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?
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
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
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
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
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
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?
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
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...]
Giving car manufacturers e-fuel credits will slow the rise of EVs
Transport & Environment (T&E) explains why e-fuel credits should not be included in the EU’s CO2 standards for new cars. If they are, it would give carmakers the option to claim an ICE vehicle as low- or zero-emission. But carmakers have no control over what fuel their customers put in their cars, making the regulation impossible to monitor. That opens the door to double-counting emission reductions with other existing regulations (Fuel … [Read more...]
Can Aluminium-air batteries outperform Li-ion for EVs?
Aluminium-air (Al-air) batteries for cars are an innovative technology that automakers and policy-makers should take a close look at, say Helena Uhde and Veronika Spurná at ECECP. Although a battery, they behave more like an engine: the fuel is the aluminium which reacts with the air via an electrolyte to produce electric power. Al-air has big advantages over a lithium-ion battery, the favoured choice for EVs. It has a travel range similar to … [Read more...]
EU “Fit for 55”: how it impacts the EU ETS to accelerate emissions reductions
Christoph Kellermann, Lun Zhou and Simon Göss at Energy Brainpool explain how the EU’s new “Fit for 55” proposals, released in July, will impact the EU Emissions Trading Scheme (EU ETS), hailed as one of the most effective ways of reducing emissions. The authors cover the changes to the existing ETS, the planned new ETS for road transport and buildings, the controversial Carbon Border Adjustment Mechanism (CBAM), and the new CO2 standards for … [Read more...]
We’re not costing energy correctly: reward clean energy optimisation, not maximum generation
Laura Sandys at Energy Systems Catapult says policy makers today are too focussed on rewarding clean energy generation, in other words supplying as much energy as possible. With that comes a focus on reducing the cost of the energy generated. But how about reducing demand? Demand optimisation should be equally rewarded: efficiency, non-generation demand management (even at the household level: think EVs and heat pumps), and any assets that … [Read more...]
EU: Slow-moving CO2 targets for cars put EV battery boom at risk
Europe’s battery manufacturers are positioning themselves to be global leaders. Their project pipeline will be enough to power a new European car fleet that is 75% battery-electric by 2030. That’s 38 European gigafactories by 2030 (fully funded, part-funded and proposed), €39.5 billion worth in investments, creating 44,000 direct factory jobs. But existing CO2 emissions cut targets imposed on car manufacturers – a leading driver of demand for … [Read more...]
China’s energy system: record renewables expansion, but coal still dominates
Lara Dombrowski and Simon Göss at Energy Brainpool give the latest headline figures for China’s energy system. In 2020 electricity generation in China went up by 298 TWh – an increase equal to 60% of Germany’s total. That year, renewables capacity increased more than ever before. That made China responsible for nearly 50% of global renewable capacity additions. But China has higher CO2 emissions than all the OECD countries combined. And continued … [Read more...]
