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
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...]
Russia-Ukraine stalls EU Biofuels, but accelerates its medium/long-term targets
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...]
Event summary: âUnlocking the potential of Bioenergyâ
Sara Stefanini provides a written summary of our panel discussion held on Thursday March 17th 2022. Itâs 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
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...]
Community Biomass: for energy independence, stable prices and local control
Energy independence is now at the top of the EUâs agenda. Almost all Europeâs biomass is already locally produced, contributing around 60% of the EUâs renewable energy. Marine Perrio at IEECP makes the case for promoting biomass prosumer projects. She points at regions dependent on biomass that have reported stable energy prices in the midst of the drastic increases in gas, oil and coal prices. Biomass uses organic feedstock from agriculture, … [Read more...]
Biomass for industrial heat
On Thursday 17th March at 12.30CET our latest Energy Post panel, âUnlocking the potential of bioenergyâ boasts representatives from two of the most challenging areas for decarbonisation: the cement and aviation industries. Taking part are  Winston Beck, Head of Government Affairs at HeidelbergCement and Laurent Donceel, Senior Policy Director at Airlines for Europe. They will be joined by Thomas Meth, Chief Commercial Officer at Enviva (event … [Read more...]
Activating a community energy market for bioenergy: a new e-market environment connects biomass heating supply chain stakeholders
The e-market environment supports various supply chain stakeholders when developing a community bioenergy project on defining the services and activities needed to support their cases. It demonstrates the various stakeholder interactions and activities/services that must take place to set up an effective and sustainable local supply chain and a community bioenergy project, streamlining the process. The user-friendly, easy to use and intuitive … [Read more...]
Engineering yeast to create Biofuels from non-food crops (straw, grass, cellulosic waste)
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 itâs done from corn. High yields of ethanol were extracted from five different types of cellulosic … [Read more...]
Sustainably harvested Forest Biomass can help replace coal and gas
Burning sustainably harvested wood pellets emits far less carbon than burning coal or gas. Thatâs the main reason why it should be used in the global energy transition, argues Jennifer Jenkins at Enviva. Coal is declining, but not fast enough. Gas consumption is rising. Forest biomass can more easily be swapped in than wind and solar to provide dispatchable power. But it must be done sustainably. Referencing her white paper, Jenkins sets out the … [Read more...]
Aviation and Shipping emissions: will Biden take on the challenge?
William Todts at Transport & Environment is very worried about the Biden administrationâs 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 itâs only the use of alternative fuels that can … [Read more...]
Bioenergy is the undervalued pillar of the clean energy transition
Bioenergy is already the worldâs largest source of renewable energy, responsible for 70% of the supply (and around 10% of total primary energy). Burning organic matter goes back to the invention of fire and is still commonplace around the globe. Yet it gets hardly any of the attention and policy support thatâs given to other clean energy technologies like solar, wind and now hydrogen. Bioenergy can and should play an even greater role, explain … [Read more...]
Biofuels vs Hydrogen: which can fuel aviation, shipping, trucks?
The positive signals coming from EV sales and charge points contrast with the lack of progress in finding alternative fuels for aviation, shipping and trucks. Cornelius Claeys runs through the prospects for biofuels and hydrogen to power long-haul transport. Biofuels are already used as a substitute for fossil fuels, and EV uptake will usefully free them for fuelling heavy transport. But as decarbonisation ambitions rise the pressure on scarce … [Read more...]
Optimising Cyanobacteria for carbon fixation and biofuels
The landscape can be changed for energy transition technologies by research breakthroughs, and that includes work on bacteria and proteins. The National Renewable Energy Laboratory (NREL) and its partners have been running experiments on cyanobacteria. These single-cell organisms, also using photosynthesis, fix carbon dioxide twice as efficiently as plants. They grow rapidly, doubling their numbers in three hours. The first step is to understand … [Read more...]
Biogas and Biomethaneâs untapped potential across the world
The IEAâs World Energy Outlooks have no doubt that electrification alone cannot meet our climate goals. Thatâs why natural gas continues to play a major role. But biogas and biomethane have the potential to replace 20% of that gas, says the IEAâs special report âOutlook for biogas and biomethane: Prospects for organic growthâ. At present only a fraction of that is being utilised. Here the IEA summarises their comprehensive report. Costs are the … [Read more...]
