For the system of Nationally Determined Contributions (NDCs) to be effective, every country’s reporting processes need to be appropriate to their economic level, honest and accurate. That means the Paris Agreement’s Transparency Framework, including the Common Reporting Tables (CRT) for greenhouse gas inventories, and Common Tabular Formats (CTF) to track progress on their NDCs, needs to be finalised and agreed upon, and fast, says the IDDRI’s … [Read more...]
Wind power predictions doubled by factoring in far-future design improvements
Existing studies estimate all Europe’s potential total maximum annual generation from wind is between 16 and 21 petawatt hours (PWh), already over five times Europe’s existing electricity total from all sources (3.6PWh). A new study doubles that figure to 34.3PWh. The study claims to improve on the accuracy of two factors used in making these predictions, explains Josh Gabbatiss at Carbon Brief. Firstly, it uses what it believes are realistic … [Read more...]
EU ETS Modernisation Fund: putting the wind in the sails of the Transition
Transforming the power system to reach climate neutrality by 2050 will cost approximately €100bn per year according to Eurelectric. In recognition of the different starting points for Member States, the European Commission has introduced the new EU ETS Modernisation Fund (MF) which could be worth as much as €25bn* to the beneficiaries between 2021 and 2030. According to Monika Morawiecka, CEO of PGE Baltica, offshore wind already makes business … [Read more...]
New solar cell allows a photon to release two electrons, not just one
In conventional silicon-based solar cells, each photon of light can only knock loose a single electron, creating electricity. That’s even if the photon carries more than enough energy to do so. One hammer, one nail. Now, for the first time researchers at MIT and Princeton University in the U.S. have got high-energy photons to strike silicon and kick out two electrons instead of one, opening the door for a new kind of solar cell with greater … [Read more...]
Cheaper than coal: IRENA’s comprehensive report on cost declines, all renewables categories
The International Renewable Energy Agency’s (IRENA) latest report Renewable Power Generation Costs in 2018 details the global weighted-average levelised cost of electricity (LCOE) for all commercially available renewable technologies. It states that renewables are already the lowest-cost source of new power generation in many parts of the world today. By as soon as 2020, onshore wind and solar PV will join hydropower in consistently offering a … [Read more...]
Is selling nuclear plants for decommissioning a safety issue?
In the U.S., last month, the $48bn nuclear firm Exelon sold its Oyster Creek power plant to a smaller privately-owned firm, Holtec International, that specialises in decommissioning. It’s one of several similar recent transactions that sound sensible. But Lucas Davis, at the Haas School of Business, and Catherine Hausman, of the University of Michigan, argue this may present an economic text book case of “moral hazard”. Big firms are more likely … [Read more...]
China’s coal needs Carbon Capture. Can U.S. knowledge help?
To limit global warming to 1.5°C, carbon capture and storage (CCS) plays a crucial role. We still live in a world where coal (mainly in developing countries) and gas (almost everywhere) continues to power growing economies. But the pipeline of new large-scale CCS facilities is nowhere close to what we need: around a hundred new units every year between 2020 and 2040, according to the Global CCS Institute. A report by the IFRI Centre for Energy … [Read more...]
OPEC is driving itself to irrelevance with farcical aplomb
It took months of delays but even before the cartel’s latest ministers meeting began in Vienna, the Saudis and Russians rendered it meaningless by largely deciding an outcome that failed to surprise the market. Not that long ago, a meeting of the Organization of Petroleum Exporting Countries (OPEC) carried great weight in the global energy market and was accompanied by intense anticipation. The powerful oil producer’s cartel at one point held … [Read more...]
Grid-scale batteries: further price drops result in concrete investments
With so much focus on renewable gas and heat as a means of offering dispatchable power it was interesting to note ScottishPower’s announcement of a new, gigantic battery storage facility. Lest we forget, battery energy storage is one of the fastest-growing sectors in the clean energy field and it is scaling up at an astonishing rate, not just in terms of overall capacity but also in terms of the size of individual projects, as the extent of the … [Read more...]
Investing in renewables in China: relatively good times
With the Chinese state increasingly confident of its renewable energy technologies and manufacturing, European firms are finding conditions right to invest in the sector there. Joe Mitton looks at the conditions for investors, and why EU-Chinese energy partnerships must not be caught up in the US trade war. Energy Post’s Matthew James spoke to Sebastian Meyer, Vice President at EDF Renewables, about his experiences. To read FULL ARTICLE login … [Read more...]
Wind Farm “wake steering”: small re-alignments of turbines can increase output by 40%
The wake from one wind turbine makes the turbines behind it less efficient. It’s similar to the way a speedboat is slowed by the choppy water caused by the boat in front. Vincent Xia reports on how scientists at Stanford University have been testing ways of fine-tuning the alignment of turbine arrays to reduce turbulence and increase output. The biggest wins (a 47% increase) are at low wind speeds, when turbines can otherwise stop altogether. At … [Read more...]
Developing world urbanisation: a great opportunity for smartgrids, buildings efficiency
Rapid urbanisation in the developing world means millions of new buildings are going up. Now is the time to make sure they are energy efficient from the start, avoiding the major “rich world” headache of retrofitting. Given most of the developing world exists in hotter climates, cooling – unchecked - could account for as much as 40% of final electricity demand in some countries by 2050. To keep a cap on that, efficient buildings and air … [Read more...]
Kenya, Bangladesh: Environmental rulings stall coal plans. So should the economics
The construction of two coal-fired power plants has been stalled in Kenya by the Kenyan courts and in Bangladesh by UNESCO, both for environmental reasons. It’s an opportunity for the two countries to also recognise the purely commercial reasons to go for renewables, says Simon Nicholas of IEEFA. While most of Asia has been powering ahead with renewables, Bangladesh has been lagging behind. But a continued rollout of renewable energy will quickly … [Read more...]
A cheap Carbon Capture breakthrough? MOF molecular cages that trap CO2
Carbon Capture is the Transition’s great unknown. Big targets have been set but nobody knows how we’re going to meet them. It's clear we need utility-scale breakthroughs, and fast. And cheap. We take a look at one example of cutting edge research that could deliver both. Scientists at the U.S. Department of Energy’s SLAC Laboratory and Stanford University have taken the first images of CO2 molecules captured within a highly porous nanoparticle … [Read more...]
Gas v Electric new buildings: U.S. standards agency backs gas with out-of-date data, says RMI
Official reports matter. That’s why the Rocky Mountain Institute (RMI) is taking to task the U.S.’s National Institute for Standards and Technology (NIST) which published a paper stating that all-electric systems are more carbon intensive and more costly than gas-fired systems in new buildings. The NIST paper assumed a high reliance on coal as the primary source for electricity generation in their Maryland case study. Those stats are out of date, … [Read more...]
