CPUC proposes revising Net Energy Metering rules to push customers to install storage with rooftop solar

Green Car Congress

For more than 20 years, California has aggressively supported the rooftop solar market through its Net Energy Metering (NEM) program in Pacific Gas and Electric Company (PG&E), Southern California Edison (SCE), and San Diego Gas & Electric Company (SDG&E) territories. NEM has enabled 1.3 An independent third-party evaluation of NEM 2.0

Stanford team sets record for solar-to-hydrogen efficiency of solar water splitting: >30%

Green Car Congress

Researchers at Stanford University have demonstrated solar water splitting by photovoltaic-electrolysis with a solar-to-hydrogen (STH) efficiency of more than 30%—a new record. The results, the researchers said, demonstrate the potential of photovoltaic-electrolysis systems for cost-effective solar energy storage.

Cummins invests $24M in flow battery leader VoltStorage

Green Car Congress

Headquartered in Munich, VoltStorage was founded in 2016 by Jakob Bitner, Michael Peither and Felix Kiefl. In addition, the international research and development team is working on the low-cost iron-salt battery, the properties of which make it particularly suitable for ensuring base load capability for wind and solar farms.

Nissan cuts CO2 emissions from global corporate activities by 2% in 2013; tracking to 20% by 2016 vs. 2005

Green Car Congress

cut in CO 2 during the year puts the company on track to achieve its goal of a 20% reduction by fiscal year 2016, compared to 2005. Nissan set the target in its mid-term environmental action plan, the Nissan Green Program 2016 (NGP2016). Energy procurement is being shifted toward more sustainable sources, like biomass and solar power.

Bloomberg NEF forecasts falling battery prices enabling surge in wind and solar to 50% of global generation by 2050

Green Car Congress

The arrival of cheap battery storage will mean that it becomes increasingly possible to finesse the delivery of electricity from wind and solar, so that these technologies can help meet demand even when the wind isn’t blowing and the sun isn’t shining. trillion of that going to wind and solar and a further $1.5 NEO 2018 sees $11.5
