Study finds methane emissions from coal mines ~50% higher than previously thought

Green Car Congress

The amount of methane released into the atmosphere as a result of coal mining is likely approximately 50% higher than previously estimated, according to research presented at the recent annual meeting of the American Geophysical Union. The authors point out that less coal production doesn’t translate to less methane.

UK to award £54M to 15 projects developing innovative carbon removal technology

Green Car Congress

The UK government is awarding £54 million to 15 projects to develop technologies that remove carbon emissions from the atmosphere. The carbon dioxide can then be permanently stored or used in various products or applications. The biochar is rich in carbon and can be used as a fertilizer. Cambridge Carbon Capture Ltd.,

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.

BNEF: steel industry set to pivot to hydrogen in green push; additional $278B for clean capacity and retrofits

Green Car Congress

Steel production could be made with almost no carbon emissions through $278 billion of extra investment by 2050, according to a new report from research firm BloombergNEF (BNEF). Steel is responsible for around 7% of man-made greenhouse gas emissions every year and is one of the world’s most polluting industries.

CSIRO and partners to test Direct Injection Carbon Engine to reduce brown coal emissions by up to 50%

Green Car Congress

DICE involves converting coal or biomass into a water-based slurry (called micronised refined carbon, MRC) that is directly injected into a large, specially adapted diesel engine. The process has very high conversion efficiency >97% (LCA); he fuel choice determines the carbon footprint.

Rio Tinto validates BioIron process for low-carbon iron-making; biomass and microwave energy

Green Car Congress

Rio Tinto has shown the effectiveness of a low-carbon iron-making process using ores from its mines in Australia in a small-scale pilot plant in Germany, and is now planning the development of a larger-scale pilot plant to further assess its potential to help decarbonize the steel value chain.
