A coming convergence in the energy sector?
I got my start in mainstream journalism as a technology and telecommunications reporter for the Globe and Mail, a beat I later took on at the Toronto Star and covered for six years before switching to energy. When I first started we were still using the term “information highway” to describe the coming convergence between the telephone and cable companies. Cable companies in Canada had their own networks, their own turfs, and their own regulated monopolies, while the phone companies had the same. The turfs overlapped, but the products and services stayed largely separate. You got cable from the cable guys, and phone service from the phone guys. The information highway threatened to change that, allowing the phone and cable guys to invade each other’s turf and bust through their respective monopolies.
The commercial Internet was still in its infancy and was considered part of the information highway. It was only in the mid-1990s that the Internet emerged as the dominant disruptive force in this technological vision. Internet Protocol, the communications standard underpinning the Internet, allowed all sorts of information — text, audio, video — to be treated as packets of data that could be shipped at high speed across cable and phone networks, which were privately operated networks that had on-ramps and off-ramps to the public Internet. As networks became faster, as compression of data got better, as computing power and memory grew exponentially, it became technologically possible and economical to deliver phone, broadcast, e-commerce, Web surfing and e-mail over both the cable and phone networks. The result: network convergence. Suddenly technology was creating competition in these regulated monopolies, forcing regulators to adapt and establish rules that permitted regulatory forbearance when competition in a market was deemed acceptable. For the phone and cable companies, the gloves were off. It was game on.
Why am I telling you this? Because I’m seeing the same thing happening in the energy sector. Electric utilities and natural gas utilities — in Canada at least — have operated in largely different worlds, each with their own rules and regulations, each with their own regulated monopolies and turfs. Actually, that isn’t entirely the truth. The electric utilities still offer electric hot-water tanks and electric heating, though this is slowly being phased out. But on the natural gas side, offering electricity directly to residential customers just hasn’t happened. Sure, in some jurisdictions there are parent companies that own both a natural gas utility and electric utility and offer services to customers on the same bill. But that’s not the convergence I’m talking about. I’m talking about using a natural gas pipeline network as direct competition against an electric transmission and distribution network.
I got thinking about this more after Bloom Energy announced its Bloom Energy Server. As far as technology goes, I didn’t see this unveiling as a big deal. Solid-oxide fuel cells have been around for decades. Today, there are several companies working on the same thing. What Bloom comes to the party with is good marketing, high-profile financial backing, and a great vision. By calling it an “energy server” it’s drawing parallels to the Internet, which gave us ubiquitous distributed computing, storage and delivery of information. Bloom is aiming to encourage distributed generation — the idea that power is efficiently produced and delivered close to the point of consumption, rather than generated far away from a central plant and transmitted long distances to the consumer. The latter sounds like mainframe computing from the 1970s and 1980s. We know what happened there. And yes, we do have distributed generation today in the form of rooftop solar, on-farm anaerobic digestors, industrial CHP and community wind farms, but for residential purposes there is nothing economical that can supply all our electricity and heating needs 24-hours a day.
An affordable Bloom Energy Server in every home, or something equivalent, would dramatically change the market landscape. It would allow natural gas to provide electricity, heating and hot-water heating with a single energy source, squeezing out the electric utility altogether. And even if it’s not in the home, large Bloom Energy Servers could be situated in the middle of subdivisions. Connected to a larger natural gas pipe, or better, to a local source of carbon-neutral biogas, one can envision district heat and power systems that are complemented by solar or geothermal. Sure, under this scenario, some wires would need to go into the home, but the community would be effectively off-grid. Again, electric utility gets the squeeze.
This changes the game, and presents challenges to energy regulators that have treated the natural gas and electric folks as distinct industries and markets. Suddenly these overlapping turfs mean something. Competition is possible. Regulation is out of date. This is a trend that will increasingly take hold over the coming decade.
K.R. Sridhar, founder and CEO of Bloom Energy, described his vision this way in the company’s first press release: “We believe that we can have the same kind of impact on energy that the mobile phone had on communications. Just as cell phones circumvented landlines to proliferate telephony, Bloom Energy will enable the adoption of distributed power as a smarter, localized energy source.”
I don’t agree with Sridhar. The cell phone analogy doesn’t work, because he conveniently ignores that you still need a natural gas pipeline. Mind you, if a small village in India wants to turn manure and other waste into biogas and use that to power itself, that would work and the Bloom Energy Server would enable it. Also, the fact that the Bloom box works in reverse means you can hook up a wind mill or solar panel and have it generate storable hydrogen, which can be converted back into electricity by reversing the process again. It’s possible, one day, but a lot of things are possible — let’s stick with what’s practical, economical and likely.
Another reason the cell phone anology doesn’t work is because the compelling part of cell phones is that you can carry them wherever you go. Unless Sridhar has plans for a pocket-sized Bloom Energy Server that operates on the sweat from your body, this won’t have the same impact as wireless portable communications.
I think a more accurate comparison is the impact of the Internet and Internet protocol. Before IP the phone networks and the cable networks operated in their own worlds. With IP they now invade each other’s worlds. We’re seeing something similar unfolding in the energy market. We’re seeing energy convergence.

Wow, that’s really something. They key factor to small-scale generation has been efficiency and emissions for a long time. If this thing can generate electricity from natural gas just as, or more, efficiently as a large-scale plant could, then a lot of problems could be solved by implementing local generation facilities. Not to mention that this would be one of the first steps into the hydrogen economy.

I agree that fuel cells are the future in North America. With the shale revolution, natural gas will be cheap and very very plentiful going forward. The issue with fuel cells just comes down to cost curve, reliability and a decent operating model.
Hurdles:
Cost Curve: The cost to get fuel cells down to the $1500-$2000/kw range (which is still a premium to the build out of a baseload coal plant) one company would have to pump out 100,000 kw worth of units first. Won’t get there without govt help.
Reliability: Degradation of fuel cell efficiency is about 2% a year… not fantastic right now. Also, SOFC planar cells (as opposed to tubular) have issues with cracking after surprisingly few cycles. Tubular SOFC holds better promise in this regards.
Operating model: There are huge logistical hurdles with this thing, you basically have to swap the fuel stack out after 5 years or so. Lots of maintenance.
In terms of the Bloom hydrogen thing, the hydrogen output of the unit is very low… I ran some quick back of the envelope stuff and it would basically get your hydrogen car about 5 miles based off a nights production (if that)? Very inefficient right now, so you are right to discount this.
Anyways, Bloom gets all the hype, but companies like Acumentrics, CFCL, Ceres etc… are fairly advanced as well.

Both, Tyler and Ivan are right. For every engineer out there the Bloom Energy box is old news. At best is a good marketing stunt in order to push their fuel cell technology into mainstream, “off the shelves’ kinda approach. Which is not a bad thing after all. Most likely is going to be a flop. I don’t believe the subdivision approach will fly for any North American city. It’s about people mentality associated with costs. Will see.

The thing that puzzled me about the bloom launch was that heat didn’t appear to figure in the equation (at least the equation that they communicated) at all. Not even to generate cooling for the servers it was feeding electricity to. Did they ever confirm that the heat would be utilised? It’s quite frankly a pointless waste of energy if it’s not.
