Testing Heats Up at Sandia’s Solar Tower

Researchers at Sandia National Laboratories are working to lower the cost of solar energy systems and improve efficiencies in a big way, thanks to a system of small particles. This month, engineers lifted Sandia’s continuously recirculating falling particle receiver to the top of the tower at theNational Solar Thermal Test Facility,marking the start of first-of-its-kind testing that will continue through 2015. The Sandia-developed falling particle receiver works by dropping sand-like ceramic particles through a beam of concentrated sunlight, capturing and storing the heated particles in an insulated tank. The technology can capture and store heat at high temperatures without breaking down, unlike conventional molten salt systems.

Battery Second Use Offsets Electric Vehicle Expenses, Improves Grid Stability

Plug-in electric vehicles (PEVs) have the potential to dramatically drive down consumption of carbon-based fuels and reduce greenhouse gas emissions, but the relatively high price of these vehicles — due in large part to the cost of batteries — has presented a major impediment to widespread market penetration. Researchers at the Energy Department’s National Renewable Energy Laboratory (NREL) are playing a crucial role in identifying battery second use (B2U) strategies capable of offsetting vehicle expenses while improving utility grid stability.

Listen Up: Charging Your Electric Vehicle

Electric vehicles are great: they’re affordable, great for the environment and low maintenance. And where electric rates are low — or if you have rooftop solar power — EVs are cheaper to drive per mile than gas-powered cars. But you have to think about how you will charge your EV: there are only a few thousand public charging locations in the U.S. compared to 100,000 gas stations.

Rain or Shine, Students Keep Their Solar Race Cars Going with Energy Storage

Teegan and Kira Cordova love the original Star Trek TV series. That much is obvious. The eighth-grade twins from Ken Caryl Middle School in Littleton are wearing the uniform tunics from the 1960s show — Teegan’s in red and Kira’s in blue. The model electric car they’re racing in the 25th Annual Junior Solar Sprint and Lithium Ion Battery car competitions carries the designation NCC-1701, the same identifier emblazoned across the hull of the USS Enterprise — which fits perfectly with their car’s name: “Starship Enterprise.”

Renewable Energy Is Beginning To Power Africa

According to the International Energy Agency, sub-Saharan Africa will require more than $300 billion in investment to achieve universal electricity access by 2030.

Committing more than $7 billion in U.S. government support and attracting nearly three-times that in private sector funding, Power Africa, which launched in October 2013, marks a milestone for President Obama with regard to action on climate change and clean energy, not to mention foreign relations and international development. The initiative gives the U.S. a leadership role in addressing a range of critical regional and global issues – eradicating poverty, improving health and gender equality, opening up economic opportunity and conserving ecosystems and natural resources as well as promoting clean, renewable energy. In this regard the program dovetails nicely with the U.N.’s expiring Millennium Development Goals (MDGs) and its new strategic Sustainable Development Goals (SDGs), as well as Secretary General Ban Ki-moon’s Sustainable Energy for All initiative.
