    TUHOKlimaticka zmena / Thank you so much for ruining my day


    "Given the sheer enormity of climate change, it’s okay to be depressed, to grieve. But please, don’t stay there too long. Join me in pure, unadulterated, righteous anger."


    "I don’t want your hope. I don’t want you to be hopeful. I want you to panic. I want you to feel the fear I feel every day. And then I want you to act. Once you start to act, the hope is everywhere."

    "Our best scientists tell us insistently that a calamity is unfolding, that the life-support systems of the Earth are being damaged in ways that threaten our survival. Yet in the face of these facts we carry on as usual."

    “We’ve got to stop burning fossil fuels. So many aspects of life depend on fossil fuels, except for music and love and education and happiness. These things, which hardly use fossil fuels, are what we must focus on.”

    A nejde o to, že na to nemáme dostatečné technologie, ty by na řešení použít šly, ale chybí nám vůle a představivost je využít. Zůstáváme při zemi, přemýšlíme až moc rezervovaně. Technologický pokrok to sám o sobě nevyřeší. Problém jsme my, ne technologické nástroje.

    Rostouci hladiny oceanu, zmena atmosferickeho proudeni, zmeny v distribuci srazek a sucha. Zmeny karbonoveho, fosforoveho a dusikoveho cyklu, okyselovani oceanu. Jake jsou bezpecnostni rizika a jake potencialni klady dramatickych zmen fungovani zemskeho systemu?
    Ale take jak funguji masove dezinformacni kampane ropneho prumyslu a boj o verejne mineni na prahu noveho klimatickeho rezimu post-holocenu.

    Europe's Leaked Hydrogen Strategy Is Very Ambitious | OilPrice.com
    https://oilprice.com/...y/Energy-General/Europes-Leaked-Hydrogen-Strategy-Is-Very-Ambitious.amp.html

    in a recent Tracking Energy Integration 2020 report, the IEA calls hydrogen one of several integration technologies that are ‘increasingly crucial’ for a low-carbon energy transition. The report notes that important political momentum had been building through last year, listing ten international initiatives and national plans that appeared during 2019. These include top level G20 discussions and target-setting plans by Korea, Japan, Netherlands, Australia and Canada.

    Clearly the hydrogen movement is at a critical moment when continuing innovation is required. The role of government will remain important as fledgling industries seek to gain scale and find markets. Governments will need to provide direct, targeted support for projects that can achieve technical and market advances. And they will need to help stimulate demand in sectors where good near-term opportunities appear.

    ...

    The shifting emphasis can be seen especially in Northern Europe, where large concentrations of projects are now found. Renewable energy will power electrolysers to produce hydrogen for industries in northern industrial centers. Other projects focus on power and heat for urban districts. Key applications include large-scale electrolysis, carbon capture, utilization and storage (CCUS), and utilization of natural gas networks.

    ...

    In Germany, a power-to-gas project in Emsland in the Ruhr region has been called ‘Hybridge’ for its capacity to couple electric and gas networks. In a partnership of transmission system operator Amprion and gas net operator Open Grid Europe (OGE), electricity from renewable energy will be converted, by means of electrolysis, into hydrogen and methane. The companies will deploy a 100 MW electrolyser, with the resulting hydrogen transported by an OGE hydrogen pipeline and the existing gas pipeline network throughout the Ruhr and beyond. The project is anticipated to start operation in 2023.

    In France, in the Les Hauts de France region around Dunkirk, one of the world’s most ambitious power-to-gas projects will build five 100 MW hydrogen electrolyser production units over five years. The project, a partnership of France’s H2V Industry and Norway’s HydrogenPro, will introduce hydrogen into the natural gas distribution network in order to decarbonize the natural gas used for heating and cooking as well as for transport.

    These ambitious European projects have large-scale electrolysis counterparts in North America. Most notable is a project of the British Columbia-based Renewable Hydrogen Canada (RH2C), which is backed by a private sector utility and investors. The company is planning to build a large electrolysis plant in BC, to produce renewable hydrogen through water electrolysis powered by local hydropower and winds off the Rockies.

    ...

    An enormous pilot project to convert the gas networks to hydrogen in the north of England is being planned now. First announced in 2016, the H21 North of England (H21 NoE) project, is a collaboration of two British gas distributors, Northern Gas Networks and Cadent, and Norway’s Equinor (formerly Statoil). They have produced a hydrogen blueprint that will utilize the existing natural gas distribution infrastructure serving a region of 5 million inhabitants including several large cities for domestic and industrial users, with applications including heat, power and transport.

    The project’s planners view it as a way to achieve the ‘deep decarbonization’ that could not be reached with renewable electric power alone. To do so will require carbon capture and storage (CCS). Equinor’s role is to build a hydrogen production facility utilizing a standard reforming process with natural gas. The captured CO2 will be transported offshore to undersea storage. A specially built hydrogen transmission pipeline will link to the local gas distribution networks. The new transmission pipeline is required because injecting hydrogen into gas transmission pipelines is more difficult (although Italy’s Snam has already demonstrated the feasibility of blending hydrogen up to 10% in gas transmission grids).

    Project implementation is to occur between 2028 and 2034. It is anticipated to achieve deep decarbonization of 14% of the UK's heat demand by 2034. Its large scale and significant impact on carbon emissions will make H21 NoE the world’s first at-scale hydrogen economy. Should it succeed, it will lay a basis for expanding such a system across the entire UK, decarbonizing a large percentage of domestic heat, transport and power by 2050

    Hy2green - Das Energiespeicher-System für natürliche Energiequellen : Hy2green
    https://www.hy2green.com/

    Hydrogen is generated from electrical energy by means of electrolysis and fed into storage tanks filled with metal powder. Here, the hydrogen enter into the metal structure and remains as a safe and stable compound – which is known as metal hydride. This compound can be released again by simply adjusting the pressure and temperature. The released hydrogen is fed into a fuel cell and converted back into electricity and heat. The only residues are oxygen and water – natural elements and no environmental pollution!

    The integrated heat management system captures the conversion energy that is lost as heat and makes it available to the application’s heat cycle. This significantly increases the energy efficiency of the entire system.

    The result: An efficient zero emission electrical and thermal power system.

    ...

    The Hy2Green system covers energy storage ranges from 80 kWh to 66MWh and can be tailored to the application need. Its modular system approach offers a perfect integration of short term (day-night) storage types (e.g. electric batteries, hot water accumulators) enabling highest system flexibility.

    Vybouchne vlivem tání permafrostu krom tý ropy taky nějaká jaderná elektrárna? Nebo se pohyb podloží u jaderných elektráren zohledňuje?

    BROZKEFF: tak tomu docela rozumím, nechtěl jsem vědět, že to bude 25. července 2047. Spíše mě zajímal horizont, že se s tím počítá třeba v rámci další 30 let, že to bude mít už zásadní vliv, mluvilo se o tom, že by to mohla být naše deadline

    LINKOS: to se už děje, a ne, není to binární proces "je permafrost" x "není permafrost". Všechno asi nejbližší stovky/tisíce let neroztaje, ale to ani není potřeba, jen z z těch pár metrů co roztajou to může uvolnit metanu víc než dost. Kromě té Shakhove co to systematicky studuje posledních 10-15 let minimálně co se týče viditelných publikací ale k permafrostu a potenciálu kolik to může metanu uvolnit a jak masivní to je feedback loop se moc neví, protože systematických dat je málo. Proto to ani IPCC report prakticky nezohledňuje, protože nemá "dost tvrdá" data. (Nejsou data? Jev neexistuje.) Ale pokud ty locking patterny jetstreamu budou jako teď kdy nám tu měsíc v kuse prší a je relativně zima, zatímco na Sibiři mají měsíc v kuse třicítky vedra, tak se to tomu permafrostu líbit nebude. Nowaco bude mít ztrátu z toho že mu zhnijou mražení mamuti, co si tam archivuje.

    DRSH: zrovna jsem koukal na nějaký mapy intersucho.cz a fak ty deště začaly za 5 minut 12...

    Jestli jsem to správně pochopil - ono to trochu taky záleží na interpretaci - tak už minulou neděli tj 14.6 byla situace v hloubce 0-40cm velmi dobrá (dá se teda předpokládat že zítra - kdy se to vyhodnocuje) bude ještě mnohem lepší...

    Problém je hloubka 40-100cm, tam je to sice vzhledem k nějakým posledním standardům taky docela dobrý, ale potřebovalo by to být mnohem lepší...

    Je třeba říct, že od neděle odpoledne se má otočit počasí a začít horko. Takže se dá čekat že co ta hlubší vrstva do zítřka nasákne, to nasákne a pak už bude jen ztrácet

    Scientists’ warning on affluence
    https://www.nature.com/articles/s41467-020-16941-y

    Any transition towards sustainability can only be effective if far-reaching lifestyle changes complement technological advancements. However, existing societies, economies and cultures incite consumption expansion and the structural imperative for growth in competitive market economies inhibits necessary societal change
    Many of these studies employed multiple regression or similar techniques, yielding clear evidence for our first finding: that consumption is by far the strongest determinant of global impacts, dwarfing other socio-economic–demographic factors such as age, household size, qualification or dwelling structure12,
    The majority of studies agree that by far the major drivers of global impacts are technological change and per-capita consumption11. Whilst the former acts as a more or less strong retardant, the latter is a strong accelerator of global environmental impact. Remarkably, consumption (and to a lesser extent population) growth have mostly outrun any beneficial effects of changes in technology over the past few decades.
    Since the level of consumption determines total impacts, affluence needs to be addressed by reducing consumption, not just greeninneeds,the strongest pillar of the necessary transformation is to avoid or to reduce consumption until the remaining consumption level falls within planetary boundaries, while fulfilling human needs
