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...]
EU states agree deal on electricity market to protect consumers from price volatility, boost cheap renewable power
On Tuesday EU member states finally agreed on how to reform the bloc's electricity market after long months of difficult negotiations. The introduction of long-term contracts, particularly contracts for difference (CfDs), should stabilise prices for consumers and give certainty to investors in new generation. But the big concern had been how the state support implicit in CfDs might be used to bias the playing field in favour of nuclear and coal, … [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...]
Belgium: commercially viable Rooftop Solar for social housing. No installation subsidies, lower bills
Rooftop solar is becoming a key component of the roll-out of clean energy. But whereas the decision to install is straightforward for homeowners, how do tenants in social housing blocks take advantage of the subsidies and lower electricity prices? Sven Van Elst at ASTER and Maarten Michielssens at Energy Vision, writing for WEF, describe their project that is installing rooftop solar, free, for 52,500 social rental homes in Flanders, Belgium. No … [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...]
U.S. Inflation Reduction Act: one year on, a summary of impressive progress in the energy transition
The U.S. Inflation Reduction Act has been described as unprecedented in its ambition for the nation’s energy transition. One year on from the passing of the bill in August 2022, Hannah Perkins and Adam Aston at RMI describe the progress on implementation as unprecedented too. The authors break their review down into categories: clean tech manufacturing, electrifying transport, greening buildings, decarbonising electricity, transforming industry, … [Read more...]
Electricity Market Design – creating the stimulus for competitive Offshore Wind within the internal energy market
Ahead of the upcoming discussion in Brussels (September 18, 15:00, Polish Embassy REGISTER HERE) on how to stimulate renewable investment, see below for a reminder of what was discussed at our conference before the summer. This time around, following an open address by Wanda Buk, VP Regulatory Affairs at PGE, PGE Baltica's CEO, Arkadiusz Seksciński will be joined by Thor-Sten Vertmann, Electricity Market Design (EMD) expert within Ms Kadri … [Read more...]
Rooftop Solar for industry: up to 35% of U.S. manufacturing sectors could supply all their own power
Rooftop solar could supply the complete electricity needs of 5-35% of U.S. manufacturing sectors, explains Matthew Eckelman at Northeastern University who summarises his co-authored paper “Technical feasibility of powering U.S. manufacturing with rooftop solar PV”. At present, only 0.1% of industrial electricity demand in the U.S. is supplied by on-site sources of renewable energy. But large, unobstructed industrial rooftops and the declining … [Read more...]
Europe’s grid bottlenecks are delaying its energy transition
***While you're here... REGISTER NOW for "REPowering the grid for Solar PV" with the Vice-President of Tauron, DG ENER C, Eurelectric and SolarPowerEurope - Online Wednesday September 20 from 11:00 to 12:15 CEST*** No amount of record sales and deployment in Europe of heat pumps, EVs, solar farms, wind turbines and all the rest will guarantee the region meeting its electrification targets if the grids aren’t ready to integrate them. As … [Read more...]
Only certain types of Hybridisation (Wind or Solar + Storage) beat building expensive transmission lines
In some regions, the roll out of new wind and solar has outpaced new transmission. That causes “congestion” at times when the variable renewables are producing too much power locally, and cannot sell the excess, which squeezes profitability. That’s certainly the case in the U.S. now. One answer is “hybridisation” where storage is built alongside the renewables, to save that excess power for when it can be sold later. Julie Mulvaney Kemp at … [Read more...]
Nuclear power capacity is growing globally. Where, how and why
Ewan Thomson at the World Economic Forum summarises the state of nuclear power worldwide. In 2020 it made up 10% of global electricity generation, more than all the wind and solar PV combined. It’s the second-largest source of low-emissions electricity. But many advanced countries are no longer backing nuclear, citing safety and cost concerns, and instead are pushing the growing number of alternative clean energy technologies. Nevertheless, … [Read more...]
Russia’s war has exposed France and Germany’s energy policy differences. Can it also bring them together?
France and Germany combined account for 45% of EU GDP and 40% of energy consumption. No wonder they are the most influential EU members. But the Russia-induced energy crisis has forced both Paris and Berlin to expose and admit the differences in their national energy strategies, and that has made a search for a unified voice for Europe’s ambitious climate targets much harder to achieve, explain Camille Lafrance and Benjamin Wehrmann at CLEW. … [Read more...]
Long-duration storage: mechanical, electrochemical, thermal. We’ll need all three
“Long-duration” means the amount of time a power system can discharge electricity (this is different from long-term storage, i.e. the amount of time a system can store energy before discharging it). As Maria Chavez at UCS explains, it’s vital to the success of intermittent wind and solar roll-out which needs to store its excess generation for when it’s needed. And as electrification grows it will provide greater grid flexibility and resilience … [Read more...]
Buildings Efficiency: cars have an “eco mode” button. Why not our homes?
Households need the right tools to be able to take control of their real-time energy consumption, says Maximilian Auffhammer at the Energy Institute at Haas. Smart meters are just too crude. They don’t tell you how much energy individual devices are using – fridges, ovens, heaters, EV chargers, TVs, lightbulbs, toasters, etc. You have to work it out yourself by switching devices on and off and seeing the difference. Auffhammer argues if you price … [Read more...]
Record clean-power growth in 2023: is Coal and Gas decline now structurally embedded?
Last year, wind and solar reached a record 12% of global electricity generation, according to think tank Ember’s latest global electricity review. The overall share of all forms of low-carbon electricity rose to almost 40% of total generation. Josh Gabbatiss at Carbon Brief goes through the Ember review which heralds this as the moment fossils began their permanent decline. Ember calls it “structural” and “enduring” because previous declines only … [Read more...]
