DOE's Sarkar“When we look at regulatory measures going forward, we see a lot of opportunities in these sectors,” according to Kitowski. “Lifecycle emissions of electric vehicles are lower than their counterparts of diesel and natural gas.”
He added that this year, CARB has provided over $4 billion in incentives in clean technology over the last four years.
DOE is using a three-tiered approach when looking at ZEV technology: fuel diversification, vehicle efficiency energy, and mobility systems. According to Sarkar, ZEV drivers include:
- Falling technology costs – take an engine today, you can make it more efficient, but it costs more money.
- Modern grid – bringing a lot more clean electrons on from renewable resources and more ways to connect to the grid.
- Increasing urbanization – more and more people moving into cities. More congestion and higher need to address the issues related to that.
- Changing consumer preferences
- Rise of Connected and Automated Vehicles
- Emergence of New Mobility Models
- Global Imperatives
“The primary source for ZEVs today is getting clean electrons,” Sarkar said. “We’re experiencing a revolution now in clean energy. We are seeing a repeating trend happening.”
He noted that though the cost of batteries has been falling – from more than $1,000/kWh down to $250/kWh today – that even a goal of reaching $125/kWh by 2022 isn’t good enough due to low gas prices. Yet Sarkar explained the cost will have to go down to at least an $80/kWh battery, and that it will take another decade to get there.
“I think when most people think about the lifecycle they think about battery replacements,” he added. “The number of brake repairs [for ZEVs] are dramatically lower. I think the lifecycle will be equivalent or better than a combustion engine equivalent because there will be less maintenance. I think the risk is low, which is what I think most people think about when trying to compare the two.”
