    XCHAOS: no tech power to gas/liquid reseni je vic. taky jsou redox flow baterky na velky kapacity.

    vodik v sobe ale ma obrovskej power, takze je idealni do prumyslu, letecky, lodni dopravy apod.

    prekazkou na masovy pouziti je uz jen efektivita konverze a na tom spousta lidi pracuje. nedavno sem sem nebo do vedeckyho auditka daval link na novou membranu s daleko vyssi ucinnosti

    SHEFIK: jo, no to zato my jsme pašáci, my snižujeme spotřební daň na naftu :-)

    "vodíkové ekonomice" ve smyslu těch vlaků a náklaďáků - teda moc nevěřím, tam prostě převládnou baterie, i kvůli rekuperaci. Ale stacionární úložiště vodíku asi smysl dává, je to v podstatě jediné sezónní úložiště, které umíme (je tam spousta odpadního tepla, z těch palivových článků, takže by to dávalo smysl jako náhrada uhelných elektráren, s využitím existujících teplovodů)

    Wildfires blazed along the Arctic Circle this summer, incinerating tundra, blanketing Siberian cities in smoke and capping the second extraordinary fire season in a row. By the time the fire season waned at the end of last month, the blazes had emitted a record 244 megatonnes of carbon dioxide — that’s 35% more than last year, which also set records. One culprit, scientists say, could be peatlands that are burning as the top of the world melts.

    Peatlands are carbon-rich soils that accumulate as waterlogged plants slowly decay, sometimes over thousands of years. They are the most carbon-dense ecosystems on Earth; a typical northern peatland packs in roughly ten times as much carbon as a boreal forest. When peat burns, it releases its ancient carbon to the atmosphere, adding to the heat-trapping gases that cause climate change.

    Global Safety Net
    https://www.globalsafetynet.app/

    The first global-scale analysis of land areas requiring protection to solve the twin crises of biodiversity loss and climate change.

    ...

    More than two years in development, the Global Safety Net is the first comprehensive global-scale analysis of terrestrial areas essential for biodiversity and climate resilience, totaling 50.4% of the Earth's land. The report was published in Science Advances and highlights the importance of protecting and restoring the natural world to address three converging crises -- climate change, the loss of biodiversity, and the emergence of novel viruses such as COVID-19.

    The research team was led by the research organization RESOLVE in collaboration with the University of Minnesota, Arizona State University, and Globaïa, with funding provided by One Earth. The data compiled for the Global Safety Net (GSN1) is available through an interactive web application (GSNapp) developed by One Earth in partnership with Google Earth Engine and the data visualization firm Graphicacy. Users can click on a country, state, or ecoregion to see configurations of biologically important land for each region.

    The research effort builds upon an array of global-scale data sets to identify areas that require conservation beyond the 15.1% of land area currently protected. These are compiled into five main layers at a 1 km resolution: Species Rarity Sites, High Biodiversity Areas, Large Mammal Landscapes, Intact Wilderness, and Climate Stabilization Areas.

    Why Poland is finally giving up its dirty coal habit - Electrek
    https://electrek.co/2020/09/10/why-poland-is-finally-giving-up-its-dirty-coal-habit/amp/

    Poland generates a huge 74% of its electricity from coal — second only to Germany in Europe, and it’s the ninth-largest coal producer in the world. It has been the only country in the European Union to refuse to agree to reach net zero by 2050. It claimed it needed more time and money to make the shift.
    But its hand has been forced by the rising costs of emissions permits required by the European Union’s cap-and-trade system, the EU’s other increasingly ambitious climate policies, and the pandemic, which caused a fall in the use of power. Reuters reports:

    In an update of its energy strategy by 2040, the climate ministry said Poland plans to invest 150 billion zlotys ($40 billion) to build its first nuclear power plants, with 6-9 GW of capacity eventually. The first 1-1.6 GW facility would be up and running by 2033.
    It also plans to build 8-11 gigawatts (GW) of offshore wind capacity by 2040 with investment estimated at 130 billion zlotys ($35 billion). The development of renewable and nuclear energy facilities will create 300,000 jobs, it said.

    The climate ministry said that coal’s share in electricity production will fall to 37%-56% in 2030 and to 11-28% in 2040, depending on the carbon emission costs.

    Compare this to November 2019, when Poland had expected the share of coal at 56%-60% in 2030 and at 28% in 2040.

    France wants 6.5 GW of hydrogen capacity by 2030 – pv magazine International
    https://www.pv-magazine.com/2020/09/10/france-wants-6-5-gw-of-hydrogen-capacity-by-2030/

    The ministers reminded their audience the hydrogen strategy has been allocated €7.2 billion to 2030 under the France Relance plan, including €2 billion up to 2022.

    The government defined three hydrogen priorities. Firstly, it wants to decarbonize the industry with a pathway to electrolysis for carbon-free fuel, rather than the generation of hydrogen from fossil fuels. In line with that aim, France will launch an Important Project of Common European Interest for hydrogen similar to the European sustainable battery manufacturing ambition. “This, notably, involves the planning of gigawatt-sized electrolyzer projects in France, according to a scheme similar to the battery plan which provides for the development of the Nersac and Douvrin factories by ACC, a joint venture of [carmaker stable] PSA and [energy company] Total/[and battery subsidiary] Saft (soon to be joined by Renault),” the hydrogen strategy stated.

    The second priority is the development of hydrogen-fueled public transport and commercial goods vehicles – including trains and bin lorries – across large territories. A €350 million tender for innovative projects in that area will be held this year and a €275 million exercise has also been planned to procure ‘innovative large-scale industrial ecosystem’ facilities. The latter, which will attempt to encourage economies of scale, will be conducted by the Environment and Energy Management Agency.

    Can A New Kind Of Capitalism Effectively Confront The Climate Crisis?
    https://cleantechnica.com/...0/can-a-new-kind-of-capitalism-effectively-confront-the-climate-crisis/

    McAfee is a principal research scientist at the Massachusetts Institute of Technology who focuses on digital transformation. He says that today’s environmental degradation and growing inequality, which were originally grounded in colonialism, can be held in check by what he calls the “four horsemen of the optimist,” namely:

    - capitalism
    - technological progress
    - public awareness
    - responsive government

    He says we can’t let one of these “horsemen” overpower the others. If it is in capitalism’s nature to increase inequality, then a responsive government should reign in that excess. If capitalists have incentives to shape regulations to maximize their profits, the government should legislate in ways that ensure equity for all.

    Humans exploiting and destroying nature on unprecedented scale – report | Environment | The Guardian
    https://amp.theguardian.com/...ns-exploiting-and-destroying-nature-on-unprecedented-scale-report-aoe

    Robin Freeman, who led the research at ZSL, said: “It seems that we’ve spent 10 to 20 years talking about these declines and not really managed to do anything about it. It frustrates me and upsets me. We sit at our desks and compile these statistics but they have real-life implications. It’s really hard to communicate how dramatic some of these declines are.”

    Tanya Steele, chief executive at WWF, said: “We are wiping wildlife from the face of the planet, burning our forests, polluting and over-fishing our seas and destroying wild areas. We are wrecking our world – the one place we call home – risking our health, security and survival here on Earth.”

    Mike Barrett, executive director of conservation and science at WWF, said: “Urgent and immediate action is necessary in the food and agriculture sector. All the indicators of biodiversity loss are heading the wrong way rapidly. As a start, there has got to be regulation to get deforestation out of our supply chain straight away. That’s absolutely vital.”

    Animal Populations Fell by 68% in 50 Years and It’s Getting Worse
    https://www.bloomberg.com/...e-change-and-food-businesses-are-driving-environmental-failure-globally

    The world is losing its mammals, birds, amphibians, reptiles and fish, and with them, the security of ecosystems that have supported humanity since it first emerged.

    That’s the conclusion of the Living Planet Report 2020, a biannual assessment by World Wildlife Fund and the Zoological Society of London, which records the decline in vertebrate life. This year’s report, released Wednesday, shows that these animal communities shrunk on average 68% between 1970 and 2016. Parts of the world are much worse off. The tropical Americas have seen animal populations decline 94% in the same period. The size of observed animal communities in or near freshwater globally have fallen by 84%.

    The authors put half the blame on changes to how we use land and the sea, citing such things as clearing ecologically important forest and freshwater use. Overfishing and hunting, invasive species, pollution and climate change round out the main causes of the global animal population crash.

    The report delivers a tough overall message. It suggests that continued human abuse of the planet may lead to collapse of the very natural systems and resources that allowed global civilization and modern societies to persist in the first place. And, they say, humanity is demonstrably to blame, and the damage is unprecedented in speed and vastness within human history.
