Discover and read the best of Twitter Threads about #decarbonization

Most recents (24)

My entire adult life I've worked on #decarbonization technologies guided by the question, "what can I contribute to humanity to help evolve us into a more advanced alien species?" #Lithium for batteries was a good place to start.
So I spent half a decade developing technologies and natural resources for a new world that emits less CO2 and requires less mining than the old world. However lithium will always have a tiny footprint even at full scale. That's actually the point. ImageImageImageImage
Meanwhile, we produce almost as much structural metal today as we produce coal. And because metal makes advanced alien species possible, it will be produced forever. Even "as time goes to infinity", primary metal will be needed because nothing is "infinitely recyclable". Image

"#NegativeEmissionsTechnologies are needed to achieve #NetZero emissions, but their deployment will depend on regional & national circumstances, technology availability, & decarbonization strategies."

In this regard, a new study is done. Details below in a 🧵

#ClimateChange is a natural process that occurs over 1000s of years. The reason they say #GlobalWarming is wreaking havoc is due to the human caused CO2 increase. CO2 is necessary for plants & trees to produce food. Due to excessive deforestation and burning of fossil fuels…… Image

🚛🌍🌱 Dalmia Cement begins transition to cleaner logistics with LNG trucks

a MASSIVE step forward towards building a 'green' supply chain with the its 1st fleet of LNG trucks in collab with GreenLine Logistics.

The 35 LNG trucks order is the biggest in the cement sector
Dalmia Cement shifts to 10% green transport by FY24.
Both LNG truck types cover a range of 50-600kms for inbound & outbound logistics.
CO2 emissions reduced by ~28%, SOx emissions by upto 100%, NOx emissions by up to 59%, and Particulate Matter by up to 91%.
🌿 Dalmia Cement's overall CO2 emissions have come down from 670 kg per tonne to 467 kg per tonne.

💪🏽The company's focus - replacing conventional fuels & raw materials with alternative solutions, expanding its renewable energy portfolio, & using green vehicles in logistics

Picture of the Week: Speed of change around #energytransition is accelerating. Last year the @IEA projected that #renewableenergy installations would be 1800GW over the next five years. Now they are saying that it will be 2,400GW which is the installed capacity of #China.
Why is the #energytransition accelerating:
1. Geopolitics - #Ukrainian crisis has forced #Europe to accelerate #decarbonization. It has also been a wake up call for #China who is a huge #energy importer.
Why is the #energytransition accelerating:
2. Opportunity - #EVs, #batteries, #heatpumps and #Solar are multi-billion dollar markets growing at circa 40% per annum and are attracting the best entrepreneurs and businesses across the world

(1/9) I’ve seen a lot of op-eds about how awful it is that #CCS was included in the #IRA. Most lack nuance, because they haven’t clocked that the #energytransition isn’t just about the power sector anymore. Sorry #energytwitter. So, a 🧵 on why carbon capture still has a place.
(2/9) First, I get this. I was a huge #CCS skeptic. Two things changed my mind: modelling pathways to #netzero for materials with my @BloombergNEF team, and the #BNEFNEO team's carbon budgets for industry. Sobering work that taught me a lot.
(3/9) Some industries just can’t do without CCS. Process emissions are just as harmful as combustion. And we’re past the point where abatement of emissions is enough. That means removals, which means #DirectAirCapture.

🌍 Our 2022 #Science Board Symposium on "The #Emergent #PoliticalEconomy or #ClimateChange" kicks off with opening remarks from President David Krakauer.

Follow this 🧵 as we provide live coverage of this event all day...
"For those of you who think behavior change can prevent #ClimateChange...behavior WILL change when climate changes. Shutdowns from the pandemic resulted in a reduction of #C02 emissions of about 7.5%."

"We *used* to talk about #ClimateChange used to be something that would happen to people in Bangladesh fifty years from now."

Is humidity control just for warm-humid weather? Or can you grow mold in winter?

A little thread for the part of #energytwitter that hasn't seen the bigger picture of #buildingscience.

First, if you think you're immune to moisture & mold problems because your climate is dry in summer, let me invite you to take a look inside your fridge. What's inside that container in the back that you've forgotten for a couple of months.

Extreme example: Family in Kansas had a poorly insulated building enclosure. They kept the inside relative humidity at 50% while outdoor temperature was -5 °F.

Yes, that's ice on the walls & ceiling inside the house. Here are the details:

In 2021, Europe imported ~158 Bcm of Russian #natgas.
By 2027, that figure is (supposedly) going to be 0 Bcm.

How do the Europeans get that done? Time for a 🧵
1/n Firstly, how does Europe plan to move away from Russian gas?

1. Moar US #LNG.
2. Increased energy efficiency.
3. More renewable energy deployment.
4. Healthy doses of optimism and idealism.

See @EU_Commission statement below.…
2/n Specifically, within the EU's statement is the commitment to increase LNG imports from the US by:

15 Bcm in 2022
50 Bcm by [2027]

Seems pretty doable? Until you actually dig into it.

NEW PAPER AND THREAD: Why are climate economists' favorite tools (carbon pricing/emissions trading) so despised?

@dolanecon shows where economists have missed the mark or failed to make themselves understood - and how they can do better.…
Are economists are wrong when they advocate carbon taxes/emissions trading as central elements of climate policy? Plenty of dedicated climate activists (some of whom are economists themselves) say "yes."
.@DrVolts writes that "climate economics and climate economists have blown it pretty comprehensively." @Noahpinion says that "climate economics has almost completely failed to be useful to the national policy discourse."……

In May of 2021, @EconTodd made a note of that morning's @WSJ headline during his interview with @stefan_wieler of @axpo — Russian troops had amassed on #Ukraine️'s border. Buchholz asked Wieler what that could mean for #gas and #oil prices.
@EconTodd @WSJ @stefan_wieler @axpo You can listen to his episode here for a little refresher:
Around the 20 minute mark, @stefan_wieler remarks on the lack of real-time #data in the #commodities space and the difficulty it creates for the #globaleconomy at large.

#Italy can cut its #CO2 emissions by up to 97% and this can lead to *lower* #energy prices.

Hard to believe? Check out our new paper in #RSER:…

@ImperialBiz @EnergyFuturesIC @CogImperial
#EnergyScope is an #optimization model looking at the whole-energy system, including #electricity, #heating and #transport.

We present a new version of the model and propose it to devise deep #decarbonization scenarios for #Italy, like this one!

How does a 97% decarbonized Italy look like?

Only a few days into @COP26, we’re already hearing global commitments and plans. This will all culminate in a day dedicated to the built environment next week. In the meantime, I’ll share my #COP26 thoughts in this thread.
I encourage you all to explore this wonderful virtual exhibition of the world's greenest buildings at @COP26. These projects serve as examples to all of us in the real estate and building sectors. @wef…
As I’ve said many times, @COP26 must be a turning point for the real estate industry. Buildings are responsible for 40% of carbon emissions worldwide. Action from this industry is crucial to meeting climate goals.…

Carbon capture and sequestration (or CCS) is being touted by some as a potential solution for #decarbonization in industries like cement and steelmaking. But how promising of a solution is it? A deep dive 🧵
There is only limited experience with CCS at industrial facilities beyond gas processing. Only one steel mill in the entire world (and no cement plants), capture CO2. Little info is available about how much they capture, and key info about cost and reliability is missing. Image
Only 3 of 26 CCS projects currently operating in the world have reported any information that would allow their “capture rates” to be determined. Without this information, it’s impossible to show that any existing CCS projects are economically, financially or technically viable.
