Priority of resolution to drive NGV deployment
Need to ensure engine efficiency growth, and remain compatible with new auxiliary technology such as heat recovery
Expand range of engine types and sizes to increase user compatibility
Need to increase diesel substitution and robustness
Increase purpose-design NGV vehicles with optimised perf/packaging
Important to support for early roll out, but need to standardise and cost reduceIncrease storgae capacity/density for range, and reduce storage pressure requirements
Reduce cost, increase production scale. Improve fuel level sensing
On-site compression is widespread. Standards and cost reduction required. Technology for small fleet/ home refueling
Small scale liquefaction plants will allow wider, economic LNG site deployment.Digesters & biogas upgraders are commercially available & widely used in Europe/China
Reduce site costs to improve infrastructure economics
Widespread LNG storage will require low-cost modular tanksCryogenic pumps not as reliable as CNG/Gasoline. Further dev’t of automated unmanned pumps.
Home and small fleet pumps are reasonably mature but not economic
Peak shavers/LNG Terminals
Better utilisation of existing LNG production
Fuel quality consistencyStandards required for RNG. Auto-sensing & correction will increase product robustness

Natural Gas points for discussion
• What improvements may be expected in diesel and gasoline engine efficiency/ fuel economy over the next 40 years?
• What levels of system cost reduction- engines and components such as cryogenic pumps and tanks- may be expected over next 40 years for natural gas engine systems, some of which are just now being deployed in demonstration level volumes?
• How can the development of technologies for the commercialization of Renewable Natural Gas/Biomethane be accelerated, so as to capitalize on the 80-100 percent reduction in GHG emissions made possible by RNG, compared to conventional oil and diesel transport use?

Biofuels points for discussion
• What is a realistic time frame and cost to advance and deploy advanced technologies for basic technologies like energy that require large amounts of infrastructure?
• Are there any current energy based technologies with leapfrog potential and how will such technologies overcome the huge inertia current technologies have?
• Will expanding our energy supply be the biggest driver in the future or CO2
abatement?

Electric points for discussion (1 of 2)
• The basic premise of our "barriers" chart is that with current Li-Ion-based batteries, there is not a pathway to achieve a larger-format (larger than midsize vehicle, e.g. Explorer), longer-range (e.g. 200 miles) EV at a competitive price – that some other chemistry will need to be discovered and/or developed. Based on this premise, we evaluated three representative vehicles that were all mid-size or smaller and had different operating modes, but that could reach cost competitiveness and market acceptance.
1. Do you agree with this premise?2. Is this vehicle classification useful?
• For Battery costs in the PHEV-10 case, we assigned a rating of "Green" by 2020. This is based on the anticipation that the USABC goal of $500/kWh can be achieved no later than 2020. For the PHEV-40 and BEV-100 case, cost is rated at "Red” for the next 2 decades.
1. Does the panel concur with our conclusion that battery cost competitiveness for PHEV40 and EV100 applications by 2020 is high risk and a significant barrier to mass adoption?
2. Does the panel agree with our conclusion that the pathway to bring battery costs for PHEV40 and EV100 applications to cost parity before 2035 is achievable with Li-Ion batteries, given investment and time?
3. The literature suggests that achieving an energy density of 300 Wh/kg at the cell level (reducing pack weight to approx. 80 Kg (~180 lbs) in the 2020-2035 timeframe is achievable. Is this assumption reasonable? If so, can it be achieved at a competitive cost?

Electric points for discussion (2 of 2)
• In a review of various battery cost studies, we found wide disparity in both current and projected costs for Li-Ion batteries for EVs. When reviewing those studies that used a “bottom-up” costing methodology, the range of costs was much smaller. How do you evaluate a battery study to assess credibility? Which studies in particular do you find credible?
• For both Li-ion and “beyond Li-Ion” batteries1. What will be the most important advances be in the next 10-20 years?2. Which areas specifically need the most R&D investment in the next 10 years?3. How can we determine an appropriate R&D investment level that does not cross over into
diminishing returns?

Hydrogen points for discussion
• In your view, what are the key significant challenges and barriers for the success of hydrogen mobility in addition to the ones we have identified?
• What criteria needs to be met for any new fuel or vehicle propulsion system to achieve significant market introduction?
• Our subgroup is currently prioritizing fuel cell vehicles over hydrogen internal
combustion engine vehicles. What do you see the scope of the application for hydrogen as a transportation fuel and the order of market entry. – Do you agree with prioritizing fuel cells vehicles over hydrogen ICEs– Which vehicle segments would you prioritize over others (e.g. long haul
trucking over busses over light duty vehicles, etc…)?
