The EU is not on track to meet its Paris Agreement obligations on emissions and limiting the global temperature rise to 1.5°C. CAN Europe and the European Environmental Bureau (EEB) present their Paris Agreement Compatible (PAC) scenario, designed to do just that. It’s been created through the careful analysis of contributions from more than 150 stakeholders including NGOs, scientists, industry and grid operators. Jörg Mühlenhoff at CAN Europe … [Read more...]
Waste Heat Recovery can help replace Poland’s District Heating coal
Three quarters of all district heating in Poland comes from burning coal. So the country is looking for ways to reduce this. It’s why subsidies are provided for combined heat and power (CHP) plants that burn either coal, gas or biomass, which all have lower emissions. But a report by IEEFA authored by Gerard Wynn, Arjun Flora and Paolo Coghe says that waste heat recovery (WHR) – currently unsubsidised – is both emissions free and can be … [Read more...]
Imported U.S. LNG: what’s its true climate footprint?
Importing LNG from the U.S., to replace coal, makes sense for Europe only if the total emissions including those throughout the chain of production are lower than the alternatives. Julian Wettengel at CLEW looks at reports that say the total methane emissions from the world’s largest oil and gas field – the Permian Basin in West Texas – are particularly high and may push it over that threshold. Flaring, venting and leakage are the main cause. … [Read more...]
Developing nations: Efficiency is cheaper than Coal in Indonesia
Developing economies face a particularly big challenge in reducing emissions. Their economies are growing rapidly, industrialising and urbanising. Their populations surely deserve the same rewards of wealth that the rich countries – the historical and per capita big emitters - have experienced. Can they get there without all the emissions? Indonesia believes so, committing itself to 29% unconditional emissions reductions by 2030. Virginie … [Read more...]
Negative electricity prices: lockdown’s demand slump exposes inflexibility of German power
The lockdown has unexpectedly allowed us to model certain aspects of the energy sector’s possible future. One is the oversupply of variable renewables into the grid. In Germany, a slump in demand plus an exceptionally sunny and windy few months sent wholesale electricity prices negative and to record lows. Fossil generators calculated that paying buyers to take electricity was cheaper than performing a shut-down re-start sequence, so they did … [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...]
Coal exit saves money when public health, land degradation costs added – analysis
Coal is cheap. In countries historically reliant on it, as well as emerging economies still building plants, switching to cleaner energy just doesn’t seem to add up. That’s when you’re only looking at your national energy system costs. But the externality costs of air pollution, public health and a degraded local environment are rarely factored in to the equation. When they are, explains Sebastian Rauner writing for Carbon Brief, abandoning coal … [Read more...]
Will China build more Coal to stimulate the economy?
Could China ramp up coal generation – of the order of hundreds of GW by 2030 - as part of its efforts to stimulate its economy and recover from the coronavirus slump? The thinking is that building a coal plant converts faster into economic growth than the equivalent spent on renewables. In the previous decade, building coal plants was an effective part of China’s economic growth plan that secured its place as the world’s second largest economy. … [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...]
Don’t blame Wind, Solar for Coal cycling. It’s everyday variable demand
Joseph Daniel at the Union of Concerned Scientists explains why variable renewables like wind and solar are not forcing coal plants to cycle (ramp up and down). He presents data from the U.S. that clearly shows it’s straightforward variable demand that’s doing it, because demand has always varied considerably throughout the day. So stop blaming the arrival and growth of wind and solar for this “inefficiency”, he says. These renewables have plenty … [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...]
Poland’s PGE: profits from Renewables can replace declining Coal’s
Poland’s PGE is one of Europe’s most fossil fuel intensive energy firms. Coal makes up around 90% of its electricity generation. It’s been investing around PLN 28bn ($7.2bn, €7bn) to build three new coal power plant units, acquire the Polish coal assets of France’s EDF, and upgrade its existing fleet to meet air quality standards. But a new and detailed report from IEEFA warns that the profitability of these investments will decline in the 2020s … [Read more...]
Even cycling Coal is losing money. Only “summer” coal makes sense in Texas, Louisiana
Joseph Daniel at the Union of Concerned Scientists says a detailed look at the U.S. data shows the days of coal plants being the baseload kings are numbered. The declining costs of wind, solar and gas are making coal look expensive. What’s more, increasing energy efficiency is flattening peak demand (and therefore prices), squeezing those periods when coal could rely on finding customers. That means coal plant owners that say they deserve support … [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...]
