How much CO2 is saved by one tonne of green methanol instead of one tonne of grey methanol?
Best insight from top research papers
One tonne of green methanol saves a significant amount of CO2 compared to one tonne of grey methanol. Green methanol production processes, such as the coal-to-methanol process coupled with green hydrogen (CTMHPWE), offer substantial CO2 savings. The CTMHPWE process increases carbon utilization efficiency by 76.75% and reduces CO2 emissions by 56.61% compared to traditional CTM processes . Additionally, the production of green methanol from CO2 captured from mineral lime production can capture 160,000 tons of CO2 per year . These advancements in green methanol production contribute significantly to reducing CO2 emissions, making it a more environmentally friendly alternative to grey methanol.

What are the costs per ton of CO2 avoided of decarbonizing the buildings and construction sector?5 answersDecarbonizing the buildings and construction sector involves costs per ton of CO2 avoided. The International Cost Management Standard (ICMS) provides a framework for comparing life cycle costs and carbon emissions, aiding in decision-making. Building operations and materials contribute significantly to global CO2 emissions, with concrete, steel, and aluminum alone responsible for 23% of total emissions. Implementing new heating and cooling loops with heat pumps can reduce natural gas usage and lower carbon emissions by 10.8% to 38% compared to conventional systems. The cost of decarbonization is influenced by the Weighted Average Cost of Capital (WACC), with estimates ranging from £36.2 to £43.3 per ton of CO2 abated at different WACC levels. These insights highlight the importance of efficient strategies and standards in achieving cost-effective decarbonization in the buildings and construction sector.
How does bio-CO2 feedstock affect methanol that is going to be used for marine applications?5 answersBio-CO2 feedstock plays a significant role in the production of methanol for marine applications. Utilizing renewable methanol derived from waste biomass and CO2 can help reduce CO2 emissions in the shipping industry. This approach involves capturing CO2 from methanol production, which can be stored onboard for later use, contributing to a more sustainable fuel cycle. Additionally, blending bio-CO2 with other components like biomethanol in marine fuel can lead to improved properties, meeting standards set by the International Maritime Organization (IMO) for marine fuels. By integrating bio-CO2 feedstock into methanol production, ships can potentially achieve lower emissions and comply with future environmental regulations, making methanol a promising alternative fuel for marine applications.
What is the proposed mechanism of the reduction of CO2 to methanol?5 answersThe proposed mechanism of the reduction of CO2 to methanol involves several key steps. In the first step, the catalytically active species is formed through a reduction process, such as a four-electron-four-proton reduction of the initial catalyst. This active species then attacks CO2, leading to the formation of an intermediate [CoIII-CO22-]-. This intermediate undergoes protonation and further reduction to form [CoII-COOH]-. Subsequently, the hydroxyl group of [CoII-COOH]- is protonated by a carbonic acid, generating a critical species that can release carbon monoxide as an intermediate and produce methanol as the final product. Additionally, the concentration balance between CO2 and hydrosilanes around the catalytically active sites plays an important role in the selectivity of the product.
Can green methanol be used effectively in existing infrastructure designed for traditional fossil fuels?5 answersGreen methanol can be effectively used in existing infrastructure designed for traditional fossil fuels. It can be produced from renewable resources such as green hydrogen (H2) and captured carbon dioxide (CO2). The production of green methanol from renewable sources allows for a smooth transition between fossil fuels and renewables, without the need to change the existing infrastructure. Innovative technologies such as gas-heated reforming (GHR) coupled with carbon capture and storage platforms (CCS) can promote sustainable methanol operations and improve energy and resource efficiencies. Additionally, the production of methanol from different fossil fuels, such as natural gas and vacuum residue, can be compared in terms of energy, environmental, and economic factors, with the potential for CO2 capture and utilization. The utilization of green methanol can help reduce carbon emissions and contribute to the reduction of CO2 footprint, while also satisfying environmental requirements and economic constraints.

How much 1 ton of metal can help reduce greenhouse gas emissions?5 answers1 ton of metal can help reduce greenhouse gas emissions by utilizing lightweight design principles, which reduce the amount of new metal required to meet demand for services. Exploiting lightweight design opportunities for various steel and aluminum products alone could potentially reduce global steel requirements by 5% and global aluminum requirements by 7%. If similar savings were possible for all steel and aluminum products, total material requirements could be reduced by 25-30%. Additionally, using secondary (recycled) metal sources instead of primary sources in metal production can lead to significant energy savings and greenhouse gas emissions reduction. However, the availability of scrap metal for recycling is limited due to long product lifespans and low end-of-life recycling rates. Therefore, while 1 ton of metal can contribute to reducing greenhouse gas emissions through lightweight design and recycling, the overall impact depends on the specific metal and the extent of implementation of these strategies.
