IMAGINE…a solar power solution

Ø That takes the best characteristics of PV and CSP Ø Discards the worst characteristics of PV and CSP AND Ø adds additional benefits

Takes the best of PV…………….

  • Low cost
  • Distributed to utility scale
  • Low O&M/OPEX

and the worst of CSP:

  • Cost
  • Complexity
  • Long project cycles
  • Environmental challenges
  • Siting constraints

Discards the worst of PV……..

  • Unreliable, sunshine-only operation
  • Non-dispatchability
  • Grid instability

plus the best of CSP:

  • 24 hour operation
  • Dispatchability

And adds additional benefits

  • Battery-like response to grid voltage/frequency fluctuations
  • Super flexible operation
  • Elimination of expense of emergency backup power plants
  • No cost, instantly-responsive spinning reserves
  • Wholesale market arbitrage

  • 1. Maximize mass production of all components, like PV and wind
  • 2. Minimize on-site construction time and cost, like PV and wind
  • 3. Standardize a modular product, like wind machines
  • 4. Slash O&M with few moving parts, no risky materials, simple
  • peration

Design Approach

Focus on lowest cost, THE driver to market acceptance

Competitive with PV+batteries, will be competitive with coal

  • 1. Mass-produced 2. quickly assembled 3. standardized, identical

modules with 4. few moving parts, no exotic materials, no water/steam (low O&M)

The Solution: 247Solar Plants™

  • Firmly dispatchable every hour of the year
  • Low risk, mostly proven, locally made equipment
  • Simple, remote operation, low maintenance
  • Battery-speed grid stabilization
  • Super flexible operation

Distributed to utility scale

Operates 24/7 using very low cost thermal storage with fuel backup

üNext generation CSP eliminates all major shortcoming of conventional CSP and PV üMIT originated üUS Department of Energy funded (USD5 million) üCompetitive with PV with batteries but also 24/7 reliability; adds to grid resilience,

flexibility; battery-like demand and voltage fluctuation response; spinning reserves

üStand alone (villages, mines, etc) or utility scale üPerfectly matches emerging markets need for 24/7 clean power üLocally made components for local use/jobs and for export

Summary: 247Solar Plant™

Lowest cost 24/7 solar electricity
