EU Solar has avoided 20bcm of gas imports and saved €29bn

by

Solar generation in the EU has avoided the import of 20bcm of gas that would have cost €29bn, explains PaweƂ CzyĆŒak at Ember, writing for Carbon Brief. The new solar power added since 2021 alone avoided €6bn of gas imports. Record EU solar generation increased by 28% in the summer of 2022, compared with the same period a year earlier. And it’s growing very quickly, with a consistent 15% year-on-year increases in installed solar capacity – from … [Read more...]

Is a Carbon Tax the best way to decarbonise the Grid?

by and

Severin Borenstein at the Energy Institute at Haas and Ryan Kellogg at the University of Chicago question whether carbon pricing is the best way to decarbonise the electricity grid. The authors did an empirical analysis of all of the fossil plants in the US. It shows that a CES (clean electricity standard) or zero-emissions subsidies would close down fossil plants in almost the same order as a carbon tax. So using alternative policy tools can … [Read more...]

Carbon Capture is a risky decarbonisation pathway: 13 flagship projects reviewed

by

The debate around the effectiveness of carbon capture (you can register now for our CCUS session on Wednesday at 10.45 - Editor) has led to polarising views. Although the first implementations began 50 years ago, serious efforts to capture large volumes cost-effectively are in their infancy and unproven at scale. Is it, given time and support, a solution to excess emissions worldwide? Or is it a distraction that will allow fossils to be used yet … [Read more...]

Event Summary: Building GW-scale Offshore Wind in the Baltic Sea

by

Here we provide a written summary of the panel discussion “Wind of Change or Change of Wind? The future of Baltic Sea offshore investments” held on 12th September 2022 in Brussels. It’s a full summary of the 90 minute discussion (including audience questions), but it begins conveniently with a summary of the highlights. The Baltic Sea has the potential to develop over 90 GW of offshore wind capacity. The Russian invasion of Ukraine has delivered … [Read more...]

Fossil fuel producers can decarbonise by exporting Electricity, Hydrogen, and Steel

by

The compelling reason why fossil fuel producers will be needed even beyond 2050 is that they currently provide over 80% of global energy, and 90% of the world’s population still needs the wealth creation that energy delivers, says Schalk Cloete. Given that, he summarises his co-authored paper that takes a close look at how a fossil exporter, Norway, can trade with an importer, Germany, while decarbonising. The modelling focusses on electricity … [Read more...]

As spot market electricity prices break all records, what is the prediction for winter?

by

Spot market prices for electricity have been breaking all records, as European leaders and their ministers intensify their discussions on how to deal with the crisis. Simon Göss at cr.hub, writing for Energy Brainpool, starts by explaining how the markets work, noting that price rises are indeed being driven by fossil prices and not CO2 certificates. Göss looks at how prices have climbed in Germany, France, the Baltics and Spain, and how the … [Read more...]

Electricity market re-design should focus on the root cause of the crisis, Europe’s dependence on fossil fuels

by

Amidst the perfect storm of the pandemic, war in Ukraine, and extreme weather events, Bruce Douglas at Eurelectric urges us all not to lose focus on our decarbonisation targets. Energy savings, electrification and renewables are more important than ever to help reduce dependence on fossil fuels. Douglas explains that Europe’s electricity sector remains totally committed to the drive towards clean energy, citing examples. He summarises the … [Read more...]

Modelling green Ammonia and Methanol in 2050. It will be expensive

by

Schalk Cloete starts by explaining that it is unrealistic to expect clean electrification to carry the main burden of energy supply. Even a fast roll out will be constrained by a range of infrastructure and cost limitations. Hence our continued dependence on fuels, with their high energy density and ease of transport. Those fuels will have to be made clean, so he summarises his co-authored papers that model the cost of green and blue ammonia and … [Read more...]

Don’t cap gas prices for consumers. It won’t reduce demand. Instead, subsidies must reward cuts in gas use

by

European nations are considering capping the price of gas that consumers pay, a subsidy that governments will pay for, to ensure households don’t freeze this winter. Daniel Gros at CEPS warns that this strategy will remove the incentive for consumers to cut their gas use, keeping international market prices high. Instead, governments should incentivise a reduction in gas use. Gros has modelled two strategies. The first is to pay households for … [Read more...]

Deep Geothermal: accessing 500°C for steam turbines. Can it make coal, gas, nuclear redundant?

by

The concept of “deep geothermal” is very simple. Dig deep enough, like 20km, to access a permanent reservoir of 500°C of heat. There, you generate the steam to power your turbines. The digging of a stable hole and getting the steam to the turbine is the big engineering challenge. But if you find a way that allows you to do it anywhere in the world (i.e. not limiting yourself to existing geological formations), nobody will ever need other … [Read more...]

If Russia cuts off its gas supply can we achieve EU storage targets for winter?

by

Calvin Triems at Energy Brainpool summarises their analysis of whether and how Europe can achieve its storage targets for 2022. There are four scenarios: “Base Case”; “[email protected]%” where there’s no change to Russia’s mid-June gas flow cut to 40%; “[email protected]% + No Freeport” where the unexpected fire in early June at the U.S. Freeport LNG terminal remains unresolved for months; “[email protected]% + No Freeport” where Russia cuts off supply … [Read more...]

Methane emissions reach unexpected new highs. Is climate change causing a runaway effect?

by

Simon Redfern at Nanyang Technological University, Singapore summarises his co-authored study that says methane emissions are four times more sensitive to climate change than that estimated in the latest IPCC report, which was only published in February 2022. The study follows the observation that, despite the pandemic stalling the world economy, methane emissions have reached new highs. Not because methane emissions have risen but because … [Read more...]

Record global clean energy spending, but it’s still not enough and costs are rising

by

Since 2020, clean energy investment has grown by 12% per year – it was only 2%/year during the five years after the 2015 Paris Agreement. That boost is the main reason why total global energy investment is set to reach $2.4tn in 2022, according to the latest “World Energy Investment” report from the IEA. It’s very good news that spending on solar PV, batteries and EVs is now growing at rates consistent with reaching global net zero emissions by … [Read more...]

Will price caps on Russian oil work? Three experts debate

by , , and

Whatever the G7 does, the objective is to cut revenues flowing into Russia, not oil flowing out. And whatever the sanctions, getting compliance from neutral and pro-Russian countries will need a strong positive incentive. Hence the idea of a price cap which would keep prices low. Here, three experts – Edward Fishman and Brian O’Toole at the Atlantic Council, and Mark Mozur at S&P Global Commodity Insights (with background by Atlantic … [Read more...]

If Russia cuts its gas supplies to Germany, what happens next?

by

Replacing Russian pipeline gas to Europe in the short term is much more difficult than finding alternative sources for coal and oil. It’s why the EU hasn’t banned Russian gas. But what if Russia cuts off the supply? Benjamin Wehrmann at Clean Energy Wire looks at what the consequences and options are for Germany. Though Germany aims to wean itself off Russian supplies almost entirely by 2024, a sudden cut would have serious consequences. Storage … [Read more...]
