Hydrostor is developing truly massive grid storage in watery caverns

Read the full story at Canary Media.

Dozens of companies are building breakthrough technologies to store clean power for hours on end. Canadian startup Hydrostor could beat them to market with a combination of water and caves.

After operating its technology in Ontario’s wholesale market for two years, Hydrostor last week won a government grant worth 4 million Canadian dollars ($3.2 million) to pay for design work for a project that could deliver as much as 500 megawatts. That’s more capacity than the largest lithium-ion battery plants that are now operating. But Hydrostor’s facility would be able to discharge for up to 12 hours, longer than is typically cost-effective for batteries.

Green ‘liberty’ bonds: The American way to win the war on climate change?

Read the full story at Canary Media.

President Joe Biden has an aggressive plan to decarbonize the U.S. economy. But his administration hasn’t yet provided many specifics on how it plans to leverage public funding to drive greater private capital investment in the green infrastructure needed to reach its goals.

Bryan Garcia, president and CEO of the Connecticut Green Bank, thinks that a modern, green-tinged version of Liberty Bonds, the U.S. government war bonds from World War I and World War II, could be a valuable model for the federal government — particularly if Connecticut’s recent experience with it can be replicated at a national scale.

Connecticut Green Bank’s $25 million green “liberty” bond issuance on Thursday, its latest to support rooftop solar and energy efficiency projects in the state, was oversubscribed by nearly a factor of four, Garcia said.

The Dallas-based luxury retailer has formed a new team that is expected to infuse environmental considerations and sustainability into all parts of its business. The three-person team will set up task force groups across departments and will report to chief people officer Eric Severson and to the board on a quarterly basis.

Ultrasonic Aqueous Parts Cleaning in Auto Repair

Download the document.

In October 2020, PPRC conducted an EcoBiz certification visit with Autobahn Motorwerks (Autobahn). Among several best practices in place, EcoBiz learned of their replacement of a solvent parts washer with an ultrasonic system, utilizing an EPA Safer Choice all-purpose cleaner. PPRC discovered that these ultrasonic cleaners are commonly used by jewelry makers and laboratories, but are becoming popular for auto repair shops, due to excellent cleaning performance and avoidance of solvents. A 30 liter (30L) unit seems suitable for throughput typical of smaller shops (under 10 employees), and 100L may be a better size for larger auto shops.

During an EcoBiz certification at another auto shop in Oregon, PPRC found they were interested in ultrasonic cleaning as well, especially because of staff sensitivity to some solvents. They periodically used non-chlorinated aerosol cleaners for parts cleaning, and for larger-part cleaning jobs, would send out an entire part for cleaning. They purchased a 30L ultrasonic unit and are trialing two non-hazardous aqueous cleaners. Both shops are pleased with ultrasonic cleaning and eliminating solvents for parts washing.

Tips, best practices for use, brief success stories, and cost benefit analyses are presented below.

Unsnarling traffic jams is the newest way to lower emissions

Read the full story in Scientific American.

The Department of Energy is preparing to use the massive computing power of its national laboratories to tackle a daily scourge of American life: traffic jams.

The effort is aimed at more than just improving motorists’ moods. If it works, it could cut U.S. transportation fuel consumption up to 20% and reduce auto emissions.

A second goal is to recover as much as $100 billion in lost worker productivity by unsnarling rush hour traffic jams in U.S. cities over the next 10 years.
