Manmade biomass coal offers storage and fuel

A new machine dubbed the "Black Phantom" can turn biomass into manmade coal.

Carbonscape, a New Zealand-based start-up, describes its invention as an industrial-sized microwave that can cook plant waste, wood waste, and "even sewage" into coal.

Carbonscape also claims that the machine captures and stores more carbon than the amount of carbon generated by the electricity needed to power it for the process.

Why would anyone want to make more coal when humans are desperately trying to get out from under the carbon dioxide mess we've been making since the Industrial Revolution?

The invention … Read more

Swedish utility targets carbon-neutral electricity

CAMBRIDGE, Mass.--Lars Josefsson is the CEO of an electricity utility and a self-described climate activist.

He leads Vattenfall, a Swedish state-owned utility that has set a goal of making its power generation carbon-neutral by 2050. He delivered the opening keynote address at the MIT Energy Conference here on Saturday.

Vattenfall, which means waterfall in Swedish, already gets 22 percent of its electricity from renewable sources, largely hydropower and offshore wind in Sweden, and an additional 31 percent from nuclear energy.

In the utility industry, Vattenfall is well know for being the first to test carbon capture and storage technology … Read more

Is carbon storage just a pipe dream?

Researchers are committing billions of dollars to technologies that take carbon dioxide out of the atmosphere and store it underground, as more scientists and environmentalists question the wisdom of these plans.

Researcher Anders Hansson's at Linkoping University's Department of Technology and Social Change in Sweden this week published a study that concluded that the risks and complications of carbon capture and storage are grossly underestimated, according to a report in ScienceDaily.

"In full scale, this technology only exists in the imaginations of the people developing it," Hansson said. "It's overly optimistic to place such … Read more

DOE goes cave hunting to pump carbon underground

The U.S. Department of Energy awarded $126.6 million in grants on Tuesday to test carbon capture and storage in underground caverns.

Two sites in Ohio and California will try to verify that carbon dioxide gas can be pumped in geological formations and stored safely. The CO2 will be delivered from an ethanol plant in Ohio and a power plant in California.

The grants are subject to approval from Congress. When private money is included, the amount spent on the projects will be about $180 million over 10 years, the DOE said.

The Bush Administration and many other energy … Read more
