A dynamic model of food and clean energy [PDF]
Journal of Economic Dynamics and Control, 2008 In the midwestern United States, ethanol produced from corn is mixed with gasoline to meet clean air standards. Allocating land to produce clean fuel means taking away land from farming. We examine the use of a scarce fossil fuel that causes pollution but may be substituted by a clean fuel produced from land.

Clean energy and the hydrogen economy [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2017 In recent years, new-found interest in the hydrogen economy from both industry and academia has helped to shed light on its potential. Hydrogen can enable an energy revolution by providing much needed flexibility in renewable energy systems. As a clean energy carrier, hydrogen offers a range of benefits for simultaneously decarbonizing the transport ...
