EU Member States have inadvertently supported with their own subsidies the renewable energy targets of other Member States, a practice that violates EU internal market rules, explains Kim Talus at UEF Law School. He looks at how Denmark subsidised Danish biomethane producers who exported to Sweden, where Swedish consumers were benefitting from subsidies already. This promoted Danish biomethane producers at the expense of rivals. In December 2022 … [Read more...]
World’s biggest plane to carry Offshore-Wind sized blades to “inaccessible” onshore destinations for first time
It looks brilliantly simple. Why are onshore wind turbines smaller than offshore ones? Because you have to move them to their location by road, over bridges, through tunnels and around curves. That limits their size. As Michael Purton, writing for WEF, explains it’s why the company Radia is building the world’s biggest aeroplane called WindRunner (12 times the volume of a Boeing 747), big enough to carry turbine blades over 100m long. And the … [Read more...]
Basic energy access reverses for first time in a decade, after good progress since 2015
After good progress globally since 2015, basic energy access reversed in recent years for the first time in a decade, says the IEA. The 2024 edition of “Tracking SDG 7: The Energy Progress Report” measures progress on “strategic development goals” that include universal access to electricity and clean cooking, doubling historic levels of efficiency improvements, and substantially increasing the share of renewables in the global energy mix. The … [Read more...]
The Fossil Fuel system wastes 2/3rds of its energy before it gets to you. Inefficiency is driving it out (not just emissions)
Today’s fossil energy system is very inefficient: almost two-thirds of all primary energy is wasted in energy production, transportation, and use, before fossil fuel has done any work or produced any benefit. That’s almost 400 EJ wasted, worth over $4.5tn, or almost 5% of global GDP. Two activities - fossil fuel power plants and internal combustion engines - are responsible for almost half the energy waste globally. Daan Walter, Kingsmill Bond, … [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...]
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...]
The EU’s inaugural Hydrogen subsidy auction. What have we learned?
At the end of April, the winners were announced of the first pilot auction to allocate subsidies for EU hydrogen production via the European Hydrogen Bank. The winning bids were between €0.37 and €0.48 per kg, much lower than the €4 – €6 per kg estimated “green premium” cost gap between renewable hydrogen and fossil hydrogen in Europe. The low bids mean companies applied for fewer subsidies than needed to bridge that “green premium” gap because … [Read more...]
What China, Germany, and Texas tell us about Capacity Adequacy
As intermittent renewables penetrate further into the grid mix, reliable firm power generation is needed for whenever there is a shortfall. But back-up power, by its nature, has unreliable utilisation rates. And up-front costs for new plants are high, be they gas-fired plants, coal, nuclear, or large-scale storage. That makes future profitability uncertain, and private investors nervous. Hence the need for “capacity mechanisms” that guarantee … [Read more...]
10% of global GDP growth came from the new Clean Energy economy in 2023
The clean energy economy is making its mark on global GDP, explain Laura Cozzi, Timur GĂĽl, Thomas Spencer and Peter Levi at the IEA. It accounted for 10% of global GDP growth in 2023, primarily through three activities: manufacturing of clean energy technologies, deployment of clean power capacity, and clean equipment sales. Here, the authors present the in-depth results for four of the largest economies: the U.S, the EU, China and India, which … [Read more...]
Strict rules stop Green Hydrogen production diverting clean power from the grid. What are they?
Green hydrogen must be made from green electricity. But the electricity used for making it must fulfil stricter requirements than conventional green electricity. Matthis Brinkhaus at Energy Brainpool describes the criteria by which hydrogen can be designated as 100% renewable: Additionality; Additionality Plus; Temporal correlation, simultaneity; Geographical correlation, regionality. Brinkhaus points at where exceptions can be made, and where … [Read more...]
Can the six Gulf nations meet their ambitious Renewables deployment plans by 2030?
The six Gulf Cooperation Council (GCC) countries (Bahrain, Kuwait, Oman, Qatar, Saudi Arabi, UAE) have all set themselves ambitious renewable energy targets to meet in the next ten years. They are some of the sunniest countries in the world, and existing projects have set records for low solar power costs. But they have a long way to go. In 2022, GCC renewable capacity was 5.7GW, primarily solar PV, out of 165GW of total generating capacity, … [Read more...]
Europe’s cross-border Interconnectors: how JAO auctions optimise energy flows, prices
Interconnectors allow for cross-border flows of energy between two markets that would otherwise not be connected. Through an economic convergence between supply and demand, the cheapest marginal producer located anywhere in these two markets should be able to set market prices. As Jean-Baptiste Vaujour at the Emlyon Business School explains, the central question is to find an optimal allocation of the scarce interconnection capacity between the … [Read more...]
New Offshore Wind projects: is permitting being slowed by evidence from “grey literature”?
Offshore wind is the new frontier of clean energy generation. The permitting process depends on policymakers’ evaluation of the impact assessment evidence. As Claire Szostek at the Plymouth Marine Laboratory explains, that evidence has two sources: primary and “grey” literature. “Primary literature” comes from structured peer-reviewed scientific journals. “Grey literature” includes all other types of reports and evidence published freely. The … [Read more...]
Euro 2024: what’s being done to make it “the most sustainable football championship of all time”?
UEFA and the German Football Federation (DFB) have promised that EURO 24 will be “the most sustainable European championship of all time.” As Ruby Russell writing for CLEW explains, plans extend across 10 energy-hungry stadiums, travel to and between 51 games (80% of emissions!), merchandise and catering. To tempt people off budget airlines, train fares are being subsidised and extra trains scheduled in. There are plans to use renewable power in … [Read more...]
Financing Europe’s cross-border Interconnectors to deliver energy security, lower prices: a look at incentives and policies
The EU and its Member States are building out interconnectors to improve security of supply and affordability of electricity through the physical and economic linking of national energy markets into a single, synchronised European market. But each interconnector is expensive, complex and therefore risky. They can span long distances or natural obstacles such as mountains or seas. Significant network planning and adaptation is needed to account … [Read more...]
