Gradient: Vince Romanin
Play • 1 hr 15 min

“If the next 4 billion ACs are all heat pumps, they can also decarbonize heating while we’re expanding access to AC. If they have low carbon refrigerants we can solve the refrigerant problem.  Lastly, if we make sure they’re all smart and WiFi connected we can help modernize the grid at the same time and have more solar and wind on the grid.”  -Vince Romanin, Co-founder and CEO of Gradient.  

Vince Romanin is the CEO of Gradient (@GradientComfort), which is on a mission to cool the world sustainably.  Gradient plans to achieve this by increasing the efficiency of heating and cooling systems, removing harmful refrigerants, and electrifying the heating sector, all of which combined can offset about 2 GtCO2/year, or 7% of our total emissions today. Gradient’s first product is an easier-to-install and easier-to-use heat pump that is quiet and gives you your window back.

This episode is brought to you by ☀️Yotta Energy !  We all know energy storage is key to deploying renewables at scale. I’ve seen many energy storage solutions for commercial buildings over my years in climate tech, but none as impressive as Yotta’s.  

Yotta Energy’s unique "PV-Coupled" ecosystem of solar+storage solutions simply integrates within the standard solar installation process. Even better, their integrated storage technology can enable up to 60% more solar to be deployed on commercial buildings.  With commercial buildings consuming 35% of US electricity that means Yotta is making a serious dent in CO2 emissions. With the electrification of everything revolution underway, Yotta Energy is poised to meet the growing demands of electrification by sizing solar+storage resources to recharge electric vehicles as they future proof buildings into distributed energy sites powering the grid of the future.

This episode is also brought to you by 💎 Aether Diamonds.  If you’re planning to propose, or purchase a timeless gift for your partner, I couldn’t think of a better purchase than Aether Diamonds.  

Aether Diamonds are the world’s most sustainable diamonds, and the only diamonds that are actually GOOD for the planet!  Aether creates the world's first positive-impact diamonds made from captured CO2.  In fact, every carat of Aether Diamonds offsets your personal carbon footprint for over a year.  These are 100% real diamonds with a real impact. They’re some of the highest quality diamonds you can buy, and are certified by IGI, the world's largest independent laboratory for testing and grading gemstones and fine jewelry.

Now you’re no longer stuck having to choose between mined and regular lab-grown diamonds, both of which harm the environment.  Aether offers the only truly sustainable diamonds on the market, requiring no ethical or environmental trade-offs… in other words, they're the only guilt-free diamonds available in the world.
