The Hydrogen Stream: Fuel cells for large aircraft nearing development
In its bid to develop fuel cells for aircraft with over 100 seats within 24 months, ZeroAvia has revealed record-breaking hydrogen fuel cell performance tests. Meanwhile, Universal Hydrogen and local partners are teaming up to build hydrogen infrastructures for aviation in Japan amid a push towards hydrogen infrastructure and mobility.
Weekend Read: Light weight
When it comes to gravity batteries, pumped-hydro storage is the gold standard, but its cost and topography-specific limitations are driving innovations ranging from freight-train braking to super-dense liquids. We consider whether any of the new technologies can punch above their weight.
Weekend Read: Imminent comeback, imminent trouble
Once a European leader in PV deployment, the solar market in Czechia has slumbered for the last decade. Now, with growing public support and financing in place, momentum is building and a gigawatt-scale pipeline is taking shape. However, fresh challenges loom, as Marija Maisch reports.
