ARPA-E talks advanced hybridization, carbon-neutral liquid fuels

In the race to place the automotive sector on a sustainable footing, the field is dominated by just two horses: battery-electricity and hydrogen fuel cells.  The economic implementation of BEVs is already well underway, with motor companies on track in 2017 to sell more than a million vehicles globally for the first time.  The economic implementation of FCVs is also in progress, albeit at a much earlier stage, and has the backing of major motor companies and public-sector agencies.  Given the huge leads enjoyed by electricity and hydrogen, ammonia is scarcely seen as a contending fuel.  Earlier this month, though, the U.S. Department of Energy’s ARPA-E unit published an interview with two of its program managers that has an intriguing implication: the race is far from over and ammonia may yet break to the front of the pack.

REFUEL Is Back on Track

The U.S. Department of Energy’s ARPA-E REFUEL Program, whose continued existence seemed to be in doubt two months ago, now appears to be back on track.  Invitations were sent a week ago for the ARPA-E REFUEL Program Kickoff, an event that was originally scheduled for April 25 and 26 in Houston.  It is now scheduled to take place in Denver on August 16, 17, and 18.  Attendance will be by invitation only.

The new generation of fuel cells: fast, furious, and flexible

At ARPA-E's recent Energy Innovation Summit in Washington, DC, Program Director Grigorii Soloveichik presented his vision for the future of transportation: hybrid electric vehicles that combine the advantages of both plug-in battery and fuel cell technologies. This "optimal solution" will require a new generation of fuel cell that is "fast, furious, and flexible." Fast, in terms of start-up / shut-down time. Furious, in terms of energy density. And flexible, in terms of fuel choice - specifically sustainable liquid fuels, like ammonia.

Carbon Pricing and the Economics of Green Ammonia

The United States Senate is expected to open confirmation hearings for Secretary of State nominee Rex Tillerson on January 11. Tillerson, newly retired from Exxon Mobil, became the chief executive officer of that company in 2006. He has attracted many labels since his nomination was announced, but “climate denier” is not among them.

ARPA-E’s “transformative” ammonia synthesis technologies

The US Department of Energy's Advanced Research Project Agency (ARPA-E) is funding projects with a view to commercializing low- and zero-carbon ammonia synthesis technologies. Grigorii Soloveichik, ARPA-E Program Director, described the aims and challenges of his agency's initiative and introduced the technologies currently in development in his keynote presentation at the recent NH3 Fuel Conference, in September 2016.
