🚨 New paper 🚨
Green #hydrogen and derived #efuels are critical for #climate #mitigation, but when will they be available at scale?
In a new Nature Energy study, we look at a key bottleneck: the market ramp-up of #electrolysis capacity.

2/ #GreenHydrogen, produced from renewable electricity via electrolysis, is vital for the #EnergyTransition. In the #EnergyCrisis hydrogen is also considered an option to limit Europe's fossil fuel imports.
However, scaling up supply is a huge challenge!

3/ There's a lot of momentum in electrolysis project announcements. This is also much needed because global capacity needs to grow a staggering 6,000-8,000-fold from 2021-2050 to meet #NetZero scenarios. Yet, most projects still lack an FID, making them uncertain. 
#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)

Our review paper on recent advances in solid oxide cells for #electrolysis has been published today in @ScienceMagazine ( science.sciencemag.org/content/370/65… ) Here are the main points from the paper (a thread, 1/15) 👇
Electrolysis (using electricity to drive chemical reactions) is a key technology for tackling #CO2emissions in the areas of our economy that are difficult to #decarbonize: heavy transport (planes, ships, trucks) and the production of chemicals, steel, cement, and glass. (2/15)
For heavy transport, e.g. large planes or container ships, direct electrification (batteries) is not an option due to low energy density of batteries compared to liquid fuels. Climate-friendly fuels can be made by combining electrolysis with chemical synthesis (e.g. FT). (3/15)
