How do you double or triple your existing power transmission capacity when costs are rising and you face local opposition to the disruption? Zach Winn at MIT describes a new innovation that uses superconductors designed to transport five to 10 times the amount of power of conventional transmission lines, using essentially the same footprint and voltage level, carried on otherwise standard overhead lines. The superconducting cables (with much of … [Read more...]
Upgrade the grid, or avoid by incentivising flexibility? Electricity demand mapping can tell you what to do
Power grids across the world need upgrading to accommodate the rapidly rising amount of electricity being generated. Without it, it is a serious bottleneck to the transition to clean fuels. Sheridan Few at the University of Leeds summarises his co-authored study that creates a map of where upgrades are most needed in the UK. The map’s purpose is twofold. Firstly, it predicts where power consumption will rise the most and the upgrades are … [Read more...]
How to handle rapid Grid load growth: Data Centres can set the template for EVs, Buildings, new Industry
Due to their growing power demand, data centres can set a precedent for how to handle rapid load growth in a way that supports the grid and ensures reliable, resilient, carbon-free electricity. In other words, they can set the template for the coming surges in demand from EVs, buildings electrification, and the new rich-world policies of onshoring industry and manufacturing, explain Alexandra Gorin, Roberto Zanchi and Mark Dyson at RMI. Big, … [Read more...]
A global review of Battery Storage: the fastest growing clean energy technology today
The IEA report “Batteries and Secure Energy Transitions” looks at the impressive global progress, future projections, and risks for batteries across all applications. 2023 saw deployment in the power sector more than double. Strong growth occurred for utility-scale batteries, behind-the-meter, mini-grids, solar home systems, and EVs. Lithium-ion batteries dominate overwhelmingly due to continued cost reductions and performance improvements. And … [Read more...]
Big Data’s huge power demand can migrate globally, instantaneously: implications for planning regional capacity and markets
Something is going to make the planning of regional power generation and associated markets even harder: the ability of big data users to shift their demand across the globe quickly, based on price. Ira Joseph at CGEP peers into the near future to ask some difficult questions. When such power demand can “at the push of a button” migrate long distances, how do you make predictions for local capacity needs? And today, market design in most … [Read more...]
France’s Macron wants to build 14 new Nuclear reactors by 2050. 6 is more realistic
France's President Macron is talking about a nuclear renaissance, after years of uncertainty over its future. The goal is to build 14 new reactors by 2050. But Jonathan Bruegel at IEEFA says this is unrealistc. France’s nuclear sector has much to recommend it. It produces up to 80% of the country’s total power generation, the highest share of nuclear in the generation mix anywhere in the world, and CO2-free. However, France hasn’t built a nuclear … [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...]
EU’s fossil fuel CO2 emissions drop to levels last seen in the 1960s
The EU’s CO2 emissions from fossil fuels (including power generation, industry and transport) dropped 8% in 2023 year-on-year, reaching levels last seen in the early 1960s, reveals an analysis by CREA. More than half of that decline came from an impressive 25% year-on-year reduction in CO2 emissions from power generation. The cleaner electricity mix is thanks to the continuous rise of wind and solar as well as a rebound in hydropower and nuclear. … [Read more...]
Building and financing the expansion of Europe’s electrical interconnection market
In the first of a series of four articles covering the expanding market for electrical interconnections in Europe, Jean-Baptiste Vaujour at the Emlyon Business School sets the scene by presenting the main points and current developments around the difficulties of building and financing these assets. Interconnectors allow power to be sent across borders to meet the shortfall where supply is not meeting demand. For example, European electricity … [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...]
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 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...]
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...]
