My latest for @BloombergNEF: "We need to talk about #nuclear power. And I mean really talk, in a truth-and-reconciliation, moving-forward kind of way, not a let’s-all-shout-slogans-at-each-other, my-tribe-versus-your-tribe kind of way." about.bnef.com/blog/liebreich…
Trigger warning: whether you are a lifelong anti-#nuclear campaigner or the technology’s most ardent fan, my latest piece for @BloombergNEF might make for uncomfortable reading: about.bnef.com/blog/liebreich…
Wind and solar accounted just 7% of global power in 2018, 3% of final energy. Respect where it is due: this is an extraordinary achievement from a standing start at the turn of the century, in the face of aggressive pushback from cash-rich incumbents. about.bnef.com/blog/liebreich…
To decarbonize the power system in line with the 2C or 1.5C warming targets via wind and solar alone (assuming moderate economic growth) you would have to add 2x to 4x as much capacity in the next decade as has been added in total in the last two decades. about.bnef.com/blog/liebreich…
But power is only responsible for 42% of emissions, and the road to decarbonizing the rest also runs through electricity. Even assuming vast efficiency improvements, hitting 1.5 to 2C with wind and solar alone means multiplying capacity 5x-10x in 11 years! about.bnef.com/blog/liebreich…
Sure you still want to lose the 10% of global electricity generated by existing nuclear plants - which is zero-carbon and only costs around $33.50 per MWh - at the same time? about.bnef.com/blog/liebreich…

On the day of the opening ceremony of the Beijing Olympics, a short thread. 30 years ago in 1992, I was very proud to be walking in the opening ceremony of the Albertville Olympics. No, that's not me carrying the flag, I was only a mid-ranked moguls skier.
OK, since you asked...
Here's another one. Yes, that is me. No, it's not a one-piece. And no, we didn't wear helmets.
My discussion with Ban Ki Moon on @MLCleaningUp, covered a lot of ground - lessons from the pandemic, energy access, climate change, human rights, the Olympics - and it contained some real bombshells. IN this thread, just some of the highlights... 1/17 cleaningup.live/p/ep70-eh/
"We are suffering this pandemic because the world's leaders have forgotten past experiences. I sincerely hope that when we get over this pandemic, political leaders remember what we have been suffering, and don’t repeat the same foolish mistakes." 2/17
"I telephoned Tedros at the WHO and said you may not be able to handle this crisis alone. Then President Trump withdrew membership from the WHO rather than supporting it, and that was the beginning of the problems for the international community." 3/17
If you really want to know about blue hydrogen, whether it is inevitably incompatible with net zero or whether it is within the laws of physics and engineering - and the wit of humans - to do it right, here's a new paper, written by 16 researchers. 1/4 chemrxiv.org/engage/api-gat…
It says "our main conclusion is that, if the above requirements [limits on CO2 and methane emissions] are met, blue hydrogen can be close to green hydrogen in terms of impacts on climate change and can thus play an important and complementary role" on the road to net zero. 2/4
In fact, the new paper says almost exactly what I was saying before #bluehydrogengate blew up: "I've got nothing against blue hydrogen, as long as there are no fugitive [methane] emissions and [it has] 100% capture, or high-90s per cent capture.” 3/4 rechargenews.com/energy-transit…
So, my lovelies, I just dropped Version 4 of the Clean Hydrogen Ladder! For anyone new to all this, the ladder is my attempt to put use cases for clean hydrogen into some sort of merit order, because not all use cases are equally likely to succeed. 1/10
By way of background, the ladder is intended to debunk the naive view of clean hydrogen as the Swiss Army Knife of the future net zero economy. Just because you could *technically* do something with clean hydrogen, it doesn't mean you will. Thanks for the image idea, Paul! 2/10
This time round, I have written up the Clean Hydrogen Ladder on LinkedIn, so you can see some of my thinking. In the piece I go through the various types of sector where hydrogen might, or might not, play a role. 3/10 linkedin.com/pulse/clean-hy…
My latest for @BloombergNEF: Climate action - It's The Trade, Stupid. Why free trade and fixing the WTO are more important than carbon border adjustments. about.bnef.com/blog/liebreich…
Although dealing with carbon leakage is certainly an important question, it is not the most important question. What is critical is to unleash trade to play its full role in support of climate action. about.bnef.com/blog/liebreich…
How can trade accelerate the uptake of clean technologies? How can it help poorer countries leapfrog to low-carbon solutions? How can it help decarbonize corporate supply chains? These questions will decide the speed, fairness and success of the global net-zero transition.
OK folks, you want zero-emissions construction, forestry and farming machines? The future may be hydrogen, but not as you know it. I spent yesterday with Lord Bamford and his team at @JCBmachines's secret test quarry near Uttoxeter. This puppy burns hydrogen in a thermal engine!
Engineers at @JCBmachines have developed a range of battery machines, which work great if they are not in constant use and have a grid connection. For off-grid, continuous use they tried fuel cells, but found them complex and expensive. Et voila, they developed a hydrogen engine!
I was well impressed. I'm a mech engineer with a thing for fluid dynamics and thermodynamics. The first ever IC engine ran on hydrogen in 1807, but solving all its problems (hotspots producing NOx, steam removal, reliability, etc) is hard. If @JCBmachines has done it, it's a BFD!
