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

Green Car Congress

Renewable energy sources are central to the energy transition toward a more sustainable future. However, because sunshine and wind are inherently variable and inconsistent, finding ways to store energy in an accessible and efficient way is crucial. An open-access paper on the work is published in the journal Energies.

Researchers use quantum computing method to optimize molecular photoswitches for solar energy harvesting

Green Car Congress

Molecular photoswitches that can both convert and store energy could be used to make solar energy harvesting more efficient. The procedure was based on a dataset of more than 400,000 molecules, which the researchers screened to find the optimum molecular structure for solar energy storage materials.

Bombardier (now Alstom) to convert AGC hybrid trains to full battery power

Green Car Congress

To help France meet its sustainability targets, Bombardier will now convert AGC hybrid trains to full battery power. The idea is to convert dual-mode (catenary and diesel-powered) high capacity self-propelled trains to dual-mode battery-powered AGCs.

Researchers store hydrogen fuel in salts

Green Car Congress

Researchers in Germany have developed a method to store and release highly pure hydrogen by the interconversion of readily available (bi)carbonate and formate salts in the presence of naturally occurring ?-amino amino acids. An open-access paper on their work is published in ACS Central Science.

Siemens Energy, FFI and GeoPura developing prototype ammonia cracker to produce hydrogen

Green Car Congress

A Siemens Energy-led consortium has begun work in Newcastle, UK on a new £3.5 It selectively filters the hydrogen while blocking other gases, allowing it to be used as a fuel and converted as needed, at the time of re-fueling. Siemens Energy has proven experience of innovation with ammonia. million (US$4.24 million (US$1.8-million)

New electrocatalyst converts CO2 into ethanol, acetone, and n-butanol with high efficiency

Green Car Congress

The electrocatalytic conversion of CO 2 using renewable energy could establish a climate-neutral, artificial carbon cycle. Excess energy produced by photovoltaics and wind energy could be stored through the electrocatalytic production of fuels from CO 2. These could then be burned as needed. and Xiong, Y.
