Re: How green is blue hydrogen?
Kevin Janak <kevjan43@...>
Interesting. I think we are talking about two different processes for making hydrogen here. What is described as "blue hydrogen" appears to me to be hydrogen made from the combustion of methane (CH4) with Oxygen (O2) to make carbon dioxide (CO2, a greenhouse gas) and hydrogen (H2). The chemical reaction is: CH4 + O2 = CO2 + 2H2. I agree that this is not a beneficial solution to climate change, as carbon sequestration is really just a mitigation practice. The next process is hydrolysis, which involves using electricity to hydrolyze water to make hydrogen (H2) which could be a viable solution to reducing greenhouse gases, but it currently appears to require a significant amount of energy in the form of electricity. Personally, I would think that having each vehicle hydrolyze its own water for combustion (which would then make water H2O and return for the hydrolysis cycle) would be the ideal way to provide power. Imagine going to the water station to fill up your vehicle fuel tank with water. My two cents. Kevin Janak

Blue Hydrogen is discussed briefly by Stanford Professor Mark Jacobson in the webinar linked to below. The main topic was Carbon Capture and Direct Air Capture as false climate solutions. As he put it in his title, they "cause more damage than good." There is a second speaker, an ecologist, who addresses the environmental justice impacts of CCS and DAS. The section on Blue Hydrogen is brief but totally data based. Here is the link: https://vimeo.com/586083689 Roger Knudson, Ph. D.

My father-in-law recently got a new vehicle. They could have afforded a model Y, but went with a Toyota Highlander hybrid instead, which isn’t horrible. I talked to him and he said instead of electric, he wanted hydrogen. He wanted to install a hydrogen fueling station in his garage. I said if he did that, it’d be the first hydrogen fueling station in the state lol.

August 14 Meeting Reminder
Dan - NTREG Advisor
While we in America continue to increase the quantity of solar electric energy systems being installed .. we often overlook the fact many people in other countries don't have access to any electricity at all. Our August 14, 2021 presentation is an introduction to Okra Solar and their international projects installing solar energy for citizens in other countries who - until now - have had little to no access to electricity.
Date: Saturday, August 14, 2021 Time: 10:00 am - 12:00 noon Location: ON LINE. Click HERE to Join our August 14 meeting. Direct Address: https://us02web.zoom.us/j/7917514794?pwd=TmhyRjhEdVZSb0o2MDA1QVdzNExadz09 Meeting ID: 791 751 4794 Passcode: 456123 One tap mobile: +13017158592,,7917514794#,,,,*456123# US (Washington DC) +13126266799,,7917514794#,,,,*456123# US (Chicago) Presentation: "Power to the People: Mesh Grids for the Last Mile" Presenter: Afnan Hannan, Co-Founder & Chief Executive Officer of Okra Solar About our Presenter: Afnan was named to Forbes "30 Under 30 Asia 2021" for enabling utility companies in Cambodia to energize rural villages that aren’t connected to national utility grids. This recognition follows a long list of awards and accolades given to Okra Solar. Okra Solar was founded in 2016 and is headquartered in Sydney, Australia. NTREG meetings are free and open to the public! Everyone welcome!

Re: Ground Source Heat Pump installer
By the way, Dallas Demolition is nearly finished tearing down my old energy inefficient house. They should have the rubble removed by Friday. Cam at: Next week the new house site prep will begin. The GSHP (Ground Source Heat Pump) contractor will bring in their drilling rig and install the geo wells. Then another company will inject soil stabilization treatment into the area of the new foundation to reduce soil expansion/contraction due to water. Then the post-stressed foundation work begins. — Bill

Re: Ground Source Heat Pump installer
I will try to remember to post here when the Volvo ECR305CL demolition excavator starts knocking down my old house later this week. I will also try to catch the geothermal well drilling rig when it's active. The link I gave only shows the live image, but I have 10 days of archived video available at the Nest website. So I can create a "greatest hits" reel showing machinery in action! — Bill

Some shipping lines tried deploying sail (huge spinnakers) when wind was favorable. Don’t know where that went. I suspect it required more crew who could do it and bunker oil is cheaper

Re: Ground Source Heat Pump installer
Excel Geothermal is going to install the GSHP system in the new house I’m building this summer. See: I’m getting a ClimateMaster system (made in Oklahoma City) with the highest available Energy Star EER rating. Hot water will be from the desuperheater used by the system. My project will use vertical wells, which require a drilling rig. That’s easy for my project, since my old house and foundation will be demolished by Dallas Demolition later this week, so the geothermal drilling rig will have easy access. The progress (or lack thereof) can be seen on my old house demolition & new house construction webcam at: — Bill
