Siemens eHighway for Hybrid EV Trucks + Ethane—This could be a winning combo!

Many in the energy industry know and there is a great deal chatter now these days that a replacement transportation fuel is needed, until the electrical vehicle infrastructure can become more fully realized. I think those in charge are solicitous about adopting an unconventional fuel stock, because so many green fashionistas have undermined the science in the biofuels sector for so many years, too. Unfortunately, there is going to be A LOT of pain, soon. The price of gasoline is low for a reason–we have reached the end of growth. If consumers cannot afford to buy goods and services, there will be little demand, so prices have to be kept low. This is the antithesis of the ‘models’ predictions of economists from years gone by.

This past Friday, the DoE rejected my and my co-collaborator’s Concept paper for their Dual Fuel Fleet Demonstration Project, altho they agreed to recognize, consider ethane as a transportation fuel stock now. EV (Electric Vehicle) was featured prominently in the categorical exclusion criteria scope and their scoring. No surprises. Big auto companies who are trying to get more hybrid-EV drivetrains for trucks, and SUVs into the market are trying to squeeze out any competition, so the (mostly) energy illiterate, entitled masses who lifestyles predicated on hyper-consumerism can continue. This hyper-consumerism lifestyle is NOT sustainable.

This is a DAMN pity. Such hubris. Such stupidity and short-sightedness. Any sensible engineer knows, until batteries and electric motors weigh the same/less, a dense, energy-rich, liquid fuel makes the most sense.  At worst, an intermediate, transitional fuel solution, like ethane is needed–that is if the citizenry is hell-bent on maintaining this quality of life to which they have become accustomed. 

I mean, what, we here in the USA are INSTANTLY going to get an EV infrastructure built?! What emulate Europe’s train/locomotive system, because we were short-sighted back in the day to mostly abandon this for the automobile, which is now going to bite us more in the ass? Sure. How long will this take? At least a decade+, at best. So what about the interim?

I bet the handlers of the engineers who have performed calculations how much space carrying today’s batteries on a semi-truck will take up have been excoriated or ignored. What ~½+ the payload?

Siemens is proposing an EV highway, the eHighway in SoCal for semi-trucks/18-wheelers; results to be reported next summer. However, the question that requires answering is how much power these hybrid-EV trucks will need to overcome to compete with 1,500 lb of diesel in a typical semi-/18-wheeler fuel tank. 

Siemen’s EV Truck

I attempted to locate information on Siemen’s web site with road freight challenges metrics that have to be overcome; there was this:

The main obstacle to electrified road freight has been the size and weight required for on-board storage of electrical energy. For example, a road truck weighing 40 tons traveling 1,000 kilometers would need approximately 20 tons of batteries. This problem can be solved by providing power to the truck as it is driving.

So at least my initial W.A.G. (wild ass guess) about batteries taking up ~½ load was correct. NOT even cost effective today. Let alone all the interstate weight restrictions that would be violated hauling around massive battery packs. It’s not as if the roadway infrastructure isn’t already under maintained, tenuous.  And if there’s no gas tax, then where’s the money going to come from to keep this infrastructure viable, working?!! Is anyone talking about this?! No. Ugh.

I mean, at least delivery companies like UPS get that to get to a point where an EV infrastructure makes sense is to have a hybrid solution, first. Crimey, a fully electrical drivetrain, with a simple gearbox, smaller battery, regenerative braking, and an electrical generator optimized for certain speeds and driving behavior, er like a delivery truck driver in a major metro area. Ethane could be the complementary, supplementary fuel stock for these hybrid-EV trucks, in the interim and perhaps well into the future. I’m just sayin’…

Crimey! MORE Green Going Wrong | Ford to install wind and solar energy at dealerships

[HUGE SIGH]

I just caught this today.

Ford to install wind and solar energy at dealerships


I couldn’t let this one go. Another installation of kinetic architecture. And so, blatted out the following on this post…

[POST #1]

I’m fairly certain the PV arrays will be the stars of producing the flow of electrons. And unless the wind turbines have been sited correctly, they will only be kinetic architecture ==> another green gone wrong installation by green fashionistas Wind Energy Corporation.

[POST #2]

As someone who performed post-graduate research of the performance of small wind turbines in the built environment, this installation is questionable at best. And just based on the photo, I’m pretty sure this installation was not sited well, which only gives small wind a bad name.

I also went to the vendor’s,  Wind Energy Corporation’s web site, and all I could locate was a single landing page. Red flag #1. I also searched for Jack Phillips on Linkedin and his background is only in accounting and int’l business, NOT computational fluid dynamics or mechanical engineering. Red flag #2.

Vertical Axis Wind Turbines (VAWTs) like the ones here, are NOT immune to turbulence. Rapid, turbulent low-level wind increases the fatigue on a VAWT just like an Horizontal Axis Wind Turbines (HAWTs). HAWTs are just as sensitive to changing wind direction and turbulence as VAWTs, especially if the turbine is installed on too short a tower.

Readers to this post should also know:

  • VAWTs perform better if they too are mounted higher in smoothest, strongest wind, not near to the ground or close to the tops of buildings or other structures, natural canopies.
  • VAWTs blades are prone to fatigue created by centrifugal forces as the blades spin around the central axis –> they are less reliable  than HAWTs.
  • VAWTs require large bearings at the tower top to permit the shaft to rotate and thick steel cable to supper them –> more costly, especially when repairs and maintenance are needed.
  • VAWTs are less reliable and less efficient that HAWTs, and made worse if they are mounted at ground level or on top of buildings. And the ones in this photo are clearly close to ground level.

Reference: Power from the Wind by Dan Chiras with contributions from Mick Sagrillo and Ian Woofenden.

It is a well-known fact that, by seasoned professional small wind turbine experts, VAWTs, like these are less efficient than HAWTs  and made worse by being mounted closer to ground level boundary level–the few advantages they offer cannot counter the many, fatal disadvantages sited so close to ground level.

Small wind turbine installations are not advised that do not meet the  best practices recommendation of at least 30 feet above the closest obstacle, er trees included, within 500 feet, and are well inside the turbulence bubble (vertically ~2xs the height of the obstruction/house(s) and downwind ~15x – 20x the height of the obstruction/house(s)). Raising a wind turbine, be it HAWT or VAWT,  into the smoothest, strongest wind ensures greater electrical production and longer machine life.

I would also encourage readers to focus more on the performance data vs power curve information. I realize that rated power of wind turbines/power curves was devised to provide customers a way to compare wind turbines. I think folks need to understand that its usefulness has been limited. After taking another look (since it was back in 2009 that I looked into performance data from the results of the Warwick Wind Trials), I see updated standards in the wind industry for determining rated power has been established for comparison across models i.e. 5 m/s [11 mph].

Perhaps the editor, James Murray will revisit this read and ensure the truth is told about this well-intended offering. Not holding my breath, especially because they keep deleting my posts. Yeah, well, you know…Fleh.

Micro-grid-as-a-service

Wonders never cease. Quality takes time.

At least now that CA SB 43 is being realized, thanks to Governor Jerry Brown signing it into law back on 28 September 2013, some are taking notice an opportunity to explore developing decentralized, utility-scale hybrid renewable energy systems technologies [and not just solar only] on existing electrical distribution networks in the urban/built environment in N. California. And what’s particularly great about this law is, 100 MW of the 600 MW needs to be developed in under-represented, marginalized communities.

The Germans persist in being the vanguards in this arena of distributed generation (DG). Just have a look at the following read:

Integrating Variable Renewables as Germany Expands Its Grid 

SDG&E’s Borrego Springs real-world micro-grid performed well during a severe weather storm that affected 2780 customers power outage due to a severe storm on 6 Sept 2013. I understand this was one of the first times in the USA that a micro-grid in the actual working environment, and not just a model, has been used to power a large portion of a community during an emergency situation.

  • uses new smart grid technology – including local power generation, local energy storage, and automated switching
  • variances to island are in place for emergency scenarios
  • 1060 customers power restored in a few hours
  • All 2780 customers power restored w/in 25 hours

I have some enquiries to SDG&E, and am awaiting feedback on the following–which I will update on this thread, once received:

  • RE systems technologies deployed
  • Performance metrics

A break-off from a group I have been volunteering for, has been brainstorming on how to make this a reality in the SF East Bay Area. For now, our progress can be followed, here.

I have said for many, many years, it just makes sense to generate energy closer to where it will be utilized. And once the IT, smart(er) grid communications protocol ‘glue’ is implemented and tuned, we’ll be off to the races. And this is just one version of the future outlook:

Plan F :: I lament — Wondering if and when the Hybrid Renewable Energy Engineer job description will become a norm…

Some wonder why I persist in having such a difficult time landing work as a hybrid renewable energy engineer. Perhaps if I were of the business developer, marketing, sales or policy ilk, I’d have more work than I knew what to do with. But I am an R&D anomaly and not readily embraced. So, I need to continue to try to be patient to let people catch up.

One of my colleagues/mentors, the notable, internationally recognized renewable energy sage Paul Gipe shared the following affirmation with me several weeks ago about my attempt to heighten awareness about why community wind is needed at the LCEA Clean Power, Healthy Communities Conference in Oakland, CA. My presentation is here, but sadly, there was only a single party interested in my offering during the conference. Paul emailed me the following after the conference:

Subject: hang in there/you did good

Date: October 18, 2013 7:03:09 AM PDT

To: Kimberly King <kimgerly@kimgerly.com>

hang in there kimberly. you did the right thing by coming out and making a presentation before the “solar only” crowd. it needed to be done, needs to be done, and needs to be done again and again–americans are slow learners.

but of course part of the problem is that we don’t have any policies that make it possible–and until we do we’ll just be working at the margins. . .

paul

Yes, I have been on the margins since I embarked on this reinvention to become a hybrid renewable energy engineer back in 2001. And back then, I knew distributed generation would eventually become the order of the day. Thanks to SB 43 there is a smidgen of traction, but it’s still no slam dunk. Not to mention, I have touted distributed energy in the Interests section of my LinkedIn profile when I first launched my profile back in 2005http://www.linkedin.com/in/kimgerly

To obtain a challenging position developing hybrid renewable energy systems using sustainable development practices. Research and engineer hybrid renewable energy power micro-grid/nano-grid systems. Research mitigating noise generated by small wind turbines in the built environment. Make contributions developing hybrid renewable distributed energy power systems toward the development of renewable energy as part of the World Wide Energy Web. Engineer renewable energy efficiency designs.

It was because of my time holding leadership roles, developing solutions to problems in unknown territory, my capabilities as a Jill-of-all-trades generalist during the dot-com in IT/Systems Engineering/Administration, that Silver Spring Networks | UH-HNEI | DoE SunShot Initiative SmartGrid PV Inverter Project picked me up last year for a short-term, six month contract as a technical writer. One of the big reasons I was selected was due to my load flow analysis embedding ten wind turbine generators on an existing electrical distribution network paper as a part of my post-graduate degree. Mind you, this SunShot Initiative project is the cornerstone, benchmark communications protocol project for the USA for embedding a high-penetration of residential PV inverters on existing electrical distribution networks. This pilot’s aims are to discern how well the bi-directional flow of electrons from renewable energy generators can be managed by a utility. Most of the people I worked with on this project are ex-Cisco engineers, and found me to be a natural for this job. The reference letter from my supervisor is viewable here.

I was also in the queue for consideration under the Fraunhofer Institute/Sandia National Labs Micro-grid/Nano-grid project collaboration that was tabled indefinitely late last year. Thank you gov’t shutdown. *Sigh* And just a couple of months ago, I was in the queue to work on Chevron Energy Solutions/Chevron Renewable Power Division as a Investment Structuring Analyst/Associate for PV and geothermal plants, but these projects were placed on hold indefinitely as a result of the government shutdown.

Unfortunately, as time progresses, I feel more and more like hedged my bets incorrectly–thinking by now the renewable energy industry would have adopted the mindset that was pervasive during the dot-com to seek agile, adaptable engineers who are agitators, and who can wear more than one hat to get a job completed. Instead, this myopic vision I have come to witness over the past eight years seems to be the order of the day. This is out of my control. And so, I continue to be relegated to the margins/fringes. I am all for contingency planning. Sure always having a Plan B or Plan C makes sense, but I NEVER fathomed I’d need a Plan F. Let’s see how this all came about…

Plan AStarting in 2001, I volunteered at the Resource Renewable Institute, to learn more about this operatives renewable energy and sustainable development. I also performed due diligence for The Rahus Institute on why more PV systems were not being installed on K-12 schools in California. From 2004-2010, pursued academic coursework at a veritable plethora of universities in the USA, The Netherlands and the UK. I also completed PV Design and Installation coursework with Solar Energy International and at Diablo Valley College. For a year, I helped design and install solar PV systems on residences.  Eventually completed a post-graduate degree in renewable energy systems technology engineering in 2010 at the Centre for Renewable Energy Systems Technology (CREST) a part of Loughborough Technical University in the Midlands of the UK.

Plan BDue to the tumultuous, global financial climate in 2008, started having to fall back on my technical writing, computer science skills set–just like a number of my seasoned, professional CREST classmates had to do. Made the short list a number of times for a number of jobs–I lost count awhile ago. Chemistry. However, it’s an employers’ market and one has to meet 100% of the job description ‘check-box’ criteria, and getting past the HR ‘gate keepers’ these past few years has been inordinately challenging.

Plan C Started falling back on my chef skills as an Eco-chef; swapping my services for short-term housing, if pay was an issue.

Plan DDog sitting, House sitting to make trickle-in survival income while waiting for contractual engineering work to be finalized. These contracts never materialized.

Plan EJoined the SF Local 16 to obtain part-time freelance work in audio and visual realm, in an effort to get off the ‘food stamp diet.’

Plan F – My present aim is to secure a certificate in Industrial Maintenance [welding, machining, hydraulics] at Laney College, because our first world nation with a third world infrastructure is going to break HARD, and it will require having more talent who not only knows how to design, but also knows how to fix and tune, on-the-fly in the field.

I have some appointments coming up in December to chat with a CPUC [California Public Utilities Commissioner] to discuss why there persists in being consternation with supplier diversity issues. Also, more recently, a finance director at Chevron Energy Solutions has expressed some interest in hearing my ideas on how Chevron might participate in SB 43.

I am no Nikola Tesla, but I certainly have a great deal of empathy for the man, his vision and all the ‘brick walls’ he had to traverse to even get his ideas and designs embraced. Sadly, he was impoverished and in debt when he passed away. Alas…

To quote Randy Pausch,

I sure hope so, because I’m borderline vanquished.

An elegant solution for a problem during extreme weather events — small wind turbines

It’s just an idea. A great deal of small wind turbine generators can withstand  Category 1 hurricane wind speeds. [Citation: Saffir-Simpson hurricane scale]

There are, however, some small wind turbine generators installed on the Boston-Cambridge Museum of Science back in 2009 that have survival wind speeds of up to 155+mph (Category 4):

  • Mariah Power Windspire – survival wind speed – 105 mph | 47 m/s (Falls w/in the Category 2 range)
  • Cascade Engineering Swift – maximum designed wind speed – 145 mph | 64.8 m/s (Falls w/in the Category 4 range)
  • AeroVironment AVX1000 – designed to withstand 120 mph winds — good for low-aspect ratio structures (Falls w/in the Category 3 range)
  • The Proven 6 – cut-out wind speed –  >155 mph | >70 metres/second (Falls w/in the Category 4+ range)
  • Southwest Windpower SkyStream 3.7 – survival wind speed – 140 mph | 63 m/s  (Falls w/in the Category 4 range)

I wondered how they faired during Hurricane Sandy? Yes, I have made an enquiry and am awaiting a reply.

Hurricane Sandy caused some hospitals in NYC to evacuate patients, because their diesel gensets ran out of fuel. This should have NEVER happened if the hospital administrators planned better for contingencies.

Perhaps if they had had some properly designed and sited small wind turbines and PV arrays, er hybrid renewable energy systems, installed on the rooftops, coupled with back up batteries to capitalize on the indifferent forces of Mother Nature, there would not have been a need to relocate all those patients. Of course, I am not sure if this would be a pragmatic solution, since this is all contingent on the extent of the load requirements and if the wind turbines can withstand hurricane force wind. In general, I think generating electricity closer to where it will be used is a way to go, and smaller hybrid renewable energy systems is better–especially systems that can be deployed quickly and disassembled quickly.

I rather like one of my colleague’s designs, the AVX-1000, that is best sited on low aspect ratio buildings to capture the chimney effect of wind coming up the side of a building. When it’s not ‘hurricane season’ these stylish machines, should not draw as much ire from NIMBYs.

In a disaster scenario, I think implementing wind turbine generators (WTGs) is particularly elegant way to go–this turns a problem into a solution. Sure, perhaps in most locations in a city, small WTGs are not pragmatic because of all the roughness. This, however, could be the exact reason why small WTGs in the built environment can be added to the equation. When power is lost, wind is a direct or indirect cause, so there is plenty of energy for the taking, sun or no sun…

If I get a ‘moment’, or as soon as I can obtain all the pertinent data I require, I’ll post up a cost-comparison analysis of what it would cost to install a small, hybrid renewable energy system on these hospitals and compare this to a guestimated cost of what was spent to evacuate and relocate the ~1,000 patients from NYU Langone Medical Center and Bellevue Hospital Center during Hurricane Sandy. Ja, I’m a hope addict…

PREPARE. RESPOND. ADAPT.

Just how well did RE systems fair during Hurricane Sandy?

As much as I would like to believe renewable energy technologies faired better than conventional power plants during Hurricane Sandy, my sentiments are guarded. On a technology sector web site to which I subscribed, there was a prudent question raised, “What happens when we have two disasters at once?” Or for that matter, what happens if there are more than three, four, … disasters?

Hurricane Sandy Uncovers Strength and Simplicity of Renewable Energy Systems

As much as  this Hope Addict  would like to think larger, static renewable energy systems will fair better than traditional power plants, I can’t help but think they too will be compromised after natural disasters–but to what extent, this remains to be seen. I think because the solar technologies have a faster innovation cycle, measures for decommissioning and recommissioning during disaster events, as well as deploying more distributed generation hybrid micro-/nano-grid systems that are smaller and more modular should be looked at where future contingency criteria and planning is concerned.

As I stated in a previous post, we cannot overlook the indifference and indisputable bidding of Mother Nature that will certainly continue to dictate. I accept what this will ultimately be. But the wise choice is to be prepared, adapt and control or eliminate whatever human actions, that we know beyond a reasonable doubt, are affecting the change that will ultimately ‘inconvenience’ many. We also need to acknowledge that the Earth and all its subsystems is a highly dynamic and changing place, and not to be controlled, but rather respected. Hopefully, the language of systemic causation will feature the operatives climate instability into the discussion more prominently.

Nothing short of a planet wrecking speech… & Pippa drops some science

Mitt Romney’s presidential nomination acceptance speech was nothing shore of a planet wrecking speech.’ Energy independence by CONG (coal oil nooklar natural gas).’ Please. A single mention of renewables does not equate to support for renewables. Poking more holes in our spaceship, anthropogenically exacerbating this climate instability, because of the wanton, satiation addiction to oil?! Not a good idea.

This climate instability positive feedback loop is in full effect. Have a look at the following image on the Arctic Sea Ice Extent. Grim.

Arctic Sea Ice Extent

Not sure what we’re doing will be enough, AT ALL, to force a feedback. We need to stop emitting post haste, not drilling.

I’d like to see some politico comprehend and understand that investing substantively in the world wide energy web ‘paved road’ for communications infrastructure is worthwhile, so we can actually intelligently and efficiently manage the flow of electrons needed for electrification and ‘hot water’ heating in the USA–silly Americans. I mean, a great deal of what needs to be done requires A LOT of systems engineering. This might actually get our RE industry somewhere, enabling more conservation, and change in human behavior to be mindful, instead of trying to piecemeal singular RE technology solutions together.

We need more support for R&D and implementation of hybrid RE systems on existing distribution networks, and support for storage in the USA, so we can match explosive results of say, the likes of Germany–they installed 3MW of PV alone in December 2011. “…the nation’s PV installations fed 22 gigawatts of electricity into the grid at one point, providing nearly half of the country’s energy needs.”

Now, that’s explosive!

Ancillary aside: Pippa drops some science. Arctic Ice Shelf measures 4km^2 = smallest coverage in recorded history. Bigger than India.

What is a Hybrid RE Engineer?

An engineering generalist with an understanding of sustainable development whose skills set are typically comprised of an amalgam of mechanical and electrical engineering. One who is able to design and assemble systems and components that are comprised of more than one renewable energy (RE) technology i.e. solar, wind, hydro-kinetic (ocean/wave/micro-hydro), biomass, hydrogen fuel cell, geothermal and storage (battery, fly wheel, pumped-hydro). The RE technologies selected depend on one's geographical predisposition, resource availability, the end-use need, practicing conservation (behavioral change) to name a few considerations...
