I made ten predictions in January 2014 about Smart Grid and Smart City trends and changes that will occur between 2014 and 2020. Here is an update on the final five predictions. The first five were reviewed last week. You can review the full predictions here and here, and judge for yourself the quality of my crystal ball.
6. Debates about the future of the social compact for electricity services and the socialization of electricity costs continue. The Reforming Energy Vision initiative includes the objective to “enable and facilitate” new business models for utilities, customers, and energy service companies. This is just the first state activity that will generate significant discussion about how to equitably balance distribution grid investments that accommodate and integrate more distributed energy resources (DER). Since it will take time to implement and then measure results from new business models, this debate is sure to continue for the next decade.
7. EVs advance to 10% of the US car market. The current electric vehicle (EV) penetration in 2013 was just a bit over .5%. The falling costs of gasoline are putting additional pressure on EV manufacturers to reduce prices of zero emission vehicles to increase consumer adoption. However, utilities are now taking a more active role, as Edison Electric Institute members will start investing up to $50 million annually in EV service trucks and charging stations for consumers. The Department of Defense (DoD) is conducting pilots for vehicle to grid or V2G applications. Their first smart charging demonstration are exploring V2G performance, and they will also examine re-purposing used EV batteries for fixed energy storage.
8. Resiliency measures also become part of the definition of a smart building. There are a number of federal, state, and non-governmental initiatives that address resiliency, and some critical infrastructure definitions include selected buildings. The National Institute of Standards and Technology (NIST) is developing standards guidance for community disaster resilience, but this is focused on building materials and codes. Microgrids, DER and Zero Net energy codes and technologies can bridge the gap in existing resiliency initiatives for buildings. Microgrids are already in production as resources to maintain power to critical infrastructure during emergencies – one of the goals of the Borrego Springs microgrid.
9. Nanotechnologies help propel solar harvesting efficiencies past the 50% mark, and by 2020 research scientists are aiming for 75% harvest efficiencies. The number of patents filed for innovations in nanotechnology using graphene have tripled in the past 10 years. The research pipeline contains single molecule thick sheets of graphene and molybdenum that can potentially provide 1000 times more power per weight unit of material than current commercially available solar cells. The fabrication of flexible solar panels is on the horizon, which can be wrapped around curved or uneven surfaces or reduced in scale, expand the possibilities for where solar can be deployed.
10. There’s sufficient electricity production from renewable energy sources that we no longer talk about “renewables.” American grid-connected wind turbines have a combined capacity of 60,000 MW, projected to double by 2020. Solar is enjoying explosive growth. Energy storage solutions will “firm up” the intermittency of wind and solar and thus eliminate the last objections to reliance on renewables. It will just be a cheap and clean source of electricity without the price volatility of fossil fuels.
These final five predictions are well on their way to realization too, although the prediction about nanotechnology advances is admittedly a stretch goal. You’ll note that energy storage has a significant influence on the advancement of some of these predictions. We’ll keep tracking these predictions and bring you periodic updates.
