The Sustainable Aviation Challenge has identified 16 innovative firms that can accelerate the development and adoption of sustainable aviation fuel and other propulsion solutions. Aviation accounts for 2% of global emissions and, so long as lightweight compact clean aviation fuels are unavailable, this number is likely to increase along with air travel projections. Gianluca Gygax at the World Economic Forum lists the 16 firms, who will now be … [Read more...]
Clean energy forecast map tells firms where to build their facilities to minimise emissions
For companies that are serious about their net-zero targets, where you run a facility affects your results. Building a new facility in a region where renewables are ramping up will keep your emissions low. Connor O'Neil at NREL explains how analysts there, in partnership with Amazon, are building out datasets that take a forward look at where clean energy is growing. The âCambiumâ data sets contain modelled hourly emission, cost, and operational … [Read more...]
China didnât sign the global pledge to triple Renewables and double Efficiency. Why?
Announced at COP28, a total of 123 countries committed to tripling renewable power capacity and doubling energy efficiency by 2030. China didnât. Why? Quoting experts, Lin Zi at China Dialogue explains that the bundling together of the two targets is the problem. Tripling renewables is very achievable; in fact China may well exceed that target. But reducing energy intensity is not easy, even though China has a good record: among the G20 members, … [Read more...]
Global inflation: high borrowing costs threaten the continued growth in Renewables. What must be done?
Over the last decade, investors and governments got used to two supportive trends: relatively cheap capital from low interest rates, and steadily falling costs. However, this changed as the world emerged from the Covid pandemic and into the global energy crisis. In a new era of high interest rates, the impressive growth in renewables deployment is under threat, explain Tim Gould, David Fischer, Paolo Frankl and Heymi Bahar at the IEA. Renewables … [Read more...]
Building and financing the expansion of Europeâs electrical interconnection market
In the first of a series of four articles covering the expanding market for electrical interconnections in Europe, Jean-Baptiste Vaujour at the Emlyon Business School sets the scene by presenting the main points and current developments around the difficulties of building and financing these assets. Interconnectors allow power to be sent across borders to meet the shortfall where supply is not meeting demand. For example, European electricity … [Read more...]
Another good year for Renewables. But can we triple Wind and Solar by 2030?
COP28 saw a calling for a tripling of renewable capacities by 2030, off the back of positive signs. In 2022, 80% of incremental power demand and 12% of electricity generated worldwide came from solar and wind. And the IEA believes solar generation can grow at 25% to 2030. But, as Ramnath Iyer at IEEFA explains, specific challenges must be met to ramp up successfully. The non-financial barriers include a lack of policy clarity, permitting, and … [Read more...]
Four net-zero opportunities for 2024: wind, solar, lab-grown meat, positive tipping points
Will de Freitas at The Conversation draws attention to four reasons to celebrate 2023 and their implications for our drive to tackle climate change. Most will be familiar with the continued progress made with wind and solar, though they deserve repeating given its immense significance. Wind turbines now stand more than a quarter of a kilometre high, and will get taller. At that size, one turn of the blade will power an average home in the … [Read more...]
China is still playing the long game with its ânew threeâ: solar cells, lithium batteries, EVs
Chinaâs ânew threeâ â or xin san yang â are solar cells, lithium-ion batteries, and EVs. The term harks back to the concept of its âold threeâ that were once the pillars of its exports: clothing, home appliances and furniture. Chinaâs success is seen in the numbers: it accounts globally for 80%+ of solar cell exports, 50%+ of lithium-ion batteries and 20%+ of EVs. You Xiaoying, writing for China Dialogue, interviews experts and quotes reports … [Read more...]
EU Energy Outlook to 2060: power prices and revenues predicted for wind, solar, gas, hydrogen + more
Huangluolun Zhou, Elena Dahlem and Alex Schmitt at Energy Brainpool present their updated âEU Energy Outlook 2060â, modelling how the European energy system will undergo major changes in the coming decades while continuing to guarantee a secure supply and meet its climate targets. What do these developments mean for power prices, revenue potential and risks for solar PV and wind? The two main scenarios are âCentralâ and âGoHydrogenâ for the EU 27 … [Read more...]
Improved âSolar Thermochemicalâ process captures 40% of the sunâs heat to produce Green Hydrogen
The U.S. Department of Energy has set a goal to make green hydrogen domestically at $1 per kilogram by 2030. Current costs range from $3 to $8 and none of it is being done at scale. Getting the cost of green hydrogen down is a serious concern for policymakers and industry alike. Most efforts are through electrolysis, which used electricity to split the water that delivers the hydrogen production. Jennifer Chu at MIT describes research there on … [Read more...]
Investing billions in new cross-border Electricity Transmission capacity can cover its costs within a few years
The huge divergence of electricity prices between nations after the energy crises of 2021 and 2022 exposed Europeâs pressing need to increase cross-border transmission capacity, explain George Dimopoulos, Conall Heussaff and Georg Zachmann at Bruegel. Without it, generation costs will be higher, emissions too, and new generation will continue to be badly congested. The authorâs calculations reveal that one additional MW of cross-border capacity … [Read more...]
Clean energy is driving job growth, but skills shortages are a major barrier
The second edition of the IEAâs annual World Energy Employment report measures energy sector employment by region, fuel, technology, and value chain. Globally, energy employment rose to 67m people in 2022. Over half of employment growth since before the pandemic was in just five sectors: solar, wind, EVs, batteries, heat pumps, and critical minerals mining. In fact, clean energy jobs overtook fossil fuels in 2021. But skilled labour shortages are … [Read more...]
New Solar study: 50% of global power by 2050, even without more ambitious climate policies
Nadia Ameli at UCL and Femke Nijsse and Jean-Francois Mercure at the University of Exeter present their study that shows solar is on track to make up more than half of global electricity generation by 2050, even without more ambitious climate policies. This far exceeds any previous estimates: last yearâs IEA World Energy Outlook predicted that solar would account for only 25% by 2050. The authorsâ macroeconomic model takes the latest … [Read more...]
Chinaâs Belt and Road Initiative is now building more Renewables, less Coal
Energy has always made up the majority of investments and construction deals signed through Chinaâs Belt and Road Initiative (BRI). Until very recently these investments were dominated by fossil fuel projects. But in the first half of this year, over 40% of BRI energy projects announced were wind and solar, with 22% each for gas and oil, and zero for coal projects. The reasons include Chinaâs stated commitment to clean energy, avoiding the risk … [Read more...]
China can learn from the EU about power market design and infrastructure build-out
How will China integrate its growing Variable Renewable Energy generation and create a nationwide energy system that avoids the risks of curtailment, stranded assets and blackouts? A good place to start is to learn from Europe. Helen Farrell at ECECP summarises their report that uses the European experience to model scenarios for China. Chinaâs key challenges is that its power market lacks an effective auxiliary service market, a capacity market, … [Read more...]
