Research into slowing lithium degradation can extend Battery life by 30%

February 2, 2022 by Jennifer Huber

The massive scale-up of batteries is essential to a successful transition. That will be made much easier if the lifetime of existing lithium batteries is greatly extended. With each charge-discharge cycle, the batteries accumulate tiny islands of inactive lithium that are cut off from the electrodes, decreasing the battery’s capacity to store charge. Jennifer Huber at the SLAC National Accelerator Laboratory explains how new research is showing a … [Read more...]

Intelligent, flexible Sector Coupling in cities can double the potential for Wind and Solar

December 16, 2021 by Yong Chen and Dolf Gielen

This week the European Commission tabled the Energy Performance of Buildings Directive (EPBD) which should accelerate the decarbonisation of buildings. Buildings and cities play a key role in the energy transition. And the target high shares of variable renewable power supply will be much more easily achieved if the sectors using them display demand flexibility. In essence, that means using or storing the excess wind and solar generation … [Read more...]

E-fuels for cars are expensive, and pollute the air as much as petrol

December 13, 2021 by Transport & Environment

MEPs and governments are currently deciding on an EC proposal for all new cars sold from 2035 to be 100% zero-emissions. Here, T&E present test results that show e-fuels should not be allowed to replace petrol. T&E are concerned that e-fuels are being promoted as a way to prolong the life of ICE vehicles. But their tests show that e-fuels produce just as much NOx, three times more carbon monoxide, and twice as much ammonia. Though e-fuels … [Read more...]

The 10 big problems with simply replacing fossil cars with electric

December 6, 2021 by Schalk Cloete

The planned rapid transition to electric vehicles has major challenges. Schalk Cloete compiles them into a list of ten, including: preserving our car-centric cities preserves its inefficiencies and societal costs; it works against much of the personal “behaviour change” we need; though BEVs (battery electric vehicles) are better in cities, when infrastructure costs are included they are less efficient than hybrids and modern ICEs for many driving … [Read more...]

Experts from around the world summarise their reaction to the outcomes of this year’s UN climate summit, COP26, including the Glasgow Climate Pact agreed by all 197 countries attending the talks. Each expert covers their area of interest: overall targets, greenhouse gas emissions, fossil fuel finance, nature conservation, transportation, cities and buildings, energy sector transitions, science and innovation, and gender equality. The overall … [Read more...]

Distributed Energy Resources and Smart Grids: an opportunity or a distraction?

November 23, 2021 by Doyob Kim and Alyssa Fischer

Distributed Energy Resources (DERs) are poorly understood by the utilities, explain Doyob Kim and Alyssa Fischer at the IEA. Part of the problem is that new innovations and solutions are coming fast, and policy-makers aren’t creating the incentives and frameworks to make them an imperative. But, done right, the successful integration of DERs into the grid will accelerate electrification, address grid stability, and reduce spending on expensive … [Read more...]

The greenest energy is the energy we don’t use

November 12, 2021 by Martin Rossen

As COP26 comes to a close, Martin Rossen, Senior Vice President, Head of Group Communication and Sustainability at Danfoss reminds us in a powerfully persuasive way why the most direct route to net-zero is managing consumption. Inspired by a glaring omission by Bill Gates in his recent book, Rossen draws our attention to the futility of developing new tech if we don’t prioritise making use of readily available energy efficiency solutions. … [Read more...]

Germany: can 100% renewable power reduce energy costs within the decade?

October 28, 2021 by Thure Traber, Hans-Josef Fell and Sophie Marquitan

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...]

Concern over auto job losses as Europe transitions to EVs

October 22, 2021 by Benjamin Wehrmann and Sören Amelang

The state premier of Lower Saxony, home of Volkswagen, says he would not tolerate a large-scale reduction in staff at Germany’s largest carmaker. There is talk of axing 30,000 VW jobs nationwide, though messages have been mixed. Benjamin Wehrmann and Sören Amelang at Clean Energy Wire look at the latest news, then summarise the implications of the EV transition for the auto industry across Europe. Highlights include the observation that a Tesla … [Read more...]

Compact voltage converters for integrating new DERs into the grid

October 20, 2021 by NREL

The switches and converters needed to plug new clean energy technologies into the grid are going to be needed soon. The cheaper and smaller they are, the easier it will be to cope with the wide range of solutions coming down the pipe. NREL and its partners are building a megawatt-scale prototype converter that could fit the bill. They will be 1/5th the size and 1/10th the weight of existing alternatives: small enough to place almost anywhere. … [Read more...]

IEA WEO 2021 message to COP26: 40% of clean energy goals will cut costs

October 15, 2021 by Simon Evans

The IEA’s latest World Energy Outlook was published on Wednesday. This year’s WEO-2021 is released earlier than usual to inform COP26 and, for the first time, is available for free to ensure the widest possible audience. Simon Evans at Carbon Brief offers his summary of the 386-page report, quoting relevant numbers and charts. He first points to the new scenario, Net-Zero Emissions by 2050 (NZE), as the IEA’s recognition that this is what … [Read more...]

Clean transport in Europe: key trends to watch out for

October 11, 2021 by Thomas Earl

T&E’s quarterly trends series gives a snapshot of the key developments that will define the future of clean transport in Europe. And what Europe does – given it wants to lead this field – should influence what happens worldwide. T&E’s Thomas Earl brings attention to four issues. First, proven progress in this major sector makes it a contender for a significant role in Europe’s new industrial strategy. It ranges from battery and … [Read more...]

New cooling system for inverters brings electric Heavy-Duty Trucks closer

October 6, 2021 by Rebecca Martineau

39% of greenhouse gas emissions in the transport sector comes from heavy-duty trucks. Commercial batteries struggle to deliver enough power to make electrification feasible for heavy-duty applications. Rebecca Martineau at NREL explains how a working prototype, developed with the heavy machinery manufacturer John Deere, is now getting a 378% increase in power density. The key to the innovations rests on a state-of-the-art thermal management … [Read more...]

Next German government’s climate and energy plans: what will Olaf Scholz do?

October 4, 2021 by Kerstine Appunn and Benjamin Wehrmann

Olaf Scholz led Germany's Social Democrats (SPD) to an unexpected win in the 2021 elections held in September. He now needs to finalise a coalition with the Green Party and the pro-business FDP before forming a government and becoming chancellor. Like his predecessor Angela Merkel, Scholz has said he wants to become a "climate chancellor". Kerstine Appunn and Benjamin Wehrmann at Clean Energy Wire try to understand what his climate and energy … [Read more...]

Nanochemistry breakthrough could lift energy density of batteries by factor six

September 22, 2021 by Stanford University

Finding new ways for batteries to increase the charge they can store will lift their energy density. Researchers at Stanford University have developed an alkali metal-chlorine battery that stores six times the charge of today’s commercially available lithium-ion batteries. Until this breakthrough, a high-performance rechargeable sodium-chlorine or lithium-chlorine battery has been impractical because chlorine is too reactive to convert back to an … [Read more...]
