Coal-based electronics: A potential usurper to silicon's throne?

Graphene may be the poster child of thin film electronics, and silicon the current king of materials for semiconductors, but if scientists from MIT get their way, graphene's humble cousin, coal, could soon be giving them both a run for their money. For the first time, electronic devices have been created from thin films of coal and the research points to a range of uses that this cheap and abundant material could have in electronic devices, solar panels, and batteries.Read More

Hybrid system could clean up coal power

Even though 2015 saw the biggest decline in coal usage around the world on record according to Greenpeace, the use of the material is still thriving globally. In fact, according to the US Energy Information Administration, global coal consumption was at about eight billion short tons in 2012 (around 7.2 billion tonnes), the most recent year for which the agency provides statistics. So if coal isn't going away any time soon, what is there to do about the fuel source that is often blamed for pollution and global warming due to carbon emissions? Make it more efficient. And that's exactly what a new hybrid energy system out of MIT could do.Read More

Researchers produce new fuel from coal dust and algae

Researchers at the Nelson Mandela Metropolitan University (NMMU) in South Africa have developed a new fuel, known as Coalgae. Made from a combination of algae and coal dust, the latter of which is a waste product, the fuel could have a significant positive impact on the environment.Read More

University of Washington fusion reactor promises "cheaper than coal" energy

In the 21st century, the world lives with two futures ahead of it – one of looming energy shortages, and another of godlike energy abundance. The key to this whether it’s possible to turn fusion reactor technology from a laboratory exercise into a real-world application. Engineers that the University of Washington are working on a fusion reactor that, when scaled up, could produce energy on a practical scale, yet at a cost rivaling that of a conventional coal-powered plant.Read More

GE's Mine Cruiser puts safety before beauty

The depths of a coal mine couldn't be considered ideal driving conditions for most vehicles, but the Mk7.0 TIER 3 Mine Cruiser isn't most vehicles. GE recently announced that it has delivered its 500th Mine Cruiser, which is a four-wheel drive utility vehicle capable of carrying up to 14 passengers, yet is built to operate safely in the vast galleries of modern underground coal mines.Read More

Analysts say renewable energy now cheaper option than new fossil fuels in Australia

In 2008, the Garnaut Climate Change Review ranked Australia as the highest per capita emitter of greenhouse gases of any OECD country and amongst the highest in the world. One of the reasons for the country's high carbon footprint is its reliance on coal for electricity generation – 54 percent of it, according to the Australian Coal Association. But a new study by Bloomberg New Energy Finance (BNEF) points to a cleaner energy future with the claim that unsubsidized renewable energy is now a cheaper option for electricity generation than new coal- or gas-fired power stations.

Shale gas and atmospheric CO2: help or hindrance?

Since peaking in 2005, US domestic energy CO2 emissions have fallen by 8.6 percent. A new report asserts that up to half of this reduction may be down to "energy switching," as generators switch from coal to shale gas (partly on cost grounds), which emits about half the CO2 when burned. Yet the same report, from the Tyndall Centre for Climate Change Research, questions the wisdom of touting shale gas as a low-carbon technology, with its authors actually asserting that "the exploitation of shale gas reserves is likely to increase total emissions." How so?Read More

CSR project aims to create a high-speed, carbon-neutral steam-powered locomotive

You might think that a coal-burning locomotive built in 1937 had nothing left to offer the modern rail industry, short of being a nice museum piece. In the case of Locomotive 3463, however, that appears to be far from true – now in the hands of engineers from the Coalition for Sustainable Rail (CSR), it is set to become the world’s first carbon-neutral higher-speed locomotive. It won’t be electric, however. Instead, it will run on steam generated by the burning of biocoal.Read More

New process allows fuel cells to run on coal

Lately we’re hearing a lot about the green energy potential of fuel cells, particularly hydrogen fuel cells. Unfortunately, although various methods of hydrogen production are being developed, it still isn’t as inexpensive or easily obtainable as fossil fuels such as coal. Scientists from the Georgia Institute of Technology, however, have recently taken a step towards combining the eco-friendliness of fuel cell technology with the practicality of fossil fuels – they’ve created a fuel cell that runs on coal gas.

New research shows real government subsidies for clean and dirty power

How can you tell when a politician is lying? First check to see if his/her lips are moving. New research has revealed that despite what they would have you believe, the world’s governments subsidize the fossil fuel sector far more than they do renewables and biofuels. Indeed, the assistance delivered to the oil, coal, and other fossil fuel sectors makes a mockery of claims that government is serious about reducing carbon emissions. Hey folks, that’s YOUR MONEY!Read More
