Bill Gates venture backs effort to bring aircon startup to market

(2022/07/29)


A fund founded by Bill Gates is leading a $20 million investment round into an aircon startup which promises to slash the carbon impact of keeping people cool on a heating planet.

The cash is designed to get to market aircon units from Blue Frontier, which bases its approach on removing moisture from the air and doing the most work when electricity is cheap and more likely green at source. The company claims to reduce the greenhouse gas emissions from aircon by 85 per cent.

Gates' Breakthrough Energy Ventures is joined by 2150 Urban Tech Sustainability Fund and VoLo Earth Ventures in investing in Modern Niagara, the commercialization partner backing Blue Frontier in the hopes of bringing the technology to market.

The problems of aircon in terms of climate change are two-fold. Not only is the electricity needed for air cooling a major source of carbon emissions – [2]as much as 4 percent according to some measures – as carbon emissions warm the planet, but at the same time, more people also require aircon and installed aircon is worked harder, more often.

To try to crack this spiralling impact, Blue Frontier has developed a technology which relies on liquid desiccants – substances which remove moisture from the air. The air is subsequently cooled by indirect evaporative cooling.

The [5]first step in the Blue Frontier process is to concentrate its proprietary liquid desiccants in a salt solution, so it is available to produce air conditioning, a process also known as regeneration. Heat is used to concentrate the liquid desiccant, [6]releasing water [PDF] that is recovered for later use to drive air conditioning.

[7]

Crucially, after the regeneration stage, the solution is available to cool air at any point afterwards. In this way, it is designed to store "potential cooling" and thereby take advantage of cheap green electricity and avoid using costly, more carbon-intensive electricity when demand is higher. It may also help avoid brown-outs which have become worryingly common in the hot Californian summers.

The system does rely on refrigerants and compression in the same way as conventional aircon and refrigeration, but they come into play in a different step in the process. Blue Frontier uses refrigerants in a heat pump to regulate salt concentrations in the desiccant. Because they are housed within the system, engineers were free to safely select mildly flammable refrigerants. It requires less refrigerant than a conventional system, and the refrigerant it uses has a lower impact on greenhouse gas emissions, the company says.

"The refrigerant and refrigerant-carrying equipment never meets air entering the building or the interior of the building," Betts [12]told CNBC. "This gives us an enormous advantage to use readily available refrigerants that are mildly flammable, without putting at risk the safety of the people in the building."

The combination of greater efficiency, an ability to smooth out demand on the grid and the use of less impactful refrigerants creates a combined reduction in greenhouse gas emissions of between 85 and 87 percent, the company estimates.

Betts said the first products for commercial buildings will be available in 2025, following rollout to a few pilot sites. ®

Lest we forget...

bombastic bob

The theory of 'Man Made Climate Change' caused by CO2 is a MYTH, since CO2 is so *horrible* at being a greenhouse gas. GH gasses are supposed to stop black body radiation from leaving the planet+atmosphere at night (which is how the planet cools), thereby keeping the earth warmer. But CO2 only affects a TINY fraction of the IR energy. MOST of that energy is kept on the planet by WATER ("the other greenhouse gas"). Additionally CO2 is at equilibrium between rain, plants, and the temperature of large bodies of water. Hockey stick graphs that have tracked CO2 since 1958 and TRIED to claim the CO2 is causing the warming NOT ONLY fail to take into consideration that warmer water (from temp cycles and active volcanoes) RELEASES CO2, but MOST of the numbers since 1958 were apparently tracked at MAUNA LOA, an ACTIVE VOLCANO in Hawaii (and YES, volcanoes gas TREMENDOUS amounts of CO2, even from soil [for miles around them], with MOST of the world's carbon existing in the MANTLE, where LAVA comes from).

Still, energy/cost efficient air conditioning IS a good idea. If I owned the place I live in, I'd try to set up smart fans and dampers in the attic, trap heat when cold, ventilate when hot, use prevailing wind with rooftop spinners, things like that. I mean we ALL want to save MONEY, right? So WHY CAN'T "THEY" JUST SAY "LESS EXPENSIVE" INSTEAD???

If the science is too difficult for you, maybe just don't go announcing it to everyone. You're embarrassing yourself and honestly it's making a bunch of us feel a bit awkward just being in the same community. There's nothing wrong with being a simpleton, but announcing it to the world by yelling in all caps about things that are evidently far beyond your grasp is right at the top of the cringe scale.

In fairness, you may still be getting paid to post stuff like this- it's possible that you're evil rather than stupid - but I don't know if there's the ROI on it even for BP or Exxon to justify maintaining that astroturf by this point. These claims are almost as fossilised as the fuels they are selling us to help extinguish our grandchildren.

Re: I'm either scientifically illiterate or evil, you decide

bombastic bob

eh, I do my posting for free. It's a public service!!! [gotta get the word out]

By the way - the science of CO2 should be obvious to someone who took college chemistry. Or high school chemistry. Just study what an equilbrium reaction is. if you have EVER done a phosphate titration, you'll understand this, too. If you have NOT done anything like that, well, that explains a lot...

I made this graphic I have been posting a lot online, explaining in detail what I mentioned in my original post in this thread. It has charts and explains things more. You would have no trouble finding it if you are interested. It has science in it. Have fun refuting it. ( You can see it in #ClimateChangeHoax )

Re: I'm either scientifically illiterate or evil, you decide

Charlie Clark

Some of us have done more than high school chemistry and understand why your purported science isn't.

CO2 as a greenhouse gas is a theory that fits the facts quite well. Whether it's the only one, or if the causes are not all man made is beside the point if we can see that higher water temperatures correlate increasingly well with extreme weather events.

Whether it's as part of an attempt to reverse the increase of atmsopheric CO2, or simply to reduce our dependency on energy sources we don't control, I don't see what's wrong with trying to reduce our energy use and switching to renewables.

Re: Lest we forget...

The Man Who Fell To Earth

The "hockey stick graph" is universal at all CO2 monitoring stations all over the world.

Thinking you are the first to think of a possible problem with data collection in a field you have no expertise in is the definition of hubris. To then fail to consider that there's a reason the Mauna Loa is fit for purpose and use your ignorance to invalidate (in your mind) and entire planet's data collection is psychotic, not just scientifically illiterate.

Re: Lest we forget...

It's a complete myth - hoax even - that volcanoes emit huge quantities of CO2 and that they have any significant part to play in climate change.

The fact that this is easily researched and the quantities of CO2 emitted in an eruption easily established just shows what a complete load of cobblers you are talking - to the extent that any sane person has to question absolutely anything else you have to say on the subject. An eruption of a volcano adds a tiny fraction of 1% of human's CO2 output to the total.

Seriously, go and do a little research and then come back and quote your sources to justify your claim. Or maybe even question why you are such a diehard climate denier clinging to such provably false facts.

Smoothing of use rather than cost??

jmch

The more appliances such as these aircons, electric cars, domestic heat pumps etc can adapt to consume 'cheap' electricity, the smoother the consumption curve will be, until you will basically have a flat demand, and no 'cheap rate' electricity - at least not in the sense we now know it where night-time electricity is cheaper because of reduced demand. Instead what will probably happen is that the cost of electricity will depend almost totally on available supply rather than demand. This in turn means that when intermittent sources (wind / solar) are plentiful, prices will be low, which in a subsidy-less world would mean that wind/solar become less economically feasible to operate.

That in turn means that pricing will be being updated 'on the fly' (and appliances will be following suit). With mass adoption, that could lead to situations where the 'clever' appliances are all dumbly switching on at the same time as electricity gets cheap, electricity demand spikes as do prices, and said dumb smart appliances switch off again. Rinse and repeat. Only half joking there... there needs to be a bit more additional smarts into these 'smart' appliances. To our advantage, it will be decades before these appliances become commonplace enough to trigger grid problems.

And the great long-term benefit (assuming no stupid smart behaviour as above) is the smoothing of demand, which would reduce stress on the grid infrastructure.

Re: Smoothing of use rather than cost??

bombastic bob

Yes - the higher cost of electricity is usually due to varying demand.

Nuclear power has to maintain relatively constant power levels due to the physics.

Steam plants burning fossil fuels can more readily adjust to demand, but it is more economical to run them at relatively high power levels all of the time, and it takes quite a bit of time to shut them down and start them back up again.

Gas turbine and Diesel "peaker" plants are designed to quickly handle varying demand but since they only run some of the time (and often at lower efficiency, as I understand) the electricity they produce is MORE EXPENSIVE.

And when the wind does not blow, or there is overcast (or night), "green" power isn't going to help much.

The only practical thing left for varying demand is hydro-electric, and there are only so many dams.

So CONSTANT DEMAND (especially using offpeak power) IS a great idea, if you can offset usage from peak times that way. In my case the utility is charging differently for different time slots, so I run dishwashers and laundry and (sometimes) A/C during off-peak whenever I can. Not always possible, but I try. It saves money. If this were AUTOMATIC somehow, it would save money and ALSO even out demand somewhat.

Makes total sense.

Re: SmOoThINg oF uSe RaThEr ThAn C0$$$t??

adam 40

Apart from Hydro, maybe we could harness some other type of potential energy?

I was thinking, 7 billion humans times the weight of their middle finger, hovering 2 inches above the shift key???

Anyhow, joking aside, the storage of this renewable stuff to smooth out the peaks is an issue.

Or else - only use it when you have it? So - no smelting or factories running except when the sun is shining or wind blowing? Maybe good old market pricing of electricity will sort that one out though.

Lastly, with this salty idea for air conditioning - what happens if it turns out cool the next day? Your investment in electricity is wasted. And - why do we need anything better than freezing and melting water? it seems like an invention for invention's sake.

aircon

Bill Gates and air CON sounds like a plan to deprive people of air... After all Bill Gates supports depopulation.

Re: aircon

Is there anything wrong with lowering the population through passive means? For example, lowering birth rates. It's probably the surest way to fight global warming.

Eugenics was based on pseudoscience pushed by the American medical community:
