Improving The Performance Of Solar Thermal Power

The US Department of Energy granted a US$1.37 billion loan guarantee to Brightsource Energy last week which could help clear the way for over 15 gigawatts of solar thermal power projects in California. Brightsource built a pilot plant in Israel to prove their technology and has tested it over the past 18 months. Their flagship Ivanpah project in California got a big boost when construction giant Bechtel agreed to build the plant.

Solar thermal (often referred to as CSP) is a way of harnessing the largest source of energy available to us, so in this post I'll have a look at the upswing in interest in the technology in recent years and look at some of the approaches being pursued to make it economically competitive with coal fired power generation.

Australia's Renewable Energy Future Report Released

The Australian Academy of Science have released their report into Australia's Renewable Energy Future - Australia's Renewable Energy Future (pdf).

Peak Oil And The Tea Party Movement

Time Magazine recently had an article (Why the Tea Party Movement Matters) that looked at the latest manifestation of populism in the United States, with widespread discontent at the state of the US economy and the US political system, particularly the lack of transparency evident in many government initiatives ranging from the bail-out of the financial system to proposed changes to healthcare, along with discontent about costly wars in the middle east that seem to be never-ending.

The "tea partiers" remain a somewhat disorganised grass-roots movement (albeit one with concerted efforts by the conservative establishment to pull their strings) and they are showing some signs of adopting the tactics of the hippie counterculture of past decades and simply dropping out of mainstream society (see this piece on the "Rippies" for some background), but they do have the potential to grow as a result of a number of problematic trends affecting the western world in general and the United States in particular.

The graph below shows a possible scenario for average per capita oil consumption in the United States over the next 40 years, which could possibly drop by 90%. In this post I'll have a look at the boost this is likely to give to populist politics and some of the possibilities for addressing this.

The questions we don’t ask: A review of the Australian Energy Resource Assessment

This is a guest post from Cameron Leckie of ASPO Australia.

There does not appear to be any metric by which we could argue that our current socioeconomic systems are sustainable. Despite this, we delude ourselves into believing that business as usual can continue indefinitely. We assist ourselves in this art of self-delusion by failing to ask the right questions or simply limiting the information that we are willing to consider. The recently released Australian Energy Resource Assessment (AERA), particularly the aspects related to oil, is yet another example of how our Government, and the bureaucracies supporting it, are failing to ask the right questions. The unfortunate consequences of this approach implies that Australia will be left with few options to respond to a very challenging set of problems, something that could and should be avoidable.

It should be noted that most of the information in Chapter three - oil of the AERA is good, particularly the assessment of Australia’s future oil production. To the lay person it would appear to be a thorough and accurate appraisal of Australia’s oil situation. The problem’s lie in the nuances, the fallacies, the assumptions and the reliance on a narrow and far from fool proof set of data and projections on the international oil arena. These shortfalls could have significant implications for Australia, so lets take a closer look.

The Australian Energy Resource Assessment

Geoscience Australia and ABARE have released a report into Australia's energy resources, entitled the "Australian Energy Resource Assessment".

The report analyses both traditional (legacy) sources of energy and renewable energy, concluding oil supplies are declining and imports growing, while there is massive unexploited potential in renewable energy sources.

Australia’s oil resources are in decline with remaining crude oil resources estimated to be 8414 PJ (1431 million barrels, mmbbl) and located mostly in the Carnarvon and Gippsland basins. Without significant new discoveries of crude oil, or development of condensate and LPG resources associated with offshore gas resources, or other alternatives, Australia is likely to be increasingly dependent on imports for transport fuels. ...

Australia’s potential renewable resource base is also very large, and includes wind, solar, bioenergy, geothermal, wave and tide as well as hydro resources. Hydro and increasingly wind energy are used in electricity generation. Biomass and solar energy are both being used for heating and electricity generation.

SMH - The city is choking thanks to our idea of transport nirvana

At our behest, successive state governments have been pursuing a magnificent dream, to make Sydney a place fit for cars to be driven on all occasions. Now the Herald-commissioned independent inquiry headed by Ron Christie has exposed that dream for what it is: the wrong tram (forgive me).

Scoop.co.nz - Industry leaders warn of imminent oil crunch

The Green Party is calling on our Government to prepare for a significant oil crunch, in light of an industry led report warning the UK Government about the threat of rising oil prices.

The UK’s Industry Taskforce on Peak Oil and Energy Security has released its second in-depth analysis of the risks to the economy from the end of cheap oil.

The Bloom Box: Initial Evaluations of an Energy Breakthrough

Fuel cell company Bloom Energy made quite a stir over the weekend, with a spot on the CBS "Sixty Minutes" TV program in the United States (The Bloom Box: An Energy Breakthrough? - see the link for the video and transcript).

Bloom has spent 8 years and close to US$400 million developing their product and the company is now leaving "stealth mode" and actively promoting themselves. Fortune also has an article on the company (Is K.R. Sridhar’s 'magic box' ready for prime time?) and the company will be holding a launch event on Wednesday.

Bloom has had a number of companies testing the product in data centres, including Google, FedEx, Staples and eBay.

Is There Enough Food Out There For Nine Billion People ?

Science has a paper on the changes to the current global food system required to support the expanded global population we'll see in a couple of decades time, noting that radical changes to agriculture will be required to support 9 billion people - "Food Security: The Challenge of Feeding 9 Billion People". The full text of the article is available here.

A threefold challenge now faces the world: Match the rapidly changing demand for food from a larger and more affluent population to its supply; do so in ways that are environmentally and socially sustainable; and ensure that the world’s poorest people are no longer hungry. This challenge requires changes in the way food is produced, stored, processed, distributed, and accessed that are as radical as those that occurred during the 18th- and 19th-century Industrial and Agricultural Revolutions and the 20th-century Green Revolution. Increases in production will have an important part to play, but they will be constrained as never before by the finite resources provided by Earth’s lands, oceans, and atmosphere. ...

Recent studies suggest that the world will need 70 to 100% more food by 2050. In this article, major strategies for contributing to the challenge of feeding 9 billion people, including the most disadvantaged, are explored. Particular emphasis is given to sustainability, as well as to the combined role of the natural and social sciences in analyzing and addressing the challenge.

Zero emissions possible for Australia - at $40bn a year

The Age has an article on Beyond Zero Emissions' launch of their "T10" campaign to switch Australia to 100% renewable power in a decade, largely using solar thermal power - Zero emissions possible - at $40bn a year.

Areva Switching From Nuclear Power To Solar ?

French energy company Areva (best known for its nuclear power business) has purchased solar thermal power company Ausra - yet another example of a promising Australian technology company ending up with foreign ownership.

One possible positive interpretation of the news is that Areva are losing faith in the oft-predicted but unrealised "nuclear renaissance" and now see the real future growth opportunities in large scale solar power, with nuclear power (at best) a legacy business.
