The Water and Wastewater Companies for Climate Mitigation (WaCCliM) project supports water and wastewater utilities to reduce their carbon footprints and adapt to the impacts of climate change. Following a cross-sectoral approach that spans mitigation and adaptation, we consider the implications of greenhouse gases (GHGs) in the water–energy–carbon nexus.
Nearly two years into the Covid-19 pandemic, the renewable power projects on which the world relies to mitigate climate change face bigger challenges than when the coronavirus started to make headlines in 2020. As the global economy started to recover, commodity prices rose sharply and logistic bottlenecks wreaked havoc on supply chains, causing delays and eroding the margins of power equipment providers and project developers. At this point, unappealing profitability or even financial losses jeopardize investments on research, innovation, and capacity expansion. These were some of the problems discussed during the webinar The Future of Renewables: Insights from Industry Leaders, sponsored by Black & Veatch and held on January 12, 2022, as part of the Energy Leaders Series. To address these issues, the participating experts highlighted the need for new models and incentives to put the renewable power industry back on a profitable course that would enable a stable transition to a greener global energy matrix.
The Water Climate Discussion series creates a space to come together and help the water sector build its leading role in addressing the climate crisis. The series is the result of close collaboration between water institutions who recognise climate change as an
existential threat and wish to have a voice promoting a key message: water is climate. This report is based on the recorded third discussion of
the series: Energy Transitions, which was aired on Thursday, 1 July 2021. The discussion was hosted by Martin Currie and led by Ivan Vølund of VCS Denmark, John Sammon of Scottish Water Horizons and the interaction of the participants.
As the world recognizes the growing impacts of climate change, there is a sense of urgency to accelerate the transition to energy, transport and industrial systems with fewer greenhouse gas emissions and effectuate more sustainable modes of production
and consumption. To enable this transition, new energy carriers will be needed to transfer the increased levels of decarbonized energy
to consumers, without impacting the quality of service to residential, industrial and transportation users. Hydrogen offers
a versatile solution and is emerging as an increasingly important energy vector for decarbonized fuel sources, as well as for the storage and transport of renewable energy. Hydrogen is expected to play a critical role in decarbonizing power generation and transport, heating domestic and commercial buildings, and supporting industrial feedstock and industrial processes — including hard-to-abate sectors such as
steel, refining, cement and agriculture.
The Working Group II contribution to the IPCC Sixth Assessment Report assesses the impacts of climate change, looking at ecosystems, biodiversity, and human communities at global and regional levels. It also reviews vulnerabilities and the capacities and limits of the natural world and human societies to adapt to climate change.
The “Energy Performance and Carbon Emissions Assessment and Monitoring Tool” (ECAM) offers unique capabilities for assessing greenhouse gas (GHG) emissions and energy consumption of water and sanitation systems. Gain greater insights by identifying areas to reduce GHG emissions, increase energy savings and improve overall efficiencies to reduce costs.

Use of supervisory, control, and data acquisition (SCADA) system for monitoring, supervision and controlling of pumping systems can help minimize energy consumption of GHG emissions. It includes measurements in real time of water levels, pressures, flows, energy consumption and other operational parameters. It also helps to adjust and control the pump station operation, contributing to fight water losses or infiltration, reduce pumping during energy peak hours and adjust pumping volumes to the needs of the system. The SCADA systems provide utility managers with access to real-time operating data and can help offset the higher operating costs by minimizing unplanned downtime and improving maintenance plans. The SCADA system can also be used to optimize pumping in real-time through advanced pump optimization software and control, or through either a model-based or knowledge-based optimization that is implemented via a rule-based system programmed into the SCADA system. This type of optimization entails the use of algorithms to determine the best pumping scheme for a given situation. This can incorporate the peak energy times previously referenced, but also a prioritization of which pumps or pumping stations are used to maximize efficiency whenever possible. For example, if only a certain volume is demanded, then the SCADA system will first operate the most efficient pumps or pumping stations to meet the demand until greater capacity or more pumps are needed.
Based upon the system head conditions, pumps may be able to pump at higher rates than needed when operating at 100% motor speed. This flow rate can be controlled by one of two ways, throttling the pump with a valve if the pump is a constant speed pump, or changing the motor speed with a variable speed drive. The former is only energy efficient if the higher flow operating point of the pump without throttling is to the right of the best efficiency point on the pump performance curve, and the throttling results in reducing the flow to a point closer to the best efficiency point on the pump curve. Otherwise, throttling the pump can result in using more energy than at the higher flow, as well as wasting energy because you end up using more energy than is needed. When the demand on the system fluctuates significantly, the pumping rate can be controlled automatically by varying the speed of the motor with a variable frequency drive (VFD), such that the pump output matches only what is needed to meet demands or the intended pumping conditions. The pump’s flow rate then increases or decreases based upon the affinity laws and the controlled speed of the motor. This way lower pumping rates can be achieved, which may result in lower efficiency than those at full motor speed; however, the energy consumption is still lower because the energy requirements to pump lower flows at lower heads are lower.
