    1. excessive expectations and reliance on CCUS
      • for: quote - Carbon Capture expectations - unfeasible

      • quote

        • If oil and natural gas consumption were to evolve as projected under today’s policy settings, this would require an inconceivable 32 billion tonnes of carbon captured for utilisation or storage by 2050,
          • including 23 billion tonnes via direct air capture to limit the temperature rise to 1.5 °C.
        • The necessary carbon capture technologies would require 26 000 terawatt hours of electricity generation to operate in 2050,
          • which is more than global electricity demand in 2022.
        • And it would require over USD 3.5 trillion in annual investments all the way from today through to mid-century, which is an amount equal to the entire industry’s annual average revenue in recent years.

    1. The key benefit and primary motivation for installing hydrogen fuel cells within a data center is to reduce carbon emissions. As stated, some fuel cells, such as SOFCs, can use natural gas. While it is less damaging to the environment than diesel, it still results in significant carbon emissions.

      Is this some of the missing context for the CCS next to datacentre patents from M$?

      If you can capture the CO2, and use the waste heat to separate the CO2 from the absorbing material, then it might improve the economics of the SOFC fuel cells, AND deal with the CO2 emissions problem.

    1. Carbon capture is a phishing scheme introduced by the Koch brothers at MIT in 2004, the same year that Charles and David Koch provided the funds for Americans for Prosperity.

    1. So what can we make of politicians who continue to argue that ‘1.5°C is still alive’? Are they misinformed or are they simply lying?I believe many are in denial about the types of solutions the climate crisis demands. Rather than do the – admittedly – very difficult political work of eking out our supplies of fossil fuels while accelerating a just transition to post-carbon societies, politicians are going all out on technological salvation. This is a new form of climate denial, which involves imagining large-scale carbon dioxide removal that will clean up the carbon pollution that we continue to pump into the atmosphere. While it may seem much safer to stick to the script and say that it is still physically possible to limit warming to no more than 1.5°C, while pointing out that the scale of change demands much more political will, I believe that this can no longer be a credible response to the climate crisis.We have warmed the climate by 1.2°C since pre-industrial periods. If emissions stay flat at current levels, then in around nine years the carbon budget for 1.5°C will be exhausted. And, of course, emissions are not flat – they are surging. 2021 saw the second-largest annual increase ever recorded, driven by the rebound in economic activity after Coronavirus lockdowns. We did not ‘build back better’.The clock has been stuck at five minutes to midnight for decades. Alarms have been continuing to sound. There are only so many times you can hit the snooze button.

      Going all out on technological salvation is a form of climate denialism.

      We are at 1.2 Deg C and emissions have climbed after rebounding after Covid. If they flatline for the next nine years, we will hit 1.5 Deg C.
