Direct capture of CO2 from the air is already established in pilot phase in sites around the world, but costs are very high. So it is puzzling that capturing CO2 direct from the sea is yet to be tested properly. After all, the concentration of CO2 in seawater is more than 100 times greater than in the air, pointing at a process that should be much more efficient. David Chandler at MIT looks at research there that has uncovered cheaper and more … [Read more...]
New AI model predicts 1.5C temperature rise is likely in 2030s even if emissions decline
A new artificial intelligence model is predicting that 2C warming is likely to occur and sooner than expected, even if current low-emissions strategies are successful, explains Josie Garthwaite at Stanford University. The Stanford-developed AI uses âneural networkâ learning from vast quantities of past data, predicting that the 1.5C threshold is likely to be crossed in the next 10 to 15 years. Thatâs regardless of how much greenhouse gas … [Read more...]
Virtual Power Plants: efficiently networked households wonât need new expensive generation
Virtual Power Plants (VPPs) are the next new innovation that can change the landscape of the global energy transition in our favour, cheaply and fast, explain Liza Martin and Kevin Brehm at RMI. Essentially, they link and aggregate hundreds of thousands of households and businesses to manage their electrical devices. Their thermostats, EVs, appliances, batteries, and rooftop solar arrays are coordinated to ensure loads, charging and discharging … [Read more...]
What if Exxon had acted on its 1970s climate forecast? No climate crisis, cheap energy, Exxon the unrivalled top global energy firm
In January the world media widely covered a paper published in Science that looked at the internal Exxon report that predicted the climate change crisis we now all know we are facing. The paper concludes that the Exxon forecasts were very accurate. John Grant at Sheffield Hallam University composes a counterfactual history of what would have happened in Exxon and the world had taken the report seriously and acted immediately. Yes, weâd have … [Read more...]
Steel decarbonisation: Australia must stop making excuses and follow Europeâs lead
Australian steel makers, major global exporters, must stop making excuses about decarbonisation and look to Europe for a role model, argues Simon Nicholas at IEEFA. A pattern of behaviour by Australiaâs steel makers reveals that their excuse is that low-carbon solutions are not yet ready, leaving only promises of carbon capture (as yet unproven at scale) some time in the future. Nicholas notes that these promises will never have to be kept by the … [Read more...]
Biofuel is approaching a feedstock crunch. How bad? And what must be done?
The IEA is warning that biodiesel, renewable diesel and biojet fuel producers are heading for a feedstock supply crunch over the next five years. Rising prices are the signal to seek out new supplies and solutions, which should â and are - driving the development of government programmes and industry innovation. Here, the IEA lays out their projections for 2022-2027, covering all the main feedstocks: sugars, maize, soy oil, rapeseed oil, palm … [Read more...]
How to sell Heat Pumps to the public in Europe
In EU households, 62.8% of energy consumption is for space heating, and another 15.1% for water heating, mostly powered by fossil fuels. Heating and cooling is responsible for 52% of final energy demand in Europe. So, with REPowerEU, the EU has once again strengthened support for heat pumps to achieve energy independence and climate goals. Heat pump sales in Europe grew by an unprecedented 34% in 2021, thanks to a total 2.18m heat pump units … [Read more...]
New U.S. âBuy Cleanâ plan earmarks billions for low-carbon cement, steel and other building materials
New guidance from the U.S. federal government, combined with historic Inflation Reduction Act investments, could turbocharge markets for low-carbon cement, steel, and other building materials. Victor Olgyay, Anish Tilak and Connor Usry at Rocky Mountain Institute explain how the new âBuy Cleanâ recommendations will mean the procurement of green building materials for federal building and transportation projects. That will lead to a boost in … [Read more...]
Fossil fuel producers can decarbonise by exporting Electricity, Hydrogen, and Steel
The compelling reason why fossil fuel producers will be needed even beyond 2050 is that they currently provide over 80% of global energy, and 90% of the worldâs population still needs the wealth creation that energy delivers, says Schalk Cloete. Given that, he summarises his co-authored paper that takes a close look at how a fossil exporter, Norway, can trade with an importer, Germany, while decarbonising. The modelling focusses on electricity … [Read more...]
Electricity market re-design should focus on the root cause of the crisis, Europeâs dependence on fossil fuels
Amidst the perfect storm of the pandemic, war in Ukraine, and extreme weather events, Bruce Douglas at Eurelectric urges us all not to lose focus on our decarbonisation targets. Energy savings, electrification and renewables are more important than ever to help reduce dependence on fossil fuels. Douglas explains that Europeâs electricity sector remains totally committed to the drive towards clean energy, citing examples. He summarises the … [Read more...]
âOptions to Reform the EU ETSâ: coping with price volatility and speculation (event summary)
Sara Stefanini provides a written summary of our panel discussion held on 31st March 2022, âOptions to Reform the EU ETSâ. Itâs a full summary of the 90 minute discussion (with a link to the video), but it begins conveniently with a summary of the highlights, leading with the role of financial players, who they are, the causes of price volatility, what reforms can create stability, and the cost of decarbonisation. The main concern is speculation … [Read more...]
Aviation, Steel, Shipping CEOs ask COP26 to back their decarbonisation pathways
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...]
China: decoupling GDP growth from rising emissions
To set up this weekâs important online event (Tuesday 13th & Wednesday 14th April) âChina: Carbon Neutral by 2060 -EFFICIENCY FIRSTâ we have an overview of Chinaâs energy transition. Everyone agrees its performance is critical for the world to achieve the global goal of limiting warming to 1.5C by 2050. China made significant progress in 2020 with policy frameworks, renewable capacity additions and EVs, but it also added 38 GW of new … [Read more...]
An EU ETS that lifts carbon prices too high can make clean energy transitions harder
This coming Friday 19th March, 11.00 to 12.30 CET, we have an online panel discussion plus audience Q&A on "The Role of the EU ETS in Decarbonisation to 2030". All are invited. We will dig into how the EU ETS is being shaped to ensure it meets its primary objective, the decarbonisation of Europe. To help set it up, Wanda Buk, Vice-President for Regulatory Affairs at PGE Group answers questions that are being asked of Polandâs position and its … [Read more...]
Climate Neutral Cities can be the key to winning public support for the European Green Deal
The EC is currently considering a mission proposal to achieve â100 climate neutral cities by 2030 â by and for the citizensâ. Arguing for its endorsement and the proposed umbrella governance, Simon Skillings and Eleonora Moro at E3G explain why cities are an ideal laboratory for tackling the big unanswered question: which European Green Deal (EGD) pathways will win genuine public support. No one should doubt that the EGD will be disruptive. So … [Read more...]
