IIASA-led study proposes Underground Gravity Energy Storage as long-term energy storage solution for renewables

Green Car Congress

UGES generates electricity when the price is high by lowering sand into an underground mine and converting the potential energy of the sand into electricity via regenerative braking and then lifting the sand from the mine to an upper reservoir using electric motors to store energy when electricity is cheap.

Looking to get in a hybrid for cheap? Used Toyota Prius 1.5 HSD 2004-2009 Review

Green Car Congress

I knew I wanted something for her that was cheap to maintain, had a reliable automatic transmission, came with cruise control, AC. The cost of that usually starting just below $1,000 or changing the faulty modules (28 modules in a pack) individually that is much cheaper. It is something very cheap to fix and to inspect.

Lux Research: cost of electrofuels remains far from viable

Green Car Congress

Production costs per barrel of oil equivalent. The cost of electrofuels—fuels produced by catalyst-based systems for light capture, water electrolysis, and catalytic conversion of carbon dioxide and hydrogen to liquid fuels—remains far away from viable, according to a new analysis by Lux Research.

Univ of Washington team working to make poplar coppice viable cheap, high-volume biofuel feedstock

Green Car Congress

The UW team is the first to try converting the entire young tree—leaves, bark and stems—into bio oil and ethanol using two separate processes. Our research proved that poplar coppice can be a good option to meet the cheap, high-volume criteria of biofuel feedstock.

KU Leuven team creates solar panel that produces hydrogen from moisture in air

Green Car Congress

A traditional solar panel converts between 18 to 20% of the solar energy into electricity. m² that converts 15% of the sunlight straight into hydrogen gas. The hydrogen gas produced in the summer will be stored and converted into electricity and heat in the winter. —Johan Martens.

A*STAR team combines fungal culture and acid hydrolyses for cost-effective production of fermentable sugars from palm oil waste

Green Car Congress

Researchers from A*STAR in Singapore have developed a fungal culture for use in a cheap and efficient method to transform waste oil palm material into biofuels and environmentally friendly plastics. glucosidase can be added to the commercial preparations, which then ramps up the cost of converting oil palm biomass into biofuel and bioplastic.

BNEF: steel industry set to pivot to hydrogen in green push; additional $278B for clean capacity and retrofits

Green Car Congress

The report “Decarbonizing Steel: A Net-Zero Pathway” outlines the path to making profitable, low-emissions steel and describes how a combination of falling hydrogen costs, cheap clean power, and increased recycling could reduce emissions to net zero, even while total output increases.
