Rondo Energy’s Financing Illustrates a Novel Path Through the ‘Valley of Death’ for Climate Startups

In the realm of startup investments, climate technology rivals AI in attracting substantial venture capital funds, necessitating significant financial injections, often surpassing traditional venture capabilities, to achieve impactful market presence.

A fresh strategy for addressing funding hurdles is showcased in Rondo Energy’s recent initiative, which specializes in thermal energy storage: philanthropic contributions.

For climate tech enterprises like Rondo, particularly those focused on developing tangible products, advancing from concept or initial testing to commercial sales presents a significant barrier. This challenge is sometimes referred to as the “commercial valley of death” or the “first-of-a-kind” dilemma.

At this juncture, securing investment is particularly challenging due to the absence of a proven risk-reward model for investors.

Venture capitalists are often reluctant to engage at this critical phase as much of the technical uncertainty has been mitigated, which could imply lower potential returns. Meanwhile, infrastructure financiers shy away from backing such pioneering projects due to perceived riskiness, creating a serious predicament repeatedly discussed among climate tech financiers—highlighted by Exantia’s creation of themed merchandise around the issue.

Even the team at Bill Gates’s Breakthrough Energy, with its venture capital and growth-stage Catalyst platform, recognizes the challenge. Catalyst recently disclosed an agreement aimed at providing a model for bridging this funding gap.

In collaboration with the European Investment Bank, Catalyst unveiled a plan on Wednesday to allocate €75 million in project finance for deploying three of Rondo’s thermal energy storage systems. These systems are capable of retaining intense heat up to 18 hours, with the objective to demonstrate the startup’s capacity to replace fossil fuel usage across numerous industries. However, it’s the structure of this financial arrangement that could set a precedent for future deals.

Notably, while the European Investment Bank’s contribution is a loan, Catalyst is providing a grant. Grants are not uncommon in the early stages of climate tech, targeting yet-to-be validated core scientific or technological advances. Conversely, Catalyst’s grant aims to address a more mature challenge: customer adoption and integration.

“This represents a full-scale commercial application and roll-out, without the requirement for additional tests. It is purely its novelty that stands out,” explained Mario Fernandez, lead of Breakthrough Energy’s Catalyst program, in a discussion with TechCrunch.

The trio of clients engaging in this project—a chemical production site, a cogeneration plant, and a food and beverage manufacturing facility—were prepared to trial new technology but were hesitant about incurring its costs. Infrastructure investors were also not ready to provide financial support.

“In the infrastructure investment realm, a comprehensive checklist needs to be satisfied before committing funds,” Fernandez noted. “An integral part of our mission is to navigate these requirements, facilitating investment in such innovative projects.”

Catalyst anticipates that the successful implementation of Rondo’s systems will convince infrastructure investors of the viability and manageability of such projects, thereby not just facilitating future financing for Rondo but also charting a course for other investors and startups exploring similar innovative technologies.

“While our funds aren’t limitless to mitigate the risks across all technology paths, our broader aim is to propel the entire ecosystem forward,” concluded Fernandez.
