The solution – hydro-micro grid

LE-Graphic.jpg

  • LucidEnergy is an American company based in Portland that creates hydro-turbines for municipal water pipes.
  • Many cities receive their water from remote and elevated locations. When gravity “powered” water flows towards a city, strong pressure (i.e., water speed) builds up in the pipes –  LucidEnergy harnesses this power by installing pipes with an intergrated micro-turbine.
  • The system is scalable and can generate between 18kw to 100kw based on the diameter of the pipe system and the flow rate.
  • The power generated can be sold to a 3rd party (e.g., a utility company via a P3). Anticipated return over the investment is 10 years.
  • The solution has been tested successfully in Portland, Oregon and Riverside, California.
  • The company is currently working on the 2nd generation of its LucidPipe turbine design, “which will significantly increase power output, operate across a wider range of pipe sizes and flows and significantly reduce capital cost”.

Water from thin (but humid) air!

Sustainability problem

Water security (both quality and quantity)

The problem

Water is not only necessary to survive, but it is also a fundamental building block of a decent quality of life. Nevertheless, nearly 800 million people do not have water security (link).  Fresh water, which includes safe drinking water, account for less than 4% of all the water of the plant (link). Moreover, these water bodies are localized and accesses to them is limited. In short, there is an urgent need for potable water in many parts of the world. On the other hand, air is very abundant….

The solution – Water from air!

product_03_large-1.png

  • Water-Gen is a Israeli company that produces a line of Atmospheric Water Generators (AWGs) and de-humidifing products.
  • The units only require electricity to operate. The company’s largest generator can  produce up to 6,000 liters per day. Standard operating conditions are 26.7°C and 60% Relative Humidity.
  • The company claims its solutions are ideal for cities in developing countries and has identified 12 cities (ranging from Jakarta, Indonesia to Salvador, Brazil) that can greatly benefit from the technology, which can be integrated into existing buildings,
  • One of the nice features about the water generators is that their optimal operating period (when humidity peaks) is at night (when electricity demand is low).

img-04-1.jpg

Stakeholders

  • Individuals in developing countries with poor access to water
  • Individuals in developed countries who live in areas with contaminated water (e.g., Flint, Michigan)
  • Army and Science facilities that are “off the grid”.

Implementation

Step 1 – Partner with cities, organizations and countries that are in need for humanitarian aid  for pilot programs to increase public awareness.

Step 2 –  continue to improve the product and make it more “renewable energy friendly”, which will increase its attractiveness for communities with poor access to electricity.

Step 3- Expand operations and open additional factories that will allow the company to reach economies of scale, which will lower the product’s price.

Comment on A Bay Area Startup Spins Lab-Grown Silk (JANEVAMORFAW):

Thats is a very cool idea with great potential. I hope that the company will be able to cheaply produce enough “silk” and have a global presence so that they will be able to bring about a real change.

Two things stand out to me in this technology: 1) Is the farming of the planets the company extracts sugar from sustainable and are these plants widely available?  2) Can the company bring the technology to a sufficient scale so that it can “move the needle” and meaningfully make the apparel industry more sustainable?

Route Optimization Software for Waste Management

1) Sustainability Problem:

In 2014, in the United States, about 258 million tons of Municipal Solid Waste were generated. (EPA.gov) In addition to the environmental impact of the waste itself, the waste has to be hauled and carted to landfills or recycling facilities. This is performed by heavy-duty trucks which produce significant pollution per mile.
Category: Energy/Water & Waste Management

2) Technology Summary:

Route optimization software can ensure that fleet operators are driving the minimum necessary distance to efficiently pickup and deliver waste to the appropriate intermediate facility.
From the article:

Joe Burkel, vice president of digital operations and process improvement at Republic Services, estimates that a one percent reduction in total fleet miles traveled can save more than 631,000 gallons of fuel. The carbon emissions savings from that would be equivalent to removing 1,400 cars from the roads, he says.

3) Organizational stakeholders

  1. City councils
  2. Procurement officials in each municipality
  3. Waste management officials
  4. Software vendors

4) Steps in deploying this technology

  1. Establish SOW’s and service contracts with route optimization software vendors
  2. Establish data integration & data governance protocols for incoming data streams into municipal data warehouse
  3. Work with drivers unions to get buy-in on relying on new technology for their operations
  4. Measure and evaluate software effectiveness in mileage reduced and iterate on route tweaks

Smart Fishing Technology

crab boat2

Blue Ocean Gear, a participant of the Ocean and Clean Technology Program in Nova Scotia was selected as a round one winner for the Blue Solutions Startup Challenge. The company focuses on making smart commercial fishing gear that minimizes wild life entanglements and energy savings for boat operators by providing them with real time data on catches and equipment. This benefits all the stakeholders involved such as the operators, fisheries, environmentalist, consumers and governing agencies. The technology is fairly simple and off the shelf, and has already been deployed in the industry. It works by having the gear trap cages send a signal up to the buoys that they’re full and then a signal is sent to the operators via an app. This allows for the operator to save on fuel cost by not having to blindly travel to pick up possibly empty cages. The gear also notifies operators of possible marine life entanglements so that could alert the proper rescue agencies to save the wildlife. Another feature is that the gear provides retrieval information data for lost gear which saves on lost gear costs.

Reply to Pablo Mandiola’s “Elevated Bike Path to Fight Congestion”

This is an interesting concept that has been adopted in the past for buses and light rail congestion in some cities. I’m not certain what the data suggested concerning its success or failure, but it seems like a good solution.

Print Your Own City: 3D printed furniture from plastic waste

Problem: plastic waste (it is estimated that Amsterdam residents generate 23 kg of plastic waste per person annually)

Solution: 

  • Rotterdam-based studio The New Raw is turning household plastic waste into furniture for public spaces
  • Household plastic, including plastic shopping bags, can be melted into a base product for large-scale 3D printing
  • They have also launched a campaign called “Print Your City!” to redesign urban spaces, whereby communities’ own collected plastic can be used to make the same furniture used in their community
  • The annual plastic waste from two people is enough to produce one bench such as their prototype – the XXX bench (in collaboration with Actual,  who specialize in large-scale bio-based 3D printing).

Poultry waste to energy

Problem: While biomass accounts for 73 percent of renewable energy production worldwide, crops grown for energy production burden land, water and fertilizer resources. Also, environmentally safe disposal of poultry excrement has become a significant problem.

Technology:

A new study shows that turkey excrement may have a future as a fuel for heat and electricity. Treated excrement from turkeys, chickens and other poultry, when converted to combustible solid biomass fuel, could replace approximately 10 percent of coal used in electricity generation, reducing greenhouse gases and providing an alternative energy source. Converting poultry waste to solid fuel, a less resource-intensive, renewable energy source is an environmentally superior alternative that also reduces reliance on fossil fuels.

The researchers have compared the production, combustion and gas emissions of biochar, which is produced by slow heating of the biomass at a temperature of 450°C (842°F) in an oxygen-free furnace with hydrochar. Hydrochar is produced by heating wet biomass to a much lower temperature of up to 250 °C under pressure using a process called hydrothermal carbonization (HTC).

The researchers found that poultry waste processed as hydrochar produced 24 percent higher net energy generation. Since poultry waste hydrochar generates heat at high temperatures and combusts in a similar manner to coal, it can replace it as a renewable energy source.

Researchers also showed that higher HTC production temperatures resulted in a significant reduction in emissions of methane (CH4) and ammonia (NH3) and an increase of carbon dioxide and carbon monoxide.

Thus, treated poultry waste could significantly reduce greenhouse gas emissions associated with electricity generation and agricultural wastes.

Stakeholders:

  • Poultry farm owners
  • Biomass handling agencies
  • Biofuel consumers: companies, government agencies, individuals

Implementation:

  • Further assessment with hydrothermal carbonization (HTC) reactor should be conducted to confirm the assessments from this laboratory-scale study
  • Collaboration with poultry farm owners for collection of poultry waste and then treating it for generating renewable energy

Plastic Roads

Sustainability Problem: 

Roads laid with asphalt are unsustainable, brittle and they contribute over 1.6 million tons of carbon dioxide around the world each year.

Solution: Roads made from recycled plastic are stronger, greener and maintenance-free

  • It takes less time to lay than asphalt
  • Durability is likely to be three times higher
  • Plastic is compressed into prefabricated sheets, which are easy to transport and install on site
  • Each sheet is recyclable and replaceable – making it very easy to maintain roads
  • These sheets are light weight and hallow, can suck in water to avoid flooding and allow plumbing and cable installations underneath

Stakeholders: City municipality, road contractors, manufacturers of prefabricated plastic sheets, academia and scientific researchers involved in further evolving this technology

Deployment: This technology is tried and tested in couple of cities mainly in Netherlands, UK and the US

  • Draw experience from the cities where this technology is already adopted
  • City municipality to engage with manufactures of prefabricated sheets and road contractors to understand the feasibility and scale of deployment
  • Start with changing asphalt roads with this technology in parks, local communities before moving to main city roads or highways. This will help in testing the durability, traffic load and also creating awareness
