  • This is really positive news especially as most the efficiency savings come from things that are only at the start of their roll-out, a lot of the infrastructure development for solar and wind is already in place with construction already in progress for huge amounts of generation. It likely also that the lower demand for electricity comes in part due to more efficient devices gaining market share; better water heaters, heat-pumps, LED lighting, etc combined with better insulation and more focus on efficiency - plus of course home solar or similar, an increasing amount of people are at least partly off-grid and use home generated power which reduces demand on the power grid.

    We also have some really useful new tech starting to reach market like tidal generation, tandem solar cells, Perovskite (which we’ve been hearing about for ages but they’re actually starting to build factories), e-fuels (again long heralded but actually starting to move into commercial production), and various new electric planes, boats, charging technologies, energy storage mediums, and etc all of which will help increase the rate of adoption and help decrease carbon emissions.



  • yeh this is a really promising technology and it’s not as far as most people seem to think from being widely adoptable, there are some great projects underway

    The CCH2 [Carbon Capture and Hydrogen production from Biomass, Kew Technology] Project will develop designs for additional modules which will upgrade this gas to produce separate high-purity Hydrogen and CO2 streams. The hydrogen can be sold for industrial / transport applications and the CO2 sent for sequestration (20,000 tonnes per year per module). The strong revenues from the hydrogen enable overall very low costs per tonne of CO2 removed and the financing of sustainable biomass supply chains in a circular economy providing multiple environmental and societal benefits including new rural and industrial jobs.

    basically you grow a load of plants (generally the excess biomass from crops and maintained spaces) and burn them (in this case through a gasification process that releases hydrogen also) the carbon which is released is then captured for storage or use, this can be especially useful when burning plants that have grown on toxic ground or polluted rivers as a way of absorbing all the bad stuff which is then trapped forever and returned to an old coalmine along with all the carbon that originally came from there.

    another interesting project that just got funding is DRIVE;

    Mission Zero has developed a new DAC technology that, at scale, is projected to have 75% lower costs and energy footprints than today’s commercial solutions and is suitable for both carbon utilisation and sequestration (CCUS) use cases. With engineering support from Optimus, the project will design Mission Zero’s 365 tons a year pilot plant in Phase 1. This will integrate with O.C.O Technology’s CCUS process which stores CO2 permanently while producing building aggregates from waste.

    using the captured carbon to make useful materials like building aggregates makes it far more likely systems will get adopted, especially if they get to a price point where they’re creating profitable items This is something a lot of people are working on

    [Cambridge Carbon Capture Ltd] aims to deliver a fully costed plan for a demonstrator capable of capturing CO2 from air and converting it directly into a mineral by-product with uses as construction materials using CCC’s CO2LOC carbon capture and mineralisation technology.

    Another really cool use of captured carbon has recently passed a loads of tests from the US Air Force who’ve worked with a company called Twelve on a project to create a viable jet fuel from CO2,

    E-Jet fuel is SAF produced using Twelve’s revolutionary carbon transformation technology, which uses only renewable energy and water to transform CO2 into critical chemicals, materials and fuels conventionally made from fossil fuels, and in partnership with Emerging Fuels Technology. As a power-to-liquid SAF with up to 90% lower lifecycle greenhouse gas (GHG) emissions compared to conventional, petroleum-based jet fuel, E-Jet fuel meets the applicable ASTM International specifications and is a drop-in ready synthetic fuel that works seamlessly with existing aircraft and airport infrastructure. It faces no real constraints on feedstock, thus offering the best viable long-term solution for addressing GHG and other emissions from the aviation sector.

    the test facility they’re currently building isn’t going to produce much but it’s a huge first step on the way to industrialisation of the technology,

    The facility is expected to begin E-Jet fuel production in mid-2024 at a capacity of approximately five barrels per day (40,000 gallons per year), with plans to quickly increase production capacity.

    that’s only about 0.00007% of the Jet Fuel used per year, but if they refine the system and make one which can be built at any airport using power from onsite renewables then it’s likely we’d see a very rapid adoption.




  • it’s not entirely irrational though, if you’re convinced you’re in a frying pan and doom is imminent then it can feel like your only option is to jump out into the fire - and maybe it will work out better, maybe we’d land on a recently added log and spring to safety… personally i’m more about doing some parcour out the pan and along and the wooden handle or jumping onto the hand holding the spatula and burning through the flesh of the beast that got us into this dire situation.

    By that i of course mean developing a powerful open-source movement and an educated community which is able to transition to better ways of living without hurting anyone, it’s harder and far more complex but something we absolutely must strive for.




  • ok play it through a bit, so we shut down those 7 companies - i’m not sure which seven companies people are talking about but i assume it’s related to this statistic Just 100 companies responsible for 71% of global emissions so let’s just shut them all down…

    mother nature breaths a sigh of relief as billions of people die because of the collapse of global infrastructure, world governments collapse, desperate conflicts erupt around the world with warlords taking over oil reserves and production facilities… the handful of dictators with working tanks and who only care about wealth and power subjugate the helpless and starving masses promising food and prosperity when victory comes…

    Now the planet has been purged of everyone who actually cares about the climate, every available source of food and energy is stripped in a frantic battle for survival - how many people do you know that would let their kids freeze to death and how many people do you know that’d go out and chop down a tree to burn? A couple of months of winter and every tree in every city would be felled.


  • also we need communities already experimenting with living like that or it’ll be a mess, for example I’ve never eaten meat in my life and as a kid people couldn’t even begin to grasp that it was possible - i’d constantly get asked ‘what do you eat then?!’ but I haven’t heard that question in years, closest to it is likely to be ‘what do you have at Christmas’ then when i say nut roast they no long say ‘whats that?’ they say ‘oh i had a great nut roast once…’

    As a kid family holidays used to involve stopping at the only cafe that had something without meat on the menu, now even McDonalds has a wide vegan selection (in the uk). If someone had come out in the 80s and ended the meet subsidies then it would fail instantly, if it happened now there would certainly be a large backlash but the majority of people would be able to shift their consumption patterns without many problems - the policy might have a fighting chance. Even the meat-and-two guys that i know regularly have meet free dinners, it’s really common to only eat meat once or twice a week.

    Of course if i was made dictator for life i’d bring in sweeping changes that ban all the evil practices which make the meat industry possible, but that’s not going to happen - what is going to happen is it’s going to continue to get easier and cheaper to eat plant based diets, we’re going to see endless headlines like ‘largest dairy producer announces closure amid increasing popularity of oat milk’, it’ll shift from the beef industry having a hugely powerful lobby backed by billions of dollars to the beef lobby being Joe Rogan and Liverking yelling at clouds about how they need to consume flesh to feel manly. When someone suggests banning an awful and disgusting practice within the meat industry the general consensus will be ‘yeah i can go without that if it’s damaging to the environment and cruel to the animals’ so policy change will actually be possible.

    Just shrugging and saying ‘it’s not going to happen overnight so i’ll just keep eating meat until it does’ is absolutely mindless, the bath is never going to fill if the tap isn’t turned on - eating without meat helps fund and sustain the systems which makes it possible, it helps make it easier for other people to also eat without meat – even if it’s only dropping meat where it’s convenient it’s helping take power from the meat industry, by making a conscious choice to avoid meat you’re joining an increasing number of people who do the same which represents a sizeable portion of the market - the more that gets catered to the large it grows.

    Yes it’s true that no one person is going to change things but when we start to move in the right direction it makes it easier for others to move that way also. This is the same with reusable bottles, using public transport, refilling containers at the store instead of single use plastics…
