For transport, biofuels have lower emissions than gasoline/petrol, but EVs will have the lowest emissions of all. Hence the opposition to those biofuels, along with objections to the valuable cropland used to make the ethanol. But the overall advantage depends on the speed of transition to EVs charged with clean electricity. Now, a calculation has been made of the amount of agricultural land preserved for global food production - or kept as … [Read more...]
Grid Distribution Systems: access to usage data is uncovering the optimal design for future electrification
The more efficient a distribution grid is, the less likely other potential supply bottlenecks (from lithium for batteries to trained electricians) will slow the transition to greater and greater electrification. State-of-the-art modelling of future grids is already happening, but the robust modelling of the distribution system is conspicuously missing because good data are notoriously hard to find, says Meredith Fowlie at UC Berkeleyâs Energy … [Read more...]
Record global clean energy spending, but itâs still not enough and costs are rising
Since 2020, clean energy investment has grown by 12% per year â 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 âWorld Energy Investmentâ report from the IEA. Itâs 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...]
Event summary: â45% RES by 2030: EUâs latest investment challenge to DSOsâ
Sara Stefanini provides a written summary of our panel discussion held on Thursday June 30th 2022. Itâs a full summary of the 90 minute discussion (including audience questions), but it begins conveniently with a summary of the highlights. Investment in and the modernisation of the electricity distribution grid is one the biggest challenges the EU has to overcome in the next decade. Itâs a âŹ400bn investment challenge by 2050 says Eurelectric, an … [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...]
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...]
Manifesto: fit-for-purpose flexible grids for the clean electrification of Europe
The integration of new clean generation sources on top of the increase in electrification of industry, e-mobility, and heating and cooling means grid investment must be made a priority. Anything else will leave deployment-ready solutions waiting, slowing down the transition. The backdrop is that over one third of the EUâs grids are already more than 40 years old. Eurelectric has produced a manifesto, âConnecting The Dotsâ, that estimates … [Read more...]
Critical minerals: price spikes are affecting Wind, Solar, Batteries, EVs
A wide range of critical minerals are needed for the energy transition. Tae-Yoon Kim at the IEA summarises the reasons why we should expect this to be a year of price spikes due in the main to the Russia-Ukraine war and post-lockdown supply chain bottlenecks. So severe is the problem that the long record of declining costs in clean energy technologies like solar, wind, batteries and electric vehicles is being reversed. Although these crises will … [Read more...]
Event Summary: âCHINA: Carbon Neutral by 2060 â Innovationâ
Here are the highlights of our 2-day 4-session workshop âCHINA: Carbon Neutral by 2060 - Innovationâ, compiled by Sara Stefanini. Itâs a quick and efficient way for readers to see the main points made by our expert panellists. Held at the end of May, it was the fourth of our EU-China workshops since the first was held in November 2020, produced for the EU China Energy Cooperation Platform (ECECP). As always, leading speakers from the EU, major … [Read more...]
How the U.S. can meet its target of halving emissions by 2030
Writing for Carbon Brief, John Bistline at the Electric Power Research Institute summarises his co-authored paper âActions for reducing US emissions at least 50% by 2030â, the target set by the Biden administration. The paper provides detailed projections and actionable insights about the policies and technology deployment needed to achieve this near-term climate goal. Roughly 70-90% of emissions reductions by 2030 must come from the power and … [Read more...]
If most truck journeys are less than 300 miles the E-Truck revolution can happen now
What proportion of trucks today could go electric? Thatâs the question Emily Porter at RMI has asked for California and New York. The answer is 65% of medium-duty trucks and 49% of heavy-duty trucks. Those are very encouragingly high numbers. RMIâs definition of âelectrifiableâ is if they travel fewer than 300 miles between trips to their home bases. The study gathered real data on how freight trucks are driven today. Clearly, a large number of … [Read more...]
Smart households in a high Renewables world: flexible, efficient, cheaper
Smart controls can enable household heating and EVs to interact flexibly with increasingly decentralised electricity generation. As renewables continue to be added to the energy mix, it will increase efficiency, reduce load, and save money. Marco Reiser and Karoline Steinbacher at Guidehouse summarise the challenges and opportunities, before looking at the SINTEG pilot in Germany. The main hurdles are technological (standardisation, interfaces, … [Read more...]
Using atomic-scale imaging and AI to reduce Battery degradation
Finding ways to extend a batteryâs life starts with understanding why they degrade. Andrew Myers writing for Stanford University describes research there that is using new methods of high-resolution X-ray, electron and neutron microscopy to allow direct visualisation of battery materials at the nanoscale. Degradation is mostly caused by the expansion and contraction of the materials. The high resolution images are processed using AI to uncover … [Read more...]
Critical minerals and materials: supply bottlenecks and risks need international cooperation
The growth in demand for minerals and materials needed for the energy transition is putting a strain on supply. Mining and processing are the two key bottlenecks. Dolf Gielen, Martina Lyons, Francisco Boshell and Peter Chawah at IRENA summarise the multiple challenges. New capacity is not the only problem: the geographical concentration of where the mining and, in particular, the processing is being done is the primary risk. Chinaâs dominance in … [Read more...]
Grid-scale modelling of Distributed Energy Resources and dynamic pricing for all customers
Smart grids can solve multiple problems now and throughout the lifetime of the energy transition. The supply from hundreds (existing + new wind, solar, etc.) and ultimately millions (rooftop solar, EV batteries) of power sources can be matched in real time with demand from all major customer devices (air conditioners, water heaters, batteries, EVs). Dynamic pricing keeps the peaks low and the troughs high. It takes the pressure off total load, … [Read more...]
