Nano-Storage, the Store-Gen Grid and Hurricane Ike

Hurricane Ike has given us a massive object lesson on the importance of implementing the late Rick Smalley’s vision of the Store-Gen Grid (SGG; graphic courtesy Wade Adams at Rice’s Smalley Institute) – a highly distributed network of granular electric production and storage.  One of the elements of the SGG concept is a household storage unit for about 100 kW-hrs of dispatch energy. 

 Smalley's Store-Gen Grid Concept Could Keep The Lights on After a Hurricane

Well, we ain’t there yet.  Of all the standard infrastructure services, only two seem to be reliable in a pinch: cell phones and natural gas.  The electric grid is plainly extremely fragile.  This is a major opportunity for nanotechnology.  With a major power outage in the energy capital of the world, this topic ought to get *lot* more traction, and fast.  So get your thinking caps on.  According to the Houston Chronicle, nearly 3 million people lost power due to the storm.  So I reckon there are about 3 million ready customers for the next big thing in distributed power.  I’m one of them!

 

Now, when considering storage technologies, energy density *really* matters!  Among practical materials, nothing is even comes close to gasoline or diesel fuel.  Just before the storm, my wife was wise enough to ignore my objections and bought a neat little Honda 2kW generator.  I got ten gallons of gas on Friday, and used about five gallons over a 36 hour period.  This was just enough to keep the refrigerator going, charge cell phones, and run a lamp, two fans and a small TV set.  This enabled us to essentially camp-out in our house.  Forget about air conditioning, running the washer/dryer or taking a hot shower (the darned water heater has an electric starter).

 

Here are some representative (volumetric) storage energy densities (from Wikipedia):

 

Technology or Material

Energy Density ( MJ / liter )

Capacitor Ultracapacitor

~ 0.050

Lead acid battery             

~ 0.15

Flywheel

~ 0.50

Lithium ion battery     

~ 1.50

Hydrogen Fuel Cell 

~ 1.62

Li Ion w/ nanowires   

~ 2.60

Ethanol                 

~ 24.0

Gasoline                

~ 34.6

 

Let’s look at the Lead-Acid Battery (LAB) as an example, since it’s still the workhorse for storing electric energy.  My five gallons of gas would equate to 4,383 liters of lead-acid batteries (LABs) (3.8*5*34.6/0.15).  My total investment for generation and storage was $1020 ($1000 generator, $20 gas).  How much does 4.3 cubic meters of LABs cost again? - about $20-$50/liter?  And how much does it weigh?  I can (and did) carry (lug) the generator and the five gallons of gas myself at the same time. 

 

Overall, electrical storage energy density is worse than chemical storage a good factor of ten or more.  An order of magnitude (or two) is nothing to sneeze at!  It is plain that without sufficient oil/gasoline/diesel, we are in a world of hurt for the foreseeable future.

 

Each of the technologies listed above employs, or can be improved with, nanotechnology or nanostructured materials.  Let’s do a little math and get a handle on the nano-scale challenge involved here.  If gasoline has an energy density of, say, 35 MJ/l, it equivalently contains about 3.5 x 10-17 Joules per cubic nanometer.  Modeling this as a parallel plate capacitor in vacuum with a 1 nm gap, you get the target energy density with a voltage difference of about 2.8 Volts.  If you use a decent dielectric like TiO2 (k = 40ε0) instead of vacuum, you only need 0.44 V.  About 1 V/nm is a pretty stiff electric field, but not larger than those considered routine for ultra-thin gates in the semiconductor industry.  This all seems pretty doable; making the nanowire connections to the outside world will be the tricky part; it’s probably a job for carbon nanotubes or maybe graphene.  Rick would have liked that. 

 

I hope somebody out there gets to work on this pronto!  Even at $100 / liter, it would be a useful technology.  When you get the cost down to about $10 / liter, you’ll be a bona fide hero, and a very wealthy one at that.

Texas-Sized Nanotechnology

Dr. Howard Schmidt is a native Texan, a long-time Houston resident and a serial entrepreneur.  He grew up San Antonio and moved to Houston to attend Rice University, where he got a BS in electrical engineering in 1980, and then a Ph.D. in physical chemistry in 1986.  Since then he has been involved in four technology start-ups, including SI Diamond Technology, an early nanomaterials company that he took public in 1993.  In 2003, Dr. Schmidt joined Rick Smalley’s research team as the Executive Director of the Carbon Nanotechnology Laboratory.  Schmidt is now a Research Fellow in the Chemical and Biomolecular Engineering Department at Rice, mainly focused on developing energy-related applications of single-wall carbon nanotubes.  He also serves as Senior Nanotechnology Advisor to the Advanced Energy Consortium, and is on the board of Axion Power International. Dr. Schmidt has agreed to become a regular contributor to Startup Houston; this is his first post.

The Advanced Energy Consortium (AEC) just officially announced its first Request For Proposals (RFP). This is big news for us little (nano) people, and it seems a good topic with which to kick off a new column on nanotechnology, commercialization and start-up companies.

And it fits in nicely with my personal perspective on technology and start-ups. For me, technology is pure fun - it’s using science, engineering, imagination, persistence and a little luck to solve a problem, make something work, make some novel material, etc. But starting a company is serious stuff. There can be fun involved, of course. Watching a new company progress and grow is big fun. But you don’t start a company for fun; you start a company to make money. And money comes from customers. Customers fork over money because you and your technology solve some problem they have. Many technologists start companies because they love their technology, not because they have a customer asking them to turn pro and sell them a zillion copies of their new widget.

And that is what makes the AEC and their RFP soooo cool. It’s a collection of well funded customers that are telling us what they want to buy. The AEC sponsors include six integrated exploration and production companies (BP America Inc., ConocoPhillips, Marathon Oil Corp., Occidental Oil and Gas, Shell and Total) and three major well services companies (Baker Hughes Incorporated, Halliburton Energy Services Inc., and Schlumberger). At this point they’re looking for basic micro- and nanotechnology research and development services. Eventually, the hope is that this research will generate fieldable technologies for locating and extracting oil from known reservoirs. They’re essentially shopping for technologists that they hope to pay to develop new tools that they will eventually buy to produce oil.

In general, my expectation is that this R&D activity will spawn new materials and sensing methods; some may get used directly by the majors, but most will get bundled into a package and distributed by the service companies. A likely play for entrepreneurs is to manufacture the materials and components and then provide them to the integrating service companies. Talk about soup-to-nuts market pull!

The RFP is open to all bidders (universities, small businesses, large companies, national labs, you-name-it) world-wide, although I would have to predict that academic researchers will gain the lion’s share of the contracts. They have an advantage in cheap labor (graduate students) and extensive facilities for characterizing new materials. But something nanotechnologists usually do not have is a) a working knowledge of hydrocarbon production and b) experience at commercializing some new widget.

This makes for an important opportunity for Houston entrepreneurs. Since Houston is the energy capital of the world (right?), there are plenty of working and retired experts here in oil and gas production. Those academic researchers will be well served by teaming up with O&G experts to round out their teams via consulting or subcontracting arrangements. Similarly, if you have a killer idea, you could find academic researchers to help perform the research or characterize the materials. You can find potential partners by trolling the ‘research interests’ websites of individual profs at the local research universities, Rice and UH. UT and TAMU are not too far away to collaborate with, either. Most professors are quite approachable if you a) know what you’re talking about and b) can provide some complementary resource. They’re amazingly pressed for time, and complete experts at evaluating ideas quickly (from peer reviewing each other’s papers and proposals), so don’t take it personally if you get a ‘no’ pretty quickly. Also, keep a look out for PR coverage of breakthroughs from AEC funded research over the next year or two. They’ll also turn up at events like the Rice Alliance meetings. Those research products will need experienced entrepreneurs to make the commercial transition.

Overall, I think this bodes well for generating a number of great start-up opportunities in Houston. Happy hunting!

Rice Alliance hosts largest Business Plan Competition in the World

rice_alliance_logo_1.jpg

The Rice Alliance has gone and outdone themselves again by nearly doubling the amount of funds that will be awarded at this year’s Business Plan Competition.  They will be awarding over $600,000 dollars in funds for approximately 36 different graduate teams from around the world, which enables them to lay claim to hosting “the largest and richest intercollegiate MBA/graduate-level business plan competition in the world, with more prize money, more teams competing, and more judges than any other competition.”  (Somebody please tell me they are videotaping this thing, because I think this would make a great reality show).  Also, according to their web site, every team will receive some type of cash award so noone goes home empty handed. 

Are you a graduate team with a killer business plan?  You can still register your team by submitting your executive summary before February 21st here and you can find all of the complete details about the event here.

HTC Education Series - Raising Capital in Texas Today - Session III: Raising Funds for Growth

This past Friday morning I had the pleasure of getting out of bed early (again) to attend the Houston Technology Center’s Education Seminar Series on Raising Capital in Texas Today. Today’s session was entitled, “Raising Funds for Growth: Series B and Beyond“. The moderator for the event was Scott Crist of Aegis Texas Ventures. Our panel of experts for this seminar were:

You can read through the presentation at the link above but here is an overview of what was discussed:

  1. The three represented a nice variety of business capitalization history: venture funding (SalvageSale), self-funding (CyrusOne) and bootstrapping (Merrick Systems).
  2. Merrick Systems’ need for additional capital was to accelerate growth in both organic and new markets. Rather than look at an equity solution, Merrick Systems put together a senior credit facility with Silicon Valley Bank. This is something that many small business startups fail to look into mostly due to a lack of understanding of this segment of the market. The majority of the startups that I have been involved with were able to secure quality credit from the “venture tech banks” like Silicon Valley Bank, Comerica (through their Technology and Life Sciences team), Square1 Bank and Bridge Bank (if you need any introduction to one of these lenders, send me an email).
  3. SalvageSale’s recent financing seemed more like a leveraged MBO than growth capital, although the new investment from Spire Capital is likely a good way to both recapitalize the company and partner with a solid fund with a track record in successful buyouts.
  4. CyrusOne effectively sold the company to a private equity group but still has a very active management. Abry Partners has a history here in Houston with their purchase of Caprock back in 2006. What is nice about what Dave Ferdman did was recapitalize the existing investors and provide an infusion of additional capital to fund CyrusOne’s continued growth in data center development.

The biggest takeaway from me is how important your early rounds are in the long term outcome of the company. As in most things, the early decisions tend to have a more material impact on a company’s velocity than do the latter ones. Merrick Systems was able to grow without much of any dilutive impact and is now poised to further grow through senior debt, the second least costly capital next to public debt. SalvageSale confessed to seller’s remorse with their early stage investors but were able to break through and now have a bright road ahead of them. CyrusOne recognized that the future required deeper pockets and made an excellent decision to partner with a long term investor rather than sell out to short term needs for liquidity.

All in all, the three gentlemen were excellent presenters and provided attendees with another quality HTC educational event.

Interview with Walter Ulrich, President and CEO of the Houston Technology Center

When I first met Walter Ulrich at a Houston Technology Center event, what I gathered most about him was that this guy was the real deal: a true “pocket protector” geek in the most admiring sense of the word. Ulrich has been a pioneer in the information technology sector for almost 40 years. In the 1970’s, Ulrich led the development of the first commercially successful email service. That’s impressive.
During the 1980’s and 1990’s, Ulrich consulted with Fortune 100 company’s on technology and business issues until he became the CEO of Houston-based Mincron Software Systems. After leaving that role, Ulrich was one of two Houston technology professionals to be appointed by Texas Gov. Rick Perry to serve on the advisory committee for the $200 million Emerging Technology Fund.

I had a chance to catch up with Walter this last week; here are some excerpts from our chat:

Josh: I know that you have been in and around technology for many years. How did you come to get involved with the HTC?

Walter: The HTC looked like a place where I could give back as a volunteer, and it turned out to also be the place where much important business goes on.  As someone active in the technology world, active and deep participation in the HTC was not only personally satisfying but it is good for business.

Josh: There are all different perspectives on the HTC’s core mission. How would you characterize your vision?

Walter: We aspire to make Houston a globally recognized center of technology innovation and commercialization, particularly focused on IT and Web 2.0, energy and clean energy technologies, bio/life sciences, nanotechnology and NASA-related aerospace. We have the underlying economic strength and have been building the business infrastructure over the last ten years.  Now it is time to execute successful commercialization by driving successes one emerging company at a time.

Josh: There are many groups around town that all seem to overlap in different respects when it comes to supporting technology development and new business creation (Rice Alliance for Technology and Entrepreneurship, University of Houston Small Business Development Center, HTC, Greater Houston Partnership, Mayor’s Office). From an outsiders perspective, there does not seem to be much collaborative effort among these groups. Is this the case and if so, what can be done to have a more concerted effort to work together?

Norwegian VC Firm to Open Houston Office

Energy Ventures announced today the opening of two new offices for the firm, Aberdeen and Houston.  This Norwegian venture capital firm invests in “game changing” technologies in the upstream oil and gas markets, focused primarily on exploration and production activity.

There is some familial aspect to this announcement as well. Former president of the Houston Technology Center’s energy practice, Bob Schwartz, will be joining Energy Ventures sourcing deals for and through the HTC. Bob has been a fantastic agent of change at the HTC over the years and his presence will be missed.

Randy Woelfel has assumed the lead role in the energy group at the HTC and will be spearheading several new initiatives over the coming months.
