The EU ETS carbon price reached a high of over €60 per tonne in September. Some are arguing that its role in the current gas price crisis is a reason why it should be reined in. But Milan Elkerbout at CEPS Policy Insights explains that the EUA (European Union Allowance) has multiple purposes. It is an incentive to invest in low-carbon solutions such as renewables, efficiencies and new methods. The sooner we pass the cost hurdle of integrating … [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...]
Gas crunch: market and policy causes, and lessons learned
Andrei Belyi at the University of Eastern Finland says there are three main causes behind the huge rise in European gas prices. Everyone already understands that the reversal of the previous gas glut that gave us such low prices has been caused by a decline in European gas production, LNG imports and Russian gas deliveries. Added to that is the utilities’ reliance on spot contracts rather than termed contracts – great when prices were low – that … [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...]
How multi-scenario ‘emulator’ models are improving climate change projections
State-of-the-art Earth System Models (ESMs) simulate the flow of energy, moisture and chemicals through the atmosphere, ocean and land surface in unprecedented detail. But the data processing is so demanding that each scenario takes considerable time and expense to run, needing powerful supercomputers and teams of scientists and programmers to produce the models and analyse the results. “Emulators” are much simpler models that can run on a … [Read more...]
DoE study: 45% of U.S. power from Solar by 2050. How?
This month, the White House released a U.S. Department of Energy report, the Solar Futures Study, on how solar power could generate up to 45% of the U.S. electricity supply by 2050. It’s less than 4% today. Joshua Rhodes at the University of Texas at Austin looks at what obstacles must be overcome. The good news is that the technology and engineering is already available. And solar’s advantage is that the sun shines nationwide. Other region and … [Read more...]
Ice for storage for intermittent renewables, then for cooling
Cooling accounts for around a fifth of total energy consumption in buildings. All those air conditioners and electric fans make up a tenth of all global electricity consumption. Demand will keep rising as developing nations get wealthier. Andrea Willige, writing for the World Economic Forum, looks at ice as a seemingly simple solution. Ice can be used as an energy store like a battery, to balance the grid. Create it when energy is cheap (at … [Read more...]
Will Norway’s new government consider phasing out oil and gas?
A Labour-led left coalition won the Norwegian elections in September. The Socialist Left Party looks keen to limit new oil and gas exploration and production. The dominant Labour Party and the Center party, much less so. Still, it could be the moment when Norway starts to put the climate above its oil and gas policy, explains Silje Lundberg at Oil Change International. Until now – left or right - it’s definitely been the other way around. The … [Read more...]
Appliances and Equipment Efficiency Standards: energy savings rival total Wind & Solar generation
Don’t underestimate the effect of Energy Efficiency Standards and Labelling (EES&L) programmes for appliances and equipment, says the IEA. In other words, the gradual tightening of efficiency rules for things like refrigerators, ACs, TVs, washing machines, cookers, vending machines and other electronics. In the nine countries and regions measured (including the U.S., the EU and China), EES&L programmes reduced electricity consumption by … [Read more...]
Energy Efficiency solutions for electrification can help deliver the Transition – with the right policies
The latest climate assessment from the IPCC has underlined the urgency for the energy sector to make the transition quickly and effectively to net zero. The general drive towards mass electrification is a vast and complex undertaking but one that is made more manageable by the innovative development of energy efficient solutions for the built environment. Vesa Laisi, President at Danfoss Drives, outlines how cutting edge technologies are ready to … [Read more...]
The U.S. now needs a Carbon Tax to transition from Gas to Renewables
Gas emissions must be halved (and coal eliminated) by 2030 to meet President Biden’s goal of a carbon free power sector by 2035. The problem is that gas additions are half the price of new wind and solar installations. Though the clean energy champions are still getting cheaper, so are gas additions. Nikos Tsafos at the Center for Strategic and International Studies looks at the policy options over the next decade for the U.S. The stark fact is … [Read more...]
Germany 2021: coal generation is rising, but the switch to gas should continue
As news across Europe shows, a combination of factors is seeing coal powered electricity generation on the increase. Simon Göss at cr.hub, writing for Energy Brainpool, takes a close look at what’s going on in Germany. The post-pandemic demand bounce-back, low generation from wind due to calm weather, and record high gas prices have made coal more competitive. That’s even with rising prices for CO2 and record high prices for coal (caused by … [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...]
Energy-efficient and affordable housing will increase public support for the Green Deal
Energy poverty – the inability to afford basic household energy needs – affects up to one-third of U.S and European households. The energy transition can be part of the solution, says Clare Taylor. Targeted energy-efficient retrofits and newbuilds for low-income households will cut bills and improve living conditions. This will not only cut emissions, but get the beneficiaries behind wider climate change policies like the Green Deals in Europe … [Read more...]
Can full-scale Distributed Solar really save $473bn in grid investments?
A giant model of the entire US electricity sector which captures distributed energy resource (DER) potential has been getting a lot of attention. It estimates that distributed solar and storage can save $473bn in system-wide costs when deployed at scale (enough to power more than 25% of US homes). Rooftop solar is definitely much more expensive than grid generation, but its location (on your own roof) avoids a range of costly transmission and … [Read more...]
