1/ Welcome to the bi-weekly #CleanTechEU thread!🧵👇
This week is a dive into the recently adopted #hydrogen delegated act on #additionality, what we asked for, why, and what made it to the final text & what got lost in compromises.🔎

2/ 1st things 1st: making #RenewableHydrogen means needing #RenewableElectricity ⚡️
When connecting an electrolyser to most of #EU’s electricity grids, the #H2 produced will have a very high #CarbonFootprint🏭👣

3/ But, this can be fixed. Here are a few rules that can ensure that #hydrogen produced on the grid has a minimal climate impact:

1/9 Dedicating #RenewableElectricity to #Hydrogen cannot free the EU from #RussianGas.⚠️ What can, is using renewable electricity efficiently.

2/9 How we use each TWh of electricity has a huge impact on whether we break free⛓️ from #RussianGas.
Using it in #HeatPumps displaces three times more fossil gas than using it to produce.👇

3/9 #REPowerEU foresees the total installed wind 🌬️& PV ☀️capacity to increase from today’s 360 GW to almost 1000 GW + 80 GW of renewables earmarked for #H2.
This will produce over 1000 TWh of electricity⚡️ per year. That’s the 🇫🇷 & 🇩🇪 demand combined.

As part of the #GreenDeal, EU aims at a reduction in greenhouse gases of 55% by 2030 & full climate neutrality by 2050 🍃Will we have enough renewable electricity to meet the decarbonisation objectives? @RonnieBelmans @ReisPiero & @PieterVingerhoe answer📌bit.ly/3n1bDsl
📑Studies show there is little room for supplying the additional #RenewableElectricity by 2030.
➡️This policy brief, part of the #EUI4CoFoE campaign, addresses potential priorities to cope with the remaining needs for energy towards carbon neutrality.

The authors suggest 5 policy actions by 2030 and 2050, addressing #cooperation with neighbouring countries, prioritising applications where electrification brings an enormous gain in efficiency such as passenger transport🚄🚃and hydrogen production and more.
#Climate needs #electrification AND #hydrogen.
Both compete for #renewableelectricity, policy and infrastructure support. Policy makers have to take decisions, secure expectations, avoid further fossil lock-in
Our paper offers guidance.

#efuels(right) replace fossils without the end-use transformation required by (direct) #electrification(left)
This promises to make combustion technologies and fossil infrastructure part of the climate solution;
yet, shifting the burden to the supply side has limitations…

#Efuels require 2 – 14 times more (renewable) electricity than a direct #electrification (e.g. electric cars are five times more efficient)
Remember, (growing) renewable power capacity is far from fully meeting only today’s electricity demand.
(no regret: #renewableexpansion)
