Water, power, stored heat and carbon-negative fuel. From one modular platform.

Problem

Three problems, one platform

BEG is designed against three structural challenges that today's infrastructure handles separately, and at high cost.

• Water scarcity

  Conventional reverse-osmosis desalination is energy-intensive, grid-dependent, and unable to follow demand changes. Coastal regions like Malta depend on it, and pay for it twice: once in electricity, once in environmental damage.

• Energy transition economics

  Solar PV produces electricity only. Heat is wasted, water is ignored, storage is bolted on after the fact. Most renewable installations achieve roughly 20% solar-to-useful efficiency. Useful output per square metre stays low.

• The toxic brine problem

  Existing desalination plants discharge approximately 142 million tonnes of concentrated brine into the sea every year, damaging marine ecosystems near every coastal city that drinks from a desalter. Regulation worldwide is moving toward Zero Liquid Discharge.

What BEG is

A modular platform, not a single machine

BEG is a standardised system of interchangeable modules connected through six shared buses: Thermal, Steam, Water, DC, Brine and Control. Any energy source connects to the same downstream infrastructure. Any output module connects to the same upstream supply.

This means three things in practice:

• No lock-in to any single energy source. Solar, waste heat, pressure recovery, wind, wave, geothermal and biomass all connect through the same interfaces.
• No lock-in to any single geography. Sun-rich coastlines, industrial sites, pipeline installations and geothermal zones all run on the same core architecture.
• No stranded assets. When conditions change, operators swap modules, not infrastructure.

This bus-based modularity is rare in infrastructure systems and is BEG's primary structural advantage. It is also what makes the technology shippable as a product family rather than a bespoke build for every site.

Performance

Engineered for combined output, not single-product efficiency

BEG measures itself on combined heat, power and water (CHP-W), not electricity alone. Against that benchmark, the integrated platform meaningfully outperforms separate single-purpose systems.

Reference figures derived from the BEG Configurator V3 (Malta solar pathway, industrial scale). Core technologies are validated in peer-reviewed research from MIT, Fraunhofer, PNAS and Nature Energy. The integrated control loop and platform-level performance are validated through the Malta pilot programme.

Outputs

Six outputs from one thermal loop

• Clean water

  Potable, agricultural or industrial grade. From seawater, brackish water or atmospheric moisture, depending on configuration. Output passes through a controlled remineralisation step to meet WHO drinking-water standards where required.

• Electricity

  Generated through scroll, ORC, steam-turbine or pressure-let-down conversion. Distributed through a stabilised DC bus that abstracts away the underlying generator type.

• Stored thermal energy

  PCM-based heat storage enables continuous operation through diurnal cycles and variable input conditions. The thermal store decouples generation from consumption.

• Carbon-negative liquid fuel

  Formate (around €1.50/kg at 100 t/yr) and methanol, synthesised from captured CO₂ and concentrated brine through the optional BFA (Brine Valorisation) module.

• Recovered minerals

  Lithium, magnesium, sodium chloride and gypsum extracted from concentrated brine alongside fuel synthesis. Zero liquid discharge by design.

• Carbon credits

  Approximately 1.1 tonnes of net CO₂ removal per tonne of fuel produced. The full BFA loop converts a regulated waste stream into a credit-eligible output.

Deployments

Seven deployment profiles, one architecture

The same hardware family runs in radically different environments. Each profile below corresponds to a live preset in the configurator, where the full module composition and runtime numbers can be inspected.

• Malta Solar Pilot

  Fresnel concentrators drive the thermal loop. Turbine waste heat feeds MED desalination. Optional AWG and BFA modules. The reference deployment.

• Factory Waste-Heat

  Existing process heat from a factory replaces the solar input. The brine bus is repurposed for flue-gas or direct-air CO₂ capture. Output is power, recovered water and captured CO₂.

  Open in configurator

• Hybrid Solar + Wind

  Two complementary energy sources feed the same thermal and DC buses for higher capacity factor and continuous operation.

  Open in configurator

• Power Station

  Multiple solar fields plus waste-heat input, scaled to roughly 1,000 m² module area. Designed for utility-grade output with full BFA integration.

  Open in configurator

• Desert Oasis

  Pure atmospheric water generation in the absence of seawater access. Solar-driven, with an optional air conditioning module for the host site.

  Open in configurator

• Pipeline Pressure-Recovery

  A pressure-let-down stage replaces the heat engine, converting otherwise-wasted pressure differentials in gas pipelines or oil-rig infrastructure into electricity.

  Open in configurator

• Maritime Port

  Wave and wind drive the thermal and DC buses. Suited to ports and offshore platforms where seawater access and renewable resources are co-located.

Scale

From 10 m² to 1,000 m². Same platform

BEG scales by composition rather than redesign. The smallest residential unit and the largest power-station deployment use the same module families and the same six-bus architecture. Outputs scale roughly linearly with footprint.

• Residential
  ~10 m²
  • ~6 kWh electricity / day
  • ~400 L water / day

  Roof or terrace mounted. Household electricity, hot water and drinking-water supplement.

• Industrial
  ~100 m²
  • ~75 kWh electricity / day
  • ~4,000 L water / day (including AWG bonus)
  • ~40 kWh thermal storage

  Hospitals, hotels, data centres, agriculture and light industry.

• Power-station class
  ~1,000 m²
  • ~750 kWh electricity / day
  • ~40,000 L water / day

  Utility-scale water and power with full BFA integration.

Malta pilot

Malta, the first deployment

Malta is the proving ground for BEG, and an unusually well-matched one.

Year-round solar resource validates the solar reference pathway. The island depends on reverse-osmosis desalination, which today discharges concentrated brine directly into the Mediterranean and damages marine ecosystems near the coast. The market is small enough to be visible, and sensitive enough to make a clean alternative immediately relevant.

The pilot integrates with Malta's existing energy and water systems rather than replacing them. The aim in the first deployment phase is to ease peak load on the grid, add a green-supply component across electricity, water, stored heat and captured CO₂, and provide resilience in locations where a single central failure would otherwise leave residents exposed.

Active collaboration is in place with the University of Malta, MCAST, and Maltese government-led science and development institutes. The Cirkewwa coastal site is the preferred location, combining sea access for desalination testing, available surface area for staged build-out, and proximity to existing road infrastructure.
