Cascadia CleanTech Accelerator Announces 2019 Cohort

Selected startups are developing new clean technologies ranging from concrete made from hemp and coatings that boost solar panel efficiency, to EV retrofits for cargo fleet vans and a conversion process for plastics that could reduce marine litter

SEATTLE and PORTLAND, Ore. (June 6, 2019) -- The Cascadia CleanTech Accelerator today announced its 2019 cohort of eight Pacific Northwest startups that will receive cleantech-specific training in business planning, customer discovery, manufacturing and planning for environmental and social sustainability over the next 15 weeks.

Hosted by VertueLab in Portland and CleanTech Alliance in Seattle, the Cascadia CleanTech Accelerator is now in its fourth year helping early-stage cleantech startups speed their technologies to market through curriculum, mentorship and business connections (last year’s cohort pictured, above).

"At VertueLab, we are focused on reversing the climate crisis by funding and supporting technology innovators and entrepreneurs, so we're excited to be helping the women and men in this cohort who are innovating tomorrow's solutions," said David Kenney, president and executive director of VertueLab.

Participants in prior cohorts include Wheyward Spirit, a Eugene, Ore., startup that's converting excess whey and water from cheese making into vodka, and Sironix Renewables, a Seattle producer of plant-based surfactant ingredients that enable detergents to be made with fewer harmful chemicals and at higher concentrations.

"Previous startups in the Cascadia CleanTech Accelerator have gone on to make national headlines, which is not only inspiring but also demonstrates that early mentoring and support in a startup's development is critical to success," said J. Thomas Ranken, president and CEO of CleanTech Alliance.

The startup teams from the 2019 cohort will be part of the CleanTech Innovation Showcase on June 24 in Seattle, and the accelerator program will culminate at the VertueLab Impact Summit in Portland, Ore., on September 13, 2019, when the teams will exhibit their technologies.

The eight startups of the 2019 cohort are:

  • BlueDot Photonics (Seattle, Wash.) – Developer of an efficiency-boosting coating for solar panels.

  • Hempitecture (Ketchum, Idaho) –  Producer of hempcrete insulation blocks and other services for hempcrete construction.

  • Hexas Biomass (Olympia, Wash.) – Producer and distributor of sustainable, non-wood biomass that can supplement or replace wood in multiple applications, including energy, composite/engineered materials, pulp and paper, and other applications that traditionally use wood.

  • Maxwell Vehicles (Seattle, Wash.) – Maker of electric vehicle retrofits for fleet cargo vans.

  • SCW Technologies (Seattle, Wash) – Developer of a patent-pending technology that uses water to convert plastic to its original petro-chemical state, providing a cost effective solution to plastic marine litter and the landfilling of end-of-life-plastics.

  • SHB Power Plan Engineering (Portland, Ore.) – Developer of a biomass power system that produces carbon-neutral co-generation power from otherwise intractable fuels, such as sugarcane bagasse and other agricultural waste products.

  • Stark Street Materials (Portland, Ore.) – Producer of lightweight, nontoxic and recyclable radiation shielding garments.

  • Sustainabilist (Portland, Ore.) – Developer of a process improvement platform specifically designed for the HVAC and solar trades that small business owners can use instead of an outside consultant.
