The Energy and Climate Challenges

“Our ability to find and extract fossil fuels continues

to improve, and economically recoverable reservoirs

around the world are likely to keep pace with the

rising demand for decades.”

Steven Chu and Arun Majumdar, Nature (2012)

Will we run out of oil and natural gas?

U.S. Oil Production (1945 – 2012)

2013: 7.5 M bbls/day

U.S. oil production from tight oil is ~ 4.5 M bbls/day

The increase in oil production, ~ 4.5 M bbls/day, is more than the oil production of all countries except Saudi Arabia, U.S. and Russia

2014: 8.5 M bbls/day

~ 70% of the total world oil reserves is heavy, extra-heavy, oil sands and bitumen

≤ 22.3°API

≤ 10°API

Brent, WTI 38° - 40°API

Steam-assisted gravity drainage (SAGD) Estimated recovery 50% - 60%

Can a mixture of steam and CO2 allow lower temperatures to decrease energy use and increase oil production?

The estimated reserves of all deposits in western Canada and eastern Venezuela is ~ 5.3 trillion barrels.

2.  The Clean Air Act will be used by EPA to control these pollutants.  

•  Utility companies realize they will have to control carbon emissions. They need a stable policy so they can make future investment choices.

•  Most major multinational oil companies carry an internal price on carbon to guide future investment decisions.

Energy Quiz (True or False)

A reliable electrical grid cannot tolerate more than 5 - 10% intermittent renewable energy.

In 2013, Hawaiian Electric Co. (HECO) claimed the grid could not sustain more that 3% - 4% solar power. The intermittent power

would threaten reliability and safety.

FALSE

51

Careful  planning  is  needed  to  op6mize  the  lowest-­‐cost  solu6on  

52  

Lowest cost solutions when renewable energy becomes > 30% of total energy will require  

(1)  Long distance Transmission,

(2)  Load-management, (3) Automatic control of two-way energy flows, (4)  Energy storage

(5)  Stand-by generating capacity.

It  is  far  easier  to  meet  energy  demands  using  coal,  natural  gas  and  hydropower  than  to  manage  renewable  energy.    U6lity  operators  will  take  the  easy  (and  safe)  op6on,  rather  than  find  a  lower  cost  op6on  that  requires  more  thinking.    

Regulators have to know about existence proofs of (deployed) state-of-the-art technology.

53  

Why aren’t utility companies focused on transitioning to the low-cost option?

Use of “energy-on-demand” energy sources does not require technical innovation. Most utility companies move at glacial speed in the adoption of new technologies.  

This comparison maybe unfair to glaciers. With climate change, some glaciers are moving faster than utility companies.

This technology could be as disruptive to electricity generation and distribution as the internet was to

publishing and entertainment

The cost of home solar energy will likely achieve the DOE goal of $2/watt and utility scale cost of $1/watt.

(L.C.O.E. ~ 6.5¢/kWh)

Battery storage of a ~ 6 kWh system may be ~$1,200 in a decade, and the total installed 6 kW/6kWh

system cost could be < $15,000.

A proposed solution to align utilities company incentives with deployment of solar energy:

Offer customers roof-top electricity & in-home energy storage owned, installed and maintained by the utility company.

•  Home owners get low electricity rates and ~ 10 kWh of local storage (> 1 week of blackout resistance).

•  Distribution companies get indoor energy storage at the ends of their distribution network.

65  

Summer - Winter energy storage •  Transmission of solar energy from North Africa

and the Middle East may be possible, but energy security is an issue.

•  Chemical energy storage: e.g. use excess night time electricity to split water into H2 and O2 and combine with CO2 to form liquid hydrocarbons that can be shipped anywhere in the world
