Assessment of the Leading Carbon Capture Companies

Here is a technical assessment of six companies leading the carbon capture space. These six companies are those whose core activity is carbon capture and storage (CCS). This includes Net Power and Quest that work exclusively in conjunction with fossil fuels, as well as the more flexible approaches of Carbon Engineering, Global Thermostat, Climeworks, and Carbfix. Assessment of Net Power and Quest Here are two examples of working CCS plants that are used in conjunction with fossil fuel-powered power plants. Both plants have been in operation for years and have amassed ample data to warrant scrutiny. These two companies are...

Companies Leading Negative Emissions Technology

The Biden administration's support for carbon capture and carbon removal technology is contributing to growing interest in companies working in this space.  Here are six of the best carbon capture and carbon removal companies for negative emissions technology: Net Power, Quest, Carbon Engineering, Global Thermostat, Climeworks and Carbfix.  In previous articles I have explored why we need to siphon carbon dioxide out of the atmosphere, assessed carbon capture technologies, and reviewed the cost and scalability of these technologies. Net Power and Quest are top companies with carbon capture and storage (CCS) technologies while the other four are working examples of carbon...

An Assessment of Carbon Removal Technologies

Carbon dioxide reduction (CDR) technologies have made great strides in the last ten years and there is support for the view that they are necessary and will play a major role in efforts to decarbonize our world. CDR includes direct air capture and sequestration (DACCS), carbon capture and utilization (CCU), and carbon capture and sequestration (CCS). This view is buoyed by pilot projects that have been deployed around the world, however, there is some disagreement about the cost and speed at which they can scale. It is likely that no one technology will dominate, and we will need to co-deploy...

The Costs and Scalability of Carbon Dioxide Removal Technologies

There are good reasons to believe that carbon dioxide reduction (CDR) technologies are viable, however, there are also legitimate concerns about such technologies.   An EASAC report concluded that NETs are unlikely to remove even several GtCO2/year after 2050. "Negative emission technologies may have a useful role to play but, on the basis of current information, not at the levels required to compensate for inadequate mitigation measures," the report stated. Low technological readiness, high costs, and negative effects on terrestrial and marine ecosystems are factors weighing against NETs, it said (EASAC, 2018). Cost is often presented as an important consideration. However,...

Nature Based Solutions to Climate Change

Nature-based solutions to climate change offer a number of ways to remove carbon dioxide from the air. These so-called natural climate solutions (NCS) involve conservation, restoration and land management actions that sequester carbon or avoid greenhouse gas emissions in landscapes and wetlands.    Advantages of Nature Based Solutions Costs Carbon capture is a critical part of efforts to reduce atmospheric GHG emissions that will enable us to keep temperatures below upper-temperature threshold limits of between 1.5 and 2 Celsius. However, Natural Climate Solutions are the most cost-effective negative emissions technology (NETs), this is particularly true of land management and forest management...

Decarbonization Through Electrification in Waterborne Transportation

All modes of transportation are gradually being converted to electric propulsion and this includes watercraft. Driven by ominous increases in atmospheric greenhouse gas emissions the move to decarbonize transportation through electrification is growing and while land and air travel get a lot of well-warranted attention, we also need to decarbonize vehicles that travel on water.  In recent years we have made major strides in electric cars, trucks, and buses as well as electric-powered aviation, but there are even greater opportunities to electrify watercraft because they are not as limited by space and weight as their air and land-based counterparts. Electrification is especially well...

What Aviation Efficiency can Teach us about the Power of Small Gestures

It is entirely appropriate that big ticket efforts to reduce global warming causing greenhouse gas emissions are at the center of global climate efforts, however, there is also a need for small gestures. Such actions can make a big difference if repeated often. Governments (nations and subnational), public companies and private organizations all have a critical role to play and so do individuals. Efficiency in the aviation industry is a good illustration of how seemingly small efforts can make a difference. Something as simple as painting a plane with a light color can have a major impact. White paint is...

Virtual Event – The Future of Sustainable Buildings Conference

The Future of Sustainable Buildings Conference will take place on October 27, 2020 1 p.m. - 2 p.m. (EDT). This free live virtual conference is subtitled "How Timber Will Define the Skylines of Our Future". Climate change will impact how we live and design in the future. To slow the rate of climate change we need to rethink the way we build. Sustainable design has many meanings, but  it starts with the recipe of building and the choice of healthy ingredients. The materials of a building and especially the structural materials represent the embodied carbon in a building’s life. Timber is...
