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

Green Car Congress

While there are many effective solutions for daily energy storage, the most common being batteries, a cost-effective long-term solution is still lacking. The investment costs of UGES are about 1 to 10 US$/kWh and power capacity costs of 2.000 US$/kW. An open-access paper on the work is published in the journal Energies.

Volvo Cars switches to biodiesel for ocean freight; cutting fossil CO2 emissions by 84%

Green Car Congress

The reduction is equivalent to the CO 2 emissions of a full truck driving around the equator about 1,200 times. The fuel used is Fatty Acid Methyl Esters (FAME) (biodiesel) and is based on renewable and sustainable sources, mainly waste cooking oil. No feedstock related to palm oil or palm oil production is used.

Mixing crumb rubber from recycled tires with bitumen halves rate of sun damage to roads

Green Car Congress

New research has found that mixing rubber from used tires with bitumen can halve the rate of sun damage to roads. Incorporating recycled rubber not only offers sun protection but provides a promising sustainable solution to Australia’s used-tire crisis, with used tires in Australia subject to an export ban since December 2020.
