KIT team designs low-cost photoreactor for efficient solar-driven synthesis

Green Car Congress

Researchers from the Karlsruhe Institute of Technology (KIT) and their Canadian partners have designed a low-cost photoreactor design for solar-driven synthesis. Until now, however, the technology has mainly been found in the laboratory because the costs of producing solar hydrogen were simply too high. Joule doi: 10.1016/j.joule.2023.05.006

NSF awards UCSD team $39M to improve integration of distributed energy resources into grid; EV batteries also

Green Car Congress

Solar panel output depends on the weather, for example, as do wind turbines. As a result, while the number and diversity of distributed energy resources on the power grid is rapidly expanding, the adoption of these resources for power-grid balancing is hindered by concerns about safety, reliability and cost.

Tesla adds ‘Charge on Excess Solar’ function in app to get clean range at home

Teslarati

Tesla is going to let owners of its electric vehicles charge their cars using excess solar energy that has accumulated throughout the day and can’t be stored in a Powerwall, coding in its smartphone app seems to reveal. “Set your charge limits and location and tell your vehicle when and where to charge only from excess solar.”

Survey of California plug-in vehicle owners highlights charging behavior

Green Car Congress

Californians own more than 12,000 plug-in electric vehicles (PEVs), roughly 35% of all plug-in vehicles in the United States. As of July 2012, approximately 1,000 new plug-in vehicles are being sold in the state every month. This is the largest plug-in electric vehicle owner survey ever taken in California. Source: CCSE.

Next 10 reports explore rapid changes to California grid driven by EVs, distributed energy resources and community choice aggregation

Green Car Congress

As the state adds more variable renewable energy to the grid, these resources—electric vehicles, distributed energy resources and community choice aggregators—represent a challenge to the traditional energy management system but also provide opportunities for us to manage a more efficient and cleaner grid.

Cemvita demonstrates “gold hydrogen” production in situ, sets up subsidiary

Green Car Congress

Cemvita defines Gold Hydrogen as the biological production of hydrogen in the subsurface through the consumption of trapped or abandoned resources. Traditional methods of producing hydrogen without greenhouse gas emissions (green hydrogen) include electrolysis powered by renewable sources such as wind, solar, or hydro. billion in 2020.
