Though still heavily reliant on oil and gas, Norway can claim to be a central piece in Europe’s decarbonisation puzzle, explains Tshin Ilya Chardayre writing for the IFRI Centre for Energy & Climate. Norway’s substantial hydropower infrastructure gives it a reservoir storage capacity that could account for 10% of EU-wide energy storage needs by 2050. That would require international transmission cables and power markets, the development of … [Read more...]
Hydrogen, CCS, and more: without new clean energy technologies we cannot hit our 2050 emissions targets
The flagship 400-page report, Energy Technology Perspectives 2020, is another salvo from the IEA to concentrate the minds of the world on new technologies and their roll out. That’s because transforming electrification and the power sector alone, where most of the progress is happening, will only get us one-third of the way to net-zero emissions by 2050. The IEA has analysed over 800 new technology options. The most important categories – … [Read more...]
“Electro-swing cell” captures CO2 direct from the air
The problem with capturing carbon from a power plant is that the CCS system is itself huge, expensive, consumes a lot of energy, and only works on exhaust streams with high concentrations of CO2. What’s more, to meet global CO2 targets, total atmospheric CO2 has to be reduced, not just held at today’s concentrations by capturing new emissions alone. Writing for MIT, Nancy Stauffer explains how researchers there are piloting an “electro-swing … [Read more...]
Enhanced Weathering: crushed rocks spread on farmland can capture billions of tons of CO2/year
Enhanced Weathering is a carbon capture process that could remove over 2bn tons of CO2 each year (for comparison, the U.S. emitted 5.3bn in 2018), explains Benjamin Houlton at the University of California. Silicate minerals exposed to the weather have been sequestering atmospheric carbon and turning it into rock since the dawn of time, but it’s a process that normally takes thousands of years. This period can be cut to two years by grinding … [Read more...]
Little progress decarbonising Industry. Renewables can be the answer
The decarbonisation of heavy industry is making little progress. There are two main reasons. Firstly, there are no easy technology wins. Efficiency and carbon capture have been the favoured options. But efficiency gains have their limits, and carbon capture is still proving very expensive. Secondly, governments don’t want their home industries to lose competitiveness incurring costs reducing emissions. Dolf Gielen and Paul Durrant at IRENA say a … [Read more...]
Optimising Cyanobacteria for carbon fixation and biofuels
The landscape can be changed for energy transition technologies by research breakthroughs, and that includes work on bacteria and proteins. The National Renewable Energy Laboratory (NREL) and its partners have been running experiments on cyanobacteria. These single-cell organisms, also using photosynthesis, fix carbon dioxide twice as efficiently as plants. They grow rapidly, doubling their numbers in three hours. The first step is to understand … [Read more...]
Tipping Points reached for Solar, Wind, Batteries, EVs. What of the other Clean Energy techs?
History shows a disruptive technology’s tipping point can be under 5% of market share, that’s all it takes. The number of horses in use peaked in the U.S. once car ownership reached 3%. Gas lighting in the UK peaked with electric lighting at just 2% of the market. Landline phones in the U.S. fell precipitously after mobiles captured 5% of the market. Ji Chen and Koben Calhoun at RMI argue the tipping point has already been passed for solar, wind, … [Read more...]
Promises of future tech make hitting the 2°C target harder: a history
Writing for Carbon Brief, Duncan McLaren at Lancaster University runs through the history of climate negotiations to show that, over “five phases”, the continuous overhauling of models and target-setting have always resulted in promises to reverse emissions sometime in the future, a poor substitute for the real job of cutting emissions now. His main criticism is aimed at future carbon capture (CCS, BECCS) and net-zero-by-2050 policies: anything … [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...]
Coronavirus: economic stimulus plans open a door for clean energy
We’re facing an unexpected global economic slump thanks to the coronavirus sweeping across the world. In response, governments everywhere are tabling stimulus packages to get us through what is a temporary but severe drop in economic activity. That stimulus could be used, as it usually is, to get us back on the same path. But it should be used to steer us further and faster onto the new path of clean energy, says Fatih Birol, Executive Director … [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...]
Germany must put CCS back on the table, says Merkel
Carbon Capture has not been popular in Germany. The public are largely opposed, political parties are split, and Federal States are not approving new projects. Germany has only four operations, and only one has injected anything (not much) into the ground. Now Chancellor Merkel wants it back on the table, along with a public debate. Julian Wettengel at Clean Energy Wire runs through the reasons for the opposition (an excuse to keep coal plants … [Read more...]
Norway’s “Northern Lights” project: creating the CCS business model
Northern Lights, a carbon capture and storage (CCS) project backed by the Norwegian government, is drilling test wells in the North Sea to find suitable places to store CO2. Project partners include Shell and Total, and others are joining them. CO2 will be shipped to an onshore terminal from which it is piped to the subsea wells. Once established, the plan is for other European countries to send their CO2 too. The project will also create the … [Read more...]
10 Carbon Capture methods compared: costs, scalability, permanence, cleanness
We need to understand carbon capture, storage and utilisation (CCUS) better. To do so, this article looks at 10 methods and estimates how much CO2 each will take out of the atmosphere by 2050, and the cost per tonne. In their list the authors, Ella Adlen and Cameron Hepburn at the University of Oxford, cover the industrial (e.g. CO2-EOR, synfuels) to the biological (e.g. forestry, soil carbon sequestration). They say there are six that can be … [Read more...]
An independent Global Energy Forecast to 2050 (part 4 of 5): Nuclear, biomass and CCS
Schalk Cloete is creating his own 5-part independent Global Energy Forecast to 2050, to compare with the next IEA World Energy Outlook, due in November. To make his predictions he has created simulations of cost-optimal technology mixes and made his own assumptions over the drivers that will affect them: policy, technological progress, demand growth and behavioural change are all included. If nuclear, biomass and CCS take off they will … [Read more...]
