"Developing Sustainable Pathways to Fuels and Chemicals"
Tom Jaramillo, associate professor of chemical engineering and of photon science, Stanford University
Energy Seminar - September 21, 2015
Nearly all the fuels and chemicals produced and consumed today are derived from fossil resources. This talk will describe recent efforts to develop new, renewable pathways to produce the same kinds of fuels and chemicals that our society relies on, though in a sustainable manner. In particular, the talk will focus on two areas of sustainable technology: (1) Solar-based processes for the renewable production of H2 from water, and (2) CO2 conversion to produce carbon-based fuels and chemicals. Keys to improving these technologies for widespread commercialization involve the development of higher performance semiconductors, interfaces, and catalyst materials for high efficiency, stability, and selectivity for targeted products. This talk will describe challenges in the field and our means to address them through our research efforts to engineer improved materials and devices.

Excellent presentation. This guy realizes where it all has to go. Make fuels, don't store it in a battery. New Engine Type (NET) tech captures the CO2 on the car with a combined cycle. The CO2 is off loaded to house and then turned into Ethanol via solar THERMALS+NET. CO2 is recycled. The efficiency of NET is 60% (primary cycle) at 100% torque (acceleration), and 75% below 50% torque (cruise, with combined cycle). NET has brake recovery of 75%. NET is a COP 4 heat pump. EVs are not the future. We need fuels... Fuel making with NET solar thermal can be 3 cents/kwh. A 100% RE grid will be 60 cents/kwh. NET is 1.5x better MPGe than an EV. Battery + 100% RE grid EV is 600 gCO2/kwh. NET is 3 gCO2/kwh for fuel, no drive battery. 200:1 in CO2.
Good info in general
NET on 5 kg H2 (5 gallons gasoline) would go, in miles: 150 x 5 = 750 HWY 240 x 5 = 1200 City 200 x 5 =1000 combined. Makes little sense to make EVs vs NET combustion tech with combined cycle. We don't have the materials for batteries, nor old ICE combustion. NET can replace all engines that were combustion except jet engines. NET can eliminate the need for airlines, which leaves only jet fighters and some military tasks needing turbines. This will all take a few generations. No more EVs, only NET. Start with Ethanol/methanol and phase out oil for transit.
