Simon Evans at Carbon Brief summarises BP’s 69th edition of its influential annual statistical review of world energy, looking at 2019. Overall, total energy demand rose, though slower than usual. Renewables were the largest source of new energy, but were closely followed by oil and gas. Coal use dropped again, the fourth drop in six years, thanks to historic declines in the EU and the US. But continued growth in SE Asia, China and India leaves … [Read more...]
Russia and U.S. are backing next generation Nuclear
Russia’s Rosatom is positioning itself to lead research and testing for Generation IV fast neutron reactors, including high temperature gas-cooled, molten salt, and lead-bismuth designs. Following an update of plans released by Rosatom in June, Dan Yurman fills in the details. It is creating an International Research Centre and has signed up four partnering nations so far – the Czech Republic, Hungary, Poland, and Slovakia. The R&D facility … [Read more...]
Nuclear: can Silicon Carbide fuel rod cladding improve safety, performance?
Public concern about the safety of nuclear plants is driving research into ways to make the fuel rods more able to survive the kind of unexpected calamity experienced in Fukushima in 2011. Following the tsunami, hydrogen explosions were caused by the conventional zirconium-based fuel cladding interacting with the high temperature steam produced when the safety system failed and coolant water heated up. Writing for MIT, Leda Zimmerman describes … [Read more...]
Investing for tomorrow, because Energy subsidies will decline 25% by 2050 – analysis
IRENA has modelled energy subsidies to 2030 and 2050 for their pathway to meet the Paris targets. Here, Michael Taylor summarises their findings. Firstly, they estimate today’s global direct energy sector subsidies to be $634bn/year (2017 figures). The vast majority, $447bn, went to fossil fuels. (By the way, he points out that none of these figures include the externality costs - pollution, healthcare, environment - which equate to trillions and … [Read more...]
IEA projections 2020: energy demand plunges but Renewables still grow at Gas, Coal’s expense
The IEA has made its projections for the impact of the pandemic lockdown on energy demand in 2020 (they say it’s too early for them to assess anything more long term), and its implications for the different generation types. This article summarises their special Global Energy Review 2020, published at the end of last week. It assumes that lockdowns are eased this year and growth gradually returns. With that, global energy demand will fall 6% in … [Read more...]
Nuclear fusion: public-private pitch for pilot power plant in U.S.
A working nuclear fusion plant has long been a dream of scientists. The “Sun in a box” would generate abundant low carbon energy with little waste and more safely than traditional existing nuclear (fission) plants. But the scientific, engineering and materials challenges are admittedly enormous. Meanwhile, other electricity generating technologies are getting cheaper, so will we ever need it? Nevertheless, a public-private collaboration in the … [Read more...]
AI software to improve Nuclear reactor designs, performance, safety, lifetimes
Nuclear plants have high up-front costs, complex processes occurring all the way down to the molecular level throughout their decades-long lifetimes, and strict safety criteria. Modelling all the parameters and predicting the outcomes has traditionally begun with theory and observation followed by simulations, the results of which are fed back into the next round of theories, and repeated until those results look valid. The quality of the … [Read more...]
China’s 2019 electricity generation reviewed as its next 5-year plan is drafted
Simon Göss breaks down the totals and additions for electricity generation in China. In 2019 the total reached 7,325 TWh (more than twice Europe’s) after adding 330 TWh (more than half Germany’s total). Of that 330 TWh, 120 TWh came from thermal (90%+ coal). But the numbers were dominated by renewables (hydro, wind, solar) which added almost 160 TWh. Though that’s the third year of declining renewables additions, wind and solar curtailment is … [Read more...]
Methane emissions underestimated by 25-40%, says new study
The methane in our atmosphere comes from natural biogenic (plants, animals) and fossil sources. By telling the difference we can know how much we humans are responsible for. It matters because methane is a potent greenhouse gas, second only to CO2. Previous “bottom-up” estimates came from multiplying the number of sources (livestock, natural gas operations, landfills) by their likely emissions. Robert McSweeney at Carbon Brief describes a new … [Read more...]
What if Germany wasn’t shutting down Nuclear? Modelling Coal, Gas, Renewables, emissions, prices
Germany plans to shut down its entire nuclear fleet by 2022. Right now, of the original 17, only 7 are still running. The Fukushima nuclear accident in Japan of 2011 was the trigger for Germany’s abandonment of emissions-free nuclear as part of its clean energy goals. Maximilian Auffhammer at the Energy Institute at Haas reviews a paper by his colleagues that has modelled the whole-system effects of the shutdowns, then compared the results with a … [Read more...]
Defining green investments, ending greenwash: the EU’s new Taxonomy Regulation
When the EU Commission’s new Taxonomy Regulation is approved, expected in March, it will provide the legal framework to define what is a truly ‘green’ investment. As Luca Bonaccorsi at Transport & Environment explains, right now asset managers and national authorities are free to define what is green, allowing some to greenwash investments in things like oil and pesticides. The Taxonomy's purpose is to reduce ambiguity and therefore increase … [Read more...]
200 – 400 Nuclear reactors to be decommissioned by 2040
Denis Iurchak has taken a close look at nuclear decommissioning. Globally, 447 nuclear reactors are in operation as of January 2020. Of those, nearly 70% are older than 30 years (25% are older than 40 years). The IEA says around 200 commercial reactors are to be shut down in the next two decades. On top of that, 182 reactors are already in permanent shutdown. This means that between 200 and 400 reactors are likely to be decommissioned by 2040, … [Read more...]
Gas Switching Reforming: making Hydrogen to balance variable Wind, Solar
What is the best technology to balance the variable output of wind and solar? When there is little wind and sun the plant must produce power to compensate. When there’s too much wind and sun it must utilise that excess power. In other words, given the high capital cost of the new balancing technology it must do both profitably enough to cover the time sitting idle. A paper co-authored by Schalk Cloete looks at Gas Switching Reforming (GSR). The … [Read more...]
The EU can support Central and East Europe’s transition
Six Central and East European nations, heavily dependent on coal, have been very cautious about the pace of the EU’s transition. For them - Bulgaria, Czechia, Hungary, Poland, Romania and Slovakia - the political and economic disruption looks far harder to bear. E3G has just released a report that suggests this picture can change. The report’s authors – Felix Heilmann, Rebekka Popp and Ada Ámon – explain that coal is becoming less profitable, … [Read more...]
U.S. EIA predicts Renewables will surpass Coal by 2021
Renewable electricity generation in the U.S. has risen so fast in the last 10 years that it’s expected to surpass coal by 2021, according to the latest report from the nation’s Energy Information Administration (EIA). This would have been “unthinkable” in 2010, says Dennis Wamsted at IEEFA. Back then, nationwide, utility-scale solar generated 1.29bn kWh and wind 94.6bn kWh. By 2021 solar will have risen almost a hundredfold to 122bn kWh and wind … [Read more...]
