Advances in manufacturing (faster, cheaper, smarter) don’t always result from one big technological breakthrough: much of the work of innovation involves building on what people have accomplished before.

Both P2 Science and HT Materials Science have drawn on their own inventions in chemistry to create cleaner and greener cosmetics and to make heating and air-conditioning systems more efficient and less thirsty for water. And since HT counts factories among its clients, future occupants of this list may rank among the beneficiaries of its work.

5. HT Materials Science
For identifying an additive that makes HVAC systems more efficient

The digital revolution giveth, and the digital revolution taketh away: On the one hand, smart technologies are improving energy efficiency; on the other, data centers and crypto-mining operations and fulfilment operations consume a massive and growing amount of energy that’s expected to double by 2030. About 40% of that consumption is attributable to energy required to keep operations cool.

Dublin-based startup HT Materials Science doesn’t make heating/ventilation/air-conditioning systems, but it does make the HVAC hardware already installed at commercial and industrial sites significantly more efficient. The company accomplishes this with its proprietary drop-in additive called Maxwell, which suspends microscopic particles of aluminum oxide in water or a mixture of water and glycol to improve heat transfer. Adding just a tiny bit to an HVAC system’s water or water-glycol mix helps juice efficiency by up to 20%.

HTMS has strategic partnerships with a number of prominent companies, including Regeneron and Saudi Aramco, and in May 2024 it was accepted into Amazon’s Sustainability Accelerator to deploy Maxwell at a trio of fulfilment centers in the U.K.
