Summary:

At the end of the day, it may be the really boring stuff — uh, industrial energy efficiency — that does the most good and needs the most support.

President Obama signed an executive order on Thursday that seeks to boost the energy efficiency of the industrial sector by implementing a technology called combined heat and power or (CHP). Great, so WTH is CHP?

Combined heat and power or cogeneration is the simultaneous creation of both electricity and heat from a single fuel source like natural gas, biomass, coal, or oil. The concept has been around for over a century and cogeneration systems are inherently more efficient than the act of separately generating electricity from power plants and heat from heating equipment.

Combined heat and power can be delivered on both a small scale — like a residential house using a fuel cell for electricity and heat. Or on a much larger scale, like an industrial district heating project, which generates both electricity and steam or hot water in a central facility and pipes that hot water to a network of nearby buildings where it is used for space and water heating.

Because CHP is more energy efficient, it reduces potential greenhouse gas emissions, and also cuts energy costs for companies. A couple years ago a study came out from Oak Ridge National Labs that found that boosting the use of combined heat and power to 20 percent of the generating capacity of the U.S. by 2030 would save 5.3 quadrillion thermal units of fuel per year, which is equal to almost half the total energy consumed by U.S. households. That much CHP could also lead to a 60 percent reduction of carbon emissions, which is the equivalent of taking 154 million cars off the road.

Obama wants to encourage the creation of combined heat and power for the industrial sector — picture facilities like paper making factories, and aluminum smelters — and is calling for the creation of 40 GW of new combined heat and power facilities by 2020. That, quite simply, is pretty huge.

Obama wants to encourage the creation of these systems by offering support to states who want to build CHP, and offering incentives to companies that install CHP. Obama also calls for the Department of Energy, Commerce, Agriculture and the Environmental Protection Agency to convene workshops and research on the subject, and also is looking at ways to encourage the private sector to invest in these projects.

At the end of the day, it may be the really boring stuff — uh, industrial energy efficiency — that does the most good and needs the most support.

  1. Not to steer the discussion towards politics, but its remarkable that he is still pushing for these steps in a political year when ‘green energy’ has become a joke by folks patronized by these powerful oil lobby.

  2. Of course prvention an reduction of energy comes first!! But I cannot imagine a better ambassador for this sympathetic and relatively simple and underestimated “plug and play” solution for saving money and reducing carbon emissions.Companies throwing away their money on > 150.000 m3 gas can make ROI of < 3 or 4 years, while reducing carbon wit even up to 50% for their energy. I gladly support any company to calculate the benifits in their special case. Huub Schoenaker

  3. Great piece, but please, let’s all stop quantifying ghg reductions by saying how many cars they take off roads. How does that add to the understanding of the implications?

    To most people “taking x cars off the road” simply means “so I can get to work faster”, not, that we all get to keep our current climate.

    A better quantifying metric for grownups would be “How close would we get to the U.S. Copenhagen agreement of 17% below 2005 by 2020, by putting 40 GW of CHP online by 2020?

  4. You say Obama likes or wants three times in this short piece. Who gives a s**t what Obama wants? He does not have a clue.

    How about we let the free market decide what it wants.

    Personally, I would love to have a solar panel or windmill that gives me unlimited power, but the reality is the technology does not work yet costwise and as Obama proved pouring a half billion dollars down the Solyndra rat hole, we need to let the free market decide when the technology discussed in the article is ready. Not be subsidized or pushed down someone’s throat by a dictator.

  5. Doug, you’re a moron. Combined heat and power has been around for more than a century. This doesn’t need to be proven, it needs to be unleashed. There are 80 GW of combined heat and power (CHP) in the United States and hundreds more around the world. The issue in the US is the policies of the MONOPOLISTIC ELECTRIC UTILITY INDUSTRY that PREVENTS this technology from being deployed. Because if this were truly determined by market forces, we would have 3-4X the CHP we currently have. Do some research before you open your pie hole!
