Upcoming EU policies intended to cut shipping emissions would add just a few cents to the cost of goods all the way from China, says an analysis by T&E. Extending carbon pricing to shipping and mandating small amounts of green e-fuel use by 2030 will mean a pair of trainers would cost just âŹ0.003 more, a television âŹ0.03 and a refrigerator up to âŹ0.27 more. Itâs because final costs are not very sensitive to fuel costs. The more startling … [Read more...]
Imposing a $50/barrel tariff on Russian oil is the best sanction
Is there a way to impose sanctions on Russia that cuts its revenues without causing fossil fuel prices to balloon? The current strategy has seen oil prices rise to $120/barrel by mid-June, so although volumes are down Russia has seen no reduction in revenues. In other words, it has not achieved its objective, says Edward Chow at the Center for Strategic and International Studies. Instead, he argues for imposing a big import tariff â like … [Read more...]
Interpreting the Paris Agreement: the 1.5C and 2C targets are not two different options
Carl-Friedrich Schleussner and Gaurav Ganti at Humboldt University of Berlin, writing for Carbon Brief, want to clear up confusion over the 1.5C and 2C pathways. Their concern is that some people are interpreting the Paris Agreementâs wording as two separate targets, one simply better than the other. But they should not be seen as two different options. The objective of âwell below 2Câ must be seen by modellers and policy-makers as a clear … [Read more...]
The Mining industry should simultaneously be testing for Geothermal potential
In Nevada alone, the mining industry drills over 2,000 exploration holes per year. They do so to the depths needed to also verify whether the location is suitable for geothermal energy, so it makes sense for them to assess suitability not just for minerals but for geothermal, explains Ryan Horns writing for NREL. Leveraging that data, knowledge, and expertise will expand the geothermal exploration workforce, increase the rate of geothermal … [Read more...]
âNew Collective Quantified Goalâ: how much should rich nations pay developing nations for climate mitigation?
Is the $100bn a year promised by rich nations to developing ones to assist their climate mitigation plans enough? Almost certainly not, explains Mahlet Eyassu Melkie at Rocky Mountain Institute. That number was pretty much plucked out of the air for political reasons. To come to an evidence-based number, a great deal of assessment, analysis and finally agreement is needed internationally. That process is called the New Collective Quantified Goal … [Read more...]
Implementing Polandâs national Recovery and Resilience Plan
How should Poland implement its national Recovery and Resilience Plan (RRP)? Sonia Buchholtz at Forum Energii outlines some important answers. First, a deep analysis of the challenges and assessment of the solutions and reforms must start now. Buchholtz says though the directions set out in the RRP are correct, the details are out-of-date. Policy reforms and more ambitious targets are needed in all the main areas: energy efficiency and heating; … [Read more...]
Global map of the future cost of clean Hydrogen production in 2030 and 2050
The worldâs commitment to hydrogen needs an assessment of which regions can make it the cheapest. Herib Blanco at IRENA and Jacopo de Maigret at Fondazione Bruno Kessler describe their study of the range of factors that affect the future cost and therefore the potential for clean renewable hydrogen, estimated for 2030 and 2050. The main drivers are the capital cost of the renewable generation and the electrolyser, the cost of capital, and the … [Read more...]
4 ways to cut whole system electricity costs with flexible Demand Side Management
Right now, energy system costs are driven by generation capacity, infrastructure upgrades, network reinforcements, curtailment and constraint payments, and imbalance costs. Whatâs missing is the investment in a raft of demand side management assets that are ready to go but are not part of the market, therefore not rewarded, and therefore not being invested in. Laura Sandys at Energy Systems Catapult, writing for WEF, explains why flexibility must … [Read more...]
New thermophotovoltaic cells turn heat into electricity more efficiently than a steam turbine
Over 90% of the worldâs electricity comes from heat-generating power plants using coal, natural gas, nuclear energy, and concentrated solar energy. Steam turbines have always been the standard for converting that heat into electricity. On average they are only 35% efficient, with moving parts that cannot cope with temperatures above 2,000 degrees Celsius. Jennifer Chu at MIT describes new research, in collaboration with NREL, that has led to a … [Read more...]
The light bulb transition: when standards and subsidies promote sub-optimal technologies
This article is for those who want to understand the importance of timing: when is the right time to impose new standards and start/stop subsidies, to optimise the pathway to maximum efficiency? The light bulb transition of the last two decades is one of the successes of energy efficiency: from the old incandescents (15 lumens/watt) to halogen incandescents and CFLs, and then, finally, to LEDs (80 lumens/watt and prices falling 90% in ten years). … [Read more...]
If Russia cuts its gas supplies to Germany, what happens next?
Replacing Russian pipeline gas to Europe in the short term is much more difficult than finding alternative sources for coal and oil. Itâs why the EU hasnât 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...]
Russia-Ukraine: modelling the consequences for the European electricity market to 2050
Alex Schmitt, Christoph Kellermann, Calvin Triems and Huangluolun Zhou at Energy Brainpool have used their modelling tools to update their predictions of how the European electricity market will develop over the next 30 years, given a target of 99% emission-free generation in 2050. Projections are made on generation (mix and volumes) and price. The big change from their last predictions is the Russia-Ukraine war and Europeâs determination to ramp … [Read more...]
China tariffs: Bidenâs plan to unblock domestic Solar manufacturing
The U.S. solar industry has been caught up in the wider tariff disputes with China, a key exporter of solar panels and components. The Solar Energy Industries Association estimates hundreds of projects have been cancelled or delayed, totalling more than 50GW (thatâs over twice the total US solar installations of 2021), putting 100,000 jobs at risk (almost half the solar workforce). John Rogers at UCS explains what the Biden administration is … [Read more...]
Next-gen Solar farms that work at night, in the rain, and self-clean
With the worldwide roll-out of solar, raising the efficiency of energy conversion isnât just about the materials science of PV cells. Douglas Broom, writing for the World Economic Forum, runs through three âadd-onâ innovations. Researchers have found a way to generate electricity in the dark as panels cool during the night. A low-cost thermoelectric generator works using the temperature difference between the cooling solar panels and the … [Read more...]
EUâs latest sanctions on Russian Oil: what are they and will it work?
On June 3, the EU agreed an embargo on Russian crude oil and petroleum products. Ben Cahill at the Center for Strategic and International Studies looks at the details of the latest sanctions imposed in response to Russia's ongoing invasion of Ukraine, and assesses the possible consequences. The aim is to cut oil imports from Russia by 90 percent by February 2023. A critical part of the sanctions is a ban on providing shipping insurance to Russian … [Read more...]
