From Austria: a carbon-free system consisting of a ready-to-use high-performance storage unit (DUALstore PLUS) and a thorium-based energy source currently under development (ADES)—container-based, modular, and suitable for use worldwide.
SMRX™: Clean baseload power for 8.5 cents/kWh. Lower energy costs for customers. Long-term, recurring cash flows for investors.
Powered by ADES—Accelerator-Driven Energy Source: Inherently safe due to the laws of physics and infinitely scalable thanks to its design.
The product
SMRX is our energy system consisting of two components: the DUALstore PLUS storage unit, which is already available, and the ADES energy source, which we are currently developing for mass production. In the finished system, SMRX can not only store energy but also generate it itself in a CO₂-free manner—as heat and as electricity.
Modular hybrid storage system (5–100 MWh) that combines thermal storage and battery power. Optimizes existing energy through bankable 20-year contracts.
Compact, thorium-based energy source (Accelerator-Driven Energy Source). It operates without a self-sustaining chain reaction, without weapons-grade material, and without long-lived nuclear waste—and turns storage into true self-generation. Currently in the prototype stage, completion in 2029—after which VDL will accelerate its development to production readiness.
The complete system: it stores and generates — high-temperature heat and electricity, container-based, deployable worldwide. The storage is available today; self-generation is added with ADES. Die 4 Arme des X sind:
What the X means
The “X” in SMRX stands for our approach—and for the technology behind it.
A new generation of energy production—not an evolution of traditional reactors.
The neutrons come from outside, from an accelerator—not from an internal critical chain reaction.
Inspired by medical technology: Neutrons are also generated using an accelerator in modern cancer treatment (a separate application, not part of Emerald Horizon). We use the same physical principle to generate clean energy.
We are from Austria, one of the most nuclear-skeptical countries in Europe. This skepticism is in our DNA—and that is precisely why we are developing an approach that is designed with safety as its top priority from the ground up.
We don’t operate like traditional nuclear SMRs: no self-sustaining chain reaction, no weapons-grade material, and no long-lived nuclear waste.
The reaction continues only as long as the accelerator keeps it going—if the accelerator is shut down, the reaction stops. Safety is intended to be ensured by the physics of the process itself, not by additional emergency systems.
Our team draws on expertise in particle physics from the world’s leading research institutions.
The individual components of the technology have been tested at renowned research institutions such as CERN, the IAEA, ORNL, MYRRHA, and PSI.
VDL Groep (approximately 15,000 employees) works with us to develop and manufacture products—which shortens the path to a market-ready product.
Seven years of development with minimal capital investment and regular audits (FFG) — proven research track record.
Small modular reactors and storage facilities are a key focus of EU energy policy—and we are developing solutions specifically within this funding framework.
The course has been set—the question is no longer “if,” but “who will deliver it.”
Members of the European Industry Alliance for Small Modular Reactors (SMR).
The EU has adopted a strategic action plan comprising ten targeted measures.
Goal: to have the first such reactors in operation in Europe by the early 2030s.
Off-grid baseload power right on site.
Heat, hydrogen & electricity for steel, aluminum, chemicals, cement, and food production.
Self-sufficient supply for vital facilities.
Deployable even without a grid connection.
Water treatment via desalination plants
Ship propulsion (direct)
EV charging stations (on-site power generation)
Aircraft fuel (fuel production at the airport, e.g. hydrogen)
Together with a cooperation partner, we are exploring whether the high-temperature heat from SMRX could in future also be used for hydrogen production — another field of application for CO₂-free energy.

Business Model
SMRX combines two income streams that are typically separate: steady, predictable income from storage today—and significant growth potential from energy generation tomorrow.
Today · DUALstore PLUS
Predictable, recurring revenue from leasing the storage units through long-term 20-year contracts. The solid, calculable foundation.
Tomorrow · ADES
The significantly larger earnings potential from CO₂-free energy generation — it grows with every additional installed module.
Energy as a Service
Our model is called Energy-as-a-Service: the customer does not buy an expensive plant but pays only for the energy delivered. This significantly lowers the barrier to entry — and helps us bring new technologies to market faster: first the storage, then step by step the complete SMRX system.
Decentralized, clean, and scalable energy systems foster not only the economy but also social advancement and stability in the regions concerned.
