Ever since the ClimateGate scandal broke, I have been asked "how do we play this?" With the chaotic failure of Copenhagen, this is a more pressing question, as bets are being shuffled in cleantech with the new change of assumptions. At a high level the primary investment implications are to move out of sectors that require government subsidies or carbon taxes, and into sectors with economic competitiveness. This is not to say we won't see attempts to pass cap™ or carbon taxes, but they seem likely to give way to a different spin on cleantech, that of saving green jobs not saving the planet.
UPDATE 12/22: Also, the exuberance for CleanTech investing has abated (see chart, and note how it says cleantech investing has "surged" even as the chart shows a 50% drop this year). The WSJ ran a post-Copenhagen piece today about cleantech firms having to "reset" their strategies. They also agree with my thesis posted Dec7 of a change in the rationale to "economic development or reducing dependence on Mideast oil, [rather] than at threats posed by global warming."
With this in mind, we need to start where green technologies are or will
soon be price competitive. Casey Research has a really useful newsletter on point, and here is on of their charts:
Let's walk through major CleanTech sectors with this chart in mind.
Carbon Trading
This one is easy: stay away, stay far away. This will be a huge casualty of the failure at Copenhagen. Even as the masses assembled, Denmark was marked with a huge scandal over fraud in carbon markets. Australia's Cap & Trade bill failed on the eve of the confab. The Danish scams were in the Billions of Kroner. Now the scams are being found more broadly, across Europe. Organized crime may have skimmed an astounding 5B Euros ($7.4B).
UPDATE 12/22: This chart from the WSJ shows how carbon allowances have plunged post Copenhagen. To make carbon-free technologies like solar competitive, these allowances need to be above E60/tonne. It has fallen in half from a recent high of E25 to below E12.50. Quite a drag, says the Silicon Valley cleantech press.
Geothermal
The authors of the Casey Energy Report make a great case for geothermal. Right now geothermal is used near hotspots of surface geothermal activity. The core insight is that future technology can turn almost any area into a geothermal hotspot, providing a 24/7 energy source which has very low incremental costs once set up. No need to worry over the sun shining or the wind blowing. There is a public play here, recommended by David Fessler:
This is an area with plenty of potential, particularly in the western United States. When it comes to profitable, large-scale geothermal and recovered power producers, Ormat Technologies (NYSE: ORA) is pretty much the “Lone Ranger,” but many smaller operations will likely fire up geothermal plants in 2010.
UPDATE 12/22: the biggest setback to geothermal was a Swiss project which triggered an earthquake. There is the well-funded (pun intended) AltaRock project just north of SF, near the San Andreas fault. Local geologists seem a bit sanguine about this. Hmmm. Deep drilling and pushing pressurized water down causes small earthquakes. Why no earthquakes in oil country, where they drill deeper and also push pressurized water and Co2 down? The very structures which trap pools of oil also bury geothermal effects, and make make geothermal diseconomical; it works best where the geothermal activity is near the surface.
Wind
T. Boone Pickens made a play for wind in Texas, then very visibly backed out of it. Wind would work well offshore of New England, but has been blocked by the Kennedys, among others, for ruining their views. In general, a spine of wind down the Great Plains would make sense, given the wind there. Windmills could become a cash crop.
Part of what deterred T. Boone as well, besides not being able to shake down governments for subsidies nor investors for funding, was the need to connect the windmills to the grid. In vast areas where wind would work, the grid is inadequate, non-existent, or caught in political wrangling. Hard to make wind a cash crop if the grid won't connect to it! Watch for approvals of new powerlines to renewable areas to inform as to where to focus investments, such as just happened in SoCal.
A microcosm of the wind market is the Bonneville Power Authority, which runs hydro on the mighty Columbia River and wind in the breezy Columbia Gorge. The actual output in practice is far less than expected. This calls into question the cost estimates of wind. The BPA has found that at peak wind, they would overwhelm the transmission lines, and have to cut off turbines; and further have had to dump water over the dam without getting power from it due to the way nature works (the water flows even as the wind blows).
If you want to play this, David Fessler has a wind recommendation:
Wind installations will continue during 2010, but well off the record pace of 2008. Nearly 300,000 megawatts of wind farms are waiting for grid enhancements and upgrades. Vestas (Nasdaq: VWDRY.PK) is the world’s largest wind turbine manufacturer, with over 39,000 turbines installed around the world.
Solar
The solar sector is 3x more expensive other mainline energy sources, making it a bad bet for base energy production. Potentially solar can run down a cost curve, but it is having a terrible time getting out of the starting gate. I have an indirect interest in BrightSource, a solar-thermal engineering firm. Solar-thermal uses mirrors in the desert to drive a heat pump to spin a turbine. The team behind BrightSource was the pioneering team in the '80s behind solar-thermal in that wave of energy consciousness, and near the end had 90% market share. Yet steadily the subsidies were pulled as oil continued to get cheaper and cheaper, and the lights were turned out on their firm. Their new company hit a serious bump in the road this summer, when their plans to build a huge planet in the Mojave Desert were stymied by the local eco crowd (NIMBY!) as well as some obscure political interest by Senator Diane Feinstein.
UPDATE 12/22: that obscure interest of DiFi got revealed big-time today. The WSJ reported that she is now pushing for a huge National Monument to cover much of the Mojave. (See map.) She must have thought the timing right, given the positive reception to the recent PBS series The National Parks: America's Best Idea, by Ken Burns. She would protect over a million acres. California has required utilities to invest in solar, and they would need 128,000 acres for that; but almost a million acres of projects have been proposed (which is down from a initial 2.5 million acres). Projects are being cancelled; the NYT says DiFi's move has further scuttled 13 big solar plants and wind farms planned for the region. The bill does try to speed up approval, but the local NIMBY crowd will still have to be dealt with. The WSJ notes that:
The Mojave is particularly attractive because it not only offers nearly
uninterrupted days of bright sunshine in a sparsely populated area, but
lies near a major electric-transmission corridor from California to
Nevada.
I suppose there is always Arizona next door, but this puts a huge damper on utility-scale Solar.
Possibly the solution lies in photovoltaic cells (PVs). The SciAm article A Solar Grand Plan (you can download it here) paints a compelling picture of mass PV farms across the Desert Southwest, joining that theoretical spine of wind down the Plains. It is difficult to see how it is more than science fiction, unfortunately. It requires some engineering breakthroughs, such as mass storage of energy in caves/mines using compressed air, and superconducting DC lines that stretch from the Desert Southwest to populated centers across the country. More
daunting is the need for 30,000 sq miles (20 million acres) to be covered with PV cells along with concrete, power lines, roads, and
the support for a massive construction project. To give that
perspective, that is the size of land between SF and LA, from the ocean
to the mountains. Hard to see how that swathe can be available
somewhere, and more than that can be built upon. That is a lot of Mojave Deserts, and we just lost that one. We might be able to
find some of that area available in Arizona, but the system needs water to construct and water
to maintain (PVs get dusty).
Still, it appears that distributed PV cells (small panels on homes and businesses) have a market, because the savings at the retail end of the utility price curve are enough at the margin to cover the 3x higher cost. Currently the Chinese are dumping PVs into the US, reusing excess semiconductor capacity. This is depressing domestic production but incenting domestic uses. A number of thin-film PVs are coming online in 2010. (Disclosure: I have an indirect interest in Miasole, one of the thin- film ventures). Perhaps the Chinese PVs will make a market for thin-film.
Caution is warranted in solar, as the initial exuberance has fallen to hard economic and logistical realities. Nonetheless I agree with David Fessler's comments on this sector:
This is one sector that should continue to see consolidation in 2010. With an excess of silicon wafer capacity and new low-cost thin-film designs just now coming into production, expect the transition from silicon-based panels to thin film to continue in 2010. And despite the negative press, one of the ultimate winners in this space will be First Solar (Nasdaq: FSLR).
Here is a bit more on First Solar, from Toby Shute, who posts on solar regularly in SeekingAlph:
The thin-film kingpin came back the next day with guidance for 2010, plus news of a major capacity expansion. The forecast was notable in that it went beyond the usual sales and margin figures, and it included free cash flow guidance. Free cash flow is a rare commodity in this capital-consuming industry. With such a robust financial profile, it's no surprise that First Solar is comfortable expanding its current capacity by nearly 50%
UPDATE 12/22: the story above about the loss of most of the Mojave for utility-scale solar puts a huge risk into First Solar. GreenBeat has this story:
It turns out First Solar has dropped four large-scale solar plant projects in California alone, according to a report from investment firm Wedbush Securities. In each of these cases, the company’s plans were denied by the Bureau of Land Management. At the same time, it was revealed that one of its 150-megawatt projects slated for 2,100 acres in Colorado has now also been cancelled.
The central message behind First Solar’s recent success was that
utility-scale solar plants would soon be a reality. [Now] it looks like First Solar is
having more trouble than it bargained for, boding even more poorly for
others striving toward the same goals. In short, utility-scale solar
could still be a ways away.
UPDATE 12/23: Solyndra, a thin-film maker competing with First Solar, is poised to go IPO. An analysis of their filing, however, shows they are way behind First Solar in their PV cell costs: they sell for $3.42/watt but make for $6.29/watt. Ouch. Apparently their PVs are easier to install, and that saves their buyers as much as $2-4/watt, dropping the effective cost to $2.79-4.79. But this doesn't appear competitive:
Compare this to First Solar (FSLR). First Solar's average manufacturing cost per watt
declined by $0.23 per watt, or 21.3%, from $1.08 in the three months
ended September 27, 2008 to $0.85 in the three months ended September
26, 2009.
Or compare it to a silicon solar vendor like Trony Solar (TRO).
Trony Solar's average manufacturing cost was $1.15 per watt for the
fiscal year ending June 30 this year, the company said in its SEC
filing. From June to September, the company lowered the cost to $1.09
per watt.
Solyndra must also compete head-on with the plunging price of
flat plate panels from BP Solar (BP), Suntech (STP), Mitsubishi, etc. while lowering their cost almost an order of magnitude from about $6 per Watt to under $1 per Watt.
Hence, First Solar still looks relatively attractive, but whether they are a buy on an absolute basis is unclear at best; first the collapse of utility-scale projects must be taken into account. Solyndra targets rooftops with a unique cylindrical design.
Natural Gas
Nat gas seems to be the transitional fuel from oil to renewables like geothermal. We have had recent large discoveries, and gas has become cheaper than oil. In the longer run, nat gas may become the foundation of the so-called hydrogen economy, where it can be used to fill up hydrogen fuel cells (the CH4 in gas is converted to H). This is several years away from commercial development.
There are many ways to play gas. Some ideas include ETFs like FCG or DIG. (Please note that I am not endorsing these, just passing them on.)
There is a lot of backroom political wrangling over nat gas. if you go into this area, be sure to keep an eye on influence peddlers in Washington. Or hire your own!
Nuclear
Quick comment on nukes: there are a bunch of future models being designed. The most interesting uses Thorium as a fuel. A long-term play is to look into Thorium.
UPDATE 12/23: Thorium makes a better fuel than uranium: much safer. more abundant, less waste, and no proliferation potential. India and China in particular are all over it. The US considered and rejected Thorium reactors in the '60s precisely because it had so little waste; they wanted to use the uranium waste for bombs.
UPDATE 12/22: Another play is to invest in compact nukes - small self-contained reactors that can power a large factory or a city. We have run nuclear powered subs and carriers for 50 years, safely; so why not use those design ideas commercially?
It turns out there are five fission and two fusion start-ups, including Hyperion, NuScale and Tri Alpha. Also, some of the large nuke builders like GE, Toshiba, Hitachi and Areva are looking at this. The reactors are small, some small enough to fit on a kitchen table. They are self-contained and can be thought of as nuclear batteries. They can be built in a factory, shipped to a site, and plunked in the ground. When they run low, they get pulled and replaced, and processed back at the factory.
Sounds pretty compelling. What's the catch? Bob Metcalfe, the inventor of Ethernet and a prominent venture capitalist, touted this idea in the WSJ, but said he wasn't investing himself. As he puts it:
As venture capitalists, we at Polaris might have invested in one or two of these fission-energy start-ups. Alas, we had to pass. The problem with their business plans weren't their designs, but the high costs and astronomical risks of designing nuclear reactors for certification in Washington.
The start-ups estimate that it will cost each of them roughly $100
million and five years to get their small reactor designs certified by
the Nuclear Regulatory Commission. About $50 million of each $100
million would go to the commission itself.
The problem with nukes is political, and reflects a common pattern when a new technology comes in: we first treat the new as different, and only later learn it really wasn't that different. Yet the damage is done and hard to unwind.
My favorite example of this is the Fairness Doctrine in broadcasting. Under the First Amendment, no one would think of restricting the number of newspapers or limiting their editorial control. Yet when radio and later TV came in, this is precisely what happened. The rationale was that spectrum was limited, and so would be the voices; but ask yourself, are there more newspapers in your town, or radio & TV outlets?
We lucked out in the US with the Internet, and I give Al Gore credit not for inventing it but for keeping the government's hooks away from it.
We got very unlucky in the US over nukes. First, the Atomic Energy Commission was heavy-handed and excessively subsidized the industry, so a reaction was predictable. Second, a silly Hollywood movie, The China Syndrome, came out almost simultaneously with an incident at Three Mile Island. Fear trumpeted logic. No nukes in the US since then. Nukes are not really that much more difficult to manage than other toxic chemical plants, yet are seen as much riskier, and are buried in regulations, approval and litigation.
The good news is even with the noose around their neck, nukes appear to be able to compete economically as base energy sources. SciAm has a good online site to learn more about nukes.
While pushing for nukes may be good energy policy, it seems a tricky area for investors, too subject to the whims and fancies of craven politicians and emotive pressure from relatively uneducated voters. Maybe Metcalfe's "nuclear batteries" will be approved and then worth investing in. I would wait for that.
If you feel compelled to find a play, those new nukes that are added to existing facilities, as extra reactors, are much more likely to be approved and operational in an investment time frame than new sitings.
Electric Vehicles
A lot of action here, although little yet public. The nano-scale Lithium battery maker A123 went public this Fall, and is worth watching. Tesla Motors should go out in 2010 (disclosure: I have an indirect interest in Tesla). It should get a good reception, given it is the first one out. Fisker with its Karma plug-in should follow.
This may be a market where it is better to catch the early IPOs than wait. A lot of electrics will be coming out in the period from 2010-2012, including the Chevy Volt. The current hybrids are expected to give way to plug-in electrics of various designs. The primary battle is between all electrics like the Tesla and electrics with range-extenders (motors or fuel cells) like the Volt or the Karma. Toyota has a huge lead with the Prius, and recently announced a plug-in lithium-ion car with a motor range extender. Consequently the competition should get pretty fierce.
An interesting longer-term play is to invest in Lithium. All the future batteries are using lithium-ion technology. It is also stressed by laptop/netbook and mobile-phone demand. The coming tablet computers will further increase demand for lithium.
UPDATE 12/26: Besides investing directly in lithium, one could invest in lithium battery companies such as A123. A contrarian perspective on lithium calculates that the lithium future has been fully baked into the valuation of A123 and competitors, and that traditional lead-acid batteries are undervalued. Perhaps, but never under-estimate the value of a good old fashioned bubble, in this case an electric car bubble, which has not yet warmed up. Again, my suggestion is play the early IPOs in this space, if you can.
As a personal note, four of the five cars in my family (including kids who have flown the coop) are hybrids. I think they drive better - a smoother and quieter ride. While the GW alarmism will abate, and carbon-trading flop, the transition to electric vehicles will continue.
Efficiency
Another whole category is energy management, ranging from the Smart Grid for utilities, to energy metering for businesses and homes, and down to systems to lower energy usage in devices. Again, few companies yet public, but a plethora being invested in via venture capital and the Dept of Energy. This is a space to watch.
UPDATE 12/24: Other pundits are weighing in on the implications of Copenhagen for investors. Greentech Media agrees that the focus should shift away from grandiose climate legislation towards subsidies for 'green jobs' and especially to energy efficiency. The investment plays here may stretch outside of VC into PE and public companies:
Many VCs will look for IT-based ways to try to play the wave: Home
energy monitoring, LED-based lighting, etc. are already popular sectors
and will become more so. But I think VCs will be left out of most of
the emerging wave of energy efficiency adoption, because it will be
mostly service-based, and tapping into the biggest pools of incentives
will require working with utilities and governments. Non-VC investors
may be the most critical source of capital for energy efficiency. And I
also expect a fair amount of mid-market private equity activity in the
sector as well.
A word of caution on investing in areas with "green jobs". Much of the green jobs push will be for core manufacturing, often combined with temporary construction jobs (building solar plants, putting solar cells on buildings, etc.) Examples that would drive green jobs are PV cells and batteries for electric cares. Yet, we already have a glut in PV cells and a possible glut in
Lithium-Ion batteries that may disappoint investments in core manufacturing. The rush to produce capacity, which until last year was
funded with cheap capital, has gotten way ahead of demand for the
end-use products built on top, such as electric cars or utility-scale
solar.
One final note of caution that applies even to energy efficiency deals: avoid investing in areas with heavy government subsidy,
whether from the Stimulus bill or from Dept of Energy programs. In
particular, Smart Grid ventures may be over-invested in. In areas without heavy government subsidy, energy efficiency deals will be more attractive since the ROI from saving cost is the gift that keeps on giving.
