In-current Kinetic and Head-based Hydropower

Systems for Off-grid Distributed Power


2

About 1/5 of the world’s population lives without power


3

By Any Measure, Energy is Key

country’s success

… and in many

areas of the world,

the quickest and

least expensive way

to get energy to

those that don’t

have it is to use

distributed power

systems.


4

Distributed Power Systems

• what they are: generation and/or storage located near the point of use

• they can include

• renewables

• fossil fuels,

• storage, and

• controls

• typ. 1 - 50 MW nameplate

• can be grid-connected or non-connected


5

Hybrid Systems - KIREIP, Tasmania

A common approach is a hybrid system. This

incorporates a mix of energy sources, often

including fossil fuels.

KIREIP (nameplate 3.3MW) is entirely self-

contained and allows King Island to be self-

reliant for its electricity needs.

Up to four subsystems may be called at any

given time: one fossil fuel, two renewable, and

one storage.

The logic control provides updates about

twice a second. Basic algorithm:

1. looks at system demand

2. strip off what can be had from the

renewables

3. top up the battery bank if surplus, and

4. run diesel gens if all else fails


6

Tidal Power in Hybrid Systems

• Tidal power is the only renewable that is 100

percent predictable.

• As such, it can stabilize power generation.

• It is every bit as predictable as diesel power,

and indeed costs in theory can pinned down

even tighter.

• As such, if there is velocity and flow sufficient

to produce power in a coastal DP system, it

can supplant diesel backups altogether.


7

Case Study: Indonesia

• ~1,000 inhabited islands

• only 300 have power

• tidal resource is complex but

looks good


8

A Quick Look Into LPS: In-Current MHK


9

• O&M regime – attack the #1 cost driver

• logistics ‒ use common marine equipment

• respect UKC

• placement in optimal part of water column

• hot-swappability ‒ no downtime; cf. solar

• minimize structure ‒ exploit tension

• allow for hyper-local variations in flow

What Informs our Thinking?


10

LPS Buoyant Modular Tethered Rack System

Per rack:

swept area 360m2

950kW output in 2.5m/s flow


11

Capital Efficiency: Installation

• use common marine equipment and

cargo logistics to greatly reduce ICC

• exploit power of the standardized

module

• pursue “server farm” topology

• respect UKC at all times but locate at

acceptable height in water column

LPS Recycled Container Temporary/Disaster Relief MHK Unit

Inexpensive, quickly deployed in-current

energy for

• forward areas

• disaster relief

• international patents pending

ROR HEAD-BASED HYDROPOWER


15

Inland Hydro: The Opportunity

Domestic new stream-

reach potential in the

USA is a $600 million/yr

industry. 12 million

MWh/yr can be

harvested annually. (source: U.S. Department of Energy)


16

Ultra Low Impact Hydropower

• 2013 FERC regs: streamlined permitting for small hydro sites• non-Federal canal <5MW in capacity: 60 day

• anything under 10MW in capacity: fast-tracked, est. <1 yr

• in conduits, up to 40MW in capacity: <1 yr

• minimal pondage; minimal environmental impact

• ROR takes advantage of natural flows and drops

• natural habitats and productive farmlands are not wiped out

• eligible for Class I RECs

• its Achilles heel is extreme variations in flow – so not suitable

as a baseload technique as is tidal


17

LPS Prefab Modular Hydropower

Net head from 10 to 60 feet

Cost reduction factors:

• shop (offsite) fabrication & assembly

• transport to site by ship/ rail/ truck

• removable power cassettes

• de minimus decommissioning costs @ end of service life


18

The LPS Approach

Penstock, powerhouse, spillway and

impoundment modules are all ISO

containers

fast installation, no cofferdam

needed


19

Modular Pumped Storage Hydro Using Water Towers

• Closed-loop modular PSH

• High frequency reversal

• Civil works built and permitted

• Pumps built and permitted
