THE NEED

THE MARKET

RE curtailment is a growing occurrence

Storage is required not just for hours but

days/weeks/months

The traditional route of storing energy has limitations of

capacity

GWhrs (weeks/months) of energy storage is only

achievable with hydrogen

Europe leading the way so far…..


CURTAILMENT = LOST ENERGY & MONEY

WHY POWER-TO-GAS?

POWER-TO-GAS RATIONALE

Electricity cannot be stored easily | Hydrogen can be stored easily in the gas grid


Gas Grid = a HUGE existing asset!!

P2G PLANT & VISITOR CENTRE




Three year project

Operational since December

NOT a technology demonstration– utility already convinced of capability of the technology

Designed to

• Educate regulators – who will be paying for demand management – that the system is a responsive load and can meet requirements

• Help develop the business model: payment structure that supports investment, allows calculation of ROI.

Energy Storage

THUGA DETAILS




Ideal marketplace

Cheap power – e.g. Curtailed wind

High demand for grid balancing e.g. % of renewables

Constraints on gas supply (e.g. parts of mid-Atlantic)

Demand for H2 vehicle fuel

Access to other hydrogen markets

Regulatory pressure on carbon

Great variations between winter and summer peak

Enlightened regulatory environment

Clean Fuel

Energy Storage




Competitive Advantages (PEM)

Responsive load

Nearly instantaneous response (ITM stacks 0.2 sec stack =

10 cycles)

Compatibility with gas grid (miscible, no need for additional

compression (ITM up to 80 bar))

Capacity and storage time effectively unlimited

Never “fills up”

Allows for long term (seasonal, annual) storage

Links electric grid to gas grid, heat demand, vehicle fuelling, water

purification, industrial markets

Clean Fuel

Energy Storage



R&D needs (synergy with PEM fuel cells)

Demonstrations at MW+ scale

Convince regulators and marketplace of viability

Mixing technology (and regulations)

Reliability (always available)

Durability (lasts a long time)

Cost reduction (synergies with PEM fuel cells)

Efficiency

Self pressurization to 700-800 bar

Clean Fuel

Energy Storage


CHALLENGES AND TECHNOLOGY DEVELOPMENTS

FORECOURT Challenges:

• Footprint requirements – Greenfield vs. Brownfield sites, storage capacity on site.

• Alkali verses PEM - ramp up / down response / footprint / gas purity / safety / pressure

• Power infrastructure – 1500kg/day = 3MW electrolyzer

Focus on Technology Developments. Continuous Improvements:

• Reduction in unit CAPEX costs – 50%

• Reduction in O&M costs – component selection

• Improvement in efficiency – 15-20%

• Packaging improvements.

• Overrun capacity 50% – make extra H2 when power prices low

• Focus on demand response linked to renewables

• Rain water/grey water harvest Clean Fuel
