Q&A

One of the biggest challenges to the energy transition is finding the funds to fuel it. Tyler Lancaster, partner at Energize Capital, is playing a role in that.

Energize Capital, based in Chicago, is focused on disruptive software technology key to decarbonization. One of the firm's portfolio companies is Amperon, which raised $20 million last fall.

In an interview with EnergyCapital, Lancaster shares what he's focused on and why Amperon caught Energize Capital's attention.

EnergyCapital: Energize Capital has been investing in climate tech for the better part of a decade now. What types of companies are you looking for and how are these companies’ technologies affecting the greater energy transition?

Tyler Lancaster: We partner with best-in-class innovators to accelerate the sustainability transition. This means identifying climate technology companies at various stages of maturity — from early commercialization to approaching the public markets — that we can help scale and realize their full potential. We invest in software-first climate technology businesses, with a focus on asset-light digital solutions that can help scale sustainable innovation and enable the new energy economy. Our portfolio currently drives software applications across renewable energy, industrial operations, electrification & mobility, infrastructure resilience, and decarbonization. We primarily focus on proven, commercially available and economically viable energy transition solutions (solar, wind, batteries, heat pumps, etc.). These solutions suffer from challenges related to efficient deployment or operations, where enabling digital platforms can play a key role in optimizing costs.

EC: Amperon is one of Energize Capital's portfolio companies. What made the company a great investment opportunity for Energize Capital?

TL: Accelerating the energy transition will require critical forecasting tools like what Amperon provides. This is underscored by the escalating impact of extreme weather events, increasing penetration of variable energy resources, like wind and solar, on the supply side, and surging demand growth driven by flexible loads and rapid electrification. We believe the need for Amperon’s platform will only continue to grow, and their increased raise from Series A to Series B showed they are scaling smartly. We’ve also known Sean Kelly, Abe Stanway, and the entire Amperon team for a long time, and building strong relationships with founders is how we like to do business. Amperon has built a blue-chip customer base in the energy sector in a very capital efficient manner, which is more important than ever for startups operating in the current equity market environment.

EC: One of the energy transition’s biggest problems is sourcing and storing reliable and affordable energy. What have you observed are the biggest problems with Texas’ electricity grid and what types of new tech can help improve these issues?

TL: Today’s electricity grid and the demands we’re putting on it look very different than they ever have. Major changes in climate and extreme weather show how perilous and unreliable the power grids in this country are, particularly in regions like Texas that don’t have the right infrastructure to shield grids from unusual temperatures — just look at the damage done by 2021’s historic Winter Storm Uri. And consumer demand for electricity is increasing as electrification accelerates globally. The makeup of the grid itself is shifting from centralized power plants to distributed clean energy assets like solar arrays and wind turbines, which brings issues of intermittent electricity production and no traditional way to forecast that.

Tech solutions like Amperon are the only way to navigate the nuances of the energy transition. With global net-zero goals and impending Scope II accounting, Amperon’s expertise in granular data management further enables companies to build accurate, dynamic forecasting models with smart meter data and get more visibility into anticipated market shifts so they can optimize their energy use — all of which helps to create a more resilient and reliable power grid.

EC: You are also on the board of the company, which recently announced a collaboration with Microsoft’s tech. What doors does this open for Amperon?

TL: Partnering with Microsoft and offering its energy demand forecasting solution on the Azure platform enables Amperon to better serve more companies that are navigating the energy transition and a rapidly evolving grid. Many power sector companies are also undergoing cloud migrations with Microsoft Azure having high market share. This partnership will specifically accelerate Amperon’s reach with utility customers, who typically have slower sales cycles but can greatly benefit from improved accuracy in energy demand forecasting and adoption of AI technologies.

EC: As a non-Texas investor, how do you see Houston and Texas-based companies’ investability? Has it changed over the years?

TL: While most tech startups are concentrated on the coasts and in Europe, we see Texas emerging as a hub for energy and climate focused startups due to its vicinity to energy giants, which represent potential customers. Texas leads the country in renewable energy production and sits at the forefront of the transition. Energy companies based in this region are relying on technology innovation and software tools to modernize operations and meet the evolving demands of their customers.

Houston startup wins Space Force contract to advance quantum energy generator

quantum contract

Houston-based quantum energy technology startup Casimir Inc. has been awarded an STTR Phase I contract from the U.S. Space Force's SpaceWERX to support the development of the company's solid-state generator for potential use by the Department of the Air Force.

SpaceWERX is the innovation arm of the U.S. Space Force and a division within AFWERX, the incubator and innovation arm of the United States Department of the Air Force. The Air Force Research Laboratory and SpaceWERX, along with many other government agencies, help support innovation through the Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) grants and contracts.

As part of the new contract, Casimir will work to refine a fully independent generator. Casimir’s solid-state power technology could support national security missions by providing reliable power even in difficult-to-service environments.

In May, Casimir emerged from stealth, netting a $12 million seed round to commercialize its quantum energy chip. The semiconductor chips can generate power from quantum vacuum fields without the need for batteries or charging. The company aims to include the chips in large-scale energy systems that can power homes, commercial infrastructure and electric vehicles.

“This STTR funds some analysis work to address our proposed scaling approach of making our chips multi-layer to increase aggregate power,” Harold “Sonny” White, founder and CEO of Casimir, tells Energy Capital.

White adds that the company will work with Texas A&M to develop chip planarization techniques to support Casimir’s plans to scale. Additionally, White says the company is working with the U.S. Space Force to explore more applications for its technology.

“Casimir’s technology brings a new capability to the market in the form of our persistent power chips,” White adds. “This approach will be relevant to ultra-low-power electronics, and with the scaling approach we are developing, connected with the STTR work, will eventually be relevant to consumer electronics and beyond.”

Casimir has previously reported that it plans to commercialize its first-generation MicroSparc chip by 2028. The chips are expected to power devices for years without the need for replacements.

The total funding for this project has not yet been disclosed.

Sage Geosystems brings South Texas geothermal plant online

powering up

Houston-based Sage Geosystems, a provider of geothermal power, has begun full operations at its South Texas facility for the San Miguel Electric Cooperative.

Sage says the plant was recently “placed in service,” according to a news release. This means it’s fully built and tested, and ready to generate and supply electricity to the grid.

Since selling its first electricity in Q2 of this year, the facility has been operating for more than four months to evaluate aspects like efficiency and water management. Sage relied on its GeoTwin modeling tool to carry out some of the testing.

The testing demonstrates Sage’s proprietary approach to geothermal power “overcomes one of the industry’s most persistent challenges, high water losses in engineered reservoirs, while delivering the consistent performance required to scale next-generation geothermal,” co-founder and CEO Cindy Taff said in the release.

Sage says the South Texas facility will serve as a model for future projects, including one in Nevada. The Nevada facility will use Sage’s proprietary technology to extract geothermal heat from hot dry rock, creating a reliable, affordable source of carbon-free power.

During the testing period, water losses amounted to less than 10 percent. This low rate indicates most water remains in the system, enabling Sage to capture more usable energy, boost power production and improve the project’s finances, the company says.

“Commercial geothermal isn’t just about creating a reservoir. It’s about creating one whose performance can be engineered, predicted, and consistent,” Lev Ring, the company’s co-founder, president and chief technology officer, said in the release.

Since being founded in 2020, Sage has raised $159 million in outside funding. This includes a more than $97 million Series B round co-led by Ormat Technologies and Carbon Direct Capital.

Two years ago, Sage announced a deal with Meta Platforms, the parent company of Facebook and Instagram, to supply up to 150 megawatts of geothermal power to Meta data centers.
