What if CO2 could be captured and, rather than locked away underground for eternity, turned into a stable powder that can be used in fuel cells to produce electricity? David Chandler at MIT describes research there and at Harvard that has demonstrated a new process that has a 96% conversion rate. It’s been tried before, but the conversion rates were an unusable 20%. The CO2 is converted into formate and used like hydrogen or methanol (both strong … [Read more...]
How to manage price risk as the EU shifts from Russian Gas to Renewables
Europe is phasing out Russian gas and replacing it with more renewables. That means there will be greater demand variability and a resulting impact on European spot gas prices. The problem is that long-term contracting, the traditional way for buyers to mitigate spot price risk, is incompatible with Europe’s climate objectives of reducing long term consumption of gas. Kong Chyong at the Center on Global Energy Policy proposes alternative policy … [Read more...]
Italy: 71 GWh of additional Grid Storage required by 2030 says Terna
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 Friday at 11:00 CET, Energy Post is exclusive media partner to a dedicated webinar (organised by ATA Insights/RENMAD) on the topic REGISTER FREE HERE. In this article, Sara Stefanini summarises the Terna study, along with others, … [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...]
1,500GW of Renewables deployment delayed globally because Grids aren’t modernising fast enough
A first-of-its-kind global country-by-country study, “Electricity Grids and Secure Energy Transitions” by the IEA finds that electricity grids are not keeping pace with the rapid growth of clean energy technologies. Without greater policy attention and investment, shortfalls in the reach and quality of grid infrastructure puts at risk our climate goals. Worldwide, we need to add or replace 80m kms of power lines by 2040 – an amount equal to the … [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...]
Concrete supercapacitor: works like a battery, much cheaper, easy to make
Capacitors work like batteries. They store and discharge electricity. David Chandler at MIT explains how researchers there have designed a supercapacitor from concrete and carbon black, two cheap and common materials. The beauty of the idea is that they can be incorporated into building foundations, thus installing a battery virtually for free. A concrete capacitor cube 3.5m wide can store 10kwh, enough for a household. Similarly, concrete … [Read more...]
Germany plans for Carbon Capture in Industry: emissions, potentials, costs
In the first article of this series, Simon Göss and Hendrik Schuldt at carboneer gave the background to Germany’s new drive for carbon capture, and summarised the industrial sectors that will be its focus. Here, the authors analyse the emission profiles of German industries (in particular: steel, cement, lime, chemicals, waste incineration) and the associated CCS potentials and costs. The first thing to note is that it’s the process emissions … [Read more...]
Rooftop Solar: will subsidies benefit wealthy early adopters, while grid limits lock out the latecomers?
Subsidies encouraging homeowners to install rooftop solar are being won by the affluent who can afford to be first movers. And when the technology has come down in price, the remaining majority of households will be shut out of the benefits of own-generation because the grid won’t have the capacity to integrate everyone. That’s the argument made by Juan Jose Cuenca Silva, Barry Hayes and Hannah Daly at the University College Cork who summarise … [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...]
Can we expect Gas price volatility and spikes this winter? Why?
Europe has done well in pivoting away from Russian gas imports. After painful energy prices rises in 2022 they have fallen steadily this year. LNG imports and the infrastructure to support them is growing. And Europe’s gas storage levels hit 90% capacity three months ahead of the November target. But the challenge is far from over, explains Michael Bradshaw at Warwick Business School. European gas prices remain 50% above their pre-invasion … [Read more...]
Does Nuclear slow down the scale-up of Wind and Solar? France and Germany can’t agree
France and Germany lead the camps in disagreeing on the future of nuclear in Europe. Camille Lafrance and Benjamin Wehrmann at CLEW take a deep dive into the reasons why, quoting experts and politicians. Germany’s vision of a fully renewables-based EU is at odds with France’s unwavering support for low-carbon nuclear energy. European-wide agreement on targets matter because they drive future investment in the targeted technologies and the design … [Read more...]
