EV Charging in 15 Seconds?

EV Charging in 15 Seconds?

An interesting but misleading claim.  Estonia-based Skeleton Technologies has announced with a flourish that it has a graphene-based ultracapacitor for EVs.  Because ultracapacitors accumulate static charges rather than store chemical energy, they do indeed recharge fast.  But they store very little energy.  So what Skeleton is saying is that with their package of graphene ultracaps and regular Lithium-ion batteries, they have a system that can accept enough charge in 5 seconds to allow someone to drive an additional 20 miles or so, rather than waiting for a more extensive charge-up.  This is not a new idea, and is consistent with Tesla having acquired ultracap manufacturer Maxwell, presumably to come up with a similar advance.  What is new is that a graphene ultracap is likely lower cost and higher capacity than the other ultracaps on the market.
Ultracaps, quite apart from making a rapid charge from an external charger possible, also extend EV range in another way.  Regenerative braking flows power back to the battery pack, but only about 20% is useful since a battery string cannot accept all the energy when it is delivered so fast.  Ultracaps would be able to store most of the energy from regen braking, and consequently, add a few miles to the range.  Clever.
You should expect to see more hybrid products like this.  In fact, this is one course that DAE Tech in Davis has taken for its new products.

Emerging Opportunities Discussion with V. John White, Exec Director of CEERT

Emerging Opportunities Discussion with V. John White, Exec Director of CEERT

We recently had the pleasure of interviewing V. John White, the 30-year veteran Executive Director of the Center for Energy Efficiency and Renewable Technology (CEERT).  CEERT has been in the lead on many of the regulatory and legislative changes that have pushed clean tech forward in the state, really a remarkable record.  Check them out at www.ceert.org.  
We talked about new frontiers in incentives and rule changes in the clean tech markets which give insight into where startups may want to be focusing their efforts.  We talked about more sophisticated demand management, the role of CCAs, the rise of the “Distribution System Operator” as an organization to deal with the complexities of local procurement, and the need for more ways to match supply and demand.  It was a great session, and one we will likely continue in the future.

SMUD on Guard

SMUD on Guard

Cybersecurity is big in the energy industry.  The Department of Homeland Security identifies the energy sector as part of the United States’ critical infrastructure. Its assets, systems, and networks are considered so vital to the United States that their incapacitation or destruction would have a debilitating effect. Clean energy would be affected as would utilities like the Sacramento Municipal Utility District (SMUD),

The question of our nation’s security has been raised on multiple occasions. Because of its importance, I spoke with Antiwon Jacobs, SMUD’s Director of Cybersecurity and Chief Information Security Officer, to learn more about the importance of cybersecurity and how it might impact entrepreneurs in clean energy. There are many forms of security that SMUD finds important to which includes but is not limited to data security, supply chain security, and infrastructure security.

When it comes to new technologies SMUD works hard to make sure that all of their customers receive only the best, thus when new technologies come around they vet them carefully so they are compliant with all regulations. Companies must ensure they are compliant, especially if they are on SMUD’s side of the meter. All technologies are analyzed and reviewed to ensure they are compliant with not only SMUD’s security standard but also other relevant regulations. Companies that want to work with SMUD should visit their website-based procurement page, some small businesses can find additional assistance through SMUD’s SEED Program

In order to effectively prevent attacks from foreign adversaries, Director Jacobs highlighted how and why security is so important and why he and other SMUD department directors are also tasked with making sure security is a priority..  For example, SMUD’s supply chain and SMUD’s Director of Procurement consistently focus on making sure the supply chain and infrastructure is secure.  Following directives from the federal government, SMUD takes the necessary steps and actions to make certain the utility and its customers are safe from attacks on the electrical grid.

CEC’s EPIC forum goes virtual

CEC’s EPIC forum goes virtual

 

The annual EPIC forum is one of the best places to hear about what the California Energy Commission is doing with its $130 million in Electric Program Investment Charge funding. Historically everyone would converge on Sacramento for a convention bringing together a diverse set of industry leaders to share best practices, learn about emerging technology, and connect about future projects and partnerships.

You can read about how 2019 and 2018 went and see how much they impacted the future.

Now it has gone online.  You can register here. They are focusing on having several break-out discussion sessions to capture that networking feeling. Join in on September 2-3 for the first virtual CEC EPIC Forum to explore strategies to achieve zero net carbon in the built environment.

The lightning talks look exciting with several of our regional companies participating. Attendees will explore exciting industry advancements, learn what challenges exist in scaling them, and opportunities California and businesses can pursue to accelerate building decarbonization across all communities. As you register you can learn more about the agenda.

California’s goal to reach carbon neutrality in the energy sector by 2045 is a challenge that brings a unique opportunity to reimagine everything. This year the EPIC forum looks at carbon neutrality in new and existing building development. Using advanced technologies, new practices in architecture and construction, enhanced load flexibility, and incorporating innovative policy and financing models, California’s innovators are developing the blueprint to create super-efficient, all-electric buildings powered primarily by onsite renewable energy and capable of supporting the larger electric grid.

The EPIC Virtual Forum features, panels, breakouts, networking, and virtual exhibits.  If that excites you and you want to join the future, register here.

Local E-bikes Tantalize Big Crowd

Local E-bikes Tantalize Big Crowd

At our meetup on June 30, 51 people joined a discussion of some of the coolest electric bikes around.  Chris Wiggins, presented the latest models in the ten-year evolution of his Glide Cruisers.  His approach is to create a premium stand-up fat-tire scooter.He distinguishes this from the numerous inexpensive sit-down scooters available, vehicles he thinks provide poor performance.  Riding his Glide Cruisers is very simple and intuitive.  Most people master it within 30 feet on their first ride.  I have tried it and can tell you it’s really fun.  He has upgraded various components and now has a detachable battery pack that makes recharging easy.  His range is about 25 miles.  These are not commuter vehicles.  They are neighborhood and shopping vehicles.

One new offering from Chris is Glidesdale Tours.  He supplies a package of cruisers to those who want to start a tour business.  One is operating now in Calistoga visiting 4 wineries.  More are on the way. He also has beefed-up versions for police departments.  They have been very popular, but hard to sell in the current climate on where police department budgets are allocated. His price tags range from $2850 to $3995 for his most popular 1000 watt and 2000 watt (48 V) models, down considerably from before.  He does have a “ludicrous” 3000 watt (96 V) version at $5850 that can reach speeds of 40 mph.  Even Chris is scared by that one, but it does have a following.  

Marrs Cycles

Kacy Marrs of Marrs Cycles presented his gorgeous sit-down e-motor cycles.  These are intended for highway use.  They look a lot like racing bikes, revealing Kacy’s background and first love.  He has hand-built some one-offs for celebrities and is not really ready for production.  He is still tinkering with the design.  He uses hub motors with the battery box and electronics between the rider’s feet.  This provides a very low center of gravity.  The whole machine weighs 210 pounds, so it is like a serious motorcycle.  Not a toy.  

One clever idea is to put a cargo basket on top of the battery box, and between the rider’s legs.  My experience is that putting a grocery bag on the back or front of a regular non-electric bike creates a lot of instability.  Too high up.  Too much of a tendency to tip over at low speeds.  I like Kacy’s idea even though at first it seems odd.  

Kacy sees his standard bike as costing in the $5-6,000 range in production, with a 60-mile or so range.  That leads to the question of where to park it at a destination to recharge it.  Don’t need much more than a 110 V outlet.  Any clever innovators out there that want to tackle this? 

Kacy is clearly targeting a specialized market.  His product is like the original Tesla Roadster—pricey but attractive to those wanting a beautiful performance machine.  

Our presenter from Rumble Motors was a no-show, but we did talk about what they told us in preparation for the night.  Rumble started with a pretty aggressive e-motorcycle (the one in WestWorld), but it is betting its future on a more modest product, the Rumble Air.  It would be priced at $3,450 as a commuter and delivery bike with a 60-mile range.  It is a lightweight open frame, using a hub motor (rather than a motor between the rider’s feet) and a battery pack in the frame.  They are in the process of moving manufacturing into a Sacramento site that will serve the Western Hemisphere while maintaining their current site in Sweden to serve the European market.  Their immediate goal is to reach a combined production of 2600 bikes per year.   To date they have built and delivered 200 of the earlier models.  They have some good videos on their website that are worth a look
