In this explainer Madeline Weir, Audrey Rempher and Rebecca Esau at RMI first describe how embodied carbon is calculated. They then summarise the strategies being employed to reduce it, including using low-carbon, carbon-neutral, or even carbon-storing materials. New cement formulations are being developed with over 60% less CO2 emissions than the regular kind. Low-carbon mass timber is an alternative building material under development. On the … [Read more...]
Carbon Capture rates of 60% sound impressive. But rising carbon prices could still make you commercially unviable
Mainstream scenarios state the unavoidable need for continued use of fossils through to 2050. For the world to stay within its carbon budget, that means the unavoidable need for carbon capture and plugging “fugitive” leaks. Chris Bataille at the Center on Global Energy Policy flags up the danger that new CCS projects with seemingly impressive capture rates of up to 60% may nevertheless become commercially unviable as carbon prices rise: that … [Read more...]
Russia’s war has exposed France and Germany’s energy policy differences. Can it also bring them together?
France and Germany combined account for 45% of EU GDP and 40% of energy consumption. No wonder they are the most influential EU members. But the Russia-induced energy crisis has forced both Paris and Berlin to expose and admit the differences in their national energy strategies, and that has made a search for a unified voice for Europe’s ambitious climate targets much harder to achieve, explain Camille Lafrance and Benjamin Wehrmann at CLEW. … [Read more...]
Russia’s oil export revenue rebounded in March–April. Why aren’t the EU, U.S. and partners enforcing the price cap?
The Price Cap Coalition (PCC) - composed of Australia, Canada, the EU, Japan, the UK, and the U.S. – are failing to either enforce or lower the cap on Russian oil exports as promised, says a report summarised here from the Centre for Research in Energy and Clean Air (CREA). Had it done so, Russian revenues could have been slashed by €22bn (37%) since December by lowering the price cap for crude oil to $30/barrel and revising the caps for oil … [Read more...]
Clean Energy Innovation: investment continued to rise despite a turbulent 2022
In a turbulent year, financially and geopolitically, investment in energy innovation still rose. Public spending on energy R&D grew by 10% in 2022 (estimated at $44bn), with 80% devoted to clean energy. Listed energy-related companies saw a similar rise. And early-stage venture capital investment reached a new high of $6.7bn. But risks remain, explains Simon Bennett at the IEA who summarises the innovation chapter in their latest “World … [Read more...]
Hydropower’s full potential: emulator optimises designs and operations in real time
Hydropower plants are big and expensive. And no two plants are the same, located in different geographies. That makes it very hard to customise and test their design. Contrast that with other clean energy technologies like wind and solar, which are much easier to model, perfect, modularise and then deploy. As Caitlin McDermott-Murphy at NREL explains, it’s why researchers there are creating a hydropower plant emulator that tests designs and how … [Read more...]
Will U.S. become the Global Gas Market’s source of flexibility and security of supply?
The U.S. will take the lead in offering flexibility and security of supply to the global gas market, and at prices linked to its wholesale gas market, the most liquid in the world, argue Kong Chyong and Ira Joseph at the Center on Global Energy Policy. It’s because the U.S. leads in the three key sources of gas trade flexibility, critical to meeting unexpected supply and demand gaps: natural gas storage systems, spare capacity in production and … [Read more...]
Long-duration storage: mechanical, electrochemical, thermal. We’ll need all three
“Long-duration” means the amount of time a power system can discharge electricity (this is different from long-term storage, i.e. the amount of time a system can store energy before discharging it). As Maria Chavez at UCS explains, it’s vital to the success of intermittent wind and solar roll-out which needs to store its excess generation for when it’s needed. And as electrification grows it will provide greater grid flexibility and resilience … [Read more...]
Can the U.S. export its Nuclear plants to Europe, starting with Poland?
The exclusion of Russia from Europe’s energy future opens a door for the U.S. to export its nuclear plants, explain Matt Bowen and Sagatom Saha at the Center on Global Energy Policy. That’s why, in April, the U.S. announced financing of up to $4bn to deploy U.S. small modular reactors (SMRs) in Poland. A successful deployment there could lead to the same in Romania, Slovakia, Estonia, the Czech Republic and Ukraine, all of which have coal plants … [Read more...]
Farming Algae for Carbon Capture: new research cuts “fouling.” Scale-up in 3 years?
Natural marine algae already account for 50% of global CO2 removal. Farming it at scale in artificial tanks or tubes would take up a fraction of the land footprint of terrestrial plants. And algae can grow up to 50 times more quickly than land-based plants. It could be a game-changer that brings carbon capture costs down and make it a commercial reality. Here, David Chandler at MIT explains how new research there can make farming algae much more … [Read more...]
Buildings Efficiency: cars have an “eco mode” button. Why not our homes?
Households need the right tools to be able to take control of their real-time energy consumption, says Maximilian Auffhammer at the Energy Institute at Haas. Smart meters are just too crude. They don’t tell you how much energy individual devices are using – fridges, ovens, heaters, EV chargers, TVs, lightbulbs, toasters, etc. You have to work it out yourself by switching devices on and off and seeing the difference. Auffhammer argues if you price … [Read more...]
Evidence of a direct link between Wildfires and Fossil Fuel firms. Can it be used to sue them?
Wildfires are back in the news. The link to rising global temperatures caused by climate change is clear. Mark Specht at the Union of Concerned Scientists summarises their study that, for the first time, puts a number on the level of responsibility attributable to fossil fuel companies. Rising temperatures create a “vapour pressure deficit,” a measure of the power of the air to dry out plants and trees. That leads to an increase in the area … [Read more...]
Lookahead to 2024 27-nation EU Parliamentary elections: will ambitious climate policies win or lose votes?
In June next year Europeans from 27 nations will elect a new EU Parliament that will shape the bloc’s energy and climate policy in the years leading to the 2030 climate target deadline. It’s not clear whether rising prices, energy security and heatwaves will steer votes towards parties pushing for more rapid decarbonisation, or whether the cost and disruption of transition will do the exact opposite. At the last election in 2019 climate concerns … [Read more...]
Power to the people: citizen-centred Just Transitions challenge energy system centralisation
EU Member States need to phase-out coal and transform their carbon-intensive industries to make Europe climate-neutral. However, these should not be the only goals: transparency and justice must also accompany this path, argue Diana SĂĽsser at IEECP, Serafeim Michas at TEESlab and Ricardo Antonio GarcĂa Mira at the University of A Coruna. As Member States implement their territorial just transition plans, they must ensure they benefit affected … [Read more...]
Ammonia from water microdroplets: lab demonstrates cheap, low-tech production
Very early stage research has discovered a new way of making ammonia cheaply, on a small scale (or large, if you want!), and with no harmful emissions, explains Adam Hadhazy writing for Stanford University. The process uses a cocktail of water, nitrogen gas, and a solid catalyst sprayed through a simple, low-tech instrument to make the ammonia. In contrast, the existing industry-standard Haber-Bosch process is energy intensive, large scale, and … [Read more...]
