Vehicle-To-Grid

1. Problem: Unidirectional Grid-To-Vehicle Charging   

Fossil fuels from internal combustion engine vehicles as well as electricity generation from coal and natural gas emit greenhouse gases that cause global warming. To decarbonize transportation and electricity, renewable energy sources are needed. Since the sun and wind are not always present, energy must be used immediately or stored. Upgrading residential and commercial buildings with battery storage is expensive and time-consuming. The batteries inside electric vehicles (EVs) provide an opportunity for power without resorting to fossil fuel sources. However, traditional grid-to-vehicle (G2V) charging stations are unidirectional. 


2. Solution: Bidirectional Vehicle-To-Grid Charging

Vehicle-to-grid (V2G) technology provides bidirectional charging for plug-in EVs, battery EVs, plug-in hybrids, and hydrogen fuel cell EVs. V2G provides drivers demand response services with the ability to send electricity into an EV battery as well as sell this energy back to the grid. EV batteries are the most cost-efficient energy storage solution since no new hardware investment is needed. With broad deployment, V2G could improve grid stability and reduce stress to meet peak demand from renewable sources. This will ultimately reduce carbon emissions on the journey to net-zero. Key features include:

— V2G EV charging equipment enables the flexible two way flow of electricity. 
— EV drivers select charging or selling electricity to the grid with a mobile application. 
— Drivers set minimum charge levels, plus view charging updates and history. 
— The charge management system enables and monitors V2G charging features. 
— Drivers save money via credits to reduce the total cost of ownership in participating markets.
— Using EVs for grid storage may impact battery life based on a finite number of charges.

Vehicle-to-everything (V2X) expands use cases to include vehicle-to-home (V2H), vehicle-to-building (V2B) and vehicle-to-grid (V2G). The V2X ecosystem at scale can reduce the need for new power plants by tapping into EV batteries as distributed energy sources.


3. Stakeholders

The stakeholders in the V2G ecosystem include: 

— Charging Station Hardware Manufacturers: Dcbel and Coritech Services manufacture and sell residential fast chargers with V2G features.
— Charging Software Integrators: Virta provides V2G charging integration services for businesses. The mobile app allows an EV battery to remain 70-90% charged. 
— Car Manufacturers: Nissan is the only major manufacturer making V2G compatible cars with the Leaf and e-NV200. Other manufacturers are conducting V2G research and development. 
— Consumers: Drivers must buy EVs with V2G charging capabilities and enable these features. 
— Real Estate: Public and private site owners must approve V2G charging deployment. 
— Utilities: EDF is a Britain utility company that provides V2G charging energy bill savings. Other utility companies globally must develop and implement V2G programs.
— Policymakers: V2G incentives must be developed to spur adoption by market participants. 


4. Implementation

Significant market development is required before V2G can be deployed at scale to meet peak energy demand. Key challenges for V2G include:

1. The adoption of V2G standards by the majority of car manufacturers for future car models.
2. Utility network upgrade costs and standards for widespread bidirectional energy distribution. 
3. Policies that incentivize V2G public private partnerships. 

For car and utility companies that are currently V2G ready, the implementation steps include: 

1. Residential or business customers confirm V2G site feasibility with the utility company. 
2. Customers complete any utility grid interconnection requirements. 
3. Once approved, customers purchase and install a V2G ready EV charging station.
4. Customers signup for a V2G digital service accessed by mobile app and dashboard. 
5. Customers receive credit for energy sold back to the grid.

Advanced Metering Infrastructure (AMI)

1. Problem: Outdated Metering Infrastructure 

The electricity sector is approximately 25% of U.S. annual greenhouse gas emissions. Outdated energy infrastructure generates damaging environmental impacts with higher energy costs. Residential and commercial customers lack visibility of their energy consumption. Antiquated systems provide inaccurate meter readings that impact billing and generate operational and energy inefficiencies. As electric vehicle adoption increases alongside distributed energy generation sources, new measurement infrastructure is needed to prevent the grid from being overloaded. Utilities play a critical role in decarbonization yet face many challenges. 


2. Solution: Advanced Metering Infrastructure (AMI) 

Advanced metering infrastructure (AMI) enables utilities to gain visibility of energy usage to make more informed decisions and meet customer demand. AMI enables utilities to predict outage risk and respond faster. AMI also provides customers more control over electricity consumption with new tools and techniques. Features include:

— Near real-time smart grid predictive management of energy supply and demand. 
— Edge computing over 5G networks to provide scalable IoT cloud integration. 
— Advanced streaming analytics with AI that collects and reacts to energy data. 
— Energy insights surfaced on a dashboard to inform data-driven decisions. 
— Platform to trade electricity among customers and provide energy services.

Smart Meters 

Smart meters are electronic devices that measure energy use with data captured in 15-minute intervals. This data is securely sent to portals that can be accessed by customers and utilities. As smart meters are widely adopted, utilities can provide customers energy at the lowest cost and lowest environmental impact. ConEdison is installing 5 million smart meters over the next year. 

3. Stakeholders

Key constituents in the AMI and smart meter ecosystem include:

— Utilities: ConEdison in New York, PG&E in California, and Oncor in Texas are examples of utility companies that provide AMI solutions and smart meters to customers.  
— Technology Providers: Companies such as IBM provide AMI cloud services and Siemens develop smart meters used by utility companies. 
— Commercial and Complex Billing Customers: These customers gain insights on cost and usage trends. This includes tracking consumption to uncover energy efficiency opportunities. 
— Residential Customers: These customers track near real-time energy usage with comparison to similar homes and saving tips.
— Electric Vehicle Charging Companies: Charging stations integrate AMI and smart meters to collect and share energy consumption data with utilities.
— Policymakers: Federal and State politicians impact the financing of energy budgets and the rollout of programs that promote AMI and smart meters. 


4. Implementation

Once a residential, commercial, or complex billing customer decides to get a smart meter, the following steps are taken:

1. The customer contacts the utility company to request smart meter installation availability.  
2. Once eligibility is confirmed, an approved vendor completes the installation on location. 
3. Approximately 2 weeks after installation, customers access tools on their account dashboard. 
4. Near real-time usage, comparison, and analysis data surface energy efficiency opportunities.

PipeGuard: Water pipe leak detection robot.

1) Sustainability problem: Detecting leaks in the aging water infrastructure posses financial and infrastructure problems to the city. Area: Water

  • Most city’s water distribution systems lose an average of 20 percent of their supply because of leaks.
  • These leaks not only make shortages worse but also can cause serious structural damage to buildings and roads by undermining foundations.
  • Leak detection systems currently in use are expensive and slow to operate, and don’t work well in systems that use wood, clay, or plastic pipes, which account for the majority of systems in the developing world.

2)  Technology

  • The PipeGuard is a small, rubbery robotic device that looks something like an oversized badminton birdie. The device can be inserted into the water system through any fire hydrant.
  • It then moves passively with the flow, logging its position as it goes. It detects even small variations in pressure by sensing the pull at the edges of its soft rubber skirt, which fills the diameter of of the pipe.
  • The device is then retrieved using a net through another hydrant, and its data is uploaded. No digging is required, and there is no need for any interruption of the water service. In addition to the passive device that is pushed by the water flow, the team also produced an active version that can control its motion.

“The process starts with sewage water that is filtered to extract larger particles, bacteria and viruses. Then, through reverse osmosis, membranes refine the water again, sifting out further contaminants and getting rid of any disease-causing agents. Finally, ultraviolet disinfection is used to make sure the water is truly pure and ready to use. The final product even exceeds the FAO’s safety standards.”
