Potentials and risks for climate targets
Hydrogen-based fuels should primarily be used in sectors such as aviation or industrial processes that cannot be electrified, finds a team of researchers. Producing these fuels is too inefficient, costly and their availability too uncertain, to broadly replace fossil fuels for instance in cars or heating houses. For most sectors, directly using electricity for instance in battery electric cars or heat pumps makes more economic sense. Universally relying on hydrogen-based fuels instead and keeping combustion technologies threatens to lock in a further fossil fuel dependency and greenhouse gas emissions.
“Hydrogen-based fuels can be a great clean energy carrier – yet great are also their costs and associated risks,” says lead author Falko Ueckerdt from the Potsdam Institute for Climate Impact Research (PIK). “Fuels based on hydrogen as a universal climate solution might be a bit of false promise. While they’re wonderfully

A Cool Monday With Slow Warming This Week The week begins on the cool side Monday with highs only in the 50s and a mix of sun and clouds. Temperatures slowly moderate through the week, with highs finally around average by the Fishing Opener weekend. Rain chances will move back in late this week into the weekend. - D.J. Kayser

Monday Weather Outlook
As we head into the work week here in the Twin Cities, it ll be a cool day with a mix of sun and clouds. Morning temperatures will start off around 40F, only climbing into the mid-50s for highs.
Researchers Warn Against Becoming Too Dependent On Hydrogen To Power Cars

another reason, The Guardian reports: scarcity and a subsequent dependence on fossil fuels.
Hydrogen-based fuels are already expensive, and while there’s also research to suggest that a growing demand could enable cheaper prices, even a large-scale swap isn’t going to create the infrastructure needed to distribute hydrogen on a large scale. Demand also isn’t going to immediately solve hydrogen’s other main issues: that you get less energy per unit volume than other fuels, that liquefaction (as in, the simple ability to easily refill a fuel tank at a pump) is challenging and costly, and hydrogen’s volatility. You’re going to face the same exact problems you currently have with the meager electric charging infrastructure, but things are amplified.
