With the adoption of REDIII last week we are set for a dramatic increase in the “renewable” element of liquid fuels. It means that in just 10 years, the renewable element will have tripled, rising from 10% in 2020 to 29% from 2030 onwards. In the EU, Concawe (a division of the European fuel manufacturing industry) develops scientific research and technical studies on the fuel industry’s products and operations, and their impact. Concawe is … [Read more...]
The final hurdle for 100% Sustainable Aviation Fuel? Turning Lignin biomass into the “aromatic” component
Making 100% sustainable aviation fuel seems a long way away. Aircraft need energy-dense power, as delivered by fossil fuels, and sustainable alternatives are being developed. But a big challenge is that 10% - 25% of the fuel must be “aromatic” which neither thickens nor freezes at cold altitudes. Also, aromatics get absorbed by the plastic seals, make them swell, and ensure those seals between various components in the aircraft’s fuel system are … [Read more...]
Nuclear power capacity is growing globally. Where, how and why
Ewan Thomson at the World Economic Forum summarises the state of nuclear power worldwide. In 2020 it made up 10% of global electricity generation, more than all the wind and solar PV combined. It’s the second-largest source of low-emissions electricity. But many advanced countries are no longer backing nuclear, citing safety and cost concerns, and instead are pushing the growing number of alternative clean energy technologies. Nevertheless, … [Read more...]
Poorly defined “efficiency” incentives birthed the SUV. Beware the same mistake with “clean energy” jobs, “domestic” batteries + more
Financial support for the transition needs clear and carefully chosen definitions of what qualifies for that support. Getting it wrong leads to unintended consequences, some which may not reduce emissions, explains James Sallee at the Energy Institute at Haas. Ever wondered why SUVs and big cars proliferated after the 1970s in the U.S. (and are on roads all over the world now)? The 1970s oil crisis triggered new rules that penalised fuel … [Read more...]
4 CEOs explain their innovations: EV charging, aviation fuel, hydrogen fuel cells, nuclear waste-to-energy
To meet our global climate targets, new solutions, technologies and pathways will be needed. Existing technologies, on their own, can’t be scaled up fast enough to do it. Robin Pomeroy and Kate Whiting at the World Economic Forum pick out highlights from their podcast that hears from four CEOs of innovative companies, covering EV charging, aviation, hydrogen fuel cells, and new nuclear. Today’s millions of EV charging points needs to rise to 450m … [Read more...]
SAFFiRE: cheap, Sustainable Aviation Fuel from agricultural waste
SAFFiRE (Sustainable Aviation Fuel From [i] Renewable Ethanol) is a 10-ton-per-day pilot plant project. The goal is 7bn gallons of sustainable, low-carbon aviation fuel by 2040. Ryan Horns at NREL explains that the sustainable fuel is made from corn stover, an agricultural waste product, chemically broken down into sugars that can then be converted to fuels. The SAFFiRE process can take advantage of the existing infrastructure of over 200 ethanol … [Read more...]
A carbon tax on car fuel? A fossil car phase-out date is more effective
The EC is working on a carbon tax on car drivers as part of its big climate plan review in June. William Todts at T&E warns that the EC shouldn’t make the same mistake French President Macron made back in 2018 when severe gilets jaunes protests against a fuel price hike made him back down. A very high carbon price, decided by the market, may have the same effect, getting us nowhere. Instead, Todts gives his three point plan. The carbon tax … [Read more...]
Why Autogas Could Help Us All Breathe More Easily
Since the COVID-19 crisis and subsequent lockdowns, many cities around the world experienced a marked improvement in urban air quality, but with traffic getting back to “normal”, air pollution is rebounding and, alongside the continued public health crisis, we are now facing an economic recession. Mobility is essential to securing jobs and getting the economy back on track, but it should not come at the expense of the environment. Filipa Rio, … [Read more...]
17 GtCO2 avoided, $5tn saved: Rising U.S. car fuel efficiency since 1975
Since the 1970s, fuel-economy improvements in U.S. “light-duty” vehicles, with a contribution from rising gasoline prices, have saved 17bn tonnes of CO2, according to a new study reviewed by Josh Gabbatiss at Carbon Brief. That makes rising fuel efficiency’s impact on emissions reductions second only to that of coal-to-gas. New cars, vans and light trucks get about twice as many miles to the gallon as 1975 models. The amount of gasoline therefore … [Read more...]
Decarbonisation of Transport: Options and Challenges – free Brussels debate and report launch
Decarbonisation of transport remains one of the most challenging aspects of the transition to a sustainable energy system. Focussing on road transport, the European Academies' Science Advisory Council (EASAC)'s upcoming report contains detailed recommendations for actions on the part of all major stakeholders. The report will be officially launched at what promises to be a fascinating event featuring a high-level panel discussion with speakers … [Read more...]
