Was there a massive leak of a dangerous greenhouse gas in Iceland🇮🇸 in 2011-or was it a data📈 reporting error? Emission databases show that the Norðurál aluminium factory🏭 released 60 tons of SF₆ in 2011 — but no such emissions in any other year. 🔌💡 industrydecarbonization.com/news/errors-... 🧵

Thanks, @hanno.hboeck.de for a stunning investigation into major greenhouse gas reporting errors! Was a pleasure to translate your talk. #c3lingo

The two curves here should be the same. Obviously, they are not. If you are at #39c3 and want to learn about the unusual things I found in Greenhouse Gas Emission Databases, come to stage One at 11h fahrplan.events.ccc.de/congress/202... There's a livestream: streaming.media.ccc.de/39c3/one

The article that highlighted a powerful greenhouse gas in Nike shoes in 1992 🌍👟 I recently wrote about high SF6 emissions from a factory in Germany. SF6 is the most powerful known greenhouse gas, and I also dug a bit into its history. Until 2006, Nike used SF6 in its shoes. /thread 🔌💡 🧵

The Worst Greenhouse Gas on Planet Earth: #SF6 💨🟡🌍🔥 Scientists have identified a factory in Germany emitting far more of the world's most damaging greenhouse gas than officially reported. A short video presentation 🎥 🔌💡 www.youtube.com/watch?v=OaJs...

It's the worst known greenhouse gas, and a factory in Southern Germany emits a lot of it 🌍🏡💨🏭 Sulfur Hexafluoride or SF6 is a gas that has been used in Nike shoes (until 2006), Magnesium production, soundproof windows, and electric switchgear. 🔌💡 /thread 🧵 industrydecarbonization.com/news/super-e...

In collaboration with Belgian journalist Jelle De Mey, I wrote about massive SF6 emissions from a Solvay factory in Southern Germany for @apache.be apache.be/2025/12/11/b...

De chemische fabriek van Solvay in Duitsland stoot jaarlijks 30 ton SF6 uit, het sterkste broeikasgas dat we kennen: 500x meer dan wat het bedrijf rapporteert. De overheid beveelt het Belgische bedrijf om de uitstoot te doen dalen, maar die eis vecht Solvay nu aan. apache.be/2025/12/11/b...

The UNFCCC makes it needlessly difficult to download emission data📊📈 The UNFCCC🇺🇳 is most famously known for being the organizer of the climate conferences (COPs). However, they also play an important role in collecting and managing emission data. 🔌💡 industrydecarbonization.com/news/why-is-... 🧵

Is Enerkem's Waste Gasification technology a Failure or a promising Climate Solution? Gasification of waste🗑️ and biomass🪵 could be an enormously helpful tool to make circular+renewable chemicals. Yet, the list of failed gasification projects is long.🔌💡 🧵 industrydecarbonization.com/news/is-ener...

CCS does not look like you may think💨🏭 Carbon Capture and Storage is certainly one of the more controversial technologies to mitigate climate change. When I observe discussions about it, I am often frustrated. 🔌💡 🧵

A new idea about how to make clean Hydrogen that fits into an existing industry? ✨🌱💧 Clean Hydrogen🌱💧 will be more difficult than we might've hoped, but we need it. Just decarbonizing the fossil🦖 Hydrogen industry is a massive undertaking. 🔌💡 🧵 industrydecarbonization.com/news/this-hy...

I was recently asked where I would see useful applications of CCS. My answer was: Cement🧱🪨 and Biomethane🐄🌱🏭 Most won't be surprised that I said Cement. Yet, Biomethane is not what people usually have in mind. But bear with me, it makes a lot of sense.🔌💡 🧵 industrydecarbonization.com/news/you-wan...

What's going on with ArcelorMittal's steel decarbonization projects Steelanol and Torero in Belgium? 🔩🔗🏭 Recently, several Belgian publications reported that ArcelorMittal may shutdown the Steelanol plant at its site in Ghent. Steelanol converts steel mill off-gases into Ethanol. 🔌💡 🧵

Warum es in Thüringen keine Methanol-Produktion aus dem CO2 einer Müllverbrennungsanlage geben wird: www.golem.de/news/geschei...

Warum ich Gaskraftwerke mit CCS für extrem unrealistisch halte - u.A: geringe CO2-Konzentration, langfristig durch EE-Ausbau immer unwirtschaftlicher www.rosalux.de/news/id/5359... @rosaluxstiftung.bsky.social

We have to talk about burning trash🗑️🔥 Waste incinerators are an enormous source of CO2 🏭💨🌎. For example, in Germany, a country where waste-to-energy is common, their emissions are higher than those of cement 🔌💡 🧵 industrydecarbonization.com/news/just-st...

A huge proportion of climate solutions journalism is focused entirely on 'we promise this can be fixed without you having to change anything', and they'll accept wild, absurd and almost fraudulently misleading greenwashing uncritically so that message can be preserved (also see: the seaweed guy)

Running cars on E-Fuels, made with CO2 from the air and green Hydrogen?🚗⛽🌿⚡ In 2022, Siemens Energy, Porsche & HIF inaugurated the Haru Oni pilot plant in Chile, which turns CO2 and Hydrogen into Methanol + small amounts of Gasoline. How's it going? 🔌💡 🧵 industrydecarbonization.com/news/whats-u...

And the quote is from here: (no cheating) www.bbc.com/news/world-e...

"At both the national and international level, the development of technologies to capture and store CO2 has taken longer, been more difficult and more costly than expected," says [politician]. What year was this quote from?

Do you need Hydrogen to power a small ship🚢 covering a distance of 5 kilometers? No. It can easily be done with batteries🔋 Yet the MF Hydra in 🇳🇴 runs on LH2💧, transported🚚 more than 1,300km from🇩🇪 Where and how is that Hydrogen produced? Unclear. 🎥 www.youtube.com/watch?v=DhzN...

Imagine you want to produce E-Fuels⚡⛽ but the power company does not want to sell to you🔌💡 That appears to be what E-Fuels producers faced in Iceland🇮🇸. The country uses 100% renewable⚡. Yet, Iceland's Landsvirkjun does not want to sell to E-Fuels projects🧵 industrydecarbonization.com/news/iceland...

It's tough to overstate just how shockingly unusual an article like this is. Despite the fact that this is the response of the vast, vast majority of neighbours for both wind and solar farms, they are mostly erased from existence in coverage of attitudes of neighbours to utility-scale renewables

What happened to Linde's Hydrogen Electrolyzer in Leuna/Germany, & what mystery hydrogen powers a ferry in Norway? 🌱💧🚢🇳🇴 In the image, you can see a steam methane reformer. It turns fossil gas into hydrogen & a lot of CO2, which is how H2 is made today.🏭🔥🌏 industrydecarbonization.com/news/why-pow...

The MF Hydra is Norway's Ship of the Year 2021. It is also the first and only ship powered by Liquefied Hydrogen (LH₂). And... I don't know where to start... 🚢 This ship isn't just running on Hydrogen, it is running on Liquefied Hydrogen.

How did E-Methanol production progress in the past few years? ⚡🧪🧵 In 2022, I wrote an article about E-Methanol production methods for the shipping news page Fathom World, which is no longer online. Well, if you follow me, you know I write a lot about E-Methanol, and follow those projects closely.

It's an unfortunate reality that many announced cleantech projects never get built — or much later than expected. I am currently checking a few articles I wrote in 2022+23 for Fathom World, a shipping news site that is no longer online. I want to make sure those old articles stay accessible.🔌💡 🏭🌿🏗️⏳🧵

A fossil-free plastics plant could start production in a few years in Belgium - with a technology that is currently used to make plastics from coal. 🌿🧪🏭 #plastics #mto #chemicals #decarbonization 🔌💡

In discussions about clean Hydrogen, there is a popular idea floating around, particularly in countries like Germany or Japan that import most of their fossil fuel energy. Instead of importing fossil fuels, we will import Hydrogen in the future from places where renewables are cheap. ⚡💧🚢🏭 🔌💡 🧵

Last year, Danish wind energy giant Ørsted pulled the plug for the planned E-Methanol factory FlagshipONE in Sweden - despite the fact that the project had subsidies and investment promises, and a "final investment decision." Ørsted said it couldn't secure offtake agreements 🚢🛢️🔌💡🧵

Vor gut 2 Jahren wurde in Chile das Projekt Haru Oni für die Produktion von E-Fuels in Betrieb genommen. Es hat viel Aufmerksamkeit bekommen & dazu beigetragen, die Idee von E-Fuels ⚡⛽ als Alternative zu Elektromobilität🔋 und alternativen Verkehrsmitteln🚲🚆 zu etablieren.🧵

There was no Q&A after my #38C3 talk, but in the chat, someone asked an interesting question. I said in that Methanol is the simplest carbon-containing liquid, the person remarked that this would instead be formic acic + asked whether using formic acid instead of methanol would be interesting.

Reminder: I'll be giving a talk about the role Green Methanol could play in the energy transition, at 12pm CET (that's in a bit less than an hour) #38C3 fahrplan.events.ccc.de/congress/202... Livestream: streaming.media.ccc.de/38c3/glitch

I'm at the #38C3 Chaos Communication Congress + will be giving a talk on day 4 (30th, 12pm CET) about Green Methanol 🍃🛢️ fahrplan.events.ccc.de/congress/202... livestream at streaming.media.ccc.de/38c3/glitch Feel free to reach out if you're here + want to discuss cleantech / decarbonization. 🔌💡

But that is based on a very sketchy assumption. It only looks at electric energy inputs, not at total energy. More in my latest newsletter: industrydecarbonization.com/news/the-pro...

The only operational large-scale methane pyrolysis plant currently does not sell any hydrogen. It just flares it. Methane pyrolysis is often pitched as a "more efificent" method than electrolysis for hydrogen production.

Methane pyrolysis, first and foremost, produces carbon. It only produces around 1 ton of hydrogen per unit of carbon. That carbon, if used in various industrial applications, also has an emission footprint.

Lately, I have seen an increasing number of posts mentioning something called methane pyrolysis or "turquoise hydrogen" as a potential way to produce clean hydrogen from fossil gas. But the claims that surround this turquoise hydrogen don't stand up to scrunity. 🧵 🔌💡

Glass production is an example of an industrial processes that cause CO2 emissions even if powered by clean energy. Carbon-containing raw materials release carbon dioxide during the production process. I recently learned about an idea that sounded appealing. 🪟🍾🏭 🔌💡 🧵

I have somewhat special questions that have to do with the climate effects of acids vs. bases, and the production of NaOH. It touches upon similar issues like ocean alcalinity enhancements. Any recommendations for a climate scientist I should talk to who would love to explain chemisty to me?

I read some online posts that Sweden's mining company LKAB is "putting the brakes" on green steel. LKAB is involved in a pioneering hydrogen green steel project, and it should concern us if these projects are in trouble. I tried understanding what's excatly going on. 🧵 🍃⚒️ 🔌💡

Is green methanol the perfect partner to a mostly-electrified economy? Better than hydrogen? Methanol is easy to transport, store, needed in abundance for chemicals/dense fuels anyway. What is the current status of methanol projects? Read @hanno.hboeck.de's latest newsletter to find out!

There's been a lot of talk about green hydrogen lately. But hydrogen is difficult to transport & store. One option to deal with this is to convert H2 into other chemicals. An obvious choices is Methanol, the simplest carbon-containing liquid. 🧵🍃🛢️ 🔌💡 industrydecarbonization.com/news/from-co...

This widely shared graphic uses a trick to make its message appear stronger than it is. It seems to show a strong correlation between energy consumption + wealth of a country. By using a logscale, the correlation appears much stronger than it is. I made a video ⚡💸🎥 www.youtube.com/watch?v=2xZ6...

E-Methanol made from green hydrogen&CO2 is often named as a promising future shipping fuel. Lately, there were some discouraging news for green methanol. The energy company Ørsted had cancelled plans for an e-methanol factory FlagshipONE, which already had a "final" investment decision. 🔌💡 🚢 ⛽ 🧵

Remain blown away by how often Texas is presented as "beating" California due to a free market, 'desire to build' etc. So I ran the numbers, and wrote a blog. And - no: Texas isn't a magical centrist fantasy demonstration that deregulation = climate action ketanjoshi.co/2024/08/12/t...

Was preparing a talk about industrial emissions & like to illustrate with local examples. Place is is close to a chemical cluster in German state Saxony-Anhalt. Pic (CC by-sa FotoFitti) left is a coalplant, largest emission source in S.Anhalt. I want to talk about the 🏭 on the right. 🔌💡 🧵

Interest in Carbon Capture and Storage has increased in recent years. A discussion in Norway about plans for the Hammerfest LNG raises important questions about the costs of CCS industrydecarbonization.com/news/is-carb... 🔌💡 🧵

Followerpower: I'm wondering what the current state of E-Methane/CO2/H2-to-CH4 technology in real production is. I know of a plant in Denmark (Nature Energy) that claims to have a production capacity between 2-3.5 million cubic meters per year. Anything larger anywhere?
