As always, the energy world is abuzz with reactions to the IEA’s annual World Energy Outlook, published yesterday. As always, it’s getting plenty of criticism from those who say it lacks ambition, and in doing so will again get quoted to justify support for continued reliance on fossil fuels, explains Kelly Trout at Oil Change International. The IEA’s most ambitious pathway, the Sustainable Development Scenario (SDS), gives a 66% chance of … [Read more...]
10 Carbon Capture methods compared: costs, scalability, permanence, cleanness
We need to understand carbon capture, storage and utilisation (CCUS) better. To do so, this article looks at 10 methods and estimates how much CO2 each will take out of the atmosphere by 2050, and the cost per tonne. In their list the authors, Ella Adlen and Cameron Hepburn at the University of Oxford, cover the industrial (e.g. CO2-EOR, synfuels) to the biological (e.g. forestry, soil carbon sequestration). They say there are six that can be … [Read more...]
China’s industry: Deep decarbonisation progress and challenges
Across the world, industry is regarded as a hard-to-decarbonise sector, and an emissions priority. In China it’s responsible for over 65% of its energy consumption and 70% of carbon emissions. Ji Chen and Shuyi Li of the Rocky Mountain Institute (RMI) look at the highlights of China’s efforts, and reference them against the RMI’s Reinventing Fire: China analysis. Efficiency, electrification, CCUS, hydrogen and “recycle and reuse” all play an … [Read more...]
The Clean Hydrogen revolution: how, by whom, when?
Hydrogen rivals oil and gas for storage and hard-to-decarbonise sectors (industry, heavy and long distance transport). But it isn’t all carbon free. “Grey” hydrogen – the cheapest at €1.50/kilo - is made from gas. “Blue” hydrogen depends on the fortunes of carbon capture technology. “Green” hydrogen is CO2 free, but needs further cost reductions in the green electricity used in the electrolysis process. Noé van Hulst, at the Netherland’s Ministry … [Read more...]
UK’s net-zero ambition: counting all emissions, not just in-country
The UK’s Committee on Climate Change (CCC) has advised its government to go zero-carbon by 2050. But, say Joe Blakey and Marc Hudson of the University of Manchester, counting all emissions means counting the carbon footprint of imports too. Including these (and excluding emissions from exports) the UK’s footprint is 70% higher than the figure used by the CCC. The same is likely true for all high income economies. And the cost of successful … [Read more...]
Carbon Capture: Can CO2-EOR really provide carbon-negative oil?
Enhanced Oil Recovery (EOR) injects CO2 into oil reservoirs, increasing the pressure and forcing the oil out. 20% of global oil production uses EOR. But if that CO2 doesn’t stay underground it hasn’t been captured. If it was itself extracted from natural underground CO2, there is no benefit – or worse. Ideally, it should come from already captured CO2. But most oil wells are nowhere near a CCUS (carbon capture, usage and storage) facility: in the … [Read more...]
