Novel adaptation for existing blast furnaces could reduce steelmaking emissions by 88%; closed-loop carbon recycling

Green Car Congress

This reduction is achieved through a closed-loop carbon recycling system, which could replace 90% of the coke typically used in current blast furnace-basic oxygen furnace systems and produces oxygen as a byproduct. If implemented in the UK alone, the system could deliver cost savings of £1.28 A double perovskite, Ba 2 Ca 0.66 Kildahl et al.

Study finds GHG emissions from corn ethanol now 46% lower than gasoline

Green Car Congress

A new study by a team from Environmental Health & Engineering (EH&E) has found that greenhouse gas emissions from corn ethanol are 46% lower than those from gasoline—a decrease in emissions from the estimated 39% done by previous modeling. gCO 2 e/MJ) which is 46% lower than the average carbon intensity for neat gasoline.

Woodside joins Japanese consortium to study exporting carbon-neutral hydrogen as ammonia

Green Car Congress

Australia-based Woodside has signed an agreement with Japanese companies JERA Inc, Marubeni Corporation and IHI Corporation to undertake a joint study examining the large-scale export of hydrogen as ammonia for use decarbonizing coal-fired power generation in Japan. Green hydrogen is produced from renewable energy using electrolysis.

U-M researchers challenge USPS EV environmental study

Green Car Congress

A new University of Michigan study finds that making the switch to all-electric mail-delivery vehicles would lead to far greater reductions in greenhouse gas emissions than previously estimated by the US Postal Service (USPS). The Postal Service said in February that at least 10% of the new mail trucks would be electric.

Alcoa exploring technology to reduce carbon emissions in alumina refining; MVR powered by renewable energy

Green Car Congress

The Australian Renewable Energy Agency (ARENA) is awarding Alcoa of Australia $8.8 million) toward testing the potential use of renewable energy in a Mechanical Vapor Recompression (MVR) process for alumina refining. The development project has the potential to reduce carbon emissions in the alumina refining process significantly.

Stanford study finds current carbon capture technology inefficient & increases air pollution

Green Car Congress

A study by Mark Z. Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. All sorts of scenarios have been developed under the assumption that carbon capture actually reduces substantial amounts of carbon.
