The CleanTech Alliance Lunch Series presents notable clean tech executive speakers for a monthly conversation followed by networking with cleantech industry leaders from across the region. A different speaker and topic is presented on the second Wednesday of each month (12:00 p.m. to 1:30 p.m.) from September 2025 through October 2026 (except May, November, and December).
PFAS in the Rain: Solutions for the Ultra-Shorts
Join us on Wednesday, October 8, 2025, from 12 PM – 1:30 PM PST, for this exploratory lunch conversation and networking event at the Perkins Coie office downtown Seattle.
This month’s luncheon will expand on the content from the September 24th webinar, PFAS in the Rain: How Adopting Natural Refrigerants Can Reduce Risk and Grow Our Clean Energy Economy. We’ll be joined by a panel of experts discussing how to remove PFAS from the environment, prevent future PFAS emissions, and galvanize a better statewide testing regime in Washington.

Moderator:

Andy Baker, Owner and Project Manager, YourCleanEnergy
Andy is a registered professional engineer and owner of YourCleanEnergy consulting based in Seattle. He has significant experience in the financial evaluation and design of commercial sized CO2 heat pump systems which are integrated into existing and new facilities. He lived and worked for 18 years in Alaska and has been based in Seattle since 2018 where his work has expanded into the shaping of regulations and policy regarding heat pump refrigerants. Andy is a regular presenter and speaker on the topic of natural refrigerants and the long-term financial and environmental benefits they can provide to commercial and institutional clients for clean heating and cooling. Andy’s work focus since 2008 has been on design of heat pump systems for large facilities in the Pacific Northwest, and for ocean source district heating in coastal Alaska. His key natural refrigerant project is the design of a seawater source 80-ton trans-critical CO2 heat pump system with heat recovery to offset an existing 500 KW electric boiler used for space, domestic hot water, and outdoor slab heat. Additionally, Andy has partnered with ATMOsphere for the past three years to identify both opportunities and obstructions that exist in the US market for natural refrigerant heat pumps. He has also been working to build a coalition of businesses and organizations that are dedicated to growing the Natural Refrigerant heat pump market in Washington State and are committed to shaping common sense regulations and policy to advance this growth.
