Stanford District Energy System cuts GHG emissions 68 percent and fossil fuel 65 percent #BT2443

1-stanford

1) Sustainability area(s).

Cities consuming over 70 percent of global energy use and, producing 40 to 50 percent of greenhouse gas emissions worldwide. In some cities, heating and cooling can account for up to half of local energy consumption. Any solution for the climate and energy transition must address sustainable urban heating and cooling, as well as electricity. One of the least-cost and most efficient solutions for reducing emissions and primary energy demand is the development of modern (climate-resilient and low-carbon) district energy in cities.

2) Sustainability Technology:

The combined new system – Stanford Energy System Innovations (SESI) – makes Stanford one of the most energy-efficient research universities in the world.

-SEIS represents a transformation of university energy supply from a 100% fossil-fuel-based combined heat and power plant to grid-sourced electricity and a more efficient electric heat recovery system.

-High-efficiency new-building standards and improvements to existing buildings, a high-voltage substation, state-of-the-art solar arrays and a new central energy facility (CUP) that incorporates the largest heat-recovery chillers ever installed in the U.S

-SESI uses a combination of heat recovery, low-temperature hot water distribution, and thermal energy storage to reduce campus greenhouse gas emissions by 68% and drinking water use by 15%

-Technology roadmap for building heating and cooling

Blockchain Peer Peer Energy Microgrid

Infrastructure Problem: Renewable Energy From microgrid can be wasted due to inefficient data and demand

Solar panel owners get a small return for feeding excess power from their roof back into the grid, which power companies then on-sell at a much higher price.  Peer-to-peer trading overhauls the system by opening up the market to allow households to buy and sell solar energy without a power company, trading their energy for more than the feed-in tariff while still undercutting power providers for buyers.

Infrastructure Technology:

Power Ledger has developed software which reads the outputs of electricity meters and can therefore measure the amount of energy that is consumed or generated. Power Ledger is a blockchain-based peer-to-peer energy trading platform enabling consumers and businesses to sell their surplus solar power to their neighbours without a middleman.

Those two pieces of information are then recorded on the Blockchain and used to move energy from one person to another via a unit called ‘Sparkz’, which is a digital representation of energy. The buyer receives the energy and the seller banks payment for the electricity almost simultaneously

The Power Ledger system tracks the generation and consumption of all trading participants and settles energy trades on pre-determined terms and conditions in near real time. A user simply receives a registration email from their Application Host, they click on a link which takes them to the Power Ledger platform where they create a userid and password. That’s it, once logged in they can see their electricity usage and all their P2P trading transaction details.

Will Drones End Society’s Range Anxiety?

 

The Problem

Category: Energy/Health

An electric vehicle owner in a rural area often fears that his car battery will die before he reaches an electric charging station.  Even urban EV owners fear their batteries will deplete in a major traffic jam.  Stationary charging stations are often expensive to implement and particularly inefficient in rural areas.

 The Tech

Amazon has been granted a patent for a roving drone that can attach to cars and infuse energy.  The article suggests that the car battery could be recharged by the drone either when the car is idle or when it’s in motion.

The roving drone may be manually requested by drivers with low car battery via Alexa, which is already being installed in some Ford models.  Alternatively, the roving drone may be dispatched automatically if a driver is signed up with Amazon Prime or another subscription service.

Furthermore, this patent may open the door for other Amazon deliveries to mobile individuals.

Article Title: New Amazon Drones Will Charge Your Car While You Drive
Website: Green Tech Media
Link: https://www.greentechmedia.com/articles/read/amazon-ev-drone-charging-while-you-drive

 The Stakeholders Using The Tech

EV owners who subscribe to the service.

All automotive, train, airplane drivers and passengers who share the land/airspace with drones.

Amazon drone dispatchers/analysts.

Government/airspace regulators.

Street/highway patrols in case of accidents.

Highway maintenance crews in case of drone failures.

The First Three Steps

  1. Amazon needs to create a prototype that is light weight (current estimates say these drones will be 1,000lbs) and energy efficient themselves.
  2. Amazon needs to test its proof of concept to confirm that the roving drone can latch onto a moving vehicle under various weather/geographical conditions.
  3. Amazon needs to drum up support to pass legislation that allows Amazon to conduct a small live test.

Comment on The Car as an Ambient Sensing Platform

“Perhaps these car sensors will determine if you’re driving near a notoriously bad driver so that you can be on high alert as you’re passing them or they’re passing you. Perhaps sensors will determine that a nearby driver always brakes late, thus your car warns you to maintain X distance behind. Perhaps sensors will lead to every driver having a visible driving rating that you can see in your windshield. Seems like the possibilities are endless.”

Safer and Better Performing Energy Storage Technologies

170920113559_1_540x360

  1. Sustainability Problem: Rising energy demand and the need for incorporating more renewable energy in the electric grid is increasing the need for higher performing and safer energy storage devices. Category: Energy, Safety and Health
  1. Spinning a lighter, safer electrode

https://www.sciencedaily.com/releases/2017/09/170920113559.htm

  • A group of researchers from Drexel University have created new fabric-like material electrode, intended to help energy storage devices such as cell phone batteries have better performance and reduce their inherent health and safety risks associated with the toxic and flammable electrolyte fluid they contain.
  • To get rid of this dangerous liquid, the team designed an energy storage device that consists of a thick ion-rich gel electrolyte absorbed in a fabric-like material made of carbon nanofibers, thus eliminating the risk of the device exploding or catching fire (as was recently demonstrated in Samsung Galaxy Note devices).
  • The technology also allows for lighter, more durable, and better performing energy storage devices, due to the lack of binding agents needed and ability to operate safely at extremely high temperatures (up to 300 degrees Celsius).

Additional ways this technology can be utilized

  • Energy storage in the built environment is one the largest barriers to the proliferation of renewable energy due to the intrinsic intermittency of solar and wind power technologies. In NYC, fire safety codes have been a limiting factor for the deployment of lithium-ion batteries in buildings. (see: http://www.utilitydive.com/news/fire-safety-issues-dog-battery-storage-growth-in-new-york-city-slowing-dep/438290/)
  • If the energy storage device created by the scientist team from Drexel University can be proven effective on a larger scale, not just in mobile device batteries, it can potentially help solve the fire safety issues of battery storage in buildings and support proliferation of renewable energy in the built environment.
  1. Stakeholders: Renewable energy companies, local government bodies regulating energy and buildings (i.e. NYSERDA, NYC DOT, FDNY), Building owners.
  2. Next Steps:
  • Research applicability of large-scale of liquid-free energy storage technology and develop energy storage devices using the technology.
  • Update building and fire codes to allow for the deployment of these devices in the built environment.
  • Provide subsidies for large scale liquid-free batteries to building owners and builders.

http://datasmart.ash.harvard.edu/news/article/how-a-smart-city-tackles-rainfall-956

The sensors can also trace chemicals present in stormwater, and help determine how well the existing green infrastructure is performing. For example, if rainwater is prevented from entering the sewer system, or which green infrastructure designs are more appropriate for which types of precipitation (heavy vs. light rain, etc.).

Comments on Improving access to medical supplies with drones

“A very interesting concept indeed. I am hopeful that this will be the future of shopping, where drones deliver everything to our homes. However, the constraint right now is the drone technology itself. In cities with developed infrastructure, the drones will need to have a top-notch maneuvering ability to avoid buildings. Although your post is focused towards cities with less developed infrastructure, this can prove to be the next challenge.”
