The National Renewable Energy Laboratory (NREL) released a pilot version of a no-cost, no-touch software system for cities and counties across the country to streamline rooftop solar permits in late 2020
Besides gaining efficiency, local governments can count on SolarAPP to increase permitting fee revenue, enhance local resilience, establish safe solar-grid connections, and accelerate job growth in solar energy
SolarAPP is beneficial for both compliant and non-compliant solar project designs. If a system is compliant, SolarAPP will approve the design and issue a permit instantly. If a system is not compliant, SolarAPP will decline the application and clarify why the system was not code-compliant, allowing the contractor to go back and revise their application in real time
SolarAPP is compatible with local government permitting software, including Accela and OpenGov, which serve thousands of local governments across the United States
DEPLOYMENT STRATEGY NATIONALLY
NREL to start a campaign and market the app
Target marketing to areas with 150 and more days of sunshine
Unlike fossil fuels which release CO2 to the atmosphere, the waste product of ‘burning’ hydrogen is water. However, making hydrogen takes energy. If that energy comes from renewable sources, for example through electrolysis of water using renewable electricity, then the hydrogen made is called green hydrogen, as very little CO2 is emitted in the process.
The efficiency of such ‘power-to-gas’ is 65-70% today. However, the efficiency of turning hydrogen to electricity or so called ‘gas-to-power’ is up to 50%. So the round-trip efficiency, electricity to hydrogen then back to electricity, is 30-35%. Transportation and liquefaction of hydrogen further require energy, making the overall efficiency even lower.1 However, considering fossil fuel to electricity efficiency is around 33-45%,2 and as technology improves, hydrogen has the potential to be an alternative to fossil fuels. There are many companies in this space, and in North America, Plug Power (www.plugpower.com) is adopting a vertically integrated business model, while Ballard Power Systems focuses on fuel cells for mid-to-heavy duty transportation sector (www.ballard.com).
Given solar and wind power have an intermittency issue and nuclear power has a bad wrap, hydrogen and solar/wind are complementary to each other. The EU issued ‘Hydrogen Strategy for a Climate Neutral Europe’ in August 2020, positioning hydrogen to play a significant role in replacing fossil fuels.3
For hydrogen to do that, several things need to happen. First the technology needs further efficiency improvement. Second, needed accompanying infrastructure needs to be developed such as fueling stations for hydrogen vehicles. Scaling of businesses and their facilities need to happen. And all these require capital. There are signs that all these are beginning to happen. For example, Enegix, a global renewable energy developer, signed an MOU with a local government in Brazil to invest $5.4B to develop a hydrogen production facility using solar and wind energy – the largest of such projects. The project is tied to another project of electricity generation. 4
1. Problem: Electric Vehicle Charging Fragmentation Sustainability Category: Energy Management, Mobility
29% of total greenhouse gas emissions in the United States are from transportation with internal combustion engine vehicles being the highest source. With only about 1% of cars on the road being electric today, range anxiety from the lack of widespread charging infrastructure is a primary adoption barrier.
As the electric vehicle (EV) charging technology sector develops, closed charging infrastructure networks generate friction for hardware manufacturers, software developers, and drivers. Electric vehicle infrastructure developed by private network operators create silos that limit value for stakeholders. Industry fragmentation forces EV drivers to join multiple networks with varying accounts to access public chargers. The lack of standards leads to duplicative development effort to integrate charging stations and backend networks with energy systems. This limits providers from offering additional features across all providers.
2. Solution: Open Charge Point Protocol (OCPP) The Open Charge Point Protocol (OCPP) is a charging infrastructure standard for EV charging station, Electric Vehicle Supply Equipment (EVSE), and back end software communication. OCPP reduces friction and fragmentation by increasing flexibility across the electric vehicle infrastructure industry for organizations and drivers.
— OCPP is an open-source, free standard published by Open Charge Alliance (OCA) that enables interoperability between charging infrastructure hardware and software networks. — This neutral, open standard enables charging station vendors to access, share, and collect data with backend charge management operators so the widest amount of products can work together. — On the charging station, OCPP enables charging station discovery, reservations, session authorization, billing information collection, and real-time charging data. — On the backend software, OCPP enables real-time status of charging stations, remote charging session control, firmware management, and error notification. — OCPP 1.6 is a JSON protocol that was released in 2015 and is the most widely used version in market today. OCPP 2.0 was launched in 2018 and provides major data encryption security updates. OCPP 2.0.1 is the latest version and was launched on March 31, 2020.
OCPP is primarily utilized by charging station product, design, and engineering teams. Key organizations that are stakeholders in the OCPP ecosystem include:
— Open Charge Alliance (OCA):An international consortium of private and public EV infrastructure organizations that leads OCPP development, adoption, and certification. — Network Management System Providers: GreenLots and ChargeLab are two EV charging network software providers that manage charging stations across manufacturers via OCPP. — Charging Station Manufacturers: Blink and EVBox are two EV charging station manufacturers that use to connect devices to OCPP supported backend systems. — EV Drivers:Mobile applications across providers initiate and manage charging sessions. — EV OEMs: Manufacturers integrate OCPP on the in-car display to manage charging sessions.
Once a hardware or software company decides to use OCPP, the following steps are taken: 1. The product management team will integrate OCPP in the roadmap and define requirements. 2. The design team will incorporate the OCPP functionality into hardware or software features. 3. Once approved, the engineering team will develop, test, and deploy OCPP features.
Fisker reportedly made a breakthrough in solid-state batteries – and their technology could allow an EV to travel 500 miles after a single charge.
The company has filed a patent for a groundbreaking solid-state battery.
Green Car Congress reports that the patent includes claims about manufacturing processes and novel materials, saying, “Fisker’s solid-state batteries will feature three-dimensional electrodes with 2.5 times the energy density of lithium-ion batteries.” Recharging such a battery, they pointed out, would take less time than filling up a tank of gas today.
Here’s a representation of the three-dimensional electrodes:
Fabio Albano, co-founder of Sakti3 and Fisker’s vice president of battery systems.
The project is years away from completion.
Deploy when figure logistics of implementation are figured out
For this particular technology, Fisker says that it will be automotive production grade ready around 2023.
In the meantime, Fisker plans to launch its Emotion electric car at CES 2018 in January 2018
It is very impressive technology considering how slow plastic decomposes. According to the link, “PET plastic takes between 450 – 1000 years to decompose. Most PET bottles end up in a landfill, eventually contaminating lands and groundwater. William Horner, Founder and President of Totally Green Bottles & Caps, believes that the bottled water marketplace is long overdue for a 100% compostable bottle, cap, and label.” This would reduce a lot of waste that could take hundreds of years to decompose. I wonder if there would be any health effects from drinking water out of these bottles all the time.
75% of tires are made of petroleum (needed for the production of the rubber used). At the end of the products’ life most of them end up in landfills .
Michelin, thanks to a new concept, 3D printed a new kind of tire. The tires are made out of molasse (sugar paste), then turned into ethanol which is used to produce rubber replacing petroleum. Since the tire is only made of natural sources (molasse, bamboo,…), the tire is fully biodegradable. Although, thanks to the new design of the tires, their useful life should be greatly extended. Indeed, instead of changing tires when a problem arises, the new Vision tire can be modified with a 3D printer.
Stakeholders: Car manufacturers / City officials / Car owners
Michelin needs to research markets to find countries/ citis which are early adopters of new technologies;
They need to contact the government of this country/city to run some test in the city and have approval of their technology being used
They need to find car manufacturers that are also early adopters to pilot their technology
Other article comment: The tiles are also gathering data that can be used for better understanding pedestrians habits and crowd flows . This type of information is useful to commerces but also for cities.
Harvesting mechanical energy from a person’s everyday ordinary actions – or nature’s actions – is both expensive and inefficient. Therefore, significant amounts of energy are wasted.
An international team of researchers have developed a technology called Twistron Harvesters, which is essentially carbon nanotube submerged in ion gel that is weaved into yarn. A small electric current is generated when the weave is stretched out. The carbon nanotubes can potentially replace external voltages which were previously used for this type of mechanical energy harvesting.
As seen in the photo below, clothing can have this carbon nanotube tech weaved into the fabric. Electricity can be simply generated as a person breathes in and out, stretching out the weave. The tech was also tested in ocean water. Waves can naturally stretch the harvesters, generating power.
The power generated is still not sufficient for home lighting or EV charging, however scientists are optimistic that improving the tech and dropping carbon nanotube pricing will make this energy generation method a possible power charging option for wearables.
I imagine this application can be extended to other supply/demand service scenarios such as assessing wait times for entering events (i.e. concerts or baseball games) or restaurant seating availability. Certainly, this will lead to less demand for crowded services, and thus an influx of supply! “Nobody goes there anymore – it’s too crowded.”
A smart Internet connected elevator/escalator can alert owners in the event that it needs service before failure, inconvenience or rider injury occurs. It also provides the owner/operator with detailed information on the performance and usage of the equipment.
3) The stakeholders are anyone owning or managing a building that utilizes elevators.
4) I would market the technology to building management companies and suggest that it might lower insurance rates for the building by reducing the likelihood of rider injury or entrapment.
My comment is for the Energy Producing Homes: I wonder if the homes could be manufactured offsite semi-preassembled, further reducing the CO2 footprint of construction.
Livestock farming has an enormous impact on climate change. In Argentina, livestock agriculture is prominent with over 51.2 million cows residing in the country. In the United States, methane emissions from animals contribute to 22% of our greenhouse gas emissions. With that being said, methane is also one of the most impactful GHG’s. It is estimated that one cow produces enough methane in a year to do the same amount of damage as 4 tons of carbon dioxide.
The Paris Agreement called for a GHG reduction to prevent the Earth’s temperature rising an additional 2°C compared to temperatures from before the industrial revolution. In order for this to happen, livestock agriculture will have to make strides to reducing their emissions. Aside from the population becoming vegan, there have not been many solutions put forward to make an impact up until recently.
The National Institute of Agricultural Technology (INTA) has created a backpack to mitigate climate change by capturing methane emissions from cows. The backpack would be worn on the cow and captures methane by inserting a tube into the cow’s rumen, or a digestive organ where the gas is produced. Researchers say this does not harm the cow and would capture up to 300 liters of methane per day. This methane can then be condensed and used as fuel for “light” activities such as cooking or lighting.
Although this seems like a humorous solution, it is encouraging to see INTA taking a stab at the methane problem!
Check out my notes below for a summary of the details.
Sustainability Problem: Energy and Climate Change
The following bullet points summarize Argentina’s invention:
Methane produced by cows as a result of digestion accounts for 25% of all methane emissions in the atmosphere
On average, one cow produces 300 liters of methane per day
The INTA created a backpack that is inserted through the cow’s skin which captures gases emitted through its mouth or intestinal tract
The backpack collects the methane and it is then condensed and used to power activities such as cooking, lighting, or driving a car
Organizational stakeholders that would be involved in this technology are:
National Institute of Agricultural Technology of Argentina
Food and Agriculture Organization of the United Nations
Local farmers in Argentina
Facilities Management Team
The following steps should be taken to deploy this technology:
INTA should test this technology on a few local farms in Argentina.
This technology could be introduced on a continental or international stage at the UN, to debate the efficacy and legality of using this on animals.
Lastly, management teams can be established to discuss maintenance and implementation of these on farms.

Tidal power or tidal energy is a form of hydro-power that converts the energy obtained from tides into useful forms of power, mainly electricity. Although not yet widely used, tidal energy has potential for future electricity generation. Tides are more predictable than the wind and the sun.
Sustainable Problem: Energy
Tidal power or tidal energy is a form of hydrophone that converts the energy obtained from tides into useful forms of power, mainly electricity. Although not yet widely used, tidal energy has potential for future electricity generation. Tides are more predictable than the wind and the sun.
Potential: Worldwide potential for wave and tidal power is enormous, however, local geography greatly influences the electricity generation potential of each technology. Wave energy resources are best between 30º and 60º latitude in both hemispheres, and the potential tends to be the greatest on western coasts.
One type uses floats, buoys, or pitching devices to generate electricity using the rise and fall of ocean swells to drive hydraulic pumps.
A second type uses oscillating water column (OWC) devices to generate electricity at the shore using the rise and fall of water within a cylindrical shaft. The rising water drives air out of the top of the shaft, powering an air-driven turbine.
Third, a tapered channel, or over topping device can be located either on or offshore.
Comments to Wakati : Keep food fresh using solar power by RS3686 by AV2698 :
Unlike a refrigerator, the Wakati does not control temperature and, therefore, cannot store fruit and veg for long-term periods. Wakati have shown that a one or two-day shelf-life in a hot climate can be increased to 10 days. In developing countries this can be significant because some food will not go to waste and some companies can even profit.
This machine could harness the energy from water that evaporates from existing dams and lakes in the U.S. It could provide up to 2.8 billion megawatt hours per year or about 2/3 of the electrical production in the U.S in 2015.
3: Stakeholders are anyone currently using electricity generated by burning fossil fuels. Additional stakeholders would be less developed nations who would not have to spend billions upgrading their infrastructure to burn fossil fuel burning generating plants.
4: If this technology can be refined it would sell itself to countries, states and cities currently using fossil fuels to generate electricity or facing huge infrastructure upgrades to generate electricity using fossil fuels.
My comment: For the rapid electrical cell recharging technology article;
I particularly like the safety improvement offered by this technology. The removal of the membrane in the fuels cells which become clogged and cause overheating and fires makes this technology important for the future of transportation fuels cells being utilized on a larger scale
