Graphene battery storage:

Graphene structure photoGraphenano bike batteries image

Sustainability Problem: 

Currently used batteries such as lithium-ion and lead acid batteries take hours to charge and have short lifespan for charging and discharging. They can also be harmful to the environment.  Lithium-ion batteries are unstable and can explode and cause fire.

Technology:

Graphene battery storage is under production at Graphenano, a Spanish based company that develops diffierent technologies using graphene. Graphene is a monolayer carbon lattice that is harder than diamond. These new battery  offers much higher energy density than Lithium-ion (1000 Wh/kg vs. 200Wh/kg on a Tesla Model S), has no fire or explosion danger unlike Li-ion, and charges in minutes, lasts longer , and 3 to 5 times smaller than Li-ion battery.

These battery can be used for electric bikes, electric motorcycles, and to store solar energy. Grabat company shows advantages of graphene-based battery over other batteries:

Grabat say that their battery chemistry will drastically decrease charge times

Grabat suggest that the current energy density of their battery chemistry is far ahead of the competition

Tesla’s CTO Just Backed A Startup That Makes An Ice Battery

Source: http://fortune.com/2016/08/03/tesla-cto-ice-battery/

Sustainability Problem

One of the biggest problem in electricity is the peak load. The grid has to meet all the demand every time and needs to be ready for that. So the difference between peak demand and normal time there are lots of power plants that are resting. Besides If  you shave even a small amount from peak demand and add it other times of the day it would same millions of dollars to government as the highest bidder who is helping to meeting highest demand on a certain time is the one who determines the cost of electricity to all of the power generators. This emphasizes the importance of storage.

Technology Article Summary

 

In this article a startup called Axiom Energy claims to find a solution for Supermarkets for the peak hour. Company sells technology that plugs into super market refrigeration units and uses tanks of frozen salt water as a way to store energy and lower supermarket energy bills.

During peak times this supermarkets shift to use this technology, frozen salt water tanks, to keep cool the refrigerators and at nigh when the demand and electricity prices are low they can freeze the tanks with electricity. They called it as Refrigeration Battery. It is basically using thermal energy.

Stakeholders

First supermarkets later it can be various places like data centers, cold storage units etc.

But on the big picture as it supports shaving on peak demand every tax payer would benefit.

Deployment

 

Right now although this is a new startup they are just getting their first commercial systems installed. (https://www.greentechmedia.com/articles/read/Axiom-Exergy-Raises-2.5M-For-Thermal-Energy-Storage). Besides they have got attention of celebrities of tech world thus i think the future is bright for them

 

Organic mega flow battery

Sustainability Problem

Depleting fossil fuels and its consequent  environmental impacts on climate change means alternative sources of energy need to be found, and soon.

Technology

The organic mega flow battery is an economically feasible option for storing  energy. This is particularly useful for renewable technologies such as solar power and wind power which rely on sunlight and wind power. Essentially, the flow battery stores the excess energy generated from these technologies and is available when either sunlight or wind is unavailable. They are much more efficient than the traditional batteries used to store energy from wind and solar power.

Stakeholders

  • Energy companies and consultants
  • Energy consumers
  • Investors
  • Government

Implementation

  1. Conduct a pilot test and use it to complement one of the ongoing solar projects in a region- possibly Africa (Tanzania) which has abundant solar projects.
  2. Collect data analytics and present data in energy conferences to attract investors
  3. Collaborate with city governments and implement with an upcoming Smart City project.

Slingshot Can Provide Clean Water to Many

Source: http://www.theepochtimes.com/n3/1410195-slingshot-segway-inventor-says-end-of-clean-water-is-near-built-incredible-h2o-purifier/

“‘SlingShot’: Segway Inventor Says End of Clean Water Is Near—So He Built a Solution”

1)Sustainability Problem – Clean drinking water is becoming more and more scarce on Earth.

2) – More than 3.5 million people die every year from water-related diseases, and almost 900 million don’t have access to a safe water supply.

– The Slingshot is a “vapor compression distiller” that uses solar energy to boil, distill and vaporize the bad gunk and turn it into clear and clean drinking water. It was created by inventor Dean Kamen and his inventing company, DEKA Research and Development

–  Each Slingshot can purify 1000 liters of water per day, which can essentially support the water needs of 100 people. Plus it only uses a small amount of electricity.

– Slingshot is expensive to produce so Kamen he realized he must partner with companies that can distribute Slingshots globally.

3)Organizational Stakeholders – DEKA Research and Development, Consumers, Private companies used for public-private partnership

4)Deployment Steps

– Continue research to drive costs down.  Third world countries will not be able to afford Slingshots at current cost.

– Find key areas that are in most need of clean water without access to it.  Target these places and determine whether Slingshot would be a viable solution for them.

– Create public-private partnerships in these areas in order to set up Slingshots for the people to use.

Uber for trucks?

std

Problem: Carbon Emissions

The trucking industry is composed of small, disparate actors who require brokers to organize shipment routes. This inefficient system often leaves trucks returning to their home bases empty, which is a waste of gas and contributes unnecessarily to congestion, accidents and carbon emissions.
The Solution:
  • Several companies have developed Uber-like apps that send pings to a nearby trucker about a shipment.
  • Like Uber, the trucker can either accept or reject the pick-up.
  • Whereas currently a broker is required to make hundreds of calls to arrange a shipment, the app uses algorithms applied on big data to understand and respond to shipping trends.
  • Ensuring trucks are always full decreases the total number of trucks on the road, which reduces carbon emissions, traffic congestion and accidents.
Stakeholders:
The 3 main companies developing apps.
Trucking companies.
Major shippers (Amazon, Walmart).
Steps to implementation:
1. Expand mobile platforms to span the entire country.
2. Engage more trucking companies and their customers to use the apps.
3. Analyze impacts of apps on trucking routes, congestion, carbon emissions, cost etc.

Osmotic Power: A new source of clean energy

Sustainability Problem

The impacts of climate change are clearly visible in this day and age. Rising temperatures as a result of CO2 emissions from fossil fuels such as oil, coal and natural gas will only add to this problem.

Sustainable Technology

Researchers have developed a system that generates electricity from osmosis with unparalleled efficiency using seawater, fresh water, and a new type of membrane just 3 atoms thick.  A 1 m² membrane with 30% of its surface covered by nanopores should be able to produce 1MW of electricity. This is enough to power 50,000 standard energy-saving light bulbs.

Stakeholders

  • Investors
  • NGO’s
  • Electricity generation companies
  • Government

Implementation

  1. The effectiveness of this clean energy method has only been implemented on a small scale. The next phase would be to identify potential investors by attending energy efficient conferences.
  2. Identify a electricity generation company that is transition towards the usage of clean energy. Conduct a 6 month trial period during which time staff go the electricity generation company are trained. Provide workshops to further educate the employees in the company.
  3. Once the effectiveness of osmotic power as a means of clean energy is more apparent to the general public, continue to seek out more investors to increase large-scale implementation.

Home battery for self consumption-sonnenBatterian

1. Sustainability Problem

Dependance on fossil fuel to generate electricity is a global issue that needs to be addressed, considering the high rate of depletion as well as the impact on climate change.

2. Technology

The German battery company Sonnet launched a home battery for self consumption at a 40% reduced cost. The battery is basically an “eco pack” that is designed to maximise on-site solar consumption in markets where net metering is being phased out. The sonnenBatterien can optimise the energy supply and demand to such a degree that an integration of 100% renewable energy within a community is possible – 24/7. This will reduce dependance on fossil fuels and improve air quality.

3. Stakeholders

  • Clean energy providers
  • Residents
  • Businesses
  • NGO
  • Government

4. Deployment

  • Extensive testing of the product in households. Additionally integrate into businesses to see how well it fits into large systems. Report on costs saved and amount of fossil fuel consumption reduction.
  • Once data on this has been publicised, continue increasing awareness of product by attending energy efficiency conferences.
  • Current pricing of installing is quite high, therefore partnering with another company  with similar interests may be in the best interest at the beginning phase of implementation. This will allow you to minimise risks as well as provide a temporary financial cushion when installation prices are reduced.

The World’s First Molecular Air Purifier

Sustainability Problem:

Air pollutants are trapped indoors. Poor air quality can cause headaches, fatigue, nausea, congestion and worsen asthma and allergies. Most HEPA filters trap but do not destroy air pollutants such as mold, bacteria, viruses, allergens and VOCs (Volatile Organic Compounds).

Technology: 

Molekule device is billed as the  the world’s first molecular air filter. Using Photoelectrochemical Oxidation (PECO), the air purifier breaks down pollutants extremely quickly and said to destroy them up to 1000 times smaller than what a HEPA filter can. According to Molekule, the company that developed this product, PECO is “a type of oxidation process that works by shining light on an electrochemical cell in order to generate a chemical reaction that break down pollutants”.  

Source: http://www.treehugger.com/gadgets/molekule-air-purifier-breaks-down-air-pollutants-molecular-level.html

Stakeholders:

  • Molekule Company, the developer of Molekule Air Purifier
  • general public especially people with asthma and allergies
  • researchers
  • investors

Implementation: 

  1. Extensive testing of the product by independent labs to verify that Molekule byproducts are completely harmless elements that normally exist in clean air , and that air pollutants aren’t trapped in the filter ensuring that only clean air is released back into the area.
  2. Public launching of the Molekule with an offering of early bird-price of $499 (future retail price is $799). 
  3. Future price may be too high for the general public. Further research on reducing the cost should be done so this product can be more attractive to the general public.

Growing cement

cylinder_samples-960x525_c1. Problem: Energy

The cement industry requires massive amounts of energy and is a major carbon emitter, second only to the fossil fuel industry.

 

2. Technology: BioMason cement.

  • BioMason cement uses bacteria for hardening, rather than heat, cutting out the most significant energy-using and carbon-producing step in the manufacturing process.
  • The concept mimics the formation of coral reefs, wherein living organisms calcify sand and minerals, forming a very durable cement-like structure.
  • The dry materials can be shipped anywhere. All the recipient needs to do is add water and form into the desired shape. This reduces logistics costs (e.g. cement mixers, shipping).
  • Materials are all sustainably sourced.

 

3. Stakeholders

Construction firms.

Plant currently manufacturing the cement.

Government buildings departments.

 

4. Next steps to implementation

a) Meet with buildings departments to prevent unforeseen building code compliance issues.

b) Secure financing for plant expansion.

c) Identify firms seeking to reduce construction-related carbon emissions.
