Dirt-cheap catalyst may lower fuel costs for hydrogen-powered cars

Researchers seeking to make hydrogen a less expensive fuel for cars have upgraded a catalyst nearly as cheap as dirt — molybdenum disulfide, ‘molly’ for short — to stand in for platinum, a rare element with the moonlike price.

“Walking” Oil Rigs Can Make Drilling Faster, Cheaper, Safer

The current malaise in the oil industry has placed a renewed emphasis on measures to cut costs, as producers struggle with the realities of sub $50-a-barrel oil. One of the more interesting innovations in the oil patch is the “walking” oil rig that can easily move from one well to the next, thus saving the operator the expensive and time-consuming process of disassembling and reassembling rig components.

Reproducible research for biofuels, biogas

New research presents a virtual package of data for the production of biogas, which is promising for use in biofuels. Biogas is the production of methane through the anaerobic digestion (fermentation) of organic matter. The work here provides not only an enormous amount of, freely available, data; but is also presented in a reproducible, reusable containerized form, allowing scientists to recreate the experiments at the touch of a button.

American Innovation Can We Turn CO2 Into Fuel?

The boundary between science and science fiction is blurring, as researchers are hard at work developing methods to capture the problematic greenhouse gas carbon dioxide from our atmosphere and turn it into diesel.

Used cigarette butts offer energy storage solution

Scientists in South Korea have developed a new way to store energy that also offers a solution to a growing environmental problem. Reporting their findings in the IOP Publishing journal Nanotechnology, the research team successfully converted used cigarette butts into a high performing material that could be integrated into computers, handheld devices, electric vehicles and wind turbines to store energy.

Why Tesla’s announcement is such a big deal: The coming revolution in energy storage

As was widely expected, Tesla announced that it is offering a home battery product, which people can use to store energy from their solar panels or to backstop their homes against blackouts, and also larger scale versions that could perform similar roles for companies or even parts of the grid.

We need energy technology, not ideology

Let’s keep burning coal; after all, it is a “way of life,” therefore we must continue. No, wait: Let’s eliminate fossil fuels altogether right now and make the world a better place. These two perspectives could not be more opposite, and yet both are the same. They are uninformed. We are not using coal the way we were even 30 years ago and have advanced power production efficiency enormously — but we are still emitting carbon dioxide.
