What can the Industrial Revolution and the more recent Information Revolution teach us about the Energy Revolution we are going through now, ask Yuki Numata, Laurens Speelman and Marissa Gantman at RMI. Importantly, the same questions that were ignored or dismissed in those past transitions will help us shape our energy transition to make it better, faster, less wasteful and polluting, as well as more equitable. The authors reveal a 4-part … [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...]
The final hurdle for 100% Sustainable Aviation Fuel? Turning Lignin biomass into the “aromatic” component
Making 100% sustainable aviation fuel seems a long way away. Aircraft need energy-dense power, as delivered by fossil fuels, and sustainable alternatives are being developed. But a big challenge is that 10% - 25% of the fuel must be “aromatic” which neither thickens nor freezes at cold altitudes. Also, aromatics get absorbed by the plastic seals, make them swell, and ensure those seals between various components in the aircraft’s fuel system are … [Read more...]
Spain: as Renewables rise, managing supply and demand is the next challenge
In May this year Spain reached a landmark day when it was powered 100% by renewables - solar, wind and hydroelectric power - from ten o'clock in the morning until seven o'clock in the evening. In four years the share of renewable energy generation rose from 37% to 50%, while non-renewables dropped from 62% to 49%. Its draft Law on Climate Change and Energy Transition targets 35% of renewable energy in final consumption by 2030 and 100% in the … [Read more...]
Sodium-ion batteries ready for commercialisation: for grids, homes, even compact EVs
Sodium-ion (Na-ion) batteries, a much more abundant and cheaper alternative to the standard Lithium-ion, are on the verge of commercialisation, explain Carlos Ruiz, Martina Lyons, Isaac Elizondo Garcia and Zhaoyu Wu at IRENA. Though there’s enough Lithium in the world to support global electrification targets, tightening demand and supply chain constraints point at the urgent need for an alternative. The cost of a Na-ion battery cell is expected … [Read more...]
Iron and Steel: how can Hydrogen and Direct Electrification replace fossil-based production?
Karan Kochhar, Luis Janeiro and Francisco Boshell at IRENA look at the decarbonisation of iron and steel. They account for about 7% of global energy–related carbon emissions. The authors explain what’s needed for green hydrogen and direct green electrification to take over from traditional fossil-based production. Many projects are in the pipeline, and the authors reference case studies like H2 Green Steel, SIDERWIN and Boston Metal. Though that … [Read more...]
Farming Algae for Carbon Capture: new research cuts “fouling.” Scale-up in 3 years?
Natural marine algae already account for 50% of global CO2 removal. Farming it at scale in artificial tanks or tubes would take up a fraction of the land footprint of terrestrial plants. And algae can grow up to 50 times more quickly than land-based plants. It could be a game-changer that brings carbon capture costs down and make it a commercial reality. Here, David Chandler at MIT explains how new research there can make farming algae much more … [Read more...]
Ammonia from water microdroplets: lab demonstrates cheap, low-tech production
Very early stage research has discovered a new way of making ammonia cheaply, on a small scale (or large, if you want!), and with no harmful emissions, explains Adam Hadhazy writing for Stanford University. The process uses a cocktail of water, nitrogen gas, and a solid catalyst sprayed through a simple, low-tech instrument to make the ammonia. In contrast, the existing industry-standard Haber-Bosch process is energy intensive, large scale, and … [Read more...]
Perovskite: abundant, cheap, printable solar cells demonstrated, ready to generate power
Laboratories around the world are racing to make printable perovskite solar cells, produced in abundance and so thin they can be wrapped around almost anything. It’s a huge advantage over the typical silicon cell that is relatively big and fragile. And perovskite is much less expensive to produce. David Beynon at Swansea University describes research there that has demonstrated how a roll of plastic film can be loaded into a printing press to … [Read more...]
Europe: preventing a “carbon wall” between the West and the ten Central and Eastern EU nations
Diana-Paula Gherasim at the IFRI Centre for Energy & Climate summarises her 36-page data-rich report on the progress and challenges for the ten Central and Eastern EU (CEECs) countries in decarbonisation. The Russian invasion of Ukraine has focussed all minds on energy security and the best solutions: less fossils, efficiency gains and clean energy made in the EU. Gherasim says that vitally important progress is being made in avoiding a … [Read more...]
4 CEOs explain their innovations: EV charging, aviation fuel, hydrogen fuel cells, nuclear waste-to-energy
To meet our global climate targets, new solutions, technologies and pathways will be needed. Existing technologies, on their own, can’t be scaled up fast enough to do it. Robin Pomeroy and Kate Whiting at the World Economic Forum pick out highlights from their podcast that hears from four CEOs of innovative companies, covering EV charging, aviation, hydrogen fuel cells, and new nuclear. Today’s millions of EV charging points needs to rise to 450m … [Read more...]
Geothermal’s full potential: 24/7 power everywhere, storage, environmental mineral extraction
Geothermal is not just for generating energy. It can be used for storage and extracting minerals too. Kelly MacGregor at NREL summarises the research into taking geothermal to the next level and making it a solution to multiple challenges. Depending on how far down you dig, geothermal is available for running utility-scale power plants as well as heating and cooling individual districts, buildings and houses. And new techniques are being … [Read more...]
Silicon Valley Bank failed. Don’t blame the Climate Tech it backed
Silicon Valley Bank in the U.S. was a favourite for climate tech start-ups. So its recent collapse inevitably raised questions over whether those start-ups and by extension the whole climate innovation ecosystem was much more fragile than previously thought. Rushad Nanavatty, Colm Quinn and Amy Yanow Fairbanks at RMI explain why that’s not the case. Instead, it was an old-fashioned bank run caused by poor risk management, weakened regulation of … [Read more...]
“Combustion” can make cathodes for lithium-ion batteries more cheaply, quicker, using less energy
Burning things produce soot. And that soot contains materials that have been morphed into something else. As Nancy Stauffer at MIT explains, new research there has shown the burning process can be used to produce cathodes far more cheaply, quicker, more simply, and with less energy than the standard method. It’s another example, from an unexpected direction, of innovations cutting the costs of an essential component of the energy transition: … [Read more...]
Direct capture of CO2 from seawater: new research cuts costs, ready for pilot in 2025
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...]
