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...]
Gas infrastructure leaks methane: fix it, or accelerate to clean energy
Natural gas, because it’s low-carbon, is being used as a bridge fuel away from the old fossil fuel world. But there are two main problems. The infrastructure leaks methane (the main component of the gas) which is 25 times more potent than CO2 over a 100-year period (and 86 times over a 20-year period!). And, crucially, nobody is properly measuring those leaks. That means policy makers are growing the gas mix without knowing by how much it’s … [Read more...]
Grid switchgear uses SF6, the world’s most potent greenhouse gas. How do we regulate it?
Sulphur Hexafluoride (SF6) is described as the world’s worst greenhouse gas. It’s 23,500 times more potent than CO2. Global annual emissions are 8,100 tonnes, equivalent to the CO2 emissions of 100m cars. It has an atmospheric lifetime of over 1,000 years and its installed base is expected to grow by 75% by 2030. 80% of all SF6 is used in gas insulated switchgear, a vital component of the grid (isolating and protecting different sections), so … [Read more...]
Decarbonising industry: how much policy-driven adoption is needed to let the market take over
Decarbonising industry is one of the world’s greatest challenges. The costs, today, are huge and therefore the technology adoption required has hardly started. But several technologies already exist. Gbemi Oluleye at Imperial College (UK) explains the first step is to measure the market size for each sub-sector, then estimate how much policy-driven adoption is required to achieve the cost reductions that make the change viable. After that, no … [Read more...]
Aviation’s multiple challenges: from renewable fuels to non-CO2 emissions
Barely the first steps towards climate-neutral aviation have been made. High energy density renewable fuels are needed, and at scale. But even as they become available, hard-to-abate industries will be queuing up to buy them first. And then there’s reducing the "non-CO2 effects" that, according to Germany's environment agency (UBA), can harm the climate twice as much as direct CO2 emissions: condensation trails, particles and other greenhouse … [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...]
Extract CO2 from our air, use it to create synthetic fuels
Carbon Capture needs to take off, but nobody knows how it’s going to happen. We need innovation, scrutinised, tested and funded. Jim Conca looks at a method of extracting CO2 directly from the air that’s being pioneered by Carbon Engineering in Canada, backed by private investors and government agencies. It grew out of academic work at the University of Calgary and Carnegie Mellon University. It’s “Direct Air Capture” system can remove a ton of … [Read more...]
Will the German Climate Protection Programme 2030 miss its own targets?
On Friday, 20 September, the German Climate Cabinet agreed on the guidelines for German climate policy for the coming decade, set against the backdrop of EU targets. The core topic was additional CO2-pricing in the mobility and heating sectors. From 2021 a CO2-price of €10/ton will apply to the German transport and buildings sectors. The price will rise to €35/ton until 2025. But Simon Göss says the national emission trading system and new … [Read more...]
Calculating the effect of $50/tonne CO2 on energy prices
Despite much debate, governments are hesitant to raise – or even impose – carbon pricing, worried about the direct impact it will have on businesses and consumers.To help understand its effect Severin Borenstein at the Energy Institute at Haas has crunched the numbers of a $50/tonne CO2 price, very expensive by today’s standards. He’s calculated the actual price increases on a gallon of petrol/gasoline, gas- and coal-fired generation, and natural … [Read more...]
Rising green taxes: making them acceptable to all
Environmental taxes hurt low-income households the most because they spend a much higher proportion of their income on heating oil, natural gas, and electricity. It’s why Spain has low green taxes, far below the EU average. Mark Dwortzan at MIT explains how researchers from the U.S., Germany and Spain teamed up to show that low-income households can benefit from environmental taxes provided those tax revenues are carefully redistributed in their … [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...]
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...]
Time for tech-neutral incentives if renewables growth won’t stop climate change?
In 2018 energy use grew 2.9% and emissions 2%. That means renewables are not keeping up with energy’s growth: it will need a four-fold increase in wind and solar’s growth to do so, says Schalk Cloete. There’s more: to cut global CO2 emissions by the 3% per year we need to meet the Paris goals wind and solar growth rates must increase by over an order of magnitude. He reviews the evidence and concludes that current technology-forcing policies – … [Read more...]
BP Review of 2018: record CO2, energy use as gas outstrips wind & solar
Energy use grew at 2.9% in 2018, the largest rise since 2010. It’s what happens when economies grow. But gas, oil and coal's contribution to that growth saw global CO2 emissions rise by 2% in 2018, the largest year-on-year increase in seven years. Wind and solar growth, driven by China though slowing in the US, EU, and India, achieved its second fastest rate on record - but still lagged behind gas additions. These are not the trends we need to … [Read more...]
