  • Carbon capture and storage: research conclusions?

    Carbon capture and storage: research conclusions?

    Carbon capture and storage (CCS) prevents CO2 from entering the atmosphere. Options include the amine process, blue hydrogen, novel combustion technologies and cutting edge sorbents and membranes. Total CCS costs range from $80-130/ton, while blue value chains seem to be accelerating rapidly in the US. This article summarizes the top conclusions from our carbon capture…

  • Global CCS Projects Database

    Global CCS Projects Database

    Over 400 CCS projects are tracked in our global CCS projects database. The average project is 2MTpa in size, with capex of $600/Tpa, underpinning over 400MTpa of risked global CCS by 2035, up 10x from 2019 levels. The largest CO2 sources are hubs, gas processing, blue hydrogen, gas power and coal power. The most active…

  • CarbonCure: concrete breakthrough?

    CarbonCure: concrete breakthrough?

    CarbonCure injects CO2 into concrete during the mixing process, where it mineralizes. The resultant product can most likely save 4-6% of the CO2 intensity of finished concrete. Question marks are explored in the data-file.

  • CO2 capture: a cost curve?

    CO2 capture: a cost curve?

    This data-file summarizes the costs of capturing CO2. The lowest-cost options are to access pure CO2 streams that are simply being vented at present. Next are blue hydrogen, steel and cement, which could each have GTpa scale. Power stations place next, at $60-100/ton. DAC is carbon negative but expensive.

  • CO2 electrolysis: the economics?

    CO2 electrolysis: the economics?

    Carbon monoxide is an important chemical input for metals, materials and fuels. Could it be produced by capturing CO2 from the atmosphere or using the amine process, then electrolysing the CO2 into CO and oxygen? We find 10% IRRs could be achievable at $800/ton, competitive with conventional syngas.

  • Biomass accumulation: CO2 fixed by trees and energy crops?

    Biomass accumulation: CO2 fixed by trees and energy crops?

    Different plant species fix 3-30 tons of CO2 per acre per year, as they accumulate biomass at 2-40 tons per hectare per year. The numbers matter for biofuels and for nature-based solutions. Hence this data-file compiles technical data into CO2 and biomass accumulation by plant species and by tree species, in different regions globally.

  • Carbon offsets: costs and leading companies?

    Carbon offsets: costs and leading companies?

    This data-file screens 30 companies that are offering CO2 offsets to consumers and commercial customers. Costs vary from $4-40/ton, as a function of project types and organizational structure. We recently used the data-file to offset 200T of CO2, in the most economical, tax-efficient and personally resonant way.

  • Ventures for an Energy Transition?

    Ventures for an Energy Transition?

    This database tabulates c300 venture investments, made by 9 of the leading Oil Majors. Their strategy is increasingly geared to advancing new energies, digital technologies and improving mobility. Different companies are compared and contrasted, including the full list of venture investments over time.

  • Heavy truck costs: diesel, gas, electric or hydrogen?

    Heavy truck costs: diesel, gas, electric or hydrogen?

    Heavy truck costs are estimated at $0.14 per ton-kilometer, for a truck typically carrying 15 tons of load and traversing over 150,000 miles per annum. Today these trucks consume 10Mbpd of diesel and their costs absorb 4% of post-tax incomes. Electric trucks would be 20-50% most costly, and hydrogen trucks would be 45-75% more, which…

  • Restoring soil carbon: the economics?

    Restoring soil carbon: the economics?

    We model the economics for conservation agriculture to restore soil carbon. 5-30T of CO2 can be sequestered per acre per year, while deflating farm costs by 36-73% and raising yields 10-20%. This would transform crop-growing economics from marginal to material.
