Agrivoltaic systems have the potential to meet energy demands of electric vehicles in rural Oregon, US

Abstract

Electrification of the transportation industry is necessary; however, range anxiety has proven to be a major hindrance to individuals adopting electric vehicles (EVs). Agrivoltaic systems (AVS) can facilitate the transition to EVs by powering EV charging stations along major rural roadways, increasing their density and mitigating range anxiety. Here we conduct case study analyses of future EV power needs for Oregon, USA, and identify 174 kha of AVS viable agricultural land outside urban boundaries that is south facing and does not have prohibitive attributes (designated wetland, forested land, or otherwise protected lands). 86% highway access points have sufficient available land to supply EV charging stations with AVS. These AVS installations would occupy less than 3% (5 kha) of the identified available land area. Installing EV charging stations at these 86% highway access points would yield 231 EV charging stations with a median range of 5.9 km (3.6 mi), a distance comparable to driver expectations, suggesting that this approach would serve to mitigate range anxiety. AVS powered rural charging stations in Oregon could support the equivalent of 673,915 electric vehicles yr−1, reducing carbon emissions due to vehicle use in OR by 3.1 mil MTCO2 yr−1, or 21%.

Application of Internet of Things to Agriculture—The LQ-FieldPheno Platform: A High-Throughput Platform for Obtaining Crop Phenotypes in Field

“…Solar energy might be a good option, and there are already many successful examples of greenhouse solar farms. The solar production system has been widely presented in a number of related studies [ 41 – 43 ]. It could be considered for integration into plant phenotyping platforms to achieve energy savings.…”

“…The APV is becoming popular in many countries, such as the USA, Japan, South Korea, China, France, and India [ 8 , 9 ]. For example, APV was found potential as electric vehicle charging station in rural Oregon, USA [ 10 ]. It was also reported that “ APV's dual function of agricultural yield protection while simultaneously generating solar power increases the economic output per area and enhances farmers' resilience against the impacts of global warming by securing and diversifying their sources of income ” [ 11 ].…”
