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, that’s a record one-fifth of the EU’s electricity last year. We can thank the “triple crisis” of Russian gas cuts, the 500-year record drought’s effect on hydro, and the unexpected French nuclear shutdowns for the renewed drive for wind and solar. … [Read more...]
Steel decarbonisation: Australia must stop making excuses and follow Europe’s lead
Australian steel makers, major global exporters, must stop making excuses about decarbonisation and look to Europe for a role model, argues Simon Nicholas at IEEFA. A pattern of behaviour by Australia’s steel makers reveals that their excuse is that low-carbon solutions are not yet ready, leaving only promises of carbon capture (as yet unproven at scale) some time in the future. Nicholas notes that these promises will never have to be kept by the … [Read more...]
Can new cheap, frequent “laser” monitoring of critical components extend Nuclear plant lifetimes by decades?
For nuclear to thrive, rather than retreat and be displaced by alternatives, plants reaching the end of their lifetimes need to be replaced with new ones. Or, perhaps more interestingly, can the existing plants have their lifetimes greatly extended, safely and cheaply? David Chandler at MIT describes new research led by MIT to detect and measure defects in critical components to ensure that damage from heat and radiation has not led, and will not … [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...]
The U.S. should support the EU’s Carbon Border Adjustment Mechanism (CBAM)
The U.S. should get behind Europe’s Carbon Border Adjustment Mechanism (CBAM), says Joseph Majkut at the Center for Strategic and International Studies. Under the EU’s newest agreement, anyone importing CBAM-listed goods into Europe will have to report the emissions associated with their products starting in October, and ultimately face tariffs if those emissions exceed those of the equivalent products made in the EU. The current list is iron and … [Read more...]
Utah: 140MW Geothermal bid can beat the cost and performance of the proposed Nuclear SMR
The U.S. state of Utah is processing an agreement for a new Small Modular Reactor (SMR) to provide baseline and dispatchable power. The SMR bid quotes a price of $89/MWh. But cost overruns will tie the state’s consumers to whatever high prices entail, says Dennis Wamsted at IEEFA. Now a geothermal bid from NV Energy has been presented that offers the same capacity at around $70/MWh. Wamsted explains why the 140MW geothermal project would meet … [Read more...]
Make Hydrogen in developing nations: share prosperity while meeting our climate goals
The new hydrogen economy will not just be global, it must be used as a major economic development opportunity for low income nations and promoting shared prosperity, explain Dolf Gielen, Silvia Carolina Lopez Rocha and Priyank Lathwal at the World Bank. They carefully lay out the obstacles and pathways for making hydrogen in developing countries. It’s very capital intensive, but such projects – think of existing fossil fuels, mining, etc. – have … [Read more...]
Smart Glasses: experts can monitor and advise on power plant inspections anywhere in the world
The pandemic made on-site testing of power stations and their components more complicated – and considerably so in some cases. But it also made a wide range of product and services companies aware of the availability of technology to monitor, manage and repair units remotely. Rather than fly several experts to a single site, the experts can stay where they are and watch the inspection happen virtually, while giving advice and instructions on the … [Read more...]
Concrete: 8% of global emissions and rising. Which innovations can achieve net zero by 2050?
Concrete manufacture is responsible for 8% of global carbon emissions, with the ingredient “clinker” accounting for most of it. Global demand for cement (which hardens into concrete) is expected to increase 48% from 4.2bn to 6.2bn tons by 2050, mainly driven by developing nations. China used more concrete between 2011 and 2013 than the United States did in the entire 20th century. Ben Skinner and Radhika Lalit at RMI look at the materials and … [Read more...]
Biofuel is approaching a feedstock crunch. How bad? And what must be done?
The IEA is warning that biodiesel, renewable diesel and biojet fuel producers are heading for a feedstock supply crunch over the next five years. Rising prices are the signal to seek out new supplies and solutions, which should – and are - driving the development of government programmes and industry innovation. Here, the IEA lays out their projections for 2022-2027, covering all the main feedstocks: sugars, maize, soy oil, rapeseed oil, palm … [Read more...]
Europe needs a Regional Green Bank to fulfil its Green Deal and match the U.S.
Three years in, the European Green Deal remains unfulfilled as a long-term vision for decarbonising Europe by 2050, says Esmeralda Colombo at EIEE. To inject new momentum, in this week’s speech at the World Economic Forum in Davos, EC President Ursula von der Leyen sketched out a Green Deal Industrial Plan to subsidise the cleantech industry and compete with the rest of the world, notably the US, and the EU Sovereignty Fund to equalise the … [Read more...]
How to sell Heat Pumps to the public in Europe
In EU households, 62.8% of energy consumption is for space heating, and another 15.1% for water heating, mostly powered by fossil fuels. Heating and cooling is responsible for 52% of final energy demand in Europe. So, with REPowerEU, the EU has once again strengthened support for heat pumps to achieve energy independence and climate goals. Heat pump sales in Europe grew by an unprecedented 34% in 2021, thanks to a total 2.18m heat pump units … [Read more...]
What’s stopping even bigger Wind Turbines? Blade speed and flexing? More likely manufacturing and installation capacity
Bigger wind turbines make cheaper energy. The sector’s unexpectedly rapid successes in designing and building bigger and bigger turbines has been one of the major success stories of the clean energy sector. In 2023, the biggest turbines in the world will start generating electricity off the coast of the UK. Each of General Electric’s Haliade X turbines stands 260m high from sea level and can generate 13MW at under ÂŁ50/MWh (€56/$61). But how big … [Read more...]
Making Hydrogen will consume 2% of total global renewable capacity growth by 2027
25 countries plus the EU have announced big ambitions for renewable hydrogen production. But how much renewable energy will be needed to make the H2 over the next five years? Nations are not keen to expend new clean energy generation on (expensive today) hydrogen production when their grids are still not emissions-free. According to the IEA, for 2022-2027, their main case forecasts around 50GW of renewable capacity will be dedicated to hydrogen … [Read more...]
EU ETS and CBAM: what the big update to emissions trading rules means for Europe’s key sectors
The EU’s Emissions Trading Scheme is a vital part of the region’s decarbonisation plans. Simon Göss at carboneer digs into the new rules coming in for the existing EU ETS, and the implementation of the new carbon border adjustment mechanism (CBAM). Right now, the existing EU ETS covers around 40% of the EU’s emissions (energy sector, industrial installations and aviation). Its scope is being extended to include maritime transport. On top of that, … [Read more...]
