The challenge

To be part of a competitively-selected cohort of startup and/or seed stage ventures who offer products or services, including smart home and building technologies, aimed at reducing fossil fuel use and greenhouse gas emissions in buildings, enable better integration of distributed resources and smart building technologies, increase resiliency and/or support demand management strategies that avoid peak time energy usage.

The goal for the DeltaClimeVT Energy2020 program is to help move us toward a zero-carbon future through better integration of distributed resources and smart building technologies and to help Vermont’s utilities harden the distribution network against outages.

We were particularly interested in technologies that have wide potential applicability and enable low and moderate-income populations and multi-family building residents to participate in the low-carbon economy.

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

  • Innovative heating systems, such as advanced wood heat, geothermal heat pumps, advanced air to water heat pump systems or heat pump technology with integrated storage or demand response controls;
  • Building controls that align with utility demand response signals;
  • New weatherization materials or building construction materials that have lower embodied carbon footprints and help reduce energy use;
  • Smart thermostats, EV charging supply equipment and other devices to include storage that could align with utility demand response signals;
  • Fuel cell technologies;
  • Innovative solutions to bring reliable connectivity (ex. broadband) to rural areas to enable behind the meter technologies;
  • Innovative financing models for technologies and services (e.g. innovative loans, on-bill financing, heating as a service)
  • Any other technology or service that reduces energy use and greenhouse gas emissions in buildings and/or supports demand management in buildings.

The Results

After four months of intense focus, camaraderie and virtual learning, we are pleased to announce the Energy 2020 winners as selected by their peers: Pecos Wind Power ($25,000 non-equity award), Medley Thermal ($15,000 non-equity award), and Wex Energy ($10,000 non-equity award).

The companies

Camberline Technologies enables a time of use electricity pricing for households and small businesses, whereas such pricing is typically only offered to industrial users. Thus, they are a platform for financial incentives that encourage energy efficiency and emerging technologies such as EVs and energy storage. Their solution reduces capital costs and deployment time, empowers consumers with choice, while creating a market signal for their investment in sustainable, green, resilient, low carbon technologies. They provide a hardware driven metering and data management service that plugs seamlessly into existing utility infrastructure to provide data-as-a-service to electricity suppliers so that they can bill for time-based rates. Their service provides revenue-grade interval meter data to electricity suppliers without waiting for the local utility to install smart meters. Their software delivers billing-ready data to supplier or utility billing systems, using existing data exchange interfaces and standards. Electricity suppliers can offer time-based rates because Camberline can deliver revenue-grade data for revenue collection. Massachusetts

Enersion has developed an innovative cooling technology that uses low grade waste heat instead of electricity to produce cooling, resulting in over 70% less electricity consumption compared to regular chillers. In addition, Enersion’s technology uses plain water instead of the synthetic refrigerants that are used in compressor-based chillers that contribute to global warming. The chiller can utilize any low-grade waste heat including solar heat, industrial waste heat or rejected heat of a data center. Their product is a chiller that provides cooling (in the form of cold water) using low grade heat (~ 70 deg C) based on the phenomenon of aDsorption. The chiller uses water as a refrigerant as opposed to synthetic refrigerants (CFCs, HCFCs and HFCs) that contribute to global warming. Enersion’s chiller uses nano-porous materials that have high surface area. This material has the property to adsorb water and allow massive evaporation under vacuum pressure, resulting in powerful cooling.  Toronto, Canada

InfiSense is the easiest way for businesses to integrate low cost, long-life, real-time wireless sensing data into their workflows. InfiSense provides cloud software and an open API to connect, configure, contextualize and unify data from disparate IoT sensors for immediate use in analytics and applications. The company primarily serves businesses that provide data-driven services and software to building owners/operators to drive out costs, increase efficiency and improve sustainability. InfiSense enables reliable, wireless monitoring deep indoors and outdoors by leveraging state-of-the-art Long Range Wide Area Network (LoRaWAN) technology. Businesses that struggle to get data from hard-to-reach places can now sense any environment for any use case with wireless sensors that run for 3-7+ years and communicate for miles to a single gateway, where the data is then sent to InfSense’s cloud software. InfiSense works with any qualified LoRa sensor on any LoRaWAN network and delivers the data via open API, freeing its customers to use any business intelligence tool, software platform or application.

M2 Thermal Solutions has developed a new thermodynamic mechanism that is used for residential air-conditioning. Nearly all space cooling and refrigeration technologies deployed today use the vapor-compression cycle. These vapor-compression systems use refrigerants that are environmentally damaging, and they use large amounts of electricity to enact residential cooling. Their technology does not use any type of high energy consumption compressor, does not utilize any type of refrigerant, and consumes 70% less electricity than existing units while meeting the same thermal loads. They are now fabricating and validating their first-of-kind prototype. Massachusetts

Medley Thermal develops and dispatches hybrid electric boiler projects. Their solution—dynamic electrification—switches steam generation from fossil fuels to electricity at times when electricity is cheap and clean. By selectively using electricity to offset higher cost and more emissions intensive fuels, our customers can save money and reduce emissions. A dynamically electrified system adds an electric boiler in parallel to the existing boiler system and uses intelligent dispatching software to manage fuel switching between the boilers without disruption to the supply of steam. The dynamically electrified system essentially acts as a smart hybrid. Their software dispatches systems based on electricity market prices, the real-time carbon intensity of the grid, energy tariffs & fuel contracts, and technical constraints to optimally dispatch the boilers. Massachusetts

Pecos Wind Power is developing a low cost, 85kW distributed wind turbine to compete on cost with distributed solar and utility-provided electricity. In the United States alone, there is sufficient distributed wind resource to meet 100% of the nation’s electricity demand. This resource, however, has been largely untapped because the cost of distributed wind turbines has failed to keep pace with the declining costs of other electricity sources like distributed solar and utility-scale wind. Their team consists of 4 design engineers from some of the top utility-scale wind turbine manufacturers: Vestas, Siemens Wind Power, and Clipper. They have completed the preliminary design of their turbine and expect a cost of energy 40% less than the best-selling distributed wind turbine in its class thanks to an innovative tilt-up tower system and a rotor optimized for low wind speed power production. Massachusetts

Switched Source provides power electronics equipment that automates balancing of the distribution grid allowing for more renewable generation hosting capabilities, better power quality, enhanced reliability/resiliency, and reduced operational expenditures. They are introducing the next generation of power system automation technology for large commercial and industrial (C&I) customers and electric utilities. Their equipment addresses utilities’ top concerns and has already been accepted for “rate recovery” by a public utility commission. The equipment pays for itself with traditional value streams of increased reliability, resiliency and efficiency, while “future-proofing” the grid for the rapid onset of distributed generation and electric vehicles. New York

ThermoAI uses patent pending proprietary machine learning algorithms to optimize the total processes of industrial combustion. Their value proposition is to use artificial intelligence to optimize and automate combustion, saving millions in fuel and lowering emissions. Their systems constantly monitor all combustion factors and are constantly optimizing levels to keep a close to perfect combustion — saving fuel, increasing energy output, increasing lifetime value of expensive parts, and lowering emissions. They have been able to increase combustion level efficiency 10-15% at power plants. New York

WexEnergy delivers energy efficient solutions for buildings and homes one window, one building, one city at a time. WindowSkin’s® proven, cost-effective technology increases property values by increasing property net operating income and reducing GHG emissions. Windowskin Classic, their first product on the market, takes single-pane windows to double-pane energy efficiency and double-pane windows to triple-pane energy efficiency for approximately 10% of window replacement cost. WindowSkins reduce HVAC energy consumption by reducing thermal loss at the window. This reduction in fossil fuel consumption decreases the property’s carbon footprint. WindowSkin is a featherweight, easy to mount, long lasting window retrofit that retains window transparency and operability. New York
