Boston Metal has a well progressed unique tech for electrochemical steel making Yes it’s raised a lot of capital and progress has been slower than hoped - but it works and could decarbonize the global steel industry.

One of the small joys of life: finding out that the old shoe that fit you perfectly hasn't been discontinued, so you can get another pair :)

Great perspective on Dutch geothermal energy strategy from two ex-oil + gas authors. > Focus on district heating schemes from known-good shallow-ish geothermal. > Stop wasting money on deep closed loop hopium projects. (Google translate from Dutch) energeia-nl.translate.goog/geothermie-v...

South German geothermal is primarily for district heat, but there is some electricity generation. The challenge is that Organic Rankine ⚡Generators really needs 180 degree heat to be cost effective, and you have to go to 5km+(with $$+ on drilling) to get there in that geo.

Windows 11 AI has a heavy footprint - uninstalling Copilot or other AI apps doesn't solve this. Instead - disable the WSAIFabric service - which prevents 2GB+ of WorkloadSessionHost (AI support) processes spawning.

Across Europe, only Norway seems to be at the right run-rate to reach 100% heat-pump based building heat in a 20 year time frame (50 new units per 1,000 households)

Next time someone asks you about energy and land use, maybe remind them that the ~35 million acres that currently grow corn for ethanol in the US could produce ~15 PWh per year of electricity from solar photovoltaics. That's ~3.5 times more than *total annual generation from all US power plants*.

Just like “esports” was really just League of Legends + investor enthusiasm. Next generation geothermal is really just Fervo + investor enthusiasm. (Overstatement but trueish)

We've spent the New Year selecting 10 takeaways that best represent the key changes and trends affecting the Irish electricity grid in 2025. Key takeaways 1-3: flatlining renewables to demand ratio, increasing imports via interconnectors, and wind dispatch down. (1/3)

We think 20th century coniferization policy for ancient woodland hammered & de-stabilised populations of woodland specialists, like Marsh Tits. We'd love to see more studies on this impact. Restoration is needed, but Marsh Tits likely also have other problems, e.g. competition, climate change. /end

Results from Enhanced Rock Weathering experiments are really all over the map. Here is the plot of reported removal rates (y-axis) vs. duration (x-axis) from Dupla et al. (2025).

Looks like Erebus will be the first floating wind project for the Irish sea. It's a demo project of 100MW and just won a bid in the latest blockbuster UK wind auction.

Conservatively estimated 32 millon hectares of land is used for producing 1,400 TWh of biofuel per year. If that land instead was covered* by solar panels, it would surpass the *total* current electricity production worldwide 🤯. *: Not that it should, just for comparison.

This was the Feldman Eco-park in Ukraine, which hosts facilities for bat researchers & rehabbers from Kharkiv University. No military targets, just deliberate murderous destruction by Putin's Russia. Park was recovering after being attacked & occupied in 2022, when Russians murdered two zookeepers.

@ericlipton.nytimes.com Your Hamm profile omitted salient information - aka that he has been persistently "over-optimistic" about shale reserves and production levels and has never been held to account. He is now leading the US into an era of expensive energy. powering-the-planet.ghost.io/less/

“than expected” is incorrect. “10 to 30 times less than the highest marketing claims of the most hyperbolic ERW companies” would be accurate. Their findings of 70 to 140kg per Ha per year is consistent with the median of previous academic research.

Martin Wolf makes a case that US CPI data has been massaged down by the Trump Administration at best. wolfstreet.com/2025/12/18/t...

When people say technology transitions take time, always remember that the entire US Steel industry converted from open hearth to blast furnaces in a single decade because they were cheaper.

Not all biomethane is the same - feedstock matters a great deal. Biomethane from dedicated energy crops provides a minimal benefit vs. fossil gas - particularly if supply chain leaks are substantial.

Precision fermented dairy using local dextrose/glucose from sugarcane should be tantalizingly close to animal production costs in high cost areas like West Africa. Rather than trying to solve the (frankly insurmountable) structural cost disadvantages of animal-sourced dairy - why not leapfrog?

Dear @adobe.com acrobat reader. No, I do not need an AI document summary of my tax return PDF. But I do need you not to crash every time I search it.

We Are Eating the Earth is a must read. There's no viable future on Earth without deep agricultural reform. It's our largest and least talked about planetary impact, especially meat production. @mikegrunwald.bsky.social cuts thru the feel good "regenerative ranching" promos show it doesn't scale.

This is a great summary of the drawbacks of waste-to-energy schemes that brand themselves as "circular economy" wins, but are more emissions intensive vs. proper land-filling. www.linkedin.com/pulse/waste-...

New govt biomethane strategy reiterates that the govt wants to take 120,000 hectares out of grass production and use it to grow feedstock for anaerobic digesters (AD). AD that doesn't use waste streams (like this) is not climate-positive due to land-use impacts. assets.gov.ie/static/docum...

I was taught that changes in nitrogen spreading rates shows up quickly in water quality - but this doesn't seem to always be true. A new paper calculates a subsoil persistence time of 30 years (!) for excess nitrates in the Mississippi basin. Yike. www.sciencedirect.com/science/arti...

Technical strategies for reducing nitrous oxide emissions from agriculture (pastured + cropped) don't get a lot of airtime in the climate solution space. Here's a roundup I did last year of the options: www.linkedin.com/pulse/abatin...

My gas boiler is the single most temperamental, breakdown-prone piece of kit in my house. I can’t wait to get rid of it just so I don’t have to deal with it - irrespective of its climate impact.

my latest investigation for @consumerreports.org is based on months of reporting and 60+ lab tests of leading protein supplements we found that most protein powders and shakes have more lead in one serving than our experts say is safe to have in a day (🧵) www.consumerreports.org/lead/protein...

I’m halfway through this and highly recommend so far!

Climate solutions are in weird split, where it's looking more and more likely that electricity generation and road transport will almost fully de-carbonize, but industry and agriculture are looking less likely.

Denmark's biogas strategy takes sustainability seriously by using organic waste streams rather than dedicated crops to supplement cattle slurry. For example, dedicated crops grown for biogas are limited to 5% of input. Ireland's biogas strategy relies on fresh grass input and is NOT sustainable.

A year ago I wrote about 5 startups trying to develop electrochemical/plasma alternatives to SMR/Haber-Bosch for Nitrogen Fertilizer. At the time I noted that a 1500x improvement was likely needed from current performance to be cost competitive. (1/2) www.linkedin.com/pulse/climat...

Climate "solutions" on my worst-dressed list: - Carbon capture and sequestration (including DAC) - Green hydrogen (for heat/fuel) - Regenerative agriculture (as a carbon store) - Fusion power (not scaled & competitive until 2080) - 90%+ of biofuels (ILU emisions)

Carbon capture schemes are being pushed by fossil fuel interests. Why? First, so they can benefit from tax credits and government funding. But mostly to slow down the energy transition and prolong our dependence on fossil fuels. Here are the receipts: www.sciencedirect.com/science/arti...

Just read a paper estimating an LCOE of €437 per MWh for a first generation magnetic fusion plants. No, I didn't forget the decimal point. That's staggeringly awful.

I agree that mainstream climate solutions reporting is really quite poor. It takes significant expertise to do critical reporting in this area and few journalists have this. Apart from solar PV and EV's, most climate solutions are under-performing vs. aspirations - some drastically (e.g DAC, CCS)

Just finished "We are eating the earth" by @mikegrunwald.bsky.social. Ambitious and breezy storytelling about agriculture emissions and climate. If you ever wanted to understand land use emissions - this is for you. Overall a great read - highly recommend.

The European Investment Bank (EIB) has just approved a €500 million loan for Eni's new biorefinery in Livorno. For the self-declared ‘EU climate bank’ this is a very questionable use of public money. 🧵⤵️

Why does Trump hate wind power so much? Because offshore wind is the only viable renewable option for the entire US NorthEast and the whole region currently heavily relies on fossil methane for building heat.

On-the-button piece by @hannahdaly.ie - this crazy HVO bandwagon must be stopped! "HVO is a climate ‘quick fix’ that could be worse than fossil fuels" www.irishtimes.com/environment/...

The goal of the fossil fuel lobby in the US is to make electricity as expensive as possible in order to defend the oil market for cars/trucks and the gas market for industrial and building heat. Expensive electricity is a goal, not an inadvertent side effect.
