In May the U.S. Environmental Protection Agency proposed new rules regulating carbon emissions from fossil fuel-fired power plants. Here, four experts from the Center for Strategic and International Studies â Cy McGeady, John Larsen, Kyle Danish and Mathias Zacarias â make their assessment and point at the wide-ranging implications. The main issues covered include CCS, hydrogen-fuelled generation, state clean energy standards, carbon pricing, … [Read more...]
Financing Renewable Hydrogen globally: ramp up to 2030 only needs $150bn/year
Dolf Gielen, Priyank Lathwal and Silvia Carolina Lopez Rocha at the World Bank present a thorough review of the pathway to financing global clean renewable hydrogen over the coming decades. The wind and solar that powers production will continue to get cheaper, and so will electrolyser costs as they scale up. Nevertheless, the total financing will still be considerable. World Bank analysis shows around $30tn between now and 2050 will be needed … [Read more...]
Five charts on the Energy Transition: the 2020s is the decade of maximum disruption. By 2030 the endgame will be clear
Sam Butler-Sloss and Kingsmill Bond at RMI present a succinct summary of why the energy transition matters, how the 2020s is the era of maximum disruption, and how by 2030 the transitionâs endgame will be apparent (though far from complete). Four key technologies are already entering the exponential growth stage: solar, wind, EVs and heat pumps. As early as 2030 their cheapness will flush away the fossil equivalents in succeeding decades, say the … [Read more...]
Making Hydrogen direct from seawater using double-membrane electrolysis
Can hydrogen be produced from seawater? The standard method requires water to be purified, which is expensive to do and adds complexity to the device. David Krause at the SLAC National Accelerator Laboratory, Stanford University describes new research there that uses electrolysis and a double membrane directly on the seawater to separate out the chloride and isolate the hydrogen and hydroxides. The system operates without generating toxic … [Read more...]
The history of evidence of CO2-driven climate change starts in the mid-1800s
Marc Hudson at the University of Sussex gives us a fascinating review of the history of climate change science. While the Intergovernmental Panel on Climate Change (IPCC) was established in 1988, experimental evidence that CO2 traps heat dates back to the mid-1800s. The first predictions of global warming caused by humans came in 1895. The big change in perception took place in 1953. Canadian physicist Gilbert Plass (an academic whose career also … [Read more...]
Oil & Gas can meet 2030 net-zero target for only $600bn, quickly recouped. But itâs still not happening, warns IEA
The IEA summarises its 33-page report âEmissions from Oil and Gas Operations in Net Zero Transitionsâ. The IEA says the oil and gas sector needs ÂŁ600bn up front to meet its 2030 target of a 60% reduction in emissions. Thatâs only 15% of the sectorâs record 2022 energy-crisis windfall income. A small price increase and savings should recoup that money âquicklyâ, says the IEA. The IEA not only maps a way to limit the global average temperature rise … [Read more...]
Global âexplosiveâ growth means 1 in 3 new cars will be electric by 2030. But SUV emissions could wipe out those gains
More than a third of all new vehicles sold globally in 2030 will be electric, according to the IEA. Thatâs a doubling of its prediction made only two years ago. Josh Gabbatiss at Carbon Brief summarises the report. The IEA describes the growth as âexplosiveâ: from just 1% of global car sales in 2017, to 14% last year, and now 18% expected by the end of 2023. China has consistently dominated those sales while new policies in the U.S. and EU are … [Read more...]
How can Europe stop U.S. and China dominance of cars and batteries without being protectionist?
European and Chinese car and battery makers are making plans to set up plants in the U.S. to take advantage of their big new âmade in the USAâ subsidies. They can then ship their vehicles to Europe to sell into its very large and generously subsidised company car market. This puts electric vehicle production in Europe at a serious disadvantage. As William Todts at T&E explains, the EU must respond, instead of effectively assisting the U.S. … [Read more...]
âExascaleâ computing algorithms can deliver new Wind Turbine designs and on-site power-maximising strategies
Advances in exascale computing algorithms and models for multiscale atmospheric flows are leading to new wind turbine designs and on-site power-maximising strategies previously not possible, explains Brooke Van Zandt at NREL. The models can contain and process two billion grid points, simulating the air flow around turbines in a large wind farm with unprecedented accuracy. Van Zandt describes how the new tools are being used to deal with highly … [Read more...]
EU Carbon Removal Certification Framework: new rules to turn greenwashing into genuine removals
The EU Carbon Removal Certification Framework intends to drive forward technological and natural carbon removals, and prevent greenwashing through robust standards and certification procedures. Itâs to deal with the existing poorly monitored carbon removals market: the lack of oversight, transparency, trustworthiness, and genuine climate impact (additionality) of projects and certificates. Simon Göss at carboneer looks at the current proposals, … [Read more...]
âRebound Effectâ: cheap LEDs mean more lights everywhere. But brighter homes, offices and public spaces are worth having
LEDs are 90% more efficient than modern incandescent bulbs. Their rapid uptake has resulted in measurable cuts in energy demand and emissions. But their plummeting cost over the last ten years is also causing a ârebound effectâ where people are using more and more LEDs, not least for outdoor lighting. Lucas Davis at the Haas School of Business believes we must embrace it, even if itâs counter to maximising energy savings. More and brighter … [Read more...]
Europe: preventing a âcarbon wallâ between the West and the ten Central and Eastern EU nations
Diana-Paula Gherasim at the IFRI Centre for Energy & Climate summarises her 36-page data-rich report on the progress and challenges for the ten Central and Eastern EU (CEECs) countries in decarbonisation. The Russian invasion of Ukraine has focussed all minds on energy security and the best solutions: less fossils, efficiency gains and clean energy made in the EU. Gherasim says that vitally important progress is being made in avoiding a … [Read more...]
CO2 emissions from Land Use: country-level data for turning âemittersâ into âsinksâ
Until carbon capture technologies take off (if at all!), the worldâs CO2 removals depend entirely on nature. Clemens Schwingshackl, Wolfgang Obermeier and Julia Pongratz at Ludwig Maximilian University of Munich, writing for Carbon Brief, review the latest data on âcarbon fluxesâ which measure whether the land is a net âsourceâ of carbon or a âsink.â Flux measurements are categorised: deforestation, forestation, wood-harvest emissions, removals … [Read more...]
Can Phytomining deliver Critical Minerals at scale: farming plants that accumulate high metal concentrations
Both Europe and the U.S. are making plans to secure supplies of critical minerals as the transition gains pace. Domestic mining or securing import deals with close allies is the main focus. Here, Maria Krol-Sinclair and Thomas Hale at CSIS review the prospects for a new method that will require neither: phytomining. Some plants, called hyperaccumulators, soak up high concentrations of metals into their leaves, bark, and roots. These plants can … [Read more...]
Green District Heating: can the energy crisis + new carbon targets drive new investment?
Rebecca Pool, writing for ESCI, describes green district heating projects where the operator is a âmiddle manâ between new energy generators (waste heat, renewables, etc.) and end users. The energy crisis has created an opportunity, as unpredictable gas prices combined with new carbon targets have made the long-term investment more attractive. But district heating is in direct competition from heat pumps and natural gas, so it needs to be price … [Read more...]
