OSU team develops process to clean coal mine drainage and extract rare earth elements

Green Car Congress

Researchers at The Ohio State University have developed a novel process to clean coal mine drainage and extract rare-earth elements from it. Coal mine drainage (CMD) impairs tens of thousands of kilometers of U.S. CMD, coal mine drainage; TEP, trap-extract-precipitate. —Miranda et al. Miranda et al. —Jeff Bielicki.

Converting Coal Power Plants to Nuclear Gains Steam

Cars That Think

On a planet aspiring to become carbon neutral, the once-stalwart coal power plant is an emerging anachronism. It is true that, in much of the developing world, coal-fired capacity continues to grow. But in every corner of the globe, political and financial pressures are mounting to bury coal in the past.

Siemens Energy, FFI and GeoPura developing prototype ammonia cracker to produce hydrogen

Green Car Congress

The traditional process of producing ammonia has used “grey” or “black” hydrogen from either natural gas or coal. The technology could then be scaled up for future markets, including industry, heat, and grid-scale power generation. Siemens Energy has proven experience of innovation with ammonia. million (US$1.8-million)

Study findings suggest that switching from coal to natural gas would do little for global climate

Green Car Congress

While coal use causes warming through emission of heat-trapping carbon dioxide, it also releases comparatively large amounts of sulfates and other particles that, although detrimental to the environment, cool the planet by blocking incoming sunlight. —Tom Wigley. Methane is an especially potent greenhouse gas. degree Celsius).

How to Hasten India’s Transition Away From Coal

Cars That Think

Greenhouse gas emissions will certainly grow too, because India’s energy generation is dominated by fossil fuels—coal-fired power plants for electricity, coal- and gas-fired furnaces for industrial heating, liquid petroleum gas for cooking, and gasoline and diesel for transportation. costs less than fossil-fuel-based electricity.

WHO attributes more than 1 in 4 deaths annually of children under 5 years to unhealthy environment

Green Car Congress

WHO estimated in 2012 that 26% of childhood deaths and 25% of the total disease burden in children under five could be prevented through the reduction of environmental risks such as air pollution, unsafe water, sanitation and inadequate hygiene or chemicals. —“Don’t Pollute My Future”.

DOE awards $35M to 12 ARPA-E projects to reduce methane emissions; 5 on natural gas engines

Green Car Congress

The US Department of Energy (DOE) announced $35 million in funding for twelve projects focused on developing technologies to reduce methane emissions in the oil, gas, and coal industries. The system will significantly increase methane conversion efficiency and comply with future stringent nitrous oxide regulations.
