Part II of the interview with Canadian Chemical Processes Expert Paul Martin. In case you have missed it, in Part I Paul talked us through the, rather inconvenient facts about hydrogen as a means to export energy for Australia and why that is a rather far fetched idea. Here is a link to Part 1 of the interview. In this episode Gunnar and James talk about:The best uses for hydrogenHow we will best decarbonise our livesWe learn about carbon taxes and how Canada has implemented them quite successfullyObjections to carbon taxesElectricity prices in AustraliaWhat fuels we will use for land transport in the futureAlso for air traffic and long distance shippingWhether we will be able to use the existing gas infrastructure (terminals, pipelines, pumping stations etc.)On top of all that Gunnar took the opportunity to show his terrible knowledge of fairly recent Australian political events. James came to the rescue. Reach Paul at https://spitfireresearch.com/https://www.linkedin.com/today/author/paul-martin-195763bThe articles Paul Mentions during the episode: The Myth Of Hydrogen Export: https://www.linkedin.com/pulse/myth-hydrogen-export-spitfire-research-incWhat are the Energy Solutions? https://www.linkedin.com/pulse/what-energy-solutions-paul-martinHydrogen Science Coalition www.h2sciencecoalition.comThe episode was recorded on 17 April 2024Contact: bts@4pillars.com.au https://www.linkedin.com/company/below-the-surface-podcast The necessary disclaimer: The views, thoughts, and opinions expressed in this Podcast are the speakers’ own.

Gunnar and James are talking to Paul Martin, a Canadian Chemical Process Development Expert and tireless advocate for a fossil free future. This first part of a two-part episode looks into whether the claims that Australia has a future as a new energy provider to the world via Hydrogen exports are based on reality or wishful thinking. Paul Martin calls a lot of it #hopium - that should give you an indication of what Paul will be presenting.Link to Part 2 of this chat.Reach Paul at https://spitfireresearch.com/https://www.linkedin.com/today/author/paul-martin-195763bThe articles Paul Mentions during the episode: The Myth Of Hydrogen Export: https://www.linkedin.com/pulse/myth-hydrogen-export-spitfire-research-incWhat are the Energy Solutions? https://www.linkedin.com/pulse/what-energy-solutions-paul-martinHydrogen Science Coalition www.h2sciencecoalition.comThe episode was recorded on 17 April 2024Contact: bts@4pillars.com.au https://www.linkedin.com/company/below-the-surface-podcast The necessary disclaimer: The views, thoughts, and opinions expressed in this Podcast are the speakers’ own.

Our guest on this episode is Adrian Heggie. Over the past decade Adrian has developed an amazingly simple method for the delineation of sub-surface hydrocarbon plumes (chlorinated or not) by measuring the aboveground concentration these plumes cause. His method is fast, accurate, inexpensive and most of all, does not require any invasive ground work. If you think this sounds too good to be true, this chat will convince you otherwise.Adrian showcased his research at the recent Chlorinated Hydrocarbon Symposium held in Adelaide. Among the audience was Gunnar, who, like many others, was intrigued by the presentation. In this chat the two of them delve into Adrian's research and shed some light on how hydrocarbon contamination reaching the surface can be captured and measured (not a good pun, but still intended).https://au.linkedin.com/in/adrian-heggie-b7767336The episode was recorded on 28 March 2024.Contact: bts@4pillars.com.au https://www.linkedin.com/company/below-the-surface-podcast The necessary disclaimer: The views, thoughts, and opinions expressed in this Podcast are the speakers’ own.

In this episode, we delve into the question of dangers lurking in unsuspecting areas like our backyards and public parks. Join Gunnar and James as they discuss with researcher Ana Serra the findings of her study into asbestos exposure from seemingly mundane activities like lawn mowing or soil disturbance during landscaping or Council maintenance work.  How many respirable fibres get released  when a lawn mower drives over bonded asbestos fragments on the surface of a site? What happens when the spinning blades hit a fragment and the fragment gets propelled out?What happens when you do all this during a record breaking dry spell in hot and dusty Australian summer conditions ?Is there a difference in exposure levels when you compare members of the public who are nearby the work areas to the exposure of the trades people doing the actual work?What measures can be taken to avoid the release of respirable fibres during those activities?How do you best approach the subject with worried staff members and the public? The 2019 study was funded by Liverpool City Council. Investing in research is often a challenging decision for local councils, but guess which Council's rate payers are sitting rather sweet now during the Mulchgate panic and enjoy the fruit of the research?  Huge credit to Liverpool City Council for taking the lead and funding the research.  What a great investment it turned out to be.This episode was recorded on 15 March 2024.Contact: bts@4pillars.com.au https://www.linkedin.com/company/below-the-surface-podcast The necessary disclaimer: The views, thoughts, and opinions expressed in this Podcast are the speakers’ own.

James twisted Gunnar's arm and convinced him to record a podcast about issues around policies in the environmental industry. Why does the EPA quietly make updates to definitions but does not tell anyone about it? Why are there 'internal policies' that are not written down that the EPA and some local governments enforce willy nilly. Why is there no central spot for policy updates in our industry?They also talk about proposed changes to the POEO Act (and before you get all excited, it is not what you think or hope for) and Gunnar proudly relives a meeting with the Lord Mayor of one of Sydney's biggest Councils and - clickbait alert - you will not believe what he actually said to him.Gunnar and James of course put their usual unusual spin on things so it is definitely worth listening to.Contact: bts@4pillars.com.au https://www.linkedin.com/company/below-the-surface-podcast The necessary disclaimer: The views, thoughts, and opinions expressed in this Podcast are the speakers’ own.

Sydney is still in the grip of an asbestos panic. In this episode we sit down with Philip Hibbs, one of the ultimate OH/S and asbestos experts in Australia. We chat about what he calls "Mulchgate", the actual risk to humans posed as a result, other risks humans are exposed to, we bag all sorts of regulators and organisations for their lack of leadership and we are having a fair bit of fun doing so. Find out lore about Phil Hibbs at https://hibbs.com.au/ and https://au.linkedin.com/in/philip-hibbs-096a8aThis episode was recorded on 24 February 2024Contact: bts@4pillars.com.au https://www.linkedin.com/company/below-the-surface-podcast The necessary disclaimer: The views, thoughts, and opinions expressed in this Podcast are the speakers’ own.

Bonded asbestos fragments have been found in mulch in a brand-new park in Sydney's suburb Rozelle. The ensuing panic in the public, associated finger pointing and running for cover by contractors, suppliers, regulators and of course politicians was as expected as it was to a degree amusing.  Gunnar and James simply had to talk about this.  The episode was recorded on Thursday 8 February 2024.The Guardian Article we mention: https://www.theguardian.com/australia-news/2024/jan/29/asbestos-nsw-findings-watchdog-epa-contaminated-soil-childcare-centres-schools-parksThe Mulch Order: https://www.epa.nsw.gov.au/-/media/epa/corporate-site/resources/wastegrants/rro16-mulch.pdf The ENM Order: https://www.epa.nsw.gov.au/-/media/epa/corporate-site/resources/waste/rro14-excavated-natural-material.pdfContact: bts@4pillars.com.au https://www.linkedin.com/company/below-the-surface-podcast The necessary disclaimer: The views, thoughts, and opinions expressed in this Podcast are the speakers’ own.
