Tapping into the rapidly evolving opportunity of integrating renewable energy resources with the power grid, Axle Energy, based in the UK, swiftly embraced the initiative to speed up the grid’s decarbonization since its establishment in the early months of last year.
The war in Ukraine, which led to a worldwide surge in energy costs, along with an increasing shift towards renewable energy use, spurred CEO and co-founder Karl Bach (pictured above left alongside co-founder and CTO Archy de Berker) to prioritize the development of software aiding the energy transition. Before launching their venture, the duo gained experience across the UK and overseas, working with energy suppliers and flexibility service providers, ultimately steering their career paths towards entrepreneurship.
Axle Energy operates as a B2B enterprise focusing on backend infrastructure. Its core mission is to link flexible assets like electric vehicles, home batteries, and heat pumps with energy markets previously inaccessible to everyday consumers. This approach lets users earn rewards for contributing to the stability of the grid amidst the unpredictability of wind and solar power production. For instance, households can benefit financially by adjusting when they charge their electric vehicle or by opting to use a home battery system instead.
The intermittent nature of renewable energy sources adds to the grid’s supply instability, a gap usually bridged by relying on electricity generated from fossil fuels which receive financial rebates for their role. However, Axle’s innovative software presents a cleaner alternative to help balance energy demand and supply without resorting to fossil fuels.
Describing Axle as an entity focused on energy flexibility, Bach shared in a Zoom conversation, “Our work involves connecting distributed resources like electric vehicles and batteries to the energy market to facilitate decarbonization of the grid. This requires moving beyond fossil fuels and harnessing renewable energy, even though the availability of sun and wind can be inconsistent.”
The inconsistency of renewable energy has been a longstanding critique by the fossil fuel sector. The critique often questions the logic behind enlarging wind and solar infrastructure if there remains a need for conventional power plants for backup. The solution, Bach suggests, lies in smarter energy management.
As the electrification of various industries progresses, there emerges a potential to establish a demand control framework capable of dynamically reshaping energy consumption through precise regulation of connected devices. This is what Axle refers to by labeling itself an “energy flexibility company”.
Historically, it was only the large commercial and industrial consumers who were compensated for adjusting their energy demands in times of grid stress. Axle’s system enables owners of smaller assets, such as electric vehicles, to collectively reduce their power consumption in response to demand, thereby earning financial rewards transferred from the grid operator through Axle’s partnership with device manufacturers.
“The grid, as it stands, operates in a manual, hierarchical mode, requiring human intervention for adjustments. This model is becoming obsolete with the advent of distributed generation and consumption happening in real-time,” Bach explained to TechCrunch. “The future grid, we believe, will have to adopt a distributed and dynamically operated structure, reacting to real-time price signals at every node. This significant transformation, unseen in the last century within electricity grids, is what our software infrastructure aims to facilitate.”
He further asserts confidence in completely eliminating fossil fuels from grid balancing by 2030, anticipating the UK grid’s need for approximately 40 gigawatts of flexibility by decade’s end, with all of it potentially deriving from carbon-neutral sources.
Bach reassures that for device users, participating poses no disadvantages. Beyond earning rewards for aiding in grid balance, they maintain ultimate control, capable of bypassing optimization settings for immediate needs, like EV charging. “We’re not usurping control from them,” he stresses. “We offer an opportunity for monetary gain through system optimization, yet the power of decision always remains with the user.”
We believe it is possible — and we will be able — to kick out fossil fuels in grid balancing by 2030.

Since initiating its platform a year ago, Axle reports connecting over 15,000 flexible assets to energy markets, summing up to more than 85 MW of capacity and indirectly reaching over 500,000 UK households or exceeding 6 million globally. Its collaboration extends to notable asset manufacturers such as SolarEdge, myenergi, Pod Point, and GivEnergy, though the exact number of its clientele remains undisclosed.
Device manufacturers see the value in offering their users incentives to engage in grid stabilization, bolstering customer allegiance. As Bach notes, the rewards mechanism is managed through Axle’s partners, though direct payments for contributions are standard.
By year’s end, Bach anticipates enabling savings of [up to £400 per EV or home battery annually] for users through partner channels by tapping into a wider array of UK energy markets than currently accessed.
With ambitions to encompass all UK energy markets swiftly, Axle aims to enlarge its engineering team, fueled by a $9 million seed funding round intended for this expansion and to penetrate additional European markets. Though specific targets are yet to be decided, Bach expressed enthusiasm for immediate scaling to address the pressing demands of climate challenges.
Bach highlights the speedy progression of their venture, noting, “Our existing clients … have distributed over 6 million of these flexible devices globally. With the growth rates of EVs and home batteries, we’re not only enhancing the consumer business case but also accelerating market growth.”
When considering Axle’s approach in the U.S. energy sector, Bach admits, “Yes, but not immediately. We have set our sights on the U.S., likely extending beyond the next year. The complexity of the U.S. regulatory landscape does pose challenges; however, innovative programs in places like Texas with Tesla hint at the model’s potential expansiveness, especially alongside increasing rates of EV adoption.”
Regarding competition, Bach views Axle as pioneering an untouched space, albeit acknowledging the growing focus on energy transition startups and some indirect competition, notably from new energy suppliers like UK’s Octopus Energy. Yet, Axle’s B2B strategy sets it apart from directly competing consumer-facing entities and traditional companies venturing into small-scale asset balancing.
The $9 million seed investment was spearheaded by Accel, alongside contributions from Eka Ventures and Picus Capital, complemented by notable angel investors, symbolizing confidence in Axle’s future trajectory.
With its total funding since February 2023 hitting around $10M (£8M), Bach is optimistic about overcoming the universal grid decarbonization challenge, supported by collaborative efforts worldwide, stepping into an uncharted future with a collective vision.
