Literally anything that moves is using energy that can be harnessed. Not just waves rolling toward shore but cars depressing roads, buildings swaying in the wind, and much more. One way to harness it is to create a material that can be woven into the fabric of roads and buildings so that it captures the energy and converts it into electricity. Caitlin McDermott-Murphy at NREL describes research into Hexagonal Distributed Embedded Energy … [Read more...]
Iron Ore miners try different multi-billion strategies to lower emissions for Steel producers
2024 should see a further acceleration in steel’s transition away from coal, with increasing pressure on companies in the value chain to act on their Scope 3 (indirect) emissions, explains Simon Nicholas at IEEFA. Old coal-fired blast furnaces that use low-grade iron ore are already being replaced with the direct reduced iron (DRI) process in Europe and China. That means the “big four” iron ore miners have to ramp up production of high-grade iron … [Read more...]
The link between global GDP growth and CO2 emissions is weakening rapidly. Will emissions peak well before 2030?
Economic growth has been closely tied to rising greenhouse gas emissions since the industrial age. But data now clearly shows that that GDP growth and CO2 emissions are diverging. Siddharth Singh at the IEA presents the numbers. In advanced economies that divergence now seems locked in, with 2007 marking the moment of peak emissions (and not simply because of offshoring manufacturing). Even in developing economies GDP growth is far outpacing … [Read more...]
Will EU decarbonisation policies shift the Fertiliser industry into making Ammonia for energy (but outside the EU)?
The EU’s fertiliser industry must face up to the region’s ambitious decarbonisation rules, making its carbon-intensive processes much more costly. But a door of opportunity is also being opened: the industry already produces ammonia which is increasingly being seen as an alternative clean fuel, explains Hyung-Ja de Zeeuw at Rabobank. The problem for EU nations is that it will be cheaper for the industry to relocate and make that ammonia somewhere … [Read more...]
Italy: Capacity Auctions for 71 GWh of additional Grid Storage
Italy needs 71 GWh of new utility-scale electricity storage capacity by 2030 to meet EU targets to cut emissions by at least 55% by 2030, according to Terna which manages Italy’s transmission grid. ***STOP PRESS*** This Tuesday at 11:00 CET, Energy Post is exclusive media partner to a dedicated webinar (organised by ATA Insights/RENMAD) on Capacity Market Auctions REGISTER FREE HERE. In this article, Sara Stefanini summarises the Terna study, … [Read more...]
District Heating: Molten Salt boilers beat Water for storing intermittent Wind & Solar power
District heating networks, an important part of the energy transition for buildings, need a way of storing intermittent wind and solar power. But water tanks have limits: they take up a lot of space, and have a low thermal energy storage density (limited by the 100°C boiling point). Molten salts have a much higher storage density (regular table salt has a melting point of 801°C), but a melting point that is too high is not safe where ordinary … [Read more...]
Geothermal Heat Pumps at scale avoid the cost of expensive long-distance transmission lines
A new analysis reveals that installing geothermal heat pumps in 70% of U.S. buildings can reduce the need for new long-distance transmission lines by 33%, explains Kelly MacGregor at NREL. The main message is that, though geothermal deployment is seen as expensive, the avoided costs are significant. Those transmission lines won’t be needed because geothermal is always local and can be deployed in both urban and rural places. Though the widespread … [Read more...]
Is global energy security being used as an excuse to build more U.S. LNG export capacity?
Europe’s energy security is being used as an excuse in the U.S. to build more LNG terminals than are actually needed, argues Ana Maria Jaller-Makarewicz at IEEFA. European gas demand is expected to keep falling. Even with U.S. projects that are currently under construction, its LNG export capacity in 2030 will be 76% higher than Europe’s forecast demand. The U.S. should seriously re-evaluate its strategy or risk overinvestment, says … [Read more...]
What’s Plaguing Voluntary Carbon Markets?
In voluntary carbon markets, buyers (like big companies with emissions) voluntarily purchase and trade in offsets generated from emissions reduction or removal projects elsewhere. And in early 2023 momentum was building for them, but that soon collapsed as evidence of greenwashing grew: forestry programs were significantly overestimating their value. Allegra Dawes at CSIS lays out the background before explaining that systems must be put in place … [Read more...]
Just Transition: UK’s Port Talbot steelworks are closing. What can be learnt from the Netherlands and Sweden?
A classic “just transition” story is being played out in the UK, a high income nation and Europe’s second biggest economy. Tata Steel plans to cut almost 3,000 jobs at the UK’s largest steelworks. The location, Port Talbot, is one of the most deprived places in the UK and the steelworks there are its largest private sector employer. Tata is under pressure to decarbonise its steel production, so will switch to an electric arc furnace that recycles … [Read more...]
Biogas from dairy farms: what incentives can make it commercially viable?
Anaerobic digesters are used to turn cow manure into useable methane fuel. But the raw cost of that gas is ten times the market price. On the plus side, emissions are being avoided. So how do you create the incentives that are fair and make it commercially viable? In California, dairy biogas has risen from almost non-existence five years ago to delivering half of all natural gas used for transportation in the state. Aaron Smith at the Energy … [Read more...]
Tandem solar cells (perovskite + silicon) can reach 40% energy conversion rates
Tandem solar lays new perovskite cells over standard silicon cells. Perovskite absorbs the shorter wavelengths of light that silicon misses. So the thin layer of perovskite collects the visible wavelengths, and lets the near-infrared light through to the silicon underneath. Martina GrĂĽnwald and Sarah Michaud writing for the WEF point at the results of R&D and demonstrations in Germany, Switzerland, Saudi Arabia and China. Energy conversion … [Read more...]
EU’s fossil fuel CO2 emissions drop to levels last seen in the 1960s
The EU’s CO2 emissions from fossil fuels (including power generation, industry and transport) dropped 8% in 2023 year-on-year, reaching levels last seen in the early 1960s, reveals an analysis by CREA. More than half of that decline came from an impressive 25% year-on-year reduction in CO2 emissions from power generation. The cleaner electricity mix is thanks to the continuous rise of wind and solar as well as a rebound in hydropower and nuclear. … [Read more...]
EU ETS or national climate targets? We need both
The choice between using the EU ETS or national climate targets to decarbonise is a false dilemma. We need both, explains Chiara Corradi at T&E writing for the Florence School of Regulation. There are plenty of examples where a carbon market and national targets have delivered good results together, as in Germany, Finland, Denmark and Portugal. And, looking ahead over the next few decades, the right policies should be able to cope with ETS … [Read more...]
U.S. and EU: vastly different approaches to trade and climate put a transatlantic deal at risk
Uncertainty over the results of this year’s elections in the U.S. and the EU have effectively postponed trade deals between the two blocks. That means when talks restart in 2025 there will be even less time to find the best compromises. As Gautam Jain, Noah Kaufman, Chris Bataille and Sagatom Saha at the Center on Global Energy Policy explain, it’s why this time should be taken to better understand the differences and lay out the possible … [Read more...]
