Globally, carbon capture is making precious little progress. Is the Allam Cycle natural gas power plant an important step forward? David Yellen at the Atlantic Council Global Energy Center explains that, according to its designers, its energy conversion efficiency is 59%, 11% more than a standard combined-cycle gas turbine plant that’s carbon capture-equipped. It also captures 100% of the CO2, 10% more than the standard. NET Power plans to bring … [Read more...]
The outlook for Powerfuels in aviation, shipping
The development and commercialisation of powerfuels is in its very early stages. Powerfuels are synthetic gaseous and liquid fuels produced from green electricity. The plan is to use them when there is no viable alternative, like aviation and shipping. The big hurdle is cost, currently in the range of €3-5/litre, or five to ten times the price of fossil fuels. Dolf Gielen and Gabriel Castellanos at IRENA and Kilian Crone at the German Energy … [Read more...]
Stimulus opportunity: Hand all carbon taxes to households
Governments worldwide now have the opportunity to radically rethink how household consumption can be stimulated, and where that money can come from. And every serious politician knows a radical change in fiscal policy is a rare opportunity to shape perceptions and values. This could be that moment for carbon taxes. Gerard Wynn at IEEFA first notes the success they have had in reducing emissions in the EU. With a rise in the CO2 price on the … [Read more...]
Covid-19 and the EU car industry: any support should lock in EV targets
The coronavirus slump has come suddenly and hit hard. The deep thinking has already begun on the economics needed to turn around that slump without damaging our rising emissions ambitions. Julia Poliscanova at Transport & Environment looks at the car industry. Some have called for the new CO2 standards coming in 2020 to be postponed (though, notably, VW and BMW still support them). She explains that total car sales were already declining in … [Read more...]
Coronavirus bailouts should be explicit, not hidden by CO2 tax cuts. And nothing for Oil
Many industries will be pleading their case for a Coronavirus bailout. Severin Borenstein at the Energy Institute at Haas explains why the oil industry should not be one of them. Oil prices, already on the slide, are indeed sinking lower thanks to the pandemic. But decarbonisation should be sending them that way anyway. And the oil price has always be artificially high thanks to the OPEC cartel and weak or complicit “competition” from non-OPEC … [Read more...]
Construction emissions: “mass wood” prototypes halve CO2, rapid modular deployment, 18 stories
Building and construction emissions account for two-thirds of the global total, with one tenth coming from the construction phase alone. David Chandler at MIT reviews their research, in collaboration with a range of specialist companies, into wooden buildings. Their construction emissions should be as low as half that of concrete or steel. The key is the development of large scale, cross-laminated “mass wood”. Factory built modules can be … [Read more...]
How underground CCS works: low leakage risk, 2%
It’s not just the high upfront costs and the absence of a profitable business model that’s stalling the take-off of Carbon Capture and Storage (CCS). There are fears that CO2 stored underground will leak over the thousands of years it needs to be sequestered. The companies that put it there will be long gone. If you aren’t around to take the blame and pay the penalty, why bother doing it properly? Stephanie Flude at Oxford University and Juan … [Read more...]
EU Green Deal: meeting targets by lowering non-EU neighbour emissions too
The EU‘s Green Deal and its increasingly ambitious transition policies cannot be limited to its member states, writes Marc-Antoine Eyl-Mazzega at the IFRI Centre for Energy & Climate. For its emissions targets to be met in a meaningful way the EU needs to ensure its neighbours to the east and in North Africa follow. The danger is that carbon intensive industries simply shift to those neighbours, and their products get imported back in. … [Read more...]
Are national fossil fuel car bans compatible with EU laws, intra-trade, movement?
A growing number of EU nations are announcing laws to phase out the sale of new fossil fuel cars within the next 20 years. But are the proposed bans compatible with EU laws, or even workable given cross border trade and movement rights? If you are Dutch, why not buy your new petrol car in Belgium, then drive it back to the Netherlands? How do you enforce CO2 targets with foreign haulage fleets transiting through your nation? Eoin Bannon at … [Read more...]
Two new designs, GSR and MA-ATR, to make “blue” Hydrogen cheaper
What’s the best way to make clean hydrogen? Steam Methane Reforming (SMR) is the most common and cheapest way of producing hydrogen, but it also produces CO2 emissions. Capturing that CO2 is complex and costly. Schalk Cloete presents research on two new designs for “blue” hydrogen (blue = derived from natural gas/coal with carbon capture/CCS). He describes in detail Gas Switching Reforming (GSR) and Membrane-Assisted Autothermal Reforming … [Read more...]
Methane emissions underestimated by 25-40%, says new study
The methane in our atmosphere comes from natural biogenic (plants, animals) and fossil sources. By telling the difference we can know how much we humans are responsible for. It matters because methane is a potent greenhouse gas, second only to CO2. Previous “bottom-up” estimates came from multiplying the number of sources (livestock, natural gas operations, landfills) by their likely emissions. Robert McSweeney at Carbon Brief describes a new … [Read more...]
BP’s zero-carbon pledge: three major challenges
This month BP, one of the world’s largest oil and gas firms, announced its ambition to be a net zero emissions company by 2050. The promise extends to cutting the emissions of its customers too; after all, they’re the ones who are actually burning the fuel, not BP. So it aims to reduce the carbon intensity of its products by 50% by 2050 or sooner. Jules Kortenhorst, Tyeler Matsuo and Raghav Muralidharan at Rocky Mountain Institute take a look at … [Read more...]
Canada is launching methane emissions rules for Oil and Gas
January 2020 marked the first time the Canadian government has targeted methane emissions from the oil and gas sector. They’ve committed to reduce oil and gas methane emissions by 40% to 45% below 2012 levels by 2025. Reducing methane emissions is considered one of the most cost-effective ways to cut global emissions. Methane equates to around 5.4% of the country’s total emissions of 716 Mt CO2-eq. The IEA estimates global methane emissions from … [Read more...]
Germany must put CCS back on the table, says Merkel
Carbon Capture has not been popular in Germany. The public are largely opposed, political parties are split, and Federal States are not approving new projects. Germany has only four operations, and only one has injected anything (not much) into the ground. Now Chancellor Merkel wants it back on the table, along with a public debate. Julian Wettengel at Clean Energy Wire runs through the reasons for the opposition (an excuse to keep coal plants … [Read more...]
Norway’s “Northern Lights” project: creating the CCS business model
Northern Lights, a carbon capture and storage (CCS) project backed by the Norwegian government, is drilling test wells in the North Sea to find suitable places to store CO2. Project partners include Shell and Total, and others are joining them. CO2 will be shipped to an onshore terminal from which it is piped to the subsea wells. Once established, the plan is for other European countries to send their CO2 too. The project will also create the … [Read more...]
