Ice house in Boxborough, Ice storage in Iran MA Concept:

• Transfer heat to/from water during hot or cold weather • Inject the water into a borehole array (BTES) or an aquifer (ATES) for seasonal thermal energy storage

• Recover stored hot or cold water and use it in any application where it can be transferred through a heat exchange loop – HVAC, deicing, preheating, and other applications

Components of a Conventional Ground-Source Heat Pump System

Earth Couple / Interior HVAC Heat Pump Ground Heat Exchanger / Ground Loop

Ideally, the ground exchange loop increases the efficiency of the heat pump Underground Thermal Energy Storage (UTES)

Aquifer Thermal Energy Storage Borehole Thermal Energy Storage ATES BTES

• Open Loop (hydraulically balanced) • Closed loop

• Seasonal flow reversal (well-to-well) • Seasonal flow reversal (GHX)

• Groundwater storage medium • Soil/rock storage medium

• Economic efficiencies of scale • Cost varies with thermal capacity

Borehole Thermal Energy Storage (BTES)

Summer Winter

• Closed loop • Radial array configuration – may use multiple arrays • Seasonal reversal of flow within the loop • Small footprint on storage site

Aquifer Thermal Energy Storage (ATES)

Summer Winter

• Seasonal thermal energy storage enabled by: • High heat capacity of (ground)water • Dynamics of fluid flow in porous media • Low ΔT, low advection • Hydraulic modeling and management of aquifer • Open loop with separate warm and cold stores • Seasonal reversal of warm and cold withdrawal / injection • Hydraulically balanced • Thermally balanced Possible Matches

A complete project includes: • Identifying the ideal location, physically and on the grid • Permitting/consenting • Electrical interconnection • Storage technology(ies) appropriate for the situation (MW, MWh, ramp rate) • Electrical balance of plant – substation, interconnection facilities, , cabling • Control and management systems • SCADA (Supervisory Control and Data Acquisition) for the storage project • Interface with grid operator and others for dispatching (absorbing vs regenerating electricity) on several timelines • Health and safety • Financing • Contracting for construction, planning for operations & maintenance • Risk management and insurance Privileged and Confidential US vs Europe Opportunities

US market for balancing renewables • Modest penetration of wind and solar in most parts of the US • Very low prices (due to recent “fracking” boom) make gas-fired backup the economical choice

• No cost or government mandate for CO2 • Pockets of opportunity with high renewables penetration (e.g. Bonneville Power Administration area – 40% wind) or small grids (e.g. Hawaii) • May be opportunities in PJM due to decommissioning and gas generating as baseload

European market for balancing renewables • Very large penetration of wind and solar in several countries (particularly UK, Germany). This will be continent-wide in the near future • Much higher natural gas prices than in US plus concerns about security of supply (much gas comes from Russia) • European Union mandate for “decarbonisation” makes fossil-fuel backup untenable • Interesting grant programs in the UK, other countries and European Commission

Privileged and Confidential Customer-Oriented Business Development

Several customer segments: • Electric grid operators • Transmission System Operators (TSOs) • Distribution System Operators (DSOs) • Renewable generators – wind, solar, offshore wind • Large electric load customers with variable demand and need for backup power • Energy traders who see value in arbitrage and ancillary service markets • Competitive wholesale electricity suppliers

Any storage project has four parameters. Force 3 Energy can customize a solution depending on customer needs Location on the transmission or distribution grid Power generation capability, in megawatts Energy storage capacity, in megawatt-hours Response time, or ramp rate
