In long logistical chains (found in steel, concrete, aviation, shipping and others) end consumers that want to pay a premium to cut their emissions (for example to comply with corporate decarbonisation promises) often have no way to pay the first link in that chain to go low-carbon. “Book and Claim” creates a market to do that. Consumers buy certificates, and producers get the money to fulfil the commitment. And a working system will bring to … [Read more...]
Germany to ramp up the decarbonisation of Buildings Heating from Jan 1st 2024. How?
Decarbonising heating is a major challenge for any country. Germany’s Building Energy Act (GEG) means that from 2024 every newly installed heating system, in new or existing buildings, must operate with a minimum of 65% renewable energy. Concerns over the costs to customers (installing new and expensive systems, or paying a penalty for fossil heating) has led to intense debates, hence the new law includes a range of subsidies, bonuses, discounted … [Read more...]
Only certain types of Hybridisation (Wind or Solar + Storage) beat building expensive transmission lines
In some regions, the roll out of new wind and solar has outpaced new transmission. That causes “congestion” at times when the variable renewables are producing too much power locally, and cannot sell the excess, which squeezes profitability. That’s certainly the case in the U.S. now. One answer is “hybridisation” where storage is built alongside the renewables, to save that excess power for when it can be sold later. Julie Mulvaney Kemp at … [Read more...]
France plans the social leasing of EVs at €100/month. Can it jump start affordable electric cars?
Social leasing of EVs could become the breakthrough example of climate action done right, explains William Todts at T&E. And France’s president Macron has promised to do it, aimed at low-income households to counter criticism that even with subsidies EVs are still out of reach for many. Todts quotes T&E analysis that shows that between 2024 and 2030 around 900,000 low-income households could benefit from monthly leasing costs of €70 to … [Read more...]
Nuclear power capacity is growing globally. Where, how and why
Ewan Thomson at the World Economic Forum summarises the state of nuclear power worldwide. In 2020 it made up 10% of global electricity generation, more than all the wind and solar PV combined. It’s the second-largest source of low-emissions electricity. But many advanced countries are no longer backing nuclear, citing safety and cost concerns, and instead are pushing the growing number of alternative clean energy technologies. Nevertheless, … [Read more...]
Building Materials “Embodied Carbon”: reaching net-zero with low-carbon cement, timber, modular design and more
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...]
