New Off Grid Energy Harvesting Technologies


Critical business intelligence covering forecasts, players, case studies, opportunities and technology and market assessment

At first sight the technologies are the same between zero emission grid electricity production and off grid. Both are produced by photovoltaics and wind turbines in the main, with "blue energy" from water having a toe hold. That is misleading. It may need to be modular or part of a vehicle, even light enough to fly. Off grid photovoltaics is more likely to be in the form of structural electronics integrated into an aircraft wing or a house and have tolerance of shadowing and being at a poor angle to the sun. It may use more advanced chemistry such as GaAs. Quiet, low wind turbines near houses may best be H shape vertical Axis Wind Turbine H-VAWT, not the familiar horizontal axis monster. There may be little or no need for energy storage when the module makes clean water or hydrogen for example. Portability and replacing diesel gensets are challenges that on grid suppliers do not face. Off grid has a wider choice of new technologies coming along so it will become more and more different from the slower moving on grid industry. For instance, we believe that Airborne Wind Energy using tethered drones for lower cost, more continuous electricity from winds high above ground turbines is actually best suited to off grid use, partly because it is portable.

This session takes a close look at the successes, failures and issues with existing and future off grid technology. Learn the jargon and the options in detail and assess the IDTechEx take on future winners, losers and capabilities.

What you will learn

All the topics mentioned above will be covered by IDTechEx analyst Dr Peter Harrop in this dedicated forum on zero emission off grid electricity technology. The seminar will include:

  • Reasons for adopting off grid: not all about money and that affects technology.
  • Power levels, intermittency, reliability, safety and other key issues
  • Choices of energy harvesting now and in future, electrodynamic, photovoltaic, thermoelectric, piezoelectric, triboelectric, Dielectric Elastomer Generator DEG etc. Which are or will be transparent or conformal or otherwise useful in new ways. Efficiency trend by technology, important other parameters. Toxicity issues.
  • Wind turbines: why most small ones have no payback and what to do better in future. Maintenance, noise and other issues.
  • Assessment of Airborne Wind Energy AWE commercialising in 2018 and promised for the future. Will the winner be Kite, tethered drone, aerostat, rotating tether? Eight or spiral trajectory? Costs, problems, solutions. Comparison with wind turbines.
  • New forms of water power: rivers, waves, tide, other. Problems, potential, capabilities now and in future.
  • Use of two or more forms of energy harvesting in one system: reasons, examples, trends
  • Integration of off grid energy harvesting into multifunctional structures such as smart roads/ paths/ parking areas, barriers, into windows with controllable transmittance, other Building Integrated Photovoltaics BIPV etc.
  • Choices of off grid energy storage now and in future: batteries, supercapacitors, water, other
  • Off grid battery reduction/elimination by storing end product or by balancing several harvesting sources.
  • Choices of power electronics and control now and in future. Issues to tackle.

Please join Dr Harrop and the rest of the IDTechEx team on the 19-21 June 2018 at the Business and Technology Insight Forums Cambridge 2018 to learn more about LIBs and how your company can benefit from this booming industry.

For those attending.

Introduction

Compiled by Peter Harrop Chairman IDTechEx

  • 14:15 - 15:30

What drives the specification, important parameters

Compiled by Dr Peter Harrop, Chairman, IDTechEx

  • Reasons for adopting off grid: how technology choice is affected by primary objectives such as cost, level or predictability of cost, multiple uses or not, intermittency, installation time, size, weight, portability etc. Examples of very different specifications from advancing armies to aircraft, third world
  • Power levels, reliability, safety, cost and other key issues
  • Coping with intermittency: matching multiple sources to demand profile vs using energy storage or matching use to intermittency
  • 15:30 - 15:50
  • Networking break
  • 15:50 - 16:15

Energy harvesting technologies now and in future

Compiled by Dr Peter Harrop, Chairman, IDTechEx

  • Choices of energy harvesting now and in future, electrodynamic, photovoltaic, thermoelectric, piezoelectric, triboelectric, Dielectric Elastomer Generator DEG, electret, pyroelectric, magnetostrictive etc.
  • Efficiency trend by technology, important other parameters
  • Integration of different harvesting technologies: Pairing wind/ solar through to structural electronics with multiple harvesting modes
  • Example: How to make a zero emission, energy independent ship
  • 16:15 - 16:50

Wind and water power technologies

Compiled by Dr Peter Harrop, Chairman, IDTechEx

  • Wind turbines: why most small ones have no payback and what to do better in future. Maintenance, noise, efficiency, safety and other issues.
  • Assessment of Airborne Wind Energy AWE commercialising in 2018 and AWE promised for the future. Will the winning form of AWE be kite, tethered drone, aerostat, rotating tether? Figure of eight or spiral trajectory? Costs, altitude, legal constraints, problems such as lightning, birds, illumination, fragility. Solutions. Comparison with wind turbines. Why AWE is more suitable for off grid but most are chasing on grid applications.
