cost of producing hydrogen gas from renewables is forecast to fall sharply over the next decade, providing an affordable fuel to decarbonise the energy and transport sectors. In Germany and Texas, RES hydrogen costs could fall to $1.40 a kilogram by 2030 from the current range of $2.50 to $6.80, according to research published in Nature Energy.
