The seven âhardest to abateâ industries together account for 30% of global greenhouse gas emissions. They are aviation, steel, shipping, cement, aluminium, trucking and chemicals. John Matson at RMI explains how a growing number of sector-leading corporates in aviation, steel and shipping are now openly backing net-zero pathways. He quotes CEOs and top executives (ArcelorMittal, United Airlines, Trafigura) on what they say they are determined to … [Read more...]
New cooling system for inverters brings electric Heavy-Duty Trucks closer
39% of greenhouse gas emissions in the transport sector comes from heavy-duty trucks. Commercial batteries struggle to deliver enough power to make electrification feasible for heavy-duty applications. Rebecca Martineau at NREL explains how a working prototype, developed with the heavy machinery manufacturer John Deere, is now getting a 378% increase in power density. The key to the innovations rests on a state-of-the-art thermal management … [Read more...]
Giving car manufacturers e-fuel credits will slow the rise of EVs
Transport & Environment (T&E) explains why e-fuel credits should not be included in the EUâs CO2 standards for new cars. If they are, it would give carmakers the option to claim an ICE vehicle as low- or zero-emission. But carmakers have no control over what fuel their customers put in their cars, making the regulation impossible to monitor. That opens the door to double-counting emission reductions with other existing regulations (Fuel … [Read more...]
Renewable Hydrogen: what policy instruments are needed to reach the new targets?
A comprehensive mix of policy instruments is needed to ensure that the EU meets its ambitious hydrogen targets. What should they look like? Pia Kerres, Matthias Schimmel and Corinna Klessmann at Guidehouse quote their study, done in collaboration with Agora Energiewende, for the answers. Industry and long-haul transport should be the main customers for hydrogen. The big challenge is to cut the cost of hydrogen production; itâs too expensive and … [Read more...]
EU âFit for 55â: how it impacts the EU ETS to accelerate emissions reductions
Christoph Kellermann, Lun Zhou and Simon Göss at Energy Brainpool explain how the EUâs new âFit for 55â proposals, released in July, will impact the EU Emissions Trading Scheme (EU ETS), hailed as one of the most effective ways of reducing emissions. The authors cover the changes to the existing ETS, the planned new ETS for road transport and buildings, the controversial Carbon Border Adjustment Mechanism (CBAM), and the new CO2 standards for … [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...]
What if Carbon Capture fails? Modelling the consequences and solutions
Most policy scenarios being used by governments include carbon capture as a vital tool to reduce emissions. Though itâs far from proven at scale, models assume that between 2030 and 2050 carbon dioxide removal (CDR) will get its act together and deliver on its part in the net-zero puzzle. Assuming that will happen, burning fossil fuels can continue for longer. But Neil Grant and Ajay Gambhir at Imperial College London, writing for Carbon Brief, … [Read more...]
The EUâs âFit for 55â package: a primer on the EU ETS and other main policy levers
On July 14 the European Commission will present the much awaited âFit for 55â legislative package. Lara Dombrowski and Simon Göss at Energy Brainpool have written a very useful primer on whatâs at stake for the EU ETS, along with a summary of the other main policy levers that will be decided upon. The authors describe the EU ETS as the central instrument for reducing greenhouse gas emissions. It caps emissions for 10,000 power sector, industrial … [Read more...]
Where to start building Hydrogen pipelines? Near industrial hubs for steel, ammonia, and plastics
Converting gas pipelines to carry hydrogen is going to be expensive. We donât even know how much hydrogen weâll really need in 2050, given electrification â the cheaper and preferred option to replace fossil fuels â will always be the first option. But we do know that certain industries like steel, ammonia, and plastics will always need hydrogen as a feedstock. Writing for WEF, Kevin Tu, Matthias Deutsch and Gniewomir Flis at Agora Energiewende … [Read more...]
Aviation should be given target dates for zero-emissions. Itâs working for cars and trucks
The French governmentâs decision to ban some short-haul flights if there is a rail alternative under two and a half hours is only symbolic, says Andrew Murphy at T&E. It would reduce French aviation emissions by only 0.8%. Expanded to rail journeys under five hours and itâs still only 4.5%. Long-haul flying is the much bigger problem, but the resulting emissions are outside of Franceâs current climate target. Instead of just talking about … [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...]
Which sectors need Hydrogen, which donât: Transport, Heating, Electricity, Storage, Industry?
Which sectors are most suited to hydrogen, and which are not? For the answer, six academics from the UK and the Netherlands - Tom Baxter, Ernst Worrell, Hu Li, Petra de Jongh, Stephen Carr, and Valeska Ting â use their areas of expertise to neatly summarise hydrogenâs pros and cons in Road and Rail, Aviation, Heating, Electricity and Energy Storage, and Heavy Industry. Their general message seems clear: hydrogen is still very expensive, so it can … [Read more...]
Franceâs recovery plan: will support for emissions-high sectors compromise a new Green economy?
The French recovery plan, formally presented today, combines emergency rescue measures, economic stimulus and longer-term investments. A substantial âŹ32bn out of the âŹ100bn budgeted is earmarked for the green economy. But SĂ©bastien Treyer at IDDRI asks whether rescue measures for traditionally emissions-high sectors - tourism, aviation, automotive, buildings, agri-food â will collide with climate targets. He references studies that should be used … [Read more...]
