Hydrogen.

In green technology circles, just mentioning the word is enough to start an argument.

Hydrogen could become a ubiquitous source of electricity and heat, say advocates. Plus, it’s somewhat prevalent. Hydrogen remains the most abundant element in the universe and every molecule of water contains two atoms of hydrogen.

Some car makers — Toyota, Honda, Mercedes — argue that hydrogen fuel cells will ultimately wind up in vehicles, and thereby reduce both the weight and cost of these cars. Hydrogen cars would also eliminate the pain of charging. It takes three to eight hours to charge car batteries; filling a car’s tank with hydrogen takes five minutes.

Now let’s cue to ugly reality. While hydrogen fuel cells don’t generate carbon emissions directly, producing hydrogen today is a dirty business. Most chemical companies make it by breaking up methane molecules: every kilogram of hydrogen produced through this process results in 9.3 kilograms of carbon dioxide, which typically gets released into the atmosphere.

Pulling hydrogen from water molecules requires, in most circumstances, tremendous amounts of energy. Some have suggested that the only way to make it economical is to harness the waste heat from nuclear power plants. But that would require more power plants.

Fuel cells — which depend on expensive materials like platinum — remain in the experimental stage, as well. I’ve driven a few hydrogen-powered cars. They are the best-driving, smoothest-handling cars I’ve ever experienced. I asked a company representative how much they cost. “Probably a million,” she estimated. The Hydrogen Highway lead to one place: a dead end.

But back to the advocates. Hope springs eternal. At MIT, Daniel Nocera has identified a chemical catalyst that can reduce the amount of energy required to strip hydrogen from water molecules. Others, like SignaChem, have come up with dry chemical pellets: put them in water and hydrogen is created.

Hydrogen advocates — and there are fewer of them now than there were even three years ago — readily admit the technology has not lived up to its promise. Virtually all of the experience to date seems to bolster the case of the critics.

But still, the tantalizing possibility beckons.

Maybe…or maybe not.

What do you think?

Supporters of energy efficiency often talk about the tremendous untapped opportunity to squeeze energy savings out of the existing building stock. This fact has been proven time and time again.

However, choosing the right measures that will achieve the deepest levels of efficiency in the most cost-effective way remains extremely difficult. In a recent survey that Pike Research conducted on behalf of Rocky Mountain Institute, 19 percent of building retrofit industry professionals indicated that auditing / benchmarking and selecting energy efficiency measures are the most challenging phases in the retrofit process to execute. Not to mention the fact that many in the retrofit industry cite a severe shortage of qualified energy auditors, particularly when it comes to the holy grail of retrofits, the investment-grade audit. And, with a growing number of new laws that will require them to provide energy bills to prospective tenants and buyers in major U.S. cities, large property owners are starting to consider ways to expedite the retrofit process in any way they can.

A new offering from start-up company Retroficiency is aiming to make retrofits easier for energy service companies and large commercial building portfolio owners and managers. The company’s energy efficiency identification and qualification (EIQ) platform systematically analyzes the potential benefits of thousands of commercial building energy efficiency measures.

The company developed its SaaS platform by leveraging information from tens of thousands of energy audits and demonstrated savings from energy efficiency measures. Using it, a commercial building owner can input the location, size, and a number of other basic building-related inputs to determine a suite of energy efficiency measures that will cut energy consumption in the building.

I recently had the chance to speak with Bennett Fisher, the CEO of Retroficiency, about the solution and how he thinks it will transform the industry. “We’re flipping the retrofit process on its head,” Fisher says. “Instead of saying, ‘Here’s what you should do to make your building more efficient,’ we can now ask, ‘How much energy do you want to save? We’ll help you get there.’” In other words, an energy or facility management company can say that it wants to cut energy consumption by 20 percent in all its facilities. The Retroficiency platform works backwards to select the best suite of efficiency measures to achieve those savings.

The idea definitely hits a nerve in the retrofit industry and others in the energy efficiency industry agree. Earlier this month, Retroficiency announced that it had raised $800,000 in angel funding. The round, led by World Energy Solutions, which has leveraged the Retroficiency platform to roll out a new product, the Virtual Energy Audit, will help Retroficiency further develop and commercialize its offering. “The world is changing from where it was ten years ago,” points out World Energy Solutions President and COO, Phil Adams. “It’s no longer just a question of paying your bills but of how you can maximize energy savings.”

Needless to say, Retroficiency’s offering represents an innovative new entrant in the energy efficiency space that will help tap the efficiency potential of the built environment.

Editor’s Note: ICResource.com has a deep history as an advocate for renewable energy and sustainable development including one of our founders raising angel funds for Stirling Energy System over a decade ago – now fully capitalized and building the two largest solar thermal power plants in the world in southern California in 2010.

Press Release: December 23rd, 2009

SES started bringing dishes on sun shortly after 11am via laptops at each Dish Group. Once each unit was on closed-loop tracking control of it was transferred over to the SCADA system. At 12.30 we put the 60th dish on sun and were generating 1,058kW. We ran the field for a full hour and hit a peak output of 1.12MW. we then successfully took the field back off sun one dish group at a time using the SCADA system to put dishes back into windstow. This was achieved with dirty mirrors, DNI of approximately 850 Wm2 and maximum shading due to sun position so the outlook of hitting our performance targets under standardized operating conditions looks very positive. Its also worth mentioning that the controls software, SCADA and Hydrogen systems all performed as expected on the day.

This is a very significant milestone and I want to thank everyone involved across all the teams and from both Tessera Solar and SES for the enormous push over the last few months to get this over the line before the end of the year.

Well done everyone – now we can really relax and enjoy the break!!

Part I, Picking the Winners

We are living in the Age of Uncertainty. Nobody knows how bad the economy really is or how long the pain will persist; nobody knows what type of stimulus package we need or whether a stimulus will actually work. And nobody knows where clean technology innovation is headed, given the current tumult in the capital markets.

Despite financing the future for hundreds of emerging growth companies over the past 25 years, I admit to not having all the answers today, at a time when that would be immensely helpful.

But I do know that the current stimulus package – with approximately $90 billion worth of energy-related spending and tax breaks – has the potential to boost certain sustainable industries and renewable energy sectors that have enormous job-producing potential, and that these good-paying and high-value positions will enhance economic growth both today and tomorrow.

An Extended Keynesian Injection

Unlike the New Deal stimulus, this 21st century eco-stimulus offers us an extended Keynesian injection because new green companies and new clean industries will be created from the ground up while existing – but still maturing – segments of the New Energy Economy will expand and extend their reach.

The businesses and sectors that stand to gain the most from Washington’s legislative initiative will be the ones that can best harness public and private sector capital flows to generate a fairly quick payback. Every enterprise in the clean tech world is looking for stimulus money, but if you can’t break even on a cash flow basis anytime soon, there’s little sense in approaching lawmakers on Capitol Hill for financial aid.

Energy Expenditures

Congress is still not officially signed off on the size and composition of the stimulus. So, my informal, conservative and real-time dollar break out, which is subject to change as legislators crunch the numbers, currently looks like this:

  • Energy Efficiency and Transmission – $50 billion
  • Renewable Energy Tax Credit Extensions – $13 billion
  • Tax Breaks for Large-Scale Renewable Projects – $11 billion
  • Energy Efficiency Improvement – $9 billion
  • Renewable Energy Manufacturing – $1.4 billion
  • Department of Defense Energy Upgrades – $4 billion

Yet even as the legislation is hammered out before going to President Obama for signing, it’s possible to identify three potential winners that will have a tremendous economic – and job-creation – impact on the post-petroleum era.

First, the solar and wind power industries. These sectors are struggling today because debt funding and critical tax equity take-out financing has dried up; but I believe they could experience a reversal of fortune if Congress includes a refundable tax credit in the stimulus package (See Part II, following this story).

Taxing Matters

Amending the tax code in this way makes sense because the refundable tax credit would be a financeable arrangement and go directly to the solar and wind developers, who created a combined 30,000 new jobs in 2007 and 2008.  With the right tax policies in place, the solar energy sector alone could create 440,000 permanent jobs and spur $325 billion in private investment by 2016, according to Navigant Consulting.

The second potential eco-stimulus winner will be the green building industry, which represents a mammoth opportunity and offers a powerful

long tail in terms of new employment possibilities.

Building for the Future

The numbers tell the story in a stark way here: There are currently 120 million homes, 5.1 million commercial buildings and legions of government office structures in the U.S. today. These structures account for approximately 40 percent of the nation’s carbon emissions and consume 60 percent of its raw materials, so if even a reasonable percentage of them were retrofitted and became more energy efficient and environmentally friendly, we’d be setting a major economic multiplier in motion.

The material science sector could especially benefit from a green building stimulus surge if it develops and markets products like clean cement and other building products; and the software industry could also prosper by creating automation services and systems to manage the homes, offices and buildings that are working toward greater energy efficiency.

A Jolt of Prosperity

The third stimulus beneficiary will be the nation’s outdated and outmoded electricity infrastructure, which needs to be upgraded with intelligent and breakthrough digital technology that will boost efficiency and reliability while lowering cost.

A number of skeptics talk about how daunting this overhaul would be. And they are right. The current electricity grid feels like a 19th century creation rather than a 21st century innovation. And it’s a jumble of fraying old wires, decaying transmission stations and antiquated analog equipment that is holding the nation’s global competitiveness back.

But this effort would be well worth it. A recent analysis by the Grid Wise Alliance reveals that $16 billion in smart-grid disbursements over the next four years would serve as the catalyst for projects worth $64 billion. These projects would create nearly 300,000 direct and high-value jobs between 2009 and 2012; and 150,000 of these positions would be established before the end of 2009. In addition, the Grid Wise report indicates that 140,000 indirect jobs would be generated between 2013 and 2018 as a result of smart-grid investment.

A Rising in the Valley

Smart grid innovation and infrastructure improvements would – in the same way as green building retrofits – help the software industry play a much-needed role in clean technology. And, with information technology hitting a plateau, Silicon Valley could reinvigorate itself by embracing a modernized electricity grid through two-way communications devices, smart meters and advanced control systems that take all the gathered energy information and manage it in real-time.

Franklin D. Roosevelt’s New Deal spending programs struggled to reverse The Great Depression for almost a decade, and it wasn’t until the United States geared up for the Second World War that the economy finally righted itself.

A New New Deal

I believe Barack Obama is more fortunate than Roosevelt because the nation is on the brink of a New Energy Economy today. If Congress and the new President choose eco-stimulus programs and policies wisely, we may see prosperous and peaceful new horizons sooner rather than later.
