The Results

After three months of intense focus, camaraderie and virtual learning, we are pleased to announce Neothermal Energy Storage as the Energy 2021 winner. The company, which offers supplemental electric thermal storage (ETS) systems using salt hydrate to electrify residential boilers and furnaces, won a $25,000 cash prize and a pilot project awarded by Burlington Electric Department (BED). BED also awarded a pilot project to Arc Industries, and Green Mountain Power (GMP) awarded a pilot project to Grid Fruit. Read the recap here.

The challenge

To be part of a competitively-selected cohort of startup ventures that reduce greenhouse gas emissions through energy-related products or services for residential and small business customers. Selection will focus on companies that are entering or currently at a pilot or demonstration stage and planning for scale.

This fifth DeltaClimeVT business accelerator program is designed to accelerate the drive to a zero-carbon future for Vermont by helping Vermont’s utilities increase adoption of clean energy technologies and smart building technologies, and better integrate distributed energy resources. Entrepreneurs will be working directly with Vermont utilities to contribute to Vermont’s 90/50 and Burlington’s Net Zero by 2030 goals.

The program is applicable to startup companies from anywhere in Canada and the United States that see value in piloting their products and services in the Vermont market.

We are particularly interested in services and technologies that have wide potential applicability with rural populations and can enable small businesses, low and moderate-income populations and multi-family building residents to contribute to to the low-carbon economy.

Examples of technologies or services could include but are not limited to:

  • Products or services that create faster and more efficient installation and adoption of energy efficient technologies;
  • Data gathering and energy analytics software that enables greater adoption of energy efficient technologies and services;
  • Smart building technologies such as building controls, smart thermostats, EV charging supply equipment and other devices that could align with utility demand response signals;
  • Localized or micro energy management and storage technologies and related services that enhance end user adoption;
  • Solutions to bring reliable connectivity (e.g. broadband) to rural communities and therefore enable rural communities to adopt behind the meter technologies;
  • Financing models for energy technologies and services (e.g. innovative loans, on-bill financing, heating as a service); and
  • Any other technology or service that enables the reduction of energy use and greenhouse gas emissions in buildings or supports demand management in buildings.

About the Program

The DeltaClimeVT business accelerator program is managed by the Vermont Sustainable Jobs Fund and facilitated by ecosVC. The program is centered around the ecosVC Lens of the Market® ACCELERATED curriculum, designed to ensure participating startups produce a well grounded case for their business and are able to articulate a compelling plan for success to investors.

The program features an extensive online curriculum plus 1-1’s facilitated by ecosVC principals, active engagement with sponsoring Vermont utilities, business mentors, investors and successful venture leaders. Startups must have at least two senior members of their team actively participate in all aspects of the program. The program includes four intensive online sessions (each 2-4 days in duration), weekly assignments and bi-weekly webinars as well as frequent 1:1 engagement with program leaders and mentors. Active engagement and peer-mentoring by participants is an essential part of the program and a final prize of $25,000 was provided to a peer-selected company. The DeltaClimeVT program managers work to ensure that startups in the cohort are non-competitive.

The companies

Andluca Technologies, a Princeton University spin-out, has developed UV-solar-powered smart glass for improving the energy efficiency of buildings. Andluca’s patented technologies can reduce building energy use by up to 40% while significantly enhancing occupant comfort and productivity. Unlike available wired smart glass products – which require major renovation and installation by an electrician – Andluca’s wireless smart glass can be installed quickly and non-disruptively. Andluca was established in 2017 following over 12 years of research on light-responsive materials and films by Professor Lynn Loo and her team at the Organic and Polymer Electronics Laboratory at Princeton University. New Jersey

ARC Industries designs and manufactures vertical axis wind turbines. The company’s new cutting-edge turbine design addresses the many issues that have traditionally plagued small wind turbines. It is ARC Industries’ mission to make renewable energy affordable and accessible to everyone. Massachusetts

Flick Power was developed in California to help take advantage of new time-based electric rates and reduce carbon emissions from dirtier energy sources that are used during peak energy times. While other devices can automate select lighting and appliances, Flick helps you maximize the value of all of those devices, plus others that can be shifted to cleaner and cheaper times of the day. Flick is built with proven smart switch technology, with just the right amount of intelligence to help people within a building make better decisions about their energy use. California

Grid Fruit provides software that reduces energy and maintenance costs for food businesses. We use previously untapped data through AI software to bring energy efficiency and power grid incentives to refrigeration and HVAC. Pennsylvania

Neothermal Energy Storage offers homeowners the first integrated, supplemental electric thermal storage (ETS) system for boilers and furnaces that reduces fossil fuel use by up to 90%, lowering GHG emissions and monthly energy bills. Neothermal ETS enables the switch from oil (or other fossil fuels) to low-cost, off-peak electricity that capitalizes on the existing heat distribution infrastructure, fitting the needs of older, average-sized homes. When the existing fuel-burning system expires, customers can purchase an electric boiler or furnace (with or without a heat pump) and still enjoy the benefits of their connected Neothermal ETS. Founded in 2015, the core technology inside Neothermal ETS was developed by Dr. Louis Desgrosseilliers during his PhD studies on salt hydrate thermal storage at Dalhousie University in Nova Scotia, Canada. Neothermal Energy Storage is committed to building a clean energy future. Nova Scotia

“We have participated in a few similar programs, but so far, DeltaClimeVT facilitators have shown a whole new level of sophistication! Thank you so much for all the work you are putting in this program. We are truly enjoying it.”

Arshan SinghTechnical Business Developer, Enersion, Energy 2020 Participant

“We plan to use the $25,000 prize money to continue to develop our software product and serve clients in Vermont and greater New England. Onboard provides analytics software to uncover hidden energy, maintenance and comfort problems in commercial buildings. These problems are a significant reason commercial buildings emit more harmful emissions than transportation or industry. We’re thankful to Vermont, the program managers and sponsors of DeltaClimeVT, and the cohort of entrepreneurs that supported us this summer. We absolutely enjoyed our time in Burlington. We’ll be here frequently to serve clients and, if possible, establish a remote presence in this great city!”

Ryan HolyCEO, Onboard Data, Energy 2019 Winner
