In carbon markets such as the EU ETS participants must monitor and report their emissions and ultimately pay for them. Biomass occupies a unique place. It is well positioned to be a net-zero emissions energy source for hard-to-abate sectors. Coupled with effective on-site carbon capture technologies, it can be carbon negative. And there is a great diversity of project types involving forestry, biochar kilns, waste-to-energy, carbon capture and … [Read more...]
Study: Marine Carbon Removal, and the Offshore Wind and Wave Energy to power it
Ocean-based carbon dioxide removal makes a lot of sense. The oceans are already carbon sinks that absorb about 30% of global carbon emissions. And the concentration of CO2 is higher in water than in air. Caitlin McDermott-Murphy at NREL looks at a new study of the technologies under development, and the opportunities for offshore wind and wave energy to power it. There are nature-based solutions like vast seaweed or algae farms. There are also … [Read more...]
Gulf States are investing in Carbon Capture to maintain Hydrocarbon business
The Gulf region wants to maintain their substantial revenues from hydrocarbons in a decarbonising world. One way to do that is to invest in carbon capture, to make cleaner and more marketable fossil fuel products. Megren Almutairi and Karen Young at CGEP look at their current plans and future prospects. Right now, about 10% of CO2 captured globally is in the industrial facilities of the Gulf States. Their national oil companies boast some of the … [Read more...]
Chemicals Industry needs Sustainable Feedstocks to complete their net-zero journey
The chemicals industry is crucial to decarbonisation because it’s a major supplier of products to other industries. Many are very high profile - such as automotive, construction, food, and personal-care – so scrutiny will be high. It’s why two-thirds of Europe’s largest chemical end users in Europe are committed to reducing greenhouse-gas emissions by 2030, and over a third have pledged net-zero targets by 2050. But although chemicals industry … [Read more...]
Making solid fuel from captured CO2 (with a 96% conversion rate)
What if CO2 could be captured and, rather than locked away underground for eternity, turned into a stable powder that can be used in fuel cells to produce electricity? David Chandler at MIT describes research there and at Harvard that has demonstrated a new process that has a 96% conversion rate. It’s been tried before, but the conversion rates were an unusable 20%. The CO2 is converted into formate and used like hydrogen or methanol (both strong … [Read more...]
China can learn from the EU about power market design and infrastructure build-out
How will China integrate its growing Variable Renewable Energy generation and create a nationwide energy system that avoids the risks of curtailment, stranded assets and blackouts? A good place to start is to learn from Europe. Helen Farrell at ECECP summarises their report that uses the European experience to model scenarios for China. China’s key challenges is that its power market lacks an effective auxiliary service market, a capacity market, … [Read more...]
Green Methanol: an alternative fuel for heavy vehicles and shipping?
It’s very early days but pilot projects for green methanol are underway, explains Gabi Thesing writing for WEF. It’s a low-carbon fuel that can be produced from renewable sources such as biomass or using carbon capture. Compared to traditional fossil fuels it can reduce CO2 emissions by 60-95%, nitrogen oxide by 60-80%, and almost completely eliminate sulphur oxide and particulate matter emissions. Green methanol can be blended with traditional … [Read more...]
Fossil producer UAE to host COP28: what are Gulf states doing to decarbonise?
COP28 in November is being hosted by the United Arab Emirates (UAE), a major oil and gas producer. The COP President will be Sultan Al Jaber, the CEO of ADNOC, one of the world’s biggest oil companies. It’s attracted heavy criticism from many quarters. Robin Mills at the Center on Global Energy Policy reviews the contradictions inherent in a leading fossil producing nation hosting the world’s most important decarbonisation forum. The Gulf states … [Read more...]
How much Carbon Capture does the EU need from LULUCF, BECCS, Industrial CCS, DACCS?
How much carbon capture does the EU need to 2050? Robert Jeszke and MichaĹ‚ Lewarski at The National Centre for Emissions Management (KOBiZE), writing for the Florence School of Regulation, start by pointing out that mainstream estimates vary significantly, from 50-300 Mt CO2 to 1,300-1,500 Mt CO2. They then present their study (their estimate is 550 Mt CO2). The study highlights the importance of BECCS (Bioenergy with Carbon Capture and Storage): … [Read more...]
Event summary: “Bioenergy after REDIII – sustainable, climate neutral fuels for industry, transport and negative emissions”
Sara Stefanini provides a written summary of our panel discussion held on Wednesday 4th October 2023. It’s a full summary of the 75 minute discussion, and begins conveniently with a summary of the highlights. Under the recently revised Renewable Energy Directive (REDIII) bioenergy can be counted towards the renewable energy targets – provided that it meets strict sustainability criteria. Bioenergy already accounts for 60% of the EU’s renewable … [Read more...]
Electrochemical Carbon Capture: a cheaper one-step process, power by clean energy
Carbon capture is expensive. Hence continuous attempts in laboratories around the world to find new ways to capture CO2 that are simpler and cheaper. One problem with the traditional method is that it is a two-step process, and energy intensive (therefore powered by high-heat fossil fuels). Jennifer Chu at MIT describes a new electrochemical method that separates out CO2 in a single step, and it’s powered by clean energy. It’s particularly … [Read more...]
Germany plans for Carbon Capture in Industry: emissions, potentials, costs
In the first article of this series, Simon Göss and Hendrik Schuldt at carboneer gave the background to Germany’s new drive for carbon capture, and summarised the industrial sectors that will be its focus. Here, the authors analyse the emission profiles of German industries (in particular: steel, cement, lime, chemicals, waste incineration) and the associated CCS potentials and costs. The first thing to note is that it’s the process emissions … [Read more...]
Carbon Capture: how all Germany’s captured CO2 can be used by the Chemical industry
The German government is promising to publish a strategy on carbon capture, opening a door that has previously been closed to developing this technology. In the first of a series of articles, Simon Göss and Hendrik Schuldt at carboneer look at why the nation is changing its mind, before laying out the reasons why carbon capture will be essential for Germany to meet its emissions goals. Unlike the power grid, there’s no easy way to decarbonise … [Read more...]
Norway’s Sleipner and Snøhvit CCS: problems expose limitations of the science, regulations and multi-decade commitment
The offshore carbon capture and storage (CCS) projects of Norway’s Sleipner and Snøhvit are often cited as good case studies for the viability of the technology. Other CCS hubs are being proposed from Malaysia to the North Sea to the Gulf of Mexico, larger by factors of 10 or more. But how viable are they? Grant Hauber at IEEFA summarises his in-depth report on the risks. Both Sleipner and Snøhvit, operating since 1996 and 2008 respectively, have … [Read more...]
Carbon Capture rates of 60% sound impressive. But rising carbon prices could still make you commercially unviable
Mainstream scenarios state the unavoidable need for continued use of fossils through to 2050. For the world to stay within its carbon budget, that means the unavoidable need for carbon capture and plugging “fugitive” leaks. Chris Bataille at the Center on Global Energy Policy flags up the danger that new CCS projects with seemingly impressive capture rates of up to 60% may nevertheless become commercially unviable as carbon prices rise: that … [Read more...]
