10% of global freshwater withdrawals to produce or process energy• <0.5% for fossil fuel extraction• ~0.5% for fuel refining and processing
Consumption considerably less: • Withdrawn volume for power production
~450km3/annum• Consumed volume for power production
<50km3/annum
Oil & gas sector has lowered freshwater demands across all activities:• e.g. 92% in freshwater withdrawals between
1997-2008 at BP Kwinana refinery, SW Australia
Clear opportunities to lower freshwater intensities further
The Energy Sustainability Challenge
Using non-fresh water sources such as sea
water, brackish water, produced water and
waste water in place of fresh water
Using the same water multiple times in an
industrial process
Treating wastewater to make it a usable
replacement for fresh water in another
application
Adapting practices to suit the local availability and demands on renewable
fresh water.
Large opportunities for water management
REPLACEMENT RE - USE REGIONAL RESPONSIBILITY
RECYCLING
• Local knowledge is essential• Water Resource availability and constraints
through watershed/aquifer basin approach• Understanding long term supply and
demand pressures• Local Regulatory, Reputational and
Economic Pressures
• Technology development
• Partnerships• Within the energy industry• Within the local area • e.g. Kwinana Refinery, Southwest Australia –
reuse and recycling
Kwinana Water Minimisation Project
• Partnership lead by BP comprising industries, local water company and regulatory authority
• Investment in tertiary treatment of water from municipal treatment plant for re-use as an alternative source of water
• Reduced BP total water withdrawals by 47% and freshwater withdrawals by 92%
• Reduced BP annual wastewater treatment costs by >30%
• Increased freshwater availability for municipality
Rising to the Challenge
