The IEA’s report released earlier this year, “Hydrogen in North-Western Europe: A vision towards 2030”, welcomes the fact that the six countries analysed - Belgium, Denmark, France, Germany, the Netherlands, Norway and the UK – have the ambition to build a hydrogen economy. They are Europe’s major hydrogen producers and consumers, have major ports that already service this sector, have natural gas infrastructure that can be repurposed, and access … [Read more...]
Germany: will the end of feed-in tariffs mean the end of citizens-as-energy-producers
Germany’s feed-in tariffs ran for 20 years. The guaranteed electricity price and connection to the grid incentivised ordinary citizens and communities to invest in smaller scale solar, biomass and wind generation for their homes and local areas. But that guaranteed price is now too expensive, and so the tariffs are ending and lowest-bid auctions are taking over. It’s the bigger players who are winning those auctions, and some of the existing … [Read more...]
Case study Italy: Optimising emissions cuts means we’ll need “grey” and “blue” Hydrogen too
Europe is committing to hydrogen. The ideal is “green” hydrogen, produced from renewable energy alone. Carlo Stagnaro at Istituto Bruno Leoni analyses emissions and costs in Italy to make the case for policy-makers to consider including “grey” and “blue” hydrogen in their strategies too. Because grids are far from green today, a new wind and solar plant will reduce more emissions by feeding the grid than by making hydrogen. “Grey” hydrogen, … [Read more...]
What patents tell us: which countries, what sectors, are the clean energy innovators?
Today’s solutions cannot give us a successful transition on their own. That’s why the innovations coming down the pipeline are so important. One way to measure what, and who, is innovating is to look at the number of patents being filed for low carbon energy (LCE), explains Sean Fleming writing for the World Economic Forum. He summarises the latest report from the European Patent Office and the IEA, “Patents and the energy transition: Global … [Read more...]
Does new German target mean Coal gone by 2029, Renewables 65% by 2030?
The stiffer emissions targets introduced this month to Germany’s Climate Protection Law - CO2 emissions from the energy industry must fall to 108 Mt by 2030 instead of 175 – point to an even earlier coal phase-out date of 2029, with renewables generating 65% of electricity by 2030. The existing plan had meant coal must be gone by 2038. Michael ClauĂźner, Carlos Perez-Linkenheil and Simon Göss at Energy Brainpool explain why, using their modelling … [Read more...]
The IEA explains its new “Net-Zero Emissions by 2050” roadmap
Today the IEA publishes its new special report, “Net Zero by 2050: a Roadmap for the Global Energy Sector”, its deepest dive so far into what’s needed for a successful global transition. It analyses the options as well as the socio-economic, behavioural and environmental impacts they will have globally. Here, Laura Cozzi (Chief Energy Modeller) and Timur GĂĽl (Head of the Energy Technology Policy Division) at the IEA summarise the key principles … [Read more...]
The standard models overestimate the cost of the low carbon transition
Why have forecasts for new low-carbon energy consistently underestimated their cost reductions? The IEA has, famously, repeatedly had to raise its estimates for solar’s contribution every year since 2009, and now describes it as the “cheapest electricity in history”. Writing for Carbon Brief, Alexandra Poncia at Arup and Paul Drummond and Michael Grubb at University College London explain that standard models focus on “technology-push” policies, … [Read more...]
New U.S. Offshore Wind target: from standing start to 30GW by 2030
In March, the Biden administration announced a bold target to deploy 30GW of offshore wind capacity by 2030. Until now, offshore wind’s rise has been driven almost exclusively by Europe and China. The U.S. accounts for just 0.1% of the world’s installed capacity (versus 17% for onshore wind). Why the hold up, given the U.S. could require up to 400GW of offshore wind by 2050? As Stephen Naimoli and Nikos Tsafos at CSIS explain, offshore costs … [Read more...]
What is making Denmark a decarbonisation success? Policy, society, geography
Denmark is proving itself to be a decarbonisation leader, happy to turn its back on its history of oil and gas production and heavy reliance on coal. Its ambitious goal of cutting GHG emissions by 70% by 2030 makes it a global policy frontrunner, second only to Finland which aims to be climate neutral by 2035. Thibault Menu references his report for IFRI that asks what makes Denmark special. It has a long tradition of  providing stability and … [Read more...]
Outlook USA: even with battery costs, Wind and Solar can undercut Coal and Gas by 2023-24
IEEFA has published its U.S. Power Sector Outlook 2021. Its authors, Dennis Wamsted, Seth Feaster and David Schlissel summarise and explain the projections. They say that coal and gas are set to become the biggest losers as renewable generation climbs quickly. The future for wind and solar – coupled with storage to address intermittency - is looking very good. They present estimates from NextEra (the largest renewable energy developer in the … [Read more...]
Public opposition and grid integration costs: the two limiting factors for Wind?
Are we heading for an over-reliance on wind? With wind generation costs continuing to drop dramatically, Schalk Cloete takes a data-driven look at the obstacles wind will face as its contribution to the global energy mix (a little over 2% today) keeps rising. In the main, it is grid integration and public opposition to very visible turbines – and they are related. Putting turbines out of sight and offshore will increase transmission costs. And … [Read more...]
Understanding battery costs better: Li-ion costs have dropped 97% in 30 years
There are two revelations here. First, quite how dramatically lithium-ion battery costs have dropped since 1991 – by 97%. Second, that nobody has been able to agree on how big that drop has been. But agreement on that number – and an established procedure to therefore make good forecasts - is vital for policy makers and related clean energy players. They need to know how much of a role batteries can play in the electrification of transport as … [Read more...]
“The Role of the EU ETS in Decarbonisation to 2030” [written summary of the panel discussion]
Here you can read a summary of the online discussion from March 19th 2021 on the current debate over the review of the EU ETS. The full video is available here. Of primary concern for fossil-dependent lower income nations is the carbon price rising so high that it reduces available budget for investment in clean energy. If that happens there’s clearly a problem. The counter argument is that there are other funding mechanisms available, and more … [Read more...]

How to keep winter ice off a Wind Turbine’s blades
Nearly 800GW of wind power have been installed worldwide so far, with plenty more to come. But the Texas freeze in February showed how vulnerable wind turbines are to ice. Hui Hu at Iowa State University summaries his team’s research into solving a problem that can cut generation by 20% or even shut down turbines completely. He explains why existing de-icing solutions for airplane wings offer only a partial solution. Metal airplane wings can be … [Read more...]
