Reducing (and eventually reversing) the increase in greenhouse gases (GHGs) in the atmosphere due to human activities, and thus reducing the extent and severity of anthropogenic climate change, is one of the great challenges facing humanity. While most of the man-caused increase in GHGs has been due to fossil fuel use, land use (including agriculture) currently accounts for about 25% of total GHG emissions and thus there is a need to include emission reductions from the land use sector as part of an effective climate change mitigation strategy.

During the ALPHA program, ARPA-E commissioned a report on the fusion intellectual-property (IP) landscape.  Some key takeaways from the report are:

  • Magnetic and inertial confinement dominate existing IP landscape
  • Magneto-inertial or other approaches are a ripe area for creating new IP
  • Over 50% of fusion IP is expired, primarily due to non-payment of fees
  • Be judicious in timing of filing, given the 20-year protection time frame.

Investments in solar photovoltaics and wind turbines are soaring as costs fall and governments and companies seek to reduce greenhouse-gas emissions. But fluctuating power from the wind and sun threatens to destabilize electricity grids. As more intermittent sources are connected, the power surges and crashes. This increases variability in voltage, in power and in the frequency of alternating current.

ABSTRACT: A variety of inherently robust energy storage technologies hold the promise to increase the range and decrease the cost of electric vehicles (EVs). These technologies help diversify approaches to EV energy storage, complementing current focus on high specific energy lithium-ion batteries.
