In most lithium-ion batteries, the cathode contains cobalt. But cobalt is a scarce metal, found mostly in politically unstable countries, its extraction is hazardous for miners and generates toxic waste. And as demand for batteries globally keeps rising, so too will the cost of cobalt. Anne Trafton at MIT describes the development of an alternative cathode made of organic materials. Its structure is similar to graphite. It can conduct electricity … [Read more...]
Research into how electrons and protons couple at an electrode can create more efficient fuel cells, electrolysers
Every efficiency gain discovered in the lab feeds through to the final cost of electricity. Anne Trafton at MIT describes new research looking at how electrons and protons couple at an electrode surface, which drives electric current. It’s a critical step in many energy technologies, including fuel cells, hydrogen electrolysers, batteries, and CO2 conversion into chemical fuels. The first step was to develop a way to design electrode surfaces … [Read more...]
Batteries are still getting exponentially cheaper, more efficient: ready to displace half of global fossil fuel demand by 2045?
A new report by RMI says batteries are on the path to replace 175 EJ of fossil fuel demand in the power sector, 86 EJ of fossil fuels from road transport and can put at risk another 23 EJ from shipping and aviation. That equates to a phaseout of half of global fossil fuel demand in the next two decades. Daan Walter, Sam Butler-Sloss and Kingsmill Bond at RMI summarise the findings in six graphs with explanations. Battery sales are growing … [Read more...]
Italy: Capacity Auctions for 71 GWh of additional Grid Storage
Italy needs 71 GWh of new utility-scale electricity storage capacity by 2030 to meet EU targets to cut emissions by at least 55% by 2030, according to Terna which manages Italy’s transmission grid. ***STOP PRESS*** This Tuesday at 11:00 CET, Energy Post is exclusive media partner to a dedicated webinar (organised by ATA Insights/RENMAD) on Capacity Market Auctions REGISTER FREE HERE. In this article, Sara Stefanini summarises the Terna study, … [Read more...]
France is subsidising made-in-EU EVs with low carbon footprints. Europe must follow
Last year, France announced new green eligibility rules for awarding subsidies to EVs. Starting this year, an incentive of €5,000-€7,000 will only be awarded to electric cars with a production carbon footprint below 14.75 tonnes of CO2. It’s a first in environmental policymaking which the EU should be delivering across the region, says Lucien Mathieu at T&E. And not just for environmental reasons. It will promote EVs made in Europe where … [Read more...]
Global inflation: high borrowing costs threaten the continued growth in Renewables. What must be done?
Over the last decade, investors and governments got used to two supportive trends: relatively cheap capital from low interest rates, and steadily falling costs. However, this changed as the world emerged from the Covid pandemic and into the global energy crisis. In a new era of high interest rates, the impressive growth in renewables deployment is under threat, explain Tim Gould, David Fischer, Paolo Frankl and Heymi Bahar at the IEA. Renewables … [Read more...]
Four net-zero opportunities for 2024: wind, solar, lab-grown meat, positive tipping points
Will de Freitas at The Conversation draws attention to four reasons to celebrate 2023 and their implications for our drive to tackle climate change. Most will be familiar with the continued progress made with wind and solar, though they deserve repeating given its immense significance. Wind turbines now stand more than a quarter of a kilometre high, and will get taller. At that size, one turn of the blade will power an average home in the … [Read more...]
The E-bike revolution is already underway (in developing countries): 280m micro-vehicles on the road and rising
While we’re all still waiting for the tipping point for EVs, it might have already happened for e-bikes – just not in rich countries. Car-owning nations will always struggle to switch to micro-mobility. But in China and other developing nations, owning a moped or bicycle is very common, so the switch is much easier, explain Muhammad Rizwan Azhar and Waqas Uzair at Edith Cowan University. It’s why, globally by 2022, there were over 280m electric … [Read more...]
China is still playing the long game with its ‘new three’: solar cells, lithium batteries, EVs
China’s “new three” – or xin san yang – are solar cells, lithium-ion batteries, and EVs. The term harks back to the concept of its “old three” that were once the pillars of its exports: clothing, home appliances and furniture. China’s success is seen in the numbers: it accounts globally for 80%+ of solar cell exports, 50%+ of lithium-ion batteries and 20%+ of EVs. You Xiaoying, writing for China Dialogue, interviews experts and quotes reports … [Read more...]
Modelling revenue potential for Germany’s Battery Storage future
In the last ten years Germany has installed battery storage systems totalling 6.5 GW of power and 10.1 GWh of energy. Storage is an essential part of every nation’s electrification plans: for peak shaving, uninterruptible power for industrial customers, use as a buffer, and self-supply in households. Elena Dahlem and Alex Schmitt at Energy Brainpool start with a summary of storage’s use in the household, industrial and large-scale sectors. They … [Read more...]
Clean energy is driving job growth, but skills shortages are a major barrier
The second edition of the IEA’s annual World Energy Employment report measures energy sector employment by region, fuel, technology, and value chain. Globally, energy employment rose to 67m people in 2022. Over half of employment growth since before the pandemic was in just five sectors: solar, wind, EVs, batteries, heat pumps, and critical minerals mining. In fact, clean energy jobs overtook fossil fuels in 2021. But skilled labour shortages are … [Read more...]
EU legislators must avoid crippling clean tech with a blanket ban on PFAS (per-and polyfluoroalkyl substances)
A blanket ban on all types of PFAS (per-and polyfluoroalkyl substances), or ‘forever chemicals’, is currently being considered by the European Chemicals Agency (ECHA). PFAS are used in cleaning products, non-stick pans, personal care products and more, so a ban on these will save lives and deliver sustainable practices. But, as Daniel Fraile at Hydrogen Europe explains, the PFAS subgroups of fluoropolymers and perfluoropolyethers are used in … [Read more...]
Make EV batteries bidirectional, get GWs of storage for the Grid
How to cope with the hourly, daily and seasonal variation in demand as regions electrify more, depend more on variable renewables like wind and solar, and cut baseload fossil generation? Storage shifts load nicely. But why build grid-scale batteries when millions of little batteries in our EVs are sitting idle in our driveways for most of the time? As Mark Specht at the Union of Concerned Scientists explains, it’s why in California a bill is … [Read more...]
IRENA’s Innovation Week 2023: Renewable solutions to decarbonise end-use sectors
At the end of September IRENA held a four-day event “Innovation Week 2023: Renewable solutions to decarbonise end-use sectors” in Bonn, Germany. A wide range of speakers discussed tangible solutions to decarbonise energy intensive sectors such as transportation, buildings and industry, informed by first-hand project experiences and supported by insights from IRENA’s in-depth analyses. Topics included direct and indirect electrification, green … [Read more...]
Scaling up global grid-scale Storage to 80GW/year (it was 16GW in 2022)
Globally, annual additions of grid-scale battery storage must rise to 80GW between now and 2030, explain Amit Jain, Gabriela Elizondo Azuela and Aakarshan Vaid at the World Bank, writing for WEF. In 2022 it was only 16GW. The biggest gap, perhaps understandably, is in developing countries. It’s in these regions where renewables auctions for deployment – primarily solar and wind – need to start including hybrid storage as part of the package. The … [Read more...]
