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...]
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...]
Gas infrastructure leaks methane: fix it, or accelerate to clean energy
Natural gas, because it’s low-carbon, is being used as a bridge fuel away from the old fossil fuel world. But there are two main problems. The infrastructure leaks methane (the main component of the gas) which is 25 times more potent than CO2 over a 100-year period (and 86 times over a 20-year period!). And, crucially, nobody is properly measuring those leaks. That means policy makers are growing the gas mix without knowing by how much it’s … [Read more...]
Fossil fuel politics is changing: Big Oil, automakers split on Trump lowering standards
Cara Daggett at Virginia Tech has noticed a positive change in corporate support for the Transition. In the past, Big Oil and automakers would have opposed any limits to business-as-usual. But today, major oil companies, including BP and Royal Dutch Shell, are opposing U.S. President Trump’s intention to further deregulate methane emissions. That’s because they’ve invested heavily in natural gas as a bridge fuel for a clean future, which would … [Read more...]
New gas-to-methanol technology OxE could end oil well “flaring”
Oil wells also release natural gas. But it’s burnt off on site whenever the economics of collecting and piping it don’t add up (gas can’t use the existing petroleum infrastructure). What if it could be converted into methanol, says Nichole Liebov at the University of Virginia. She describes a new process called oxyesterification (OxE) that converts methane (the main constituent of natural gas) into methanol cost effectively at low temperatures … [Read more...]
IEA clean energy progress report: Only 7 technologies/sectors on track, 38 not
Of the 45 energy technologies and sectors assessed in the IEA’s latest Tracking Clean Energy Progress (TCEP) report, only 7 are on track with the IEA’s Sustainable Development Scenario (SDS). It’s their latest and most comprehensive assessment of clean energy transitions. “On track” includes energy storage, EVs and solar PV. But buildings, car, flaring and methane emissions are still rising. This year’s TCEP puts much greater emphasis on … [Read more...]
