Event summary: “Bioenergy after REDIII – sustainable, climate neutral fuels for industry, transport and negative emissions”

by

Sara Stefanini provides a written summary of our panel discussion held on Wednesday 4th October 2023. It’s a full summary of the 75 minute discussion, and begins conveniently with a summary of the highlights. Under the recently revised Renewable Energy Directive (REDIII) bioenergy can be counted towards the renewable energy targets – provided that it meets strict sustainability criteria. Bioenergy already accounts for 60% of the EU’s renewable … [Read more...]

Concawe Symposium tackles climate and pollution as RED commits fuel companies to 29% renewable content from 2030

by and

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...]

Turning Ethanol production’s CO2 by-product into E-Fuels using Wind power

by

With vast open spaces, Midwest states in the U.S. produce millions of gallons of ethanol from corn as well as thousands of kilowatt-hours of electricity from wind farms every year. Research led by NREL is working on using wind power to drive electrolysers that turn the ethanol’s CO2 by-product into e-fuels, explains Erik Ringle at NREL. A typical 50 million-gallon-per-year ethanol plant releases 14 tons of CO2, a natural by-product of … [Read more...]

EVs vs Biofuels: new study looks at ethanol’s impact on agricultural land use, food prices, emissions

by

For transport, biofuels have lower emissions than gasoline/petrol, but EVs will have the lowest emissions of all. Hence the opposition to those biofuels, along with objections to the valuable cropland used to make the ethanol. But the overall advantage depends on the speed of transition to EVs charged with clean electricity. Now, a calculation has been made of the amount of agricultural land preserved for global food production - or kept as … [Read more...]

SAFFiRE: cheap, Sustainable Aviation Fuel from agricultural waste

by

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...]

Engineered soil microbe can convert CO2 20 times faster than natural photosynthesis

by

New research led by the U.S. Department of Energy’s SLAC National Accelerator Laboratory and the Max Planck Institute for Terrestrial Microbiology in Germany has shown how a bacterial enzyme found in the soil can be made to convert carbon dioxide into carbon compounds 20 times faster than plant enzymes do during natural photosynthesis. As Glennda Chui at Stanford University explains, it’s very early days but could open a door to artificially … [Read more...]

Russia-Ukraine stalls EU Biofuels, but accelerates its medium/long-term targets

by

Rising food and fuel costs are pushing several EU countries to freeze or lower 2022-2023 low-carbon blending mandates for transportation fuels. That will likely mean a rise in emissions, but only in the short term, says Cornelius Claeys at Stratas Advisors. However, the same policymakers understand that ending imports of fossil fuels from a belligerent Russia is an opportunity to raise low-carbon targets for the medium and long term. So, right … [Read more...]

Record Renewables additions for 2021 and 2022 despite supply bottlenecks prove Solar & Wind’s resilience

by

Despite – or perhaps because of – global market and political turmoil, renewable power is set to break another record in 2022. That’s after 2021 also saw record new capacity from solar, wind and other renewables worldwide. It’s mainly driven by solar PV in China and Europe as governments around the world take advantage of renewables’ energy security and climate benefits, according to the IEA’s latest Renewable Energy Market Update. 295GW of new … [Read more...]

Event summary: “Unlocking the potential of Bioenergy”

by

Sara Stefanini provides a written summary of our panel discussion held on Thursday March 17th 2022. It’s a full summary of the 90 minute discussion (including audience questions), but it begins conveniently with a summary of the highlights (potential for bioenergy, hard-to-abate sectors, sustainability, policy needs). Those highlights include the need to scale bioenergy up from around 50 EJ today to 150 EJ by 2050; the importance of carbon … [Read more...]

Biomethane for decarbonising transport: the Swedish example

by

Biomethane has a critical role to play in the decarbonisation of transport, particularly long-distance trucks and ships, where electrification is more difficult and expensive. Angela Sainz Arnau at the European Biogas Association explains that biomethane represents one of the lowest greenhouse gas intensive pathways when the whole emissions lifecycle is measured. However, when nations implement bans on internal combustion engines to cut the use … [Read more...]

Green hydrogen-based fuels pivotal in decarbonising Shipping by 2050

by and

The international shipping sector’s emission levels are comparable to Germany’s. Like aviation and heavy transport, reaching net-zero will need renewable fuels – direct electrification won’t be sufficient. Existing fossil fuel engines allow for biofuel blends of up to 20% without any modifications, and 100% methanol engines are a proven technology. Making sufficient quantities of clean fuels - without consuming food crops – is the challenge. … [Read more...]

Engineering yeast to create Biofuels from non-food crops (straw, grass, cellulosic waste)

by

Using ethanol can reduce the global consumption of fossil fuels. But, commercially, ethanol in the U.S. is produced from corn and not enough is grown to make a significant impact on U.S. fuel needs. Anne Trafton at MIT describes research that has engineered yeast to break down straw and woody plant material to create ethanol as efficiently as it’s done from corn. High yields of ethanol were extracted from five different types of cellulosic … [Read more...]

Aviation and Shipping emissions: will Biden take on the challenge?

by

William Todts at Transport & Environment is very worried about the Biden administration’s approach to aviation and shipping emissions. The signals are that the U.S. wants to work through the International Civil Aviation Organization (ICAO) and the International Maritime Organization (IMO). But they have neither the ability nor the means to spur technological breakthroughs. That matters, because it’s only the use of alternative fuels that can … [Read more...]

Clean Trucks are coming: a review of battery, hydrogen, synthetic fuels and more

by

New EU fuel efficiency rules are forcing truck makers into a race to get their low emission vehicles onto the roads. From 2025, newly registered trucks must have 15% lower emissions, and from 2030 it’s 30%. Battery-electric drivetrains are most likely to dominate, assisted in their evolution by the assured progress and charging infrastructure of EVs. Hydrogen fuel cells and synthetic fuels are also in the game, though hindered by the inevitable … [Read more...]

A new EU Gas Market must expose it to all clean energy solutions, not just gas-on-gas

by and

Towards the end of this year the EC is expected to issue new proposals for gas legislation, a once in a decade market reform. Simon Skillings and Lisa Fischer at E3G highlight the big difference between the design of gas and electricity markets for Europe. The electricity market is growing, the gas market needs to shrink. The authors quote figures showing that the EU's 55% emissions reduction target for 2030 means natural gas use will reduce by … [Read more...]
