Australia to have 100% Renewable Energy by 2020


Australia is on a path to rely on 100% on renewable energy sources by 2020. It was based on the research by Melbourne University’s Energy Research Institute through its Evironmental group Beyond Zero Emissions which was presented to the Australian Parliament.

The Zero Carbon Australia Stationary Energy report claims at a price of A$37bn ($32.4bn) a year Australia can totally replace fossil fuel baseload electricity using renewable energy technology that is already available today.

Technically, the strategy aims at a mix of 60% of energy from solar thermal with molten salt storage and 40% from wind power with possibility of advanced solar photovoltaic (PV) to hit grid parity between 2015-20.

Malaysian Researchers Looking at New Biofuel Technology

Malaysia University of Science and Technology (MUST) is developing new ways of using oil palm-related products to produce renewable fuels, in what is seen as a response to European Union concerns in food and environment-related carbon balance. 

The MUST university is collaborating with a German research organization, Fraunhofer to work on directly processing oil palm biomass into biodiesel, instead of bidiesel being produced from crude palm oil. However, the MUST-Fraunhofer research is focusing on making the fuel from non-CPO biomass. This is to alleviate the mass requirement for oil palm plantations where only 10% of the biomass comprises CPO (Crude Palm Oil) and the rest includes fibers, empty fruit bunches, shells, fronds and tree trunks. 

Much of the reasearch will be to turn non-CPO biomass into gas and liquefied gas for usage as gasoline and biodiesel which will see bigger commerical gassification plant in Malaysia from palm oil. MUST is in the hope that the technology to be developed for commercial use in 2-3 years.

Japan Energy Venturing Into Petrochemicals from Plastics

Japan Energy has become the Japanese first refiner to use processed waste plastic as a thermal cracking fuel at its Mizushima refinery. The technological breakthrough is seen as a great potential for the company as petrochemical feedstock is skyrocketing and plastic wastes will not only save feedstock cost but it might as well be counted as negative cost due to save on waste management.

The nation’s sixth largest refiner has the capacity to turn 1,000 kilolitres/year of liquefied waste plastic to petrochemical products using the hydrogenation refining unit at Mizushima. Most of the refined products will be naphtha. Currently there is an abundance of plastic wastes in which Japan generates 10 million tonnes of waste plastic in 2006. Only 5,000 kilolitres of liquefied plastic was produced for refiners from the total of 10,000 tonnes processed.

European Companies Urged to Grow in Specialty Chemicals

Central and Eastern Europe (CEE) chemical companies were urged to grow in specialty chemicals. European specialty market’s production value expected to rise 7% a year until 2012, compared to only 4% for the commodity market.

Long gone the commodities game of sustainable long-term success with a focus on operational excellence, the money now is in specialty markets as value-added chemicals.

CEE companies should venture into huge strong domestic demands for specialty chemicals such as titanium oxide (TiO2), soda ash, methylene diphenyl diisocyanate (MDI), toluene di-isocyanate (TDI), specialty plastics and adhesive.

In general, CEE companies have great advantage in terms of highly qualified and motivated workforce with solid experience and tradition in running petrochemical plants. The biggest obstacle currently is probably sourcing of oil and gas, which most CEE companies are dependant on Russia.

Cellulosic Ethanol for Biorefineries Hitting US

US is investing $114m for cellulosic ethanol projects to explore cellulosic ethanol feedstock options and production processes for biorefineries. The investment is for four years development of funding of four pilot plants before contribution from private sector. The government funding is seen as part of US goal of making cellulosic ethanol cost-competitive with gasoline by 2012 under the President Bush administration.

The pilot plant will be able to produce about 2.5m gal/year of cellulosic ethanol in a plant to build a commercial ethanol plant with annual output capacity of around 25m gallons or 75,000 tonnes.

There are as yet no commercial-scale cellulosic ethanol production units in the US. Current technologies explored under study for cellulosic ethanol production includes conventional cellulosic conversion technologies, biogenetic and microbiotic conversion of cellulosic feedstock into cost-effective fuels.

Cellulosic Ethanol Production Route from Biomass

Incentives to go with ethanol is pressured under the Energy Independence and Security Act of 2007 which requires the US to produce at 100m gal/year of cellulosic ethanol by 2010 and 500m gal/year by 2012 in the route to achieve 36bn gal/year of renewable fuels in 2022.

Biodegradable Plastics Need Organics Disposal Program

Biodegradable bags which have been in discussion for many years, seem to have grown at slower pace with development expected to happen due to the growth of organic recycling in the US as predicted by BASF.

Biodegradable bags are now extensively used as organic waste collection bags, can liners and lawn and leaf bags in the US, Canada and Europe. The long waited biodegradable into grocery bags is yet to happen. Grocery bags are one of the major used of plastics in the bags segment. Currently polyethylene bags (PE Bags) are used.

The conversion of biodegradable bags, is only feasible if an organics collection program is available, since the technology is in place but it needs implementation to fully close the life cycle.

Recently, BASF has launched its Ecovio, a biodegradable plastic using foam. Ecovio is made from BASF’s biodegradable polyester Ecoflex and polyactic acid.

New Ethanol Technology Will Cut Energy Cost

New technology for Ethanol production energy reduction by reducing emissions and improving overall energy balance wwas presented by Interstate Power and Light Co. (IPL), a subsidiary of Alliant Energy Corporation, Harris Companies, a mechanical contracting firm; and AE&E - Von Roll, Inc., a technology provider of steam generating systems. Currently the licensor for the patent is managed by FCStone Carbon, LLC. The technology is claimed to enable producers to produce Ethanol at significant cost reduction which will place the owners at great competitive advantage.
Typical process of Ethanol production

The new patented technology utilizing Ethanol in the product stream for the steam generation cutting the fuel gas consumption by 50% which save energy and reduces plant emissions.

As ethanol production has more than doubled in the past eight years, energy balance is a key issue. This technology will help producers reduce energy consumption while increasing the efficiencies of ethanol production.

Energy costs for a typical 50-million-gallon-per-year ethanol plant represent approximately 20 percent of the plants total annual operating costs. For every gallon of ethanol produced, 29 cents is spent on natural gas and four cents is spent on electricity.

Analysts are expecting that Ethanol producers will eventually adapt the technology for the cost benefit impact and better environmental image for ethanol plants.

In a separate news: DuPont has announced that it is investing $300 million for biofuels development. DuPont, a US chemical major player is planning to invest US$300 million in biofuels development which includes bio-butanol expansion and cellulosic ethanol technological acceleration development. The investment plan is set to start in the next 12 to 18 months.

Chemical Technology: Methanol to Olefins

What is Methanol to Olefins?
Methanol to Olefins is a technology which can convert methanol to olefins (ethylene, propylene, butylenes, isobutylenes, and heavier olefins). Methanol to Olefins (MTO) technology can be considered as new technology in petrochemical processing since propylene and ethylene are usually obtained through conventional processes such as steam cracking, FCC and other available options.

Chemical Information and Process Technology
The process is to produce selective production of ethylene and propylene from methanol. MTO process converts methanol to ethylene and propylene at nearly 80% carbon selectivity in a fluidized bed reactor. The MTO reaction is exothermic.
Carbon or coke accumulates on the catalyst and must be removed to maintain catalyst activity. The coke is removed by combustion with air in a catalyst regenerator system. Other co-products include very small amounts of C1-C4 paraffins, hydrogen, CO and CO2, as well as ppm levels of heavier oxygenates that are removed to ensure that the product olefins meet polymer-grade specifications.
The ratio of propylene/ethylene product can range from less than 0.8 to more than 1.3. When combined with the Total Petrochemicals/UOP Olefin Cracking process (to be discussed later) to convert the heavier olefins, the overall yields of ethylene plus propylene increase to between 85 to 90 % and propylene/ethylene product ratios of more than 1.5 are achievable. MTO is part of a two-step process, which converts natural gas or coal to methanol followed by the conversion of methanol to light olefins.

Market Information/ Economics
MTO projects are driven by the desire to monetize natural gas or coal and the market demands for ethylene and propylene and their derivatives. Stranded natural gas prices are generally independent of crude oil and naphtha market prices so MTO provides another means for olefin derivative producers to diversify the cost structure for their feedstocks. MTO can provide much lower costs of production and higher returns on investment than naphtha crackers especially when crude oil market prices are high. MTO can also provide much lower costs of production and higher returns on investment than ethane crackers using ethane or natural gas liquids extracted from natural gas at prices above $3 to 4 per million Btu (e.g. North America). MTO plants can be located near or integrated with a methanol plant or they can be located separately with a methanol plant located near the gas source and the MTO plant located near the olefin markets or olefin derivative plants. In either case the methanol plant is located with access to low cost natural gas or coal. If there is local demand for a portion of the light olefins or their derivatives, then it can be desirable to locate the MTO unit at the same location as the methanol unit. If all of the light olefins or their derivatives are to be exported, then it may be preferable to ship methanol to an MTO unit that is located near the olefin or olefin derivative markets.
