Phazr – Compact solar energy storage pack.

1) Sustainability problem: Cost of installing battery storage for solar energy. Area: Energy. 

  • The cost of lithium ion batteries in recent years has fallen from $1000 per kWh to around $200 per kWh.
  • Despite this falling cost, installation of batteries can cost a lot. The industry average is around $150 per kilowatt-hour just for installation costs at large scale, which is almost reaching parity with the price of the battery itself.

2)  Technology

  • The Phazr is a thin rectangular battery, 20 inches by 10 inches, that clips directly onto the back of a solar module. Phazr takes a distributed approach to storage.This cuts out the heavy lifting and more nuanced electrical work required to install many batteries
  •  Currently, there are two models: one designed for 60-cell solar panels that provides 300 watts power and 650 watt-hours of energy, and one designed for 72-cell solar panels at 350 watts and 810 watt-hours.​ Which gives about 2.3 hours of backup duration. Phazr uses a lithium-iron-phosphate chemistry, which is known for improved safety in its materials and thermal behavior compared to typical lithium-ion chemistries.
  • The install cost for Phazr is approximately $500 per kilowatt-hour all in. That includes parts and labor. The batteries utilize the same inverter as the solar, so no additional inverter purchase is necessary.

  • Large private businesses switching to solar energy.
  • States with large solar projects in their RPS.

4) Deployment 

  • Partner with large solar manufacturers so that Phazr can be installed along with their panels on large projects.
  •  Record cost savings achieved by using Phazr batteries and use this data to bid ti large private customers
  • Partner with states like California with large solar portfolios that need battery storage to meet demand during peak hours.

“By charging the Smog Free Tower with a small positive current, an electrode will send positive ions into the air. These ions will attach themselves to fine dust particles. A negatively charged surface -the counter electrode- will then draw the positive ions in, together with the fine dust particles. The fine dust that would normally harm us, is collected together with the ions and stored inside of the tower. This technology manages to capture ultra-fine smog particles which regular filter systems fail to do.”

Smart Urban Growth Tackles Mobility and Electricity Distribution Concurrently

Cities can get smart taking control of their electrical grid and electric vehicle (EV) charging infrastructure as a means of addressing urban growth.  Boulder, Colorado is making a run at it but few outside Germany have taken a serious move in this direction for it requires a long-term vision.  Seeking this urban planning route is not always initiated for economical reasons.  Boulder, for instance, is driven to engage as a means of increasing renewable energy sources in their electricity generation fuel mix.  Here’s the catch, this approach may not a scalable or sustainable solution for all cities  Mega cities; no way anytime soon.  Rural environments; not likely ever needed.  So, Boulder just happens to sit in the Goldilocks Zone but even with it being “just right” the increasing digitalization of the electric grid and new sources of distributed energy will make this endeavor a tenuous pursuit.

Years ago I was involved in dozens of negotiations with municipalities throughout the United States, Canada, and Mexico.  Many desired to “take control” of and then offer, as a public service, wireless Internet services for their citizens.  The complexities in equipment management and selection, maintenance, and budgeting were often solely regarded in the context of whether to make the WiFi a free or a for a fee amenity to subscribers.  Thing is, that’s not where the root challenge existed.  Even a little bit of education in these matters achieved a stakeholder stalemate for trying to figure out how to convert a privatized service into a public good without causing bias to an ongoing free market was no simple matter.  The concept of a public-private partnership was alien.

Dealing with increasing urbanization today requires a systemic stakeholder analysis and just the right sitting of pilot efforts in advance of any at-scale execution plans.  To date few cities have taken this approach but Toronto, Canada is on the way.

“...We are designing a district in Toronto’s Eastern Waterfront to tackle the challenges of urban growth…Sidewalk Toronto will combine forward-thinking urban design and new digital technology to create people-centered neighborhoods that achieve precedent-setting levels of sustainability, affordability, mobility, and economic opportunities” – Sidewalk Labs

JMB2408 COMMENT TO ANOTHER BLOG POST (Leaf Plates):

This is an excellent solution to consumption and in turn waste. If this was a compostable solution that can be put to use in the local houseplant or compost pile then we’re talking about a dream conversion in consumption to waste. The other thing that would be amazing is to see this scale to shipping boxes or other high consumption transport items. Awesome find, thanks for sharing.

Smart Cities Can Weather a Storm

Hurricane Harvey drenched Texas in August, Irma wreaked havoc in the Caribbean and Florida during September, and in October the United States also had major fire storms that burned in Northern California.  As usual, the media fills their audience with scenes of flooded streets, shelters crowded with people, and shows devastation to people, places, and things.  Where is this all going?  “We need to recognize it will be a new normal, a new and different normal for this entire region,” said Texas Governor Greg Abbot, when asked what the future of storms for cities looks like it will be in years to come.

Smart cities and the keys are held not by positions of politics, as they used to be in the past, in the years to come those will be held by those with the ability to advance plan for and swiftly recover.  On a practical level this often has ties to restoring electricity for those who’ve lost it are the citizens of the smart cities.  Without power efforts to return to normal are slow and often fail to deliver.  Electricity loss makes it impossible for those hit by a storm to normalize and in turn their economic occupations are also put at risk so this is an essential element of resiliency planning and ensuring sustainable futures for those residing in cities.

The primary sustainability problem is how to best plan for a disaster.  Often the focus is on recovery only and in the best of circumstances there are resources allocated to solve challenges caused by disasters, figuring how to best shelter people, fix power outages, etc..  These are reactive in nature and for some time now the trend has been to be proactive.  This is what a smart cities needs to do and in regards to electricity this means establishing grid resiliency is the place to start.  Creating infrastructure and deploying technology solutions in advance of pending storms or disasters assures optimal functioning of critical infrastructure and enables the city to recover quickly.

TECHNOLOGY ELEMENTS IN GRID RESILIENCY MASTER PLANS:

  • Self-Healing Grids
    • Identifies failing sections of the electric network, isolates, and reroutes power
  • Sensors and “Smart Switches”
    • Monitors the grid system and redirects power where needs are optimal
  • Microgrids
    • Smaller power systems that integrate with the grid or work independently

Technologies such as these involve many stakeholders – municipal planners, electricity utilities, technology providers, manufacturers of smart grid equipment, and of course the consumers or users of the electricity (just to name a few).  Large “top down” and master planned systems and their distribution approach the challenges in a way that causes different players to be involved coming from one direction while microgrids work from the opposite direction – consumers to utility as opposed to utility to consumers.  This is a fundamental issue in advance that a smart city needs to accommodate for and that stakeholder process and engagement in itself demonstrates the core value of the smart city.  The technology and the outcomes are secondary, albeit critical.

In establishing a smart city that is prepared to weather a storm in a sustainable way the first thing that needs to be done is develop a feasibility plan, especially when opting to incorporate microgrid technologies.  The next most important thing to do is establish areas of highest priority for power need (hospitals, fire departments, shelters, etc).  This is not simple nor trivial in importance.  For example, when Hurricane Sandy impacted New York City one community that was lucky and to not become devastated was the Hunts Point Market area, in the Bronx.  This area is home to one of the largest food distribution centers in the world and yet there is no microgrid and integrated planning in place to ensure it remains without fault.

In fact, to further this concern, Hunts Point is the gateway to nearly 60% of New York City’s food.  Had electricity been cut off, tons of food would have spoiled, distribution would have been crippled, and millions could have gone hungry.  Establishing feasibility is critical and defining, agreeing, and engaging in priorities with public involvement and the stakeholders is needed well in advance.  Also, even if a smart city can decide on priorities for power requirements it doesn’t mean it can address the issues of financing.  Public-private operations in themselves are significantly complex to negotiate and there is a massive difference in solutions solely run through the utility or a private enterprise endeavor.  In fact, more critical to this is the policy and regulation matters that drive these concerns for even those vary greatly throughout the United States and the pricing models established for ratepayers are far from uniform.  Everywhere it makes sense for a city to ponder these matters and aspire to smart but when considering the use of modern technologies to weather the storms that assuredly to come it means there is no better time than the present to get plans in order.

 

JMB2408 COMMENT TO ANOTHER BLOG POST (Instantly Rechargeable Batteries…a Game-changer for Electric Vehicles!):

You’ve hit most of the big bit bullet points in terms of the inhibitors that stop people from getting into an electric vehicle and buying. There is no doubt the charging infrastructure is an issue and has been used as an excuse for a long time now. If this technology can deliver, then it would be a game changer BUT it won’t address the other big problem – range anxiety – unless it really is nearly as fast as a fill up.

A lot of the “smart city” solutions are hitting the VW settlement funds to roll out chargers (think EVgo – https://www.evgo.com) and that can only work for so long. It’s exciting to see a push for technologies like this but it points to the bigger problem, who pays? If a gas station business model then this works fine as it’s just another pump, but if it’s a whole new set of infrastructure this is an issue that no city is prepared to manage well, especially one as large as New York City.

Thanks for sharing, cool work here!

Smart Cities & Off-Grid Energy Storage Systems

“Reliable Power Day and Night,” that’s what a Tesla Energy residential energy battery storage solution promises.  For better and worse, the Tesla Powerwall is no longer just for the few seeking off-grid energy storage systems and want to mitigate against utility outages.  In fact, smart energy offerings such as this are well beyond the top branded Tesla EnergySunrun launched their BrightBox solar-plus-storage product offering, Orison audaciously funded a home storage product through a Kickstarter campaign, and even the old school engineering firms such as Lockheed Martin have taken a foray into the energy management and storage market.

From a citywide sustainability perspective these solutions support the growing public desires to reduce dependency on fossil fuel burning energy sources so we should be pleased these technologies have emerged.  Thing is, their capacities to deliver beyond green washing are vast and actually executing this at scale requires sophisticated regulatory and infrastructure coordination, not to mention a whole other set of technologies for load balancing.  Scaling such offering at a citywide level, well, that’s even more complicated.  Yes, this is what a smart cities should be doing to ride the wave of consumer demand that has gone beyond the need to build a bug out shelter for the next Zombie Apocalypse but integrating solar or renewable energy systems such as wind with battery storage is unfortunately a wicked problem.  In executing these CO2 reducing and intelligent energy management solutions there are significant secondary outcomes.  At the top of the list is the challenge of dealing with the historically denoted “consumer,”  that in the process become a producer.  Hands together now, let’s welcome the prosumer to the stage; the true problem child for energy utilities!

How does an electric utility (one only ever known to sell energy) deal with this new bread called a prosumer?  If all producers install off-grid energy storage systems, what is the new role and responsibility for an electric utility?  In this position, can they garner sufficient income to pay for the maintenance of wires and poles?

To solve these challenges there must be significant regulatory involvement in advance of the transition.  Equipment manufacturers and system integrators also need to find ways to make commercially viable solutions that capitalize on consumer demand, but do so in a way so as to not send out a cry and in turn initiate a utility death spiral; ultimately leaving those without an ability to participate in this new energy marketplace footing the bill for the the entire delivery system.  Lastly, through smaller scale pilot projects all the stakeholders can work out best in class methodologies that will take us from where we are to where we clearly are going.

Thankfully, innovative energy marketplaces and regulators are seeing themselves as critical catalysts and the stakeholders in this new world of distributed energy resources (DERs) are stepping up on a global scale.  Pilot projects have begun and successes through public-private partnerships are happening.  The 2016 Southern California Edison and Tesla unveiling of the world’s largest energy storage facility and the New York City program called NY REV have led the way.  Each is but a portion of larger deployment plans for grid-connected storage batteries and both seek to reduce fossil-fuel reliance.  Comprehensive energy strategies initiated in this way will be a win-win for the utilities that want to defray the costs of replacing peakers plants reaching retirement age and for the prosumer wanting to help reduce CO2 emitting fuel in the energy mix.

 

thoughts on “Internet of Trees – When You Give a Tree an Email Address”

  1. Wow, this is really creative! It makes the trees “come alive” and is pretty amazing for potential in many ways to come. I can only begin to imagine how many other things could be categorized and brought into the electronic fold this way. I’m not sure the value of the email as a form of representation and would like to see that stepped up a bit but it’s a start. Surely the more things in cities get tagged the future will show geocaching is not just for those that are high tech in nature.
