The EU Emissions Trading System (EU ETS) is at a critical juncture as it navigates a path towards achieving a net-zero Europe by 2050. Amidst this transformation, the proposal to create the European Central Carbon Bank (ECCB) has sparked a range of criticisms. Some critics have raised valid concerns about the feasibility, necessity, governance, and potential drawbacks of such an institution. Robert Jeszke and Sebastian Lizak at the Centre for … [Read more...]
New Solar study: 50% of global power by 2050, even without more ambitious climate policies
Nadia Ameli at UCL and Femke Nijsse and Jean-Francois Mercure at the University of Exeter present their study that shows solar is on track to make up more than half of global electricity generation by 2050, even without more ambitious climate policies. This far exceeds any previous estimates: last year’s IEA World Energy Outlook predicted that solar would account for only 25% by 2050. The authors’ macroeconomic model takes the latest … [Read more...]
Thermal Energy Storage for heating and cooling Buildings: finding materials that melt at room temperature
Thermal Energy Storage (TES) in individual buildings can cut heating and cooling costs while delivering grid stability, explains Ryan Horns writing for NREL. Back in the 1800s blocks of ice were shipped to cities to cool buildings down. Today, research is underway to identify materials that can be heated or cooled by excess grid power and release or absorb heat when needed. Similarly, materials are being researched and developed that “phase … [Read more...]
Cost vs Resilience: Europe’s sourcing strategy will shape the regional Hydrogen economy
The upcoming EU Hydrogen Bank pilot auction and trilogue discussions are focussing minds on the future of hydrogen. Jonas Lotze and Massimo Moser at TransnetBW and Janina Erb, Roman Flatau, Felix Greven and Max Labmayr at d-fine present the results of their modelling of two hydrogen sourcing scenarios: "Global Market" (GM) where the import of hydrogen into Europe is unrestricted, and "Energy Resilient Europe" (ERE) where almost all hydrogen is … [Read more...]
IMF adds climate change to its economic risk assessments, pilots new lending tools
The International Monetary Fund (IMF) says its primary role is to help countries tackle balance of payments problems, stabilise their economies, and restore sustainable economic growth. Dileimy Orozco and Njavwa Sanga at E3G and Alexia Meynier at ENGIE Impact explain that the IMF has now elevated climate change to one of its top priorities, considering it a systemic risk for the stability of the global economy and financial system. Until now, the … [Read more...]
EU now has 9,000+ “energy communities”: smart, decentralised, flexible generation and consumption
The goal of the EU’s “Clean Energy for all Europeans package” (CEP), adopted in 2019, is to improve the functioning and design of Europe’s energy markets and systems. Luca Arfini, writing for ESCI, explains how, as part of the CEP, new market actors called “active customers/consumers and citizens” and “energy communities” are being established. As variable renewable generation grows, the whole system needs to be more decentralised, smarter and … [Read more...]
China’s Belt and Road Initiative is now building more Renewables, less Coal
Energy has always made up the majority of investments and construction deals signed through China’s Belt and Road Initiative (BRI). Until very recently these investments were dominated by fossil fuel projects. But in the first half of this year, over 40% of BRI energy projects announced were wind and solar, with 22% each for gas and oil, and zero for coal projects. The reasons include China’s stated commitment to clean energy, avoiding the risk … [Read more...]
Will AI queries increase Data Centre energy use by an order of magnitude?
Data centres globally consumed 220-330 TWh in 2021 (California uses around 278 TWh/year). How much more will they consume if AI takes off, given AI queries consume an order of magnitude more energy, and there are over 5bn internet users worldwide? The first step is to make a decent evidence-based prediction, but the U.S. and the EU are only expected to enforce reporting requirements next year, explains Meredith Fowlie at UC Berkeley’s Energy … [Read more...]
Using Generative AI to speed up and improve the Wind Turbine blade design process
Justin Daugherty at NREL describes research there on using generative AI to accelerate and improve the wind turbine blade design process. To keep up with the pace of change in the market (not just customer demands, but policy regulations and technological innovations), the current method uses simplified low-fidelity modelling because it’s quicker to turn around. But it is also less accurate. Researchers are exploring deep-learning models using … [Read more...]
Europe’s big Hydrogen ambitions won’t deliver. Stick to ammonia-fertiliser, refining, shipping, aviation (maybe later)
Europe’s hydrogen ambitions need a reality check. The EU’s goal to produce and import 20m tonnes of clean hydrogen by 2030 is now widely seen as completely unrealistic, says William Todts at T&E. The business case is not good enough because of the high costs that aren’t coming down as hoped. It’s why only 4% of hydrogen projects get financed. Far better to focus on no regrets, low infrastructure hydrogen applications for ammonia-fertiliser, … [Read more...]
Nations are on track to meet their NDC targets. The catch is those targets aren’t high enough for net zero by 2050
Globally, current Nationally Determined Contributions (NDCs) targets are within reach thanks to the increasing speed of clean energy transitions around the world. That’s as NDCs have, as planned, got more ambitious as nations have updated them every five years. The problem is current NDCs are still not ambitious enough to meet our actual 2050 net zero target. Daniel Wetzel, Gabriel Saive, Luca Lo Re and Alice Latella at the IEA summarise the … [Read more...]
China can learn from the EU about power market design and infrastructure build-out
How will China integrate its growing Variable Renewable Energy generation and create a nationwide energy system that avoids the risks of curtailment, stranded assets and blackouts? A good place to start is to learn from Europe. Helen Farrell at ECECP summarises their report that uses the European experience to model scenarios for China. China’s key challenges is that its power market lacks an effective auxiliary service market, a capacity market, … [Read more...]
How much protection from carbon-intensive imports will CBAM give to EU industries?
The EU’s Carbon Border Adjustment Mechanism (CBAM) is not a business-as-usual instrument that allows sectors to delay decarbonisation. It applies a levy on imported goods equal to the internal EU ETS-related carbon price, so that both EU-produced goods and those imported into the EU face similar carbon cost pressures. But sectors must use the CBAM phase-in period to decarbonise. Pablo Ruiz and Barbara Kölbl at Rabobank look at how different … [Read more...]
Simple superconducting diode can dramatically cut energy use in transistors, data centres
Some estimates say data centres could be consuming up to 20% of all power globally in ten years. That’s largely because the billions of transistors have to be cooled. Elizabeth Thomson at MIT describes breakthrough research that has made a superconducting diode that’s twice as efficient as the standard, therefore generating and wasting far less heat. What’s surprising is that some straightforward physics of materials was utilised, in contrast to … [Read more...]
Annual Energy Efficiency improvements must double to meet climate targets. We know how to do it
Global energy intensity – a measure of how efficiently the global economy uses energy – improved by just over 2% in 2022. That needs to double to 4% annually to 2030 to meet global efficiency targets, explains Brian Motherway at the IEA. If achieved, by 2030 one unit of energy used will generate 40% more economic output than today. That’s huge, and shows why few other policy areas offer such widespread benefits. More than half of the 150 … [Read more...]
