When electricity markets have high shares of wind and solar – the goal of many regions around the world – is it more efficient to build a nuclear power plant instead of investing further in more renewable capacity? The answer is yes, according to a study by Machiel Mulder, Xinyu Li and Arjen Veenstra at the University of Groningen. In essence, it’s because nuclear benefits from the high (scarcity) prices when there’s little wind or sunshine. Here … [Read more...]
Post-war Ukraine needs energy independence, decarbonisation and EU cooperation
Energy independence is a choice for some countries. For Ukraine it is a life-or-death necessity, says Andriy Konechenkov, VP of the World Wind Energy Association and Chairman of the Ukrainian Wind Energy Association, in this op-ed. The Russian invasion has exposed the vulnerability of Ukraine’s current energy system. Many of its fossil-fuelled power plants are near the Russian border, exposing them to disruption by the invading neighbour. The … [Read more...]
What can replace Russian gas: modelling Germany’s options on renewables, coal, nuclear, LNG, lowering thermostats
A sudden cut in Russian gas imports means Germany will have to cope with the loss of TWhs. How? Tobias Federico at Energy Brainpool wants decision-makers to get the facts straight. He uses modelling tools to answer this question that is causing fierce debate. The first thing to note is that the loss of gas TWhs (of the order of 100TWh) will be most felt in the provision of heat over winter. Heating systems mostly depends on gas, so intermittent … [Read more...]
Russia-Ukraine and Europe’s energy strategy: a snapshot of a fast-moving crisis
Every day brings news of how Europe’s energy policy is reacting to Russia’s invasion of Ukraine. It’s a big topic and fast moving. Helen Farrell gives a summary of the situation so far. She lists some of the major U-turns at both EU and national levels, the IEA’s ten-point recommendations, the feasibility and repercussions of cutting Russian fossil imports, the prospects for clean energy (solar, wind, nuclear, storage) and our net zero targets. … [Read more...]
Energy Charter Treaty: four ways to amend it and enable green investments
The European Green Deal (EGD) aims to mobilise at least €1 trillion in sustainable investments over the next decade. But the Energy Charter Treaty (ECT) in its current form - designed to protect cross-border investments, enabling those whose energy projects have been shut down to sue nations – is causing fierce debate. The ECT protects all investment alike, but the result has been fossil (and nuclear) investors suing nations that have curtailed … [Read more...]
Russia-Ukraine crisis: reforming the EU ETS is a matter of energy security, says PGE
European leaders are now rushing to make decisions on how to drastically cut dependence on Russian fossil energy imports. Russia’s invasion of Ukraine has exposed Europe’s energy security vulnerabilities like nothing else could have. It also means Europe’s clean energy transition will need an overhaul, and a newly designed optimal pathway created, and fast. Wojciech DÄ…browski, President at PGE Polska Grupa Energetyczna, explains that it must also … [Read more...]
Reducing Europe’s dependence on Russian Oil and Gas: immediate, short and long term strategy
Atlantic Council Global Energy Center experts and associates offer their template for drastically reducing Europe’s dependence on Russian oil and gas. It’s broken down into immediate, short (one to three years) and long term (beyond three years) actions. It’s wide-ranging and comprehensive. Some actions are already in play, including maximising gas storage, ready for next winter. Some are the ramping up of existing plans (clean energy, … [Read more...]
Getting Concentrated Solar Power (CSP) down to $0.05 per kWh
The U.S. Department of Energy is funding research to get the cost of Concentrated Solar Power (CSP) down to $0.05 per kWh. One key element of that research is the materials used to absorb and store the heat energy. Three categories of materials are being looked at: liquid (i.e. molten salt), particle (like sand), and gaseous. NREL is leading the molten salt research, and there are multiple challenges. The salts can corrode the storage tanks and … [Read more...]
EU Taxonomy: why nations are backing Nuclear and Gas
The heated debates over the potential inclusion of nuclear power and natural gas in the EU taxonomy has again exposed the different interests of EU nations. Simon Göss at cr.hub, writing for Energy Brainpool, explains what parameters the EU taxonomy controls, what conditions are attached should the two technologies be classified as sustainable, as well as summarising those national interests and constraints. Critics say neither should be … [Read more...]

Energy Post Quiz 2021
Energy Post has had another strong year in terms of number of debates hosted, readership growth and event attendance. Our readership has grown by 17.16% year on year. We hosted 14 panel discussions (including 3 for ECECP with an average of 20 panellists from all corners of the globe). Together we've reached hundreds of thousands with our event packages. Our thanks to all our authors. Now, with all those parties cancelled due to Covid you have … [Read more...]
Why was Nuclear side-lined at COP26?
James Conca is extremely disappointed that nuclear did not get a serious hearing by negotiators at COP26. Meanwhile in the "Green Zone" (for the general public), the World Nuclear Association had all of its members' applications to establish exhibits rejected. Why? If public opposition is a main obstacle, the nuclear industry should be given an opportunity to argue its case, explain how it is one of the safest energy sources available, and … [Read more...]
Will Wind & Solar confront its 10 challenges? If not, we need Nuclear, CCS, and more
Wind and solar’s impressive cost declines have seen its welcome and rapid emergence. But currently they account for a mere 2–4% of global energy. So these variable renewable energy sources (VREs) must now address 10 big challenges if they are to dominate the energy sector, explains Schalk Cloete in this data-led review. Their cost declines will be confronted and even cancelled by new costs they’ve not yet faced during their low-hanging-fruit … [Read more...]
Germany: can 100% renewable power reduce energy costs within the decade?
A bold report is presented by Thure Traber, Hans-Josef Fell and Sophie Marquitan at Energy Watch Group. It says that a 100% renewable power system for Germany can undercut fossil power within this decade. The authors look at the full cost of fossil power, including subsidies. Importantly, they explain how unit costs will rise further, as demand declines, due to the decreasing utilisation of its expensive infrastructure. Meanwhile, total system … [Read more...]
Nuclear Fusion: U.S. and China race to build world’s first commercial plant
Both the U.S. and China are investing in nuclear fusion, and expecting results. Fusion’s unresolved engineering challenges (getting more power out than you have to put in) must be overcome first. If achieved, it offers the prospect of an almost inexhaustible source of energy. As Dan Yurman explains, this month the U.S. passed a bill that includes $2.8bn for fusion energy-related projects and research. The U.S. Fusion Industry Association said … [Read more...]
