Though the UK is a leader in grid electrification it is a poor performer when it comes to the electrification of heating. In May the UK government proposed a clean heat policy to support the switch away from gas heating for 12,500 homes a year for two years. Jan Rosenow and Samuel Thomas at RAP say that looks like business as usual: for every one new low-carbon heating system, more than 120 gas boilers will be installed as normal. In 2019, 1.7m … [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...]
Sales down, but cash preserved too: Regulators take note when setting new Utility rates
Utilities are suffering financial impacts because of the current pandemic, and regulators will be asked to address them when they set new electricity rates. The intention will be to help the utilities recover while keeping bills affordable for their customers. But not all the impacts on the utilities are bad news, explains Jim Lazar at RAP looking at the U.S. Though revenues have dropped and some labour costs risen, there is a list of things that … [Read more...]
Allam Cycle carbon capture gas plants: 11% more efficient, all CO2 captured
Globally, carbon capture is making precious little progress. Is the Allam Cycle natural gas power plant an important step forward? David Yellen at the Atlantic Council Global Energy Center explains that, according to its designers, its energy conversion efficiency is 59%, 11% more than a standard combined-cycle gas turbine plant that’s carbon capture-equipped. It also captures 100% of the CO2, 10% more than the standard. NET Power plans to bring … [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...]
An EU Hydrogen strategy: from industry feedstock to energy vector
The bravest recovery strategies will invest robustly in new yet-to-take-off clean energy technologies. If you are going to have to spend hundreds of billions to revive your economy isn’t it better to replace the old with the new rather than prop up what you’ll have to abandon soon anyway? In anticipation of that happening, new technologies are lining up. Here, CĂ©dric Philibert at the IFRI Centre for Energy & Climate summarises their detailed … [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...]
Bounceback or Recession? Modelling the impact on electricity prices to 2025
Carlos Perez Linkenheil at Energy Brainpool models three scenarios to understand the factors that are having the biggest impact on – and thereby make predictions for - electricity prices, revenues, energy source merit order, and emissions in the EU. Other parameters in the scope of their analysis include oil prices, gas prices, commodities markets, carbon taxes, and the EUA/emissions market. Clearly, collapsing prices are profoundly distorting … [Read more...]
Biogas and Biomethane’s untapped potential across the world
The IEA’s World Energy Outlooks have no doubt that electrification alone cannot meet our climate goals. That’s why natural gas continues to play a major role. But biogas and biomethane have the potential to replace 20% of that gas, says the IEA’s special report “Outlook for biogas and biomethane: Prospects for organic growth”. At present only a fraction of that is being utilised. Here the IEA summarises their comprehensive report. Costs are the … [Read more...]
Germany’s drive to decarbonise its prized heavy industry: an overview
Sören Amelang at Clean Energy Wire runs through their collection of factsheets, analyses, reports and interviews that have tracked German industry’s attempts to grapple with decarbonisation. The very high energy intensity required by industries like steel, chemicals and cement makes a simple switch to clean electricity – short of a total redesign of processes – impossible. But Germany wants to maintain, even extend, its world leadership in … [Read more...]
How underground CCS works: low leakage risk, 2%
It’s not just the high upfront costs and the absence of a profitable business model that’s stalling the take-off of Carbon Capture and Storage (CCS). There are fears that CO2 stored underground will leak over the thousands of years it needs to be sequestered. The companies that put it there will be long gone. If you aren’t around to take the blame and pay the penalty, why bother doing it properly? Stephanie Flude at Oxford University and Juan … [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...]
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...]
BP’s zero-carbon pledge: three major challenges
This month BP, one of the world’s largest oil and gas firms, announced its ambition to be a net zero emissions company by 2050. The promise extends to cutting the emissions of its customers too; after all, they’re the ones who are actually burning the fuel, not BP. So it aims to reduce the carbon intensity of its products by 50% by 2050 or sooner. Jules Kortenhorst, Tyeler Matsuo and Raghav Muralidharan at Rocky Mountain Institute take a look at … [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...]
