Convert Oil Wells to Solve the Solar Storage Problem

Cars That Think

Solar batteries work as a short-term solution, but not when it comes to long-term storage or to power, say, an entire city. A possible answer, though, might lie in oil wells. Solar energy and oil wells might sound like an odd combination, but the principle is similar to how geothermal energy would be harnessed.

Additional $47M to 7 ARPA-E SCALEUP projects; $27M to 3 advanced battery projects for EVs and electric aviation

Green Car Congress

The goal of the program is to translate the performance achieved at the lab- and bench-scale by previously funded ARPA-E technologies to commercial viability, supporting promising energy technologies that require scaling-up or pre-pilot projects to enable a path to market and ultimately lead to realized commercial impact.

Thermal Solar Goes Where PVs Can’t

Cars That Think

In recent years, however, CSP development stalled amid the rapidly falling cost of solar PV. Even so, solar-thermal developments continue to unfurl across the planet's sunniest expanses, driven by the growing demand for energy storage and cleaner heat sources. Massive solar-thermal arrays require steep upfront investment.

NRC report concludes US LDVs could cut oil consumption and GHGs by 80% by 2050; reliance on plug-ins, biofuels and hydrogen; strong policies mandatory

Green Car Congress

The committee supports consistent R&D to advance technology development and to reduce the costs of alternative fuels and vehicles. Well before 2050 the cost of FCEVs could actually be lower than the cost of an equivalent ICEV, and operating costs should also be lower. —Douglas M. l/100 km) for the midrange case.

DNV GL paper suggests near-term success for LNG in shipping; alternative fuel mix to diversify over time

Green Car Congress

While LNG is expected to be an early success, the picture becomes more diversified over time, as more than 20% of shipping could adopt hybrid propulsion solutions featuring batteries or other energy storage technologies, according to the paper. Engine concepts include gas-only engines; dual fuel 4-stroke; and 2-stoke.
