Aquaflow: next-gen biofuels a commercial reality

Positive news this week from the Nelson-based algae company Aquaflow whose fortunes we have followed on Hot Topic over the past three years. I last reported on them in August 2011, when they had signed an agreement for joint testing and evaluation with Texas-based CRI Catalyst Company (CRI). Now they have announced a full technology cooperation agreement with that company which they believe leaves them poised to make refining next generation biofuels a commercial reality in New Zealand and in overseas projects within the two to three years it takes to build a refinery.

That’s big news if it comes to fruition. Director Nick Gerritsen says: “We should be able to produce renewable hydrocarbon fuel that is equivalent to fossil fuel at a cost that is highly competitive with the current per barrel price of crude oil.” He adds that New Zealand could turn its biomass into enough carbon-neutral biofuel to meet its renewable fuels requirement within ten years.

Hansen’s righteous cause

The latest communication from James Hansen to his email list this week was a sharp reminder that the New Zealand Government’s commitment to the pursuit of unexploited fossil fuels is part of widespread malpractice.

The global stampede to find every possible fossil fuel is not being opposed by governments, no matter how dirty the fuels nor how senseless the energy strategy is from long-term economic and moral perspectives.

The specific case that Hansen focuses on is the Alberta tar sands. He has some chilling statistics.

Asking the hard questions

I watched TVNZ’s Q+A on Sunday with dismay.  Phil Heatley, the Minister of Energy and Resources, was interviewed about the New Zealand government’s intention to increase oil, gas and coal exploration and mining. The emphasis of the interview was on the environmental issues, yet not a word was said about greenhouse gases or climate change. The environmental questions discussed were not unimportant, but they were easy for the Minister to swat away with talk of how Taranaki’s environment has not been seriously impacted by drilling, of how fracking is confined to suitable deep rock formations, of how careful the Government is to balance the interests of the environment against the economic gains to be had from the exploitation of our mineral resources, and so on.

What would the Minister have said if he was asked how the Government can justify pushing for increased fossil fuel exploitation in the light of the global warming to which the burning of these fuels will contribute?  I have a fair idea what he would have said, but he wasn’t asked. The fact that he wasn’t bothers me as much as his likely answer if he had been. Because it seems to indicate that the overwhelming question is either not perceived or deliberately avoided by journalists running a major current affairs programme.

Cuckoo cocoon (Prat Watch #5.5)

Something stirred inside the carefully cultivated cocoon of ignorance at Richard Treadgold’s Climate “Conversation” blog, but I don’t think it was the butterfly of understanding preparing to inflate its wings. Something much more subterranean, I suspect. Needled by my post about said cocoon (namely, Treadgold’s insistence that “global warming has not happened for about 15 years, unless you take a micrometer to the thermometer“), RT issues a bold challenge: Well, where’s your evidence, Renowden?

He heads his post with a graph lifted from JunkScience (that well known purveyor of same), showing the HadCRUT3 monthly temperature series from 1978 to date. Amusingly, Treadgold makes an error before he even begins the meat of his diatribe. The caption he provides to the graph includes this:

The graph that proves no significant warming for about 15 years – since about 1996. Measured by satellite, not the unreliable hand of man.

The HadCRUT3 global series is most assuredly not a satellite generated temperature record. But we’ll let that pass, shall we, and take a quick canter through an answer to his challenge. I shall ignore Mark Twain’s advice just this once, in the hope that some light may shine in to the dark corners of his misunderstanding.

Weakened NZ ETS not responsible economic management

Tim Groser, the new Minister for Climate Change Issues, is adamant in his defence of the intention to further delay bringing the agricultural sector into the Emissions Trading Scheme beyond the current date of 2015 unless there are adequate abatement options open to them by then and unless other countries step up to the mark with mitigation measures.  His remarks on Morning Report on Thursday made it clear that the interests of the overall economy were more important than mitigation of the 0.2% of the global greenhouse gas emissions that New Zealand is responsible for.  He spoke of the difficulty of managing the economy through tough times.
