1. Sustainability Problem: Energy

More than 620 million people, about two-thirds of the population in Sub-Saharan Africa, do not have access to an electrical grid. These populations rely on the use of Kerosene that contributes to CO2 emissions and indoor air pollution.

2. Technology Summary

  • M-Kopa IV Solar Home System is a pay-as-you-go home solar system that combines uses micro payments and mobile technology to provide electricity to people in Africa who are not connected to the electrical grid.
  • The system is rent-to-own: the unit requires a deposit of $35 and then customers make 365 payments of $0.43 though M-Pesa, a mobile money system to purchase the system.
  • The unit includes a solar panel, a control unit, two LED light bulbs, one portable LED flashlight, a rechargeable radio, and a USB port for charging cellphones

3. Stakeholders

  • NGOs
  • Electricity companies in Africa
  • Individuals without connection to electrical grid
  • Governments
  • M-Pesa
  • M-Kopa

4. Deployment

  • Increase awareness of product by performing demonstrations in common community areas

Blockchain for renewable energy

Sustainability Problem:

  • Unreliable centralized grid management or utility system which keeps track of your consumption.
  • Lack of decentralisation of energy
  • Pricing for micro grid energy consumption based on usage

Technology:

Blockchain allows consumers to produce energy, and to trade it directly with other consumers in a peer-to-peer network.

SolarCoin is a digital currency like bitcoin. The difference with bitcoin is that SolarCoin is not “mined“ by letting a computer work out some computations. It’s mined by producing renewable energy. If your domestic solar panel creates 1 MwH of energy, you receive 1 SolarCoin.

This solarcoin is kept in an online wallet that you can update manually or let it update and earn automatically by, for now, a Smappee energy monitor (soon other energy monitors will follow).

This same wallet can be used for three things:

  1. to store the coins you create with your solar panel,
  2. to receive payments for the energy you sell, and to,
  3. pay for energy you trade with your neighbors.

In fact, you won’t even need to install energy production at your home. It will become perfectly possible to buy a solar panel, install it anywhere and collect SolarCoins.

Another benefit is that the entire transaction remains transparent due to a shared ledger amongst the neighbourhood.

Stakeholders:

  • Blockchain currency issuing agencies
  • Domestic users of renewable energy smart grid
  • Local public Utilities
  • Solar system installers and manufacturers

Next steps:

  • Siemens has set up a pilot project in Brooklyn where a mini and smart grid for 10 homes early last year, which is due to expand and include a school, hospital and park this year and potentially the entire neighbourhood by 2018.
  • Other companies and entrepreneurs should look at blockchain as a valuable way to share and track utilities.
  • Policy for enabling such technology to take flight so that it can reach scale quickly
  • 1,613,853.5 SolarCoins have been granted so far, in 41 out of 215 countries

Renewable Energy for Everyone

1. Sustainability Problem: Access to Renewable Energy

Renewable energy is a key piece of the puzzle to creating a low-carbon future. However, most people can’t personally support renewable energy for various reasons, including not being a homeowner or owning a home in a location that’s not suitable for renewable energy.

Category: Energy

2. Technology Summary

  • Technology company Arcadia Power has created an online platform that allows anyone living in the 50 states of the U.S. to support renewable energy projects when paying their utility bills (regardless of whether they buy or rent, where they live, their utility provides green energy options, etc.)
  • Customers pay their utility bills through Arcadia, who in turn pays the customer’s local utility for the energy the customer consumed. Meanwhile, Arcadia offsets (buys and retires) all of the consumed energy with certified RECs.
  • Navigating buying and retiring RECs is not something that individuals could easily do before this platform and participating in community solar projects is not available to anyone living anywhere in the U.S., as the projects tend to look for “local” subscribers.
  • Arcadia makes putting your weight behind renewable energy easy (you don’t have to switch your utility) at a reasonable cost (switching to 50% renewable energy is free, switching to 100% renewable energy costs 1.5c/kWh)
  • The customer also benefits from a streamlined analytics tool that shows how much energy the customer is using, environmental impact, and what projects the RECs are coming from.

3. Organizational Stakeholders That Will Need to Use the Technology

The company currently is targeting individuals (renters and homeowners). I could see this tool also being attractive to small- and medium-sized companies that can’t or don’t want to invest in solar panels on their roofs for similar reasons as individuals. Depending on the structure of the company, stakeholders to use the tool could be the facilities and/or finance departments.

4. Steps in Deploying This Technology

  1. Find project owners and developers to partner with to acquire their RECs
  2. Negotiate REC purchasing agreements with these partners
  3. Educate individuals and companies on renewable energy, RECs, and the platform to get them to try the free option first

Solar Wallpaper

The Sustainability Problem

While solar panels have proven their effectiveness, many things about the way we makes solar panels today serve as barriers for use. One such problem is precisely that they have to come as panels made of non-flexible material and whose weight can add up once you place many panels onto a surface. As such, there are limited places where one could apply solar panels, and there is definitely a lot of concern around load bearing constructions.

The Technology

Sunflare, a company in China, developed a new solar surface that does not require panels. According to this article, they describe the new technology as:

Compared to traditional crystalline silicon solar panels, Sunflare solar panels are flexible because they do not use a glass substrate — rather, its substrate is a thin, high quality stainless steel. Likewise, Sunflare solar panels are lighter and thinner than traditional crystalline silicon because they are made of thinner layers of chemical elements and a lighter, stainless steel substrate.

“Our solar panels are easier to install because they don’t need a frame to support the panels,” said Gao. “In fact, the panels can be secured to any surface with a special double-sided tape.”

Given this development, there are now many new applications for the solar wallpaper, allowing a wider range of surfaces where they can be placed.

Stakeholders

  • Other solar technology makers whose businesses may be affected
  • Current users of solar panels who may want to switch or complement their current systems
  • Current non-users of solar panels who found the cost or weight of panels too prohibitive but can use solar wallpaper
  • Environmental agencies and nonprofits

Deployment

  • Create demo buildings for easiest uses of solar wallpaper (in factories, logistics centers, offices, etc.)
  • Create case studies for innovative uses of the solar wallpaper material (solar roads, solar bus stands, etc.)
  • Create payment plans that allow more people to afford the technology

Smartflower POP Solar System

Sustainability Problems:

The use of fossil fuel for generating electricity contributes to climate change. Although many people can install solar panels on their rooftops, some cannot do it due to issues with roof structures or shading from nearby buildings. As well, rooftop PV usually have an efficiency of 25% or less.

 Technology:  Portable Smatflower POP Solar System Produces 40% More Energy

The smartflower POP system automatically sprouts to open itself as an 18-square meter flower-like array as the sun rises. Every morning it also cleans itself. With a dual-axis tilting system it tracks and faces the sun throughout the day for maximum efficiency.

Being portable, it can be brought by the owners to their next home when they move.  It has batteries that collect excess energy during the day and so power can be available at night. Aside from these features, the owners can monitor their energy accumulation, usage and direct it to whatever use they want, whenever. They can charge their car at night and use it during the day.

Stakeholders:

  • Homeowners
  • Business-owners
  • Government offices
  • Researchers
  • Policymakers

Implementation:

Propose the first 3 steps in deploying this technology.

1) Although the costs for installing solar panels are plummeting, there is still a need to do more research on how to make this technology available to most people. Dual-axis tracking is expensive so research on how to make this technology less expensive should be done. Cost can also be reduced by using efficient but less expensive batteries. Further research on how to reduce battery cost and tracking system should be accelerated.

2) Research on designing similar portable solar system should also be taken in order to increase competition and reduce the price of this technology.

3) Government and policymakers can help homeowners and business-owners through incentives on the use of clean energy such as sales tax exemptions or rebates.

 

 

Solar tents to preserve fish in Malawi

1) Energy

Problem: In Malawi, drying fish is currently achieved by chopping down trees and burning the logs, which simultaneously removes a carbon sink and produces additional carbon emissions. 

2)  The technology: solar tents: http://www.aljazeera.com/news/2016/06/tech-solar-tent-boosts-malawis-dried-fish-industry-160609125320780.html

– A new “solar tent” allows fisherman to dry their fish only using only solar energy.

– A polyethylene sheet is hung over a wooden frame shaped so as to maximize the captured solar heat and ensure optimal airflow.

– The tent is more sanitary than the wood-burning open-air drying, which exposes the fish to dust, pests and contaminants. Fishermen thus lose fewer fish to spoilage.

– Farmers get a higher price for cleaner, higher quality dried fish and don’t need to cut down as many trees (just enough for the wooden frame, which can be used for years).

– Sustainability is paired with economic development.

3)   Stakeholders

– Local and international development NGOs

Fish buyers

–  Local councils in fishing communities

 Fishermen

4)   The first 3 steps in deploying this technology

  1. Perform research to compare economic and environmental impacts of an average wood-burning fishery compared to a solar tent fishery based on the pilot project.
  2. Identify fishermen using wood-burning strategies and gauge interest in solar tents.
  3. Solicit funding from local and international NGOs to provide credit and/or grants to build tents for interested fishermen.
