The ECâs new series of proposed targets and reforms, contained in its Green Deal Industrial Plan, aim to ensure that at least 40% of the EUâs low-carbon technologies will be made within its borders by 2030. The eight âstrategic net-zero technologiesâ are: Solar (power and thermal); Onshore and offshore wind; Batteries and energy storage; Heat pumps and geothermal; Electrolysers and fuel cells; Sustainable biogas/biomethane; CCS; Grid … [Read more...]
Fulfilling U.S. wind and solar ambitions will use under 1% of its land (thatâs less than the fossil fuel footprint)
Meeting the U.S.âs wind and solar ambitions in full would take up less than 1% of its land, less than the fossil fuel industryâs current footprint. Steve Clemmer at UCS goes into the details of NRELâs comprehensive study of land use for wind and solar. Of particular interest is the observation that setting a high bar for âresponsible sitingâ of wind and solar projects - avoiding the use of sensitive, protected, urban areas, difficult terrain or … [Read more...]
Critical Minerals: will there be enough to meet the 2050 net-zero emissions target?
If the production and processing of critical minerals cannot keep up with the accelerating adoption of batteries, EVs, wind turbines and solar PV technologies, the pace and success of the global energy system transformation will be put at risk. In this explainer, Lilly Yejin Lee and James Glynn at the Center on Global Energy Policy, Columbia University address the big questions, drawing on the data underlying the IEAâs âThe Role of Critical … [Read more...]
EU: data shows RussiaâUkraine war has not increased Coal and emissions. Itâs quite the opposite
The Russian gas crisis has not resulted in the return of coal and high emissions in Europe, says Lauri Myllyvirta at CREA. He presents the figures that show quite the opposite. Coal returned, as expected, with the post-Covid rebound, but peaked in September 2022 below its pre-Covid level, and has been falling since along with emissions. Meanwhile, high gas prices caused by Russiaâs cut-off has kept gas demand low and, more importantly, driven the … [Read more...]
Green Hydrogenâs 6,000-fold scale-up by 2050 must far exceed Wind and Solarâs. Is it possible?
To scale âgreenâ hydrogen to make its contribution to limiting warming to 1.5C, electrolyser capacity needs to grow 6,000-fold by 2050 from todayâs levels of 600MW, according to the IEAâs Net-Zero emissions by 2050 scenario. Adrian Odenweller and Falko Ueckerdt at the Potsdam Institute for Climate Impact Research, writing for Carbon Brief, summarise their study that concludes even if electrolyser capacity grows as quickly as wind and solar, it is … [Read more...]
What if Exxon had acted on its 1970s climate forecast? No climate crisis, cheap energy, Exxon the unrivalled top global energy firm
In January the world media widely covered a paper published in Science that looked at the internal Exxon report that predicted the climate change crisis we now all know we are facing. The paper concludes that the Exxon forecasts were very accurate. John Grant at Sheffield Hallam University composes a counterfactual history of what would have happened in Exxon and the world had taken the report seriously and acted immediately. Yes, weâd have … [Read more...]
Wind and Solar generated record 20% of EU electricity in 2022. More than gas, nuclear, hydro, coal
Now 2022 is over, the figures are in for all the main electricity generation types. For the first time ever, wind and solar delivered more electricity in 2022 than gas, nuclear, hydro or coal. In total, thatâs a record one-fifth of the EUâs electricity last year. We can thank the âtriple crisisâ of Russian gas cuts, the 500-year record droughtâs effect on hydro, and the unexpected French nuclear shutdowns for the renewed drive for wind and solar. … [Read more...]
Wind (and Solar) need their own Financial Transmission Rights to hedge their unique congestion risks
Financial Transmission Rights (FTRs) help generators and load-serving entities hedge congestion-related risk. Transmission congestion causes a divergence between wholesale power prices where it is generated and the trading hubs where it is delivered and sold. Because the congestion, and therefore the risk, varies over time it is particularly important to variable renewables. That uncertainty increases investor risk which potentially slows … [Read more...]
How to tax renewable energy firms for windfall profits from high wholesale electricity prices
Should windfall taxes be imposed on renewable energy firms that have benefitted from the current high electricity prices caused by the increases in oil, gas and coal prices triggered by Russiaâs invasion of Ukraine? If so, how, and how much? The IEA has conducted a study of the EU to try to uncover who has (and hasnât) made extraordinary profits, and how much. Up front they say this is difficult to do as the majority of installed renewable … [Read more...]
Russia, fossil prices, energy security will boost Renewables to 38% of global power mix by 2027, says IEA
The IEA has raised its 2027 forecasts for total renewables additions in its main scenario to 2,383GW â around the total power capacity of China. Thatâs a 28% increase on the previous estimate and up 76% from two years ago, explains Josh Gabbatiss at Carbon Brief who summarises the IEAâs latest forecasts. Globally, solar power will overtake gas by installed capacity in 2026 and coal in 2027. There are two main drivers for this acceleration. High … [Read more...]
Distribution Grid Digitalisation – benefits, policy, cost & funding
About a third of European grids are over 40 years old. A rapid physical overhaul would be impossible, so the addition of a layer of digital technologies is the key to preparing them for the distributed and intermittent generation from renewable sources, the increased electricity demand from transportation, heat pumps and other sectors, and for ensuring energy efficiency at all levels. Itâs why the EC expects about âŹ584bn of investment in Europeâs … [Read more...]
Health benefits of Wind Power: first replace the most polluting fossil plants, not the most expensive
It makes economic sense, when intermittent wind (or solar) generation rises, to turn down the most expensive fossil plants. Or does it? Join the dots to health costs and it may make more economic sense to turn down the most polluting plants first. Jennifer Chu at MIT describes research there that creates models and scenarios to interrogate that theory. Using hourly generation records, pollution and health cost data from across the U.S. they found … [Read more...]
Comparing the efficiency and progress of the 5 leading Solar PV cell technologies
NRELâs âBest Research-Cell Efficiency Chartâ allows researchers to easily compare the performance of specific PV technologies, stretching back 50 years. Itâs regularly updated and is free to use, explains Wayne Hicks and Harrison Dreves at NREL. A new âinteractiveâ version is now available. The focus is on crystalline silicon cells, single-junction gallium arsenide cells, multijunction cells, thin films, and emerging PV. For example, you can … [Read more...]
EU Energy Outlook to 2060: how will power prices and revenues develop for wind, solar, gas, hydrogen + more
Alex Schmitt and Huangluolun Zhou at Energy Brainpool present a summary of their âEU Energy Outlook 2060â. Its scenarios map out how the European (EU 27, UK, Switzerland and Norway) energy system will change dramatically in the coming decades. Current geopolitical tensions are added to climate mitigation and an outdated power plant fleet as the main drivers of change at the EU and national levels. The in-depth modelling is trying to answer the … [Read more...]
Can Enhanced Geothermal Systems be used as grid-scale batteries? Anywhere!
The US Department of Energy aims to cut the cost of Enhanced Geothermal Systems (EGS) by 90% by 2035. Standard geothermal power comes from tapping existing hydrothermal reservoirs. But most places donât have hot water reservoirs underground. EGS pumps water down to reach hot rocks, heating the water to achieve the same purpose. Everywhere has hot rocks underground. Here, Stefan Ellerbeck, writing for the World Economic Forum, describes research … [Read more...]
