No-regret #hydrogen:
Charting early steps for Hā‚‚ infrastructure in Europe.

šŸ‘‰Summary of conclusions of a new study by @AgoraEW @AFRY_global @Ma_Deutsch @gnievchenko (1/17)

The idea behind this study is that future hydrogen demand is highly uncertain and we donā€™t want to spend tens of billions of euros to repurpose a network which wonā€™t be needed. For instance, hydrogen in ground transport is a hotly debated topic

Similar things can be said about heat. 40% of todayā€™s industrial natural gas use in the EU goes to heat below 100Ā°C and therefore is within range of electric heat pumps ā€“ whose performance factors far exceed 100%. (3/17)


Even for higher temperatures, a range of power-to-heat (PtH) options can be more energy-efficient than hydrogen and should be considered first. Available PtH technologies can cover all temperature levels needed in industrial production (e.g. electric arc furnace: 3500Ā°C). (4/17)


In our view, hydrogen use for feedstock and chemical reactions is the only inescapable source of industrial hydrogen demand in Europe that does not lend itself to electrification. Examples include ammonia, steel, and petrochemical industries. (5/17)
Let's talk honestly about "informed consent."
Someone with decades of training gives someone with none advice usually packed into 1-3 mins. Huge amount is based on trust. Huge potential for bias built in. But also there is no obligation to provide real alternative options.


I am classified as 'gifted' (obnoxious and ableist term). I mention because of what I am about to say. You all know that I was an ambulatory wheelchair user previously - could stand - but contractures have ended that. When I pleaded for physio, turned down. But did you know...

I recently was chatting with a doctor I know and explaining what happened and the day the physiatrist told me it was too late and nothing could be done. The doctor asked if I'd like one of her friends/colleagues to give second opinion. I said yes please! So...

She said can you send me MRI and other imaging they did to determine it wasn't possible to address your contractures.

Me: What?
Dr.: They did a MRI first before deciding right?
Me: No
Dr: What did they do??!
Me: Examined me for 2 minutes.
Dr: I am very angry rn. Can't talk.

My point is you don't even know if you are making "informed" decisions because the only source of information you have is the person who has already decided what they think you should do. And may I remind you of a word called 'compliance.'
