Thread by @Bellona_EU

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:
➕additionality
⌛️temporal matching
🗺️geographic correlation

4/➕#Additionality: to ensure that hydrogen doesn't cannibalise the available #renewables (RES) that we need to decarbonise the power sector, while driving a boom in new RES deployment. euractiv.com/section/energy…

5/ Some great work👏 by @transenv’s @Geert_DC on that resulted in a letter with @beuc on the consumer cost impact of lacking #additionality rules⬇️

6/⌛️Temporal matching to use #electricity at the same time as its production. Storage is difficult for electricity, so it should be used when generated. If not, demand increases and is met with #fossilfuels. Check out innovator @energy_tag in this space.

7/🗺️Geographic correlation ensures electricity is used in the same area where it's produced. It’s the closest thing to connecting the #renewable generation and the #electrolyser when producing from the grid.

8/ What’s left of these principles after 2 years of delays?🤔 A large chunk of it, but we will have to wait until 2030 to see this happening in reality⬇️

9/ Two long transitional periods on #additionality (until 2028) and temporal matching (until 2030) mean that the #HydrogenEconomy kick-start will increase📈 #emissions in the short term⚠️: considering the climate emergency, this is a major red flag.

10/ The rules were also loosened for #additionality where grids already have a low carbon intensity, regardless of whether this is driven by #nuclear rather than RES.

Some more in this @FT piece: ft.com/content/5c3200… (with a quote from our very own @LoviMarta)👏

11/ If you have an #additional minute to look beyond hydrogen, the @isfcentre interviewed 🎙️#PeterSweatman @ClimateSt, talking about his career in #SustainableFinance and sharing insights on energy efficiency financing⬇️

12/ And with that, we wrap up the #CleanTechEU thread🧵! Thank you for reading.
