Biological Substitutes for Petroleum Scaling Up Economically

As the price of petroleum edges up in fits and starts, booms and busts, substitution products are coming on board to replace petroleum in many uses -- including fuels, plastics, high value chemicals, lubricants, and more.
Making plastic from sugar can be just as cheap as making it from petroleum, says Dow Chemical. The company plans to build a plant in Brazil that it says will be the world's largest facility for making polymers from plants. _TechnologyReview
Rather than jumping on board the peak oil bandwagon of doom, many dozens of startups and large industrial players are lining up to produce substitution products and feedstocks.  The process of substitution takes time, of course.  But given the abundant energy resources of the planet, and the political will to develop them, there will be more than enough time to make the different transitions which will be needed.
Bio-based chemicals production has grown quickly in recent years, but it still represents just 7.7 percent of the overall chemicals market. Production has been limited in many cases to specialty chemicals or niche products. But Dow now says chemicals made from plant feedstocks may be ready to compete head-to-head with petrochemicals made in large volumes.

Most large-volume chemicals are made from petroleum. About 80 million tons of polyethylene are made annually around the world. But high oil prices have increased the costs of petrochemicals. And in Brazil, long-standing government support for sugarcane ethanol production has allowed the industry to drive down costs, making ethanol competitive with fossil fuels. Making polyethylene from sugar "would not necessarily be attractive in other regions," says Luis Cirihal, Dow's director of renewable alternatives and business development for Latin America.

The technology for converting ethanol into ethylene, the precursor for polyethylene, is not new. "The dehydration process for converting ethanol to ethylene has been known since the 1920s. The only thing that's really new here is the scale," Cirihal says. _TechnologyReview

Oil prices have been bouncing around from very high to very low for over 150 years.  Boom and bust has been the name of the oil game since it began.  Predictions of global oil depletion and consequent economic doom have been made over that same 150 year time period, and all have failed.  But that does not stop a lot of people from selling books, newsletters, seminars, and workshops in order to cash in on the cyclical sentiments of impending depletion doom which seem to come on with every boom cycle.

Trivial truisms lie at the heart of most mass delusions. The delusion of impending peak oil doom (POD) is no exception. The truisms at the heart of POD include: "the total supply of oil in the Earth is finite," and "oil wells deplete rapidly, once tapped." But the truisms can only take you so far, without questionable assumptions and educated guesses. A lot of people want to believe in doom, and are willing to take those leaps of faith into the unknown.

But there is no need to do that, if all you want to do is live a full, abundant, and satisfying life, despite the finite nature of world oil supplies. To do that, you merely need to keep a few general concepts in mind, and follow a small number of central parameters. More on that later.

Contrary to Peak Oil Orthodoxy, Oil Industry Reacts to Prices

Khaled Al Buraik, executive director of the government-controlled Saudi Aramco, announced that new technology could add as much as 2 trillion barrels of oil to global proved reserves.
Although the current global oil reserves in place are estimated at 14 trillion barrels, only about 1.2 trillion can be recovered, said Khaled Al Buraik, executive director of the government-controlled Saudi Aramco.

Speaking at a seminar in Riyadh, Buraik said the quantity of oil extracted so far worldwide does not exceed one trillion barrels.

"Advanced technology in hydrocarbon production could add around two trillion barrels to the existing proven crude reserves in the near future," he said in his address, published by Saudi newspapers on Monday.

"The real challenge for scientists and engineers is how to access to nearly 11.8 trillion barrels to meet the growing world needs of hydrocarbon in the future...what is needed now is more effort by scientists and specialists in this field to invent new methods and very advanced technology." _Zawya

Higher oil prices are spurring oil companies to increase their spending for exploration and production.

Brazil announces ambitious new underwater technologies to provide easier access to its vast undersea oil wealth

Liquified Natural Gas (LNG) is a growing component of national energy budgets from Britain to Japan, as a compensatory move against higher oil prices.

A new and ambitious approach to increasing the value of cheap, abundant natural gas, is being advanced by San Francisco startup Siluria Technologies.
Siluria has decided not to go after gasoline or diesel but instead to produce ethylene, a building block for plastics, fertilizers, pesticides, beverage bottles, tires and lots of other materials that are now made from oil. Ethylene can also be turned into alkanes, a class of hydrocarbons that are a component of gasoline.

A more important difference, though, could be the energy needed for conversion from the natural hydrocarbon molecule, methane, to the synthetic one, ethylene. In Siluria’s process, using a new kind of catalyst, that conversion gives off heat instead of requiring it. _NYT
I will present more information on Siluria in the future.

As you can see, advancing technologies will bring about both new proved oil reserves and production, AND new substitutes for crude oil in both fuels and chemical uses. Gas to liquids and LNG are certain to achieve traction for significant scaleup within the next 2 years.

It will take about 20 years for advanced biofuels and small modular fission reactors to get approved, licensed, and scaled up to provide significant quantities of energy and fuels. In the meantime, unconventional hydrocarbons such as shale gas, oil sands, coal to liquids, and heavy oils will scale up to ease the transition. If needed, oil shales and methane clathrates can provide more hydrocarbon energy than all other resources put together.
